Payment terms explained

Payment terms are the part of the invoice that says when the money is due and what happens if it is not. They are usually two sentences long, they are the difference between being paid in a week and being paid in a quarter, and most people copy them from whatever invoice they saw last without knowing what they committed to.

The vocabulary

These are the terms clients expect to see, and what each one means in practice.

• Due on receipt. Payable as soon as it arrives. Honest about your intent, but larger companies simply cannot process it that way, so it often gets treated as Net 30 anyway. Best used with small clients and consumers.
• Net 7, Net 14, Net 30, Net 60. Payable in full that many days after the invoice date. Net 30 is the default across most of business-to-business work. Net 60 is common with large organisations and is worth pushing back on if it does not suit your cash flow.
• Net 30 EOM, or end of month. Thirty days from the end of the month the invoice was issued in, which means an invoice sent on the 2nd is effectively on 58 day terms. Read this one carefully before agreeing to it.
• 2/10 net 30. A 2% discount if the invoice is paid within 10 days, otherwise the full amount within 30. It works surprisingly well on clients with a finance department, because someone there is measured on capturing those discounts. Do the arithmetic first: giving up 2% to be paid 20 days sooner is expensive money if you did not need it.
• 50% up front, balance on delivery. Not a standard term so much as a payment schedule, and the single most effective protection for a small supplier taking on a new client.
• Milestone billing. Payment tied to defined stages rather than dates. Suits long projects, and each milestone should be something the client can look at and agree is finished.

Choosing a term

The correct term is the shortest one the client will actually honour, and it depends on more than preference.

• Match your own outgoings. If you pay subcontractors on Net 14 and get paid on Net 60, you are financing your client for six weeks out of your own account.
• Expect large clients to have a fixed policy. A finance department running a payment run twice a month is not going to change its cycle for one supplier. What you can often negotiate instead is a deposit, or milestone invoices so the wait applies to smaller amounts.
• Price the wait. If a client insists on long terms, that is a cost of doing business with them, and it is legitimate to reflect it in the rate rather than absorb it silently.
• Agree it before you start. A term that first appears on the invoice is a proposal. A term that was in the quote or contract is an agreement. This is the whole reason the document you send before the work matters.

Deposits and the balance

A deposit invoice is a normal invoice for part of an agreed total. The part people get wrong is the second invoice, where the deposit has to be visibly deducted so the client is not asked to pay the full amount twice.

For a $4,000 project with a 50% deposit, the first invoice is for $2,000 and says what it is for. When the work is done, the final invoice shows the full value of the work, then the deposit already paid as a separate deducted line, then the remaining balance:

Referencing the earlier invoice number on the deduction line matters more than it looks. It lets the client’s bookkeeper reconcile both documents without asking you, and it means your own records show the full project value rather than two unexplained halves. If sales tax applies, it is normally charged on the deposit when the deposit is invoiced, so check how your jurisdiction wants that handled rather than assuming.

In this tool, enter the deposit in Amount already paid. The PDF shows it under Total, followed by the balance due. Put the deposit invoice number and date in the notes so the reader can match the two.

Late fees, honestly

Late payment charges are commonly misunderstood. A few things are true almost everywhere.

• It has to be agreed in advance. A late fee that appears for the first time on an overdue reminder is usually unenforceable and always damages the relationship. Put it in the quote or contract, then restate it on every invoice.
• Rates and enforceability vary by jurisdiction. Some places cap what you can charge, some give you a statutory right to interest and a fixed recovery cost on late commercial payments whether or not your contract mentions it. This is worth ten minutes of reading about your own country, once.
• Keep it simple. A flat monthly percentage on the overdue balance is easy to explain and easy to calculate. Compounding daily interest on a $900 invoice is not worth the argument.
• Its real value is deterrent, not revenue. Most people who use late fees successfully never collect one. The clause exists so that the polite reminder has something behind it.

Wording you can paste into the notes field

Plain, specific, and short. Each of these assumes the corresponding term was agreed beforehand.

Standard Net 30

Payment due within 30 days of the invoice date, by 9 October 2026. Bank transfer to Pine Studio, account 12345678, sort code 04-00-04. Please quote INV-1042 as the payment reference.

With an agreed late fee

Payment due by 9 October 2026 as agreed in our proposal dated 12 September. Overdue balances carry interest at 2% per month from the due date.

Deposit invoice

This is the 50% deposit for the brand identity project, total $4,000. Work begins on receipt. The balance of $2,000 will be invoiced on delivery.

Early payment discount

2/10 net 30: deduct 2% ($56.88) if paid on or before 19 September 2026. Otherwise the full $2,844.00 is due by 9 October 2026.

Note that the last one does the arithmetic for the client. Two percent of $2,844 is $56.88, and spelling that out removes the only friction between the client and paying you early.

Currency and cross-border payments

If you and your client are in different countries, say which currency the invoice is payable in, in words, not just with a symbol. A dollar sign is ambiguous across at least a dozen currencies, so write “All amounts in USD” in the notes.

Also state who absorbs the transfer fees. An international transfer can arrive short by $15 to $40 because intermediary banks took a cut, and if the invoice says nothing, you will end up chasing a shortfall that neither side thinks is their fault. One line settles it: “Please send the full invoice amount; any transfer or intermediary fees are payable by the sender.” Offering an account in the client’s own currency, where that is practical, avoids the problem entirely.

Put the term in two places

Finally, the mechanical bit that gets skipped. The term belongs in the notes as a sentence, and the resulting date belongs in the due date field as a date. “Net 30” on its own asks the reader to work out both the arithmetic and the starting point, and an approvals queue is not going to do that in your favour. Getting invoices paid on time picks up from there.
