Can I check the budget and review expenditure when approving a transaction?

Yes, ExpensePlus makes it easy for category approvers to keep track of expenditure against their budget. 

Within the daily approval notification emails and on the Approvals screen, the year-to-date total for each category is shown in the second to end column of the table. 

Furthermore, the report button at the end of each line (highlighted to the right of the table) will open up the full category expenditure report for you to review.
