First Steps with Biurko

Welcome to Biurko. The app is here so that a micro business — a sole proprietorship or a limited company — runs itself as far as that is possible: invoices and KSeF, the registers and the files the tax office expects, and on ryczałt the ZUS contributions and the tax advance as well. This guide shows where to start.

Creating Your Account

To begin using Biurko, register with your email address and create a secure password. After confirming your email, you will be directed to your dashboard where you can set up your first company profile. Each account supports multiple companies, making it easy to manage invoicing for different business entities from a single login.

Setting Up Your Company

Once logged in, navigate to the company setup section. You will need your company's NIP (tax identification number) and basic business details. Biurko will then guide you through connecting to a KSeF environment -- whether you want to start with the test environment for practice or go directly to production.

Overview of Key Features

• Invoice management -- create, edit, and track invoices through every stage of the KSeF workflow.
• Sending to KSeF -- transmit the invoice to the National e-Invoice System; the UPO, the official confirmation of receipt, comes back and stays with the document.
• Status monitoring -- follow the state of every invoice in real time.
• Transmission history -- the full record of submissions and of the answers KSeF sent back.
• Registers and files for the tax office -- for an actively registered VAT payer, the VAT registers and the JPK_V7; on ryczałt, the revenue ledger and the annual JPK_EWP.
• ZUS contributions and the tax advance -- on ryczałt: the contributions of the month, their deduction from the advance, and the ZUS DRA declaration prepared for you (a KEDU file or a printout). You file it with ZUS yourself -- the app neither sends it nor signs it.
• Company management -- company details, users, roles and permissions; the seat for your accountant is free and does not count against your plan.

We recommend starting with the test environment to familiarize yourself with the platform before submitting real invoices to KSeF. To go deeper, read the article on setting up a company in Biurko.
