Hey there hollowpointranch,

Thanks for reaching out to us here. QuickBooks Online is a great tool able to help keep your books balanced. Making sure you're recording your transactions properly is an essential step for maintaining clean books. I would be happy to point you in the right direction. 

To ensure accuracy in your books, I recommend reaching out to an accounting professional for expert advice. They'll be able to guide you on the right track and get you back to your QuickBooks goals. You can add your accountant to your books by going to the My Accountant tab of your QuickBooks account. You can also find an accountant that has experience using QuickBooks near you by clicking on the Find a pro to help option in that section.

If you have any other questions, feel free to reach out here.
