FairBuild contract reviews use AI trained specifically on construction contracts to help subcontractors and suppliers review, redline, and negotiate terms better and faster.
FairBuild is AI contract review software built for U.S. construction subcontractors and material suppliers. It reviews subcontracts and supply agreements against construction-specific playbooks, flags risky clauses with plain-language summaries, and suggests alternative language you can apply, skip, or edit. You download a complete redline and can respond to your customer the same business day.
As a subcontractor, one of the biggest challenges we face is managing risk while also running day-to-day operations. FairBuild brings me the upfront visibility and awareness to potential contract risk.
Anyone who has a construction supply or subcontracting business could benefit from having FairBuild on their side. It was created by the leading legal and business minds with in-depth knowledge of our industry's unique contract issues.
It can be overwhelming to review a 30-page customer contract, so I rely on FairBuild's AI to identify problematic clauses and offer alternate language. FairBuild helps our team navigate our customer relationships with confidence.
FairBuild's AI contract review has changed how we handle customer agreements. We process complex contracts faster, catch risks earlier, and negotiate terms with much more confidence.
Built for your industry, not adapted to it.
See pricingGeneric AI tools miss what matters most in construction contracts. FairBuild has been trained on the clauses, risks, and industry standards that directly affect your bottom line, from retainage and payment terms to indemnity language and insurance requirements. This isn't general-purpose contract review. This is built for your industry.
Suppliers and subcontractors face different risks, so we built separate playbooks for each. GCs frequently use subcontract agreements for suppliers, loading them with requirements that don’t apply to material vendors and can inadvertently put a supplier in breach of state contractor laws. FairBuild’s supplier playbook catches exactly that. Our subcontractor playbook addresses the distinct project obligations subs face. The right tool for your role.
As you review each flagged issue, you can see exactly how a suggested change will look in the document. Then choose to apply it, skip it, or edit it to suit your needs. Tracked changes appear in real time. When you're done, download a complete redline instantly and respond to your customer in minutes, not days.
FairBuild AI takes you from contract received to a download-ready redline in three steps.
FairBuild is software for subcontractors and material suppliers in U.S. construction who review contracts from general contractors and customers, often without an in-house legal team. Current customers include glass, truss, millwork, building component, framing, paving, flooring, and playground installation companies.

Subscription renews annually. Join NowGeneral contractors have legal teams that write their subcontracts. Most subcontractors and suppliers don't have a lawyer on staff. That imbalance has led to unfavorable payment terms, buried indemnity clauses, and a lot of other contract language that shifts risk onto the businesses least equipped to absorb it.
FairBuild was built to close that gap. Our AI is trained specifically on construction industry contracts and gives subcontractors and suppliers the ability to review, understand, and redline contracts in minutes. It works with the specifics that matter in construction, which generic LLMs can't match. We also provide negotiating positions that we know work, because many GCs have accepted them across many projects.
So you can walk into every agreement with clarity, confidence, and a much stronger negotiating position.
About UsDon't sign until you know what you're agreeing to. FairBuild gives suppliers and subcontractors construction-specific contract intelligence, trained on the issues that actually show up on your jobs, in your agreements, and on your invoices. With Gen2, you can go from contract received to redline delivered in the same business day.
FairBuild's automated contract review uses AI trained on construction contracts to read your agreement against a subcontractor or supplier playbook. It flags risky clauses, ranks the issues that matter most to your business, and explains each one in plain language. Every flagged issue comes with suggested alternative language you can apply, skip, or edit.
With Gen2, you can go from contract received to redline delivered in the same business day, or within minutes if you want to. The AI review takes minutes, so most of your time goes to deciding how to handle each flagged issue. When you finish, you download a complete redline and respond to your customer in minutes, not days.
The subcontractor playbook covers the project obligations subs take on, such as payment, retainage, indemnity, insurance, and schedule terms. The supplier playbook catches subcontract requirements that do not fit a material vendor, which GCs often include in supply agreements. It also catches items of particular importance to suppliers, such as most favored pricing, design responsibility, and acceptance of deliveries. You can buy either playbook or both together.
FairBuild reviews construction subcontracts, supply agreements, and master agreements from general contractors and homebuilders. It also reviews the terms and conditions of purchase orders (not the scope or price) and can analyze AIA subcontract forms and purchase agreements.
FairBuild is construction contract software trained on the clauses, risks, and industry standards that matter specifically to subcontractors and suppliers. Retainage, payment terms, indemnity language, insurance requirements, and more can be negotiated better when you aren't starting from a generic AI review. FairBuild uses separate playbooks for subcontractors and suppliers, ranks issues by how much risk they carry, and produces a download-ready redline.
FairBuild uses organizational, technical, and administrative measures to protect your information. Your company controls who sees your contracts by assigning roles to its authorized users. The AI and cloud infrastructure providers FairBuild works with are contractually limited in how they can retain, use, or disclose your information. We don't use customer agreements to train FairBuild. Details are in our Privacy Policy.
FairBuild offers a Single Review for one document, plus annual subscriptions priced by the number of documents you review, from 6 to 50 documents a year. You can choose the subcontractor playbook, the supplier playbook, or both, with the second playbook at 50% off. See the Pricing page for current plans.
