An open balance on customers in QuickBooks can occur when the follow pattern of events happens:
- On 7/11/18, invoice #11339 is created with total amount of $0.00 in Printavo and synced to QuickBooks.
- At 7/13/18, the total amount was changed to $1,395 in Printavo and is synced to QuickBooks. This is when the customer open balance got changed to: $1,395.
- Subsequently, there was an update on the customer, that resulted in an invoice for an open balance amount of $1,395.
This issue can be corrected by not syncing invoices with a $0 amount.
