HVAC technicians spend too much time sitting in hot attics or noisy mechanical rooms writing messy paper receipts. Invoice for Trades was designed for speed, so you can quote, invoice, and get paid without ever opening a laptop:
- Separate labor from expensive equipment: Cleanly break down condenser units, thermostats, coils, and refrigerant from hourly technician time.
- Keep track of unpaid invoices: Never let a commercial client's net-30 slip through the cracks. Filter instantly by Draft, Sent, Paid, and Overdue.
- Document refrigerant and parts usage: Log the refrigerant type, quantity, and parts used on each job for accurate billing and warranty records.
- No desk required: Tap, generate PDF, and share straight to WhatsApp or email right from your Android phone before you start your engine.
How HVAC Techs Invoice a Job in Under 2 Minutes
The workflow is built for a service van, not an office. Here's how it works:
- Step 1 — Add the customer and site: Enter the name, address, and system reference once. The app remembers them for seasonal maintenance visits.
- Step 2 — Pick parts and labor from your saved list: Tap from your saved equipment and hourly rates — compressors, thermostats, coils, refrigerant, diagnostic fees — and the app calculates the subtotal.
- Step 3 — Convert estimate to invoice: If you already sent an estimate, convert it in one tap. All line items carry over automatically.
- Step 4 — Send and get paid: Export as PDF and share via WhatsApp, SMS, or email while you're still on site. Track paid vs. unpaid in the app.
