Overview
When using Billie (B2B Invoice) as a payment method and performing multi-captures on an order, there are temporary deviations in how invoices are sent to buyers. These deviations apply until Q3 2025 and are important to understand to ensure accurate invoice handling and buyer communication.
Key considerations
Invoice timing
Billie will issue an invoice to the buyer only once the order is fully captured or when the order expires—not after each partial capture.
Unfulfilled orders
If you know that the entire order cannot or will not be fulfilled, you should Release Order Authorization via Kustom’s API or in the Kustom Portal.
This will:
Cancel the unfulfilled remainder
Adjust the invoice accordingly
Prompt Billie to issue the invoice to the buyer
Single invoice per buyer
Regardless of how many partial captures are made, the buyer will only receive one invoice:
After full order capture
Or upon order expiration
Or when the remainder of the order is released
Merchant payouts
You as the merchant will continue to get paid per capture, just like today.
This change does not impact your payouts—only how and when the buyer receives the invoice.
Why this matters
This temporary behavior gives buyers more credit time when orders are fulfilled in multiple captures. By understanding and using the release mechanism when needed, you can avoid buyer confusion and ensure timely invoicing.
