What Is B2B Sales? Models, Roles, Process, and How Buyers Buy in 2026

B2B sales is one business selling products or services to another business. The deals are larger than consumer sales, a group of people decides instead of one, and the process runs for weeks or months. In 6sense’s 2025 survey of nearly 4,000 business buyers, the average buying cycle was 10.1 months and buying groups averaged more than ten people.

That last point changes how B2B selling works. Six of the top eight Google results for this term, when we checked in October 2026, come from sales software vendors, and they describe the process from the seller’s side: prospect, qualify, demo, close. Current buyer research says buyers do much of their deciding before a seller is involved. This guide covers both sides: what B2B sales is, how teams are organized, the stages of a deal, and what to change now that buyers arrive with a shortlist.

How is B2B sales different from B2C sales?

	B2B sales	B2C sales
Who buys	An organization, through a group of people	One person or household
Who decides	A buying group: the user, their manager, finance, IT, legal, procurement	Usually one person
Deal size	Thousands to millions, often on an annual contract	Usually a one-time, lower price
Cycle length	Weeks to months. 6sense’s 2025 average was 10.1 months for the purchases it studied	Minutes to days
How the decision is made	Written criteria, comparisons, security and legal review	Preference, price, convenience
After the sale	Onboarding, renewal and expansion matter as much as the first deal	Repeat purchase if the customer is happy

The numbers from 6sense’s 2025 Buyer Experience Report come from purchases that are large enough to need a group decision, so a $3,000 software subscription will move faster. The direction holds for any sale that needs more than one signature.

What are the main B2B sales models?

B2B companies sell in a few distinct ways, and most mature companies combine two or three:

• Inbound sales. Buyers come to you: they request a demo, start a trial or fill in a form. The sales team qualifies and works those leads. Speed of follow-up decides how many of them you keep.
• Outbound sales. The seller starts the conversation with accounts that have not shown interest yet, through email, LinkedIn and phone. Our guide to BDRs and SDRs covers who runs inbound and who runs outbound.
• Account-based selling. Sales and marketing pick a defined list of target accounts and work each one as a market of its own, with tailored messages for each person in the buying group.
• Product-led sales. The product is the first salesperson: users sign up free, and sales steps in when usage signals a larger team purchase. Our post on product-led vs sales-led growth compares the two.
• Channel and partner sales. Resellers, agencies or technology partners sell for you or with you, usually for a share of revenue.

The other split is transactional versus complex. A transactional sale has one buyer and a short cycle, so a seller handles many at once. A complex sale has a buying group, a security review and a contract negotiation, so a seller handles few at a time and qualification matters more than volume.

Who does what on a B2B sales team?

Role	Main job	Usually measured on
SDR (sales development rep)	Follows up on inbound leads and qualifies them	Meetings booked from inbound, speed to lead
BDR (business development rep)	Starts conversations with target accounts through outbound	Meetings booked from outbound
Account executive (AE)	Runs the deal from discovery to signature	New revenue closed against quota
Sales engineer	Handles technical discovery, demos and security questions	Technical win rate, deals supported
Account manager or customer success manager	Keeps and grows the customer after the sale	Renewal rate, expansion revenue

Small companies merge these roles. A founder often does all five until the first sales hire. The Bridge Group’s 2025 report puts median on-target earnings for sales development reps at $80,000, with an average ramp of 3.0 months, which is why the first sales development hire is a real budget decision.

What are the stages of a B2B sale?

Most B2B deals move through six stages. Every CRM has stage names. The column that matters is the last one: the evidence that should exist before a deal moves on.

Stage	What happens	Move on when
1. Prospecting	Find accounts that fit and a reason to contact them now	A named person agreed to a first conversation
2. Discovery	Learn the problem, its cost and who is involved	You can state the problem and its cost in the buyer’s words
3. Qualification	Test whether the deal can close	Budget owner, decision process and timeline are known
4. Solution and demo	Show how the product solves this buyer’s problem	The buyer agrees it meets their criteria
5. Proposal and negotiation	Price, terms, security and legal review	Verbal yes from the person who signs
6. Close and handoff	Contract signed, handed to onboarding	Signed contract and a kickoff date

For complex deals, qualification deserves its own framework. MEDDIC is the most common one: it checks for metrics, the economic buyer, decision criteria, the decision process, the pain and an internal champion. Our guide to the B2B SaaS sales funnel covers how these stages connect to marketing’s side of the funnel.

How do B2B buyers buy today?

This is where most B2B sales guides are out of date. The 6sense 2025 Buyer Experience Report, based on nearly 4,000 buyers in North America, EMEA and APAC, found:

• Buyers contact sellers late. The first contact with a seller came 61% of the way through the buying journey, earlier than the 69% in 2024 but still well past halfway.
• The shortlist is set early. Buyers chose the winner from the vendors on their first-day shortlist 95% of the time, up from 85% the year before.
• AI is part of the research. 94% of buyers reported using large language models during the purchase.

Two practical consequences follow. First, a large share of B2B selling now happens before the first call, through what buyers find when they search, what AI assistants say about you and what peers recommend. Content, reviews and visibility in AI answers belong to the sales process as much as to marketing. Second, outbound still works, but its job has shifted toward getting onto the shortlist of accounts that are about to start buying, which is why timing signals like a new executive or a funding round matter more than volume.

What a B2B deal looks like: an illustrative example

Illustrative, not a benchmark. The company is fictional.

Harbor Freightworks, a 250-person logistics company, needs to replace its spreadsheet-based fleet scheduling. The operations director starts researching in January, asks an AI assistant for options and reads two comparison articles. By March she has a shortlist of three vendors, ranked.

She requests a demo from her first choice. The account executive runs discovery and learns the problem costs the dispatch team about two days a week. IT joins the second call for a security review. Finance asks for a three-year cost comparison. Legal redlines the contract in May. The deal signs in June, six people later.

The seller’s work mattered at every stage after March. But the deal was mostly won in January and February, when the operations director built her shortlist from what she could find without talking to anyone.

What does it take to sell B2B well?

• Know your best customer precisely. Industry, size, the trigger that makes them buy now, and who signs. Everything else depends on it.
• Be findable before the first call. Clear pricing information, comparison pages, reviews and content that answers buyers’ real questions.
• Qualify hard in complex deals. A full pipeline of deals with no economic buyer is a forecast miss waiting to happen.
• Sell to the group. Map who is involved and give each of them a reason to say yes.
• Follow up fast and in writing. Recap every call the same day so the buying group can pass your case around internally.

Salesforce’s research found that reps spend 70% of their time on non-selling tasks. Much of that is research, follow-up and CRM updates, exactly the work that is now easiest to hand to software with a person checking the result. Growigami’s ABM and outbound service does the account research and writes a message for each contact every week, and replies reach your sellers the same day.
