In Optix, credit appears as an invoice line item with a negative amount. If the invoice total becomes negative, it turns into a credit note, which can then be used to help pay for future invoices for the same user or team.
Note: Creating a credit note in Optix does not automatically refund a user or a team. If a user is not intending to use their credit towards a future invoice and you would like to refund them, you will need to process your refund via your payment gateway.
How is credit generated and where does it appear?
Credits can be created automatically by Optix or manually by an admin. When credit is generated in Optix, the credit line item will appear on the User’s or Team’s pending invoice.
Important: Credit is only created for paid bookings once they have been paid – not for paid bookings that are unpaid, or free bookings.
Automatic credit generation
Optix will automatically generate a credit when:
A user cancels or shortens a booking via the app
A user cancels a booking via the widget booking confirmation email link
Credit generated manually by an admin
Optix will generate a credit when:
An admin cancels or shortens a booking on behalf of a user or team and selects Create invoice credit
An admin cancels a user or team plan and opts to Create a credit invoice item for unused plan periods
How is credit applied?
Credit can be applied automatically or manually, depending on your invoice policy settings.
Automatically apply credit to new invoices
You can configure Optix to automatically apply available credit to newly finalized invoices. To do this:
Go to Settings in the left-hand menu
Under Features, select Invoicing
Click Invoice Policy
Toggle “Automatically use available credit to pay off newly finalized invoices”
Click Save Changes
Note: This setting does not affect credit applied during manual invoice finalization.
Manually apply credit
If automatic credit application is off to move a credit line item from a pending invoice to a specific upcoming/due/overdue:
Remove the credit line item from the pending invoice
Examples and edge cases
Timeline example
Imagine your invoicing policy adds charges to the next invoice:
Booked May 1 (invoiced June 1), cancelled May 15 → No credit generated (booking not yet billed)
Booked May 30, paid June 1, cancelled June 2 → Credit is generated (booking was finalized)
Want to apply allowance to a user's account rather than credit?
