mBiuro is a program that has gained a lot of popularity due to the fact that it was free of charge for some time. Currently, the program is paid for, but it compensates for this with its extended functionality, which is more stable in comparison to free versions. The main task of the program is invoicing of goods and services and keeping warehouse records.

It enables issuing and correcting VAT invoices, entering purchase documents, keeping a sales and purchase VAT register, business partners' files, services, recording goods, issuing PZ and WZ documents, keeping a schedule. A significant advantage of the program is the transparency of the interface and very simple operation.
