WHAT YOU CHARGE. WHAT YOU PAY.
Does what you charge
cover what you pay?
You know what customers paid for shipping. We compare that with your final carrier invoices, including extra fees and credits, so you can see which orders covered their shipping cost and which left a gap.

One fictional month for an equipment store shipping parcels and pallets. Each figure below is sample data.

One order was missing an invoice. An unmatched $9 charge and $12 in account-level fees are tracked separately.
Three checks from the sample
- Test a mixed cart. Check whether checkout covers the separate pallet and parcel on DEMO-04.
- Check free shipping. Confirm whether the $0 shipping charge on DEMO-05 was intentional.
- Review the carrier adjustment. Find the reason for the $5 increase on DEMO-03.
WHAT WOULD MAKE AN AUDIT WORTH IT?
One small gap.
Over and over.
A checkout charge can look right until a split shipment, fuel surcharge, or later adjustment reaches the final bill. ShipGap puts the two amounts together, order by order.
If the changes you make improve your shipping margin by $299, they cover the audit fee. Try your own assumptions to see what a small improvement per shipment could mean.

Does this tell me whether my carrier rates are good?
The core audit shows how your customer shipping charges compare with the final carrier bills. A competitive-rate review also needs your rate agreements and comparable quotes for the same service, routes, shipment sizes, and volume. We can scope that separately as consultation.
