Payment terms

How payment terms work

Payment terms are the rules for money on a job. They cover four things: how much is paid up front, what triggers each later payment, how long the client has to pay once billed, and what happens if a payment is late or disputed. Each piece is a separate decision, and together they decide how much of the job you finance.

The terms live in the contract or signed estimate. Invoices should repeat them, but an invoice can’t add terms the client never agreed to. A late fee or a deposit requirement that first appears on an invoice is hard to enforce.

Most jobs combine several terms. A residential remodel might use a deposit, payments at milestones the client can see, and a final payment at completion, each due on receipt or within a few days. A commercial job might use monthly pay applications on net 30, with retainage held until closeout. Write each one as a dollar amount or a percentage, tied to a date or an event both sides can verify.

Some terms are set or limited by law. Deposits on home improvement contracts, late fees and interest, retainage on public work, and payment deadlines under prompt payment laws all vary by state. Check the rules where the job is before you set a standard policy.

Common payment terms and when they fit

These are the terms contractors use most, roughly in the order money moves on a job.

The first three set when a payment is earned. The next three set how long the client has to pay once it’s billed. Retainage and late fees adjust the amount. Mixing up those jobs, for example writing “net 30” but never saying when an invoice can be sent, is a common source of disputes.

Why clear payment terms matter

For contractors

Payment terms shape your cash flow as much as your price does. A profitable job billed only at the end on net 60 can still leave you short on payroll. Clear terms also give you something to point to when a payment is late, and a basis for a late fee or for stopping work if the contract allows it.

For homeowners and clients

Good terms tell a client exactly what they’ll pay and when, so they can line up savings, a loan draw or a budget approval. Payments tied to visible milestones let them pay for work they can see. Terms that ask for most of the price before much work is done are a warning sign.

For subcontractors and suppliers

Subs inherit the terms above them. A general contractor’s net 30, plus retainage, plus a pay-when-paid clause can add up to a long wait. Read the payment section of a subcontract as closely as the scope.

How to set payment terms step by step

1. Check your state’s rules on deposits, late fees and retainage, and any prompt payment law that applies to the job.
2. Size the deposit to your real exposure, such as special-order materials and mobilization, within any legal cap.
3. Split the rest into payments tied to events the client can verify: rough-in inspection passed, cabinets set, substantial completion.
4. Pick how long the client has to pay each invoice: due on receipt or a short window for homeowners, net terms for businesses that need them.
5. Decide on a late fee and any early-payment discount, and write down how each is calculated.
6. Keep the final payment large enough to matter but small enough that you aren’t carrying most of your profit until the punch list is done.
7. Put it all in the contract or signed estimate, then repeat the terms and the due date on every invoice.

Once you have terms that work, make them your standard and change them only on purpose. Terms that vary from client to client are hard to track and easy to argue about.

Payment terms example for a $48,000 remodel

Say a remodeler signs a $48,000 kitchen remodel. The contract sets a $1,000 deposit and four milestone payments, each due within 5 days of the invoice, plus a late fee as allowed by state law. The deposit is kept at $1,000 so the same schedule works in a state with a cap such as California’s, which limits the down payment to 10% of the contract price or $1,000, whichever is less.

The payments add up to $1,000 + $14,000 + $16,000 + $9,000 + $8,000 = $48,000. Each milestone is something the homeowner can see, and each amount is set to follow the cost of the work before it, so the remodeler is never far ahead of or behind the money.

If an approved change order adds $2,400 for under-cabinet lighting, the remodeler either adds it to the next milestone payment or bills it on its own, and the contract total becomes $50,400. Writing that choice into the change order avoids a surprise at the end.

The same job for a property manager might instead be billed monthly on net 30 with 10% retainage. A $14,000 progress invoice would then bring in $12,600 about 30 days after it’s sent, with $1,400 held until completion. Same work, very different cash flow.

Common payment terms mistakes

• Leaving terms to the invoice instead of agreeing to them in the contract first.
• Tying payments to vague events like “halfway” instead of something both sides can verify.
• Asking for a deposit above your state’s cap, which can create legal problems even if the client agrees.
• Front-loading the schedule so early payments run well ahead of the work.
• Setting a late fee without checking your state’s limits, or never mentioning it before the work.
• Accepting a client’s net 60 and pay-when-paid terms without pricing in the wait.
• Using different terms on the contract, the estimate and the invoice.

Most payment disputes start with terms that were vague, unwritten or inconsistent. Write them once, specifically, and use the same words every time.
