By The argument about exclusive vs shared cleaning leads usually gets stuck on price. Shared leads look cheap. Exclusive leads look expensive. Both statements are true at the lead level and both miss the point, because nobody runs a cleaning business on leads. You run it on signed contracts. This post does the arithmetic so you can decide with your own numbers.
If you want the plain definitions and a side-by-side of features, read our exclusive vs shared leads comparison. For how exclusive leads work at LeadWharf, see exclusive cleaning leads. This post is only about the math.
What is the difference between exclusive and shared cleaning leads?
An exclusive cleaning lead is sold to one company only. A shared cleaning lead is sold to several companies at the same time, and each one pays for it. With a shared lead you are competing for the prospect from the moment it arrives. With an exclusive lead the competition is only the prospect's current cleaner and whoever they find on their own.
Market prices reflect this. Janitorial leads average $18 to $55 per lead, with most under $60, according to ProMatcher. One exclusive provider lists commercial cleaning leads at $54.99 each from organic search as of September 2026. Exclusive leads with deeper qualification cost more. The question is whether the extra closing power pays for the extra price.
What formula decides which lead is cheaper?
The formula is cost per contract = price per lead ÷ close rate. Run it for both lead types and compare. You can also shortcut it:
An exclusive lead is the better deal when (exclusive price ÷ shared price) is less than (exclusive close rate ÷ shared close rate).
In words: if exclusive leads cost three times as much, they need to close more than three times as often. That single comparison answers most of the debate.
A simple example (hypothetical numbers)
These numbers are invented to show the method. They are not market close rates and not anyone's results.
| Shared | Exclusive | |
|---|---|---|
| Price per lead | $40 | $150 |
| Close rate | 5% (1 in 20) | 20% (1 in 5) |
| Leads per contract | 20 | 5 |
| Lead spend per contract | $800 | $750 |
The exclusive lead costs 3.75 times as much and closes 4 times as often, so it comes out slightly cheaper per contract. Change the exclusive close rate to 15% and the answer flips: $150 ÷ 0.15 = $1,000 per contract, more than the shared route. The math is sensitive to close rate, which is why measuring your own is worth more than any rule of thumb.
How does the number of buyers affect your close rate?
The more companies receive a shared lead, the lower your expected share of wins, unless you are consistently faster or better than the rest. If a lead goes to four companies and all four respond well, a fair share is about one win in four of the deals that close at all. Being first or best lifts your share. Being slow drops it toward zero.
This table shows how the math shifts as a shared lead goes to more buyers. It assumes, for illustration, that 25% of leads end in a contract with someone and that you win an equal share.
| Buyers per lead | Your expected close rate | Leads per contract | Cost per contract at $40 a lead |
|---|---|---|---|
| 1 (exclusive) | 25% | 4 | $160 |
| 2 | 12.5% | 8 | $320 |
| 3 | 8.3% | 12 | $480 |
| 4 | 6.25% | 16 | $640 |
| 5 | 5% | 20 | $800 |
The price of the lead did not change down the table. The number of competitors did. Ask every seller how many companies receive each lead, and put that answer into this table.
How much does response speed change the math?
Response speed changes the math a lot, because on a shared lead the first serious caller often wins. In a study of 1.25 million sales leads, firms that tried to contact a prospect within an hour were nearly seven times as likely to qualify the lead as firms that tried an hour later, and more than 60 times as likely as firms that waited 24 hours or more. The same study audited 2,241 companies and found an average response time of 42 hours among those that responded within 30 days.
What this means for your numbers:
- If you respond in minutes, your close rate on shared leads can sit well above your fair share, and shared leads may pay.
- If you respond in hours or the next day, your share of shared leads collapses, and each one mostly funds a competitor's win.
- On exclusive leads, speed still matters because interest cools, but nobody else is racing you to the same phone number.
What hidden costs change the comparison?
The hidden costs are the time you spend on leads that never close: calls, voicemails, drives, walk-throughs and quotes. Those costs grow with the number of leads you need per contract, so they hit low-close-rate sources hardest.
Add them in with a second example (again hypothetical):
| Shared | Exclusive | |
|---|---|---|
| Leads per contract | 20 | 5 |
| Phone time per lead (20 minutes at $40 an hour) | $267 | $67 |
| Walk-throughs per contract | 6 | 2 |
| Walk-through cost (2 hours at $40 each) | $480 | $160 |
| Lead spend per contract | $800 | $750 |
| All-in cost per contract | $1,547 | $977 |
When the exclusive lead and the shared lead looked almost even on lead spend, the sales time made the gap large. Your hourly cost of selling might be higher or lower. Put it in.
Does qualification matter as much as exclusivity?
Qualification matters as much as exclusivity, because an exclusive lead that is out of your area or only wants a one-off clean is still a wasted lead. Three checks do most of the work:
- Area. Is the building inside the zone you actually serve?
- Recurring need. Has the contact said they want regular cleaning at a frequency and size worth your time?
- Decision-maker. Is this the person who signs, with a direct line?
A lead that passes all three closes more often, whether it is shared or exclusive. A lead that fails one mostly does not. See how to qualify a cleaning lead for the questions to ask on the first call.
How does contract value change the answer?
Contract value changes the answer because it sets how much a lost lead really costs you. On small, one-off jobs, the gap in cost per contract between shared and exclusive leads can be a large share of the job's profit, so cheap volume is tempting. On a recurring contract cleaned several nights a week, the same gap is small next to the profit the account brings in over a year or more. That is why owners chasing nightly janitorial accounts tend to care most about close rate and decision-maker access, and owners chasing quick one-off cleans tend to care most about price per lead. Put your own average monthly contract and retention into the cost per lead calculator to see where the line falls for you.
When are shared leads the better choice?
Shared leads are the better choice when your team answers within minutes, your price is competitive, and you want volume more than relationship. They can also suit one-off services where buyers pick quickly. Some owners use shared leads to fill gaps in a crew's schedule and exclusive leads to build the recurring base. That is a reasonable mix.
How do you run this test in your own business?
Run it by tracking every lead from every source in a simple sheet for at least a few months. Use this template:
Lead source tracking sheet (template)
| Column | What to record |
|---|---|
| Date received | Day and time the lead arrived |
| Source | Seller, channel or campaign |
| Exclusive or shared | And how many buyers, if known |
| First contact time | Minutes from arrival to first call |
| Reached decision-maker? | Yes or no |
| Walk-through booked? | Yes or no, with date |
| Quote sent? | Amount and date |
| Result | Won, lost, or open |
| Monthly value | If won |
| Time spent | Rough hours on this lead |
At the end of each month, calculate cost per contract for each source. Our cost per lead calculator does the arithmetic, and how much do commercial cleaning leads cost covers market prices by lead type.
Where does LeadWharf fit?
LeadWharf sells exclusive leads only. Each lead goes to one company, your area is locked while you are with us, and every lead must clear the three checks above or it is credited. There is a one-time setup and then a flat fee per qualified lead, with no monthly charge. The fee depends on your territory and is given on a call, so you can plug it into the formula above with your own close rate. Book a call to get the number for your area, or read pay per lead cleaning leads for how the model works.
