If your company uses multiple payment gateway configurations for example, different Nuvei keys set up for different subsidiaries, regions, or invoice types Kolleno can automatically group invoices in the customer portal based on which payment method applies to each one.
This means your customers will only be able to select and pay invoices together if they all belong to the same payment route. Invoices from different payment routes cannot be combined into one payment.
Important: This prevents payment failures that would otherwise occur when a customer tries to pay a mixed selection of invoices that cannot be processed through a single gateway.
What does it look like for the customer?
When this feature is enabled, your customers will notice that some invoices cannot be selected at the same time as others in the portal. This is intentional it ensures every payment can be processed correctly.
Customers can still pay multiple invoices at once, as long as all selected invoices share the same payment route. A single payment will be created covering all the invoices in that selection.
Important: This feature is currently available for companies using Nuvei as their payment provider with multiple gateway keys configured.
How to request this from support
Invoice grouping is not a self-serve setting the Kolleno team enables and configures it for you. To get started, contact support and include the following:
Confirm you are using Nuvei with multiple gateway keys already set up on your account (or let us know if you need those configured first).
Describe how your invoices should be split — for example, by subsidiary, invoice reference prefix, or customer portfolio. The more detail you provide, the faster we can configure it correctly.
Confirm whether all invoices are covered — let us know if there are any invoices that do not fall into one of your defined groups, as these will need a catch-all payment route to remain payable in the portal.
Important: If this feature is enabled without all invoices being covered by a payment route, some invoices may become temporarily unpayable in the portal.
