Expense reimbursement, payment and purchase requisition, and Event ROI tracking. At the basic level this let's each sales person submit expenses. But deeper, it allows for tracking of costs based on events. We create an ROI event for each tradeshow or event. Also includes general departmental categories like "Sales Dept" etc. Then we sync this ROI Event table with Hubspot CRM and other Apps in QB. Allows us to tie revenue to costs.
