If you want to delete absolutely all data, you can delete this base in main menu - Other - My account - menu (3 points in the upper right corner) - Clear database. After that, you'll see the start screen of the app and you can input your email address to register a new database.

If you want to delete only the movements and indicators, but at the same time to save the list of products, clients and prices, you can:

a) independently delete documents with transactions that you previously entered (for example, orders or sales in the section “Orders and Sales”). Thus, the indicators in the database will be cleared, and the products will remain. For removing any object in the database, open this object and select "Delete" in menu (3 points in the upper right corner).

b) if there are many operations, let us know and we will launch a special processing.

You can also simply create a new database, and keep the old one for history. To do this, in the main menu of the application, select All applications - "+" - Boss and enter your email. The application will offer you to connect to your existing database or to create a new one - select the "Add new database" option.
