Freelance Contract Payment Terms: Net-30, Net-60, Late Fees

What this clause means

Payment terms say when the client must pay after you invoice (or after delivery or acceptance). Labels such as net-30, net-60, or net-90 mean payment is due that many days after a defined trigger—usually the invoice date, sometimes delivery, and sometimes written acceptance.

A workable freelance agreement pairs clear rates (hourly, day rate, or fixed fee) with a deposit or milestone schedule, a simple invoicing process, and consequences if payment is late. Vague wording like “paid upon satisfaction” or “paid when the project is complete” without a deadline often leaves freelancers waiting indefinitely.

Late fees, interest, and suspension-of-work rights protect cash flow. Without them, slow payers have little contractual reason to prioritize your invoice over vendors who charge for delay. Payment terms also interact with scope and termination: if the client can cancel mid-project, you still need a path to collect for work already done.

In cross-border work, payment terms should also name currency, who pays transfer fees, and what happens if a payment processor holds funds. Those details are easy to overlook and expensive to fix after kickoff.

Think of payment terms as a cash-flow design, not a formality. A beautifully scoped project with net-90 and no deposit can still put a solo freelancer in debt to their own time.

Acceptance-based payment is not automatically unfair, but it must be paired with objective acceptance criteria, a review window, and a rule that silence equals acceptance.

Red flags to watch for

Net-60 or net-90 with no deposit on a large project—you are financing the client’s cash cycle.

Payment only after “final acceptance” with no acceptance deadline or objective criteria, so the client can stall forever.

No late fee, interest, or right to pause work for non-payment after reasonable notice.

Broad set-off rights that let the client withhold payment for minor disputes on unrelated invoices.

Invoices must go through opaque portals with no service level for approval, or payment is “pay when paid” by an end client you never contracted with.

Rates locked for long periods with no adjustment if scope expands, while payment timing stays long.

Retainer language that lets the client roll unused hours forever while delaying payment for delivered work.

What to negotiate

Ask for 30–50% upfront on fixed-fee work, or weekly/biweekly billing on hourly work. Milestone billing (kickoff / draft / final) is often easier for both sides than a single balloon invoice.

Prefer net-15 or net-30. If the client insists on longer terms, raise the fee, require a larger deposit, or add an early-payment discount so net-60 is not the default path.

Define when the clock starts: invoice date, delivery, or written acceptance within a set number of days—with silence treated as acceptance.

Add a modest late fee (for example 1–1.5% per month where lawful) and the right to suspend work after written notice if invoices stay unpaid.

Collect billing contacts, PO numbers, and preferred invoice format before you start. Missing admin details are a common cause of “lost” invoices.

For overseas clients, agree currency, FX handling, and who bears wire fees. Confirm the paying entity matches the signature block.

Put invoice disputes on a short clock: the client must raise specific objections within a set number of days or the invoice is deemed accepted.

When to get a lawyer

Get legal help if the deal is large relative to your income, spans multiple jurisdictions, or the client pushes payment-on-acceptance with broad rejection rights.

Also consult counsel before signing if you are asked to waive collection costs, agree to exclusive arbitration in a distant forum solely for unpaid invoices, or accept “pay when paid” from a prime contractor with no backup obligation.

If a client routinely pays late despite contract terms, a lawyer can help with demand letters and local collection options before you sink more unpaid time into the account.

Large enterprise MSAs sometimes bury payment terms in schedules—have counsel read the full paper stack, not only the SOW summary.
