If you are an existing user in Celoxis and decided to switch to QBO you need to first agree on date prior to making the switch. This is important because once you are connected to QBO you can only sync the time entries which in Approved and Billable state. You cannot invoice entries from Celoxis. Invoicing will be done from QBO. Entries in Approved will not have Invoice option however you can delete, reject and modify the fields of time entries.
Time entries Invoiced in Celoxis prior to connecting to QBO will not sync with QBO, If you wish to sync these entries with QBO you need first UnInvoice them so they go back to Approved state and you can sync them with QBO. (Note: Only user with admin rights can UnInvoice Time Entries in Celoxis)
