Putting on a backlog of bills. Put on January-fine. Try to put on Feb and when I go into supplier, Jan is still there and adds the 2 together. What am I doing wrong?

Hello there, @manager24!

You'll have to make sure to select the appropriate date upon recording your bills to avoid creating a duplicate transaction. You can read through this article to learn more: Enter and pay bills.

Lastly, here's a few articles you can read to help manage your vendors and expenses: Manage Suppliers and Expenses for QuickBooks Online.

Keep me posted in the comments if you have any other questions. I'll be here to help.
