MEPSub is the all-in-one platform for mechanical, HVAC, BMS and service contractors. Dispatch your crews, run field work from any phone, and turn completed jobs into invoices — without switching apps.
Stop stitching together a scheduler, a spreadsheet, and three other apps. MEPSub covers the full workflow of a mechanical 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.
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.
Sync accounting, message customers, and connect your own systems through a public API and outbound webhooks.
Create your workspace and see the whole flow — schedule, field, and invoicing — working together today.
