Back-office AI in construction: what Adaptive, Miter, Siteline, Built, and Constrafor say the AI does

Where AI shows up in the back office

Our framing, not a vendor claim: the five vendors here fall on a spectrum. Adaptive sells AI agents as the product. Miter and Built describe AI features inside broader platforms (payroll and HR for Miter, construction lending for Built). Siteline lists one AI feature on its pricing page but does not market itself as AI. Constrafor's homepage does not describe AI at all; it is included because GCs evaluating back-office automation are likely to see it alongside the others.

AI agents for project accounting: Adaptive

Adaptive calls itself an AI-native project accounting platform for construction. It lists agents it describes as a WIP and forecasting analyst, a change order clerk, an AP clerk that ingests invoices, codes them to job and cost code, and catches duplicates and fraud, a billings clerk for cost-plus, fixed-price, and AIA billing, a cards and bank reconciliation clerk, lien waiver and insurance tracking clerks, and a field coordinator that calls supers and PMs and collects updates by voice, text, or email.

Two statements stand out for buyers worried about AI on the books. Adaptive says it does not replace the ERP: the general ledger stays in Sage, QuickBooks, Foundation, or Acumatica, and Adaptive exports reviewed numbers into it, with a bidirectional Procore integration for customers who use both. And its FAQ says the AI never auto-posts to the GL and every action is reviewed by a human before it touches the books (vendor statements). It says it is built for construction companies with $5M to $1B in revenue and that more than 750 builders use it (vendor claim).

Pricing: not publicly listed. Adaptive's pricing page describes a monthly base fee scaled to your revenue band that covers configuring and tuning a first agent, with additional agents scoped up front. It lists month-to-month contracts, 30 to 90 days to go live, unlimited users, no per-seat or transaction fees, full data export, and SOC 2 Type 2.

AI inside a payroll and workforce platform: Miter

Miter's homepage describes construction workforce management covering payroll, HR, recruiting, benefits, expense management, and field operations (time tracking, production, equipment, photos, schedules, and daily reports), plus certified, union, and prevailing-wage payroll and job costing. The homepage itself does not itemize AI features.

The AI detail comes from Miter's Sept. 30, 2026 Series B announcement. There, Miter says its technology parses and structures data in invoices, receipts, and pay rate tables, runs workflows contractors previously did by hand, and surfaces labor and job-cost trends while a job is still running; in the field, it says its AI creates safety reports from photos or voice notes and summarizes job status. Miter says more than 2,000 contractors run payroll, HR, field operations, and expense management on it (company claims). Pricing: not publicly listed; miter.com/pricing returned a 404 on Oct 15.

Subcontractor billing with one AI feature: Siteline

Siteline is billing software for commercial subcontractors: pay apps on each GC's forms, submission by email or through GC payment portals (it names Textura, GCPay, and Procore Pay), lien waivers, compliance documents, collections, and cash-flow forecasting, alongside the subcontractor's existing accounting system. Its homepage does not describe the product as AI, which is why our directory tags it Not AI-first. Its pricing page does list “AI vendor waiver validation for incorrect forms, amounts, or dates” as part of the Siteline Suite.

Siteline's pages cite getting paid 3 weeks faster and billing 6x faster (vendor claims). The same pricing page gives two different invoice-aging figures, a 43% reduction in one place and 30% in its FAQ, so ask which applies and how it was measured. Pricing: not publicly listed; Siteline offers a custom quote based on product usage, billing volume, and integration needs, and says every package includes unlimited users and offices with no per-seat or location fees.

AI for construction lenders: Built Technologies

Built describes a real estate and construction finance platform for lenders, owners and developers, and builders. It says its AI is trained on $3T+ of real estate finance data, lists AI-powered draw inspections that catch issues before funds move, and promotes an AI Draw Agent that it says enables 2–5× capacity gains, 100% policy adherence, 2× more risks flagged, and up to 95% faster draw processing (vendor claims, not verified). It lists integrations with Sage, Yardi, Procore and more, and cites $300B+ of capital managed, 78,000+ owners and contractors, and 340+ lenders on Built (vendor claims). Our read, not a vendor claim: for a contractor, Built is most likely to show up through the lender, as the system used to review draws. Pricing: not publicly listed.

Subcontract risk without an AI pitch: Constrafor

Constrafor describes construction-first risk management software for general contractors (contract management, subcontractor onboarding and prequalification, certificate-of-insurance management, invoice management, and payment processing) and growth solutions for subcontractors, including invoice financing. Its homepage does not describe AI features. It cites a 40,000+ contractor network, $2 billion+ of invoices financed, and $10 billion+ of COIs managed (vendor claims), and invites visitors to explore the platform for free. Software pricing is not publicly listed on the homepage.

What to ask before a pilot

These are our suggestions, not findings. Ask exactly which steps the AI performs on its own and which a person approves; Adaptive puts this in writing, so ask the others for the same. Run a month of real invoices, pay apps, or payroll through the pilot and count corrections. Confirm your ERP and GC payment portals are on the supported list rather than on a roadmap. Ask who is responsible when an AI-checked lien waiver or certified payroll report is wrong. And because pricing units differ (revenue band, custom quote, per-agent scope), ask each vendor for a written price on the same scope.
