About Quittus — Compliant Invoices

Invoicing is the task no one wants and everyone must do. Quittus removes it entirely: every paid order becomes a compliant invoice, every refund becomes the matching credit note, numbered sequentially as the law requires. You enter your legal details once and stop thinking about it. Invoices carry your logo, handle multiple VAT rates, and embed Factur-X data. At month end, hand your accountant one file instead of a folder — and face an audit knowing your numbering has no gaps.
