A Tunisian invoice follows precise rules: unbroken numbering, both parties' tax identification numbers, VAT split by rate, stamp duty, and withholding tax where it applies. This guide sets out what the law requires, what separates a PDF from a genuine electronic invoice, and which criteria matter when choosing software — with figures and sources.
Compliant invoicing software in Tunisia produces invoices carrying every detail required by article 18 of the VAT code — a number from an unbroken series, the tax identification number of both seller and buyer, the description and unit price excluding tax, VAT split by rate, stamp duty on a separate line, and the total including all taxes — and works out withholding tax on its own where it applies. If it also handles electronic invoicing, it generates the TEIF format, applies an electronic signature and files the document on the TTN's El Fatoora platform: a PDF sent by e-mail meets none of those three conditions. On the Tunisian market, offers range from a limited free tier to about 60 dinars excluding tax per month for a full ERP. Swifto charges 59.9 TND excl. tax/month for five users, with unlimited invoicing, stock, cash management and electronic invoicing in the same subscription.
The baseline is set by article 18 of the VAT code. A missing detail can lead to the document being rejected, your customer's VAT deduction being challenged, or payment being refused.
Figures checked on 17 August 2026 against the VAT code and the personal and corporate income tax code; they change with each annual finance act. The detail — VAT split line by line, net payable, worked examples — is set out in our article Invoicing in Tunisia: VAT, stamp duty and withholding tax. Before applying any figure to a real invoice, confirm it with your accountant.
The three words do not mean the same thing, and only one carries the evidential value the tax administration expects.
Issued, printed and archived on paper. It remains valid if it carries every mandatory detail, but everything — numbering, VAT calculation, stamp duty, archiving — rests on the diligence of whoever produces it.
This is a dematerialised paper invoice, not an electronic invoice. A scanned document or a layout exported to PDF has no structured format, no electronic signature and no filing on the national platform.
Three conditions together: the national TEIF format, structured and machine-readable; an electronic signature guaranteeing origin and integrity; and filing on the El Fatoora platform operated by the TTN, which timestamps the exchange.
The full circuit — TEIF generation, signature, server seal, filing, receipts and archiving — is described on the Electronic invoicing in Tunisia page.
The advertised price says almost nothing until you bring it back to the same scope. These five questions rule out half the candidates before the first trial.
We applied these criteria to seven Tunisian publishers, with public prices and sources: comparison of invoicing software in Tunisia.
