Does Horizon213 produce invoices compliant with Algerian rules?
Horizon213 carries the mandatory identifiers — NIF, NIS, RC, article d'imposition, address and fiscal regime — on every printed document, applies 19% and 9% VAT, and numbers documents in an unbroken sequence. Your accountant remains responsible for the fiscal treatment; the software makes the required information present and consistent.
Can I issue invoices in Arabic?
Yes. The document prints in the language the person issuing it is working in — Arabic, French or English — laid out for that language.
How do I correct an invoice that has already been confirmed?
You issue a credit note against it. Nothing that has been posted is edited in place, so the customer's account and your VAT position both stay explainable months later.
Does it handle the fiscal stamp (timbre fiscal)?
Not as an automatic line today. Cash-settled documents that need it should have it added by your accounting practice as part of the settlement.
