How Many Leads Do I Need? Sales Pipeline Math for Contractors

A $2 million new commercial revenue target for 2027 works back to about 32 new buildings per rep per selling week in the worksheet below. Give the same two reps a broad list with weaker conversion at each stage and the requirement becomes 134 buildings apiece. The fit list leaves time for site walks and estimates. The broad list uses more than 53 hours per rep on research and outreach alone.

Say a Fort Worth commercial roofing contractor wants that growth from first projects averaging $47,500, sold and performed during 2027. Two reps work 46 selling weeks; the rates, time allowances and account economics below are planning assumptions for this illustration. Ground Control by PorchRocket supplies the buildings selected for the crew’s work; the sales team still earns the conversation and the contract.

I would settle the calendar before arguing about lead volume. A list can be cheap and still demand five salespeople. Start with the revenue gap, work backward, then put the resulting workload beside the hours you have.

Work backward from the revenue your crews can deliver

A $2 million revenue gap divided by $47,500 per new account requires 43 wins, with each earlier stage sized to produce those wins.

First, decide what the target measures. Use additional revenue from new accounts after subtracting retained customer work and already-signed backlog from the company goal. If the business needs $6 million and expects $4 million from those sources, the acquisition gap is $2 million.

Keep signed value separate from scheduled work. For a coating job signed in September but scheduled after the owner’s January shutdown, enter the signature in the sales year and the work in the following production year, with any deposit in its own cash column. A signature cannot fill November’s production gap. The Census Bureau’s construction put-in-place definition measures work installed or erected during a period, which is a helpful reference for separating sales activity from production timing.

The base plan counts one initial project per new building account, with a separate buying decision at each address. Repairs or later projects from the same owner stay outside this year’s acquisition target until their scope and timing are established.

Input	Base worksheet entry	What to replace in your business
New-account revenue gap	$2,000,000	Company target less retained work and signed backlog
In-year revenue per first project	$47,500	Average for the project type you intend to sell
Salespeople	2	People with protected acquisition time
Selling weeks per rep	46	Weeks after planned leave and unavailable periods
Acquisition hours per selling week	30	Outreach, visits, estimates and sales follow-up
Other working hours per week	10	Administration and existing-account work
Project gross margin	32%	Revenue less job costs, divided by revenue

Now calculate backward, rounding up at every stage:

• Wins: $2,000,000 / $47,500 = about 42.11, rounded to 43.
• Proposals: 43 / 20% = 215.
• Held site visits: 215 / 75% = about 286.67, rounded to 287.
• Decision-maker conversations: 287 / 40% = 717.5, rounded to 718.
• Buildings entering outreach: 718 / 25% = 2,872.

Those 43 projects produce $2,042,500. The small excess comes from selling whole projects.

Use the same method for service agreements, but choose the revenue period carefully. An agreement worth $12,000 with service spread evenly over twelve months contributes $6,000 to this planning year’s scheduled work if six months fall inside it. Match the account value to the target before dividing.

Count buildings and buying decisions separately

One building starts one prospect record in this worksheet; extra calls and proposal revisions do not create additional opportunities.

Set a written entry rule for each stage. A conversation means an exchange with someone responsible for the property or its purchasing process. A receptionist supplying a name is progress in contact research, but the record stays in outreach.

A meeting means a held qualification visit, with permission to inspect the relevant area and enough information to decide whether estimating is justified. Booked visits belong on the calendar. Only held visits belong in the conversion denominator used here.

A proposal means a priced scope delivered to the buying contact with a next decision date. Sending revised quantities changes the existing proposal. Count a win when the buyer authorizes the work under your contracting process, then record the scheduled production dates separately.

Keep a parent-owner field too. If the manager of four warehouses requests a single proposal covering membrane repairs across the portfolio, record the combined scope under one opportunity even though the rep has four addresses to visit and four sets of roof notes to review. Count that buying decision once.

For the first campaign, I would connect each opportunity to its building and contact records without merging their counts. That lets the owner see both the number of properties being worked and the number of purchase decisions underway.

Write loss reasons that explain the next action: outside service area, wrong roof system, no access, postponed budget or lost on the priced scope. A fit rejection should affect prospect conversion. A lost bid should affect proposal conversion. Moving both into a general dead-lead bucket hides the stage that needs attention.

Choose stage rates for each sales channel

Keep targeted and broad outbound in separate channel reports, and give referrals their own rates because introductions skip some contact-research work.

The fit-list base case uses 25% building-to-conversation conversion, followed by 40% to a held visit, 75% to a proposal and 20% to a win. Multiplying the rates gives the overall building-to-win rate:

25% x 40% x 75% x 20% = 1.5%.

That means about one win per 67 buildings entered into outreach. It does not mean one win per 67 calls. Four attempts to the same building remain one building in the denominator.

Channel	Starting count	Rates to keep separate	Decision the numbers support
Ground Control target list	New buildings assigned for outreach	25% conversation, 40% visit, 75% proposal, 20% win in the base plan	Whether selecting for fit supports the weekly quota
Broad building list	New buildings assigned for outreach	12% conversation, 30% visit, 65% proposal, 15% win in the comparison	Whether staff can absorb the extra qualification work
Owner or manager referral	Introductions received	Introduction to held visit, then proposal and win	How much introduced work can reduce outbound demand
Inbound project request	Distinct requests received	Request to qualified visit, then proposal and win	Which requests deserve estimating time

Track a cohort from its first assignment. A cohort is a group of prospects that entered outreach during the same period, so a roof proposal that closes in June still belongs with the January batch that supplied the address and paid for the first conversation. For each transition, divide buildings advancing by all buildings entering the preceding stage in that cohort, including rejections. Keep pending decisions separate until the cohort settles. Dividing this week’s wins by this week’s new leads mixes different groups.

For public opportunities, Bid Control by PorchRocket brings work from cities and school districts into a separate bid pipeline. Due dates sit beside the bid documents. Use submitted bids as that pipeline’s starting denominator. The guide to how many bids it takes to win one explains that separate calculation.

Review the first settled cohorts before raising any rate. A 20% close rate based on two wins from ten decisions deserves a smaller spending commitment than the same rate across a much larger, comparable group.

Give each rep a weekly workload that fits

The fit-list plan needs 25.7 acquisition hours per rep per week, leaving 4.3 hours inside a 30-hour acquisition budget for delays and extra follow-up.

For capacity planning, allow 24 minutes per building across the outreach sequence: four attempts averaging six minutes each, with research and recordkeeping included. Conversations have to fit inside that allowance too. Budget two hours per held visit, from departure through finished site notes. Allow another three hours per proposal for estimating and sales follow-up.

The reps handle those tasks in this model. If a separate estimator handles takeoffs while the rep walks the roof, charge those hours to the estimator’s calendar and budget before assigning the rep more buildings, because a growing stack of field notes still needs someone available to price it. Staff both sides of that handoff.

Work across both reps	Annual calculation	Annual hours	Hours per rep per selling week
Research and outreach	2,872 buildings x 0.4 hour	1,148.8	12.5
Held site visits	287 visits x 2 hours	574	6.2
Estimating and proposal follow-up	215 proposals x 3 hours	645	7.0
Total acquisition work	Sum of the rows	2,367.8	25.7

Divide 2,872 buildings by two reps and 46 weeks: about 31.22 new buildings per rep per week. Use 32 as the weekly ceiling and stop at the 2,872-building annual plan; assigning 32 every week would total 2,944. At a steady pace, four attempts per building produce about 128 attempts per rep per week, distributed across new and previously assigned records.

Do not put all 128 attempts on Monday. Reserve calling blocks around the route, and group visits by location. The outbound sales playbook for contractors gives the outreach work its own sequence.

Estimating gets a calendar block too. BLS describes cost estimators’ work as reviewing project documents and calculating costs; some visit sites. A rep cannot promise three proposal hours while spending those same hours on a roof.

Measure the allowances during the first month. If travel and access push visits to three hours, the base plan needs another 287 hours annually, or about 3.1 hours per rep per week. That nearly consumes the remaining acquisition buffer.

How much pipeline coverage does a contractor need?

A 20% proposal-dollar win rate calls for 5 times the remaining sales target in eligible proposal value, before any separate allowance for delayed decisions.

Pipeline coverage equals open eligible proposal dollars divided by the remaining booked-sales target for the same period. At $500,000 remaining, $2.5 million of proposals gives 5x coverage. At a 15% win rate, the corresponding requirement is about 6.7x.

The inverse relationship is simple: required coverage = 1 / win rate. Use a dollar-weighted win rate when proposal sizes differ. Winning four small jobs while losing one large job produces a different revenue result from winning four of five equally sized jobs.

Time matters. If the eventual win rate is 20% and 80% of eligible proposal dollars reach a decision inside the quarter at that same win rate, the combined rate becomes 16%. The $500,000 target then requires $500,000 / 16% = $3,125,000, or 6.25x coverage. Do not apply that timing reduction again if your measured rate already includes within-quarter delays.

A building awaiting its first call does not carry the same forecast weight as a delivered proposal. Under the base rates, a held visit has a 75% x 20% = 15% eventual chance of winning. A decision-maker conversation has a 40% x 75% x 20% = 6% chance. Keep each opportunity in one current stage when summing a weighted forecast.

I would review the largest open scopes individually. Before accepting a reassuring pipeline total, ask the rep which roof sections the owner has approved for pricing and which budget meeting can authorize the work, then move any scope without a decision path out of the quarter’s expected sales. Count revised proposals once.

Build seasonality and sales-cycle lag into the calendar

Start outreach before the needed contract date by the full sales cycle, then allow a separate interval for mobilization and production.

Give the base plan a twelve-week contact-to-signature allowance: four weeks for outreach, four for access and estimating, and four for the buying decision. Add six weeks between signature and the planned start. These intervals become calendar inputs, alongside the job’s own production duration.

A crew needing starts in June therefore needs outreach underway about eighteen weeks earlier. If the production schedule requires finished work in June, count backward from the finish date through production first. The contract signature alone does not settle the schedule.

The 32-building quota assumes 46 selling weeks of prospect entries can produce work inside the target year, including batches started before January. If your start date and production cutoff leave only 30 selling weeks, divide 2,872 by two reps and 30 weeks: about 48 new buildings each week. The same workload then requires 39.5 acquisition hours per rep weekly. Begin earlier or change the staffing budget.

Build monthly targets from available crew days and customer decision dates. The 46-week average sizes the team, but a rep who has four roof surveys booked during a short holiday week needs a smaller new-building assignment than a rep spending that same week in the office with open calling blocks. Move the assignment to an open week.

For HVAC campaigns, the National Weather Service explains heating and cooling degree days using daily mean temperatures relative to 65 degrees Fahrenheit. I would compare local degree-day history with the company’s service calendar when choosing outreach windows. A weather measure does not establish a property manager’s purchasing date; ask for that date during qualification.

The revenue bridge also changes account counts. If only 80% of the $47,500 first project can be performed inside 2027, count $38,000 toward that year’s target. Then $2,000,000 / $38,000 requires 53 wins. Recalculate the earlier funnel stages from 53.

Keep renewal months and replacement projects in separate rows. A signed maintenance agreement and an unapproved replacement budget should not share one expected start date or one probability.

A fit list versus a broad list, line by line

Reaching the same 43 wins requires 2,872 selected buildings in the base plan and 12,284 broad-list buildings under the weaker stage rates.

For the broad list, multiply 12% conversation conversion by 30% visit conversion, 65% proposal conversion and 15% wins. The result is 0.351% building-to-win conversion. Round upward through the reverse funnel rather than rounding the combined percentage first.

Required output or workload	Fit list	Broad list
Won first projects	43	43
Delivered proposals	215	287
Held visits	287	442
Decision-maker conversations	718	1,474
Buildings entering outreach	2,872	12,284
New buildings per rep per week, rounded up	32	134
Annual acquisition hours	2,367.8	6,658.6
Weekly acquisition hours per rep	25.7	72.4

The broad-list workload uses exactly the same time allowances: 12,284 x 0.4 hour, plus 442 x two hours, plus 287 x three hours. Even free records leave 6,658.6 hours of sales work to cover.

Fit can change each transition for a different reason. Selecting the business type gives the rep a relevant reason to approach the property. Selecting the roof material and size removes buildings the crew would reject during qualification. Keeping visits inside the service area protects time for estimates. A narrower scope also makes the proposal easier to compare with the work the buyer described.

The test is whether those improvements appear in your cohorts. Set the criteria before buying: for this roofing campaign, older membrane roofs on commercial buildings in the crew’s size band and service area. Use the commercial roof target list and the contractor ideal customer profile worksheet to record those choices.

For an HVAC department, the equivalent first filter could be buildings with visible rooftop HVAC. The funnel remains the same; the building criteria and the first offer change.

Check whether the territory holds enough target buildings

A plan requiring 2,872 fresh building prospects needs that many suitable properties after existing customers and duplicate addresses have been removed.

Count the territory before dividing it among reps. If the first search produces fewer suitable properties than the plan needs, change one input deliberately: extend the service area, add another building type, raise account value or allow more time. Record the effect on travel before expanding the radius.

The Census Bureau’s County and ZIP Code Business Patterns data provides annual statistics for establishments with paid employees by industry and geography. I would use it to compare the business mix across territories. Its establishment counts are a different unit from the building prospects used in this worksheet, so use property records to assemble the address-level campaign. The service-market sizing worksheet separates that territory count from the share you plan to win.

Separate the number of available properties from the number of distinct owners. A multi-property owner can reduce research time, but one rejected portfolio proposal can also remove several buildings from the near-term opportunity pool.

Reserve a field for when a building becomes eligible for another approach. A manager who asks for a call before the next budget meeting is future scheduled work for the rep. Reassigning that address as a fresh prospect next month inflates coverage and wastes the earlier conversation.

Buy in batches that match the contact calendar. Two reps assigned 32 new buildings each week can work through 256 buildings in four selling weeks. That gives the next order a date and a size tied to staff capacity.

Low, base and high plans for the same revenue target

The $2 million target needs between 1,594 and 5,860 buildings across these scenarios, with the low case exceeding the two-rep acquisition budget.

Keep account value at $47,500 and the win target at 43 in all three rows. The four rates below follow the same order: building to conversation, conversation to held visit, visit to proposal and proposal to win.

Scenario	Four stage rates	Required buildings	Buildings per rep per week, rounded up	Acquisition hours per rep per week
Low	20% / 35% / 70% / 15%	5,860	64	43.8
Base	25% / 40% / 75% / 20%	2,872	32	25.7
High	30% / 45% / 80% / 25%	1,594	18	17.2

The low case requires 287 proposals, 410 visits and 1,172 conversations. The high case requires 172 proposals, 215 visits and 478 conversations. Apply the same time allowances to those counts to reproduce the hours column.

Use the low row to test staffing risk and the base row to set the first budget. The high row earns a place in the forecast after comparable cohorts support those rates.

My decision rule is to fund the next batch only when the emerging stage rates and measured task times fit the 30-hour weekly acquisition budget, or when a named staffing change covers the gap. At 43.8 hours, the low case needs a correction before another large order.

Change one assumption at a time when diagnosing a miss. If conversations arrive but visits do not, examine the offer and access process. If visits arrive but estimates wait two weeks, the bottleneck is estimating capacity. Raising the lead count in that situation adds waiting records.

Budget acquisition cost against gross profit

At 43 wins and a 32% project gross margin, the base campaign produces $653,600 in gross profit before sales acquisition costs.

Each first project contributes $47,500 x 32% = $15,200 after job costs. Those costs include the field labor and travel assigned to the job, materials and other delivery expenses in the contractor’s margin calculation. They are separate from the sales budget below.

Set the annual non-list sales budget at $108,400 per rep, or $216,800 for two. Per rep, that includes $66,000 of cash compensation, $19,400 of employer benefit and payroll costs, $9,000 of sales travel, $4,000 for phone and software, and $10,000 for recruiting and training.

Salary alone understates the budget. BLS employer compensation definitions include employer-paid benefits alongside wages. Replace the worksheet’s payroll and benefit entries with the amounts your company pays, including the cost of paid time away from selling, so the acquisition calculation can carry the sales department through the weeks when no new contracts arrive. Count those costs once.

Ground Control’s November 2026 commercial price range is $10 to $20 per building. For 2,872 buildings, the property-data cost is $28,720 to $57,440. Contact research stays inside the reps’ work allowance here; no paid contact add-on is assumed.

Acquisition calculation	At $10 per building	At $20 per building
Property data	$28,720	$57,440
Data plus annual sales budget	$245,520	$274,240
Customer acquisition cost, rounded to cents	$5,709.77	$6,377.67
Gross profit remaining after acquisition	$408,080	$379,360
First-project acquisition ROI, rounded to two decimals	166.21%	138.33%

ROI equals gross profit minus acquisition spending, divided by acquisition spending. At the upper data price, that is ($653,600 - $274,240) / $274,240 x 100 = about 138.33%. Company overhead beyond the stated acquisition budget still comes out of the remaining amount.

Use the lead-list ROI guide and lead-list ROI calculator to compare a smaller order with its outreach cost. The contractor acquisition cost guide helps assign shared selling expenses. Keep renewals outside the first-project return; add them through a separate customer lifetime value calculation.

When does another sales rep pay for the seat?

A new rep with the $108,400 first-year non-list budget needs about eight additional wins at the base rates and $20 per building to cover acquisition costs.

The SBA’s break-even formula divides fixed costs by selling price less variable costs. For this hiring decision, use gross profit after delivery costs as the starting contribution per win, then subtract the additional property-data cost.

At 1.5% building-to-win conversion, data spending per win is $20 / 0.015, or about $1,333.33. Subtract that from $15,200 of project gross profit to calculate the contribution toward the sales seat.

Without rounding intermediate values, $108,400 / ($15,200 - $20 / 0.015) = about 7.82 wins. Round to eight. Rounding backward through each stage requires 40 proposals, 54 visits, 135 conversations and 540 buildings. Those buildings cost $10,800. Eight wins produce $121,600 of project gross profit, leaving $2,400 after the seat budget and property data.

That is a break-even threshold, not an attractive hiring target. Eight wins leave little room for a delayed job or extra estimating work. I would require a plan above that threshold and check the first six months’ cash demands before hiring.

The wins must be additional. If the owner has already walked the building and agreed on a scope with the manager, handing that proposal to a new rep for follow-up should not be counted as evidence that the new hire created enough revenue to cover another salary. Track who sourced the opportunity.

Capacity comes first. At 30 acquisition hours across 46 weeks, one rep supplies 1,380 annual hours. The broad-list plan’s 6,658.6 hours would require five reps after rounding up. The fit-list plan fits within two. Even at zero list cost, five reps cost 5 x $108,400 = $542,000, leaving $111,600 of the $653,600 project gross profit. The fit plan leaves $379,360 after two reps and $20 records, a $267,760 advantage. Test targeting before making the three extra hires.

If estimates are the queue, consider estimating support. If signed work exceeds production capacity, review crew scheduling. Give the new rep enough target buildings and estimating time. Have crew dates available too.

Keep a weekly worksheet tied to the next action

Record one current stage for each opportunity alongside its next action and decision date, then review cohort conversion separately from weekly activity totals.

A shared worksheet can hold the following columns without a complicated reporting setup:

• Building address and parent owner, with one assigned rep.
• Source channel, campaign batch and date outreach started.
• Fit criteria and the reason the property belongs in the campaign.
• Current stage and date it entered that stage.
• Held visit date and delivered proposal date.
• Proposed value, expected gross margin and scheduled in-year work.
• Next action, responsible person and due date.
• Decision date, result and reason for a loss or deferral.

During the weekly review, compare assigned work with available hours. Review each stalled estimate against its promised delivery date. If a rep cannot send the proposal because the owner has not supplied roof access or the estimator is waiting for supplier pricing, give that missing item a responsible person and a deadline before scheduling another visit to the same building. Clear the oldest estimating queue first.

Keep an explicit stop status for properties the team should no longer pursue. A rejected building should disappear from the active workload while remaining in the campaign’s historical denominator.

Review channel economics on a longer interval than activity. This week’s calls can be counted now. This week’s acquisition cost per win cannot be settled until the associated sales work has had time to produce decisions. Link each eventual result back to its starting cohort.

How to build the next 90 days of pipeline, step by step

Use the first 90 days to establish stage counts and task times, then order the next building batch against the calendar those results support.

1. Days 1 to 3: define the revenue gap. Subtract retained work and signed backlog from the target. Choose the first-project value for one trade and scope. Enter the work that can fall inside the revenue year.
2. Days 4 to 5: count a settled cohort. Separate outbound from referrals and public bids. Record how many buildings reached a conversation, held visit, proposal and decision. Keep unresolved records visible.
3. Days 6 to 7: select buildings in Ground Control. Pull commercial buildings in your service area using business type, roof age band, material and size for a roofing campaign, or 2+ or 5+ visible rooftop units for HVAC. Commercial records cost $10 to $20 each, with the file delivered within 48 hours after payment.
4. Week 2: assign a manageable first batch. Begin with 100 buildings, split between the two reps. At 32 new buildings each per week, introducing that batch takes about two selling weeks; follow-up continues afterward. Map the file into the worksheet and remove existing accounts before assignment.
5. Weeks 2 to 5: time the outreach work. Track research and conversation time alongside attempts. Record why buildings fail qualification. Use the observations to revise the 24-minute allowance and the criteria for the next batch.
6. Weeks 3 to 8: protect visits and estimating blocks. Measure travel through proposal delivery. Confirm who controls the buying decision and when it can happen. Add properties only at the pace the visit and estimating calendar can accept.
7. Weeks 6 to 12: inspect the unfinished decisions. Update expected start dates and identify bids waiting on access, budgets or scope changes. Keep the cohort open until its decisions arrive; 90 days is a review point, not an automatic sales-cycle limit.
8. At day 90: choose the next commitment. Recalculate low and base workloads using measured times and available conversion evidence. Increase the next order if capacity and economics support it. Otherwise adjust the offer, property criteria or staffing constraint before buying more records.

Keep the weekly quota attached to named hours throughout the test. The annual model sets a weekly ceiling of 32 new buildings per rep, but the first batch decides whether that assignment belongs on your company’s calendar.

Build the next rep’s territory with Ground Control

The fastest way to build a contractor’s target list is Ground Control by PorchRocket, with commercial building filters matched to the crew’s work. Filter commercial properties by business type, building size, roof age band and material, or visible features such as rooftop HVAC, parking areas and loading docks. Records cost $10 to $20 per building and arrive within 48 hours after payment. Wrong matches reported within 30 days receive credit back. Each property says why it matched. These are target accounts your team approaches; their owners have not requested quotes.

For the worksheet in this article, build the target list in Ground Control around the sales hours already assigned. The team gets:

• Commercial buildings in the selected area, starting with orders of 10 buildings.
• Matching reasons that let each rep start from the relevant property feature.
• Roof age band, material and size criteria for the roofing campaign, or the visible features suited to another trade.
• Optional owner information and decision-maker research, priced as add-ons, with no charge for a contact that is not found.
• CSV or Excel files that load into the team’s worksheet or CRM, with field-mapping help.
• The exact order price before payment, so the list budget can be checked against the reverse funnel.

I would start with the 100-building batch. Reserve the follow-up hours before making the next purchase. Give each rep buildings worth the visit and enough time to price the job.
