Frequently Asked Questions

You connect your carrier accounts (UPS, FedEx, or Canada Post) and we do everything else. Each week, we pull your shipping invoices and scan every charge for errors — late deliveries, duplicate charges, invalid surcharges, weight discrepancies, and more. When we find a billing error, we file a refund claim directly with the carrier. Approved credits appear on your carrier account, and we bill our fee at the end of the month.

We currently support UPS, FedEx, and Canada Post — the three major carriers used by Canadian e-commerce businesses. We plan to add more carriers over time. If you use a carrier we don't yet support, let us know at support@shipsherlock.com.

Our fee is 50% of the credits we recover for you. There are no setup fees, monthly fees, or minimum charges. If we don't find any overcharges on your invoices in a given month, you pay nothing. Your card is only charged when credits are confirmed on your carrier account.

At the end of each calendar month, we tally up all the credits that were confirmed on your carrier account(s) during that month. We then charge 50% of that total to the payment method you have on file. You'll receive an itemized invoice by email showing exactly what was recovered and what you're being charged.

Yes. We take data security seriously. Your carrier credentials are stored with encryption, and your payment information is handled entirely by Stripe (a PCI-DSS compliant processor) — we never see or store your full card number. Our infrastructure is hosted on Supabase and Vercel, both of which maintain strong security standards. We also comply with PIPEDA, Canada's federal privacy law. See our Privacy Policy for full details.

Absolutely. You can disconnect your carrier accounts and close your account whenever you want — no cancellation fees, no contracts, no hassle. We'll stop auditing your invoices immediately. Any fees for credits already confirmed before cancellation will still be billed at the end of that billing period. Your personal data is deleted within 30 days of account closure.

Most customers see their first recovered credits within 1 to 3 weeks of connecting a carrier account. The exact timeline depends on your shipping volume and how quickly the carrier processes refund claims. We start auditing your invoices as soon as you connect, so there's no waiting period on our end.

Carriers like UPS and FedEx offer service guarantees on certain shipment types — if a package arrives late, you're entitled to a full refund of shipping charges. These are called Guaranteed Service Refunds (GSR). Many businesses don't realize they're eligible or don't have time to track every delivery. ShipSherlock monitors all your guaranteed-service shipments and automatically files claims for late deliveries.

Nope. Once you connect your carrier account(s) and add a payment method, ShipSherlock runs on autopilot. We pull your invoices, audit every charge, file claims, and track the results. You can check your dashboard anytime to see what we've found, but no action is required from you.

It happens sometimes — not every claim is approved. If a carrier denies a claim, you are not charged anything for that claim. Our fee only applies to credits that are actually confirmed and applied to your carrier account. We also review denials to identify patterns and improve our claim accuracy over time.

We audit for a wide range of billing errors including: late deliveries on guaranteed services (GSR claims), duplicate charges, voided shipments that were still billed, incorrect surcharges (such as residential fees on commercial addresses), weight and dimensional weight discrepancies, and invalid address correction fees. Our audit engine is continuously updated as we identify new error patterns.

Yes. Whether you ship 50 packages a month or 50,000, ShipSherlock can help. Our service scales with your shipping volume — and since you only pay when we recover money, there's zero risk regardless of your size. That said, businesses with higher shipping volumes tend to see more total savings simply because there are more invoices to audit.
