HVAC invoicing has to handle the full price spectrum: a $145 service-call diagnostic, an $8,000 install down payment, a $35/month annual maintenance plan. All from the same CRM. Smarfle generates invoices from completed work orders in 30 seconds, auto-charges saved cards for maintenance plans, and routes big install deposits to ACH for low fees. Cashflow stops being your weekly stress.

Why generic invoicing software fails hvac owners

Generic invoicing tools weren’t built for hvac. Smarfle was.

Generic invoicing software

What everyone else gives you

  • QuickBooks invoicing requires manual data entry from paper work orders
  • No way to save customer cards for future auto-charge on maintenance plans
  • Big install deposits require check-by-mail. 5-7 day delay before crew dispatch
  • Overdue invoices need a Friday-afternoon Excel session to track + chase
  • PDF templates are generic QuickBooks branding. Looks unprofessional next to competitors' branded invoices

Smarfle for HVAC

Built for your actual workflow

  • One click pulls labor + parts + refrigerant + service call fee from the completed WO into a draft invoice
  • Stripe Customer + saved payment method per HVAC client. Annual plan auto-charges off-session without owner intervention
  • Pay Now link supports ACH (0.8% capped at $5). $8k deposit lands next business day, crew dispatched next morning
  • Auto-flip to Overdue past due date + Aging Report shows 0-30 / 30-60 / 60+ buckets. Bulk reminders in one click
  • Branded PDF with your logo, address, payment terms, per-org invoice prefix (e.g. AIRPRO-00142 instead of INV-00142)
Step-by-step

How hvac invoicing works in Smarfle

From the first touch to the closed loop. No missing pieces.

  1. 1

    Tech completes the service call / install / tune-up

    Job complete from the field. Tech logs hours, parts used (filters, capacitors, refrigerant lbs), captures before/after photos + customer signature on their phone.

  2. 2

    Invoice pre-fills from the work order in one click

    Tech or office taps Generate Invoice. Smarfle pulls labor hours at the configured rate, parts with markup applied, refrigerant per lb, service call fee, expenses. Reviewer hits Send.

  3. 3

    Customer gets email + SMS with Pay Now link

    Branded PDF invoice attached to email. SMS includes Pay Now link. Customer pays card or ACH from their phone. Auto-charge if they're on a maintenance plan with saved card.

  4. 4

    Stripe webhook auto-marks paid + sends receipt

    Customer pays. Stripe fires the webhook. Smarfle flips invoice to Paid + auto-sends receipt to customer + drops a confirmation in your inbox + in-app notification.

  5. 5

    Annual maintenance plans auto-charge each year

    Customer's saved card auto-charges on the anniversary date. They get a charge notification + new invoice PDF + their tune-up gets scheduled automatically. Year-over-year retention without manual chase.

  6. 6

    Overdue + aging report keeps AR clean

    Past-due invoices flip to Overdue on cron. Aging report shows 0-30 / 30-60 / 60+ buckets. Workflow automation fires reminder emails on Day 7, 14, 30. AR drops from 30+ days average to 10-12.

Where hvac invoicing breaks down

The friction every hvac owner recognizes.

✕

Service call payment chased for 30 days after the job

Tech finishes the no-cool repair, customer says 'send me the bill', invoice goes out next morning, payment 30 days later. Manual invoicing + no Pay Now link means cash flow on service work is brutal.

✕

Install deposit takes a week to land: crew sits idle

$8k furnace install needs 50% deposit before crew dispatch. Without ACH or card link in the deposit invoice, customer writes a check, mails it, it clears 5-7 days later. Crew + materials are sitting around in the meantime.

✕

Annual maintenance plan billing forgotten in year 2

Customer signed up for an annual tune-up plan. Year 1 you invoiced manually. Year 2 you forgot. Lost $300/customer/year × every plan customer who slipped through.

The math for hvac owners

AR cycle drops from 30+ days to 10-12 days

Same-day invoicing + Pay Now links + auto-charge on maintenance plans collapse the time between job-done and payment-in-bank. For an HVAC business doing $300k/year in service work, going from 30-day to 12-day AR frees up ~$15k of working capital permanently.

HVAC Invoicing Software CRM questions

Tech finishes the job, taps Generate Invoice from the mobile WO, the invoice goes to the customer's phone via SMS with a Pay Now link. Customer pays from their phone before the tech drives away. No 'send me the bill' chase, no NET-30 wait.
Yes. Set up the maintenance plan as an annual recurring service. Customer's card saves on first payment, auto-charge runs off-session on the anniversary date. New invoice generates automatically + customer gets a renewal notification 14 days before charge.
Pay Now link supports both card + ACH. For deposits over $1k, ACH is 0.8% capped at $5 per transaction. That's $5 vs $145 in card fees on a $5k deposit. Customer chooses card or ACH; we default to ACH for $1k+ to encourage savings.
Mark warranty line items as $0 with description 'Warranty service. Covered under [warranty name]'. Customer sees the work was done + that it was covered. Keeps invoices transparent + your warranty obligations documented for future reference.
Yes. Tech logs lbs of refrigerant added on the WO mobile app. Smarfle calculates the refrigerant line item at your configured per-lb rate + applies it to the invoice. Per-customer history is available for warranty claims + future system diagnostics.
Create the install as a project with milestone WOs (Deposit → Phase 1 → Phase 2 → Final). Each milestone is a separate invoice tagged to the project. Customer's saved card auto-charges with one click per milestone. Project-level reports show billed vs collected.
