This one never costs you money; it makes you money, saves you stress and is really no work for you. What does it do? They audit your UPS and FedEx invoices, looking for damaged or late shipments, surprise fees, and credits you’re due. They’ll make sure you’re getting your negotiated pricing and provide analytics you can use to negotiate better rates. They get a cut of what they get back for you. So, it isn’t really free, but they are finding you money you may not know you have coming and don’t have time to look for. Don’t you wish everyone only got paid after they made you money?
