LeadWharf and Callbox both find commercial buyers for you, but they are built for different buyers. Callbox is a global B2B agency that runs multi-channel campaigns for companies in many industries, cleaning among them, and books meetings for your sales team. LeadWharf works on janitorial and commercial cleaning leads, writes to decision-makers in your name, and hands you each qualified contact to call. If you searched "LeadWharf vs Callbox" or "Callbox janitorial", the real choice is between funding a campaign team by the quarter and paying for one qualified lead at a time.
Every fact about Callbox below comes from its own website or its Clutch profile, as of October 2026. Agencies change their terms, so confirm anything that matters before you sign.

How does Callbox work?
Callbox runs outbound campaigns for B2B companies and books qualified sales meetings with their prospects. Its homepage describes it as a global outsourced lead generation and sales support provider, founded in 2004, that pairs AI tools with human sales development reps (SDRs). It lists phone, email, LinkedIn, social, chat, webinars and events as channels, and says it has teams in the US, UK, Australia, Singapore, Malaysia, Hong Kong and Colombia. Its services include lead generation, appointment setting and outsourced SDRs, account-based marketing, and event and webinar marketing.
Its pricing page builds each program around a "pod". One pod includes a dedicated SDR, a multi-channel outreach cadence, enriched contact data, a campaign manager and weekly performance reports. The page lists phone, email, LinkedIn and web retargeting as the pod's channels, and includes its own CRM.
In practice, a cleaning company hands Callbox a target: an area, building types and the job titles that buy cleaning. Callbox's team works that list across channels and puts appointments in front of your sales staff.
What do Callbox's janitorial case studies show?
Callbox's janitorial case studies show long, managed campaigns for commercial cleaners, with results stated in appointments and leads. These are Callbox's own published claims; we have not checked them independently.
Long Island janitorial firm. Callbox describes a family-owned commercial cleaning company in Bohemia, New York, that hired it in January 2015 because it had limited staff for outbound prospecting. The campaign targeted large companies in Nassau and Suffolk counties, reaching general managers, operations and maintenance managers, facility and purchasing managers, owners and school directors. Over what the case study calls a 31-month campaign, Callbox reports 622 qualified appointments, 933 completed leads and 1,047 net new prospects.
California campaign for a Florida cleaner. A second case study covers a commercial cleaning company headquartered in Miami Springs, Florida, targeting facilities managers, office managers, general managers and owners in San Francisco and Los Angeles. Callbox reports 22 sales appointments, 59 marketing qualified leads and more than 90 net new prospects.
A client's own view. On Callbox's site, the sales director of MP Service Group, a janitorial company in Port St. Lucie, Florida, reviewed a campaign that began in September 2020. Writing in February 2021, he scored Callbox 4.0 out of 5, said the company kept meeting and closing new accounts during COVID-19, and praised the support. His one complaint: appointments were sometimes set an hour or two apart at sites a long drive from each other.
The takeaway is fair: Callbox has run cleaning campaigns, some for years, and produced meetings at volume. What the case studies do not show is the cost per appointment or how many became signed contracts, so ask for both.
What does Callbox cost?
Callbox does not publish a fixed price, but it does publish estimates. As of October 2026:
- Its pricing page shows an estimated quarterly investment of $16,000 to $32,000 for one pod, with exact pricing given after a consultation. It says pricing depends on target industry, campaign complexity, geographic reach and sales cycle length, and that its subscription pricing has "no hidden fees". Contract length is agreed with its team.
- Its pricing FAQ says clients spend $20,000 to $40,000 a quarter, driven by the staff assigned, languages, target regions and the customer data involved.
- On Clutch, minimum project size and hourly rate are listed as undisclosed. The most common project size across 101 reviews is $10,000 to $49,999.
So plan on a committed quarterly budget before the first meeting lands. That is a normal shape for a managed agency, and it buys a team working your market every week. Our page on pay per lead vs retainer walks through how those two payment models change your risk.
What do Callbox reviews say?
Callbox's Clutch profile shows a 4.6 overall rating from 128 reviews as of October 2026, which is a strong record for an agency of its size. Clutch lists 1,000 to 9,999 employees and a Los Angeles headquarters. Cost is the lowest-rated category at 4.3. Recurring requests in the reviews are deeper reporting and analysis, more consistent lead fit, and more flexible pricing, and some clients saw weaker results in non-English markets. Callbox's own homepage cites a G2 rating of 4.4 from more than 90 reviews.
How does LeadWharf work?
LeadWharf sends you janitorial and commercial cleaning leads that each pass three checks, and you pay per lead. We start with a short call to agree your patch: the area, the buildings you want and the smallest job worth your time. Then we learn your pitch through a short form, build a dedicated and warmed email sending setup, and find and verify the decision-makers in that area.
The outreach goes out in your company's name. When someone replies, we qualify them against three checks:
- The building is in your area. Inside the service area you drew.
- They want regular work. In their own words, at your frequency and job size.
- You get the person who signs. A named decision-maker with a direct line.
A lead that clears all three arrives with the company and building, the contact's name and role, direct phone and email, what they need, how often and when they want to start. You book the walk-through and write the quote. A lead that misses any check is credited, with no argument. Pricing is a one-time setup, then a flat fee per qualified lead, quoted for your territory. The full sequence is on how it works.
Judge LeadWharf on your first lead: if it misses a check, you are not charged.
Generalist B2B agency vs cleaning specialist: what changes?
The main difference is how much of the job the vendor already knows before your campaign starts. A generalist like Callbox brings scale, multiple channels and process built over many industries. You brief it on what a good cleaning prospect looks like, and its team turns that into lists, scripts and cadences. That breadth is useful if you sell several services, run in many cities or want phone and LinkedIn alongside email.
A specialist starts with the cleaning buyer already defined. LeadWharf's qualifying standard is written for cleaning: recurring work, your frequency, your job size, the person who signs. That keeps the brief short and the handoff consistent.
The second difference is who owns the first conversation. An appointment setter talks to the prospect first and passes along a meeting. With LeadWharf, the prospect has only heard from your company, and your call is the first live voice. Neither is right for everyone. Our pay per lead vs appointment setting comparison covers that choice in more depth, and in-house sales vs outsourced lead generation helps if you are also weighing a hire.
Where Callbox is the better choice
- You are a larger, multi-site contractor. A dedicated SDR and campaign manager suit a company with sales staff ready to run several meetings a week across a wide region.
- You want multi-channel outreach. Phone, email and LinkedIn together reach some facility managers who ignore a single channel.
- You want a long, managed campaign. Callbox's Long Island case study ran for 31 months. If you think in years and want weekly reporting, that structure fits.
- You want meetings booked for you. If nobody on your team will make the first call, a setter removes that step.
- You sell more than cleaning. A generalist can run campaigns for adjacent services under one program.
Where LeadWharf is the better choice
- You want to pay per result, not per quarter. One-time setup, then a fee for each qualified lead. No retainer, no contract, no notice period.
- You want recurring intent confirmed. Every lead has said they want regular cleaning at your frequency, not just that they would take a meeting.
- You want your company to be the first voice. Outreach goes out in your name and you make the booking call, which also lets you plan routes so walk-throughs are not scattered across a county.
- You want your territory held. One company per area, locked while you stay. Each lead goes to you alone and is never resold.
- You want a short setup. One call to agree the patch and a short form for your pitch.

Questions to ask either company
- What is the total spend before my first signed contract, not my first meeting?
- How do you define a qualified appointment or lead, in writing?
- Will I reach the person who signs the cleaning contract?
- Has the prospect said they want recurring cleaning, or only agreed to talk?
- Can a competitor in my area buy the same campaign or the same contacts?
- What happens if a meeting is a no-show or a lead is the wrong contact?
- How are appointments routed so my estimator is not driving across the region between them?
- What is the minimum commitment, and how do I stop?
Which should you choose?
Choose Callbox if you are a larger cleaning contractor with a sales team, a quarterly budget and a plan to run a long, multi-channel campaign across several markets with meetings booked for you.
