Key feature
VAT on margin: finally automatic
As a professional reseller who buys from individuals, you are subject to the VAT on margin regime. This complex calculation — often poorly applied — exposes resellers to tax audits and reassessments.
Units automatically detects the applicable VAT regime for each article (margin or classic VAT), calculates the correct VAT, generates separate invoices according to the applicable regulations, and exports everything into a structured file for your accountant.
- Automatic detection of the applicable VAT regime for each article (margin vs classic VAT)
- Calculation of the VAT on the profit margin according to the applicable regulation
- Generation of separate invoices according to the applicable VAT type
- Structured export for your accountant with complete detail by operation
- VAT balance visible in the dashboard for real-time tracking
All billing modes
Individually, in bulk, or automatically from a shipment.

The direct billing allows you to edit an invoice manually for a client by selecting the products concerned. Ideal for occasional sales, it offers complete customization.
For large volumes, the billing via import allows you to create several invoices simultaneously by importing a file containing the product and client information. Units automatically generates all documents.
The billing from a shipment automatically converts a shipped order into an invoice. Once the shipment is validated, Units automatically fills in all the necessary information.
"The billing module is very good and allows us to have a good follow-up as well as significantly reducing our billing errors. Before Units, we used Excel files that could contain thousands of lines."
