Not every customer can clear a large invoice in one go. Part payments record what landed and leave the rest open.
From the portal (Growth+)
- Customer opens the payment link and chooses Pay part of it.
- They enter an amount, or use quick chips (showcase shows 25% / 50% / 75% of the due amount).
- The page states how much would remain on the invoice after that amount.
- They confirm (wording reflects the amount they chose).
If card is not enabled, the flow still captures intent and points them to pay you with the invoice reference so you can match the money.
From your side (all plans)
- Open the invoice.
- Choose Mark paid / Record payment.
- Enter the amount that actually arrived (less than the full balance), the date, and an optional note.
- Save. The invoice should show the residual as still outstanding (often as a part-paid style state in the register).
What happens to chasing
Safety rules are designed so a recorded payment stops or pauses automated pressure on that invoice. Exact residual behaviour can depend on whether the balance is fully cleared; if anything still looks scheduled after a part payment, check Activity and the invoice timeline, and pause manually if you need a hard stop while you reconcile.
Part pay vs a payment plan
A part payment is a single receipt against the invoice. A payment plan (arrangements) is a schedule of instalments you and the customer agree — see Payment plans. Use plans when the rest will arrive over several dates; use part pay when money already moved once.
