Payment terms

Payment terms say how much is paid, when the clock starts, and what happens if an invoice is late.

Last updated 26 October 2026

Payment terms are the part of a contract that covers money. They usually set the fee, whether a deposit is due, when you invoice, how many days the client has to pay, and what happens if they do not. Everything else in the paper is easier to keep calm if this section is specific.

The due-date line is often written as Net 14, Net 30 or Net 60. The contract should also say whether unused hours roll over, whether expenses are extra, and which currency and bank details apply. A statement of work that lists a fee with no invoice trigger is how people invent “we thought it was on launch” in week eight.

People commonly negotiate the deposit size, the net period, milestone billing, and a pause if an invoice is overdue. A late fee is one option; a right to pause the work is another. Freelancers who cannot face a late-fee argument often get further with a pause and a larger deposit.

In the UK, statutory interest on late commercial debts is set under the Late Payment of Commercial Debts (Interest) Act 1998, and gov.uk states the rate as 8% plus the Bank of England base rate. Contracts often set their own rate instead. This page does not tell you which to use; it only notes that the sourced statutory rate exists if you want the usual wording.

Agencies that reuse a master services agreement should put the payment habit in the master and the actual numbers in each statement of work: the fee, the milestones, the deposit for that job. If the two papers disagree, the order of precedence clause is what decides which one finance follows.

A worked example

A website build is 30% on signature, 40% at design approval and 30% on launch, each invoice due Net 14 from its date. The statement of work names the client contact who may approve a milestone. If that person is silent for five working days, the milestone is accepted and the invoice can go out. Extra pages are a change order, not a free extra.

How it shows up in a contract

Sample wording · our own drafting

The Supplier will invoice the Client on signature for the Deposit and on completion of each Milestone for the sums in the Schedule. The Client will pay each undisputed invoice within [14] days of the invoice date. Interest accrues on overdue sums at the rate set out in this agreement. The Supplier may suspend work while any undisputed invoice is more than [7] days overdue.

In Plain English

The supplier invoices the deposit on signature and the rest each time a listed stage is done. The client has 14 days from the invoice date to pay, unless they dispute it. Late sums carry the interest written here. If an invoice is more than 7 days late, the supplier can stop work.

Common mistakes

  • Listing a total fee with no invoice dates, so nobody knows when money is supposed to move.
  • Setting Net 30 in the master agreement and Net 60 in the statement of work with no order of precedence.
  • Forgetting expenses, currency or bank details, then arguing about a transfer fee after delivery.
  • Having a late fee and no clear due date, so the extra charge has nothing to attach to.
