France - TVA sur Marge
Complete Margin VAT management (Art. 297 A of the French Tax Code)
Odoo 19 module for Margin VAT management, designed for taxable resellers of second-hand goods, in compliance with Article 297 A of the French Tax Code (CGI).
Margin VAT principle
Unlike standard VAT calculated on the net selling price, Margin VAT is calculated only on the profit margin:
VAT = Margin × Rate / (100 + Rate)
Example: A phone purchased for €40 and resold for €100 (incl. tax):
Margin = €60 → VAT (20%) = 60 × 20 / 120 = €10
(instead of €16.67 with standard VAT)
Key features
▶ Automatic Margin VAT calculation
Calculation engine integrated into the Odoo 19 tax system. VAT is automatically calculated on the margin when creating invoices. Supports mixed invoices (standard VAT + Margin VAT).
▶ Serial number tracking
Each product is individually identified (IMEI, SN, registration number). The purchase price is automatically captured from the vendor bill for each serial number.
▶ Compliant PDF invoices
Customer invoices display the price including tax for Margin VAT lines, hide the VAT amount (legal requirement) and add the mandatory notice Art. 297 A of the CGI.
▶ Visual KPI Dashboard
Comprehensive dashboard with KPI cards (sales, margin, collected VAT), Chart.js graphs (bar and donut), top products and top customers. Period selector: month, quarter, year.
▶ Industry-specific support
Dedicated support for mobile phones (IMEI, grade, warranty), automotive (registration, VIN, mileage, technical inspection) and art/antiques (certificate, provenance, dimensions).
▶ Industry registers
Purchase register, IMEI register (mobile phones) and police register (used vehicles) in PDF format, compliant with regulatory requirements.
▶ Purchases & Inventory integration
The purchase price is captured when validating the vendor bill and stored on the serial number. Full traceability from purchase to sale.
▶ Pre-configured taxes
Three ready-to-use Margin VAT rates: 20%, 10% and 5.5% (sale and purchase), with dedicated tax groups.

FAQ - Frequently Asked Questions
❓ I have Odoo Enterprise, how do I install the module?
Install the France - TVA sur Marge module from the Apps menu. The Enterprise bridge module (CA3 integration) installs automatically: no additional action is required. Margin VAT amounts will appear directly in your CA3 return.
❓ I have Odoo Community, how do I report Margin VAT?
The companion module CA3 Community Report (included and free) allows you to generate a CA3 summary with PDF and Excel export from Accounting > Reports. It is compatible with third-party accounting modules (base_accounting_kit, om_account_accountant, etc.).
❓ Does the module work on Odoo Online (SaaS)?
No. Odoo Online does not allow third-party module installation. You must use Odoo.sh or an On-Premise installation.
❓ Can I mix standard VAT and Margin VAT on the same invoice?
Yes. Mixed invoices are fully supported. Each invoice line is processed according to its tax: standard VAT lines display the net price and VAT, Margin VAT lines display the price including tax with the legal notice.
❓ How is the purchase price captured?
When validating the vendor bill, the purchase price is automatically recorded on the serial number (lot). When creating the customer invoice, the lot and purchase price are auto-filled from deliveries. The purchase price is then locked to prevent any subsequent modification.
❓ Which business sectors are supported?
Three sectors with dedicated fields: Mobile phones (IMEI, grade, warranty), Automotive (registration, VIN, mileage, technical inspection) and Art/Antiques (certificate, provenance, dimensions). Each sector has its own regulatory PDF register.
❓ Is the PDF invoice compliant with the law?
Yes. In compliance with Article 297 A of the CGI: the price shown to the customer is the price including tax, the VAT amount is hidden, and the mandatory legal notice is added automatically.
