What is B2B sales?

Many pages on B2B sales still quote figures from years ago. This one uses current research: Gartner's 2025 and 2026 surveys on buying groups and rep-free buying, and McKinsey's 2024 B2B Pulse on channels. It also covers something the general pages skip, the deal size below which outbound selling to businesses does not pay.

What is B2B sales?

B2B sales covers every sale where the customer is a business: software to a sales team, components to a manufacturer, consulting to a bank. The seller's job is to show that the purchase solves a business problem at a cost the business accepts, and to get several people inside the customer to agree on that.

The work splits into stages that this glossary covers one by one: deciding whom to sell to, starting conversations, qualifying interest, running discovery and moving deals through a pipeline to a close.

Because the buyer is a business, the argument is about outcomes the business can measure: revenue gained, cost removed, risk reduced, time saved. Personal preference still plays a part, but a B2B purchase that cannot be justified in those terms rarely survives the review by the rest of the buying group.

How is B2B buying different from B2C?

B2B buying involves more people, more money per decision and a longer process. A consumer can buy on impulse; a company usually needs a business case, a budget owner and sign-off from people who will never use the product.

B2B figures from the cited surveys. The B2C column is a qualitative contrast, not survey data.

The figures on this page come from four surveys. Gartner's 2025 sales survey (632 respondents) covers buying-group size and conflict. Its 2026 survey (646 respondents) covers rep-free buying and AI use. McKinsey's B2B Pulse 2024 covers channels. LinkedIn's State of Sales 2022 covers deals lost when a stakeholder leaves.

How many people decide, and how do they buy today?

Between 5 and 16 people, drawn from up to four functions, according to Gartner's 2025 survey of 632 B2B buyers. Getting them to agree is the hard part: 74 % of the buyer teams in that survey showed unhealthy conflict during the decision. Selling to one enthusiastic contact is not enough; the seller has to help that person win the internal argument.

Buyers also want to do more on their own. Gartner's survey of 646 buyers, released in March 2026, found that 67 % prefer a rep-free buying experience, and 45 % had used AI during a recent purchase. McKinsey's 2024 B2B Pulse, with around 4,000 respondents, found buyers using about ten channels in a typical journey and describes a rule of thirds: roughly equal use of in-person, remote and self-serve channels. For sellers, that means being useful on every channel, and reaching the buying group before it has decided without them.

What deal size makes B2B outbound worth it?

Outbound needs a deal large enough to cover the cost of reaching people: domains, mailboxes, data and tools. That cost does not shrink for a cheap product. Leadspicker's guidance is that cold outreach is minimum viable above €1,000 per deal, and that the sweet spot is around €5,000 a year. Below that floor, inbound, self-serve or partner channels usually work better. The ideal customer profile page covers the full deal-size check.

The floor applies to the deal, not to the company. A large enterprise buying a cheap add-on is still a cheap deal. Check the expected first-year value of the contract, not the size of the logo, before deciding whether outbound is the right channel for a segment.

Frequently asked questions

What is the difference between B2B and B2C sales?

B2B sales sells to companies, B2C to individual consumers. B2B deals involve buying groups of 5 to 16 people, larger amounts and longer processes; B2C purchases are usually made by one person, often quickly.

How long is a B2B sales cycle?

It ranges from days for a small software subscription to many months for a complex purchase. The more people in the buying group and the larger the deal, the longer it tends to take.

Do B2B buyers still want to talk to salespeople?

Less than before. Gartner's 2026 survey found 67 % of B2B buyers prefer a rep-free experience. Sellers still matter, but mainly where they add something buyers cannot get on their own.
