Issue a compliant invoice (VAT and tax stamp)

Autoria computes the taxes required by Tunisian law on your quotes and invoices: VAT, tax stamp and the 2026 finance act daily levy on every rental day.

The daily levy

Article 20 of the 2026 finance act introduces a levy of 2 DT per rental day and per vehicle, included in the VAT base. Your agency owes it to the Treasury: it declares and pays it every month, on the same schedule as VAT, whether the levy was added to the rental price or included in it. The Ministry of Finance states that it is borne by the customer.

Autoria adds it to your quotes, contracts and invoices on a separate line: its legal label, the number of days × the amount per day, and its legal basis. A day whose rent is waived keeps its levy: this is the case with Ne pas facturer le jour de dépassement (geste commercial) (do not bill the overrun day, commercial gesture) on the reservation, or when you waive the rent of late days at settlement.

Check your invoicing settings

Open Paramètres (settings), Facturation tab:

• Taux de TVA: the applicable VAT rates, set by your country's legislation;
• Timbre fiscal: whether the tax stamp is applied, and its amount;
• Prélèvements journaliers (daily levies): the per-rental-day levies required by your country's legislation, with their amount per day, effective date and legal basis. The Prélèvements journaliers inclus dans le prix/jour des véhicules (daily levies included in vehicle daily prices) box tells whether your daily prices already include them (see below), and the Exporter l'état (export the statement) button prepares your monthly declaration (see below);
• Arrondi des montants (amount rounding): turns rounding of the amount due on or off (see below). Only a manager or an administrator can change this setting.

Also make sure your agency's tax ID (matricule fiscal) is filled in the Agence tab: it is printed on your invoices.

Invoice a rental

1. Open the reservation and use the Facturer action (or Voir la facturation for the reservation's invoicing tab).
2. The invoice includes the rental price, the accessories included at pickup, VAT, the daily levy and the tax stamp. Each accessory has its own line (price per day × billed days) and is subject to the same VAT as the rental. The amount excluding tax ("Total HT" on the PDF, Sous-total HT (subtotal excl. tax) in the reservation's billing tab) adds up the rental and the accessories; the discount only applies to the rental.
3. Download the PDF or send the invoice by email to the customer.

While the rental is ongoing, a banner reminds you that the amount will be finalised when the vehicle is returned.

Late return

If the vehicle is returned after the scheduled date, beyond a 59-minute grace period, every started late day is added at settlement at the vehicle rate, with its daily levy. Accessories included at pickup are also billed for these days. On the invoice, these lines are marked (retard) (late).

At the Régler le paiement (settle payment) step, the Offrir le loyer des jours de retard (waive the rent of late days) box lets you not bill their rent: the daily levy of these days is still due. The suggested amount takes this choice into account.

Rounding of the amount due

The customer's total amount due (including tax) is rounded to the nearest dinar (from 0.500 DT up, it goes to the next dinar). The pre-tax amount and VAT are recomputed to the millime from that total, and the difference shows on the Arrondi (HT) (rounding, pre-tax) line of the quote and invoice. Other amounts (deposit, maintenance costs, estimated incident cost) keep their millimes.

This rounding is on by default. To invoice the exact total to the millime, untick Arrondi activé (rounding enabled) in Paramètres (settings), Facturation tab, Arrondi des montants block. The change applies to amounts computed afterwards: quotes and invoices already issued are not modified.

Daily prices including the daily levy

By default, the daily levy is added on top of the vehicle daily price. If your daily prices already include it, tick Prélèvements journaliers inclus dans le prix/jour des véhicules (daily levies included in vehicle daily prices) in Paramètres (settings), Facturation tab, Prélèvements journaliers block. Only a manager or an administrator can change this setting.

The rental is then invoiced at the daily price minus the levy, which keeps its own line on the quote and the invoice. For example, for a vehicle at 120 DT/day before tax and a 2 DT/day levy, the rental is invoiced at 118 DT/day and the levy at 2 DT/day. VAT applies to both the rental and the levy, as without the option.

This setting is the default for every new reservation. At the Récapitulatif (summary) step, the Prélèvement journalier inclus dans le prix/jour (daily levy included in the daily price) box lets you make a different choice for that reservation, and the price breakdown updates. When the levy is included, the daily price must be at least the daily levy. Existing reservations are not modified.

Collect and send reminders

• Encaisser (collect): record a payment (cash, card, transfer, cheque…) from the reservation's invoicing. You can change the due date of a remaining balance. Both actions only appear while an amount is still due.
• Relancer (remind): from the Facturation page, send a reminder email for an overdue invoice, or for several selected invoices.
• Reservations awaiting settlement: a returned reservation that hasn't been settled yet has no invoice yet (it is issued on Régler, settle). It still shows on the Facturation page, with the À régler (awaiting settlement) status (« À régler depuis N j », awaiting settlement for N days) and Non facturée (not invoiced). Its amount is an estimate: accessories added at pick-up, late days and the tax stamp are only fixed at settlement. The Régler action opens the payment directly, with the exact amount computed by Autoria.
• The indicators at the top of the page track the total invoiced, paid invoices, overdue amounts, reservations awaiting settlement and bad payers.

Correct an issued invoice

An issued invoice cannot be edited: from the reservation's invoicing tab, choose Générer un avoir (generate a credit note), enter the amount and reason, then issue a new invoice if needed.

A credit note that cancels the whole invoice also cancels its daily levy, which shows on the credit note. A partial credit note reduces the rental without touching the levy, which is due for every rental day.

Declare the levy every month

In Paramètres (settings), Facturation tab, Prélèvements journaliers block, the Exporter l'état (export the statement) button downloads a CSV file for the chosen period (the previous month by default): every invoice and credit note issued over the period, with the reservation, registration number, customer, number of days, amount per day and levy amount. Credit notes are negative, and the net total is the amount to declare. The period is based on the documents' issue date.
