What a Progress Payment Is

A progress payment is a partial payment made during a construction or service project, rather than waiting until the entire job is finished. Instead of paying the contractor or vendor once at the end, you pay them in stages as they complete defined portions of the work. Each payment is tied to a specific milestone — foundation complete, framing done, electrical rough-in finished — so both you and the contractor know exactly what has been paid for.

Progress payments protect both parties. The contractor gets cash flow to buy materials and pay workers as the project moves forward, rather than funding the entire job out of pocket. You avoid paying for work that hasn't been done yet and can inspect each phase before releasing the next payment.

These payments are standard in construction, renovation, landscaping, and any project that unfolds over weeks or months. They're also common in custom manufacturing, software development, and other work where the final product takes time to create.

Key Takeaways

  • Progress payments are scheduled payments released as the contractor completes defined stages of work, not a lump sum at the end.
  • Each payment is usually tied to a specific milestone or percentage of work completed, which you can inspect before paying.
  • The payment schedule and milestones should be written into the contract before work begins, so there is no disagreement later.
  • A retainage amount — typically 5 to 10 percent of the total contract price — is usually held back until final completion and inspection.
  • Progress payments require clear documentation: invoices, proof of work completion, and sometimes a third-party inspector's sign-off.

How the Payment Schedule Gets Set Up

Before any work starts, you and the contractor agree on a payment schedule and put it in writing in the contract. This schedule lists the milestones, the percentage or dollar amount due at each one, and the timeline. A typical residential renovation might have payments at foundation, framing, rough-in (electrical and plumbing), drywall, and final completion. A larger commercial project might have ten or more stages.

The schedule should be specific enough that both parties agree on what "complete" means. "Foundation complete" is clearer than "early stage work done." Some contracts tie payments to a percentage of total work — 25 percent at framing, 50 percent at rough-in, 75 percent at finish, 100 percent at final — while others use dollar amounts or a combination.

The contract should also state who inspects the work before each payment is released. This might be you, a hired inspector, the architect or engineer overseeing the project, or a combination. The inspection step is what makes progress payments work: you see the work before you pay for it.

What Happens at Each Payment Milestone

When the contractor believes a milestone is complete, they submit an invoice or progress billing statement. This document describes the work done, references the contract milestone, and requests payment. Some contractors include photos or a site report; others rely on a site visit.

You (or your inspector) then visit the site and verify that the work matches the description. If it does, you approve the payment. If there are defects, incomplete work, or materials that don't match the contract, you can withhold payment or request corrections before paying. This is your leverage point — the contractor has incentive to do the work right because the next payment depends on it.

Once you approve, you send payment to the contractor. The timeframe for payment should be in the contract — typically 7 to 14 days after approval. Some contracts allow the contractor to charge interest if payment is late.

Retainage: The Money Held Back Until the End

Most construction contracts include retainage, a percentage of each progress payment that you hold back and release only after the entire project is complete and inspected. Retainage is typically 5 to 10 percent of the contract price, though it varies by industry and region.

Retainage protects you if the contractor leaves the job unfinished, does poor work, or doesn't pay their suppliers and workers. If the contractor abandons the project, you have funds to hire someone else to complete it. If there are defects, you can use retainage to pay for repairs without going back to court.

The contractor dislikes retainage because it ties up their money, but it's standard practice. Some contracts reduce retainage as the project nears completion — for example, 10 percent on early payments, 5 percent on later ones — to give the contractor some relief while still protecting you.

Retainage is released after final inspection and sign-off. The contract should specify the timeline — usually 30 to 60 days after project completion — and any conditions, such as proof that all suppliers and workers have been paid.

Documentation You'll Need

Progress payments require a paper trail. At minimum, keep copies of the contract with the payment schedule, each progress invoice or billing statement, your inspection notes or photos, and proof of payment (cancelled check, bank transfer receipt, or credit card statement). If a third party inspects, keep their sign-off or report as well.

This documentation protects you if a dispute arises later. If the contractor claims you didn't pay for a certain stage, or if you need to prove the work was defective, your records show what was paid, when, and what condition the work was in at that time. It also matters for tax purposes: you may need to document progress payments for deductions or to prove you paid for work in a particular year.

Some larger projects use a formal progress payment form or lien waiver. A lien waiver is a document the contractor signs stating they have been paid for work through a certain date and waive their right to file a lien (a legal claim against your property) for that portion of work. Lien waivers are common in construction and protect you from a contractor claiming they were never paid and then placing a lien on your home or building.

What Happens If Work Stops or Quality Is Poor

If the contractor stops working or does substandard work, you can withhold payment for that milestone. The contract should specify what happens in this case — typically, you notify the contractor in writing and give them a important date to fix the problem or resume work. If they don't, you may have the right to hire someone else to complete or repair the work and deduct that cost from the progress payment or retainage.

If the contractor disputes your withholding and believes they deserve payment, the contract should outline how disputes are resolved — through negotiation, mediation, or arbitration. Going to court over a single progress payment is expensive, so most contracts try to avoid it by building in a dispute process.

If you withhold payment, document your reasons in writing and keep photos or inspection reports showing the defect or incomplete work. This protects you if the contractor sues or if the dispute goes to mediation.

Progress Payments vs. Lump-Sum and Cost-Plus Contracts

Progress payments are one way to structure payment; others exist. A lump-sum contract sets a fixed total price, and you pay it all at the end (or sometimes in two payments: half at start, half at completion). This puts all the financial risk on the contractor — if costs rise, they absorb it. It's simpler but gives you less control over the project timeline and quality.

A cost-plus contract reimburses the contractor for actual costs (materials, labor, equipment) plus a markup or fee. Progress payments are common in cost-plus work because you need to pay for materials as they're purchased. This gives you more transparency but less predictability on final cost.

Progress payments work best for fixed-price contracts where the scope is clear and can be divided into stages. They give you control and the contractor cash flow, making them the standard for construction and renovation.

Frequently Asked Questions

Can I refuse to pay a progress payment if I'm unhappy with the work?

Yes, you can withhold payment if the work is incomplete or defective. However, the contract should specify what constitutes acceptable completion and what your process is for rejecting work. Document the problem with photos or an inspection report, and give the contractor written notice and a important date to fix it. If they refuse or can't fix it, you may have the right to hire someone else and deduct the cost from their payment or retainage.

What if the contractor asks for payment before the work is done?

Don't pay until the milestone is complete and inspected. The contract payment schedule protects you by tying payment to completion. If the contractor asks for early payment, they're asking you to take on risk they should bear. Stick to the schedule unless you agree in writing to change it — and if you do, reduce the next payment by the same amount so the total stays the same.

Is retainage the same as a down payment?

No. A down payment is money you pay upfront before work starts, usually to cover the contractor's initial costs. Retainage is money you hold back from progress payments and release at the end. Down payments and retainage serve different purposes and can both be in the same contract.

What if the contractor goes out of business before finishing?

If you've been making progress payments and holding retainage, you have funds left to hire another contractor to complete the work. This is why retainage matters. If you had paid in full upfront, you'd have no recourse. Make sure your contract allows you to use retainage for completion if the original contractor can't finish.

Do I need a lawyer to set up a progress payment schedule?

For small projects, a clear written agreement with the contractor that lists milestones and payment amounts is usually enough. For larger projects or if the contract is complex, a lawyer can review it and make sure your interests are protected. At minimum, get the payment schedule in writing before work starts — verbal agreements lead to disputes.
