Commercial vs. residential work: choosing your mix

The real difference is who pays and how

For most home service trades, the work itself is similar whether the customer is a homeowner or a property manager. A furnace is a furnace and a lawn is a lawn. What changes is the buyer, the decision process, the payment terms and the risk. Residential customers decide quickly, pay on completion and rarely represent a large share of revenue individually. Commercial customers decide through procurement or a manager, pay on invoice terms, and can represent a large share of revenue on their own.

Neither is better in general. The right mix depends on your trade, your cash position, your staff and what you want the business to look like in five years.

What drives residential demand

Residential demand is broad because most homes are owner-occupied. The US homeownership rate was 65.5% in the third quarter of 2026^[1]. Owners pay for upkeep themselves, and regular maintenance was the top planned home project for US homeowners in Angi's survey, at 32%, ahead of interior painting at 20%^[2].

Some residential work is driven by events rather than plans. In 2023, 5.3% of insured US homes had a homeowners insurance claim^[4], and storm and water damage drive bursts of roofing, restoration and repair work. Those bursts are profitable but unpredictable, so they work best on top of a steady base of maintenance and repair customers.

What drives commercial demand

Commercial work comes from property managers, facility managers, business owners, institutions and general contractors. It includes recurring maintenance contracts, repair calls on service agreements and project work on new construction or renovation. Recurring maintenance is the most stable; new construction is the least.

Construction-linked work follows the building cycle. US housing starts ran at a seasonally adjusted annual rate of 1,221,000 in September 2026, 7.4% below September 2025^[3]. A contractor that relies on builders for install work feels that kind of decline within months. Rental properties are a middle ground: they are residential buildings, but the buyer is a property manager behaving like a commercial customer.

Side-by-side comparison

Payment terms change your cash needs

The biggest practical difference is when money arrives. A residential job is often paid before the truck leaves. A commercial job is invoiced, approved and paid on terms, sometimes after the client's monthly payment run. Construction contracts may also hold back retainage until the project closes. Your payroll does not wait for any of that.

Public clients are more predictable than many private ones. Treasury's guidance says that when a vendor submits a proper invoice, a federal agency must pay it on time, and in most cases owes interest when it pays late^[5]. Many states and cities have similar prompt payment rules. Private commercial clients set their own terms, so negotiate them before you start the work.

• Price commercial work to cover the cost of carrying the receivable for the payment term.
• Invoice the day work is completed, with every document the client needs to approve it.
• Track days to payment by client and raise the issue at the first late invoice, not the third.
• Know your state's lien notice deadlines for construction-related work.

Staffing for each side

Residential technicians are also your sales force: they explain options in the customer's kitchen and earn reviews. Commercial technicians need to work in occupied buildings, follow site safety rules, coordinate with facility staff and complete paperwork clients rely on for their own compliance. Some technicians thrive in both settings; many prefer one.

If commercial work grows, consider a dedicated lead technician or crew, with its own schedule. Mixing urgent commercial calls into a residential schedule is a common cause of late arrivals on both sides.

Marketing differs on each side

Residential marketing is mostly about being found and trusted at the moment of need: local search, reviews, a phone that is answered, a website that works on a phone, and referrals from past customers. Commercial marketing is mostly about relationships built before the need: introductions to property and facility managers, prequalification with general contractors, references from similar buildings and a reputation for showing up on time with the paperwork done.

• Residential: invest in review requests after every paid job, fast call answering and maintenance reminders to past customers.
• Commercial: keep a short capabilities sheet, a current certificate of insurance and three references ready to send the same day.
• Both: track where every booked job came from, so marketing spend follows results rather than habit.

Managing concentration risk

A single commercial account can be a large share of a small company's revenue. Losing it, or having it pay late for three months, can hurt more than losing a hundred residential customers. Set a rule, such as no single account above a fifth of revenue, and review the largest accounts quarterly.

• List your top ten customers by revenue each quarter and calculate their combined share.
• Add a second contact at every large account, so a manager's departure does not end the relationship.
• Renew contracts early and in writing, and know each contract's termination notice period.
• Keep enough residential demand that losing your largest account would be painful, not fatal.

Questions to ask before taking a commercial account

1. Who approves work orders and invoices, and how long does approval usually take?
2. What are the payment terms in writing, and what happens when an invoice is disputed?
3. What insurance limits, additional insured wording and safety documentation are required?
4. Are there after-hours access rules, badging or escort requirements on site?
5. How is emergency work requested at night and on weekends, and what response time is expected?
6. What is the termination notice period, and can either side end the agreement without cause?

If the answers would force you to change how your residential side runs, price the account for that disruption or decline it. A clear no is better than a contract that quietly costs more than it pays.

Choosing your mix

1. 01

   Measure your current mix

   Split the last twelve months of revenue, gross margin and days to payment by residential, rental and property management, commercial service and construction work.

2. 02

   Compare margin per labor hour

   Divide gross margin by technician hours for each segment, including drive and paperwork time. This often changes the picture more than revenue does.

3. 03

   Check your cash capacity

   Estimate how much working capital you would need to carry more commercial receivables.

4. 04

   Set a target mix and limits

   Choose a target share for each segment and a cap for any single account.

5. 05

   Shift gradually

   Add commercial service agreements before project work, and grow them alongside residential, not instead of it.

Example: a company finds residential service earns a gross margin of 120 per labor hour and is paid on the day, while a large commercial maintenance contract earns 85 per hour and pays in 45 days. The commercial contract still has value, because it fills slow weeks and is predictable, but the company decides to cap it rather than chase more bid work at the same margin.

Example: an HVAC company rebalances

Example (fictional): Northgate Mechanical had drifted to half its revenue from two builders' new-construction installs. When one builder slowed starts, install crews sat idle for six weeks. The owner moved two installers into residential replacement sales, built a maintenance agreement program for past customers and pursued service agreements with three local property managers.

Two years later, the builder share was below a quarter of revenue, residential service and replacement carried the margins, and property management work filled the shoulder seasons. For related moves, see government and municipal work, growing from 1 to 5 trucks and business valuation.
