12 Best Construction Billing & Progress Billing Software for Contractors in 2026

Last Updated on October 15, 2026 by ConstructionPlacements Editorial Team

Construction billing software helps contractors create, submit, track and collect invoices and payment applications while handling construction-specific requirements such as progress billing, schedules of values, retainage, stored materials, change orders, subcontractor billing and project-level financial controls.

Unlike ordinary invoicing software, the best construction billing software in 2026 is built around the way contractors are actually paid. On commercial projects, a contractor may need to bill only for work completed during a specific period, account for previously billed amounts, add approved change orders, identify materials stored on or off site, withhold retainage and support the entire payment application with contract-specific documentation.

That makes construction billing a critical link between project progress, job costing, accounting and cash flow.
For contractors in India, construction billing may also involve GST-compliant invoices, running account (RA) bills, measurement-based quantities, retention deductions and project-wise payment reconciliation. These requirements are covered in a dedicated India section below, alongside the international software comparisons.

Editorial disclosure: ConstructionPlacements researched this guide using current official vendor websites, product documentation and help resources available in October 2026. This ranking is based on publicly verifiable capabilities and suitability for different construction workflows; it is not presented as a hands-on laboratory test of every platform. Software functionality, packaging, integrations and pricing change frequently, so contractors should verify current information directly with shortlisted vendors before purchasing. Paid placement does not determine the editorial order of this list.

Best Construction Billing Software: Quick Comparison

Important: “AIA-style” billing and licensed AIA Contract Documents are not necessarily the same thing. Some software can reproduce the calculations and workflow associated with G702/G703-style payment applications, while access to official branded forms may depend on a vendor’s licensing arrangement, integration or separate document licence. Confirm this requirement directly with the software provider if your contract specifically requires official AIA forms.

How We Evaluated Construction Billing Software

Construction billing involves more than generating an invoice PDF. We evaluated platforms according to the workflows most likely to delay contractor payment when they are poorly managed.

• Progress billing: ability to bill incrementally as work is completed.
• Schedule of values: support for contract line items and cumulative billing.
• Prior billing: ability to carry forward previous applications correctly.
• Retainage: tracking amounts withheld and subsequently released.
• Stored materials: ability to bill or track materials stored where permitted by the contract.
• Change orders: connection between approved contract changes and billing value.
• Subcontractor billing: collection, review and approval of subcontractor payment applications.
• Owner billing: generation of the contractor’s billing to the client or owner.
• Lien waivers and compliance: where applicable, connection between payment and required documentation.
• Accounting integration: reducing duplicate entry between billing and financial systems.
• Payment collection: electronic payments, invoice tracking and accounts-receivable visibility.
• Contractor fit: suitability for GCs, specialty trades, residential builders, subcontractors or enterprise owners.

We deliberately avoid assigning artificial decimal scores because an enterprise payment-management system such as Oracle Textura serves a very different buyer from Buildertrend or Contractor Foreman.

What Is Construction Billing Software?

Construction billing software is a system used to prepare, submit, track and reconcile invoices or payment applications for construction work.

Depending on the contract and project type, a billing application may need to account for:

• Original contract value
• Schedule of values
• Approved change orders
• Work completed during the current period
• Previously completed work
• Materials presently stored
• Previous applications for payment
• Retainage or retention
• Taxes
• Current payment due
• Remaining contract balance
• Lien waivers
• Compliance documents

The American Institute of Architects’ commonly used G702 and G703 payment documents illustrate why commercial construction billing is fundamentally different from a standard business invoice. AIA explains that the G702 application includes contract value, work completed and stored to date, retainage, previous payments, change orders and the current amount requested, while the G703 continuation sheet provides the detailed breakdown of portions of the work.

12 Best Construction Billing & Progress Billing Software Platforms in 2026

1. FOUNDATION — Best Overall Construction Billing + Accounting Software

Best for: General contractors and specialty contractors that want progress billing, job costing and construction accounting in the same system.

FOUNDATION is our top overall selection because construction billing is directly integrated with the accounting transactions that determine project financial performance.

FOUNDATION supports multiple billing approaches, including AIA progress billing, percentage-complete billing, time-and-material billing, unit-price billing and conventional invoicing.

Its Accounts Receivable module can generate lump-sum and percent-complete invoices, while FOUNDATION’s construction-specific workflows maintain billing information alongside job cost, accounts receivable and project financial data.

For progress billing, FOUNDATION can maintain successive applications rather than forcing contractors to reconstruct cumulative billing history manually. Its AIA billing workflow also supports schedules of values, previous billing information and retainage.

Key billing capabilities

• Progress billing
• AIA-style billing workflows
• Schedule-of-values billing
• Retainage tracking and release
• Percentage-complete invoices
• Time-and-material billing
• Unit-price billing
• Recurring billing
• Accounts receivable
• Job-cost integration
• WIP and over/underbilling visibility
• Project-management integration through the wider FOUNDATION ecosystem

Why it stands out: Billing is not isolated from accounting. When the accounting system already understands the job, contract, cost structure and receivable, fewer financial records need to be recreated elsewhere.

Potential limitation: Organizations primarily looking for a stand-alone subcontractor pay-application portal may prefer Siteline or GCPay rather than implementing a broader accounting system.

Pricing: Custom quote based on modules and company requirements.

Official sources: FOUNDATION Accounts Receivable and FOUNDATION AIA Billing

Best Construction Billing Software for Indian Contractors: GST, RA Bills & Civil Projects

For Indian construction companies, the right billing software depends on whether the main requirement is GST invoicing or contract-based civil construction billing. A small contractor generating stage-wise invoices and monitoring payments may need a simpler system than an infrastructure contractor submitting running account (RA) bills against certified quantities and detailed measurement records.

What Is RA Billing in Construction?

A running account bill (RA bill) is an interim bill submitted for work executed during an ongoing construction contract. Depending on contract terms, it may be supported by measurement books or other quantity records, approved item rates, earlier bills, recoveries, retention or security deductions, and certification by the engineer or client.

RA billing is related to progress billing but should not be treated as identical to an American AIA G702/G703 payment application. Government, infrastructure and private construction clients in India may specify their own measurement and billing formats, approval sequences and contractual deductions. Check the particular tender and contract before choosing software.

Key Features to Check for Civil Billing Software in India

• GST invoicing: Correct GSTIN information, HSN/SAC details and tax treatment appropriate to the transaction.
• RA and progressive billing: Cumulative billed quantities and values, previous-bill adjustments and project-wise outstanding balances.
• Measurement-based billing: Links between BOQ items, measurements, approved quantities, item rates and submitted bills where required.
• Retention and recoveries: Tracking retention/security deductions, advances, material recoveries and their later adjustment.
• Milestones and variations: Tracking certified progress, approved extra items and contract changes.
• Documents and approvals: Exportable bill abstracts, supporting documents, customer-specific formats and an auditable approval trail.
• Accounting and collections: Project ledgers, receivables ageing, payment receipts and accounting integrations.
• Statutory workflows: Applicable GST e-invoicing, e-way bill and reporting requirements, where relevant to the business.

myBillBook — India-Focused GST and Project Billing Option

Best for: Indian builders, small and midsize contractors, and construction-related businesses prioritizing GST invoices, stage-wise billing, payment tracking and inventory-related transactions.

myBillBook is worth comparing because its construction invoicing information describes project-wise invoicing, milestone or running-bill workflows, labour and material billing, payment reminders and GST-ready invoices. Its related construction accounting information also describes inventory, accounts-receivable and accounts-payable tools and options for e-invoicing and e-way bills.

Key capabilities to evaluate:

• GST and non-GST invoice creation, with applicable tax details.
• Project-wise and milestone-based invoicing.
• Running-bill and outstanding-payment workflows described by the vendor.
• Customer, contractor and supplier ledgers.
• Inventory and material-related invoice tracking.
• Electronic invoice and e-way bill facilities where supported and applicable.

Potential limitation: Do not assume that a vendor’s reference to RA bills guarantees every engineer-certified civil billing format. For large infrastructure or government contracts, ask for a live demonstration of BOQ-linked measurements, prior RA bills, approval formats, recoveries and contract-specific deductions. Confirm which features are included in the chosen plan.

Official sources: myBillBook Construction Invoicing and myBillBook Construction Accounting.

GST Invoicing vs. Construction RA Billing: Why the Distinction Matters

GST invoicing and RA billing solve related but different problems. A GST tax invoice records a taxable supply and its applicable tax details. An RA bill records and seeks approval or payment for work measured or certified under the construction contract. Depending on the arrangement, the RA bill and the tax invoice may be separate documents with different timings and requirements.

For statutory invoice particulars, refer to the Central Board of Indirect Taxes and Customs (CBIC) GST invoice rules. Businesses subject to e-invoicing requirements can also review information from a GSTN-authorized invoice registration portal. Applicability and operational rules can change, so confirm current obligations with a qualified GST professional instead of assuming that every contractor must generate an e-invoice or e-way bill for every transaction.

Practical recommendation: For basic GST invoices, stage-wise customer bills and receivable tracking, evaluate myBillBook alongside other India-focused options. For complex certified RA bills, quantity-based infrastructure contracts or multi-company project accounting, prioritize a system that can demonstrate the specific contract’s measurement, certification, retention and reconciliation workflow. Verify Indian tax support and local availability before shortlisting any international construction ERP.

Best Construction Billing Software by Contractor Type

How Construction Progress Billing Works

Progress billing allows a contractor to invoice incrementally as a project progresses rather than waiting until the entire job is complete.

A simplified billing cycle might look like this:

For example, assume a contractor has a $1,000,000 contract.

• Work completed and stored to date: $400,000
• Retainage: 5%
• Earned less retainage: $380,000
• Previously certified/paid: $250,000
• Current payment request: $130,000

The exact calculation depends on the contract, billing method and jurisdiction, but the principle is cumulative: each application normally needs to understand what was billed previously as well as what is being requested now.

What Is AIA Billing?

AIA billing commonly refers to payment-application workflows based on forms published by AIA Contract Documents.

For standard owner-contractor progress billing, two of the most widely recognised forms are:

• G702 — Application and Certificate for Payment
• G703 — Continuation Sheet

AIA states that G702 is used for the contractor’s payment application and architect’s certification, while G703 provides the continuation sheet that breaks the contract sum into individual portions of work.

The documents account for items such as:

• Original contract sum
• Net change orders
• Contract sum to date
• Work completed
• Stored materials
• Retainage
• Previous payments
• Current payment due
• Balance to finish

AIA also publishes different payment forms for other contractual structures, including cost-of-the-work, subcontractor and design-build arrangements.

Authoritative source: AIA Contract Documents — Payment Application Form Variations

What Is a Schedule of Values?

A schedule of values (SOV) allocates the total contract value across specific portions of the work.

A simplified SOV might look like this:

An SOV therefore does much more than itemize the invoice. It becomes the structure against which contract progress is billed over multiple periods.

What Is Retainage in Construction Billing?

Retainage, also called retention, is a portion of an otherwise earned payment that is withheld until contract conditions or completion milestones are satisfied.

A billing platform may need to handle:

• Retainage percentage by contract
• Separate work and stored-material retainage
• Different retainage rates by line item
• Reduction of retainage after a milestone
• Partial retainage release
• Final retainage billing
• Subcontractor retainage
• Owner retainage

Retainage requirements vary by contract and jurisdiction. Software should automate the agreed calculation, but it does not replace legal or accounting review of the applicable contract and local requirements.

How Stored Materials Affect Progress Billing

Many progress-payment arrangements allow certain stored materials to be included in a payment application even though those materials have not yet been permanently installed.

Billing software may therefore need to distinguish:

• Work completed
• Materials currently stored
• Previously stored materials now installed
• Retainage on completed work
• Retainage on stored materials

Whether particular stored materials are billable depends on the contract, documentation and project requirements.

How Change Orders Affect Construction Billing

Approved changes can alter both the contract value and the amount the contractor is entitled to bill.

The billing system should clearly distinguish:

Original Contract + Approved Change Orders = Current Contract Value.

Potential or unapproved changes should not automatically become billable simply because the work has begun.

For contractors managing a large volume of scope changes, see our comparison of the best construction change order management software.

Construction Billing Software vs Invoicing Software

A residential service contractor may be perfectly satisfied with conventional invoicing. A commercial subcontractor submitting 100 monthly pay applications generally will not be.

Construction Billing Software vs Construction Accounting Software

Billing determines what the contractor requests and collects from the customer. Accounting records the financial effects of those transactions across the business.

Construction accounting typically includes:

• General ledger
• Accounts payable
• Accounts receivable
• Job costing
• Payroll
• WIP reporting
• Financial statements

Some systems such as FOUNDATION and Sage 100 Contractor combine billing and accounting. Others, such as Siteline and GCPay, specialize in the billing/payment workflow and integrate with accounting systems.

See our detailed comparison of the best construction accounting software.

Construction Billing vs Accounts Payable

This distinction is easy to confuse:

Construction billing / Accounts Receivable: money the contractor is trying to collect.

Accounts Payable: money the contractor owes suppliers and subcontractors.

A general contractor often sits in the middle of both processes:

To automate the supplier/vendor side of the process, compare the best construction accounts payable software.

UK subcontractor payment requirements: Construction billing and subcontractor payment processing should account for applicable local tax obligations. In the United Kingdom, contractors may need software supporting CIS deductions, subcontractor verification and monthly HMRC reporting. Compare the best CIS payroll and construction accounting software in the UK to evaluate these requirements alongside everyday invoice and payment management.

How Job Costing Connects to Billing

Billing and job costing answer different questions.

Job costing: What is the project costing us?

Billing: What are we entitled to collect?

A project can be:

• profitable but underbilled,
• profitable and overbilled,
• unprofitable but temporarily cash-positive, or
• unprofitable and underbilled.

This is why billing should be reviewed alongside project cost and WIP information rather than in isolation.

See our new guide to the best construction job costing software.

Time-and-Material Billing Software

Under a time-and-material contract, the contractor bills according to agreed labour, materials, equipment and other reimbursable costs, often with agreed markups or fees.

Effective T&M billing software should be able to capture:

• Employee time
• Labour rates
• Equipment hours
• Material purchases
• Subcontracted work
• Receipts
• Approved markups
• Supporting documentation

The biggest risk with T&M work is frequently not calculation—it is failing to capture billable activity before the invoice is prepared.

Unit-Price Billing

Unit-price contracts bill according to measured quantities multiplied by agreed unit rates.

Examples include:

• Cubic metres/yards of excavation
• Linear feet/metres of pipe
• Square metres/feet of paving
• Tons of asphalt
• Units installed

Heavy-civil and infrastructure contractors should verify that a billing platform can connect field quantities with approved contract items rather than forcing users to calculate quantities externally.

Construction Billing and WIP

Billing does not automatically equal revenue earned.

Construction companies may need to compare:

• Cost incurred
• Estimated cost to complete
• Percentage complete
• Revenue earned
• Amount billed

This produces concepts such as:

Overbilling: cumulative billings exceed revenue recognized/earned under the company’s accounting method.

Underbilling: earned revenue exceeds cumulative billings.

The exact accounting treatment depends on applicable standards, contract structure and company policy, so contractors should work with qualified construction-accounting professionals.

Lien Waivers and Construction Billing

On many US construction projects, payment workflows involve conditional or unconditional lien waivers.

A strong payment-management platform may:

• Generate required waivers
• Collect subcontractor waivers
• Collect lower-tier waivers
• Track missing documents
• Prevent payment release until requirements are met
• Exchange unconditional waivers with electronic payment

This is an area where specialist platforms such as GCPay and Oracle Textura can provide substantially more control than standard invoicing applications.

Features to Look for in Construction Billing Software

1. Progress Billing

The system should carry cumulative values from one billing period to the next without forcing users to rebuild calculations.

2. Schedule of Values

The billing structure should align with the contract and required work breakdown.

3. Retainage

Software should track withheld funds accurately and support release workflows.

4. Stored Materials

Commercial contractors should verify whether stored-material values and related retainage can be handled correctly.

5. Change Orders

Approved changes should update contract values and billing schedules without corrupting original contract history.

6. Prior Billing

Every new payment application must understand what has already been billed.

7. Subcontractor Billing

GCs should be able to collect, review and approve trade partner applications efficiently.

8. Owner Billing

General contractors should be able to translate project progress and subcontractor billing into an accurate owner application.

9. Compliance & Lien Waivers

For US commercial construction, these documents can be as important to payment timing as the invoice itself.

10. Accounting Integration

Approved billing should not need to be recreated manually in the general ledger or accounts receivable.

11. Online Payments

Residential and smaller contractors may benefit significantly from integrated ACH and card collection.

12. A/R Reporting

Contractors should be able to see what has been billed, approved, rejected, outstanding and overdue.

Construction Billing Software Selection Scorecard

A residential builder may shift much of the compliance weighting toward client payments and ease of use. A large commercial GC should do the opposite.

Construction Billing Software Demo Checklist

Give every vendor the same billing scenario.

If the software cannot clearly demonstrate the workflows your contracts require, a long feature list should not outweigh that gap.

Frequently Asked Questions About Construction Billing Software

What is construction billing software?

Construction billing software helps contractors create and manage invoices or payment applications for construction work. It may include progress billing, schedules of values, retainage, stored materials, change orders, pay applications, lien waivers and integration with accounting or project-management systems.

What is progress billing in construction?

Progress billing allows contractors to bill incrementally based on work completed during a project rather than invoicing the entire contract at the beginning or end. Each billing period normally considers prior billing, current work, stored materials, change orders and retainage.

What is the best construction billing software?

FOUNDATION is a strong overall choice for integrated accounting and billing. Siteline is especially strong for subcontractors, GCPay for GCs managing subcontractor pay apps, Procore for project financial workflows, Oracle Textura for enterprise payment management, Knowify for trade contractors, and Buildertrend for residential builders.

What is AIA billing software?

AIA billing software helps contractors prepare payment applications based on workflows associated with AIA payment documents such as G702 and G703. Contractors should verify whether software generates AIA-style output or is authorized to provide official licensed AIA Contract Documents.

What is a G702?

AIA Document G702 is the Application and Certificate for Payment used for certain owner-contractor payment applications. It summarizes contract value, approved changes, work completed, stored materials, retainage, previous payments and current payment requested.

What is a G703?

G703 is the continuation sheet used with the G702 process. It provides a detailed breakdown of portions of the work, scheduled values, completed work, stored materials and retainage.

What is a schedule of values?

A schedule of values allocates a construction contract’s total value across defined work items or portions of work. It provides the structure used to measure and bill progress over the life of the project.

What is retainage?

Retainage is a portion of otherwise earned payment withheld according to contract terms until specified completion requirements or milestones are satisfied. Requirements vary by project and jurisdiction.

Can construction billing software handle stored materials?

Many commercial construction billing platforms can track stored materials separately from installed work. Whether those materials can be billed depends on the project’s contract and supporting documentation requirements.

Can QuickBooks do construction progress billing?

QuickBooks can support invoicing and certain progress invoicing workflows, but many contractors add construction-specific platforms such as Knowify when they require AIA-style applications, retainage, stored materials, schedules of values and project-specific financial workflows.

Is construction billing software the same as accounting software?

No. Billing software manages what the contractor requests and collects from customers, while accounting software maintains the broader financial records of the business. Some construction systems combine both functions.

What is the difference between a pay application and an invoice?

A conventional invoice typically requests payment for specific goods or services. A construction payment application often represents cumulative progress against a contract and may include a schedule of values, previous billings, retainage, stored materials and certification or supporting documentation.

What is subcontractor billing software?

Subcontractor billing software helps specialty contractors prepare and submit pay applications, track retainage, manage change orders, collect lien waivers and monitor outstanding accounts receivable across multiple general contractors.

What is construction payment management software?

Construction payment management software extends beyond invoicing by connecting payment applications, approvals, compliance, lien waivers, payment release and sometimes electronic payments across owners, general contractors and subcontractors.

What is T&M billing?

Time-and-material billing charges the customer according to agreed labour, materials, equipment and other reimbursable project costs, usually subject to contractual rates and markups.

Which billing software is suitable for Indian construction companies?

For Indian businesses prioritizing GST invoices, milestone billing and payment tracking, myBillBook is an option to compare. For public works or complex civil projects, confirm that the shortlisted system supports contract-specific RA bills, approved measurements, BOQ items, recoveries, certification and applicable GST requirements.

What is an RA bill in civil construction?

A running account (RA) bill is an interim payment claim for work performed under an ongoing construction contract. It can include measured quantities, agreed rates, previous billing, deductions and certification as required by the client and contract.

Is GST billing software the same as civil construction billing software?

No. GST billing software focuses on compliant tax invoices and related transaction records. Civil construction billing software may additionally require quantity measurement, BOQ-linked item billing, RA bill preparation, retention, approval documentation and project-wise financial reconciliation. Some products combine parts of both workflows.

Do Deltek ComputerEase and Jonas Construction support construction progress billing?

Their official product pages describe construction-specific billing capabilities. Deltek ComputerEase lists AIA and unit billing, while Jonas Construction lists progress, AIA, time-and-material, cost-plus, flat-rate and unit-price billing. Verify editions, contractual forms, pricing and regional availability directly with each vendor.

Final Verdict

Construction billing software should solve a simple but financially critical problem:

turn completed, contractually billable construction work into an accurate payment request—and then help the contractor collect that money.

The best platform depends on where your billing complexity actually sits.

• FOUNDATION is our strongest overall choice when billing and construction accounting need to operate together.
• Siteline is particularly compelling for commercial subcontractors dealing with many GC-specific billing requirements.
• GCPay is one of the strongest options for GCs managing subcontractor payment applications and compliance.
• Procore is well suited to teams already managing project financials, commitments and changes within its ecosystem.
• Sage 100 Contractor provides mature progress billing tied directly to job cost and accounting.
• Oracle Textura is designed for enterprise-level construction payment workflows and governance.
• Payapps deserves serious consideration in Australia and New Zealand.
• Acumatica is attractive when billing must sit inside a broader cloud ERP.
• JobTread gives smaller and midsize contractors an accessible all-in-one option.
• Knowify is especially strong for commercial trade contractors using QuickBooks.
• Buildertrend is highly relevant for residential construction.
• Contractor Foreman provides substantial billing functionality for cost-conscious smaller contractors.

Before selecting software, take one of your most difficult real payment applications—including retainage, stored materials, changes and prior billing—and make every shortlisted vendor demonstrate the entire process.

That will reveal much more than a feature checklist.
For Indian construction businesses: myBillBook is a relevant option for GST, project invoicing and running-bill needs, while more complex measured civil works require explicit verification of RA-bill and certification workflows. Deltek ComputerEase and Jonas Construction are additional accounting-led alternatives for contractors comparing billing methods; they are not part of the 12-product ranking.
