Kolleno currently supports refunds on full individual payments only. Partial refunds are not supported.
This means:
If a $100 invoice was partially paid with $25, the refund can only be issued for the full $25 payment — not a portion of it.
If a $100 invoice was paid in full, the refund can only be issued for the full $100 — you cannot refund a partial amount of that payment.
Each refund must match the exact amount of an individual payment transaction. If you need to refund less than the full amount of a payment, this is not currently possible directly from Kolleno.
Steps
You can issue a refund quickly via Kolleno. If the payment was taken on the Kolleno payment portal. Click into your customer from your customer list.
Click the Kolleno Payments tab and find the desired payment(s) to refund.
On the right hand side of the payment click the three dots and choose "create refund".
You will then need to click the blue "Create Refund" button to action this.
