The main purpose of the Taxumo Books of Accounts is for you to have a reference that you can easily copy into your manual books of accounts. The formatting complies with the expected formatting of the BIR for companies that use cash accounting.
​
To use Taxumo's Books of Accounts as your official books, you will need to file a form with the BIR that asks for approval to use a "loose leaf books of accounts." Once approved, Taxumo's Books of Accounts are now officially your books of accounts.

Otherwise, you can of course, just copy the entries from the books of accounts reports to your manual books of accounts.
