eBarimt Printer-НӨАТУС хэвлэгч is a free Android application developed by SMARTERP. This program allows taxpayers to issue invoices for VAT and other taxes using their mobile phones. According to the developer, the app complies with Mongolian tax laws and can be used by individuals, legal entities, and entrepreneurs.

The app requires users to register with their email addresses to create an account. Once registered, users can issue invoices, store them, and send them to their clients via email. The app also allows users to view their transaction history and track their unpaid invoices.

Overall, eBarimt Printer-НӨАТУС хэвлэгч seems to be a convenient and practical solution for those who need to issue invoices on the go. However, we have not tested the app's compliance with Mongolian tax laws, so we cannot guarantee its accuracy. As always, we recommend users to consult with their tax advisors before using any tax-related software.
