Why Most Garage Door Owners Guess Wrong on Headcount (And How I Fixed It)

I've spent 25 years watching garage door company owners do the same thing: they feel busy, panic, hire three reps in a week, then wonder why six months later they're carrying dead weight while their spring leads rot. That's not a hiring problem—it's a math problem dressed up in work boots.

Here's the truth: you do not guess at headcount. You back into it from the gap between the revenue your installed jobs produce now and the revenue you want next year. The formula is simple once you stop treating it like a gut call: reps to hire = (net-new revenue you need / productive capacity per ramped rep) + backfills for attrition, adjusted for ramp time.

Let me walk you through how this actually works, because I've seen too many owners hire three estimators and end up with one good one and two people burning leads.

The Only Math That Matters

You start with what you know. Say you're at $4M in sold revenue and you want $6M. Your existing customers throw off $700K on their own through repeat service, replacements, and referrals—that's your base. So your base gets you to $4.7M, leaving $1.3M of net-new to sell.

Now, a fully ramped in-home rep closes $650K a year in installed garage doors and openers at a realistic close rate. That's 2 rep-years of capacity. But here's where novices trip: you add ramp time—an estimator hired today isn't productive until they learn your product lines, pricing, and close process.

And you add attrition—lose a third of a 6-rep team and you backfill 2 just to stand still.

Net it out? You're hiring roughly 3 to 4 reps, started early enough to ramp before spring demand hits.

I built a free Recruiting Calculator that runs this whole model—current and goal sold revenue, current and goal repeat-and-referral rate, ramp time, training length, attrition, and current headcount in; reps-to-hire and start dates out. No login, no spreadsheet, just your numbers and a defensible plan.

The Top 10 Tools to Figure Out How Many Sales Reps to Hire

Sales-capacity planning for a garage door company is a math problem dressed up as a hiring problem. Your reps are in-home salespeople and estimators—they run the appointment, measure the opening, walk the homeowner through door styles and opener options, and close on the spot or shortly after.

The tools below range from a free purpose-built calculator to field-service platforms and CRMs; what separates them is how directly they turn your revenue gap, ramp, and attrition into a headcount number. The model is always the same—revenue gap divided by productive capacity per rep, plus backfills, adjusted for ramp.

1. PULSE Recruiting Calculator 🏆 BEST OVERALL

🛠️ Use it free now -> Recruiting Calculator - no login, no spreadsheet, headcount plan with start dates in seconds.

PULSE's free Recruiting Calculator runs the entire capacity model in your browser. You type in the inputs every garage door owner already knows from their own numbers, and it returns how many in-home reps to hire and when they must start. Here is exactly what it asks and why each input matters:

Current sold revenue and goal sold revenue. The gap between the two is your starting point—how much total installed revenue you are trying to add this year across doors, openers, springs, and service upsells. The calculator uses it to size the whole plan.

Current and goal repeat-and-referral rate. This is your retention input for home services. A garage door is a long-life purchase, so growth does not come from re-selling the same homeowner every year—it comes from service calls, opener upgrades, second-door and rental-property jobs, and especially referrals from satisfied installs.

The calculator uses your repeat-and-referral rate to figure how much of next year's number your existing customer base produces on its own. Raise that rate—tighter follow-up, a service-plan offer, a referral program—and your reps have less net-new to chase. Retention and hiring are the same equation.

Productive capacity per rep. What a fully ramped in-home rep realistically closes in a year at your normal close rate—not the best month annualized. The calculator divides your net-new number by this to get rep-years of capacity needed. For a garage door estimator this is sold-and-installed revenue per rep, the number that actually shows up on the schedule.

Ramp-up time and training length. A rep hired today is not productive for the first stretch while they learn your door brands, opener SKUs, pricing tiers, financing options, and in-home close process. The calculator discounts a new hire's first-year contribution by the ramp, which is why you always hire more bodies than a naive "gap divided by per-rep revenue" would suggest—and why start dates matter as much as count, especially heading into your spring and storm-season peaks.

Current headcount and attrition. Apply your turnover rate to your current team and the calculator adds the backfills you need just to hold serve. In-home sales turns over fast; lose two of six estimators and two of your hires are replacing people, not adding capacity.

Put those in and it outputs a clean reps-to-hire number with start dates, so you can hand it to your recruiter or build your spring hiring plan around it. Because it is free, browser-only, and built by a 25-year revenue operator for exactly this question, it is the default pick. Best for: garage door owners and sales managers who want a defensible headcount plan in minutes without building a model from scratch.

2. ServiceTitan

ServiceTitan is the heavyweight field-service platform for home-services companies, and many larger garage door operations run on it. Pricing is custom by quote and lands at the higher end of the market, typically four figures a month once you add seats and features. Its value for this question is the data: it tracks sold revenue per rep, close rates per estimator, job revenue, and membership renewals, so you get real productive-capacity and repeat-rate inputs instead of guesses.

It will not hand you a hire number out of the box—you build the plan on top of its actuals—but few tools know your per-rep economics better. Best for established garage door companies that already live in ServiceTitan.

3. Housecall Pro

Housecall Pro is a popular, affordable field-service app for home-services trades, with plans commonly from around $59 to $149-plus per month plus per-user fees. For a small-to-mid garage door company it tracks jobs, revenue, and customer history, giving you the per-rep sold-revenue and repeat-customer numbers the capacity model needs.

It is lighter and cheaper than ServiceTitan, which suits owner-operators and growing crews. Best for smaller shops that want clean revenue-per-tech data without enterprise cost.

4. Jobber

Jobber is a field-service management tool built for service businesses, with plans from about $39 per month up to a few hundred for larger teams. It handles quoting, scheduling, invoicing, and client history, so you can pull sold revenue per rep and repeat-job rates to feed the capacity calculation.

It is straightforward and quick to set up, a good fit for garage door companies still on spreadsheets. Best for crews that want simple, affordable job and revenue tracking.

5. Salesforce

Salesforce is the CRM system of record many larger home-services companies adopt as they scale, with editions from about $25 per user per month (Starter) to $165-plus (Enterprise) before add-ons. With its reporting you can model sold revenue, close rates, and pipeline by estimator, giving you the actuals the capacity math needs.

It will not produce a hire number itself—you build that on top of the data—but it keeps the plan living next to the pipeline it depends on. Best for multi-location garage door companies that already manage their business in Salesforce.

The Punchline

You don't need to guess how many reps to hire. You need to run the math once, trust it, and start recruiting on the right timeline. The numbers don't lie—your gut does.
