FAQ accounting
Discover the questions our users frequently ask us about accounting software.
Which VAT methods are available?
VAT can be settled according to both the effective and the balance/flat rate method. In the case of effective taxation, the gross or net method can be used for accounting.
These settings are defined when the account is created for the financial year. Once an entry has been made on the respective financial year, no more changes can be made, therefore we recommend choosing this setting carefully.
How can manual entries be made?
Manual entries can be made both in the account statement and in the journal. The option in the journal is part of the Advanced accounting module. Manual bookings can be entered individually with an attachment, in foreign currency with an automated conversion rate or as a split booking.
Which bank interfaces are available?
In total, there are interfaces to more than 70 Swiss banks. You can find an overview of all supported banks under the followingLink. If your bank is not listed, you can also import or export the bank files (CAMT, PAIN) manually.
Can payments be triggered directly from 21.AbaNinja?
The payment orders entered for the respective supplier documents can be transmitted directly to E-Banking via the bank interfaces. For security and possible legal reasons (Money Laundering Act / GwG), the payments must still be released in e-banking each time.
Can bookings be cancelled?
In principle, the mechanism that applies is that cancellations must always be made at the source. This means that bookings that were created automatically by invoices, supplier documents or payments can only be cancelled by cancelling the respective documents or transactions. Manual entries can be cancelled directly in the account statement or journal.
