E-Invoice - VNIs VN-Invoice Integrator
Integrates with VN-Invoice service to issue legal e-Invoice
At a Glance
The facts of E-Invoice - VNIs VN-Invoice Integrator, version 0.2, in one place. Published by Viindoo.
Key Features
VN-Invoice (VNIs), fully integrated with the unified E-Invoice interface:
One Unified E-Invoice Interface
VN-Invoice is configured, issued, tracked, adjusted, replaced and cancelled from the same E-Invoice menu, notebook tab and status filter as every other provider - no separate screen to learn.
Approve-and-Sign Lifecycle
A VN-Invoice-only capability: each e-invoice is signed in the same send that issues it, and any e-invoice left unsigned is signed again in one click, alone or with others.
E-Invoice Cancel-Guard
An issued e-invoice can no longer be plainly cancelled, however long ago it was issued - the system blocks the action and guides you to an adjustment or a replacement instead, keeping your books compliant.
Safe 3-Step / 1-Step Cancel
Cancelling a signed VN-Invoice runs a controlled 3-step process (error notification, sign, delete) with a mandatory reason; an unsigned invoice cancels in one step - both fully auditable.
Detailed Status Tracking
A precise VN-Invoice state and sign-state model (original, adjusted, replaced, cancelled, signed, sign error, ...) rolls up into the single, normalized E-Invoice Status filter shared across every provider.
Representation and Converted Files
Generate and store the PDF/XML representation and the converted version of every issued invoice, ready for one-click download and automatic attachment to the customer email.
Multi-Company Serials, Templates and Types
Define and manage invoice serial, template and invoice type per company and per journal, matching what you have registered with VN-Invoice and the government authority.
Customer Portal Access
Customers view, print and download the display (PDF) and XML versions of their VN-Invoice straight from the customer portal.
Sandbox Mode and Chronological Safeguards
Test safely in sandbox before going live, and let the system enforce chronological issuing order so no earlier invoice is ever skipped.
Benefits
Comply with Vietnam's e-invoice regulations end to end, including the cancel-guard that keeps a signed, issued invoice from being improperly cancelled.
Issue, sign, adjust, replace and cancel directly inside Odoo/Viindoo - no manual printing, storing or delivering of paper invoices.
The same E-Invoice tab and status filter used for every provider gives you a single, real-time view of every VN-Invoice, minimizing errors and confusion.
Effortlessly manage invoice series, templates and types across different companies and journals from one system.
Give customers instant, self-service access to their legal invoices in the format they need, through the customer portal.

Instruction video: VN-Invoice
This module plugs the VN-Invoice (VNIs) provider into the unified E-Invoice interface: once installed alongside the hub (l10n_vn_viin_edi), every VN-Invoice-issued invoice is configured, issued, tracked, adjusted, replaced and cancelled from the same E-Invoice menu, notebook tab and status filter that every other provider uses - with two capabilities that are VN-Invoice-only: the approve-and-sign lifecycle and the 3-step cancel.
1. Configure the VN-Invoice service record.
- Go to Accounting ‣ Configuration ‣ E-Invoice ‣ E-Invoice Services and open (or create) the service record for VN-Invoice.
- Fill in the connection fields on that record: the Mode (Sandbox or Production), and either Username/Password for Production or Sandbox Username/Sandbox Password for Sandbox. On the Configuration tab, Sign When Issuing, under API Version, is checked by default - leave it checked so VN-Invoice signs each e-invoice when it issues it.
2. Issue an e-invoice through VN-Invoice.
- Confirm the customer invoice, then click Send. In the Send window, keep Issue Vietnamese E-Invoice checked - it is checked automatically for an invoice routed to VN-Invoice - and click Send. This issues the e-invoice and, when by Email is also checked, emails it to the customer in the same step.
- Odoo issues the e-invoices of a serial in invoice date order. An invoice dated before an e-invoice already issued in its serial cannot be issued in that serial: keep its date and issue it in another serial registered with VN-Invoice, as Issue a forgotten invoice with its own date in the guide of the Vietnamese E-Invoice Integration module explains. E-invoices of another serial never hold it back; a parent company and its branches that share a serial are ordered together.
3. Sign the VN-Invoice (VN-Invoice-only sign lifecycle).
- Once issued, use the Sign VN-Invoice button - shown next to the other e-invoice actions on the invoice - to approve and digitally sign it. The VN-Invoice Sign State field tracks progress on the E-Invoice tab: Waiting Approve while VN-Invoice approves the e-invoice, Waiting Sign once it is approved, Signing while VN-Invoice signs it, Signed when it is signed, Sign Error when it refused the signature, and Not signed while the e-invoice has no signature yet. The representation and converted files can only be downloaded once the invoice is Signed.
- With Sign When Issuing on the e-invoice service (Configuration tab, on by default), VN-Invoice signs each e-invoice in the same send that issues it - after an online payment, from the scheduled batch Send, at the point of sale or from Send on the invoice. Paying an invoice never signs its e-invoice.
- If the signature fails, the e-invoice keeps its number and stays issued: its VN-Invoice Sign State shows Sign Error and the reason is in the chatter. Sign it again with Sign VN-Invoice. Sign and send each e-invoice no later than the next working day after its invoice date.
- If VN-Invoice does not answer a sign request (for example, the connection times out), the sign state stays at Signing, because VN-Invoice may have signed the e-invoice all the same. Run Synchronize E-Invoice Information on the invoice to read its real sign state, then sign it again with Sign VN-Invoice only if it is still not signed. The reason is in the chatter.
- To sign the issued e-invoices still unsigned, filter the customer invoice list with VN-Invoice Not Signed, select the invoices and run Actions > Sign VN-Invoice. Each one is signed; a message names those VN-Invoice did not sign. When none of the selected invoices has an e-invoice waiting for its signature, the message asks you to issue the e-invoices first, then sign them.
4. Download the representation and converted files.
- From the Documents section of the E-Invoice tab, download the PDF/XML representation and the converted file once the invoice is signed.
5. Track the status once the invoice is paid.
- After the customer invoice is reconciled, both the customer invoice and the single E-Invoice Status update automatically - Paid on the invoice, and the matching status on the VNIs system - visible through the same E-Invoice Status filter and group-by used for every provider.
6. Send the e-invoice to the customer.
- Sending the invoice by email does not replace the Odoo-generated invoice PDF: the provider's legal files join it as extra attachments - the VN-Invoice XML always, and the VN-Invoice PDF as well, unless the journal has Disable Send E-Invoice PDF by email checked, in which case only the XML is added alongside the Odoo PDF.
7. Adjust or replace instead of cancelling - and cancel safely when you still can.
- An already-issued e-invoice can no longer be simply cancelled, however long ago it was issued - clicking Request Cancel blocks the cancel action and guides you to issue an adjustment or a replacement e-invoice instead.
- For an invoice still eligible to cancel, VN-Invoice runs a 3-step cancel when the invoice is Signed (create the error notification, sign the error notification, then delete) or a single-step cancel when it is not yet signed. Cancelling a signed invoice requires a cancellation reason, filled in on the E-invoice Cancel Description field.
