How to Write Payment Terms That Actually Work

How to Write Payment Terms That Actually Work

Your payment terms are a contract. But most small businesses write them in ways that are easy to ignore, difficult to enforce, or simply too vague to be useful.

Clear payment terms protect your cashflow, reduce the need to chase invoices, and set professional expectations from the start of any client relationship.

Be Specific With Due Dates

The most important change you can make is replacing "Net 30" with an actual date.

"Payment due within 30 days" is open to interpretation. "Payment due by 15 April 2025" is not.

When you include a specific due date on your invoice, it removes any ambiguity about when payment is expected. It also makes overdue follow-up straightforward, the date passed, the invoice is overdue.

Shorten Your Terms Where You Can

If you have always offered Net 30, consider whether Net 14 or Net 21 would work just as well. Many clients will accept shorter terms without pushback, they were never asked.

For smaller jobs or new clients, Net 7 or even immediate payment is entirely reasonable. The key is to set expectations before work starts, not after.

Include Late Payment Language

Adding a late payment fee, typically 1.5-2% per month, to your terms gives you a legitimate mechanism for recovering some of the cost of late payment. It also signals that you take payment seriously.

In practice, you do not need to enforce it every time. But having it in your terms changes the dynamic. Clients know there is a consequence to delay.

In Australia and New Zealand, you can also reference statutory interest provisions in commercial contracts. Check with your accountant or legal adviser on how to word this.

State Your Payment Methods Clearly

Tell clients exactly how to pay you. Include your bank account name, BSB, and account number (or IBAN/SWIFT for international). If you accept credit cards or payment portals, include that information too.

Never assume a client knows how to pay you. Make it as easy as possible.

Get Agreement Before the Work Starts

Payment terms buried in small print at the bottom of an invoice are easy to miss and hard to enforce. The most effective terms are agreed upfront, in a proposal, a contract, or a scope of work document.

When a client signs a proposal that includes your payment terms, they have actively agreed to them. That changes the conversation if they are later slow to pay.

What to Do When Terms Are Not Enough

Even perfect payment terms cannot force a client to pay on time if they have their own cashflow challenges or simply prioritise other suppliers.
