Don't let a bad GC ruin a good job.

You're commissioning a rooftop unit in July heat. Who's chasing down net-60 from the GC?

STUDD is the back office your HVAC shop needs but can't afford to staff. Invoicing, AR follow-ups, compliance tracking, and job profitability - running in the background while you're on the jobsite.

The HVAC sub's reality

The problems STUDD was built to solve.

The invoice gap

Ductwork changes and equipment swaps that never get billed.

The architect changes the layout, the GC wants a bigger unit, you add a zone mid-project. The extra work gets done, the crew moves to the next job, and the change order never makes it to paper. STUDD catches it.

The GC slow-pay

Net-30 that quietly becomes net-120.

HVAC subs carry heavy equipment costs upfront. Without automated follow-ups firing on a cadence, your receivables age silently while you're financing the GC's project. STUDD tracks every invoice, every GC, every aging day.

Cover My Ass

One expired EPA cert and you're off the job.

HVAC licenses, EPA 608 certifications, COIs, refrigerant handling permits, W-9s, workers' comp - each with its own renewal date. Miss one and you're pulled from the project. STUDD tracks every document and alerts you before anything lapses.

What changes with STUDD

What your shop looks like after 90 days.

Invoicing

Every job gets billed. Every time.

Templates per GC, per job type. Change orders get captured the same day. Invoices go out on schedule, not when you remember to sit down at the laptop.

AR tracking

You know exactly who owes you what.

Aging reports by GC, automated follow-up emails, and lien-rights timers that fire before you lose leverage. No more wondering if that check is coming.

Cover My Ass

Nothing expires without warning.

Every license, COI, W-9, bond, and certificate tracked in one place. Renewal alerts hit your phone, not a filing cabinet you check once a quarter.

HVAC questions

Things HVAC contractors ask us.

Can my guys in the field use it?: Yes. STUDD is built for phones, not desktops. Your crew can log tickets, attach photos, and update job status from the roof or the mechanical room. You don't need everyone at a computer.
I have different rates for different GCs. Can it handle that?: Yes. Payment terms, billing templates, and follow-up cadences are all set per GC. Your net-30 client and your net-60 client don't get the same treatment.
What about service calls vs. new construction?: STUDD handles both. Service calls, new construction, changeouts, maintenance contracts - each job type can have its own billing template, margin target, and compliance checklist.
Do I need to import everything from QuickBooks first?: No. You can run STUDD alongside whatever you're using now. Most shops start by sending new invoices through STUDD and migrate history over time. No big-bang switchover required.
