Integrating Quickbooks to Squarespace

Hi LorenaSRomero, 

With Squarespace Extensions, you'll be able to connect your Squarespace store with Quickbooks. Check this help guide for more info:

Squarespace Extensions

@srodrigues will sales from an external saas be recorded with the extensions as well?

@holgenuine I am not sure about that. The best approach in this case would be to contact OneSaas directly. 

Check out CartSpan for your integration.  It’s the only product I’ve found to work with the Desktop version of Quickbooks. I have been using this product, without issue, for a couple of years now to connect my Squarespace with my QuickBooks POS.  It imports orders and keeps my stock up-to-date in Squarespace.  They also integrate QuickBooks Accounting and Sage 50 Accounting for anyone else that might be interested.  Product development/support is based in North America and their phone number is displayed in large font at the top of their website.
