What the integration covers
- Sales invoices: documents issued in the shop reach wFirma after order confirmation.
- No intermediate files: data flows directly — no export or manual import.
- KSeF: submission to Poland’s national e-invoicing system happens on wFirma’s side when routing points to the vendor.
- Status in the shop admin: you can see that the invoice reached the accounting system.
How it works in practice
The shop issues an invoice after the order, wFirma receives the full dataset, and you do not retype line items by hand. KSeF — where applicable — is handled by wFirma on its side.
The integration uses the same module model as KSeF or Subiekt 123: you enable it in the admin panel and the platform core stays untouched.
