How do I connect the sales app Lightspeed?

You need a 3rd party connector app

Hello, @shauna12. Welcome to the QuickBooks Community forum.

@SIAB is correct, you will need a third-party connector app to connect Lightspeed to QuickBooks. I can help you find a suitable connector app using the Find Integrations tool in QuickBooks.

Here's how to locate one:

1. Head to the My Integrations icon in the top right of your screen.
2. Click Find Integrations. 
   
3. In the Search bar, look and browse for "lightspeed connector".
