PalletProof

Idea

PalletProof catches LTL freight reclassification and reweigh overcharges before they drain a small shipper's margin, and turns each one into a ready-to-send dispute. Small and mid-size businesses that ship freight on pallets get hit with after-the-fact "reclass" and "reweigh" fees when a carrier decides their declared freight class or weight was wrong. PalletProof ingests the original quote, the bill of lading, and the final invoice, flags every charge that doesn't match, and drafts the dispute letter with the deadline tracked, all without requiring the shipper to hit the multi-million-dollar freight spend that freight audit firms require to take them on.

Market gap

Carriers are getting more aggressive about reclassification. Some carriers now reclassify more than half of their LTL shipments using terminal imaging systems, and industry data puts typical misclassification detection at 10 to 15 percent of shipments overall, adding 10 to 20 percent on top of the base rate when it happens (sources below). The tools that exist to catch this are built for the wrong customer. Freight audit and payment firms like Cass Information Systems, Trax, and nVision Global serve shippers spending tens of millions to over a billion dollars a year on freight, and blog guidance from freight audit vendors themselves puts the practical entry point for their service at roughly $2 to $3 million in annual freight spend. A small e-commerce brand, furniture maker, or industrial distributor shipping a few dozen pallets a month spends a small fraction of that and gets no coverage at all. The parcel-audit tools that do serve small e-commerce sellers, like Shipware and the small-parcel auditors covered by Intelligent Audit, are built for FedEx and UPS package guarantees, not palletized LTL freight class disputes. Nobody is running this workflow for the shipper who ships freight regularly but not at enterprise scale, and the terminals are scanning more shipments than ever, so the gap is widening, not closing.

Total Addressable Market (TAM)

Bottom-up, starting from public establishment counts:

• The US has approximately 12.1 million employer establishments in total (BLS Quarterly Census of Employment and Wages, 2024 annual averages).
• Wholesale trade, durable-goods manufacturing, and building-materials and furniture retail, the sectors that most regularly ship palletized LTL freight, are conservatively assumed at 4 percent of all US establishments, based on wholesale trade alone being one of BLS's larger sectors. That is roughly 480,000 establishments.
• Assume 25 percent of those establishments ship LTL freight regularly (weekly or monthly, not a one-off pallet a year) and fall below the roughly $2 to $3 million annual freight spend threshold where enterprise freight audit firms engage. That is roughly 120,000 target businesses.
• Blended average revenue per customer: tiered monthly subscription from $99 to $299 depending on shipment volume, blended average $150/month, or $1,800/year.
• TAM: 120,000 x $1,800 = $216M/year.
• SAM: narrow to businesses digitally organized enough to export invoices or forward PDFs (not phone/fax-only operations), assumed at 30 percent of TAM = 36,000 businesses x $1,800 = $64.8M/year.
• SOM: a realistic 3-year capture for a small self-serve team, 2 percent of SAM = 720 customers x $1,800 = ~$1.3M ARR.

Assumptions are stated above; the underlying market-size and threshold figures are sourced in the Sources section.

Monetization strategy

Flat monthly SaaS subscription, tiered by number of LTL shipments processed per month. The shipper pays whether or not a dispute is filed, unlike gainshare/contingency freight audit firms, because the target customer wants a tool they control, not a vendor taking a cut of money that's rightfully theirs. Retention comes from the invoice-ingestion habit: once a shipper forwards invoices to their PalletProof inbox address, checking the flagged-charges dashboard becomes part of their AP routine.

Pricing strategy

• Starter ($99/mo): up to 25 LTL shipments/month, invoice flagging, dispute letter generation, deadline tracking.
• Growth ($199/mo, anchor tier): up to 100 shipments/month, freight class density calculator for pre-shipment classification, multi-carrier dispute deadline rules.
• Scale ($299/mo): up to 300 shipments/month, CSV export for accounting, priority support.
• Entry point: a free no-signup "Freight Invoice X-Ray" that lets a shipper upload one invoice and BOL and see an instant overcharge estimate, converting to Starter once they see a real dollar figure.

Lead magnet

A free, no-signup "Freight Invoice X-Ray": upload one carrier invoice PDF and the original bill of lading, and get back an instant read on whether the shipment was reclassed or reweighed, what the dollar delta is, and whether it's still inside the carrier's dispute window. No account required to see the number; the paywall sits behind ongoing monitoring and dispute-letter generation.

Social proof that the problem exists

• An eBay seller's community thread describing a freight bill that came in $1,110 higher than quoted because the carrier reclassified the shipment onto a larger pallet after pickup: https://community.ebay.com/t5/Shipping/Freight-Charges-1110-more-than-expected-due-to-Larger-Pallet/m-p/29507559/highlight/true
• A separate eBay community thread from a seller charged $100 for a liftgate service they never approved, a common accessorial-fee surprise that rides alongside reclassification: https://community.ebay.com/t5/Shipping/Charged-100-for-Lift-Gate-Service-without-Approval/m-p/34972532/highlight/true

Competitors

• Cass Information Systems (freight audit and payment): serves large enterprise shippers with high invoice volumes on a customized pricing model built around scale, not self-serve small shippers. https://www.cassinfo.com/freight-audit-payment

• NMFTA ClassIT+: the freight classification industry's own digital tool for looking up NMFC codes and reducing reclass disputes, but it is a classification lookup tool, not an invoice-monitoring or dispute-automation product. https://classitplus.nmfta.org/
• Shipware / Intelligent Audit (parcel and small-parcel auditing): built for FedEx/UPS small-package guarantee refunds and dimensional-weight disputes, not palletized LTL freight class and reweigh disputes. https://shipware.com/solutions/invoice-audit-recovery/ and https://www.intelligentaudit.com/blog/what-is-small-parcel-auditing-software-why-do-shippers-need-it

What competitors offer now

Enterprise freight audit and payment firms (Cass, Trax, nVision Global) offer full-service invoice auditing, payment processing, and managed dispute resolution, but they are sold through custom enterprise contracts, integrate with EDI and TMS systems a small shipper doesn't have, and are economically built around shippers spending millions a year, since their fee structures and account-management overhead only pencil out at that scale. NMFTA's ClassIT+ helps a shipper classify freight correctly before shipping, which reduces future disputes but does nothing for the invoice sitting in their inbox right now. Parcel auditors like Shipware, Reveel, and LateShipment.com are genuinely self-serve and built for small e-commerce sellers, but their entire product, from the guarantee rules they check to the carriers they integrate with, is built for FedEx and UPS small-package shipping, not the bill-of-lading, freight-class, and reweigh mechanics of LTL freight.

What can be done differently to attract customers

Own the LTL-specific dispute workflow (BOL vs. invoice class/weight/accessorial comparison, carrier-specific dispute deadlines, dispute letter drafting) as a standalone product priced for the shipper who ships freight regularly but is nowhere near the $2 to $3 million spend enterprise freight audit firms require. Enter through a free, no-signup Freight Invoice X-Ray that gives a real dollar answer in under a minute, the same instant-value pattern that works for financial-recovery tools, and let the shipper see their own overcharge before they're asked to pay anything.
