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

Direct Answer You do not guess at headcount — you back into it from the gap between the revenue you are booking and the revenue you want. 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 your current sold revenue and your goal, subtract the work your existing customer base produces on its own through service agreements and repeat-and-referral business, and what is left is the net-new revenue your sales reps and estimators must sell. Say you are booking a retainer, want 4M, and your maintenance agreements plus repeat customers reliably deliver a 40% repeat rate — your base carries roughly 1.2M of next year on its own, leaving about 1.8M of net-new to sell from new leads and bigger jobs. If a fully ramped sales estimator sells a retainer of jobs at realistic close rates, that is 3 rep-years of capacity. Then add ramp — a new estimator is not productive while they learn your pricing book, code, and how to run a callback — and attrition: lose one of three estimators and you backfill one just to stand still. Net it out and you are hiring roughly 4 to 5 reps, started early enough to ramp before peak season. PULSE has a free [Recruiting Calculator](/tools/recruiting-calculator) that runs this whole model — current and goal revenue, current and goal repeat/retention rate, 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 monthly cost versus the features a plumbing shop will actually use
• Integrations — how cleanly it connects to your accounting, dispatch, and CRM
• Support and reliability — onboarding, uptime, and owner satisfaction
• Ease of use — setup and daily operation for a non-technical team ## 1. PULSE Recruiting Calculator 🏆 BEST OVERALL

> 🛠️ Use it free now → [Recruiting Calculator](/tools/recruiting-calculator) — no login, no spreadsheet, a 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 plumbing-company owner already knows, and it returns how many sales reps and estimators to hire and when they must start. Here is exactly what it asks and why each input matters for a plumbing business: Current revenue and goal revenue. The gap between the two is your starting point — how much total sold revenue you are trying to add this year. The calculator uses it to size the whole plan, whether the growth is more service tickets, more replacements, or bigger install jobs. Current and goal repeat/retention rate. Your repeat-and-referral rate — fed by service agreements and happy customers — tells the calculator how much of next year's number your existing base produces on its own. At a 40% repeat rate, a healthy book of maintenance-agreement customers carries a big chunk of next year before a single cold lead. Raising that rate — more agreements sold, faster callbacks, tighter follow-up — shrinks the net-new your estimators must carry. Retention and hiring are the same equation. Productive capacity per rep. What a fully ramped estimator or sales-tech realistically sells in a year at a normal close rate — not the number on a poster. The calculator divides your net-new revenue by this to get the rep-years of capacity you need. Ramp-up time and training length. A new estimator hired today is not productive for the first few weeks to months while they learn your flat-rate pricing book, your good-better-best options, code, and how to turn a service call into a sold job. 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, especially before peak season. Current headcount and attrition. Apply your turnover rate to your current sales team and the calculator adds the backfills you need just to hold serve. Lose one of three estimators and a third of your hiring plan is 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 GM. 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: plumbing-company owners, sales managers, and operations leaders who want a defensible headcount plan in minutes without building a model from scratch.

• Pros: Free, no login or spreadsheet · Outputs start dates, not just a count · Built around this exact math
• Cons: Purpose-built for headcount planning — it is not a CRM or field-service system Verdict: The default starting point — it answers the exact question, for free. ## 2. ServiceTitan 💎 BEST VALUE

ServiceTitan is the leading field-service management platform for residential and commercial plumbing, sold by quote (commonly four figures a month for a growing shop). Its sales and reporting tools track sold revenue per technician, close rates, average ticket, and membership growth — the exact actuals the capacity model needs. It will not hand you a hire number out of the box, but no platform ties your sold-revenue and service-agreement data together more completely for a plumbing business. Best for: established plumbing companies that already run the whole operation on ServiceTitan.

• Pros: Deep plumbing-specific reporting · Ties sold revenue to memberships · Enterprise-grade
• Cons: Quote-based pricing runs high for small shops · Won't output a hire number Verdict: Best if your whole operation already lives in it — the actuals are all there. ## 3. Housecall Pro

Housecall Pro is a popular, affordable field-service platform (plans commonly from about a retainer up to higher tiers) built for small and mid-size home-services businesses. It tracks jobs, estimates, sold revenue, and recurring service plans, giving you the per-tech productivity and repeat-revenue inputs the model needs. It is lighter and cheaper than ServiceTitan, so it suits smaller plumbing shops that still want real numbers. Best for: growing plumbing companies that want strong reporting without enterprise pricing.

• Pros: Affordable entry tier · Tracks jobs, estimates, and recurring plans · Easy to set up
• Cons: Lighter reporting than ServiceTitan once you scale past a few crews Verdict: A strong middle option for small-to-mid shops that still want honest data. ## 4. Jobber

Jobber is the best low-cost option among the dedicated platforms because it delivers job tracking, quoting, sold-revenue reporting, and client follow-up at a low entry price — plans commonly from around a retainer. For a small plumbing company, that is enough to pull accurate per-estimator capacity and repeat-rate numbers without paying for features you will not use. It will not compute a hire number, but it gives you the honest inputs the calculator needs, cheaply. Best for: small plumbing teams that want field-service rigor on a tight budget.

• Pros: Low entry price · Clean quoting and sold-revenue tracking · Fast to adopt
• Cons: No built-in capacity or headcount modeling Verdict: The best value for pulling honest capacity inputs without overspending. ## 5. FieldEdge

FieldEdge is a field-service management platform built for plumbing, HVAC, and electrical contractors, sold by quote. It connects dispatch, service agreements, and invoicing with reporting on revenue per tech and membership renewals, so the recurring and repeat-revenue inputs your capacity model needs are in one place. Its QuickBooks integration makes the sold-revenue actuals clean. Best for: plumbing companies that want service-agreement tracking tied tightly to their books.

• Pros: Strong service-agreement tracking · Tight QuickBooks sync · Contractor-focused
• Cons: Quote-based pricing · Interface feels dated next to newer tools Verdict: A good fit when clean books and membership data matter most. ## 6. 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 each estimator actually sells against quota, it gives you the real productive-capacity input this model needs instead of a paper number. For a plumbing company paying estimators on a commission or spiff plan, it also keeps comp aligned to the sold revenue you are trying to grow. Best for: shops that want capacity planning anchored to true attainment.

• Pros: Free tier · Ties attainment to commissions · Real per-rep sold numbers
• Cons: A comp tool, not a field-service or planning system Verdict: Best for anchoring capacity to what reps actually sell, not their quota. ## 7. Salesforce (with capacity planning)

Salesforce is the system of record for larger, multi-location plumbing operations, and with its planning features or a capacity dashboard built on its data, you can model quota coverage against pipeline and sold-revenue attainment. Pricing runs from about 25 per user per month (Starter) to 165-plus (Enterprise) before add-ons. It will not produce a hire number out of the box — you build the model on your data — but it has the actuals (attainment, ramp, turnover) the calculation needs. Best for: larger plumbing groups that want the plan living next to the pipeline.

• Pros: System of record at scale · Flexible capacity dashboards · Rich actuals
• Cons: You have to build the model yourself · Costly once add-ons stack up Verdict: Best for multi-location groups that already run on Salesforce. ## 8. HubSpot Sales Hub

HubSpot Sales Hub, from about 20 per seat per month up to enterprise tiers, gives growing plumbing companies forecasting and attainment data plus planning tools to size coverage against a revenue goal. It fits shops running outbound or commercial-bid pipelines that need real reporting beyond a field-service app. Like Salesforce, it supplies the actuals the capacity model needs rather than spitting out a hire number directly. Best for: plumbing companies with a dedicated commercial or new-construction sales motion.

• Pros: Easy forecasting · Good for outbound and commercial pipelines · Scales up cleanly
• Cons: Overkill for a pure service shop · No hire number out of the box Verdict: Best for companies whose growth runs through a commercial sales team. ## 9. CompanyCam-plus-CRM for Estimators

For plumbing companies whose estimators sell on-site, pairing photo-documentation and proposal tools (CompanyCam plans from about 24 per user per month) with their CRM tightens how a job gets quoted and won. Standardizing the on-site estimate makes the productive-capacity number per estimator far more reliable, because every rep sells the same options the same way. It is a supporting tool rather than a planner, but it sharpens the exact input the calculator depends on. Best for: plumbing companies that want consistent in-home selling.

• Pros: Standardizes on-site estimates · Sharpens per-rep capacity input · Inexpensive add-on
• Cons: A supporting tool, not a headcount planner Verdict: Best for making your per-estimator capacity number trustworthy. ## 10. Google Sheets or Excel Capacity Model

A well-built spreadsheet is free and fully transparent — every assumption about revenue gap, capacity, ramp, and repeat rate is visible and editable. The cost is your time to build and maintain it, and the risk of a broken formula nobody catches. Many plumbing companies start here, then graduate to a calculator or platform once the model matters too much to live in a fragile sheet. Best for: owners who want full control and don't mind maintaining it themselves.

• Pros: Free · Fully transparent and editable · No vendor lock-in
• Cons: Manual to build · Fragile formulas · No guardrails against a bad assumption Verdict: Fine to start with — but the PULSE calculator is this exact model, pre-built. ## How to Choose ```mermaid
