How do you audit 3PL invoices with endless line item codes?
Third-party logistics invoices arrive as weekly walls of confusing codes and line items that make it impossible to tell if charges match the rate card or actual order volume. Manually reconciling every entry against order exports and shipping data takes forever, forcing businesses to absorb hidden fees, incorrect weights, and duplicate charges.

“3PL invoice this month was $9k and order volume is not up enough to explain doubling our costs. the invoices are impossible to read since they are 8 pages of line items with codes”source ↗
“I tried to get an explanation but got the same breakdown back with no actual context and I'm pretty sure they're charging us for services we don't use or things that should be in the base rate but auditing every line item would take forever”source ↗
“When we finally reconciled against the rate card + order export, we found stuff like: 1. Storage billed on peak inventory, not average 2. DIM / weight wrong vs what shipped 3. Minimums applied when volume should’ve waived them 4. Extra picks / inserts charged when the order didn’t have them 5. Charges on cancelled / refunded orders 6. Fee codes that weren’t on the signed rate card 7. Duplicate order charges 8. Billed units ≠ Shopify units 9. Simple math errors on the invoice total”source ↗
“Invoice comes in weekly with a wall of codes — pick/pack, extras, storage, receiving, returns, materials, “accessorials.””source ↗
