The short answer
Recurring work on a written schedule smooths your seasons and can make the business worth more, because a buyer or a banker can count on it. Customer mix matters too: if one customer pays a big share of your sales, losing them hurts now and lowers your value later. M&A advisers say to keep any one customer under about 10%–15% of sales.
What recurring work looks like in pavement
Recurring work is work under a written agreement that repeats: crack repair and restriping every year, sealcoating on a cycle, sweeping or pressure washing, snow and ice every winter. The best customers for it own or manage lots they can't ignore: property managers, homeowners associations, churches, schools, retail centers and offices.
Set the schedule with the customer from the lot's condition and their budget. Some years the honest answer is "not yet," and saying so is part of why agreements renew.
M&A advisers say recurring maintenance work can be valued at a higher multiple than one-time work, because the next year's revenue is already partly spoken for. It helps now too: signed spring work in January makes it easier to plan crews and buy materials.
Plenty of good shops run mostly one-time residential work and do well. Recurring work is a choice with trade-offs: smaller tickets per visit, more account management, and promises you have to keep on schedule.
Customer concentration: how much is too much
A customer's share is their sales divided by your total sales. Example (made-up numbers). Carol (example) owns a 22-person paving maintenance company with $3,000,000 in sales last year.
| Customer | Sales | Share |
|---|---|---|
| Property management firm | $600,000 | 20% |
| Church and school group | $240,000 | 8% |
| Retail center owner | $150,000 | 5% |
| HOA management company | $120,000 | 4% |
| Hospital campus | $90,000 | 3% |
One customer is 20% of Carol's sales. If that firm changes managers and switches contractors, she loses a fifth of her revenue in one phone call. A buyer sees the same risk and may lower the price, tie part of it to keeping that customer, or walk away.
The fix is rarely to fire the big customer. Grow other accounts so the share falls, put the big relationship under a written agreement, and make sure more than one person on each side knows the account.
Contracts and records a buyer can count on
A recurring agreement should spell out the scope, the schedule, how pricing is set each year, the renewal date and how either side can end it. Buyers also read whether the agreement can transfer to a new owner. Many contracts can't be assigned without the customer's consent, so have an attorney review your standard agreement for an assignment clause before you roll it out.
Keep each customer's history in a system the business owns: site maps, photos, past work and dates, products used, contacts and notes. If the history lives in your head or your truck, it leaves with you.
Track renewals on one list with every agreement's renewal date, and work it a month or two ahead. Renewal rate = agreements renewed ÷ agreements up for renewal. Example (made-up numbers): 40 agreements came up for renewal and 34 renewed, an 85% renewal rate.
Your Move
Do this week
- Pull last year's sales by customer from your books.
- List your top ten customers and each one's share of total sales.
- Mark any customer above about 10%–15% and write one step to grow other accounts.
- Draft one maintenance agreement offer for a property you already serve: scope, a schedule set from the lot's condition, renewal terms, and an assignment clause for your attorney to review.
Log it: Top-ten customer list done.
Common questions
What counts as recurring revenue for a pavement contractor?
Work under a written agreement that repeats on a schedule, such as yearly crack repair and striping, sealcoating on a cycle, sweeping, pressure washing, or a snow and ice contract. Repeat customers without a contract help too, but buyers give more weight to signed agreements.
Is one big customer always bad?
No. A big customer can carry a young business for years. The risk is depending on them, so grow other accounts until losing that one wouldn't threaten payroll.
Should I lock customers into long contracts?
Write terms that fit the work the lot needs and give both sides a fair way out. Honest scope and fair terms are what get agreements renewed.
Watch out for
- Selling work a lot doesn't need to keep a schedule full.
- Handshake deals with your largest customers. A buyer can't count what isn't written.
- One person at your company holding every big relationship.
- Agreements that can't be assigned. A buyer may need each customer's consent before closing.
