Hi there, jdriver.

Thanks for getting back to us.

While we're unable to recommend what app to use, you can enter a specific keyword in the search bar or browse the Category section of the Apps Center to filter the results. Before subscribing to any app or services, I suggest reading some reviews online or trying their trial options available to ensure that you'll find all of the features you need.

Additionally, here's are some articles that you can read to track manage your billable expenses in QuickBooks Online:

• Enter billable expenses

• Enter and manage expenses

• How to enter billable time by job

Just drop me a comment below if you have any other questions and I'll get back to you as quickly as possible.
