SERVICE BUSINESS

RECURRING REVENUE VS BACKLOG.

QUICK ANSWER

Backlog is signed work not yet performed. It's finite, it burns down as crews build it, and it's worth the margin still sitting inside it. A service business signs agreements instead of scopes, so nothing burns down: the contract book either renews or churns. That changes what you measure every month, what a bank underwrites, and what a buyer will pay.

The trouble starts when a service owner opens a backlog report and sees close to zero. Nothing is wrong with the business and nothing is wrong with the report. Backlog counts contracted scope waiting to be built, and a service agreement is a standing right to order work. An owner who reads that empty report as a warning will go chase volume the business never needed.

THE DEFINITION

WHAT IT MEANS.

A contract book is the set of recurring service agreements a business holds: the customers who have committed to ordering work, rather than the work itself. It's the service equivalent of backlog, and it behaves nothing like it.

We publish no service business margin benchmarks, and we won't price your book against one. Labor rates, drive time, competitive density, and what a market will pay for a recurring agreement vary more between two metros than they do between two trades, so a national average is wrong almost everywhere somebody reads it. The 48 trade benchmark set we do publish is project based construction data and it doesn't transfer to a service book. Your targets get built from your own agreements, your own renewal history, and your own cost per stop, which is less comfortable than an average and considerably more useful.

This confusion is common because most service businesses are run by people who came out of project work, or because the same company does both. The instincts carry over even when the instruments don't. An owner who spent fifteen years reading a schedule of values will keep looking for the document that tells him how much work is committed, and in a service business that document has to be built rather than borrowed.

WHAT WE SEE IN A SERVICE BOOK

WHY THE BACKLOG REPORT READS EMPTY.

01

The backlog report has nothing to report

A service business signs agreements, not scopes of work, so there's no contracted quantity sitting there waiting to be performed. Open a backlog schedule and it reads close to zero even when the business has more predictable revenue than any project contractor on the street. The report isn't broken. It's answering a question this business doesn't ask.

02

Churn doesn't announce itself

A project contractor watches backlog fall every month and knows the day he has to sell again. A contract book gives no such signal, because a customer who is about to stop renewing looks like a paying customer right up until the renewal is skipped. Without a renewal rate calculated monthly, the first sign of trouble is a revenue decline that began three quarters earlier.

03

A backlog mindset sends the effort to the wrong place

Backlog thinking says the answer to a soft month is more sold work, so the owner puts every dollar of attention into new sales. In a service book the cheapest revenue in the building is the agreement already signed, and one lost renewal costs the entire future stream rather than one job's margin. Owners running on backlog instincts routinely spend more winning a replacement customer than they would have spent keeping the one who left.

04

The bank and the buyer are reading a different asset

A lender treats backlog as a finite pipeline and discounts it to the margin it still carries, because once it's built it's gone. A contract book gets underwritten as a renewing revenue stream, so the questions become renewal rate, contract length, customer concentration, and how much of the book sits under a written agreement rather than a long standing habit. An owner who presents a service business as though it has backlog gives the bank the weaker of the two true stories about the same company.

THE ARITHMETIC

WHAT IT LOOKS LIKE IN DOLLARS.

Revenue per agreement, worked as an example

Take a book of 120 agreements producing $1,440,000 of contracted revenue in a year. That's $12,000 per agreement, which is the figure that tells you what a single renewal is worth. Lose 12 of them and $144,000 of next year's revenue is gone before anybody makes a sale. Those are example figures we built to show the arithmetic, and they carry no industry authority.

What ten points of renewal does, as arithmetic

Start with $2,000,000 of recurring revenue and sell nothing new. At an 85 percent renewal rate the book produces $1,700,000, then $1,445,000, then roughly $1,228,000 across three years. At 95 percent it produces $1,900,000, then $1,805,000, then about $1,715,000. Ten points of renewal is close to half a million dollars of difference by year three on the same book, and the rates here are illustrations chosen to demonstrate the mechanism rather than targets anybody should price against.

Why the two assets aren't worth the same thing

Assume $1,000,000 of backlog carrying $150,000 of margin. It contributes $150,000 once and then it's finished. Assume instead $1,000,000 of annual recurring revenue renewing at 90 percent: it produces $900,000 next year with no sale made, and it keeps producing after that. Same headline dollar figure, completely different asset. The margin and renewal rate in that comparison are ours for the sake of the math.

HOW SPM FIXES IT

WHAT REPLACES BACKLOG.

A contract book schedule, in place of backlog

Every agreement is listed with its start date, its term, its renewal date, its billing frequency, and its annual contracted value. That schedule is the service equivalent of a WIP report and it's the document the monthly meeting runs off. It tells you what's contracted, what comes up for renewal inside the next 90 days, and how much of your revenue sits under agreement rather than being ordered at will.

Renewal rate and revenue per agreement, reported monthly

Renewal rate is the share of agreements up for renewal that renewed, calculated every month instead of once a year when it's too late to do anything about it. Revenue per agreement tells you what one renewal is worth and whether the book is growing by customer count or by price. Together they replace the two things backlog gave a project contractor: how much future revenue is committed, and how fast it's disappearing.

The 13 week forecast, built off billing cycles

A service business bills on a cycle and not on progress, which makes the 13 week cash forecast easier to build and no less necessary. Recurring invoices go in on their billing dates, work order revenue goes in on collection history, and the funding decision gets made before the week starts. Books close by the tenth so the forecast runs off finished numbers rather than estimates.

A book you can put in front of a bank or a buyer

The schedule that runs your month is the same schedule a lender or an acquirer wants to see, with renewal history attached to it. Written agreements, contract terms, renewal rate over time, and customer concentration are what turn recurring revenue into an asset somebody will underwrite or pay a multiple for. Verbal arrangements with loyal customers count for nothing in that conversation, however reliable they have been for you.

COMMON QUESTIONS

FREQUENTLY ASKED.

No, and building one is wasted effort. WIP exists to true up revenue against progress on a fixed price scope, and a service agreement has no scope to measure progress against. What a service business needs instead is a contract book schedule and an unbilled work order report, because the money most often lost here is work performed and never invoiced rather than revenue recognized at the wrong percentage.
Backlog is worth the margin left inside it, once. A contract book is priced off the recurring revenue it produces and the rate at which that revenue renews, so the multiple a buyer applies follows renewal rate, contract length, and customer concentration rather than the trade. That's why two service businesses with identical revenue can be worth very different amounts. The one with written multi year agreements and a documented renewal history is buying itself a better number.
We won't read you a figure off a chart, because a defensible target for a recurring agreement moves too much by region and service line for an average to mean anything where you operate. What we do is calculate your own renewal rate from your own history, then set the target above it and report against it every month. Beating your own number by ten points is worth more to you than matching somebody else's national average.
Separately, because blending the two hides both. Project work goes on a WIP schedule with backlog and retainage against it; service agreements go on the contract book schedule with renewal dates against them. Overhead gets allocated between the two on a basis you can defend, and the monthly meeting reviews each on its own terms before anybody looks at the company total.
Three tiers, and which one you are in depends on how much of the work you want off your desk. Core is where you stop guessing: job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a monthly meeting that ends in decisions, while your bookkeeper keeps doing the books. Executive is where you stop touching the books, because we run the bookkeeping and the controllership as well. Strategic is where every job shows its margin while it is still running, because the job costing and WIP platform is set up and managed for you. No payroll. No scope gaps.
