KSeF Integration Tool
The DeliveredSoft KSeF Integration Tool is a dedicated solution designed to manage Poland's mandatory structured e-invoicing directly within Microsoft Dynamics 365 and AX. As the 2026 deadline nears, our tool eliminates the complexity of compliance by automating the end-to-end process of sending, receiving, validating, and archiving invoices through the official government platform. It provides a secure, reliable, and user-friendly bridge between your ERP and KSeF, ensuring business continuity and preventing last-minute compliance issues.
Key benefits
- Guaranteed legal compliance: The solution is continuously updated to meet the latest technical and legal requirements from the Polish Ministry of Finance.
- Full process automation: Eliminates manual data entry and reduces human error by automating the sending of sales invoices and the import of purchase invoices.
- Seamless Dynamics integration: Works as a native part of your D365/AX environment with an intuitive interface, requiring no external applications or extensive user retraining.
- Enhanced data security: Ensures all communication with the KSeF platform is fully encrypted and secure, protecting your sensitive financial data.
- Real-time status tracking: Provides complete visibility into the status of every invoice, with automatic handling of KSeF confirmations (UPO) and clear error messaging.
- Business continuity: Features support for offline invoice issuance and QR code generation, ensuring your operations can continue even without a stable connection to the KSeF platform.
Examples of usage
A user posts a standard sales invoice in Dynamics 365. Our tool automatically validates the data against KSeF requirements, converts it to the required XML format, sends it to the platform, and retrieves the unique KSeF ID, updating the invoice record in D365—all in one seamless process.
The tool automatically connects to the KSeF platform to download new purchase invoices addressed to your company. It then imports them directly into the appropriate Dynamics 365 purchase journal, ready for your standard review and posting procedures.
When a credit note is created in Dynamics 365, the tool automatically links it to the original invoice. It generates the correct structured XML for the correction, sends it to KSeF, and manages the entire validation and confirmation process within your ERP.
A retail company generates hundreds of invoices daily from its Point of Sale (POS) terminals. Our solution aggregates these transactions and transmits them to KSeF in compliance with regulations, ensuring every sale is correctly registered without manual intervention.
How it works?
You continue to create sales invoices, project invoices, and credit notes using your standard, familiar processes within Microsoft Dynamics 365. No changes to your workflow are needed.
With a simple action, our tool validates all required data fields, converts the invoice into the official KSeF XML schema, and securely transmits it to the government platform via its API.
The integration tool automatically listens for a response from KSeF. Once processed, it receives the Official Certificate of Receipt (UPO) and the unique KSeF ID number, updating the transaction in Dynamics 365 to confirm it is legally recognized.
For purchases, the tool periodically polls the KSeF platform. It downloads any new invoices issued to your NIP, converts them into a readable format, and creates records in your D365 purchase invoice journal, ready for processing.
In above section we can see list of all records. On top we see the ones that have difference. As difference we consider lack of record on one of environments or difference in any field on that record. Records with differences have color mark. There is action option “Update from source”. It can be used to easly accept changes coming from source into destination environment.
