The economics of commercial boiler service agreements

Step 1: what one building brings in each year

Start with the full annual revenue from an agreement building, not just the agreement fee.

A building under agreement typically generates three kinds of revenue for you:

1. The agreement fee itself: scheduled maintenance visits, inspections support and whatever else your tiers include.
2. Pull-through repairs and parts: work found during visits, or after-hours calls the building sends you first because you already know the plant.
3. Replacement and upgrade work: occasional, but large. A building that trusts you will usually invite you to quote when equipment reaches the end of its life.

For this guide, assume an illustrative mid-rise rental building:

Your numbers will differ. Pull your last two years of invoices for buildings under agreement and average them. If you don't separate agreement buildings from others in your books, that is the first thing to fix.

Step 2: what that revenue is worth after costs

Revenue is not profit. Apply your gross margin: the share left after technician labour, parts and direct costs, before overhead.

If your blended gross margin on commercial work is 40%, the building above produces $4,800 a year in gross profit.

Be honest here. Agreement visits may carry a different margin from emergency repairs or replacements. If you can, calculate each line separately. For this guide, we keep one blended figure.

Step 3: how long the building stays

This is where most owners are surprised. The expected life of an agreement depends on your renewal rate, and small changes make a large difference.

A simple estimate: expected years = 1 ÷ annual churn rate, where churn is the share of agreements you lose each year.

This formula is a simplification. Real buildings are sold, change managers or go to tender for reasons you can't control. But it is close enough for planning, and it shows the key point: moving from 80% to 90% renewal doubles the expected life of every agreement.

Step 4: lifetime value

Multiply annual gross profit by expected years.

At 85% renewal, the illustrative building is worth $4,800 × 6.7, or about $32,000 in gross profit over its life with you.

At 75% renewal, it is worth $4,800 × 4, or about $19,200.

That gap of nearly $13,000 per building comes entirely from renewals. If you hold 60 agreement buildings, the difference between those two renewal rates is worth roughly $770,000 in lifetime gross profit across the book. No new-business campaign is likely to match that return for the effort involved.

Step 5: what you can afford to spend to win a building

Once you know lifetime value, you can set an acquisition budget with confidence.

A conservative rule is to spend no more than a quarter to a third of lifetime gross profit to win a building. Using $32,000:

• One quarter: $8,000 per building won
• One third: about $10,700 per building won

That budget covers everything: marketing fees, ad spend, the time your owner or commercial lead spends on walkthroughs and quotes, and any trial pricing. Most owners have never allowed themselves to spend that much, which is why commercial growth stalls.

Two cautions:

1. Cash flow. You spend the money up front and earn it back over years. Make sure the business can carry that gap.
2. Uncertainty. If your margin or renewal figures are rough guesses, use the lower budget until you have real data.

Step 6: test the plan against your marketing costs

Now compare the acquisition budget with an actual plan. Suppose your total annual marketing cost for commercial work, including fees and ad spend, is $72,000.

• At $8,000 per building, you need 9 new buildings a year to stay within budget.
• If your realistic target is 4 buildings, either the plan is too large, or your lifetime value is higher than you think and you should check it.

This is the conversation we have with every commercial client before recommending a plan. It is also covered on our pricing page.

Where the value hides: three levers

Lifetime value has three inputs, and each can be improved with marketing.

Lever 1: renewal rate

The most valuable lever. Practical steps:

• Start renewal conversations at least 90 days before the end date.
• Send every building a short annual service summary before renewal.
• Call the manager after any after-hours emergency to explain what happened.
• Track renewal rate monthly, by building type.

Our service agreement marketing service sets up exactly this.

Lever 2: annual revenue per building

Better tier design raises revenue without discounting:

• Offer two or three tiers, with the middle one designed as the natural choice.
• Make documentation, priority response and seasonal start-up visible parts of the value.
• Present replacement planning as a service, not a sales pitch: a written note on equipment approaching end of life lets a board budget ahead.

Lever 3: margin

Marketing affects margin indirectly. Agreement buildings tend to be cheaper to serve than one-off emergencies, because visits are scheduled and technicians know the plant. Shifting your mix from emergencies to agreements usually improves blended margin.

Common mistakes in agreement maths

• Counting only the agreement fee. It understates value, often by half or more.
• Ignoring churn. Treating every agreement as permanent overstates value; treating it as one year understates it badly.
• Discounting to win. A 20% discount to win a building cuts lifetime value by the same 20%, every year.
• Not segmenting. A care home and a ten-suite walk-up have very different values. Calculate them separately.
• No baseline. If you don't know today's renewal rate, you can't tell whether anything improved it.

A one-page worksheet

Fill these in from your own records:

1. Average annual agreement fee: $____
2. Average annual pull-through repairs and parts: $____
3. Average annual replacement work: $____
4. Total annual revenue per building (1+2+3): $____
5. Blended gross margin: ____%
6. Annual gross profit per building (4 × 5): $____
7. Renewal rate over the past two years: ____%
8. Expected years (1 ÷ (1 − 7)): ____
9. Lifetime gross profit (6 × 8): $____
10. Acquisition budget per building (9 × 0.25 to 0.33): $____

What to do with the result

If your lifetime value is high and your renewal rate is good, invest in winning new buildings through commercial search and a property manager pipeline. If renewal is weak, fix that first: every new building you win will leak away at the same rate.
