Hi there Cakeman,
It's important that all your transactions are correctly entered for your books to be well balanced. QuickBooks Online is a great tool able to connect to various services through apps designed by third-party developers. I can point you in the right direction for assistance with apps.
QuickBooks Online Itself can't connect directly with Uber Eats to import transactions, but a connection could possibly be established using a third-party app. To see if there is an app available to connect QuickBooks Online to the other software, go to the Apps section of QuickBooks Online, the search for relevant keywords.
If you ave any other questions, feel free to reach out here.
