Hi there, @brianshaw-transp. I'd like to clarify some things to isolate your concern about the purchases and expenses totals showing differently.
May I ask what specific report you're trying to run? Kindly provide additional information what amounts aren't matching. We'd appreciate it as well if you share some snapshots of the page.
You'll want to review the amount that appears to be incorrect by clicking on the amount itself. It will then bring up more details about it. After that, if necessary, make any adjustments from there.
