The first line is the unit the vendor bills
Here, an outsourced call center means a vendor that supplies operators, telephony, supervisors and a quality process, while you supply the product knowledge, the list and the script. A quote prices the work in one or more units. Five are worth telling apart.
- A minute of talk time. The waiting between calls stays with the vendor. Whether voicemails, ringing and dropped calls are billed depends on when the clock starts.
- An operator hour. You pay for the operator’s presence, which can include the conversations, the gaps between dials, reading the list and training. On a cold list, dialling and no-answers take part of every hour, so an hourly rate leaves that cost with you.
- A dedicated operator per month. A fixed fee for one seat, whatever the volume. Ask whether the operator works only on your account.
- A call. A price per call handled. Ask what counts as one call and how a call that needs a second contact is billed.
- An outcome, such as a qualified lead, a booked meeting or a confirmed order. The vendor takes on part of the risk that the list is poor; ask how the rate reflects it.
The rate in the quote covers one line of the invoice. Ask for the other lines before you compare quotes.
Eight lines to ask about before you compare rates
Ask whether a one-off fee covers the brief, the script, training and test calls, and whether retraining after an operator leaves is included.
Ask whether a monthly floor in hours or minutes applies, whether it is billed when your volume is lower and whether a shortfall carries over to the next month.
Ask how many revisions beyond the launch allowance are free and how many days a change takes to go live.
Ask whether evenings, nights, weekends and holidays carry a multiplier, and which hours it covers.
Ask how long the vendor keeps them, whether storage beyond that period or an export costs extra, and for the right to take the whole archive when the contract ends.
Ask whether the connector carries a development fee, a recurring fee for the data exchange or both, who writes it and what happens when you change CRM.
Ask which fields the standard report holds, and how a field of your own, such as the reason for a refusal, is priced and delivered.
Ask for the notice period, whether an early-termination charge applies, and what you receive when you leave: the scripts, the knowledge base and the recordings.
Ask four more questions before you sign. Is the rate quoted with or without tax? Is payment due a month in advance, before the first results arrive? When does the clock start: at dialling, at answer or at the first word? Does each call round up to a full minute?
Compare the cost of one result
A rate alone does not show what one result costs. Start with a pilot on a limited volume and agree in writing the numeric criteria for moving from the pilot to the full contract: the share of calls that reach a person, the conversion to the target action and the cost per lead.
Then add up everything the pilot costs:
- The rate multiplied by the planned hours or minutes.
- The one-off fees for setup, CRM integration and training.
- The minimum commitment as the floor of the invoice, even when your plan sits below it.
- The premiums that fall on your calling hours.
- Storage and export of the recordings for the length of the term.
- Your own hours: writing the brief, approving scripts, listening to calls, handling escalations and joining the weekly review.
Divide the total by the number of leads handed to sales, or by the number of calls resolved. Put the result next to the second vendor’s quote and next to your own team’s cost per result. The cost calculator works out your own team’s cost per talk minute from your inputs; multiply it by the minutes one lead or one resolved call takes.
The vendor runs the calls and you still run the project. A comparison that leaves out your own hours understates what outsourcing costs.
Three risks the rate does not price
An operator who works on several accounts may learn your script and the product only to the depth of brief training. A question outside the script, such as whether you deliver to another region, can end in a promise to check and call back, and the sale then depends on a second call. When an operator leaves, the product knowledge can leave too and the replacement may start from the same material. Keep the knowledge base on your side. Name the team in the contract and reserve your right to replace an operator. Have each newcomer pass a test call with your sales lead before taking real calls.
Unless the contract says otherwise, you may see only the vendor’s report and a sample of recordings the vendor chose, scored by the vendor’s supervisors on the vendor’s form. The billing unit also shapes incentives: a rate per minute pays more for a longer call, an hourly rate pays for presence whatever the output, and a rate per lead pays for a lead whatever its quality unless the contract defines what qualifies. Ask for three things: your own access to the recordings and the statistics, with the right to export the whole archive; your call checklist as an appendix to the contract; and a numeric service level on an inbound line, such as the time to answer and the share of calls answered.
The list, the phone numbers, any deal history and the call recordings you share move into the vendor’s systems, and your customers still look to you for them. Put the handling in a written data processing agreement: which data, for what purpose and for how long, which of the vendor’s staff can open it, whether the vendor may bring in another processor without your approval, and what is deleted or returned when you leave. Add a ban on using your list for other clients. Take these points to your counsel, who advises on which law applies. This article is not legal advice.
Which calls go to people and which to an AI voice agent
People fit the calls that cannot be scripted and where a mistake costs money: complex business negotiations, complaints and anything that needs the authority to decide. A vendor’s team can take them only if it knows your product and holds that authority.
Many calls follow one route and need a person only at an unusual branch: opening hours, order status, appointment reminders, delivery confirmations, first contact with a list you may lawfully call, a few screening questions and enquiries that arrive out of hours. An AI voice agent takes these calls and hands the unusual branch to a person.
A mixed arrangement works when the boundary is written down before launch: what the agent handles, where it stops and which team receives the call, with the context. The AI call center page describes how Benerra draws that boundary, and the article on people plus AI agents looks at where the line falls in your own call center.
Ask an AI voice agent vendor the same questions
The eight lines apply to an AI voice agent quote as well. Ask whether the per-minute rate is all-in, or whether telephony, speech recognition and the language model are billed on top. Ask whether concurrent calls are capped, what happens beyond the cap and what becomes of your call data when you leave.
Benerra publishes the answers to part of this list. Bene Hotline, the inbound line, has a base rate of EUR/USD 0.20 per minute of talk time, excluding VAT. Volume discounts run to -25% across the tiers, and Latin America is priced in USD at half the European Bene Hotline rate. On Bene Hotline, concurrent calls are answered rather than queued, up to the capacity agreed for your line. Every call comes back as a transcript by speaker and timestamp, with the audio recording.
On data, the Benerra data protection policy says that Benerra processes its clients’ call data as a processor on their documented instructions, brings in a sub-processor only with the client’s prior authorisation, general or specific, given in writing, and deletes or returns the data at the client’s choice when the service ends, unless the law requires storage.
The security and compliance page adds that, by default, speech recognition, the language model and speech synthesis run on servers Benerra operates, so no third-party speech provider receives the call audio. If a project needs another provider, Benerra tells the client which layer changes, and where that provider processes data, before go-live.
Scoring every call closes the gap that a vendor’s sample leaves. Locator, Benerra’s speech analytics, scores 100% of your recorded calls against a checklist you set, whereas manual QA in our own operations reviews under 5% of calls. It needs two inputs, the recordings and the checklist, so whether you hold the recordings of an outsourced team is a contract question.
Put the same questions to Benerra
Ask Benerra in writing about every line its published terms leave open, as you would ask any vendor, and keep the answers with the contract.
Run the comparison this week
- Ask each vendor for the full price list with every appendix, and for the unit it bills.
- Put the eight lines in a table, one column per quote, and mark every answer that is missing.
- Add your own hours for the length of the pilot.
- Divide each total by the number of results the pilot should produce.
- Agree in writing the numeric criteria for moving from the pilot to the full contract, and ask for your own access to the recordings.
Keep the table. It becomes the template for every renewal and for every new vendor.
