Every crew, every site, one program
Plan engineers and crews across all your live jobs instead of one whiteboard per site. Timesheets and site records flow back daily, so progress against program is something you check, not something you chase.
Software for HVAC, Mechanical & MEP Contractors
One system for the whole package: estimating and bidding, crew scheduling and timesheets, drawings and site records, plant procurement, variations, applications for payment. You can see where every job stands, every day, from first bid to final account.




























You win the job on price. Then you deliver it with crews spread across sites, kit on long lead times and a scope that never stops moving.

Plan engineers and crews across all your live jobs instead of one whiteboard per site. Timesheets and site records flow back daily, so progress against program is something you check, not something you chase.

Chillers, AHUs and switchgear get ordered months before install. Every PO hits the budget as committed cost the moment it is raised, and deliveries sit on the tasks they gate, so a slipping delivery shows up in the program early.

Design changes and site instructions get captured, priced and approved with the paper trail attached. They carry straight into your application, so you get paid for what you actually installed.
Archdesk is built for specialist contractors delivering HVAC, mechanical, and full MEP packages, whether you work direct for clients or as a subcontractor to a main contractor. Estimators, project managers, site supervisors and the commercial team work from the same records, so the estimate you won with becomes the budget you track against, the drawing on site is always the current revision, and the work you record on site becomes the application you get paid on.
Delivering other trades alongside mechanical? Archdesk also serves:

One live position for the package: program, budget, committed cost and applications in the same view.
What you priced is what you track. The winning estimate becomes the budget, actuals land against it line by line, and what jobs really cost feeds the next bid.
Explore Job Costing
The schedule connected to what it depends on: long-lead deliveries on the tasks they gate, crews planned across every live job, slippage shown with its cost.
Explore Scheduling
Buy-out without the gaps: RFQs from your BOQ lines, bids back comparable, exclusions visible before award. Then every PO and subcontract lands on the budget the moment it's raised.
Explore Procurement
Committed at the PO, earned as work is delivered, invoiced months later. See all three stages against every budget line, so variance is a decision you make, not a number you explain.
Explore Cost Controlling
Certify subcontractor valuations down, build client applications up, from the same records. Invoices, payment notices and retention on statutory time, with the audit trail attached.
Explore Financials
The schedule, the progress and the money in one system. When a task slips you see what it costs, and when scope changes you see what it does to the schedule. 'On track' means the Gantt chart and the bank account.
Explore Project Management
Nobody builds from a superseded drawing. Revision control, approvals and distribution with proof of who received what, when. The record that wins the dispute instead of losing it.
Explore Document Management
Every project's position, live, from the data that ran the work. Cost, schedule and cash agree with each other because they're the same records. There's nothing to assemble and nothing to reconcile.

Archdesk helps HVAC, mechanical and MEP contractors manage estimating and bidding, crew scheduling and timesheets, site forms and progress records, drawings and documents, plant and material procurement, variations, payment applications, and job costing in one connected platform.
Yes. Technicians and site teams record timesheets, complete site forms and log progress from their phones. What they record lands against the project in real time, so the office sees hours and progress without chasing paperwork at the end of the week.
Yes. Drawings and technical documents are revision controlled, with approvals and distribution tracked, so site teams always install from the current revision. Because every record lives against the project, the documentation you need at handover is already in one place.
Yes. Timesheets from site land against each project's budget lines, so you see labor burn against estimate for every live job, week by week, instead of finding out at the final account.
Purchase orders for plant like chillers, AHUs and switchgear hit the project budget as committed cost the moment they are raised. Deliveries are tracked against the installation tasks they gate, so a slipping delivery shows up in the program early, not on site.
Yes. Site instructions and design changes are captured, priced and pushed through approval with the record attached. Approved variations carry into your payment application, so unpriced work stops leaking margin.
Yes. Applications for payment are built from the same records as your measured work and approved variations, and retention is tracked through to release. Everything you apply for is substantiated, which shortens the argument with the main contractor's QS.
Yes. Archdesk integrates with Xero (as a certified partner), Sage, QuickBooks and other accounting systems, so invoices, payments and costs flow between commercial and finance teams without re-keying.
