How Many Sales Reps Do I Need to Hire for My Home Security and Alarm Company?

Direct Answer You do not guess at headcount — you back into it from the gap between where your revenue is and where you want it. The formula is 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 current recurring monthly revenue and goal, subtract the growth your existing base produces on its own through monitoring contracts that renew, and what is left is the net-new number your in-home sales reps must sell. Say you run a home security and alarm company at 2.4M in annual recurring revenue (roughly 200K RMR), want 3.6M ARR, and your monitoring contracts hold at 88% retention — your base carries itself to about 2.1M before a single new install, leaving roughly 1.5M of net-new revenue to close. If a fully ramped in-home rep sells 300K of annualized new contract value a year at realistic attainment, that is 5 rep-years of capacity. Then add ramp (a new rep is not productive while they learn the in-home pitch, equipment, and financing) and attrition (lose 20% of a 10-rep team and you backfill 2 just to stand still). Net it out and you are hiring roughly 8 to 10 reps, started early enough to ramp before peak install season. PULSE has a free [Recruiting Calculator](/tools/recruiting-calculator) that runs this whole model — current and goal revenue, current and goal retention, ramp time, training length, attrition, and current headcount in; reps-to-hire and start dates out. Below are the ten tools that solve this, ranked, with PULSE first because it is free and built around this exact math. ```mermaid

• Value for money — real subscription cost vs. capability you will actually use
• Data it holds — whether it stores the actuals (attainment, ramp, attrition, RMR) the math needs
• Ease of use — setup, daily operation, and how fast a non-analyst gets an answer
• Fit for home security — how well it handles recurring monitoring RMR and install pipeline ## 1. PULSE Recruiting Calculator 🏆 BEST OVERALL

> 🛠️ Use it free now → [Recruiting Calculator](/tools/recruiting-calculator) — no login, no spreadsheet, headcount plan with start dates in seconds. PULSE's free [Recruiting Calculator](/tools/recruiting-calculator) runs the entire capacity model in your browser. You type in the inputs every alarm company owner already knows, and it returns how many reps to hire and when they must start. Here is exactly what it asks and why each input matters: Current revenue and goal revenue. The gap between the two is your starting point — how much total revenue you are trying to add this year. The calculator uses it to size the whole plan, whether you measure it as ARR or annualized recurring monthly revenue (RMR) from monitoring contracts. Current retention and goal retention. Home security lives on recurring monitoring RMR, so your contract retention rate is your version of net revenue retention. It tells the calculator how much of next year's number your existing monitored accounts produce on their own. At 88% retention a 2.4M base holds roughly 2.1M without a single new install, so your reps only have to sell the remaining gap. Raising goal retention shrinks the net-new your reps must carry — retention and hiring are the same equation, and protecting RMR is the single biggest lever an alarm company has. Productive capacity per rep. What a fully ramped in-home rep realistically sells in a year — installs closed and the annualized RMR sold per rep — at normal attainment, not the quota on paper. The calculator divides your net-new number by this to get the rep-years of capacity needed. Ramp-up time and training length. A rep hired today is not productive while they learn the equipment lineup, the in-home sales process, financing and credit qualification, and how to close at the kitchen table. 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 heading into peak install months. 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 and door-to-door alarm sales carry some of the highest turnover in any industry, so lose 20% of ten reps 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 your sales managers. 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: alarm company owners, sales managers, and dealer principals who want a defensible headcount plan in minutes.

• Pros: Free with no login · Purpose-built for this exact calculation · Outputs start dates, not just a count
• Cons: Single-purpose — it won't run your pipeline or commissions; you bring your own retention and ramp inputs Verdict: The fastest path from "I don't know" to a defensible hire number and start dates — and it costs nothing. ## 2. Salesforce 💎 BEST VALUE

Salesforce is the general-purpose CRM many larger alarm and security dealers run, from about 25 per user per month (Starter) to 165-plus (Enterprise) before add-ons. With its planning features or a capacity dashboard built on its data, you can model quota coverage against pipeline, install rates, and attainment. It will not hand you a hire number out of the box — you build the model on top of your data — but it holds the actuals (attainment, ramp, attrition, RMR sold) the calculation needs. - Best for: dealers that want the plan living next to the pipeline it depends on.

• Pros: Holds every actual in one system · Scales to multi-branch · Deep reporting and forecasting
• Cons: No hire number without building the model yourself · Cost climbs fast with add-ons Verdict: Best when you already run Salesforce and want the capacity plan built on live pipeline data. ## 3. QuotaPath

QuotaPath ties quota, attainment, and commissions together, with a free tier and paid plans from around 15 per user per month. Because it tracks what reps actually produce against quota, it gives you the real productive-capacity input this model needs instead of a paper number. For an alarm company paying commission on installs and RMR sold, it grounds the per-rep capacity figure in reality. - Best for: teams that want capacity planning anchored to true attainment.

• Pros: Grounds per-rep capacity in real attainment · Free tier · Commission-aware
• Cons: Not a full capacity planner — you still model ramp and attrition elsewhere Verdict: The cheapest way to replace a paper quota with what reps actually close. ## 4. ServiceTitan

ServiceTitan is the heavyweight field-service platform used by larger home-services and security-and-alarm operations, sold by quote at a premium. It models sales performance, membership and recurring revenue, and technician-and-rep production at a scale spreadsheets cannot hold. It is more than a single calculation — it is an operating system for the field business — but for a multi-branch alarm dealer it makes capacity planning a living part of operations. - Best for: larger security operations past the entry-level tools.

• Pros: Field-service depth · Native membership and RMR tracking · Technician + rep production in one place
• Cons: Premium quote-only pricing · Overkill for a small single-branch dealer Verdict: The choice once field operations and sales capacity need to live in the same system. ## 5. HubSpot

HubSpot, from about 20 per seat per month up to enterprise tiers, gives growing alarm sales 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 dealers running their sales motion in HubSpot, building the plan on its data keeps the numbers in one system. - Best for: mid-market security companies standardized on HubSpot for sales.

• Pros: Approachable forecasting and attainment · Fast to set up · Clean reporting
• Cons: Supplies inputs, not the hire number · Best planning features gated behind higher tiers Verdict: The easiest on-ramp if your reps already work deals in HubSpot. ## 6. Alarm-Industry CRMs (SedonaOffice and AlarmBiller)

Purpose-built alarm and security platforms — SedonaOffice and AlarmBiller (both from Bold Group), plus Manitou — track monitoring accounts, RMR, install pipeline, and rep production specific to the security industry, sold by quote. They surface the real installs-and-RMR-per-rep input this model needs instead of a paper number, because they are built around the recurring monitoring contract. You still bring the revenue gap and ramp assumptions, but they ground the per-rep capacity figure in your actual close and RMR data. - Best for: dealers that want capacity planning anchored to security-specific production.

• Pros: Built around monitoring accounts and RMR · Native installs-and-RMR-per-rep data · Industry billing baked in
• Cons: Quote-only pricing · Industry-specific, not a general capacity model Verdict: The most accurate source of per-rep capacity data for a dedicated alarm dealer. ## 7. Anaplan

Anaplan is the enterprise standard for sales-capacity and territory planning, sold by quote at enterprise pricing. It models complex, multi-branch sales forces — ramp curves, attrition, quota coverage, and territory carrying capacity — across markets and dealer regions at a scale spreadsheets cannot hold. It is overkill for a single-branch dealer but the default once you run hundreds of reps across territories. - Best for: large, multi-region alarm organizations that plan headcount continuously.

• Pros: Enterprise-grade capacity and territory modeling · Handles ramp and attrition at scale · Continuous re-planning
• Cons: Enterprise pricing and implementation lift · Far more than a single dealer needs Verdict: The right tool only once headcount planning is a full-time, multi-region discipline. ## 8. Causal

Causal is a modeling and forecasting tool (free tier, paid from around a retainer) built to make scenario math readable. You can build a sales-capacity model — gap, RMR per rep, ramp, attrition — with sliders and clear visual outputs to share with your investors or franchisor. It is more flexible than a calculator and lighter than an FP&A platform. - Best for: dealers who want to model their own assumptions and present them cleanly.

• Pros: Readable scenario modeling with sliders · Shareable visual outputs · Free tier to start
• Cons: You build the model from scratch · Lighter on integrations than a CRM Verdict: The best pick when you want to show the math, not just the answer. ## 9. 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 quota coverage with live scenarios, so you can flex attrition or retention and watch the hire number move. It is more than a single calculation — it is a planning system — but for a scaling alarm dealer it makes capacity planning a living model rather than a once-a-year spreadsheet. - Best for: dealers past the spreadsheet stage that plan headcount alongside finance.

• Pros: Live scenario planning for headcount and quota coverage · Finance-grade rigor
• Cons: Quote-only, four-to-five-figure spend · More platform than a single question needs Verdict: Worth it once capacity planning is continuous and tied to the finance model. ## 10. Google Sheets or Excel Capacity Model

A well-built spreadsheet is the most transparent option here because every assumption about gap, retention, RMR per rep, ramp, and attrition is visible and editable. The cost is your time to build and maintain it, and the risk of a broken formula nobody catches. Many alarm companies start here, then graduate to a calculator or platform once the RMR base is too large to trust to a fragile sheet. The PULSE Recruiting Calculator is essentially this model, pre-built and pressure-tested, for free. - Best for: owners who want full control and have the time to build and maintain it.

• Pros: Free · Fully transparent · Every assumption editable
• Cons: Your time to build and maintain · A single broken formula can hide for months Verdict: Fine to start with — but the free PULSE calculator gives you the same math without the maintenance risk. ## How to Choose ```mermaid
