Outgoing Invoices
Issue FA(3) invoices directly to KSeF
An invoice creator with FA(3) schema validation, offline mode support, and automatic numbering. Issue invoices, corrections, and advance invoices in seconds.
FA(3) creator
A form with live validation — you cannot send an invoice with a structural error or an invalid tax ID.
Offline mode
If KSeF is unavailable, the app issues the invoice in emergency mode and submits it automatically once the service is back.
Corrections and duplicates
Create corrective invoices for any issued invoice with automatic cross-referencing.
Automatic numbering
Define numbering templates per series and year — the system keeps the sequence consistent.
