The short answer

The short version.

Part 2 of the lead generation companies series. You know the four types; now compare vendors inside your type.
Ask what share of records carry a mobile or direct dial, when numbers were last checked, and what happens when a record is wrong.
Ask for a sample you can dial before paying, and the answer to who owns the data if you leave.
A vendor that answers all nine crisply is rare, and that is the point of asking.

Part 1 of this series separated the four types of lead generation company. Part 2 assumes you know which type you want and need to choose between vendors. These nine questions work for any of the four, and the quality of the answers matters more than the answers themselves.

Questions about the product

What exactly do I receive, what share of records carry a mobile number or direct dial, and on what date was each contact detail last checked?

These three expose what you are actually buying. A real answer to the first names the fields on a record. A real answer to the second is a percentage, and for a calling list you want the large majority to be mobile or direct dial, not switchboards. A real answer to the third is a date or a build process, not the word updated.

Vague answers here are not a communication problem. They are the product telling you what it is.

Questions about the economics

What is the full monthly cost at my volume, what happens when a record is wrong, and what does a booked meeting cost me when I add my team's time?

Headline prices in this market hide in credits, seats, minimums and setup fees, so ask for the all-in monthly number at your volume in writing. Then the replacement question: wrong numbers happen to everyone, and the honest vendors replace them free within fair-use limits. The rest charge you twice.

Finally, run the meeting maths yourself. Add your caller's hourly cost to the data or meeting price and divide by realistic connect and meeting rates. Two vendors at very different record prices often land within cents of each other per meeting, and the cheaper-looking one is not always the cheaper one.

Question	A good answer sounds like
What exactly do I receive per record?	A named field list, unprompted
What share carry a mobile or direct dial?	A percentage above 80 percent
When was each number last checked?	At build time, days before delivery
Full monthly cost at my volume?	One number, in writing
What happens when a record is wrong?	Free replacement within fair use
Can I dial a sample first?	Yes, here are five now
Can I change volume monthly?	Yes, self-serve
Who owns the data if I leave?	You do
What do your buyers complain about most?	A specific, honest answer

The nine questions, with what a good answer sounds like

Questions about the relationship

Can I dial a sample before paying, can I change volume month to month, and who owns the data if I cancel?

The sample question is the strongest one on the list. A vendor confident in its data will hand you records to dial today, because twenty of your own calls outsell any pitch. Refusing a dialable sample tells you the file cannot survive one.

Flexibility and ownership matter at the end of the relationship, not the start. Monthly volume changes stop you paying for records your team cannot work. And owning the data outright means a cancelled subscription leaves you with every contact you already paid for.

The bonus question

Ask what their customers complain about most. Honest vendors name something specific; everyone else tells you they rarely get complaints.

Every product in this market has a weakness: coverage in a niche, speed at high volume, a rigid profile builder. A vendor who names theirs and explains what they do about it is one you can work with. A vendor with no complaints has not been paying attention, or does not plan to tell you.

Key takeaways

Ask for a dialable sample before anything else. It replaces most of the other diligence.
Get the all-in monthly cost at your volume in writing.
Free replacement of wrong records is the line between honest and expensive data.

Frequently asked questions

What is the single best question to ask a lead generation company?

Can I dial a sample before I pay? Twenty of your own calls to real records tells you more than every other answer combined.

How do I know if a vendor's data is fresh?

Ask when each number was last checked. A build process that checks at delivery time is fresh. An answer about regular updates to a master file usually means a warehouse.

Should a lead generation company replace bad records?

Yes. Wrong numbers are a fact of the market, and honest vendors replace them free within fair-use limits. If replacements cost extra, the headline price is not the real price.

Does LeadNumbers offer a sample?

Yes. Five sample prospects matched to your profile are free at /sample, built to the same standard as a paid batch.
