Key Features
IRN generation for customer invoices posted from Odoo — pushes the INV-01 GST JSON schema to the NIC IRP (directly or via your GSP) and writes the returned IRN, Acknowledgement Number and date onto account.move.
Government signed QR code retrieved from the IRP and embedded on the invoice PDF through an extended QWeb report template, printed in the auditor-expected position on the tax invoice.
E-Way Bill generation from the same invoice/delivery flow, capturing distance, transporter ID, transport mode and document details, with the EWB number linked back to the source document.
Part-B vehicle number and transporter update support so drivers/vehicles can be added or changed after the EWB is issued without leaving Odoo.
Auto-cancellation workflow that respects the 24-hour IRN cancellation window — an ir.cron job flags invoices nearing the deadline and authorised users cancel with an NIC reason code straight from the invoice.
GSTIN validation and format checks on customer and company partners, blocking transmission of documents with malformed or missing GST numbers via @api.constrains guards.
HSN/SAC code mapping and validation on products and invoice lines, ensuring every taxable line carries a compliant code before the payload is built.
IRP/GSP authentication and token management in a dedicated service layer, with credentials stored in configuration and readable only by privileged roles.
Sandbox and production environment switching so you can validate the full flow in NIC test mode before going live, controlled from Odoo Settings.
Readable NIC error-code handling — government rejection codes are parsed and shown as clear Odoo user messages and logged, instead of failing silently or dumping raw responses.
Status tracking on every invoice (not generated, generated, cancelled, error) with a Smart-button/stat view and filterable list views for the compliance team.
Role-based security via ir.model.access.csv and record rules — only assigned accounts/compliance users can transmit, cancel, or view e-invoice credentials and logs.
Full audit logging of every IRP/EWB request and response for reconciliation and GST audit defence.
Multi-GSTIN / multi-branch aware design so groups operating several registrations can route each invoice to the correct GSTIN and IRP profile.
Bulk/queued transmission option so a batch of posted invoices can be sent to the IRP asynchronously rather than one at a time.
About this Product
India GST E-Invoicing & E-Way Bill (IRN/NIC) is a build-to-order Odoo module that ECOSIRE designs, builds, installs, and supports for your specific GST registration and workflow — this is not a pre-packaged apps.odoo.com download you install yourself. Over a 2–4 week engagement we ship a production-ready connector that pushes your Odoo customer invoices to the NIC e-invoice system (either directly or through your chosen GSP), retrieves the Invoice Reference Number (IRN), Acknowledgement Number, and the government signed QR code, and stamps them back onto the invoice and its PDF — all inside standard Odoo accounting, with no copy-pasting into the government portal.
Why Choose India GST E-Invoicing & E-Way Bill (IRN/NIC)
IRN generation for customer invoices posted from Odoo — pushes the INV-01 GST JSON schema to the NIC IRP (directly or via your GSP) and writes the returned IRN, Acknowledgement Number and date onto account.move.
Government signed QR code retrieved from the IRP and embedded on the invoice PDF through an extended QWeb report template, printed in the auditor-expected position on the tax invoice.
E-Way Bill generation from the same invoice/delivery flow, capturing distance, transporter ID, transport mode and document details, with the EWB number linked back to the source document.
Part-B vehicle number and transporter update support so drivers/vehicles can be added or changed after the EWB is issued without leaving Odoo.
Auto-cancellation workflow that respects the 24-hour IRN cancellation window — an ir.cron job flags invoices nearing the deadline and authorised users cancel with an NIC reason code straight from the invoice.
GSTIN validation and format checks on customer and company partners, blocking transmission of documents with malformed or missing GST numbers via @api.constrains guards.
Under the hood the module extends account.move with dedicated fields (IRN, ack number, ack date, signed invoice, signed QR payload, e-invoice status) declared on a Python models.Model class, computed and guarded through @api.depends and @api.constrains so a document can only be transmitted when it is genuinely eligible. A configurable service layer handles authentication and calls to the IRP/GSP over JSON-RPC/REST, builds the GST schema (INV-01) JSON from your invoice lines, taxes, HSN/SAC codes and GSTINs, and parses the response defensively — surfacing NIC error codes as readable Odoo messages instead of raw stack traces. QWeb report templates are extended so the signed QR image and IRN print on the tax invoice exactly where auditors expect them.
For logistics, the module generates E-Way Bills from the same document flow, captures transporter and vehicle details, supports Part-B vehicle number updates, and links the EWB number back to the delivery and invoice. Automated actions and scheduled jobs (ir.cron) handle the compliance-sensitive timing — for example flagging invoices that are approaching the 24-hour IRN cancellation window and letting authorised users cancel with a reason code before it closes. Access is locked down through ir.model.access.csv plus record rules so only your accounts and compliance roles can transmit, cancel, or view credentials, and every API call is logged for audit.
ECOSIRE builds and tests the module on your target Odoo version (17, 18, or 19), against your sandbox/production NIC or GSP credentials, wires it to your existing chart of accounts and tax configuration, and hands over a working system with documentation, admin training, and a warranty support window. Because it is bespoke, we adapt it to Community or Enterprise, multi-GSTIN branch setups, custom invoice numbering, and any GSP your finance team already uses.
What you get
- The complete custom Odoo module (source code) — Python models, XML/OWL views, extended QWeb report templates, ir.model.access.csv, record rules and manifest — built for your target Odoo 17, 18 or 19.
- Installation and configuration on your Odoo instance (Community or Enterprise), wired to your existing chart of accounts, tax setup and invoice numbering.
- NIC / GSP integration setup and connectivity testing against your sandbox credentials, then cutover to production credentials once validated.
- Data configuration: GSTIN profiles, HSN/SAC mapping, transporter records and environment (sandbox/production) switches.
- Admin and user documentation covering day-to-day IRN generation, e-way bill issuance, cancellation within the 24h window, and error resolution.
- A live training session for your accounts and compliance team, with a recorded walkthrough.
- A post-go-live warranty support window for bug fixes and NIC/GSP adjustment, plus a handover of the audit log and configuration.
- Source-code ownership handover and a short technical README so your team or partner can maintain and extend the module.

Frequently Asked Questions about India GST E-Invoicing & E-Way Bill (IRN/NIC)
+How long does delivery take, and what is the process?
This is a build-to-order module with a typical lead time of 2–4 weeks from kickoff. After a short requirements call we confirm your Odoo version, GSP/NIC access, GSTIN structure and invoice formats, then build and test against your sandbox credentials, install on your instance, run a joint UAT, and cut over to production. Timelines can shorten for a standard single-GSTIN setup or extend for complex multi-branch or heavily customised accounting.
+What do I get for support and updates after go-live?
Every engagement includes a post-go-live warranty window for bug fixes and adjustments to NIC/GSP behaviour, plus documentation and training. Because the GST e-invoice and e-way bill schemas and IRP endpoints change over time, we also offer an optional ongoing maintenance plan that keeps the module aligned with NIC/government API updates and your Odoo upgrades. You receive the source code, so your own team or Odoo partner can also maintain it.
+Do I need a GSP, or can it connect to NIC directly?
Both are supported. The module's service layer can call the NIC e-invoice IRP directly or route through a GSP/ASP that your finance team already uses. During requirements we configure authentication and endpoints for your chosen path, and you keep control of your credentials — they're stored in Odoo configuration and readable only by privileged roles.
+Which Odoo versions and editions does it work with?
We build for Odoo 17, 18 and 19, on both Community and Enterprise. The module extends standard accounting (account.move) using core ORM patterns — models.Model fields, @api.depends/@api.constrains, ir.model.access.csv, record rules and QWeb report inheritance — so it fits cleanly alongside Odoo's Indian localisation and your existing tax configuration rather than forking it.
+How is the 24-hour IRN cancellation window handled?
The government allows an IRN to be cancelled within 24 hours of generation. The module tracks each invoice's IRN timestamp and uses a scheduled ir.cron job plus automated actions to flag documents approaching that deadline, letting authorised users cancel with the correct NIC reason code directly from the invoice. After the window closes, the UI reflects that cancellation is no longer permitted so your team doesn't attempt an invalid action.
+Is this an instant download from the Odoo App Store?
No. This is not a pre-built apps.odoo.com module you download and self-install. ECOSIRE designs, builds, configures and supports it specifically for your GST registration, GSP and Odoo environment. That's why it's ordered as a build-to-order engagement with a 2–4 week lead time rather than an instant download.
