Using Amazon fulfillment what is the correct way to do inventory and sales in quickbooks?

Hi, @NauticalJim.

You can enable the advanced inventory feature so you can track inventory at different sites or locations. I'll guide you how.

1. Open your QuickBooks Desktop file.
2. Go to the Edit menu, then click on Preferences.
3. On the left pane, choose Items & Inventory then go to the Company Preferences tab.
4. Check the Inventory and Purchase Orders are Active box.
5. Select the Advanced Inventory Settings button. 
6. Mark the box beside Multiple Inventory Sites is enabled, then hit OK.

Once done, you're now ready to set up your inventory sites.

1. From the Lists menu, select Inventory Site List.
2. Select the Site button, then New.
3. Enter the appropriate information.
4. Repeat the same steps until all your sites are set up.

On the other hand, you can create separate items to track sales on each site. With this method, you use a naming method or structure to distinguish between items at different sites. For example, if you have 3 warehouses, you use 3 items to represent the same item located at each warehouse. 

• Item A- Warehouse A or Location A
• Item A- Warehouse B or Location B
• Item A- Warehouse C or Location C
