Compass KSeF – Application

A web application for handling KSeF designed for small and medium-sized businesses. Send invoices, receive documents from contractors, download official confirmations (UPO). No IT integration needed – start in just one day.

Compass KSeF Application is a browser-based platform that enables companies to communicate with the National e-Invoicing System (KSeF) without having to integrate it with their existing accounting or ERP systems. The solution operates in a subscription-based (SaaS) model—users log in through a web browser, send invoices to KSeF, and receive documents from contractors. All technical infrastructure, updates, and regulatory compliance are handled by the provider.

Who is it for?

For companies that need a simple, secure, and ready-to-use solution for handling invoices in KSeF—without involving their IT department or running complex integration projects.

Small and medium-sized businesses without an IT department – companies with a few to several dozen employees that need to meet KSeF requirements without involving developers or external integrators.
Accounting offices and bookkeeping service providers – organizations serving multiple clients and needing one tool to manage KSeF communication for various entities.
Companies with simple invoice workflows – organizations issuing up to several hundred invoices per month, for which dedicated system integration would be an unnecessary expense.
Entrepreneurs starting a business – new companies that want to comply with KSeF requirements from day one without investing in IT infrastructure.

How quickly can you start?

Implementing the Compass KSeF Application takes one business day. The process includes:

creating an account and configuring company data,
authorizing the connection to KSeF (via token or qualified seal),
short user training (available video materials and documentation),
and starting production use.

There is no need to install software, configure servers, or involve the IT department.

What is the application not?

Compass KSeF Application focuses on communication with KSeF—it does not replace your accounting or ERP system. Invoices are still created in your existing system (e.g., Comarch Optima, Sage Symfonia, wFirma, Subiekt), and the application is used to send them to KSeF and manage document workflows within the National e-Invoicing System.

For companies requiring deeper ERP integration, Compass KSeF API Connector is available.
