Vouching provides 3-way matching of purchase orders, receiving and invoices.  For all invoices received, the original PO can be pulled and compared for consistency.  If an adjustment needs to be made based upon quantity received or a price adjustment, the system will automatically update the original order gross profit and commissions paid.

Connection to PromoStandards allows for the vendor invoice to be retrieved electronically and compare on-screen.  View you PO against the vendor invoice, make the needed adjustments and process to update to QuickBooks or another connected accounting system.
