Let me share information and help you link those two programs in QuickBooks, Ddgwales.
QuickBooks Self-Employed (QBSE) can track Etsy sales, though a direct integration with Shopify is unavailable. You can consider upgrading to QuickBooks Online (QBO) to manage Etsy and Shopify sales. Since this plan offers support for e-commerce platforms and includes features for tracking sales and detailed financial reporting.
I'll show you how:
In your QBO account, click the Apps tab on the left menu and go to the Find Apps tab.
Look for the Etsy app in the Search field.
Click the Get app now button.
In a new tab, click the Connect button.
Enter the Etsy login credentials, then finish the integration.
Also, you can repeat the same steps for the Shopify connector.
You may use another QuickBooks account. For now, I suggest checking our QuickBooks Plans and Pricing page to pick a product that fits your business needs.
