Looking for help with how Trade Gecko-Ecommerce integrates. How do I follow an invoice through the integration through to receipt of payment, many are incorrect?

Hello there Sandra and welcome to the Community,

QuickBooks Commerce, formerly known as TradeGecko, is an app that's available to you in the QuickBooks Online Apps section. It works seamlessly with QuickBooks Online to allow you to sell your products without having to update your accounting and inventory details. Since you're looking to learn more about the integration as well as the invoice to receipt of payment process, let me point you in the right direction.

Here in the QuickBooks Community, my team and our users provide support and guidance on how to use QuickBooks to effectively manage the books for your business. While QuickBooks Commerce is owned by Intuit now, the support for this app is a little different than support for QuickBooks. You can learn more about the integration with QuickBooks by navigating to the Apps tab from the left and using the search function to search for QuickBooks Commerce or TradeGecko. 

For more information beyond what's provided there, you can contact the support team here or use the options for support that are available from the tab for the app within QuickBooks. There's a contact email and phone number available for you to reach out.

Let me know if you come up with any QuickBooks-related questions and I'd be happy to give you a hand. Have a great day!
