Residential field service sells to homeowners one job at a time, with short sales cycles, payment on completion and customers who want a tight arrival window; commercial field service sells to businesses and property managers through contracts, with SLAs, longer payment terms and visits that have to fit the site's operating hours. Both can be profitable. They need different pricing, staffing and scheduling.
Many service companies start residential and add commercial as they grow, or the other way around. The trucks and the trade skills carry over. A lot of the rest doesn't. Treating a commercial account like a big residential customer is one of the more common ways growing companies lose money on work that looked like a win.
This guide compares the two side by side, then covers how to decide on a mix and how to run both from one board. For the wider context, see our field service management guide.
The side-by-side comparison
| Residential | Commercial | |
|---|---|---|
| Buyer | Homeowner, sometimes a landlord | Facilities manager, property manager, procurement |
| Decision maker | Usually the person you're talking to | Often a committee or someone off site |
| Sales cycle | Hours to days | Weeks to months |
| Pricing | Flat rate or per-job quote | Contract rates, bids, often negotiated |
| Payment | Usually on completion | Invoiced, often on net terms |
| Volume per customer | One to a few visits a year | Many sites, many visits, recurring |
| Expectations | Arrival window, communication, cleanliness | Response time, documentation, compliance |
| Contracts | Optional maintenance plans | Service contracts and SLAs are common |
| Access | Homeowner is there or isn't | Site contacts, badges, loading docks, hours |
| Equipment | Smaller, consumer-grade systems | Larger, more complex, sometimes specialized |
None of these are absolute. A small office behaves a lot like a residential customer. A large homeowners' association behaves a lot like a commercial account. But the patterns hold often enough to plan around.
How the money works
Residential: high volume, fast cash
Residential work turns over quickly. A job gets booked, done and paid, often the same day. Average tickets can be high on replacements and lower on repairs. Marketing cost per customer is real, because many homeowners need you once every few years.
The metrics that matter most: average ticket, close rate on replacement estimates, and repeat or maintenance-plan customers.
Commercial: lower margin per hour, more predictable
Commercial customers often negotiate rates, and large accounts know how much work they represent. Per-hour margin can be lower than residential. What you get in exchange is volume and predictability: a contract that sends you to thirty sites four times a year is a capacity plan you can count on.
The catch is cash flow. Commercial customers usually pay on terms. If a large account pays net 45 or net 60, you're financing that work out of your own cash for weeks.
Cash tied up in receivables ≈ monthly commercial revenue × (average days to pay ÷ 30)
That's working capital you need before you take the work. Talk to your accountant about how much your business can carry.
How the schedule works
This is where the two differ most, and where the cost of mixing them shows up.
Residential scheduling: tight windows, many stops
Homeowners take time off work or rearrange their day for you. The arrival window is the product. A narrow window that you actually hit builds trust; a four-hour window you miss loses the customer. Residential days often have more stops and more driving between them.
The scheduling problem is feasibility: can the truck really get from the 10:00 job to the 12:00 job? Our article on why arrival windows are so long explains how uncertainty about the drive leads companies to pad windows.
Commercial scheduling: deadlines, access and duration
Commercial visits are shaped by different constraints:
- Site hours. A restaurant may only allow work before 10:00 a.m. An office may require after-hours visits. A hospital may have strict access windows.
- SLA deadlines. A P1 call has to be reached within the contracted time, which can push other work. See the SLA guide.
- Longer visits. Preventive maintenance on a large building can take most of a day, and multiple technicians.
- Multi-site routes. A contract with twenty locations is effectively a route you'll repeat every quarter.
- Documentation. Commercial customers often want service reports, photos and readings on every visit.
Mixing both on one board
When residential and commercial share technicians, each type of work makes the other harder to schedule. A P1 commercial call can wreck a residential day full of promised windows. A long PM visit blocks a technician who could have done four residential repairs.
Ways companies handle it:
- Separate crews. Some technicians only do commercial, others only residential. Simplest, but it splits capacity and can leave one crew idle while the other is overloaded.
- Reserved capacity. Shared technicians with a fixed block of time held for commercial emergencies each day.
- Day-type scheduling. Certain days or half-days are commercial, the rest residential.
- Territory split. Commercial accounts in one zone are covered by the technicians already working there. See zone scheduling.
Whatever you choose, the key question at booking is the same for both: can a qualified technician get there in time, given where they'll be? CrewLink checks feasibility before a slot is offered, using travel from the previous job rather than from the shop. That matters most on a mixed board, where one long commercial visit can push every residential window after it.
Staffing and skills
Commercial equipment is often larger and more varied than residential. A commercial kitchen equipment technician, a fire protection inspector or a technician working on rooftop units needs different training and sometimes different certifications than a residential service technician.
Plan for:
- Certification requirements set by the customer, the equipment manufacturer or local code. Confirm them with the customer and the relevant authority before you bid.
- Insurance requirements. Commercial contracts often require specific coverage levels and certificates. Your insurance broker can tell you what you need.
- Soft skills. Residential technicians talk to homeowners in their kitchens. Commercial technicians deal with site managers, security desks and maintenance staff. Both need communication skills, but different ones.
How to decide on a mix
There's no correct ratio. Ask these questions about your own business.
What does your cash position allow?
If you can't comfortably carry 30 to 60 days of receivables on a large account, big commercial contracts will strain the business no matter how profitable they look.
Where is your capacity idle?
Residential demand is often seasonal and concentrated at certain times of day. Commercial PM work can be scheduled into slow seasons and off-peak hours. If you have predictable slow periods, commercial maintenance contracts can fill them. The capacity planning guide shows how to see where those gaps are.
How concentrated is your risk?
One commercial account worth a quarter of your revenue is a risk. If it leaves, you've lost a quarter of your business at once. Residential revenue is spread across thousands of customers. A common rule of thumb is to avoid letting any single customer get too large a share, but the right limit depends on your situation.
What does your team want?
Some technicians prefer the variety and customer contact of residential work. Others prefer the larger equipment and repeat sites of commercial. Forcing the wrong mix on your crew is a retention risk. See the technician retention guide.
Adding commercial work to a residential company
If you're making the move, a few practices help:
- Start with small commercial. Small offices, retail stores and restaurants are closer to residential in expectations and payment.
- Price for the real cost. Include documentation time, site access delays, travel to multiple sites and payment terms. The field service pricing guide covers how.
- Write SLAs you can keep. Set response times from your real drive times, not the customer's wish list.
- Track commercial separately. Report margin, on-time arrival and SLA compliance for commercial work on its own line so it doesn't hide inside residential averages. The reporting guide shows how.
- Get contracts reviewed. Commercial service contracts include liability, indemnity and payment clauses that deserve an attorney's eye.
Industries differ here too. HVAC, plumbing and electrical companies often run both; property maintenance and snow removal companies lean commercial by nature.
What to take away
- Residential means short sales cycles, payment on completion and tight arrival windows. Commercial means contracts, SLAs, net terms and site constraints.
- Commercial work can be lower margin per hour but more predictable. Check how much cash net terms will tie up before you sign.
- Mixing both on one board is the hard part. Use separate crews, reserved capacity, day types or territory splits.
- Decide your mix from cash position, idle capacity, customer concentration and what your technicians want.
- Track commercial work separately and have contracts reviewed by an attorney.
Common questions
What is the difference between commercial and residential field service?
Residential service works for homeowners on individual jobs, usually paid on completion with a promised arrival window. Commercial service works for businesses and property managers, often under contracts with SLAs, net payment terms, documentation requirements and site access constraints.
Is commercial service work more profitable than residential?
Not automatically. Residential work often earns more per hour, while commercial work offers volume and predictability but with negotiated rates and slower payment. Profitability depends on your pricing, costs, cash position and how well you schedule each type.
Can one company do both commercial and residential service?
Yes, many do. The challenge is scheduling, since commercial emergencies and long maintenance visits can disrupt residential appointment windows. Separate crews, reserved capacity or day-type scheduling help keep both on track.
How do I start getting commercial service accounts?
Start with small commercial customers like offices, retail and restaurants, which are closer to residential in expectations. Price for documentation, access and payment terms, write SLAs you can keep, and have contracts reviewed before signing.
What payment terms do commercial customers usually expect?
Many commercial customers pay on invoice terms, such as net 30 or longer, rather than on completion. Terms vary by customer and are often negotiable. Plan the cash you'll need to carry before taking on large accounts.
