The short version
Choose the operating model before the provider
A lead generation company can be an agency running media in your accounts, a business generating first-party enquiries through brands it owns, an aggregator reselling leads created elsewhere, or a call-centre team booking appointments. Those are not interchangeable services.
We recommend starting with the outcome your sales operation needs. Decide whether you want leads, qualified appointments or a suitable acquisition-based arrangement; agree the products, locations and volume; then compare providers using contact, appointment and sale outcomes rather than headline cost per lead alone.
01 · Define the purchase
Four businesses can all call themselves a lead generation company
Depending on the market, the same supplier might be described as a lead generation agency, a lead generation company or a provider of lead generation services. We would not choose on the label. We would first establish whether the supplier manages campaigns, supplies consumer enquiries, provides qualified appointments or shares the risk of a completed acquisition.
In our experience, the right model is usually determined by the capability already inside the buyer’s business. A company with an experienced contact centre may want exclusive leads delivered directly to its team. A company without that resource may gain more from appointments that have already been contacted and booked. A larger strategic partner with dependable outcome reporting may be suitable for an acquisition or revenue-share arrangement.
Before making a shortlist, write down where you want the provider’s responsibility to end and your team’s responsibility to begin. That single decision makes pricing and performance comparisons much clearer.
| Provider model | What the buyer receives | Buyer retains | Question to resolve first |
|---|---|---|---|
| Managed acquisition agency | Campaign management, creative and reporting | Media budget and sales conversion | Which management fee, media budget and performance measures apply? |
| First-party lead generator | An enquiry generated through the provider’s own campaign or brand | Contact, appointment and sales process | Which lead criteria, CPL, volume and exclusivity apply? |
| Aggregator or marketplace | A lead sourced from one or more external generators | Most downstream qualification and sales work | How recently was it generated and how many buyers receive it? |
| Appointment-setting provider | A contacted and booked prospect | Meeting, quote and sale | What counts as a valid, attended, cancelled or replaceable appointment? |
02 · Understand the campaign
Understand how the provider generates your leads
We recommend asking whether the provider creates the enquiries through campaigns it controls or buys them from elsewhere. This affects how quickly targeting, creative, questions and filters can be changed when your sales feedback identifies an opportunity to improve.
At Adfluential, we own and manage the brands and campaigns that generate our leads. That allows us to show buyers the relevant journey, agree the information collected and use downstream outcomes to refine the campaign. When comparing providers, we would look for the same ability to explain and improve the route from advert to enquiry.
The strongest setup begins with an honest view of your products, service areas, sales capacity and the customers you are best placed to serve. A provider cannot build the right campaign if those requirements remain vague.
What we ask a buyer to agree
- The products and services the sales team can quote.
- The postcodes or regions the business can cover.
- The useful qualification questions for the first conversation.
- The daily or weekly volume the team can respond to properly.
- The contact, appointment and sales outcomes available for feedback.
What a provider should explain
- Which channels and consumer brands generate the enquiries.
- Which questions, checks and matching criteria are used.
- Whether leads are exclusive or supplied to several buyers.
- How quickly leads or appointments reach the sales team.
- How buyer feedback changes targeting and campaign decisions.
03 · Match the opportunity
Look for a campaign that matches what you sell
We recommend assessing the actual customer journey rather than treating every form submission as the same product. A solar installer may want homeowners comparing panels and battery storage, while a window company may need separate journeys for replacement windows, doors and conservatory work.
Ask to see how the advert and page describe the product, which questions are asked and what happens after the enquiry. This tells you whether the campaign is attracting the sort of conversation your team is equipped to handle.
Relevance also affects the first call. When the salesperson receives the product and project context used in the campaign, they can start with the customer’s actual request instead of repeating a generic qualification script.
04 · Agree the commercials
Determine commercials before commencing
We recommend agreeing the commercial model only after both sides understand the sales process. Paying per lead works well when the buyer has a team ready to contact and qualify enquiries. Paying for appointments moves more of that work to the provider. A cost-per-acquisition or revenue-share arrangement moves payment to the completed outcome and is normally most suitable where sales and revenue feedback can be shared reliably.
For CPL, agree the cost, products, locations, volume, exclusivity and the criteria applied before delivery. For appointments, agree what qualification and confirmation take place, what counts as a valid booking and how cancellations are handled. For an acquisition model, agree the qualifying sale, payment timing, cancellations and the outcome information both sides will use.
The lowest initial unit price is not always the lowest acquisition cost. We would compare the model against your contact capacity, appointment rate, sale rate, average order value and margin before deciding which option offers the best fit.
05 · Understand exclusivity
Exclusive should describe supplier behaviour precisely
At Adfluential, an exclusive lead is supplied to one matching buyer rather than deliberately shared between several competing businesses. The customer can still carry out their own research, but we do not create extra competition by reselling the same enquiry.
We recommend confirming whether a quoted CPL is for exclusive or shared supply because the sales experience is different. Shared leads can cost less, but the buyer may need to compete with several near-simultaneous calls. Exclusive leads usually give the receiving team a cleaner opportunity to have a useful conversation.
06 · Plan delivery and follow-up
Make sure delivery fits your sales team
We deliver leads in real time because consumer interest is most useful while the request is still current. The practical setup can remain simple: leads can reach a buyer through its preferred system, by email or through a shared sheet, depending on the campaign and team.
The more important question is who will respond and whether they have enough capacity. We recommend setting volumes around the number of enquiries the team can contact properly, rather than accepting the largest number available and allowing follow-up to slow down.
Your salesperson should also receive the product, location and qualification answers collected during the journey. That context makes the first conversation more relevant and gives the buyer useful feedback to return to the campaign team.
07 · Compare economics
Move past CPL as soon as the data allows
We use CPL to understand acquisition efficiency, but we do not believe it should be the final measure of a campaign. A lower CPL can still produce a higher cost per sale if fewer people can be contacted, fewer fit the product or the same leads are shared between several businesses.
We recommend measuring the deepest outcome your business can return consistently. Start with contact and appointment rates, then add quotes, completed sales, revenue and margin where they are available. Earlier stages help explain performance; later stages show whether the commercials work.
Why downstream evidence matters
Adfluential’s published window campaign reports the whole chain
Our window lead generation case study reports 10,000 leads per month, 1,222 booked appointments, 349 closed sales, £2.375m in revenue and an 8.3x return on spend. We include the full chain because lead count alone would not explain the commercial result.
Our solar case study separates the client’s recorded baseline from future revenue and return projections, which are clearly labelled as modelled. We recommend asking any provider to distinguish results already achieved from forecasts used to plan future investment.
08 · Run a controlled test
Do not solve uncertainty with a larger opening order
We normally recommend starting with one product, a defined territory and a volume the team can handle confidently. This creates a useful first cohort without mixing too many products, locations and sales approaches together.
Allow enough time for the relevant sales outcome to develop, then review the campaign with the provider. If contact and appointment rates are healthy but sales are weak, the next conversation may be about quotation or sales process rather than simply changing the lead source. Increase volume once both teams understand what is working.
- ChooseOne product, territory and commercial model.
- PrepareA named sales owner, realistic capacity and prompt follow-up.
- RecordContact, appointment, quote, sale and reason-for-loss outcomes.
- ReviewThe first complete cohort with the provider.
- Scale or refineIncrease volume or adjust the campaign using the outcomes.
09 · Compare like with like
A practical buyer checklist for comparing providers
We would use the same questions in every provider conversation and record the answers before making a decision. The aim is not to produce an artificial score out of 100; it is to make sure price is being compared alongside the campaign, service and outcome that price includes.
| Area to compare | Question to ask | What a useful answer includes |
|---|---|---|
| Campaign source | How are these leads generated? | The channels, brands, pages and campaign control available |
| Product fit | Which enquiries can you generate for us? | Products, locations and customer criteria that match your operation |
| Commercial model | What are we paying for? | CPL, appointment or acquisition terms and what each price includes |
| Exclusivity | Will another buyer receive the same lead? | A clear exclusive or shared supply model |
| Checks and questions | What happens before delivery? | Contact checks, qualification questions and matching criteria |
| Volume | Can supply match our capacity? | Realistic volumes, locations, schedules and the ability to adjust |
| Delivery | How and when will our team receive each opportunity? | A straightforward route that works for the sales team |
| Measurement | How will we review performance? | Contact, appointment, quote, sale and revenue outcomes where available |
| Ongoing improvement | What happens when we return feedback? | A named team able to change targeting, creative, questions and filters |
Turn the shortlist into a decision
Leave the provider meeting with four concrete answers
We recommend asking shortlisted providers to respond to the same buying brief. Price is only comparable once product, territory, exclusivity and handoff are aligned. Record any exceptions beside the quote rather than relying on a reassuring conversation.
A campaign walkthrough: ask to see a representative product journey and the answers supplied to sales. For solar, distinguish someone requesting a panel-and-battery quotation from someone seeking information about a battery-only upgrade. Both can be genuine enquiries, but not every installer wants both.
A comparable commercial proposal: ask for the lead or appointment price, separate management or calling charges, funding requirements and how volume can be changed. “Appointments included” needs clarification if one offer charges for lead supply plus calling and another charges per booking.
A relevant result: ask which product, territory and sales stage a case study covers. An impressive revenue total from a national installer does not establish what a local branch will convert. Check whether the result is completed revenue, signed orders or a forecast and whether the reported cost includes the services you would buy.
A practical review process: find out who receives sales feedback, what they can change and how decisions will be recorded. For example, if replacement enquiries are useful but repair-only requests are not, the next action should identify whether to change the brief, the questions or the product targeting—not simply request “better quality”.
Use these answers to separate commercial fit from availability. A provider may have a suitable model but insufficient volume in your selected area. Start with supported requirements, leave unresolved points visible and avoid buying a broader product just to reach a headline volume.
How this relates to Adfluential
Our answers to the same buyer questions
We generate consumer enquiries through brands and campaigns we own and manage. Matching leads are supplied exclusively to one buyer, delivered in real time, and checked against the criteria agreed for the campaign.
Buyers can use direct lead delivery, add managed appointment qualification, or discuss revenue share where the sector, reporting and partnership are suitable. The Buyer Portal records delivery and downstream actions so contacted, appointed and sold outcomes can inform campaign changes.
When we speak with a new buyer, we work through the same practical questions covered in this guide: what they sell, where they operate, how much volume they can manage, which commercial model fits and which sales outcomes will help us improve performance together.
Common buyer questions
Frequently asked questions
What is a lead generation company?
A lead generation company creates or qualifies prospective customer enquiries and supplies them to a business at an agreed stage. Some providers manage campaigns, some supply individual leads and others contact those leads to arrange appointments.
How do lead generation companies work?
Providers use different models. At Adfluential, we generate enquiries through brands and campaigns we own and manage, check them against the agreed criteria and deliver matching leads exclusively and in real time.
How much should a lead generation company charge?
There is no single price that applies across every campaign. Product value, geography, exclusivity, qualification, available volume and whether you are buying a lead, appointment or acquisition all affect the commercial model. We recommend comparing cost per contact, appointment and sale as results become available.
Should I buy leads or appointments?
Buy leads when your team has the capacity and experience to contact and qualify enquiries promptly. Consider appointments when you want the provider to manage more of the initial contact and booking process. We can support both approaches depending on the sector and campaign.
What does an exclusive lead mean?
At Adfluential, an exclusive lead is supplied to one matching buyer rather than deliberately shared with several competing businesses. The customer remains free to carry out their own research and contact other companies independently.
