Hi, I want to import invoices but it always wants to add new products, even though they are already in the system
Glad to have you join the Community. Making sure your inventory is accurate in QBO is vital to any business success. I'd be happy to walk you through ways to import your invoices and other forms so you don't run into hassles in the future.
I've attached a screenshot below. When you click the gear icon > Import Data > Invoice, are you selecting the option I highlighted on the screenshot below? If not, you'd need to make sure it's checked in order to avoid products being added to your account. Let me know if you need help.
