The amount of time it takes for us to sync your data between Amazon and QuickBooks Online depends on how far back you want the data to be synced and how many orders you have.
For enterprise customers, import times will depend on Amazon API limits. If you have any questions at all, please email us at email@example.com or start a chat and ask us. We're happy to answer any questions you may have.
For many sellers, the syncing will be complete within 24 hours unless problems arise.
Once started, our service works automatically in the background. You do not need to be present, and you can still use QuickBooks Online or handle your Amazon business.
