Hi @JPP_Accounts 

If you are looking for an alternative way of importing Product and Services lists into QuickBooks Online that is not restricted by the number of rows you can import at one time, has the added advantage of being able to import Inventory, Service, Non-inventory and Categories that supports Multiple levels ie Feature:Water:Fountains:Marble fountain 3ft as well as a extensive number of fields like Preferred Vendor, Reorder point, Tax Classification etc. then you could look at Zed Axis that you can find in the Intuit Marketplace,

I hope that is another alternative
