Most service businesses start residential because residential is how you get going: someone calls, you fix it, they pay. Then at some point an owner notices that a single property management contract could be worth more than a quarter of homeowner work, and decides to go after commercial.
It usually goes badly at first, and the reason is that almost every habit that makes you good at residential is a liability in commercial sales.
The two businesses are genuinely different
| Residential | Commercial | |
|---|---|---|
| Who decides | The person standing in front of you | Someone you may not have met, on a committee or a budget line |
| What wins | Answering fast, being likeable, being available | Reliability, documentation, insurance, not being a problem |
| Sales cycle | Hours to weeks | Months, often tied to a budget or contract cycle |
| Payment | On completion | Net 30 to net 60, with a PO, through an accounts process |
| Price sensitivity | High at the moment of quoting | Lower — but they will not overpay twice |
| Churn | Gradual and invisible | Sudden, at renewal, with a formal process |
The row that catches people is payment. A business running on same-day residential cash flow that suddenly wins a large commercial contract can find itself in a cash squeeze precisely because it won — sixty days of labour and materials funded out of pocket before the first cheque lands.
Who actually buys
Commercial is not one market. There are four buyers, they behave differently, and the mistake is treating them as one segment called "commercial".
- Property managers — many properties, frequent small urgent jobs, and above all a preference for whoever answers and does not create work for them. The easiest entry point for most residential companies, and the one where speed still wins.
- Facility managers at single sites — a school, a plant, a hospital. Long relationships, real budgets, and a strong preference for a vendor who already knows the building.
- General contractors and builders — project-based, schedule-driven, and unforgiving about delays. They buy reliability on a date.
- HOAs and boards — committee decisions, annual bid cycles, minutes and proposals. Slow, and stickier than anything else once you are in.
Getting in is about being available at the moment of failure
Nobody switches a commercial vendor because a nice proposal arrived. They switch because the current vendor let them down, and at that moment they need someone today.
Which makes the entry strategy less about pitching and more about being findable, credible, and reachable when that happens:
- Take the emergency call that nobody else takes. The Friday evening job at the building whose usual contractor is not answering is the single most common way residential companies get their first commercial account. Do it well, invoice it fairly, and follow up.
- Ask your existing customers where they work. Your homeowner customer is somebody's facility manager, office manager, or landlord. This is the most under-used commercial lead source there is, and it costs a question.
- Be visible to the people who get asked. Property manager associations, local BOMA or IREM chapters, and the informal networks where a manager asks "who do you use for..." — that question is where most contracts actually originate.
- Get on the approved vendor list before there is work. Many organisations cannot hire you in an emergency if you are not already approved. That paperwork is boring, takes weeks, and is the entire reason some companies get the call and others do not.
What they need from you that residential never asked for
Commercial buyers are managing risk, not buying a repair. The things that feel like bureaucracy are the actual product.
- Certificates of insurance, at the limits they require, produced within hours rather than days. A COI request that takes you a week signals what working with you will be like.
- W-9, licences, and vendor onboarding paperwork, kept current and ready to send.
- Documentation of work performed — dates, what was done, photos, who attended. A facility manager has to justify spend to someone else, and your paperwork is their evidence.
- Consistent invoicing with PO numbers. An invoice missing a PO will not be paid, and you will discover this at day forty-five.
- A single point of contact who knows their sites and answers. This is what they are really buying.
Structure the account properly from day one
A commercial account is not a customer record with a company name on it. It is a payer with multiple properties, several contacts, and a contract with dates — and if your system cannot express that, you will be running the relationship out of someone's memory within three months.
Minimum viable structure: one account, many sites, contacts with roles, a named owner on your side, contract start and renewal dates, and every job attached to the correct site. The moment a property manager asks "what did you do at the Oak Street building this year?" you either answer in thirty seconds or you demonstrate exactly why they should keep shopping.
Renewals are the whole game
Commercial revenue is lost at renewal, suddenly, in a process you were not invited to. The protection is unglamorous and almost entirely about not being invisible between jobs.
- 01Know the renewal date and work backwards
Sixty to ninety days out, not the week the notice arrives. By then the alternatives have already been priced.
- 02Bring a year in review
What you did, what you caught early, what it saved. Facility and property managers have to justify vendors internally, and you can hand them the justification.
- 03Check in when nothing is wrong
A quarterly conversation with the person who signs, not just the person who unlocks the door. Accounts are lost by companies who only ever appear when something is broken.
- 04Track the individual, not just the account
Property managers move employers every few years, and they take vendor preferences with them. A manager who liked you and changed jobs is the warmest lead in your database, and nobody follows them.
You do not win commercial accounts with a proposal. You win them on the evening their usual contractor did not answer.
Common questions
How do residential service businesses get commercial clients?
Usually by being available at the moment of failure — the after-hours emergency at a building whose regular contractor is not answering. Beyond that: ask existing homeowner customers where they work, get visible in property manager networks, and complete approved-vendor paperwork before there is work, because many organisations cannot hire an unapproved vendor in an emergency.
How is commercial work different from residential?
The decision-maker is often someone you have not met, the cycle runs months rather than days, payment is net 30 to 60 through an accounts process with a PO, and churn happens suddenly at renewal rather than gradually. What wins is reliability and documentation rather than speed and likeability.
What paperwork do commercial clients expect?
Certificates of insurance at their required limits produced within hours, W-9 and licences kept current, documented work with dates and photos, and invoices carrying the correct PO number. This is not bureaucracy around the service — for a facility manager justifying spend internally, your documentation is the product.
How do I keep a commercial account from being lost at renewal?
Work backwards from the renewal date ninety days out, bring a year in review showing what you did and caught early, check in quarterly with the person who signs rather than the person on site, and track individual managers when they change employers — they take vendor preferences with them.
