KSeF Pro PS
Direct KSeF integration for PrestaShop. Generates FA(2) XML invoices, signs them with XAdES-BES digital signatures, authenticates via KSeF token, manages batch sessions, and downloads UPO confirmations. Works standalone or paired with Fakturownia Pro.
Everything you need for KSeF Pro PS
FA(3) XML — The Only Compliant Module
Since February 2026, the Polish Ministry of Finance requires FA(3) schema for all KSeF submissions — FA(2) is rejected. KSeF Pro is the only PrestaShop module that generates fully compliant FA(3) XML invoices, validated against the official XSD, and signed with XAdES-BES digital signatures.
- FA(3) schema — the mandatory format since February 2026
- XAdES-BES digital signature applied automatically before submission
- Correction FA(3) documents (FK type) for refunds and corrections
- All mandatory FA(3) fields populated from PrestaShop order data
- VAT RR (Reverse Charge) and VAT exempt annotations in XML
- XML sanitization prevents injection attacks in invoice data
Real-Time KSeF Dashboard
A dedicated admin dashboard gives you full visibility into your KSeF submission pipeline. See success/failure rates at a glance, track active sessions, view the submission timeline, monitor offline status, and take quick actions — retry failures, resubmit batches, or download UPO confirmations.
- Submission statistics — total sent, accepted, rejected, pending
- Success/failure rate charts with historical trends
- Active session timeline — open, close, error events
- Quick actions: retry failed submissions, resubmit batch, download UPO
- Offline mode indicator showing real-time KSeF API status
- Per-order KSeF status badges in the orders grid
GTU Codes & MPP Detection
Assign GTU (Grupa Towarów i Usług) codes per product directly in the PrestaShop product admin — all 13 categories required for JPK_VAT reporting. The module also automatically detects B2B transactions over 15,000 PLN and adds the mandatory Split Payment (MPP) annotation to the FA(3) XML.
- 13 GTU categories assignable per product via admin tab
- Bulk GTU assignment for product categories
- GTU codes injected into FA(3) XML GTU fields automatically
- Automatic MPP detection for B2B transactions > 15,000 PLN
- MPP annotation added to FA(3) XML P_18A field
- Both GTU and MPP fully compliant with JPK_VAT reporting requirements
Multi-NIP Seller Profiles
For businesses with multiple tax identities — branches, subsidiaries, or multi-entity operations. Each seller profile has its own KSeF token, NIP, company name, address, and bank account. Assign profiles per order rule or product category. Manage all profiles from a dedicated admin tab.
- Multiple seller profiles with independent KSeF tokens and NIPs
- Per-profile company name, address, and bank account details
- Assign profile per order status rule or product category
- Admin tab for profile management — add, edit, delete, set default
- Profile selected automatically based on order context
Offline 24h Mode
When the KSeF API is down or unreachable, the module switches to offline mode and continues generating invoices locally. When KSeF comes back online, all queued invoices are submitted automatically. Fully compliant with the Ministry of Finance's 24-hour grace period regulation for KSeF outages.
- Automatic failover when KSeF API is unreachable
- Invoices generated and stored locally during outage
- Automatic sync and batch submission when KSeF recovers
- Admin indicator shows real-time KSeF API availability
- Compliant with MF's 24-hour offline grace period regulation
- No manual intervention required — fully automatic recovery
Customer Portal, PDF & Proformas
Customers access their KSeF invoices directly from the My Account tab — download as PDF, see the KSeF-ID, and check submission status. Invoice PDFs are auto-attached to order confirmation emails. Proforma support lets you generate preliminary invoices before KSeF submission and convert them to final FA(3) on payment.
- Customer invoice portal in PrestaShop My Account area
- PDF invoice generation from FA(3) XML — professional layout
- PDF auto-attached to order confirmation email
- PDF caching — instant downloads without regeneration
- Proforma invoices with PDF and email delivery
- Convert proforma to final FA(3) invoice on payment
Batch Sessions & Intelligent Error Recovery
Submit hundreds of invoices in a single KSeF session. The module manages the full lifecycle — opening, submitting, monitoring, closing, and downloading UPO. When errors occur, the batch error parser provides per-invoice details so you know exactly which invoice failed and why.
- Batch submission for high-volume stores
- Intelligent error recovery — per-invoice error details and codes
- UPO (Urzędowe Poświadczenie Odbioru) download per session
- Failed submissions retried automatically with exponential backoff
- Full audit trail — XML payload, HTTP response, KSeF-ID per invoice
- Export audit log to CSV for accountant or tax authority
Paired Mode & REST API
Use KSeF Pro alongside Fakturownia Pro for dual-channel invoicing — FA(3) XML to the government, PDF to the customer, from one status change. Or integrate with external systems via the REST API for headless PrestaShop setups — submit invoices, query status, and download UPO programmatically.
- Paired mode — KSeF sends FA(3) to government, Fakturownia sends PDF to customer
- Shared per-status rule engine with Fakturownia Pro
- REST API — submit, query, download UPO from external systems
- Webhook callbacks for real-time KSeF status updates
- Standalone mode — KSeF only, no Fakturownia needed
