What is B2B sales? Definition, sales cycle and roles

B2B sales definition: what does B2B sales mean?

Salesforce answers "What is B2B sales?" in one line: one business sells goods or services to another. B2B stands for business-to-business, so the buyer is a company, not a person shopping for themselves.

Anything sold between two businesses counts, from wood for a cabinet maker to software for a manufacturer.

B2B vs B2C sales: what is the difference?

The difference is who buys and how they decide. In B2C sales, a business sells to a consumer, who can decide alone and fast. In B2B sales, a group of people at a company decides together.

B2B deals are also larger and built on long-term relationships. A deal can run into the millions of dollars, and buyers keep a product longer, because switching costs time and money.

Why do B2B deals take so long?

Because more people have to say yes. 6sense finds that typical B2B purchases, averaging about $250,000, involve 10 or more people and take close to a year. Its 2025 survey of nearly 4,000 buyers put the average buying cycle at 10.1 months.

Unless you sell to a small business, expect IT, legal, procurement and senior leaders to join in, each with their own needs.

Buyers also decide a lot before they call you. In 2025, they first contacted a seller 61% of the way through their journey, 6sense found. The vendor they favored by then wins about four deals in five.

What are the stages of the B2B sales cycle?

Salesforce lists six core stages: prospecting, qualification, needs assessment, proposal and quote, negotiation and close. HubSpot's seven steps end with following up after the sale and asking for referrals.

• Prospecting: find companies and people who could buy, through ads or outreach based on research.
• Qualification: check that a lead fits your product before you spend more time on it.
• Needs assessment: learn the buyer's needs, goals and challenges, often on a discovery call.
• Proposal and quote: present a solution made for this buyer, with its price.
• Negotiation: work out the terms and answer pushback on price or timing.
• Close: sign the contract and process the sale.

Who does what in B2B sales? SDR, AE and CSM

HubSpot describes three roles that pass a deal along. Sales development reps (SDRs) hand warm prospects to account executives (AEs), who work with customer success managers (CSMs) once the deal is signed.

Where teams have SDRs, The Bridge Group's 2025 survey of 351 B2B companies found about one SDR for every 2.4 AEs. On a small team, one person may do all three jobs.

• SDR: finds and qualifies leads, then books meetings for an AE.
• AE: runs the presentations, the negotiation and the close, and is the buyer's main contact.
• CSM: guides the customer after the sale, drives product adoption, manages renewals and finds chances to sell more.

Inbound vs outbound B2B sales: which should you use?

Usually both, says Salesforce. The difference is who starts the conversation. With inbound, buyers come to you through search, ads, content or word of mouth. With outbound, a rep reaches out first by email, a cold call or LinkedIn.

Salesforce's rule of thumb: a well-known brand gets steady inbound, while a new company with an unfamiliar product needs more outbound. Outbound also suits complex, high-priced products with a small pool of buyers.

Either way, aim to be known before buyers build their shortlist. In 2025, buyers made the first contact 79% of the time, 6sense found. Most first spoke with the vendor that went on to win.

How does a B2B sales team work a deal in practice?

In practice, a team turns a list of companies into meetings, then deals, then customers. Here is one deal in OXYGEN, where AI does the research and drafting within the approvals and spending limits you set. Say you sell inventory software to operations leaders at US manufacturers with 50 to 500 employees.

• Prospect: Company Search filters companies by industry, size and location. The preview is free; saving the list is priced first and needs your approval.
• Qualify: a Classify column scores each company against your ideal customer profile (ICP) and gives a reason.
• Find the buying group: the "Find decision makers at companies" source lists people at each account by job level and function. A free sample comes first.
• Reach out: a sequence gives each lead a planned series of emails, LinkedIn messages and call tasks. Adding leads sends nothing; only starting it does.
• Work the replies: replies land in one inbox, Unibox, with an AI label such as Interested. A reply stops that lead on every channel.
• Run the deal: add it to the Pipeline board in OXYGEN's CRM, its database of companies, people and deals. Drag it from stage to stage.
• Hand off: when the deal is won, file a task on it, assign it to your customer success manager and set a deadline.

What mistakes do B2B sales teams make?

Most come from treating a group decision like a quick sale to one person.

• Talking to the wrong people: time spent on managers who cannot make the decision is time lost.
• Rushing the buying group: pushing IT, legal and procurement to move faster than they are comfortable with.
• Sales and marketing working apart: Salesforce names poor coordination between the two as a common challenge.
• Messy CRM data: HubSpot says duplicate records, missing fields and stale lead statuses quietly break sales work.
• Badmouthing rivals: build relationships instead of pushing a hard sell.

What OXYGEN does not do here

• It does not hold your sales meetings: discovery calls, demos and negotiation stay with your team.
• No contact database of its own: lead data comes from data providers, on credits.
• Calls are in beta: a call task queues the lead for a person to dial in the web softphone.
• No Salesforce sync; HubSpot syncs both ways, Attio one way, and Pipedrive imports.
• The Pipeline board starts with four stages; add your own to match a longer sales cycle.
