Hey there, @SusannaT.
Thanks for reaching out to us here in the Community. I hope you're enjoying this day so far.
To clarify, what product are you using along with Point of Sale? For example, are you using QuickBooks Enterprise? If so, it sounds like you could benefit from utilizing the build assembly feature for inventory.
Using the build assembly feature allows you to combine a series of items and sell it as one item. Once your build assembly is created you will call this item 3290. Then, your item 3290 would be a combination of items 354, 951, 1002, and 90. This build assembly will reduce the quantity of the items within it by however many you use for the product 3290. Depending on how many builds you make of 3290 will be how much quantity you contain for that item. Thus when selling 3290, your inventory will reduce just as selling single items, such as item 354.
You can see the full details outlined in Combine your inventory items to build finished goods.
I'll be sure to keep an eye out for your response. Please let me know if you have additional questions or concerns. Take care!
