Historical sync with QBO - from an accounting perspective, historical sync is a MUST for any sales platform. Most apps I've used offer this feature and do not charge anything extra for the integration itself. The fact that the Boulevard <> QBO integration is $45/location/month and only begins syncing sales data from the date of integration forward is highly disappointing. If I can find a third-party app that will provide those features, I will definitely switch and cancel my Boulevard integration subscription.
