Unaudited Freight Invoices
Companies overpay carriers and 3PLs because invoices are paid without systematic auditing against contracts, quotes, and proof-of-delivery.
In their words
making sure that every operator closes out their invoices
Worst part was it always surfaced downstream so we'd end up reissuing and chasing.
most companies that are active in my line of work already have a management app like mine and they pay way too much for it
I get at least 4-5 of these a week for the last couple weeks... they get postage due every time, anywhere between $7-9.
Paperwork will say 9. Pet connect will say 14. Actual number is something random. Every single week.
Almost every shipment ends up costing ₹30–40 extra. Raising disputes means collecting photos, invoices, packaging proofs, etc., and it's becoming a full-time job.
When it’s actually clean like that and they still say no — are you paying the carrier out of pocket, pushing back, or just denying and moving on?
We still get adjustments from all 3 carriers with impossible weights and sizes
Just got a 9 page invoice with line items I've never heard of, account maintenance fees, zone surcharge variances, receiving adjustments.
Arguing with suppliers...all their 'mistakes' seem to favour them.
ALL of my counts are wrong because the inventory was updated as if we received the truck
does the shipper get billed twice for it? Or does someone else have to actually audit the delivery and their account?
Shippers, brokers, 3PLs
Where they talk

- r/3PL
- r/logistics
- r/freightforwarding
- r/UPS

- r/smallbusiness
- r/SupplyChainLogistics
Tools they use today
- UPS
- FedEx
- Excel
- Google Sheets
- QuickBooks
- Shopify
- USPS
- agentic AI
Why those fall short
- validation often not charged; manual corrective values are wrong and underpriced
- no automated way to prove dimensions and track disputes
- adjustments with impossible weights and sizes; disputes take 30 minutes
- no accountability, tickets closed, weight disputes unresolved, support copy-paste
- No automatic reversal; decades-old systems never upgraded
