Commercial or residential customers: which to lean toward

Your phone rings twice before nine. A homeowner wants a bath fan replaced this week and will pay you when you pack up. A property manager wants pricing on 22 units, wants a certificate of insurance naming her company as additional insured, and pays 45 days after her accounting system accepts the invoice.

Both are real work. The difference is not job size — it is how much money you float, how many people have to agree, and what you prove before you are allowed on site. Most small operations run both, so the question is which one your cash, crew and paperwork are built around, and how much of the other you can carry.

The same top line, two different balance sheets

Take a one-truck operation doing $180,000 a year, once as residential work and once as small commercial. The numbers are illustrative — your ticket and close rate will differ — but the ratio between the columns holds.

That last row is the argument. At $180,000 a year you earn about $493 a day, so every day of collection delay is $493 you have lent the customer — 50 days out is roughly $24,700 of your money funding somebody else's operation for as long as the account lasts. This is how shops go broke on good news: they win the account, buy materials, run payroll for two cycles, and hit the wall before the first check clears. Size a commercial account against the cash you can be without for two months, not the profit on the job.

The estimating row matters too: residential wins come from many short walkthroughs, commercial wins from fewer long documents priced against somebody else's specification, where a missed exclusion is yours to eat.

Who has to say yes, and what they need first

A residential decision happens in a kitchen. One or two people are spending their own money, comparing two or three estimates, deciding partly on whether they trust you. It can close the same day, and the sale is clarity and speed.

A commercial decision is a process wearing a person's face. The facilities contact who wants the work often cannot authorize it. There may be a purchasing rule requiring competitive bids above a dollar threshold, an approval chain above a second one, and a purchase order that has to exist before you show up. An invoice with no PO number does not get argued with. It just sits.

So before you price anything, ask who signs and at what spending limit, whether a PO is required and what has to appear on the invoice, what the payment terms are in days, and whether anyone holds retainage. Those answers tell you more about the account than the walkthrough does.

What commercial buyers ask for that homeowners never do

A homeowner rarely asks to see your insurance. A commercial contract asks first, and the requirements come from their risk department, not your state's minimum:

• A certificate of insurance (COI) with stated general liability limits, the customer named as additional insured, sometimes with a waiver of subrogation.
• Workers' compensation, even if your state lets a solo owner opt out. A statutory exemption does not satisfy a private contract, and many buyers will not accept a signed exclusion.
• A W-9 and tax ID, plus onboarding in a vendor portal, so the customer can set you up for payment and determine any reporting they must do.
• Safety paperwork on larger sites: orientation, OSHA training cards, sometimes an experience modification rating.
• Bonding and prevailing wage on public work — bonds mean a surety reviewing your financials before you can bid, and a published wage rate changes your labor cost on that job.

Sales tax can land differently too: whether labor is taxable, and whether the job counts as repair or capital improvement, can turn on the customer type and on exemption certificates only commercial and nonprofit buyers hand you. Start with is labor taxable, then ask your state revenue department. Lien rights split as well — many states put stricter notice rules on residential property.

Two marketing motions that barely overlap

Residential demand announces itself. A water heater fails, someone searches, and they call whoever is findable and quick — hence the Google Business Profile, the reviews, answering first.

Commercial demand does not arrive that way. Nobody searches for a plumber for a 40,000 square foot building — there is an incumbent and a contact list. You get on the list by asking, and you get work when the incumbent does not show up. Reviews barely move it; three references and a clean COI do. Bids for larger and public work arrive through their own channels: plan rooms and bid platforms, city, county and school district purchasing sites, SAM.gov for federal work.

The realistic first commercial job for your trade

The first one is never the office tower. It is small, repeatable, adjacent to what you already do, and often after hours:

• Service trades — plumbing, electrical, HVAC, locksmith: time-and-materials calls for restaurants, dental offices, salons, then a maintenance agreement with a named straight-time and overtime rate.
• Cleaning and janitorial: one small office or clinic on a nightly schedule.
• Landscaping: maintenance on a strip center or HOA common area, plus snow removal where the season gives you one.
• Painting, flooring, drywall: tenant turnover and make-ready work, high-volume and low-drama.
• Roofing, concrete, framing: as a sub to a general contractor long before you hold a prime contract.

Whichever route fits, the first commercial job's real product is a reference and a payment history you can show the next buyer. Price it to make money, but judge it on the door it opened.

Choose a weight, not a side

Four checks set the ratio:

1. Can you be without 45 to 60 days of a job's cost? If not, take commercial only on short terms or card payment until you can.
2. Is your year lumpy? Contract and service-agreement work smooths a seasonal book better than more residential work does.
3. Do you have crew depth? On a commercial schedule other trades wait on you, and a one-truck delay becomes somebody's claim.
4. Which selling suits you? Residential means winning strangers every week; commercial means keeping a few relationships warm for years.

Then cap concentration. As a rule of thumb, get nervous once one customer passes roughly a quarter of revenue — past that, their payment habits and budget cycle are running your business. If a commercial account grows through that line, the next one you chase should be a different customer, not a bigger job with the same one.

Sending the same price to two audiences

The friction in running a mix is that a homeowner and a facilities manager need the same job described differently. One wants plain language and a clear line between what is included and what is not; the other wants line items that map to their PO, terms on the page, and enough detail to survive an approval chain. With DoneQuote you describe the job once and set the wording and detail for whoever is reading, so the scope and rate you worked out are what goes out — as an estimate, a quote, or a per-unit sheet for 22 units.

The short version

• Same revenue, different cash: at $180k a year, 50-day terms park about $24,700 in receivables against roughly $3,500 residential
• Ask who signs, whether a PO is required and what the terms are before pricing commercial work
• Budget for a COI with named limits, workers' comp with no owner exclusion, a W-9 and EIN, and bonding on public jobs
• Enter through small repeatable work in your trade, and keep any one customer under a quarter of revenue
