Commercial or residential customers: which to lean toward

Choose residential or commercial work by comparing payment timing, approval steps, insurance requirements and the capacity needed to deliver. Commercial accounts may offer repeat work, but you need enough cash to carry their payment terms. A mix can work if you price and schedule each account on its actual terms.

Compare cash tied up and estimating time

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 — and none of the ratios is a benchmark.

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.

Identify the buyer and approval process

A residential decision may involve one or more owners. 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.

Commercial approval may involve several people. 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.

Confirm commercial insurance and onboarding requirements

Read the buyer's requirements before pricing. Commercial contracts can ask for coverage and documentation beyond legal minimums:

• Evidence of insurance: a certificate of insurance (COI), plus required additional-insured or waiver-of-subrogation endorsements. A COI alone does not amend coverage; ask your agent to check the actual policy.
• 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 where the solicitation requires them. Federal construction has bond requirements with exceptions; state and local contracts have their own rules. Obtain the applicable wage determination before costing labor.

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 the applicable exemption documentation. Start with is labor taxable, then ask your state revenue department. Check notice and lien rules for the property and your contract role separately.

Find residential and commercial prospects

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 buyers may use a different process. A facilities manager may use an approved-vendor list as well as searches and referrals. Ask how to join the list and which references and insurance evidence they need. 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

A practical starting point is small work close to what you already do. Confirm any after-hours requirements:

• 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 customer mix your business can support

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? Check whether proposed recurring work falls in your quiet periods.
3. Do you have crew depth? On a commercial schedule other trades wait on you, and a delay can affect the wider project.
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. In DoneQuote, you can describe the scope and edit the resulting quote letter and line descriptions for the reader. Use quantities and descriptions to show per-unit work where needed. Review the wording, scope and prices before sending, and use any forms the buyer requires.

The short version

• In the even-billing example, $180k annual revenue and 50-day collection create about $24,700 average receivables; seven days creates about $3,500
• Ask who signs, whether a PO is required and what the terms are before pricing commercial work
• Confirm insurance endorsements, workers' comp requirements, tax paperwork and any bond before bidding
• Start with manageable work in your trade and set a customer-concentration limit your business can tolerate
