Types of Decision Makers in B2B and How to Reach Each

A decision maker in B2B is anyone whose yes or no changes whether a purchase happens. In most company purchases that is a group. Researchers call it the buying center or the decision-making unit (DMU).

The classic model, from Webster and Wind in 1972, names five types of decision makers:

1. Users
2. Influencers
3. Buyers
4. Deciders
5. Gatekeepers

(EBSCO Research Starters)

Sales teams now use other labels for the same people, and the role table further down maps them. One person can hold several of these roles at the same time.

What does each buying center role do?

• Users work with the product or service once it is bought.
• Influencers shape the requirements and the shortlist.
• Buyers are the people responsible for the contract in this model.
• Deciders hold final approval.
• Gatekeepers control the flow of information and access. EBSCO's summary notes they can prevent or discourage a purchase.

The same summary notes that DMU makeup differs by organization and by buying situation. Company size is the easiest example.

In a 20-person firm the founder may be decider, buyer and user in one chair. In a 2,000-person firm those can be five different people in three departments who have never met. I never assume one map fits two markets, because no two businesses buy the same way.

How many people actually take part in the decision?

Read the conflict row next to the size rows. This is where a "find the one C-suite signer" approach fails: the signer is real, but a group has to agree first, and people outside the company can overrule them. For committee-size detail, see how big a B2B buying committee really is.

How do the classic roles map to economic buyer, champion and blocker?

The modern labels come from sales practice, not research. They are useful because each one tells you what to say.

Forrester's 2026 release puts procurement staff in a deciding role in 53% of business buying cycles, involved from the start.

The blocker is a behavior, so no job title marks it. An assistant who never forwards your note is a blocker. So is a technical lead who prefers the incumbent vendor. You cannot filter a list for blockers. You find them in conversation.

How do you find the real decision maker before you send anything?

Start from your own closed deals. A lead tool's title suggestions are only a guess.

On every new list I go back through the client's past projects and ask one question: who actually made the buying call? Then I search with the titles that niche really uses, never a plain "manager".

The decision rule:

1. Open your last 10 closed deals.
2. For each one, write down who signed, who championed you inside, and who joined the calls.
3. Count which titles repeat in each column.
4. Target the repeating signer and champion titles first. The others join later in the sequence.
5. If no title repeats, your deals are too varied to map yet. Narrow the segment before you build a list.

A quick example: when a company buys software or IT services, the signer is often a CTO, a head of IT or an IT director, depending on company size, rather than a generic IT manager.

Run this checklist before a list goes out:

• Remove Assistant, Manager and Associate when they stand alone as titles. I cut them from every list I build.
• Check every title against your past-deal columns. If it matches none, it needs a reason to stay.
• Confirm the role exists at the target company size. Small firms often have no procurement function at all.
• Tag each contact with the role you expect them to play, so the sequence knows what to say.

To decide whether company fit or person fit should filter that list first, read ICP or buyer persona.

How should outbound reach each role?

Each role needs a different first contact. LinkedIn comes before email for me every time, so the email arrives from someone they already recognize. One or two messages never start a conversation, so I plan 5 to 6 touch points per person at minimum, across more than one channel where possible. The numbers behind that are in the multichannel outreach statistics that hold up.

Whether the economic buyer should be the CEO or a department head depends on deal size. That trade-off is in should you email the CEO or the department head. For how many of these people to put in one sequence, see how many people to contact at one company.

Here is a made-up first message to a champion at a mid-size logistics company, from a software development firm:

Subject: route planning rebuild

Hi Marta, I saw your team is hiring two dispatch planners while the planning tool stays the same. We rebuild route planning software for logistics firms your size, usually without replacing the systems around it. I put together a two-page summary of how a similar rebuild was scoped, written so your CTO can read it in 5 minutes. Would a 20-minute call next week be useful, or should I send the summary first?

Why do committee members check you before they reply?

Expect everyone you contact to look you up. Nobody buys from an email. They audit you first, and only then do they reply. The CTO opens your LinkedIn profile to see if you understand the problem. The CFO checks your website for proof you have done this before.

The sale is happening online, before the call, not on it. Gartner's 2025 survey of 632 B2B buyers found most buyers prefer to carry out independent research through digital channels. Your profile and your site get read before you do.

In a committee that check happens several times: the champion forwards your note, and the CTO and the CFO each look you up again. A strong profile can carry a weak message. A ghost profile sinks even a perfect one.

I have seen it in the numbers. Same message, two companies. One got 2% replies, the other 7.5%. The only difference was the foundations. So every LinkedIn profile in your sales process needs work, the founder's included.

The same Gartner survey puts a number on writing for the group. Tailoring for buying group relevance improves consensus by 20%, while relevance aimed only at the individual has a 59% negative impact on consensus. In practice, every message to one person should hand them something useful for the others: a short summary, a cost line for finance, or a risk note for the technical buyer.

Where do decision-making styles fit in?

Decision-making styles, the labels behind most four-type lists, describe how a person decides: some decide fast, some want data first, some wait for consensus. A role tells you what someone controls in the deal. A style only tells you how they behave while deciding.

You cannot filter a list by style. Target roles. Let whoever runs the call read the style.

What does this mean for who books and who closes?

We book meetings by cold email and LinkedIn, while the client's sales team takes those meetings and closes the deals. Booking meetings and closing deals are separate jobs that need different skills. If their team cannot get the economic buyer into the conversation, more booked calls will not fix it. A low closing ratio only gets worse as the calendar fills.

The role map connects the two. A booked call with the champion is a start; the closer still has to bring in the economic buyer, answer the technical buyer and involve procurement early.

Hand your sales team the role tags from the list, so the first call starts with one question: who else needs to be in the room? Your closers also need to know how this prospect makes a decision and where selling stops and closing starts, so those tags double as a checklist for preparing each call. Map the roles first. Then write the messages.

Mapping the people behind one target account and unsure who to write to first? Book a call and bring the company name. I will give you my order.
