The Full BreakdownHow ShipSherlock Works
From connection to recovery — here's exactly what happens when you sign up.
The Problem
Carriers like UPS, FedEx, and Canada Post overcharge on roughly 10% of shipments. These aren't rounding errors — they're late-delivery guarantees that should be refunded, duplicate charges, invalid surcharges, and incorrect weight calculations that add up to thousands of dollars per year.
The problem? Most businesses don't have time to audit every line item on every invoice. And carriers know it. They count on you being too busy to notice.
To make it worse, refund claims must be filed within 15 days of the invoice date. Miss that window and the money is gone forever. Every week you wait is money left on the table.
The Process, Step by Step
Four steps. Two minutes of your time. Everything else is on us.
Connect Your Carrier Accounts
Create your ShipSherlock account and add a payment method. Your card is never charged unless we find money— it's only on file so we can bill our share when carrier credits are confirmed.
Then connect your UPS, FedEx, Canada Post, or Purolator account via secure OAuth. We get read-only access to your invoices — nothing more. The entire setup takes about 2 minutes. For UPS and FedEx, invoices are pulled automatically every dayonce connected — one-time setup, then completely hands-off.
We Audit Every Invoice
For UPS and FedEx, ShipSherlock pulls your invoices automatically every morning at 6 AM and audits them immediately. Our AI-powered analysis checks for 6 types of billing errorsacross every shipment — guaranteed service refunds, duplicate charges, voided shipments still billed, incorrect surcharges, weight and dimension discrepancies, and invalid address correction fees. Overcharges are flagged automatically — no waiting, no delays.
No manual work on your end. No spreadsheets to review. We handle the entire audit process automatically, comparing your invoices against carrier service guarantees and contracted rates. We support all four major Canadian carriers: UPS, FedEx, Canada Post, and Purolator— with UPS and FedEx fully automated end-to-end.
We File Claims Automatically
When we find errors, we file refund claims directly with your carrier — automatically and well within the 15-day filing window. Every claim is submitted with the proper documentation and tracking information to maximize approval rates.
You don't need to do anything. No forms to fill out, no phone calls to make, no portals to log into. We handle the entire claims process from filing to follow-up.
And if a carrier denies a claim? ShipSherlock automatically appeals with strengthened evidence— additional documentation, corrected formatting, and escalation to the right department. Most denied claims that deserve approval get overturned on appeal. That means more money recovered for you, with zero extra effort.
You Get Credits on Your Bill
When the carrier approves a claim, the credit appears directly on your carrier bill. You'll see it in your ShipSherlock dashboard too, with full transparency into what was found and recovered.
At the end of each month, we invoice 50% of confirmed credits. That's it. If we didn't find anything in a given month, your card is never charged. Nothing found = $0 owed.
What We Check
Six categories of billing errors we scan for on every single invoice.
Guaranteed Service Refunds
When a carrier promises delivery by a certain date and misses it, you're entitled to a full refund on that shipment. Most businesses never check. We track every guaranteed-service package and file claims on late deliveries automatically.
Duplicate Charges
The same shipment billed twice on the same invoice or across consecutive invoices. It happens more often than you'd think, especially with high-volume accounts. We cross-reference every tracking number to catch duplicates.
Voided Shipments Billed
You cancelled a shipment but the charge still showed up on your invoice. Carriers don't always process voids correctly, and the charge slips through. We identify these phantom charges and recover the full amount.
Incorrect Surcharges
Residential surcharges applied to commercial addresses. Extended area fees on standard zones. Fuel surcharges calculated incorrectly. We verify every surcharge line item against the actual shipment details and dispute the invalid ones.
Weight & Dimension Errors
Carriers sometimes apply incorrect dimensional weight or actual weight to your shipments, bumping you into a higher rate tier. We cross-check billed weights against shipment data and dispute any discrepancies.
Address Correction Fees
Carriers charge address correction fees when they adjust a delivery address — but many of these corrections are invalid or unnecessary. We identify improper address correction charges and file for refunds on each one.
Frequently Asked Questions
Is my carrier data safe?
Absolutely. We connect via OAuth, which means we never see or store your carrier login credentials. We only request read-only access to your invoices and shipment data. All data is encrypted in transit and at rest. We never share your data with third parties.
What if you don't find any errors?
Then you pay nothing. Your card is only charged when carrier credits are confirmed on your account. If we audit your invoices for a month and find zero errors, your bill from us is $0. There is no minimum fee, no monthly subscription, and no setup cost.
Which carriers do you support?
We support all four major Canadian carriers: UPS, FedEx, Canada Post, and Purolator. UPS and FedEx are fully automated — invoices are pulled and audited daily with no manual work. Canada Post and Purolator are supported via tracking and CSV audit. If you use a carrier we don't list here, reach out and we'll let you know when it's available.
How long until I see results?
For UPS and FedEx, your first audit runs within 24 hours of connecting — invoices are pulled automatically every morning. If errors are found, claims are filed immediately. Carrier approval timelines vary — most credits appear within 1–3 weeks of filing. If a claim is denied, we automatically appeal. You'll see everything in your dashboard in real time.
Can I cancel anytime?
Yes. Disconnect your carrier accounts from your dashboard and we stop auditing immediately. There are no cancellation fees, no lock-in periods, and no long-term contracts. Any credits already confirmed before cancellation will still be invoiced at the standard 50% rate.
