MEPSub is the all-in-one platform for MEP and service contractors — mechanical, electrical, plumbing, HVAC and BMS. Win the work with AI takeoffs and estimates, run crews from any phone, track inventory and safety, and close the books — without switching apps.
Stop stitching together a scheduler, a spreadsheet, and three other apps. MEPSub covers the full workflow of an MEP or service contractor.
A drag-and-drop board and calendar to plan appointments, assign crews, and reschedule in seconds — everyone sees the same live picture.
Techs run the day from any phone — job details, checklists, photos, and a built-in time clock that feeds straight into payroll and job costing.
Build estimates from parts and labor templates, win the work, and turn it into work orders your crews can act on — with cost codes on every line.
One click from a finished job to a sent invoice. Change orders, retainage and AIA G702/G703 progress billing are built in for project work.
Give customers a branded portal to book appointments, review service history, e-sign approvals and pay invoices — without a phone call.
Track every unit you service — model, location, and full history — so recurring PM visits and warranty work are always one lookup away.
Not a chat box in the corner. MEPSub’s AI reads your plans, writes your documents and watches your jobs — working from the data already in your workspace.
Upload a plan set and get a measured, priced material list in minutes — instead of an afternoon with a scale ruler and a highlighter.
Ask about any job, customer or invoice in plain English, and let it draft submittals, emails and scopes of work from your own data.
Automatic warnings when a job’s margin slips, an invoice ages past due, or work stalls — while you can still do something about it.
One click turns job data into a submittal package, a service report, a product spec or a letter — formatted and branded as yours.
Upload the project specification and get back the sections that actually need a submittal — correct CSI titles, suggested manufacturers, and the matching cut sheets. Books still numbered Division 15 and 16 included.
Answers the calls nobody is there to take — books the appointment, takes the message, or hands off to on-call, using the facts about your business that you gave it.
Most contractors run the business across five or six disconnected apps. MEPSub is one system, where the estimate becomes the job, the job becomes the invoice, and the invoice lands in your books.
One login, one place your data lives — instead of six apps that don’t talk to each other.
Whether you're running multi-month project jobs or a book of recurring service accounts, MEPSub fits the way you bill and dispatch.
Manage phased jobs from award to closeout with the financial controls general contractors expect.
Keep a full book of service accounts moving — from the first call to a paid invoice.
The same connected flow every time — nothing falls through the cracks between the office and the field.
Book the appointment or plan the project, then assign it to the right crew on the board.
Techs get the job on their phone with all the details, clock in, and work in field mode.
Capture labor, parts, photos and sign-off on site — costs post back to the job automatically.
Turn the finished work into an invoice, send it, and let clients pay through the portal.
Text and email your customers, take card payments, run your phone system, and connect your own systems through a public API and outbound webhooks.
Connected with you during onboarding
The reason most contractors stay on a system they have outgrown is the move itself. That is the part we built for.
Drop in the exports from your current system — customers, projects, estimates, change orders, invoices, payments, vendors, bills. They import in the right order, and one click undoes the whole run if it is not right.
Answer one question about the kind of work you do and the app arranges itself around it. Anything you do not run — AIA billing, inventory, safety — switches off and stops cluttering the menu. Turn it back on whenever the work changes.
The Free plan is a real account, not a trial that expires on you. Add seats as the crew grows, add modules when you need them, and see what a seat costs before you commit to anything.
Create your workspace and see the whole flow — schedule, field, and invoicing — working together today.
