Pay invoices with Mollie
Add a payment link to your invoice email and record a confirmed payment as a receipt.
Under Invoices you can connect Mollie using the administration’s own API key. Customers pay through a link in the invoice email. Once Mollie confirms payment, a receipt is posted to the selected Mollie account, reducing the outstanding invoice amount.
Step by step
- 1Open Mollie settings and select your existing Mollie account. If it does not exist yet, select Create a new Mollie account. Check the name, currency, ledger account number and start date; you can change the suggestions. Saving creates and connects the account. You will also find it under Bank.
- 2Open Invoices and choose Mollie settings. Enter your own API key, select the Mollie account and enable payment links. Leaving the key field empty when editing retains the existing key.
- 3Open a finalized invoice and choose Send. Select Add payment link if you want to include it. The link uses the current outstanding invoice amount.
- 4The customer opens the link and chooses Pay with Mollie. Viewing the page alone creates no payment. A confirmed payment is posted once, even if Mollie repeats its notification.
- 5If a payment has definitively been canceled, failed or expired, the customer can choose Pay with Mollie again. Once Mollie confirms that status, a new payment starts for the current outstanding amount. A payment that is still being processed is not replaced.
- 6An open payment uses the same checkout page. If it is unavailable, we first try to end the previous payment with Mollie, if Mollie allows this. A new payment starts only once that closure is confirmed. Otherwise the customer can try again later.
- 7Check the payment status in Mollie settings. Choose Check if a notification is missing. If creation is uncertain, first find the payment in Mollie and enter its Mollie payment ID there; do not blindly create another payment.
- 8Record a later Mollie payout to your bank as a transfer. Record withheld Mollie fees separately. This is not a second customer receipt against the same invoice.

- Add payment link: a choice for each invoice email
What happens next?
A confirmed payment reduces the outstanding amount through an ordinary receipt. A test key creates recognizable test receipts in this administration, so use a test administration. If Received, processing required appears, check the message, for example a closed fiscal year or a missing currency conversion. Confirmed payments awaiting posting get no new payment requests or reminders. Refunds and chargebacks are shown for review. A deliberately deleted receipt is never reposted automatically. Disabling stops new payments; existing payments remain checkable.
