To configure GST, e-invoicing, and e-way bills in Odoo, install the Indian localization and relevant EDI modules, complete your company’s legal and tax details, connect Odoo to the GSP and NIC portal APIs, then enable electronic invoicing or e-way bills on the journals that need them. Test in the non-production environment before enabling live submissions. The process is version-dependent: Odoo 19 documentation lists the Indian modules explicitly, while Odoo 16 and 17 documentation describes journal EDI settings and document processing.

What do GST, e-invoicing, and e-way bills do in Odoo?
GST configuration supplies the company and transaction information Odoo needs for Indian accounting and reporting. E-invoicing and e-way bills add government-facing electronic workflows: Odoo sends eligible documents through its integration, and the relevant portal validates or processes them. These are related functions, but they are not interchangeable.

The National Informatics Centre (NIC) says the IRP authenticates the invoice through GSTN, issues an identification number, and transfers invoice information to the GST and e-way-bill portals in real time. A successfully validated invoice receives a signed invoice, a unique IRN, and a QR code; a copy is shared with GST for GSTR-1 auto-population. NIC’s GST e-invoice project overview GST’s e-invoice overview pamphlet, updated 17 August 2023
In practical terms, the IRN is the registration result for the invoice, while the signed JSON and QR code provide evidence that the IRP accepted the reported data. GSTR-1 auto-population is a downstream benefit of the portal exchange; it does not remove the need to maintain accurate source records in Odoo.

An e-way bill addresses the transport of goods. GSTN says the requirement remains mandatory wherever an e-way bill is needed while transporting goods, even when an e-invoice is generated. An e-invoice therefore does not replace transport documentation. GSTN e-invoice system FAQs
What should be ready before configuring Odoo?
Gather the company’s correct legal identity and the separate credentials required for the integrations before testing. A mismatch in basic tax details can undermine later submissions, and Odoo’s setup requires more than just a GSTIN. Treat this preparation as a control point: enter the same legal information that the business uses on its GST registrations and portal accounts.
Recommended Free Tools
- Company details: legal name, full address, country, PAN, and GSTIN. Odoo states that GSTIN is necessary to generate e-invoices and e-way bills and to file GST returns.
- NIC portal access: API usernames and passwords created separately on the NIC e-Invoice and NIC E-Way Bill portals.
- GSP configuration: the service provider selection required in Odoo’s Indian Integration settings.
- Journal plan: identify which sales and purchase journals should submit e-invoices, e-way bills, or both. A journal-level decision prevents a test or internal journal from being submitted unintentionally.
- Environment decision: use testing/non-production configuration while validating the setup; enable production only when the organization is ready to submit live documents.
Keep a short setup record showing the PAN, GSTIN, selected GSP, the two portal users, the environment, and the journals enabled. This makes it easier to distinguish an accounting-data problem from an authentication or journal-configuration problem when a document does not receive an IRN.
These steps follow Odoo’s India localization guidance. Labels and module availability can vary by Odoo release, so use the documentation for your installed version rather than assuming that every menu is identical. Odoo 19 India localization
Which Indian modules should I install?
Install Indian Accounting first, then add the e-invoice and e-way-bill modules for the workflows you intend to use. Odoo 19’s India localization lists the following module names; exact names can vary between Odoo versions.
l10n_in— Indian Accounting localization.l10n_in_edi— Indian E-invoicing.l10n_in_ewaybill— Indian E-waybill.- Optional stock integration, if required for your workflow.
- Indian reporting modules, as applicable to your setup.
Indian Accounting provides the localization foundation. The EDI module adds the e-invoice exchange, while the e-waybill module handles the separate transport workflow. Stock integration is optional, so install or enable it only when your inventory process needs to participate in the document flow. Reporting modules can be selected according to the reports your company must produce.

How do I enter GST details and connect the integrations?
Complete company tax information before configuring API access. Then select the GSP in Odoo and enter the separate credentials for the two NIC services under Indian Integration. The sequence matters because credentials cannot correct an incorrect legal identity, and a correct company record does not by itself activate a journal for submission.
- Complete the company record. Open company information and enter the legal name, full address, country, PAN, and GSTIN. Check the GSTIN and PAN carefully before testing submissions. Also review the address for completeness because it is part of the company identity used by the localization.
- Open accounting settings. In Odoo, go to Accounting → Configuration → Settings. Menu wording may differ by version, but the relevant area is the Indian Integration configuration.
- Select the GSP. In the GSP field, choose BVM IT Consulting Services India Private Limited, the provider named in Odoo’s India localization instructions.
- Create NIC API users. Create API users on both the NIC e-Invoice and NIC E-Way Bill portals. These are distinct portal integrations; do not treat one set of credentials as a substitute for the other.
- Enter portal credentials in Odoo. In the Indian Integration area, enter the e-invoice username and password and the e-way-bill username and password in their corresponding fields. Check that each credential is in the matching service field.
- Enable the relevant services. Turn on Registered Under GST, E-Invoicing, and E-Way bill as appropriate to the company’s setup. Enabling a service makes its settings available; journal configuration still determines which documents are sent.
- Keep production disabled while testing. Odoo documents a non-production/testing setting as well as a production-environment control. Switch to production only when live submissions are intended. Do not use a production toggle as a substitute for a completed test of credentials, journals, and document outputs.
Odoo’s configuration instructions specify the GSP and the separate NIC API users as part of the setup. Odoo India localization settings
How do I enable e-invoicing and e-way bills on a journal?
Company-level integration settings do not by themselves determine which documents a journal submits. Open each relevant sales or purchase journal and enable its electronic data interchange (EDI) options for the services that journal should use. This is one of the most common boundaries in the setup: a working company connection can coexist with a journal that has no EDI option enabled.

- Find its electronic data interchange settings.
- Enable E-Invoice (IN) for e-invoice submission, E-Way bill (IN) for e-way-bill submission, or both when both workflows apply.
- Save the journal and repeat for each relevant journal. Review sales and purchase journals separately rather than assuming a setting on one applies to all.
- Decide whether confirmation should submit automatically or whether a user should initiate processing. Record that choice so operators know what to expect after posting an invoice.
Odoo’s version 16 and 17 documentation describes these journal options and explains that documents can be submitted automatically after confirmation or processed by a user. Odoo 17 India localization Odoo 16 India localization
| Journal submission approach | What happens | When it fits |
|---|---|---|
| Automatic after confirmation | Odoo submits the document after it is confirmed, when the journal’s EDI settings and integration are configured. | Use when the intended workflow is to submit automatically at confirmation and operators are ready to review the returned status. |
| User-triggered processing | A user runs the send/process action, or uses Process now when immediate submission is needed. | Use when a user needs to initiate processing rather than rely on automatic submission, or when a controlled review is required first. |
Choose the behavior deliberately: journal EDI settings control submission, so a correct company connection alone does not guarantee that a particular journal sends documents. The exact action labels can vary by version. Odoo 17 India localization
What is a sensible test sequence?
Use a small, controlled sequence before switching to production. First verify that the company record contains the intended PAN and GSTIN. Next verify the GSP and both NIC credentials in the non-production environment. Then confirm that the target journal has the correct EDI option, create or post a suitable document, and either let the automatic action run or select the manual processing action.
After processing, inspect the EDI status and the chatter attachment, then review the rendered PDF. The objective is not merely to see that an invoice was posted: you want to see the government identifiers and the document artifacts that an operator will rely on. Repeat the test for every journal combination you intend to use, because a sales journal’s settings do not prove that a purchase journal is configured.

Only after the test outputs are understood should the production-environment control be enabled. Keep the environment distinction visible to users; a successful non-production response is evidence that the configuration path works, not evidence that a live tax submission has occurred.
How can I tell whether Odoo successfully processed a document?
Check the EDI status and the generated evidence on the document, not just whether an invoice was confirmed. A successful response should leave identifiable government-processing details that can be reviewed in Odoo and, for an e-invoice, independently verified through NIC.
Check the Odoo document
- Inspect the EDI document status and determine whether processing is complete, pending, or requires attention.
- Look in the invoice chatter for the signed JSON attachment. The attachment is useful both for audit review and for independent verification.
- On the invoice PDF, check for the IRN, acknowledgement number and date, and QR code.
- If an e-way bill was generated, check its PDF for the e-way-bill number and validity date.
If processing should happen immediately, use Process now where available. Odoo’s documentation describes the EDI status, signed JSON, PDF details, and processing action. Odoo 17 document verification and processing Odoo 16 document verification and processing
Verify a signed invoice on NIC
- Download the signed JSON attachment from the invoice chatter.
- Open the NIC e-Invoice portal and choose Search → Verify Signed Invoice.
- Upload the JSON and submit it for verification.
This checks the signed invoice through the NIC portal rather than relying only on the copy displayed inside Odoo. It is particularly useful when a recipient or internal reviewer needs confirmation that the signed payload is valid. Odoo 19 signed-invoice verification steps

Why might an IRN, QR code, or e-way-bill number be missing?
A missing proof point means you should check the document’s processing state and configuration before treating it as successfully registered. The available evidence points to a practical sequence of checks rather than a single universal cause.
- Confirm the legal tax details. Check the company’s PAN and GSTIN, as well as its legal name and address, for accuracy. GSTIN is required for the Indian e-invoice, e-way-bill, and return workflows.
- Check integration setup. Confirm the selected GSP and that the correct API username and password were entered for each NIC portal integration. A valid e-invoice credential does not establish the e-way-bill connection.
- Check the journal. Verify that the specific sales or purchase journal has the relevant E-Invoice (IN) or E-Way bill (IN) option enabled. Company-level switches do not replace this journal setting.
- Check the EDI status and chatter. Look for the signed JSON attachment and use the available processing action if the document has not yet been sent or processed. If the status is pending, do not assume that the absence of an IRN is a permanent failure.
- Check the intended environment. Verify whether the database is configured for testing or production, and do not interpret a test setup as proof of a live submission.
- Check the expected artifact. An e-invoice should expose IRN, acknowledgement data, and QR code on its PDF; an e-way-bill PDF should expose the e-way-bill number and validity date. Looking for the wrong artifact can make a completed workflow appear incomplete.
Once e-invoice processing succeeds, the invoice PDF should expose the IRN, acknowledgement data, and QR code. An e-way-bill PDF should show its number and validity date. If the expected artifact is absent, the document has not provided the practical proof point to verify. Odoo 17 India localization Odoo 16 India localization
How do cancellation and linked e-way bills work?
Odoo’s documented cancellation flow lets a user enter a reason and remarks and request EDI cancellation. A linked e-invoice and e-way bill affect each other: Odoo warns that cancelling one also cancels the other.

- Open the relevant document and request EDI cancellation.
- Enter the cancellation reason and remarks. Use remarks that explain the operational reason so the request can be reviewed later.
- Check the cancellation status before assuming it has completed. If the cancellation is still pending and has not been processed, Odoo documents that it can be called off.
- After completion, review the linked document as well. Do not leave an e-way-bill copy in circulation on the assumption that only the invoice changed.
Take care with linked documents: an e-invoice cancellation also cancels its linked e-way bill, and cancelling the e-way bill also cancels the linked e-invoice. Review the related document before requesting cancellation. A pending request that has not been processed can be called off, so check its state before attempting a second action.

Does Odoo setup tell me whether a transaction must have an e-invoice or e-way bill?
No. Configuring Odoo enables a workflow; it does not determine whether a taxpayer, transaction, or movement of goods is legally within scope. The official Odoo material describes system operation, but it does not provide a complete, current applicability matrix for every taxpayer type and transaction.
Do not rely on a universal turnover threshold inferred from the software setup. Applicability depends on current GST notifications and the relevant taxpayer and transaction details; verify those requirements for the applicable date before deciding which documents to submit. E-way-bill obligations also continue wherever transport rules require them, regardless of e-invoicing. GSTN e-invoice system FAQs
How do Odoo 16, 17, and 19 instructions differ?
Use documentation matching your installed version, because module naming and navigation are version-specific. The available Odoo references do not provide a complete side-by-side change log, so do not infer that every setting or label is identical across releases.
| Version reference | Documented emphasis | Implementation implication |
|---|---|---|
| Odoo 19 | Explicit Indian accounting, e-invoice, and e-way-bill module list; signed-invoice verification steps. | Use the listed modules as a starting point, then follow the menus in the 19.0 database. |
| Odoo 17 | Journal EDI options, automatic or user-triggered processing, document evidence, and cancellation behavior. | Confirm journal settings and use the documented processing and cancellation actions. |
| Odoo 16 | Journal EDI options and processing, verification artifacts, and linked cancellation behavior. | Expect equivalent concepts but verify the exact labels and paths in the 16.0 interface. |
- Odoo 19: the India localization page explicitly lists the Indian accounting, e-invoice, and e-way-bill modules and includes signed-invoice verification instructions.
- Odoo 16 and 17: the referenced pages describe journal EDI options, automatic or user-triggered processing, document evidence, and linked cancellation behavior.
When a menu label differs, use the equivalent accounting configuration, journal EDI, or document-processing setting in the documentation for your release rather than copying a path from another version. Odoo 16 India localization Odoo 17 India localization Odoo 19 India localization

Operational checklist for go-live
Before live submissions, walk through the entire chain in order:
- Confirm the Indian Accounting, e-invoice, e-way-bill, optional stock, and reporting modules appropriate to the installed version.
- Review the legal name, address, country, PAN, and GSTIN in company information.
- Confirm the GSP is set to BVM IT Consulting Services India Private Limited where required by the Odoo configuration.
- Verify that separate NIC API users and passwords exist for e-invoice and e-way bill.
- Keep the environment in testing while validating credentials and document outputs.
- Enable E-Invoice (IN) and E-Way bill (IN) only on the journals that should submit those documents.
- Test automatic confirmation or the user-triggered processing path selected for each journal.
- Review EDI status, signed JSON, IRN, acknowledgement number and date, QR code, and e-way-bill number and validity date.
- Verify a signed JSON through NIC when an independent check is required.
- Switch to production only after the test evidence is understood, then monitor the first live documents using the same checklist.
This checklist separates tax-data accuracy, integration authentication, journal scope, environment, and document evidence. That separation makes troubleshooting faster and reduces the risk of assuming that one successful step proves the entire workflow.
Frequently Asked Questions
Can I use the same NIC API credentials for e-invoices and e-way bills in Odoo?
Odoo’s setup calls for API users on both the NIC e-Invoice portal and the NIC E-Way Bill portal, with each service’s credentials entered under Indian Integration. Treat them as separate integrations and enter each in its corresponding fields.
Does an e-invoice automatically replace an e-way bill?
No. GSTN says the e-way-bill requirement continues wherever it is needed for transporting goods. Whether a specific movement needs one depends on the applicable transport rules.
Can I tell from Odoo’s settings whether my business is legally required to e-invoice?
No. Settings enable the technical workflow, but the Odoo documentation cited here does not establish a complete applicability matrix or a universal threshold. Check current GST notifications for the taxpayer, transaction, and date involved.
Where should I look for proof that an e-invoice was accepted?
Inspect the EDI status, signed JSON attachment, and invoice PDF. A successfully processed e-invoice should show the IRN, acknowledgement number and date, and QR code. You can also upload the signed JSON through NIC’s Search → Verify Signed Invoice function.
Why is my e-way-bill number missing when the invoice is posted?
Posting an invoice is not the same as completing e-way-bill processing. Check that E-Way bill (IN) is enabled on that specific journal, that the NIC e-way-bill credentials are present, that the document has been processed, and that the e-way-bill PDF contains its number and validity date.
Can I cancel an e-invoice without affecting its linked e-way bill?
Odoo warns that cancelling a linked e-invoice also cancels the e-way bill, and cancelling the e-way bill also cancels the linked e-invoice. Enter the reason and remarks, review the linked document, and check the cancellation status. A pending request can be called off before it is processed.
Should I enable production before testing the journal?
No. Use the documented non-production/testing setting while checking company data, credentials, journal EDI options, and output artifacts. Enable the production control only when live submissions are intended.
Do sales and purchase journals share the same EDI setting?
Configure each relevant journal individually. Odoo’s journal-level EDI options mean that enabling E-Invoice (IN) or E-Way bill (IN) on one journal does not establish the same behavior on every other sales or purchase journal.
The Bottom Line
Set up GST identity first, connect the GSP and separate NIC credentials, then configure E-Invoice (IN) and E-Way bill (IN) on each intended journal. Test outside production, confirm EDI status and signed JSON, and look for the IRN, QR code, acknowledgement data, and e-way-bill validity before treating the workflow as complete.
