The Business Problem

One workflow, always in sync with QuickBooks

Crown Trophy runs a busy awards-and-engraving operation — quotes, orders, production, artwork, pickup and invoicing — while their accounting lives in QuickBooks. Re-keying data between the workflow and QuickBooks was slow and error-prone.

They needed Crown Workflow to talk to QuickBooks both ways and in both worlds: QuickBooks Online for cloud users and QuickBooks Desktop for on-site accounting — staying accurate even when a location briefly drops offline.
