Sale invoice examples

This page provides ready-to-use sales invoice payloads for common OMN scenarios. All examples target POST /api/sales-invoices/{supplier_profile_id} and can be adapted to your profile and business data.

How to use these examples

• Replace identifiers (profile_id, company_id, document_number etc) with your own values.

• Ensure all party tax data and tax categories are valid for your VAT treatment.

• Start with the minimal example, then extend with optional fields as needed.

Example 1: Minimal sales invoice

Use this when you need the smallest valid payload for a normal OMN standard tax invoice. See the Minimal Sales Invoice invoice example in the right-side code samples panel.

Example 2: Sales invoice with document level charges and allowances

Use this when you need document-level charges and discounts. See the Sales invoice with document-level charges + allowances example in the right-side code samples panel.

Example 3: Sales invoice with line level charges and allowances

Use this when you need line-level charges and discounts while still applying document level charges or discounts. See the Sales invoice with line-level charges + allowances example in the right-side code samples panel.

Recommended progression

1. Validate with Example 1 in sandbox.

2. Add document-level adjustments using Example 2.

3. Use Example 3 when your adjustments are applied at line level.
