By default, Kolleno allows payments that exceed the open balance on an invoice. This enables flexibility for scenarios like credit allocation or prepayments.
What This Means
Allowed
Payments greater than the open invoice amount overpayments are accepted.
Not Enforced by Default
Kolleno does not block users from paying more than what is due.
Want to Block Overpayments?
If your business requires strict control to prevent overpayments, you can request to block any payment that exceeds the open balance.
This configuration change must be made by the Kolleno support team.
Overpayment Request
To enable overpayment blocking, contact Kolleno Support and reference the following code:
payments_allow_to_exceed_balance
Once enabled, Kolleno will reject any invoice payment that exceeds the remaining balance.
Auto Allocation Request
If automatic payment allocation is enabled, overpayment blocking behaves differently.
When this setting is active:
• No error is shown if a higher amount is entered
• The payment amount is automatically adjusted to match the open balance
• The customer can proceed to checkout
To enable automatic payment allocation, contact Kolleno Support and reference:
