Hi there ethanrayburn,
It's important that all your transactions be correctly entered so your sales can be accurate. QuickBooks Desktop is a great tool able to help you keep track of sales and ex[enses sp you can see the profit of your business. I can point you in the right direction for assistance with setting up products.
In order to know which way would be the most efficient way to enter your products and services into your item list, I recommend reaching out to the QuickBooks Desktop support team outside of the Community. They'll be able to guide you in all the options available to save you time when adding items in order to see if it's possible to automatically add these numbers. You can reach them using the methods outlined in the QuickBooks Desktop software support policies.
If you have any other questions, feel free to reach out here.
