We had a customer who had been using Zahara with Sage for a number of years and switched to Business Central. "We won't be needing Zahara now" they said. One month later, they were back. "Oh, their invoice processing and approvals is horrible compared to Zahara, can we come back?". So let's look into that in a bit more detail. Why would you use Zahara if you already use Dynamics 365?
Once connected, a full sync of BC data can be triggered from within the Integrations section within Business Settings. To sync just one element (Suppliers/Accounts/Etc), head to the corresponding area in Zahara and select the QuickBooks Online Sync button. This will trigger a sync of that one element.
