Hi Sinoed09,
Welcome to QuickBooks Community! QuickBooks Desktop provides the features you need, to complete your daily tasks seamlessly. I'd be glad to provide more information, so you're on the right track with your work!
Before assessing finance charges, you'll need to set up the preferences. Here's a helpful guide, for your reference. For additional assistance, I recommend speaking with an accounting professional. If you don't have an accountant, we can help you locate a ProAdvisor in your local area.
If you have any other questions, please feel free to reach back out. We'd be happy to help!
