We're happy to hear from new members reaching out for support in the QuickBooks Community. It's a great place to connect and get answers to your questions.QuickBooks Online has a few options for customizing your forms, and adding your company logo is one of them. I can point you in the right direction for adding your logo to your invoices.
Check out this article: Add, customize, or remove logos on sales forms. It goes through adding the logo, and the specifications needed and common issues. I want to highlight that rectangle logos don't work, and square is recommended.
I'm confident that you've got this; however, if you need a helping hand, I'll be here. Have a magnificent weekend!
