There are some options that depend on how you are handling your accounts.
1. If you are not using an external accounting package:
You can set up each business as a different user under a Multi-user account. This will allow you to differentiate which expenses relate to which business.
2.If you have different accounting package accounts for your businesses:
It will be necessary to have a separate corresponding Receipt Bank account for each of them.
Currently it is only possible to integrate one Receipt Bank account with one accounting package at any one time.
3.If you are an Accountant or a Bookkeeper:
Definitely the best choice for you would be our 'Partner Programme'!
