Get Paid Faster with Online Invoice Payments¶
Collecting customer payments efficiently is essential for maintaining healthy cash flow. Traditional payment methods often require customers to manually transfer funds, enter invoice references correctly, and notify the supplier once payment has been made. These additional steps can lead to delayed payments, administrative overhead, and increased follow-up efforts.
CURQ simplifies the payment process by allowing customers to pay invoices directly online through the Customer Portal. By integrating with trusted payment providers such as Mollie, customers can securely settle outstanding invoices using their preferred payment method. Once a payment is completed, CURQ automatically updates the invoice status and records the payment in the accounting system.
This functionality helps organizations reduce manual administration, improve payment collection, and provide a better customer experience.
Enable Online Invoice Payments¶
To activate online invoice payments, navigate to:
Accounting → Configuration → Settings → Customer Payments
Enable the Pay Invoices Online option and click Save.

Once enabled, customers will be able to access and pay invoices directly from the customer portal.
Payment Providers¶
CURQ supports multiple online payment providers. One of the most commonly used integrations is Mollie, which allows customers to pay invoices using payment methods such as:
iDEAL
