QuickBooks Online sync error: Business Validation Error: You must select a client for each split line that is billable

Why the sync error occurs

This error occurs when the billable box in the customer/job field on a bill is selected and the field isn't needed.

How to fix the sync error

First, check Bill.com to see if Customers/Jobs are enabled for Payables. If not, follow these steps to enable:

1. Select Settings
2. Select Preferences under Accounting
3. If Use Customers/Jobs in Payables is set to NO, Select edit and set to YES
4. Select Save
5. Once enabled, open the bill with the error and select edit
6. Select Customer: Job on each line of the bill to see if Billable is checked
7. If yes, deselect Billable on each applicable line item
8. Select Save
9. Sync again

If the billable box doesn't appear, it is because there are no customers listed in Bill.com. Add a customer in Bill.com by following the steps below, and then edit the bill to enable the billable box to appear:

1. Select Customers in the navigation menu
2. Select Add customer
3. Enter the required fields
4. Select Save

If you don't need customers/jobs in payables, follow the steps above to disable that preference in your Accounting Preferences.
