About

We build the software we wished we had

MEPSub is built by an MEP & controls contractor, for MEP contractors — one platform for the way the trade actually runs, from the schedule board to the final invoice.

It started on the job

Born out of running real jobs — not a whiteboard

MEPSub grew out of a working MEP & controls contractor. Between project work and a book of service accounts, the same problem kept coming up: the schedule, the crews in the field, and the invoices all lived in different apps and spreadsheets that never talked to each other.

Jobs slipped through the cracks. Hours got re-typed. Invoices went out late. So the team did what contractors do — they built the tool they needed, shaped by real workflows and the realities of the field.

That tool became MEPSub, and now it's open to other contractors who've been fighting the same fight.

Our mission

Give MEP contractors one platform that runs the whole job — so nothing falls through the cracks.

From the first call to cash, MEPSub keeps the office, the field, and the money on the same page — built for how mechanical, electrical, plumbing, HVAC and BMS shops actually work.

What we believe

The principles behind the product

Every decision in MEPSub comes back to these.

Built for the field

The work happens on the roof and in the mechanical room, not at a desk. If it isn't simple on a phone with gloves on, it isn't done.

One platform, not ten

The schedule, the crews, the parts and the money belong together. One source of truth means no re-keying and no lost jobs.

Your data is yours

Export it, connect it through our API, take it anywhere. We earn your business every month — not with lock-in.

Made by people who've run the jobs

Features come from real MEP workflows and real headaches — not a product roadmap dreamed up far from the field.

We're not a software company that discovered contractors

We're contractors who got tired of the tools and built better ones. That's why MEPSub fits the trade — because it came from inside it.
