9 Best Aia Billing Software in 2026: Pricing, Features and Pros & Cons

Knowify is the AIA-first pick in this list. It builds licensed G702/G703 pay applications from the schedule of values: enter the percentage complete and stored materials, and Knowify applies retainage, folds in approved change orders and produces the forms a general contractor expects. The pay app and retainage data sync to QuickBooks in real time, so the invoice in the books always matches the application on the job.

The catch is the seat math. Core covers one user at $99 a month billed annually, and every extra user costs $29 a month, so a five-person office pays $215 a month. Job costing, budgets and WIP reporting sit on Advanced at $329 a month, which is the plan most growing firms need. Buy Knowify when AIA billing and QuickBooks are the job; look elsewhere if you need a ledger.

Contractor Foreman is the budget pick that still does real AIA billing. It generates native G702 and G703 pay applications with retainage tracking and lien waivers, and wraps them in a full all-in-one: estimating, scheduling, daily logs, time tracking, change orders and a QuickBooks sync. Pricing is a flat company rate rather than per seat, so adding field staff does not raise the bill once you are on the right tier.

The trade-off is polish and packaging. The interface feels less refined than JobTread or Buildertrend, and the pricing page does not map features to plans, so confirm that AIA billing sits on the tier you buy — Basic covers one user only, and a three-person office needs Standard at $105 a month billed annually. For a small crew that wants the most software per dollar, start here.

JobTread is the all-in-one pick for residential builders and remodelers. One plan includes everything: estimates that flow into budgets, purchase orders, schedules, time tracking, change orders, client portals and AIA-style pay applications, with QuickBooks Online as the accounting sync. Every account gets a dedicated customer success manager and free onboarding, and reviewers consistently praise the support team.

The honest limits are the form and the trial. JobTread added AIA-style billing in April 2026, but the forms are not licensed G702/G703 documents, so a commercial GC that requires the licensed version will not accept them. There is also no free trial — only a 30-day money-back guarantee on monthly plans. Buy JobTread when budgets and job costing are the job; buy Knowify when the licensed form is.

Siteline is the only tool in this list built exclusively for subcontractor billing. It pulls project data from your ERP, generates the pay application in whatever format each general contractor requires — AIA-style forms or one of more than 17,000 GC-specific formats already in its system — and tracks retainage, lien waivers, lower-tier waivers and collections in one workflow. It also submits directly to GC portals including Textura, GCPay and Procore Pay.

Siteline is not accounting software and does not replace your ERP; it sits alongside it and handles the monthly billing cycle. Pricing is a custom annual subscription based on billing volume and integrations, with unlimited users and offices and support included. Subcontractors have billed over $14 billion across more than 250,000 projects through Siteline, according to the vendor. If you bill many GCs in many formats, start here.

QuickBooks Online is the accounting backbone most small contractors already run, and Plus is the tier where it becomes useful for construction: project profitability, inventory tracking, budgets and class and location tracking for five users. Progress invoicing bills a fixed-price job in stages against the estimate, and the 30-day free trial or 50 percent off for three months makes it cheap to test.

What Plus cannot do is the AIA pay app. There is no native G702/G703 form and no retainage tracking, so commercial general contractors and lenders often reject a QuickBooks progress invoice as a pay application. The August 2026 increase also moved Plus from $115 to $140 a month, the second rise in eight months. Keep QuickBooks for the books and pair it with Knowify or Contractor Foreman for the pay apps.

Procore is the commercial standard in this list. Its Progress Billings tool generates standard AIA G702 and G703 forms from budgets, commitments and change orders, and subcontractor invoices, owner billing, lien waivers and disbursements live in the same project record as the schedule and the daily log. The platform syncs two ways with QuickBooks, Sage and other construction ERPs, and the annual fee includes unlimited users, storage and support.

The cost is the barrier: pricing is a custom annual fee per product based on annual construction volume, with no published figure and no free trial. Implementation and training take weeks, and a small firm will pay for depth — BIM, safety modules, field productivity — that it may never use. Buy Procore when you already run commercial projects on it; do not buy it for billing alone.

Buildertrend is the residential builder's platform: estimating, budgets, schedules, selections, client portal, warranty management and progress billing in one subscription with unlimited users and unlimited projects. It is built for builders who oversee five or more projects a year or handle complex multi-phase builds, and paying an annual plan upfront currently earns a 10 percent discount.

Two honest limits. Buildertrend no longer publishes pricing — the former Essential, Advanced and Complete tiers are gone, and the price now arrives as a custom quote after an intake form and a sales call. And its progress billing is not native AIA G702/G703, so commercial work that requires the form needs another tool. There is also no free trial; onboarding starts with a personalized demo. Buy it for residential builds, not for AIA billing.

Sage 100 Contractor is the veteran of this list: construction accounting, job costing, estimating, project management, payroll and service operations in one system, formerly sold as Sage Master Builder. Sage lists certified payroll, AIA billings and lien waivers among its strengths, and the system handles union and prevailing-wage payroll, percentage-of-completion accounting and multi-state certified reporting that QuickBooks cannot.

The price is the problem to solve first. Sage 100 Contractor is quote-only through Sage sales or partners, and third-party figures around $115 to $160 per user per month are unverified, so get a written quote early. The interface is desktop-era and the architecture is on-premise at heart, and implementation is heavier than a cloud add-on. Buy it when you are outgrowing QuickBooks and need certified payroll with your AIA billing.

Foundation Software — sold as FOUNDATION — is the accounting-first pick for midsize and large contractors. AIA-format G702 and G703 billing generates natively, with retainage, work-in-progress reporting, job costing by cost code, phase and category, certified payroll for prevailing wage and Davis-Bacon work, equipment tracking and 1099s. It is built for construction accounting from the ground up, not adapted from a generic ledger.

The trade-offs are price, time and interface. Pricing is a custom quote based on company size and modules, with third-party figures starting around $300 to $400 a month and climbing from there. Implementation takes weeks, the learning curve is steep, and the Windows-based interface feels dated next to cloud tools. Buy Foundation Software when the firm does $2 million-plus a year and the CPA wants the ledger and the pay apps in one system.
