# Clients can pay the rest of a partly paid invoice themselves

When part of an invoice is already paid, for example a deposit or a bank transfer you recorded, your client can now pay what is left themselves. The invoice shows the remaining balance, and **Pay remaining balance** charges exactly that amount to the card they have saved, on the web client portal and in the Consumer and branded apps. Once it goes through, the invoice is marked paid.

- **The amount is always the balance still owed.** The platform checks the balance again at the moment it charges. If it changed since the client opened the page, for example because you recorded another payment, nothing is charged and the client sees the new amount first.
- **The invoice page, the invoice document and the invoice and reminder emails** show the remaining balance and a **Pay remaining balance** button that takes the client to their account. The invoice's payment link is only offered while nothing has been paid, because it always charges the full total.
- **Pay now only appears when your venue takes card payments online.** If card payments are not set up, clients still see what they owe, and your team collects it as before. The same rule applies on the web invoices page, in the apps and on the Payment needed banner.
- **Invoices without a client account**, such as private-event invoices sent to an organiser's email, have no account to pay from. Their remaining balance is still collected by your team, as before.
- **Your changes and a client's card payment never cross.** If you record a payment, mark an invoice paid, cancel it or issue a credit note while a client's card payment for that invoice is going through, you see "Another payment or change for this invoice is in progress". Try again a minute later. Any unfinished card payment for the old amount is cancelled, so the client is never charged twice.
- **A payment link paid after the invoice was already settled, cancelled or credited is never applied.** You get an alert in the Command Center to apply or refund that payment. Cancelling an invoice or issuing a full credit note now also switches off its payment link.

A payment made this way is recorded exactly like any other online invoice payment: a payment entry, the updated balance, course-installment and private-event bookkeeping, and the usual payment confirmation email.
