A buying center describes all people involved in a B2B purchasing decision. In web projects, decisions are rarely made by individuals — marketing, IT, management and procurement are all involved. Your website must address all these roles. Since 2012, arocom has understood the typical buying center structures in website decisions and designs content that meets each decision-maker where they stand.

Buying Center: Who Decides on Your Web Project?

Last updated: March 2026 · Reading time: 4 minutes

In B2B, nobody buys alone. The marketing director wants a modern website. The IT director asks about security and maintainability. The executive board wants to see ROI. Procurement compares quotes.

Your website must serve all these perspectives.

The Five Roles in the Buying Center

Initiator: Recognizes the need and starts the process. Often the marketing or project manager.

Influencer: Provides expert assessment. The IT department evaluates technical feasibility.

Decision-maker: Has budget authority. Often the executive management.

Procurement: Negotiates terms and compares offers.

User: Works daily with the result. Editors, content managers, marketing team.

Optimizing Your Website for the Buying Center

Each role needs different information. The initiator needs inspiration and references. The influencer needs technical depth. The decision-maker needs business cases and ROI figures.

arocom structures websites so that every role finds their entry point: references for the initiator, knowledge articles for the influencer, the Future Check as a concrete offer for the decision-maker.

Your next step

Want to optimize your website for B2B decision-makers? The Drupal Future Check analyzes whether your website addresses all relevant target audiences.

How large is a typical buying center for web projects?

Three to seven people. More in larger organizations. The mistake many agencies make: they only talk to the initiator and forget the other decision-makers.

How do we identify our own buying center?

Ask yourselves: who must approve before the contract is signed? Who can block the project? Who has budget responsibility? The answers define your buying center.
