How this industry scored
| Measure | Weight | Score (0–100) | Why |
|---|---|---|---|
| Processing volume per merchant | 30% | 84 | Invoices commonly $500 to $1,500 with high job frequency. |
| Acquisition through search | 20% | 92 | The strongest commercial search demand in the study. |
| Expected retention | 20% | 70 | Field service software owns workflow; payments can move. |
| Fit for recurring billing | 20% | 55 | Maintenance plans exist but most revenue is job based. |
| Risk profile (higher is safer) | 10% | 72 | Deposits on unstarted work create some dispute exposure. |
The overall opportunity score is the weighted average of these five measures.
Market size and merchant population
Plumbing, heating and air-conditioning contractors are tracked by the US Census Bureau under NAICS 23822, and IBISWorld covers HVAC contractors as a large, steadily growing industry. The merchant population is enormous and dominated by small owner-operated firms.
Confidence 70%
How money actually moves
Invoices are large — commonly several hundred to a few thousand dollars — and are increasingly paid by card or by a payment link sent after the job. Maintenance agreements introduce a modest recurring component but most revenue remains job based.
Confidence 68%
Modelled platform revenue per merchant
Modelled on the Growth plan at $99 a month plus a 0.60% platform fee. Stripe processing is charged separately by Stripe.
| Scenario | Monthly card volume | Platform revenue per year | Over three years |
|---|---|---|---|
| Conservative | $35,000 | $3,708 | $11,124 |
| Base case | $75,000 | $6,588 | $19,764 |
| Aggressive | $150,000 | $12,588 | $37,764 |

Search and AI answer opportunity
This vertical has the highest commercial search volume in the study for payment-related queries, including invoice payment links, deposits and financing. It is also the most expensive to buy, which favours a content and AI-answer strategy over paid acquisition.
Confidence 72%
Risks and objections
Deposits collected before work begins are a recognised chargeback risk. Field service management platforms already bundle payments and have deep workflow lock-in that a payments-only product does not.
Confidence 68%
Our recommendation
Recommended for acquisition efficiency. The category is enormous and search-led, which fits the content strategy, but repeat purchase is seasonal and switching costs are lower than clinical verticals.
- Sales difficulty
- Easier — owner is the buyer and responds to search and paid demand
- Retention
- Moderate — job-based work means less lock-in than clinical or tuition billing
- Risk
- Moderate — deposits on unstarted work create dispute exposure
