Best Inventory Software for Plumbers and Plumbing Companies
Plumbers do not need a warehouse WMS. They need to know which van has the 3/4" ball valves and whether the water-heater kit is actually on the truck.
Ask for a van, not a folder
If the demo opens on folders and tags, you are in the wrong product. Ask them to show Truck 12’s quantity of a 1/2" shutoff, then a transfer from the shop, then a scan to job 8801.
If that takes a professional-services quote, walk. This is table stakes for fleet work.
The phone has to survive a wet job
Big buttons. Camera scan. Offline. A photo of the valve. That is the field bar. Desktop-only inventory is a shop tool, and the shop is not where fittings disappear.
FleetStock’s tech view is a phone app on purpose. Office users keep the sidebar. Plumbers keep the scanner.
Kits for the jobs you already know how to sell
Water heaters, disposers, sump pumps, and toilet resets are kits. If your software cannot group those parts, you will keep forgetting the expansion tank and the ball valve that makes the job legal in your city.
A kit is also a training tool. The new plumber does not have to invent the list on the driveway.
Do not buy a second FSM by accident
You may already pay for ServiceTitan, Housecall, or Jobber. You need parts truth, not another dispatch board. Prefer a parts platform that exports job usage over a suite that wants your whole company.
Sortly-style folder apps are the other trap. Fine for a parts room. Blind in the van.
Pay once a year if you can
Per-seat monthly pricing is how inventory never makes it onto the helper’s phone. FleetStock’s yearly plans exist so a five-person shop is not punished for doing the right thing.
Trial it on one van for two weeks. If scans happen, expand. If they do not, the software is not the first problem — the habit is.
FAQ
Is FleetStock built only for HVAC?
No. HVAC, appliance, and plumbing vans are the design center. Fittings and valves are first-class parts.
Can we start with one plumber?
Yes. Starter is one user, one yearly invoice. Add vans when the habit sticks.
Will it print bin labels?
Yes — labels are part of the product so the van and the app use the same name.
