Keep a Useful Parcel Record
Save the information needed to compare the order, packed parcel and carrier charges.
Before shipment
Save the item list, selected options, invoices, warehouse measurements and relevant inspection photos.
After choosing a route
Save the route name, quote, packed weight, dimensions, services, tracking number and declarations you supplied.
After delivery
Keep carrier invoices and import documents with the original quote so you can compare any additional charge line by line.
