Good day, acc1vholdings-gm.
Great news because Hike POS is one of the third-party software that can integrate into QuickBooks Online.
From your QuickBooks, go to the Apps tab, then search and select Hike - POS Software, Retail Management, Inventory. From there, you'll more details and articles on how you can set it up. If you have confusion with the integration, it's best to reach out to Hike's Support so they can further assist you with it.
I'll be here if you have more questions. Have a great day and stay safe!
