Offering Early-Payment Discounts

How the discount works

An early-payment discount offers the customer a small reduction if they pay before a set date — for example, '2% off if paid within 7 days, otherwise full amount by 30 days'. The aim is to pull cash forward and reduce the number of invoices that drift past due. You are effectively paying a little to be paid sooner and more reliably.

It works best where you have a real cash-flow benefit from speed, or where chasing is consuming time you would rather spend elsewhere. The discount turns collection from a chore you do later into an incentive the customer acts on themselves — provided the saving is meaningful to them and trivial to claim.

Does the maths work?

A discount is only worthwhile if what you give up is less than what early cash is worth to you. Compare the discount against your cost of funds and the practical cost of chasing. If a 2% discount frees up cash you would otherwise borrow against, or saves hours of dunning, it can be a sound trade. If your customers generally pay on time anyway, you may simply be discounting payments you would have received regardless.

Model it before you offer it. Run realistic scenarios — how many customers take it up, how much sooner they pay — rather than assuming the best case. The late-payment calculator can help you frame the cost of slow payment so the discount is judged against a real number, not a hunch.

Phrasing the offer

Ambiguity is the enemy here. State the percentage, the qualifying date and the full amount payable if the discount is missed, all on the invoice itself: '$980 if paid by 7 March; $1,000 if paid by 30 March'. Tie the discount to the date funds are received, not posted, so a payment that arrives late does not arrive discounted.

Be clear that the discount is conditional and one-off, not a new standing price. Customers who take the discount but pay slowly should not keep it — and saying so up front saves an awkward conversation later. The cleaner the wording, the fewer disputes about whether the reduced amount was validly claimed.

GST, part-payments and edge cases

Discounts interact with GST and your records, so decide your approach before offering one. Where the final price is reduced because the customer paid early, your accounting needs to reflect the amount actually received and the GST on it — this is exactly the kind of detail your accountant should confirm for your circumstances. Document how you will handle it so your ledger stays clean.

Set rules for the awkward cases too. What happens if the customer part-pays by the date? If they pay the discounted figure a day late? Generally the cleanest rule is: discount applies only to payment in full, received by the date. Spelling that out removes the grey area a slow payer would otherwise exploit.
