Poland uses a clearance model with a centralized exchange through government platform that supports various document types and business scenarios covered by the FA(3) schema.
Business process model
The model follows this path: Supplier → Sovos → Krajowy System e-Faktur (KSeF) → Buyer.
-
The supplier submits invoice to KSeF for clearance (through Sovos).
-
Sovos validates every document before submission to KSeF to catch structural errors, including missing required fields, wrong data types, invalid enumerations, and malformed values.
-
KSeF returns a clearance response (either a KSeF number confirming acceptance, or a rejection).
-
The supplier gets clearance confirmation from Sovos.
-
KSeF delivers the cleared invoice to the buyer through the KSeF portal or other channels.
Invoices can be delivered outside KSeF only to specific recipient categories (Article 106gb(4)), including foreign entities, consumers, entities without a Polish VAT ID, and SME-exempt taxpayers. Domestic B2B recipients with a Polish VAT ID must always get their invoices through KSeF.
Supported documents and transactions
All document types use the same Sovos product ID. Poland's FA(3) schema supports multiple document variants through the RodzajFaktury (invoice type) field.
| Document type | Local name | Sovos product ID | Description |
|---|---|---|---|
| Invoice | Faktura (FA) | pl_Faktura__2.0 | Standard B2B/B2C invoice using FA(3) schema. |
| Corrective invoice | Faktura korygujaca | pl_Faktura__2.0 | Credit note or adjustment document. |
| Advance invoice | Faktura zaliczkowa | pl_Faktura__2.0 | Advance payment invoice. |
| Final invoice | Faktura koncowa | pl_Faktura__2.0 | Final settlement after advance payments. |
For inbound invoice retrieval, use product ID pl_Faktura_Polling_2.0.
