Reporting a sync issue

To help us resolve your issue faster, please include:

  • The email address on your MQSync account
  • The project and task involved
  • The approximate date and time of the sync
  • Any error message shown in your sync log

Many common questions — connecting QuickBooks, seeding data, scheduling syncs — are answered on our FAQ and in the in-app guidance on each setup page.

Note: MQSync supports QuickBooks Online (US) only.
