E-Invoice - Viettel S-Invoice Integrator
Integrates with Viettel's S-Invoice service to issue legal e-Invoice
At a Glance
The facts of E-Invoice - Viettel S-Invoice Integrator, version 1.0.5, in one place. Published by Viindoo.
Key Features
Built natively on Odoo/Viindoo to streamline real business operations:
Preview Draft Before You Issue
Open a full preview PDF of the S-Invoice before it is issued - no e-invoice number reserved, nothing sent to the tax authority yet - so you can check figures and layout with confidence.
Automatic Payment-Status Sync
Registering a payment on the invoice in Odoo automatically pushes the paid status to Viettel S-Invoice - one less manual step for your accounting team.
E-Invoice Cancel-Guard
An issued S-Invoice can no longer be plainly cancelled, however long ago it was issued - this module blocks the cancel, even through the core Request Cancel button, and redirects you to adjust or replace it instead, keeping you compliant.
Legal Disclosure on the Customer Portal
Your customer's portal invoice page shows the legal e-invoice number, secret code and a direct link to look it up on the Viettel S-Invoice lookup page - so they can verify it independently.
One Unified E-Invoice Interface
Issuance, adjustment, replacement and download run through Odoo's native Viettel integration and appear on the same E-Invoice menu, tab and status filter shared by every e-invoice provider - no separate Viettel-only screens.
S-Invoice Numbering, Reachable in One Place
Manage your Viettel S-Invoice templates and symbols from the same E-Invoice menu you use for every other e-invoice setting - no more digging through generic Invoicing configuration.
Benefits
The cancel-guard closes a real compliance gap: an issued e-invoice can never be silently cancelled and detached from the tax-authority record.
Draft preview and automatic payment-status sync remove two manual checks accountants used to run by hand.
Accountants stop switching between a Viettel-only screen and every other provider's screen - one E-Invoice menu, tab and status filter for all of them.
Buyers can independently verify their legal e-invoice number and secret code straight from the customer portal.
Issuance itself rides on Odoo core's own Viettel integration, so you benefit from upstream fixes and improvements while keeping the Viindoo conveniences on top.

Instruction
Instruction video: E-Invoice - Viettel S-Invoice Integrator
This module lets a company issue its Vietnamese e-invoices through Viettel S-Invoice. Issuance, adjustment, replacement and download now run entirely on Odoo core's native Viettel integration; this module adds only the handful of conveniences core does not provide - a draft preview before you issue, automatic payment-status sync, the legal e-invoice disclosure on the customer portal, and the cancel-guard on your issued S-Invoices - and it surfaces every one of them through the same unified E-Invoice interface used by every other provider in this cluster.
1. Select Viettel S-Invoice as your provider.
- Go to Accounting > Configuration > Settings and open the Vietnam E-Invoicing section.
- Set the Provider to Viettel S-Invoice. The Viettel connection fields (account, sandbox/ production mode, credentials) appear underneath.
2. Preview the draft before you issue (this module's own addition).
- On a not-yet-issued customer invoice routed to Viettel S-Invoice, press Preview Draft S-Invoice next to the usual Send & Print button. This opens the PDF exactly as it would look once issued, with no e-invoice number reserved and nothing sent to the tax authority yet - a safe way to check the layout and figures beforehand.
3. Issue the e-invoice through Send & Print.
- Confirm the invoice (Posted), then run Send & Print as usual. Odoo core sends the invoice to Viettel S-Invoice and reports back the e-invoice number, the legal status and the generated files - all shown together on the invoice's E-Invoice tab, alongside every other provider's fields.
- The e-invoice carries the invoice date: an invoice dated before today can still be issued, and one dated after today can be issued from that date on.
- For an individual customer, the personal identification number entered on the contact, or the passport number when there is none, is sent to Viettel S-Invoice with the e-invoice.
4. Download the generated files.
- Once issued, download the display version or the converted version of the S-Invoice directly from the invoice's E-Invoice tab.
5. Track e-invoice status across every provider.
- On the customer invoice list, use the E-Invoice Status filter and group-by to see, in one normalized view, which invoices are still to issue, issued, adjusted, replaced, cancelled or in error - Viettel S-Invoice included, side by side with any other provider you use.
6. Payment status syncs automatically (this module's own addition).
- When Payment Status Synchronization is enabled on the Viettel S-Invoice provider configuration (on by default), registering a payment on the invoice in Odoo automatically pushes the paid status to Viettel S-Invoice - no manual step needed.
7. Your customer sees the legal disclosure on the portal (this module's own addition).
- Once issued, the customer portal invoice page shows the legal e-invoice number, the secret code and a link to look it up on the Viettel S-Invoice lookup page - so your customer can verify the e-invoice independently.
8. Adjust or replace instead of cancelling an issued S-Invoice.
- An already-issued Viettel S-Invoice can no longer be simply cancelled, however long ago it was issued - this module blocks it even when you click core's own Request Cancel button. The button stays visible, but clicking it raises a message pointing you to adjust or replace the e-invoice instead, so a legitimately issued S-Invoice can never be silently detached from the tax authority record.
- To increase an issued S-Invoice (the law has an increase issued as an adjustment with positive amounts), first install the Debit Notes module from Apps if it is not installed yet. Then open the invoice and choose Actions > Debit Note. Keep Copy Lines to start from the original lines, then set the lines to the amounts added. On the debit note's E-Invoice tab, check that the Adjustment type is Money adjustment and, for a business customer, enter the written agreement in Agreement Name: Send & Print refuses the debit note of a business customer without it, as the credit note wizard does, unless the seller or the sale is exempt. Confirm it and run Send & Print: Viettel S-Invoice receives it as the increase adjustment of the original e-invoice, which then shows as adjusted. In the books it stays an ordinary customer invoice. An e-invoice that was replaced or cancelled is no longer in force: increase the replacing invoice instead.
9. Manage your S-Invoice numbering configuration from the E-Invoice menu.
- Go to the unified E-Invoice menu (Accounting > Configuration > E-Invoice) and open the SInvoice entry to reach the Viettel-specific Templates and Symbols used to number your S-Invoices - reachable from the same place as every other e-invoice setting, instead of buried under the generic Invoicing settings.
