A self-billing invoice supports the self-billing procedure: the recipient of a supply issues the billing document instead of the supplier. With self-billing invoices, you settle the amounts you owe your suppliers or partners yourself — without waiting for their invoice.

Where to find self-billing invoices

To see all finalized self-billing invoices, navigate to: Billing > Documents > Self-Billing Invoices.

How self-billing invoices are created

On the platform: line items and options carry a Line item type; selecting Self-Billing produces self-billing invoices instead of invoices — see Self-billing documents.

Via Document API: if the amounts are already calculated in your own system, you submit the billing data including tax details, and instellix creates the compliant self-billing invoice.

📝
When creating self-billing invoices via line items, set the Debit/Credit indicator to Credit.
