VN-Invoice: Line Grouping Option for Flexible E-Invoice Issuing
Flexibly issue VN-Invoice e-invoices in detailed or aggregated formats to simplify your invoicing process
Key Features
Built natively on Odoo/Viindoo to streamline real business operations:
Detailed or Aggregated Issuing, Your Choice
Issue every VN-Invoice e-invoice in its original detailed form, or switch to a line-grouped (aggregated) form that buckets similar lines together - per invoice, on demand.
Bilingual, Weighted-Average Grouped Lines
Each grouped line transmitted to VN-Invoice carries a weighted-average unit price and a bilingual product / unit-of-measure name, with an English subtitle added automatically for non-Vietnamese-speaking customers.
Built-In Data-Quality Guardrails
Issuance is blocked with a clear message whenever a grouped line carries more than one tax, no tax, or a product with no unit of measure - so invalid e-invoices never reach VN-Invoice.
Detailed Mode and Refunds Stay Untouched
Detailed mode and every credit note / refund automatically keep per-line transmission, so adjustments and replacements always stay traceable to the original invoice lines.
Benefits
Long invoices with many repeated lines become a compact, easy-to-read VN-Invoice document without losing any billed value.
VN-Invoice users get the same flexible detailed-or-grouped choice already available on other e-invoice providers - one consistent workflow across your accounting team.
Invalid grouped lines are caught and explained before transmission, so accountants fix data at the source instead of chasing a rejected e-invoice.
Corrections, replacements, and credit notes always keep the original per-line detail, protecting traceability exactly where regulators and auditors look first.
The grouping option reuses the invoice fields your team already knows - there is nothing new to set up or train on.
Invoice Lines Summary tab
Pick the grouping criteria and switch the display mode directly on the customer invoice.
Grouped VN-Invoice issuance
Aggregated lines transmit with a weighted-average price and a bilingual product name.
Guarded against invalid grouped lines
A clear blocking message appears before an unsupported grouped line ever reaches VN-Invoice.

Changes log
We continuously improve this module. Recent updates from the official Viindoo repository:
- 2026-07-05 Improved Upgraded to Odoo 18.0: renamed from Vietnam Electronic Invoice Summary to VN-Invoice Line Grouping, re-pointed onto the unified E-Invoice issuing seam, and now depends on the standalone Vietnam Electronic Invoice Line Grouping bridge instead of the retired e-invoice format flow.
- 2026-07-05 Fixed Fixed a crash that masked the "missing unit of measure" warning, and a crash on invoices carrying a section/note line while in aggregated display mode.
- 2025-07-23 Fixed Could not issue a replacement e-invoice while an invoice was set to the aggregated (grouped) display mode.
Works Great With These Modules
Extend VN-Invoice Line Grouping with complementary Viindoo apps:
Vietnamese E-Invoice Integration
The provider-agnostic backbone that unifies e-invoice configuration, issuance, tracking, adjustment and replacement for every provider.
Module l10n_vn_viin_ediE-Invoice - VNIs VN-Invoice Integrator
Issue Vietnamese e-invoices through VN-Invoice (VNIs), fully integrated with the unified E-Invoice interface. Required for this module to have any effect.
Module l10n_vn_viin_accounting_vninvoiceVietnam Electronic Invoice Line Grouping

Module l10n_vn_edi_line_groupingInvoice Line Grouping
The generic engine that lets you bucket invoice lines by product, price, tax or discount - the foundation the grouped VN-Invoice option builds on.
Module viin_invoice_line_groupingWho Should Use This Module?
Built for teams issuing Vietnamese e-invoices through VN-Invoice who need more than one presentation format.

Instruction
This module is a thin companion that bridges the VN-Invoice provider (l10n_vn_viin_accounting_vninvoice) with the provider-agnostic E-invoice Line Grouping bridge (l10n_vn_edi_line_grouping). Installed alongside both, it lets a VN-Invoice (VNIs) e-invoice be issued either in its original detailed form - one e-invoice line per invoice line - or in a line-grouped (aggregated) form, where the invoice lines are bucketed together before being sent to VN-Invoice. This module adds no screens of its own - it reuses the fields and tab that the line-grouping bridge and its engine already expose on the customer invoice, and only changes what VN-Invoice actually receives once the aggregated option is chosen.
1. Install alongside the VN-Invoice provider and the line-grouping bridge.
- Go to Apps and make sure E-Invoice - VNIs VN-Invoice Integrator (l10n_vn_viin_accounting_vninvoice) and Vietnam Electronic Invoice Line Grouping (l10n_vn_edi_line_grouping) are installed, then install this module. Once installed, the aggregated-issuing option becomes active specifically for e-invoices issued through VN-Invoice.
2. Choose the grouping criteria and the display mode on the invoice.
- Open a customer invoice billed through VN-Invoice and go to the Invoice Lines Summary tab.
- Pick an Invoice Summary Line Mode - the criteria used to bucket lines together (by product or by product template, keeping or averaging the unit price, separating by tax or discount).
- Set Invoice Display Mode to Invoice Line Grouping Lines to issue the aggregated form, or leave it at Invoice Lines to keep the original detailed form.
3. Issue the e-invoice in aggregated form through VN-Invoice.
- Issue the e-invoice as usual from the unified E-Invoice interface. When Invoice Display Mode is Invoice Line Grouping Lines, VN-Invoice receives the grouped buckets instead of the raw invoice lines: each bucket carries a weighted-average unit price and a bilingual product / unit-of-measure name (Vietnamese is always shown; an English subtitle is added automatically when the customer's language is not Vietnamese).
4. Detailed mode and refunds always transmit per-line detail.
- Leaving Invoice Display Mode at Invoice Lines, or issuing a credit note / refund, always sends VN-Invoice the original per-line detail - grouping is bypassed automatically so adjustments and replacements stay traceable to the original invoice lines.
5. Fix data-quality issues flagged before an aggregated e-invoice can be issued.
- VN-Invoice requires exactly one tax and a unit of measure on every grouped line. If a bucket carries more than one tax, no tax at all, or a product with no unit of measure, issuance is blocked with a message identifying the line and product to fix before trying again.
