Stuck at the dock? You're owed money — and HaulClaim gets it back. Every hour you wait past free time is detention pay you earned. Most drivers never collect it, because chasing a broker for a few hundred dollars isn't worth the phone calls and paperwork. HaulClaim does that part for you. HOW IT WORKS 1. Scan your rate confirmation. We pull the detention terms you already agreed to. 2. Tap "Arrived" when you pull into the dock. Your GPS and the timestamp lock in the exact moment — automatically, in the background. 3. Tap "Departed" when you roll out. We calculate the detention you're owed down to the minute. 4. Submit the claim. We file it with the broker, follow up on a schedule, and escalate to the FMCSA surety bond if they drag their feet. 5. Get paid. The broker pays you directly — we never touch your money. BUILT FOR THE CAB, NOT THE OFFICE - Three taps to log a detention event. No forms to fill out at the truck stop later. - Geofenced arrival and departure timestamps document your time the way a broker can't argue with. - Track every claim from filed to paid in one screen. - Works whether you're an owner-operator or leased onto a carrier. WHO IT'S FOR Owner-operators, CDL Class A drivers, flatbed, reefer, and dry van drivers — and the dispatchers and fleet managers who run loads for them. If you run interstate freight in the US, we can file your claims in all fifty states. FREE DURING BETA — YOU KEEP 100% HaulClaim is free while we're in beta, so you keep 100% of every dollar we recover. No fee, even on what we collect. If we collect nothing, you owe nothing — no retainer, no signup fee, no hidden charges. (Pricing may be introduced after the beta; current beta members keep 100% for the full beta period.) WHAT YOU'LL NEED Your rate confirmation for the load. No rate con, no claim — that's the one rule. If you can pull it from email, dispatch, or your factoring portal, we can usually work with it. We're a claims service, not a law firm. We file the paperwork, talk to the broker or carrier, and get you paid. If your situation needs a lawyer, we'll tell you straight. Done eating detention? Download HaulClaim, log your next load, and let us chase the check while you drive.
