A telemarketing company is a firm you pay to make or take sales calls on your behalf. The label hides three different businesses. Call centers rent you agent hours, appointment-setting shops sell meetings, and outbound agencies sell a plan for reaching a market. To compare them fairly, you need to know which one you are buying and who is liable when a caller breaks the rules.
Work through it in five steps:
- Pick the business you actually need.
- Choose the engagement model that puts the risk where you want it.
- Put every provider through the same 10 questions.
- Check who is liable for rule breaks. In the US and the UK, the answer often includes the company that hired the caller.
- Write each side's compliance duties into the contract, then judge results on next steps, not dials.
Disclosure: I do not sell telemarketing. My team books meetings mostly through cold email and LinkedIn, with no cold calling, so this guide ranks nobody. Directories are fine for a shortlist, and this guide gives you the tests to cut that shortlist down yourself.
What does a telemarketing company actually sell?
Seat rental. You pay for agent hours. The provider supplies callers, a dialer and a supervisor. You supply the script, the list and the definition of a good call. The invoice arrives whether anyone books or not.
Appointment setting. You pay for booked meetings. Each slot is worth exactly as much as the meeting definition you both signed.
Outbound agency. You pay for a plan to reach a market. The phone may run next to email and LinkedIn, or be left out.
Then comes the inbound and outbound split. Inbound telemarketing answers calls that your website, ads or mailings produced. Outbound dials people who never contacted you. If you sell B2B, you most likely want outbound, and that is where the legal exposure sits. If you are really choosing between a calling vendor and a meeting-booking team, the comparison of telemarketing appointment setters and agencies is the better starting point.
Which engagement model fits your situation?
What separates the models is who pays when nothing gets booked.
| Model | What you pay for | Who carries performance risk | What you should own afterwards | Typical lock-in |
|---|---|---|---|---|
| Hourly seats | Agent hours, often plus setup and training | You, almost entirely | Your lists, call recordings, call notes | Minimum hours or months per seat |
| Pay per meeting | Each meeting that meets the written definition | Shared, if the definition is on paper | Meeting records and the prospect data behind them | Often a minimum volume or term |
| Monthly retainer | A team and a plan for the month | Mostly you, until results show | Lists built for you, scripts, sequences, CRM history | Notice period, sometimes a minimum term |
| Hourly plus performance | A lower base rate plus a bonus per meeting or deal | Split by the formula | Same as hourly, plus outcome reports | Usually tied to the seat minimum |
| Warm-calling add-on | Calls to people who replied, engaged or opted in | Lower, because the person already knows you | The reply history behind each call | Usually follows the main engagement |
How to choose:
- Hold off on pay per meeting until you can write a good meeting down in three lines. Without a written definition, the provider decides what counts.
- Hourly seats work when you already have a converting script and a manager with spare hours. You buy capacity, and the judgment stays with you.
- Pay for targeting work before dials if you do not yet know which titles buy. Look at your past deals, find out who actually signed, and target that title, not a generic "manager". Calling the wrong list harder will not fix it. Our lists and targeting FAQ shows how we build lists.
- Ask what a setup fee produces, and whether you keep it. Scripts, lists and call guides you paid for should stay yours.
At the time of writing, I could not find a credible published price list for hourly seats, pay-per-meeting deals or calling retainers. Providers quote privately and in different units. The one hard number under any seat price is the caller's wage, covered in the FAQ below. Ask every provider to quote in the same format, then line the quotes up the way you would when you compare agency proposals.
How do you score a telemarketing provider before you sign?
Ask these 10 questions on the sales call and write each answer down. A fail on question 4, 5 or 8 ends the process. For agencies and appointment-setting shops, so does a fail on question 1.
| # | Question | Pass | Fail |
|---|---|---|---|
| 1 | Who exactly will make the calls? | Named people you can look up, with real sales history | "Our team", with no names |
| 2 | How senior are they, and how many clients does each carry? | A clear count, with senior people on your account | Juniors or interns, or a dodged count |
| 3 | Where does the calling list come from? | Named sources and a build process for your market | "Our database" |
| 4 | How do you screen the list before dialing? | A documented check against each country's opt-out and register rules, with records kept | "We're compliant" |
| 5 | Can I listen to every recording? | Full access, any time | Selected highlights only |
| 6 | How often do I get reports, and what is in them? | Weekly, showing conversations and next steps | Dials and hours only |
| 7 | What counts as a meeting? | A written definition you can edit | "A slot on your calendar" |
| 8 | Who owns the data when we stop? | You own lists, recordings, notes and CRM records | The provider keeps them |
| 9 | How do I leave? | Short notice, no automatic renewal | Long minimum term that renews by default |
| 10 | Can I speak with two current clients? | Yes, in a market close to yours | Logos on a slide only |
Question 1 matters most to me. Plenty of agencies are faceless: a brand name with nobody visible behind it. In shops like that, the calls often go to students, interns, junior reps or offshore staff, talking to your buyers in a second language. And nobody senior picks up when it goes wrong.
The test for agencies and appointment-setting shops takes two minutes. Ask who will make your calls, then look those people up. If they are not on LinkedIn, you have your answer.
A seat-rental center often cannot name agents before signing. Ask for the supervisor's name and the agents' track record instead.
A review that says "friendly and responsive" is about the account manager. It tells you nothing about results. A review worth reading names the market, the meetings or pipeline produced and the period. When you call the references from question 10, ask how many meetings turned into a second conversation.
Who is liable when the provider breaks the rules?
In both countries the rules reach the company that hired the caller. This is not legal advice, so speak to a lawyer in each country you plan to call.
| United States (at the time of writing) | United Kingdom (at the time of writing) | |
|---|---|---|
| Who is liable | The seller and the telemarketer. Anyone who gives substantial help while knowing, or consciously avoiding knowing, about violations also breaks the FTC's Telemarketing Sales Rule (16 CFR 310.3) | You and the contractor are both responsible. The Information Commissioner's Office (ICO) usually acts against you, the company that ordered the calls (the "instigator") (ICO guidance) |
| B2B treatment | Most calls to businesses are exempt from the rule, except its misrepresentation provisions. Calls selling nondurable office or cleaning supplies stay covered, minus the Do Not Call Registry and record-keeping sections (16 CFR 310.6) | Covered, with lighter rules for calls to companies than to individuals. The ICO treats sole traders and some partnerships like individuals |
| Key ban | False or misleading statements made to get someone to pay (16 CFR Part 310). Consumer sales calls are barred before 8 a.m. and after 9 p.m. local time (FCC) | Marketing calls are banned to numbers on the Telephone Preference Service (TPS) or Corporate TPS register, and to anyone who has said they do not want them (Privacy and Electronic Communications Regulations (PECR), regulation 21). Caller ID must not be hidden (PECR regulation 24) |
| Penalty reference | Private lawsuits under the Telephone Consumer Protection Act (TCPA) over autodialed or prerecorded calls: $500 per violation, and a court may raise the award to three times that for willful or knowing violations (47 U.S.C. 227(b)(3)) | ICO enforcement, usually against the instigator |
| Record keeping | Keep the listed records for 5 years (16 CFR 310.5) | Records of consent: what, when and how |
The 5-year period is recent. In its April 2024 final rule, the FTC said two years was no longer always enough time to complete its investigations, so it raised the retention period (Federal Register, April 2024). Check that your provider's retention policy reflects the change.
The B2B exemption is narrower than many providers suggest. A call to someone at work asking them to buy for personal use is not exempt (FTC guidance). Misrepresentation was never exempt either. A caller who invents a referral, a deadline or a discount in your name breaks the rule even on a clean B2B list.
"Consciously avoiding knowing" is the phrase that should worry you as the buyer. If you suspect your provider cuts corners and choose not to look, the rule can still reach you. Moving the seats abroad does not help either: FTC guidance says the rule applies even when calls are made from outside the United States, as long as they go to consumers in the US (FTC guidance).
Which contract clauses should a telemarketing agreement include?
The ICO tells companies that hire a telemarketer to set the contractor's responsibilities out in a written contract, and warns that an indemnity is no substitute for proper checks (ICO guidance). Clauses to ask for, with wording you can paste into your redline:
- Meeting definition. "A qualified meeting is a scheduled call with a person holding one of the job titles in Schedule A, at a company meeting the criteria in Schedule B, who has accepted the calendar invite. Meetings that fail any condition are not billable."
- Data ownership. "All lists, call recordings, call notes and CRM records created under this agreement belong to the Client and will be delivered in a usable export within 10 business days of termination."
- Term and notice. "Either party may end this agreement with one month's written notice. There is no minimum term and no automatic renewal."
- Compliance duties per party. "Before dialing, the Provider will screen every number against the register and opt-out rules of each country called, keep a record of each screening, and act on any opt-out request immediately. The Client will supply its own suppression list of past opt-outs before launch."
- Audit right. "The Client may request screening records and call recordings for any campaign period, and the Provider will supply them within 5 business days."
- Indemnity with stated limits. "The Provider will indemnify the Client against fines, claims and costs caused by the Provider's breach of clause 4, up to [agreed cap]." Keep checking the provider's work anyway, because the ICO says an indemnity is no substitute for proper checks.
My own client contracts have no minimum term and a one-month notice period, as in clause 3. I still recommend staying at least 3 months, because outbound needs time to gather feedback, adjust and improve. Across the industry, getting outbound fully working takes about 6 months. A long auto-renewing term with no performance exit mainly protects the provider's revenue.
What red flags should end the sales call?
End the call if you hear any of these:
- A guaranteed number of meetings, with no meeting definition on paper
- Performance stats with no sample size, period or market named
- "Fully compliant", with no rule named and no answer on how numbers are screened per country
- No access to call recordings
- A long term that renews automatically, with no exit if performance falls short
- A large upfront fee for a playbook they cannot show working recently
The last one is common. Some SDR shops charge a big monthly fee upfront, run playbooks that worked three years ago and deliver nothing. If you are weighing an outsourced SDR team instead of a calling vendor, check what an SDR agency really delivers before you hire one. Whichever vendor you pick, the questions to ask before you hire an agency apply just as well.
More volume cannot rescue broken foundations, and cheap dialing shops sell volume. For one client we changed only the foundations, the things buyers check before they reply, and nothing else. Same market, same people sending. The reply rate rose 571% in 60 days.
Why can more booked meetings make results worse?
Booking a call and closing a deal are separate jobs, and most telemarketing companies do only the first. In my experience a weak close rate does not recover with extra volume. It usually slips further as the calendar fills and each call gets less preparation. Founders count the 2 or 3 contracts they signed. I count the 97 or 98 prospects they lost on the way.
So before you buy a calling team, check whether you convert the meetings you already have. In our email and LinkedIn campaigns, the third follow-up, sent with real time between touches, is usually what works best. By the same logic, one round of calls with no follow-up is a thin test of a market.
Then change what you measure. Dials and booked slots show activity, and activity does not pay invoices. Track meetings that reached a next step: a proposal, a second call, or a decision-maker joining. Booked and showed are two different numbers, so ask the provider to report both. And put one person in charge of replies and confirmations on your side, so no interested prospect gets missed.
Judge on the right timeline too. Sales cycles in B2B commonly stretch to 6, 9 or even 12 months, so deals from first-month meetings may close only four months or more afterwards. A provider judged on month one gets fired too early or kept for the wrong reasons.
Where does my agency fit, and where does it not?
Every phone figure here comes from a regulator or a government source, because we have no phone results of our own.
If your buyers pick up the phone and you need dialing at volume, a telemarketing company is the right purchase. Take the 10 questions and the six clauses to your next provider call. A provider that answers both plainly has earned a trial. If you run a call center yourself and want to win clients, selling BPO services is a different job. If you would rather get meetings through email and LinkedIn, see our appointment setting service.

Questions buyers ask about telemarketing companies
What do telemarketers get paid?
O*NET OnLine, using Bureau of Labor Statistics data, puts the 2025 US median wage for telemarketers at $17.04 an hour, or $35,450 a year (O*NET). That is the caller's pay. A seat price also covers supervision, software, data and the provider's margin, so ask each provider to itemize the gap between the two.
How many calls can a telemarketer make per day?
I could not find an official daily figure, and provider claims rarely state a sample or period. The real number depends on list quality, conversation length and the dialing setup. At the time of writing, the one hard US legal limit is on predictive dialers: no more than 3 percent of live-answered calls may be abandoned per campaign, measured over 30 days (47 CFR 64.1200).
Can a telemarketing company use AI voice agents?
In the US, the FCC treats calls using AI-generated voices as unlawful without the consumer's prior consent, unless an exemption applies (FCC). Prerecorded telemarketing calls also need prior written consent and must offer an opt-out at the start of the message. Ask any provider selling AI callers which exemption it relies on and who holds the consent records.
How soon does a newly registered UK number become off-limits?
The calling ban applies from 28 days after a number is listed on the TPS or Corporate TPS (PECR regulation 21). A registered business can still tell one specific caller that it does not object to that caller's calls. Ask your provider how often it re-screens lists and how it records those non-objection notices.
