Hi Emile, so I didn’t really see a question in your post but I will assume that you need help setting up the services that you charge in QuickBooks. As far as items go, anything that you want to appear on an invoice must be set up in the products and services list first. If these are items that you also purchase from your suppliers then you will mark the following boxes in the item setup screen:
1. I sell this product/service to my customers (below this box you will enter the description of the item and the price you sell it for or you can leave it blank and fill it out on the invoice)
2. I purchase this product/service from a vendor (below this box you will enter the description of the item that you use to order it and the price that you pay for it)
All of the additional info you need to set up your products/services is covered in our video tutorial, I have included the link below: https://fitsmallbusiness.com/set-up-products-services-quickbooks-online/
Thank you for reading!
