Getting paid shouldn’t be the hardest part of the job. But for too many HVAC contractors, it is. Chasing invoices, waiting for checks, dealing with bounced payments — it’s a time suck that technology solved years ago. Here’s how to set up payment processing that gets you paid fast. If you’re exploring this area, our Best QuickBooks Alternatives for HVAC and Service guide covers it in detail.
Built-In FSM Payment Processing

Every major field service platform offers payment processing. This is the easiest option because it’s already integrated — invoices created in the app can be paid instantly.
Housecall Pro Payments
Rate: card rates “as low as 2.59%” and 1% on bank payments, per Housecall Pro’s pricing page (checked Oct 29, 2026); your rate depends on plan and volume Features: Card reader for on-site swipes, online payment links in emailed invoices, auto-charge on file Payout: 1-2 business days
Jobber Payments
Rate: Confirm current card and ACH rates on Jobber’s pricing page; we have not verified them Features: Card and ACH processing, on-site and online, automatic payment reminders Payout: 1-2 business days Standout: An ACH option is worth using for large invoices (installs, commercial)
ServiceTitan Payments
Rate: Custom quote; ServiceTitan does not publish prices Features: Card processing, financing integration (GreenSky, Wisetack), customer-facing payment portal Payout: 1-2 business days Standout: Financing integration lets customers finance large purchases instantly
Dedicated Payment Processors
If you process high volumes and want lower rates, dedicated processors can save money:
Square
Rate: Per Square’s fee page (checked Oct 29, 2026): online and invoice cards are 3.3% + 30c on the Free plan and 2.9% + 30c on Plus and Premium; ACH is 1% ($1 minimum) Why consider: Invoices are included on the Free plan. Works alongside your FSM (but doesn’t integrate as seamlessly).
Stripe
Rate: 2.9% + $0.30 for domestic cards, 0.8% capped at $5 for ACH, per Stripe’s pricing page (checked Oct 29, 2026) Why consider: Best ACH pricing. Excellent API for custom integrations. Popular for subscription billing (maintenance agreements).
Clearent
Rate: Quote-based; no rate verified Why consider: A candidate for high-volume shops that want to negotiate. Dedicated merchant account with personalized support.
Heartland
Rate: Interchange-plus pricing; no rate verified Why consider: Transparent pricing structure, strong in the home services vertical. Worth a quote if you process high volume.
Fee Comparison on $40K/Month Card Volume
Illustrative example using only published rates, assuming 200 card payments averaging $200 (a $0.30 fixed fee adds $60):
| Processor | Rate | Monthly Cost |
|---|---|---|
| Stripe | 2.9% + $0.30 | $1,220 |
| Square (Plus/Premium, online/invoice) | 2.9% + $0.30 | $1,220 |
| Square (Free, online/invoice) | 3.3% + $0.30 | $1,380 |
| Housecall Pro (best case “as low as”) | 2.59% | $1,036 before any fixed fee |
Clearent, Heartland and ServiceTitan are quote-based, so request quotes and compare them against these figures using your own volume. A dedicated processor is worth it if you process this volume and the quote beats your built-in rate; it is not worth the integration hassle if you process less.
Financing: The Game-Changer for Big Tickets
For system replacements ($5,000-$15,000), offering financing dramatically improves close rates. Customers who can’t afford $10,000 upfront can afford $150/month.
GreenSky
Most popular financing provider for home services. Offers promotional rate options. Integrates with ServiceTitan. Funds you within days while the customer pays over time.
Wisetack
Newer, tech-forward financing. Clean customer experience — customer applies on their phone during the sales presentation and gets approved in seconds. Integrates with Housecall Pro, ServiceTitan, and Jobber.
Synchrony
Large financing provider with home improvement-specific products. Higher approval rates than some competitors. Good for customers with imperfect credit.
The Financing Impact
Shops offering financing close 15-25% more replacement sales. A customer who would have said “let me think about it” to a $10,000 quote says yes when they see $175/month with 0% interest.
If you sell 5 replacements/month and financing closes 2 additional sales, that’s $15,000-$20,000 in additional monthly revenue. The financing provider takes a fee, so get it in writing, but you can still come out well ahead.
On-Site Collection Best Practices
The Ask
“I can process your payment right here — saves you from dealing with a bill later. Card or check?”
Not: “Would you like to pay now?” (too easy to say no) Not: “Do you have a card?” (assumes they might not) Not: silence (hoping they’ll offer to pay)
The definitive statement followed by a choice (card or check) is the most effective approach. 90%+ of customers pay on the spot when asked this way.
Card Reader Setup
Every tech should have a card reader paired with their phone. Check reader costs with your FSM or processor. Process the payment before leaving the driveway.
For Checks
Accept checks for in-person payment but encourage cards. Cards clear faster, don’t bounce, and are recorded automatically in your system. If they pay by check, photograph it and record the payment in your FSM immediately.
For Large Invoices
Discuss payment before starting work on large repairs. “The repair is $2,400. We can process a card today, or I can send you an invoice with payment options. Would you also like to hear about our financing?” Set expectations upfront.
Cash Flow Impact
Without on-site collection:
- Average days to payment: 25-35 days
- Outstanding receivables on $60K/month revenue: $50,000-$70,000
- Bad debt (uncollectable): 2-3% = $1,200-$1,800/month
With on-site collection + automated invoicing:
- Average days to payment: 3-5 days
- Outstanding receivables: $6,000-$10,000
- Bad debt: under 0.5% = $300/month
Cash flow improvement: $40,000-$60,000 permanently returned to your bank account. That’s money for payroll, marketing, equipment, and growth.
The Bottom Line
Use your FSM’s built-in payment processing unless you process $30K+/month in cards and the savings from a dedicated processor justify managing a separate system. Add financing (Wisetack or GreenSky) for replacement sales. Train every tech to collect payment on-site.
There is no separate payments software to buy (it is built into your FSM subscription). The cash flow improvement is transformational. Stop sending invoices and hoping for checks. Get paid today.
