Über dieses Produkt
KSeF compliance, built into your Business Central tenant
Poland's mandatory e-invoicing through KSeF (Krajowy System e-Faktur) changes how every VAT-registered business issues and receives invoices. This is not an off-the-shelf AppSource download — it is a build-to-order AL extension that ECOSIRE designs, builds, and installs directly into your Dynamics 365 Business Central environment, then supports as the schema and API evolve.
We deliver it as a per-tenant extension (or an AppSource-technical-type package where you prefer), so it lives inside your tenant without forcing you onto a generic, one-size-fits-all connector. The extension maps your posted sales invoices and credit memos to the FA(3) structured XML schema using AL table and page extensions over the standard Sales Invoice Header/Sales Cr.Memo Header records, validates them, and submits them to the KSeF gateway.
What the extension does on your tenant
Submission runs through a job queue entry so invoices flow to the Ministry of Finance KSeF API automatically after posting — or on demand from a Role Center action. The extension authenticates with your KSeF authorization token or qualified certificate / seal, stored securely using isolated storage, retrieves the UPO (Urzędowe Poświadczenie Odbioru) confirmation, and writes the assigned KSeF reference number back onto the document. Inbound invoices issued to your NIP are pulled from KSeF on a schedule and staged for review.
Every API call, status transition, and UPO is logged to a dedicated ledger table for audit. We wire permission sets, retry/backoff handling, environment-aware endpoints (test vs production KSeF), and — where it helps your finance team — surface status in Power BI or Dataverse via the Business Central OData/REST API.
ECOSIRE scopes the build against your actual posting flows, delivers it on an honest lead time, and stays on for updates as KSeF specifications change.

Häufig gestellte Fragen zu Poland KSeF E-Invoicing for Business Central
Is this an instant AppSource download?
No. This is a build-to-order extension. ECOSIRE scopes it against your actual Business Central posting flows and KSeF onboarding (token vs certificate/seal), builds the AL extension, and installs it into your tenant. It is honest custom work delivered to your environment, not a generic one-click app from AppSource.
What is the delivery lead time?
A standard build is typically delivered in about one working week from the kickoff and access being granted, depending on the complexity of your posting flows, the number of legal entities, and whether you need inbound download and Power BI/Dataverse surfacing on day one. We confirm the exact timeline in writing during scoping and validate against the KSeF test gateway in a sandbox before go-live.
How does ongoing support and updates work?
The price includes a support and update window after go-live. KSeF schema and API details change as the Ministry of Finance finalizes the mandate, so we maintain the extension against the current FA(3) schema and endpoints during that window. After it ends, you can extend support on an agreed plan, or you hold the source AL project under license and maintain it yourself.
Will it work on Business Central online (SaaS) and on-premises?
Yes. It is built in AL as a standard extension, installable on Business Central online (SaaS) as a per-tenant extension or on an on-premises deployment. Isolated storage, job queue, and the REST/OData integration points used are available on both, so the same codebase targets your environment.
Does it change or break the standard Business Central base app?
No. It uses table and page extensions plus event subscribers on the standard posting routines, so it layers on top of the base application without modifying it. That keeps your tenant upgradeable and lets the KSeF extension be updated independently as the specification evolves.
