Hello mstagg,
Let’s go to your expense and split it between businesses.
You can split it by entering the data into two or more lines to allocate the amounts. For example:
With a bus fare of $20, you can split it into two accounts and have the other one billable to a customer.
- Fare expense $10 (yours)
- Fare expense $10 billable to John
This can be done using a service item set as "reimbursed incur it and charge it to my customer" so that you link the fare to your own Fare expense account and to your own revenue or income account.
This way, you'll see $20 total fare cost and when you charge the customer, you'll see $10 total income.
Also, you can reduce the created transaction and recreate another transaction and split them by lines.
Don't hesitate to leave a comment below if you have any other questions.
