How Many Sales Reps Do I Need to Hire for My Elevator Maintenance Company?

I’ve been in the revenue game for 25 years, and if there’s one question that keeps elevator maintenance owners up at night, it’s this: “How many sales reps do I need?” The answer isn’t a gut feeling or a round number you scribble on a napkin. It’s math—cold, hard, elevator-shaft-reliable math.

And I’ve learned the hard way that guessing wrong costs you either lost contracts or bloated payroll.

Here’s my take: you don’t guess at headcount. You back into it from the gap between the recurring service revenue you have and the recurring service revenue you want. The formula is simple: reps to hire = (net-new revenue you need / productive capacity per ramped rep) + backfills for attrition, adjusted for ramp time. Work it in order: start with your current maintenance-contract revenue and your goal, subtract the growth your existing portfolio produces on its own at your contract renewal rate, and what’s left is the net-new number your reps must sign.

Let me walk through a real-world example. Say you run $6M in annual service-contract revenue, want $9M, and renew 92% of contracts each year. Your renewing base carries to roughly $5.52M, leaving about $3.48M of net-new agreements to sell.

If a fully ramped rep books $580K of new annual recurring service revenue a year at realistic attainment, that’s about 6 rep-years of capacity. Then add ramp—a rep who just learned the difference between a full-maintenance and a parts-and-labor contract is not productive for months—and attrition (lose 20% of a 10-rep team and you must backfill 2 just to stand still).

Net it out and you’re hiring roughly 8 to 10 reps, started early enough to ramp before bid season.

PULSE has a free Recruiting Calculator that runs this whole model—current and goal contract revenue, current and goal renewal rate, ramp time, training length, attrition, and current headcount in; reps-to-hire and start dates out. It’s the tool I wish I’d had back when I was building teams from scratch.

Below are the ten tools that solve this, ranked, with PULSE first because it’s free and built around this exact math.

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

Sales-capacity planning for an elevator maintenance company is a math problem dressed up as a hiring problem. The tools below range from a free purpose-built calculator to enterprise planning platforms; what separates them is how directly they turn your service-revenue gap, ramp, and attrition into a headcount number.

Whether you sell full-maintenance agreements to property managers, modernization projects to building owners, or both, the model is the same—net-new recurring revenue divided by productive capacity, 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 elevator service leader already knows, and it returns how many reps to hire and when they must start. Here’s exactly what it asks and why each input matters:

• Current contract revenue and goal contract revenue. The gap between the two is your starting point—how much total annual service revenue you’re trying to add. For an elevator maintenance company that means new full-maintenance and parts-and-labor agreements, not one-time repair tickets. The calculator uses the gap to size the whole plan.
• Current renewal rate and goal renewal rate. Your contract renewal rate is the elevator-industry version of net revenue retention—it tells the calculator how much of next year’s number your existing portfolio of buildings produces on its own. At 92% renewal a $6M base holds about $5.52M before a single new building is signed, so your reps only have to sell the remaining gap. Raising goal renewal shrinks the net-new your reps must carry—retention and hiring are the same equation, and one lost high-rise route can wipe out a rep’s whole quarter.
• Productive capacity per rep. What a fully ramped rep realistically books in new annual recurring service revenue at normal attainment—not the number on the comp plan. The calculator divides your net-new figure by this to get rep-years of capacity needed.
• Ramp-up time and training length. A rep hired today is not productive for the first few months while they learn callback rates, code-compliance talking points, and how to read a route, and while they build a pipeline of property managers. 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 quota” would suggest—and why start dates matter as much as count.
• Current headcount and attrition. Apply your turnover rate to your current team and the calculator adds the backfills you need just to hold serve. Lose 20% of ten reps and two of your hires are replacing people, not adding routes.

Put those in and it outputs a clean reps-to-hire number with start dates, so you can hand it to your recruiter or your ownership group. Because it’s free, browser-only, and built by a 22-year revenue operator for exactly this question, it’s the default pick. Best for: owners, GMs, and sales leaders at elevator maintenance companies who want a defensible headcount plan in minutes without building a model from scratch.

2. Salesforce (with capacity planning)

Salesforce is the system of record many larger elevator service companies run, and with its planning features or a capacity dashboard built on its data, you can model contract coverage against pipeline and attainment. Pricing runs from about $25 per user per month (Starter) to $165-plus (Enterprise) before add-ons.

It won’t hand you a hire number out of the box—you build the model on top of your data—but it holds the actuals (book of business, win rate, attrition) the calculation needs. Best for: teams that want the plan living next to the pipeline of buildings it depends on.

3. ServiceTitan

ServiceTitan is field-service management software widely used by mechanical and elevator service contractors, sold by quote (commonly four figures a month for a real crew). Because it tracks your service agreements, contract values, and renewal activity, it gives you the real recurring-revenue and renewal inputs this model needs instead of guesses.

You still bring the growth goal and ramp assumptions, but it grounds the per-rep capacity figure and the renewal rate in actual contract data. Best for: service contractors who already run dispatch and agreements in one system.

4. HubSpot Sales Hub

HubSpot Sales Hub, from about $20 per seat per month up to enterprise tiers, gives growing elevator service teams forecasting and attainment data plus planning tools to size coverage against goals. Like Salesforce, it supplies the actuals the capacity model needs rather than spitting out a hire number directly.

For a regional elevator company standardizing its first real CRM, building the plan on HubSpot data keeps prospecting, deals, and reporting in one place. Best for: mid-market service teams without a heavy enterprise stack.

5. Pigment

Pigment is a modern business-planning platform built for RevOps and finance, sold by quote (commonly four to five figures a year). It models headcount, capacity, ramp, and contract coverage with live scenarios, so you can flex attrition, renewal rates, and rep productivity in real time without rebuilding a spreadsheet.

Best for: teams that need to run multiple what-if scenarios on their sales capacity and headcount plan.

Here’s the closing line I’ll leave you with: Hiring sales reps isn’t a guess—it’s a formula. Get the numbers wrong and you’ll either starve your growth or drown in payroll. If you want the quickest path to a defensible number, grab PULSE’s free Recruiting Calculator at CRO Syndicate.

It’s the same math I’ve used for decades, now in a browser. No excuses.
