Partial Payments
An individual invoice in PayRequest is paid in a single payment for the full amount — there’s no built-in “pay half now, half later on this invoice” option at checkout. What PayRequest does support is partial refunds on invoices that have already been paid, plus a separate installment mechanism for invoices that have gone to debt collection.If you’re looking for a way to split an unpaid invoice into monthly installments, see Payment Plans — that feature is available once an invoice is in a debt collection case.
Partial Refunds
From a paid invoice’s detail page, you can issue a refund for less than the full amount, refund it in stages, or convert part of it into a credit note. This is the core “partial payment” adjustment available on any invoice.1
Open the paid invoice
Go to the invoice detail page and click Refund Invoice.
2
Choose a refund type
3
Enter an amount and description (if applicable)
For Partial Refund or Credit Invoice, enter the amount to refund. An optional description is stored with the refund record.
4
Process the refund
PayRequest calls the Mollie refund API against the invoice’s original payment and records the result.
How the Remaining Amount Is Tracked
Every invoice tracks a remaining amount — the invoice total minus all refunds that are pending, processing, or completed. You can issue multiple partial refunds against the same invoice as long as there’s still a remaining balance above €0.01.Credit Invoice + Refund
Choosing Create Credit Invoice + Refund does two things at once: it creates a credit note (a separate invoice record with negative, proportionally-calculated line items referencing the original), and it processes a Mollie refund for the same amount. This is useful when you need a formal accounting document alongside the refund, rather than just a refund transaction.Splitting an Unpaid Invoice Into Installments
If a customer genuinely can’t pay an invoice in full, PayRequest doesn’t support partial/installment collection on a standalone invoice directly. Instead, escalate the invoice to a Debt Collection case, where you (or the customer) can set up a Payment Plan that splits the outstanding balance into 2, 3, 6, or 12 monthly installments, billed automatically via a linked subscription.Authorization Holds (Partial Capture)
A related but distinct concept: Security Deposits let you place a credit card authorization hold on a product order and later capture only part of it (e.g., charging €75 of a €500 hold for minor damage). This applies to deposit-enabled products, not to standard invoices.FAQ
Can a customer pay only part of an invoice at checkout?
Can a customer pay only part of an invoice at checkout?
No — invoices are paid in full in a single Mollie payment. If the customer needs to spread the cost, use a Debt Collection Payment Plan instead.
Can I refund an invoice more than once?
Can I refund an invoice more than once?
Yes, as long as the invoice still has a remaining (unrefunded) balance above €0.01, and each refund is for a different amount.
What happens to the invoice status after a partial refund?
What happens to the invoice status after a partial refund?
A partial refund doesn’t change the invoice’s status — it stays Paid. The refund is tracked separately and shown on the invoice’s activity timeline.
Can I refund an invoice that hasn't been paid yet?
Can I refund an invoice that hasn't been paid yet?
No. Refunds require an existing Mollie payment on the invoice — there’s nothing to refund on an unpaid invoice.
