Invoice Number on Every POS Receipt — Automatically
Display the invoice, boleta, or fiscal document number the moment the receipt prints.
Zero configuration. Works with every Odoo localization.
The Problem
Standard Odoo POS
- Invoice is created after the receipt prints
- No invoice number on the printed receipt
- Fiscal compliance issues in LATAM & other regions
- Manual workarounds needed
With This Module
- Invoice number fetched automatically before receipt renders
- Displayed prominently on the printed receipt
- Fiscal compliance for Peru, Chile, Argentina, Colombia, Mexico …
- Zero manual steps — just install and go
Key Features
Automatic Fetch
Dedicated JSON-RPC endpoint retrieves the invoice number reliably — works in both online and offline-sync POS modes.
Before First Paint
OWL reactive state with onWillStart ensures the invoice number is ready before the receipt renders. No flicker.
Native Receipt
Works with the standard Odoo 18 POS receipt out of the box. No extra configuration needed.
Receipt Builder Ready
Fully compatible with POS Receipt Designer. Use the {{invoice_number}} placeholder in any custom template.
Receipt Templates Ready
Works seamlessly with POS Receipt Templates — 10 professional designs that can now include the invoice number.
Third-Party Compatible
export_for_printing is patched to include invoice_number, so any module reading receipt data can access it.
How It Works
Order & Invoice
Cashier completes a sale in POS. Odoo creates the invoice (manually or via auto-invoice).
Automatic Fetch
Before the receipt renders, the module calls the backend to get the invoice number (e.g. B E01-00000001).
Print with Number
The invoice number appears prominently on the printed receipt. Done — no extra clicks needed.
Step 1: Check “Invoice” on the Payment Screen
Enable the Invoice checkbox before validating the payment
Step 2: Invoice Number Appears on the Receipt
The invoice number is fetched automatically and displayed right after “Served by”
