Moving into commercial work: it is not bigger residential, and the cash gap is what breaks companies

Pricing commercial work without losing money

The most common error is quoting a commercial job at residential rates plus a bit. The costs that residential pricing does not contain:

• The cost of money. Being paid at 60 days on a $28,000 job means carrying materials and payroll for two months. At any realistic cost of capital, that is a real expense and it belongs in the price.
• Administrative load. Purchase orders, work order systems, portal submissions, lien waivers, certified payroll on some jobs. Commercial clients frequently require entry into their own systems, and someone has to do that work.
• Access and coordination time. Waiting for a tenant, badge sign-in, meeting a building engineer, working around occupancy. Frequently 20% to 40% more hours on site for the same scope.
• Compliance overhead. Insurance riders, safety programs, drug testing, background checks. Fixed costs that need to be spread across commercial revenue.

Worked example. A repair that takes 3 hours residentially, billed at $145 an hour, is $435 plus materials. The same scope in an occupied office building takes 4.6 hours including access and coordination, requires a portal submission taking 25 minutes of office time, and is paid in 52 days. At the same nominal rate the job produces $667 in 4.6 hours — an effective $145 an hour with unpaid admin time and two months of financing attached. Priced correctly at a commercial rate of $178 with a $95 administrative line, it produces $914, which is what makes the account worth having.

Who actually buys, and how they buy

• Property management companies. The highest-volume buyer in this category. One relationship can carry a dozen buildings, and they switch vendors over responsiveness rather than price. They want a single point of contact, fast dispatch and clean documentation.
• Facility managers at owner-occupied sites. Schools, hospitals, manufacturers, churches. Longer sales cycles, budget calendars, but extremely sticky once established.
• General contractors. Project work rather than service work, with retainage, schedules and payment tied to draws. A different business again, and worth entering deliberately rather than accidentally.
• National facility maintenance networks. Volume without sales effort, at compressed rates, heavy documentation and slow payment. Useful for filling capacity; dangerous as a primary channel.
• Small business owners directly. Restaurants, retail, offices. Behaves much more like residential — decisions are fast, payment is prompt, and it is the easiest entry point.

How to enter without betting the company

The failure pattern is dropping residential work to chase a large commercial account, then discovering the cash gap. A safer sequence:

• Start with small business direct. Restaurants and retail pay quickly, decide fast and give you commercial references without the terms exposure.
• Add one property management company, not three. Learn their systems, their documentation and their payment behavior on a small number of buildings before scaling.
• Cap commercial at a share of revenue until cash flow proves out. Many operators use 30% as a working ceiling during the first year.
• Keep the residential engine running. It pays weekly and it funds the receivables. Companies that shut it off to focus on commercial usually discover why it mattered around month four.

Twelve months, measured

Residential electrical contractor, $1.4 million in revenue, six technicians, no commercial work.

• Month 1: insurance reviewed and raised to typical commercial requirements; certificates and additional insured endorsements arranged. Cost: $4,100 a year.
• Month 2: commercial rate set 23% above residential, with a separate administrative line item.
• Month 3: eight small businesses signed for service work — three restaurants, two retail, three offices.
• Month 6: first property management company added, four buildings. Payment averaged 47 days.
• Month 12: commercial at 28% of revenue, total revenue $1.86 million, and a line of credit opened specifically to bridge receivables.

The line of credit is the part owners skip and the part that made this work. Commercial receivables averaged $91,000 outstanding at any moment by month twelve — money that was earned, uncollected and still had to appear in payroll every Friday.

The second lesson came from the property management relationship: the four buildings produced steady work, but two of the first three invoices were rejected for incorrect submission format and sat for an extra month. Learning a client's system is a real cost that only appears once you are inside it.

Documentation is the product

Residential customers judge the work. Commercial customers judge the paperwork, because the paperwork is what protects them.

• Before and after photos on every work order. The property manager forwards them to the owner. You are producing their evidence, not yours.
• Clear line-item invoicing tied to the work order number. An invoice that cannot be matched to an authorization sits unpaid indefinitely, and nobody calls to tell you.
• Written recommendations for deferred work. This is where the additional revenue lives, and property managers need it in writing to request budget.
• Response time reporting. If you can show it, show it. It is what renews the contract.

Prospecting property managers without becoming noise

Property managers are approached constantly and have learned to ignore almost all of it. They are also genuinely underserved, because most vendors who reach them are unreliable in ways that only appear later. Four approaches get through.

• Lead with emergency availability, not with price. A property manager's worst day is a flooded unit at 6 p.m. on a Friday with no vendor answering. Being the number that answers is worth more than any rate, and it is the only promise they will actually test early.
• Ask to be the backup, not the primary. They already have someone, and displacing an incumbent from the front is a slow argument. Being second on the list costs them nothing to agree to — and the first time the incumbent does not answer, you become the primary by default. This is the single most effective entry into the category.
• Find them where they gather. Regional apartment associations, building owner groups and property management chapters hold events attended by exactly the people you need, and vendors are usually welcome. One relationship formed there outperforms a hundred cold emails.
• Give them something for their own reporting. A simple building condition assessment, done free on one property, produces a document they can take to an owner requesting budget. It positions you as someone who makes their job easier rather than someone selling to them, and it frequently generates the first paid work directly.

One thing to avoid: quoting a low introductory rate to win the account. Property management contracts are rebid on price once the rate is established, and a vendor who entered cheap has no room to correct later. It is better to enter at a sustainable rate with better availability, because availability is what they actually lose sleep over and price is what they negotiate out of habit.

A final point on documentation that owners underestimate: it is also your protection. In residential work, a dispute is a conversation between two people who were both there. In commercial work, a dispute is resolved months later by someone reading a file — often a person who never saw the building and is deciding between your invoice and a tenant's recollection. Photographs with timestamps, a signed or acknowledged work order, and a written scope are what make that file favorable to you. Companies that treat paperwork as an administrative chore rather than as evidence tend to learn this on the first significant disagreement, and the lesson is expensive.

Five mistakes that make commercial expansion fail

• Using residential rates. They do not contain access time, admin or the cost of waiting 60 days.
• Entering without a credit facility. Growth in commercial consumes cash before it produces it.
• Taking three property management companies at once. Each has different systems, and learning them simultaneously guarantees rejected invoices.
• Dropping residential to focus. Residential pays weekly and funds the receivables.
• Ignoring the submission requirements. An invoice in the wrong format is not late — it is invisible.

Five numbers to watch during the transition

• Days sales outstanding, split by segment. The number that reveals whether commercial is funding or draining you.
• Effective hourly rate on commercial jobs. Including access time and admin, not the quoted rate.
• Commercial as a percentage of revenue. The exposure ceiling during year one.
• Invoice rejection rate. A direct measure of how well you have learned each client's system.
• Revenue per property management relationship. Tells you which ones deserve more attention and which are consuming capacity.

Commercial work is genuinely better business once the structure is in place: larger jobs, repeat volume, buyers who plan. But it is bought on documentation and paid on someone else's calendar, and a residential company that expands into it without a higher rate, a credit line and the patience to learn one client's systems at a time will end up busier, larger and shorter on cash than it was before.

Frequently asked questions

How is commercial work different from residential for a service business?

Four differences matter, and none of them are about job size. The buyer is not the user: in residential the person who feels the problem writes the check, while in commercial a property manager buys on behalf of an owner for tenants who complain to them, so their incentives are documentation, predictability and not being blamed — not lowest price and not fastest fix. Payment terms are the business: net 30 is standard, net 45 and net 60 are common, and the invoice does not begin aging until it has been correctly submitted with the right documentation. Insurance and compliance requirements are real, including certificates with specific limits, additional insured endorsements, sometimes waivers of subrogation, background-checked technicians and safety documentation. And scheduling is constrained by after-hours access, tenant coordination, building procedures and noise restrictions, so work that takes three hours in a house takes six in an occupied building.

How should you price commercial service work?

Not at residential rates plus a bit, because residential pricing does not contain four costs. The cost of money: being paid at 60 days on a $28,000 job means carrying materials and payroll for two months, which at any realistic cost of capital is a real expense. Administrative load: purchase orders, work order systems, portal submissions, lien waivers and sometimes certified payroll, all of which someone has to do. Access and coordination time, frequently 20% to 40% more hours on site for the same scope. And compliance overhead — insurance riders, safety programs, background checks — that has to be spread across commercial revenue. Worked example: a repair taking 3 hours residentially at $145 an hour bills $435, while the same scope in an occupied building takes 4.6 hours, requires 25 minutes of portal submission and is paid in 52 days. At a commercial rate of $178 with a $95 administrative line, it produces $914 — which is what makes the account worth having.

How do you get property management companies as clients?

Four approaches get through to a buyer who is approached constantly. Lead with emergency availability rather than price, because a property manager's worst day is a flooded unit at 6 p.m. on a Friday with no vendor answering, and being the number that answers is worth more than any rate. Ask to be the backup rather than the primary — they already have someone, displacing an incumbent is a slow argument, and being second on the list costs them nothing to agree to, after which the first missed call makes you primary by default. Find them where they gather, at regional apartment associations, building owner groups and property management chapters, where one relationship outperforms a hundred cold emails. And give them something for their own reporting, such as a free building condition assessment they can take to an owner requesting budget. Avoid quoting a low introductory rate: these contracts get rebid on price, and a vendor who entered cheap has no room to correct.

How much commercial work should a residential company take on?

Many operators use 30% of revenue as a working ceiling during the first year, and the constraint is cash rather than capacity. The failure pattern is dropping residential work to chase a large commercial account and then discovering the cash gap. A safer sequence is to start with small business direct — restaurants, retail and offices pay quickly, decide fast and give you commercial references without terms exposure; then add one property management company rather than three, learning their systems, documentation and payment behavior on a small number of buildings; cap commercial revenue until cash flow proves out; and keep the residential engine running, because it pays weekly and it funds the receivables. In one electrical contractor that reached 28% commercial in a year, commercial receivables averaged $91,000 outstanding at any moment — money earned, uncollected, and still required in payroll every Friday.

Why do commercial invoices go unpaid?

Usually because they were never properly received, not because the client is refusing. An invoice that cannot be matched to a work order or purchase order number sits indefinitely and nobody calls to tell you. In one company entering the category, two of the first three invoices to a property management client were rejected for incorrect submission format and sat an extra month — learning a client's system is a real cost that only appears once you are inside it. Beyond format, commercial customers judge the paperwork rather than the work, because the paperwork is what protects them: before and after photos on every work order, which the property manager forwards to the owner; clear line-item invoicing tied to the authorization number; written recommendations for deferred work, which is where additional revenue lives and which they need in writing to request budget; and response time reporting, which is what renews the contract.
