A maintenance membership program grows on one number most shops never measure: how often the plan gets offered. Renewal rate and pricing get the attention, and both matter. But a technician who mentions the plan on half their repair calls caps the program at half its potential before a single customer decides anything.
This hub is about the marketing side of memberships: who to offer them to, when, through which channel, and how to measure it from your jobs. Designing and pricing the plan is covered in our HVAC maintenance plans guide, and keeping members is covered in memberships that actually renew.
The offer-rate equation
Membership conversion rate, the share of eligible non-members who join after a visit, hides two very different things.1 Split it and the fix becomes obvious.
Where new members come from
Example (hypothetical). Say a shop completes 400 eligible non-member visits a month. Techs offer the plan on 35% of them, and 30% of those offered say yes: 400 × 35% × 30% = 42 new members. Training customers to say yes more often is slow work. Getting techs to offer on 70% of visits, at the same acceptance rate, doubles sales to 84 a month without changing the plan or the price.
The point isn't that acceptance doesn't matter. It's that offer rate is usually the bigger gap, and it's measurable per technician and per job type once the offer is recorded on the job.
Where memberships get sold
Each selling moment has a different customer state and a different owner.
| Moment | Who sells | Why it works | Record on the job |
|---|---|---|---|
| After a repair | Technician | The customer just paid for a problem a visit might have caught | Offered yes or no, accepted yes or no |
| At an install | Comfort advisor or installer | New equipment benefits from regular care; the plan can start with the install | Plan sold with the install |
| During a non-member tune-up | Technician | The customer already pays for maintenance one visit at a time | Offered, accepted |
| At booking | CSR | A non-member calling for service can hear the member price for this call | Mentioned at booking |
| From the office list | CSR or mail | Past repair customers who weren't offered, or said not now | Campaign on the resulting membership |
The office list matters more than it looks. Past non-member customers with recent repairs are warm, and they're already in your records. Email them only if they've given marketing consent, with a working opt-out honored within 10 business days, as the FTC's CAN-SPAM guide requires.2
Selling online and on autopay
If customers can sign up on your website and pay automatically, federal law sets a floor. The Restore Online Shoppers' Confidence Act requires a seller charging for an online negative-option plan to disclose all material terms before taking billing information, get the customer's express informed consent before charging, and provide a simple way to stop recurring charges.3 Several states add their own automatic-renewal rules; the maintenance plans guide linked above covers the common ones.
Visits due are a marketing list
A member's due visit is the one marketing touch you don't have to buy. ENERGY STAR advises checking the cooling system in spring and the heating system in fall.4 Book those visits into the shoulder weeks before demand peaks, and each one does three jobs: it keeps the promise that drives renewal, it finds repairs, and it puts a technician in the home with equipment you can see aging year by year.
The failure mode is a due list nobody works. If visits slide into peak season, they compete with paid emergency calls and often get pushed again.

How to measure it from your jobs
Four numbers cover the marketing side of a membership program. All of them come from job and membership records, not surveys.
Metric
Offer rate
How often an eligible non-member is offered the plan. The number most programs never see.
Eligible non-member visits with the plan offered ÷ eligible non-member visits
Where the numbers come from: An offered yes/no on the job, by technician and job type.
Metric
Acceptance rate
How often an offer becomes a sale.
Memberships sold on offered visits ÷ visits where the plan was offered
Where the numbers come from: Membership sale linked to the job it was sold on.
Metric
Visits due booked on time
The share of member visits booked before their due month ends. It predicts renewal better than any survey.
Member visits booked by the end of the due month ÷ member visits due that month
Where the numbers come from: Membership visits due and the jobs booked against them.
Metric
Membership share of revenue
How much of invoiced revenue comes from members, including the repairs they call you for.
Invoiced revenue from active members ÷ total invoiced revenue
Where the numbers come from: Invoices joined to membership status on the invoice date.
Where TradesWork fits
TradesWork runs memberships with visits due and renewals, builds lists from your records (memberships expiring, maintenance due, lapsed customers), and checks marketing consent before anyone lands on a list. It knows open technician hours for the next 30 days, so you can see where due visits fit. It doesn't send marketing email or text broadcasts yet. For the details, see the memberships feature.
