Import invoices to KSeF in seconds — individually or in bulk
KSeF GPT lets you upload invoices to the National e-Invoice System manually or in bulk, without errors, stress or complex configuration.
How does import work?
The process is simple: choose a mode, add files, and the system validates and sends them to KSeF.
Import a single invoice or load hundreds of documents at once — depending on your needs.
- Single import: upload one invoice and send it to KSeF in a few clicks.
- Bulk import: load hundreds or thousands of invoices at once. The system handles the rest.
Upload documents in the format you have at hand.
- KSeF XML
- PDF (automatic data extraction)
- files from accounting / ERP systems
- CSV / XLSX as data source for generating invoices
Every invoice is automatically checked before sending to KSeF.
- XML structure validation
- missing data detection
- correction suggestions
- bulk fixes with one click
The system sends documents to KSeF, monitors status and handles errors.
- send queue
- automatic retries
- KSeF number recording
- full operation history
