Payment terms, explained

What Net 30 actually means, which terms to offer, and why a date beats a period every time.

Last updated 25 July 2026

Payment terms are the shortest thing on an invoice and the most frequently misread. Half the late payments in small business are not decisions. They are two people counting from different days.

What the common ones mean

TermUsually meansSuits
Due on receiptRealistically within a weekSmall jobs, new customers, domestic work
Net 7Seven days from the invoice dateTrades, quick-turnaround work
Net 14Fourteen daysFreelancers, small business to business
Net 30Thirty daysThe business to business default
Net 60Sixty daysLarge organisations, often non-negotiable
EOMEnd of the month the invoice falls inSuppliers billing many small orders
30 days EOMThirty days after the month endsEffectively up to sixty days

That last row catches people out. “30 days EOM” on an invoice dated 2 August is not due until the end of September.

Thirty days from what?

This is the ambiguity that causes the arguments. Invoice date, receipt date, delivery date, or the date their accounts system logged it?

You can specify it, and most people do not. Or you can sidestep the whole question.

Write the date

Payment terms    Net 30
Due              19 September 2026

Keep the terms line if your customer expects it, and let the date do the work. Due 19 September 2026 cannot be counted differently by two people.

This one change probably shortens more payment cycles than anything else on this page. How to make an invoice covers where it goes on the sheet.

Match the terms to the customer

Offering Net 30 to a domestic customer who would have paid on the day is giving away a month of cash for nothing.

Offering Net 7 to a large organisation whose payment run is monthly does not speed anything up. It just means your invoice is overdue in their system from week two, which helps nobody.

Ask new business customers when their payment run is. It is a normal question and the answer changes what terms are worth setting.

Price for long terms

If a customer requires sixty days and the work is worth having, take it, but understand what you have agreed: you are financing them for two months.

That is a legitimate cost. Build it into the price rather than absorbing it and resenting it.

Late payment clauses

Most small businesses write one and never invoke it. That is a reasonable position, since the clause exists to be pointed at rather than collected.

If you do intend to charge, state a figure rather than a vague threat, and apply it consistently. A fee charged to one customer and waived for another is a fee you cannot defend.

What works better than penalties is being easy to pay and asking early. Getting paid on time covers what actually shortens the gap.

Deposits change the calculation

If getting paid quickly matters more than the headline terms, ask for money up front instead of shortening the tail. A third on acceptance does more for cash flow than moving Net 30 to Net 14.

Deposits and staged payments covers how much to ask and how to document it.

Put the terms in your template

They belong in the file you reopen each time, not in your head. Terms typed fresh each month are terms that drift.

Fix them once and leave the due date blank, since that changes per invoice. A free invoice template you can edit covers what else belongs in the template.

Terms are only half of it

A short payment term with no bank details on the document is slower than a long one with everything the payer needs. The constraint is rarely the customer’s willingness.

Check that the invoice carries:

What goes on an invoice covers the rest of the fields.

Discounts for early payment

Sometimes written as 2/10 net 30, meaning two per cent off if paid within ten days, otherwise the full amount at thirty.

It works, and it is expensive. Two per cent for twenty days is a high annual rate, so offer it only when the cash matters more than the margin, and never as a default.

The version to avoid is an early payment discount taken by a customer who then pays on day twenty-five anyway. Say plainly that the discount lapses.

Terms on the quote, not just the invoice

Payment terms introduced at invoice stage are terms the customer never agreed to. If they were on the accepted quote, they are part of the deal.

This matters most for deposits, late fees and anything unusual about your terms. How to write a quote covers where they sit on the sheet.

Different terms for different customers is fine

There is no obligation to offer everyone the same. New customers on shorter terms, established ones on longer, large organisations on whatever their process requires.

What causes trouble is being inconsistent without deciding to be. Write down which customers get which, so a term is a policy rather than a mood.

One line, done properly

Open the invoice maker, set your standard terms in the notes, and make the due date a real date every time. It costs nothing and it removes the most common reason an invoice waits.
