Quick answer
They answer different questions, so you don't choose one over the other. Outbound sales is about who starts the conversation: your team reaches out first instead of waiting for inbound leads. Inside sales is about where the rep sells: remotely, by email, phone, LinkedIn and video, instead of in person (outside or field sales). An inside sales rep can run outbound, inbound or both. For most early-stage B2B companies the right start is inside sales running outbound, with the founder still closing and in-person meetings saved for the deals where buyers want them.
Two axes, not two options
I'm a GTM consultant working on cold email and LinkedIn outbound for B2B teams, and this mix-up shows up all the time when founders write their first sales job post. "Should we do outbound or inside sales?" mixes two separate questions:
- Outbound vs inbound: who starts the conversation, you or the buyer.
- Inside vs outside (field): where the selling happens, from a desk or in person.
Put them on a grid and every sales role fits in one of four boxes:
| Outbound: you reach out first | Inbound: the buyer comes to you | |
|---|---|---|
| Inside: remote | An SDR sending cold email and LinkedIn messages to a target list and booking video calls | A rep answering demo requests from the website and booking calls |
| Outside: in person | A field rep working a list of named accounts in a region and visiting them | A field rep meeting buyers who asked for a visit or stopped at the trade show stand |
Early-stage B2B teams usually start in the top row, and most end up working both columns.
What outbound sales means
Outbound means your team picks who to contact and reaches out first: cold email, LinkedIn, phone, meetings booked ahead of an event. The person hasn't asked to talk to you. Inbound means they made the first move: a demo request, a form, a reply to your content, a referral.
Outbound is the motion you control. You choose the market, the accounts and the timing. It's also the smaller share of how B2B conversations start. In 6sense's 2025 Buyer Experience Report, a survey of nearly 4,000 B2B buyers, buyers started 79% of engagements with sellers, and the vendor they contacted first won about four deals in five. So outbound pays off when it reaches people early or right after something changes for them. The best lead is the one who just did something.
The job titles don't help. SDR and BDR mean outbound at one company and inbound at the next, so read the responsibilities, not the acronym. I break that down in SDR vs BDR: which to hire first. For the bigger question of which motion an early-stage company should start with, see inbound vs outbound for early-stage B2B.
What inside sales means
Inside sales is selling remotely: email, phone, LinkedIn and video calls, from the office or from home. Its opposite is outside or field sales, where reps meet buyers in person: visits, site tours, trade shows, dinners.
Buyers accept remote for a big part of the journey, but not all of it. McKinsey's 2024 B2B Pulse Survey (nearly 4,000 decision makers in 13 countries, published September 2024) found what it calls the rule of thirds:
- At any stage of buying, about a third of customers want in-person contact, a third want remote and a third want digital self-serve.
- 41% prefer in-person channels when dealing with a new supplier, and 40% when buying something for the first time.
- Buyers use 10 channels on average across their journey.
So a fully remote sales team is normal, and inside sales can carry most of the cycle. But if your deals are large first-time purchases from a supplier the buyer doesn't know yet, plan for some meetings in person, even if nobody on the team has "field" in their title.
Where the two terms get mixed up
- "Inside sales representative" on an outbound job. The title says where the person works. Only the job description says who starts the conversations.
- "Inside sales" meaning the inbound team. Some companies use it for the people who answer demo requests, which makes "outbound vs inside sales" sound like a real choice.
- "Outbound" meaning any prospecting. A field rep who opens doors in their territory is doing outbound too, just in person.
None of this matters until you hire on a title and get the wrong job done. A rep hired as "inside sales" who expected to answer warm leads often struggles on a cold list, and the other way round.
Which combination fits your company
| Your situation | Who starts | Where | First setup |
|---|---|---|---|
| Little inbound, and you can name the companies and titles that buy | Outbound | Inside | An outbound function booking calls, the founder closing |
| Inbound leads arrive faster than anyone answers them | Inbound | Inside | Someone who replies within hours and qualifies, the founder or an AE closing |
| A small list of large accounts buying from you for the first time | Outbound | Inside to open, in person for key meetings | A senior seller who prospects remotely and travels when a deal needs it |
| Both lead sources, past the first hires | Both | Mostly inside | Separate owners for outbound and inbound, with a rule for who owns an account when a lead crosses over |
Start with outbound, inside, if
- you can list the companies and job titles that buy, and inbound is thin;
- deals can be won over video calls;
- you need conversations this quarter, not when your content starts ranking.
Start with inbound, inside, if
- leads already come in and wait days for an answer;
- buyers already search for your category by name.
Add in-person selling when
- one deal is worth many times the cost of the trip;
- buyers are choosing a new supplier or buying something for the first time;
- your prospects tell you, more than once, that they want to meet before they sign.
How to set up your first team on both axes
- Look at your current deals. For each closed deal and open opportunity, note who started the conversation and whether anyone met in person. That's the mix you actually run today.
- Decide the motion before the title. Write down who starts the conversations and where the person meets buyers. Then pick the title. If you can't write it, you're not ready to hire.
- Don't give one junior person cold outbound and fast inbound replies with no rule. Inbound leads are urgent, so they win every day and the outbound list sits untouched. Give inbound to someone else or set fixed time blocks for each.
- Hand over one job and keep closing yourself. Ramp is long: The Bridge Group's 2025 SDR report (351 B2B companies) puts average SDR ramp at 3.0 months and the average ratio at 1 SDR to 2.4 AEs. Its 2026 AE report (158 companies) puts AE ramp at 6.2 months. Which job to hand over first, and whether to hire, use an agency or go fractional, is in your first GTM hire.
- Build the outbound system before the rep starts. A list, the copy and warmed-up domains have to exist on day one, or the rep spends the first months building them. More in done-for-you outbound vs hiring an SDR.
When I set up the outbound function inside a team, email and LinkedIn run as one sequence and new domains get 3 to 4 weeks of warmup before full volume. All of it is inside sales by this definition.
Two sentences before you post the job. Who starts the conversations this person handles? Where do they meet buyers? If the job description can't answer both, the role isn't ready.
Key takeaways
- Outbound vs inbound is about who starts the conversation. Inside vs outside is about where the selling happens. They combine; you don't pick one.
- An inside sales rep can run outbound, inbound or both. Read the job description, not the title.
- Buyers started 79% of engagements in 6sense's 2025 survey, so outbound works best when it reaches people early or right after a change.
- McKinsey's rule of thirds: a third of buyers want in-person contact at any stage, and 41% prefer it with a new supplier. Remote can carry most of the cycle, not all of it.
- For most early-stage B2B companies: outbound, inside, founder closing, in-person meetings only where a deal needs them.
FAQ
Is inside sales the same as outbound sales?
No. Inside sales describes where you sell: remotely, instead of in person. Outbound describes who starts the conversation: your team, instead of the buyer. An inside sales rep can run outbound, inbound or both.
What is the difference between inside sales and outside sales?
Inside sales reps sell remotely by email, phone, LinkedIn and video. Outside or field sales reps meet buyers in person. Many teams mix them, selling remotely for most of the cycle and meeting in person for large first-time deals.
Is inside sales inbound or outbound?
Either. "Inside" only says the rep works remotely. An inside rep booking meetings from a cold list is doing outbound, and one answering demo requests is doing inbound.
Is an SDR an inside sales role?
Usually, since SDRs and BDRs mostly work by email, phone and LinkedIn. Whether the role is outbound or inbound depends on the company, so read the responsibilities rather than the title.
Should a startup start with inside sales or field sales?
Most B2B startups start with inside sales: one person can hold far more conversations a week from a desk than on the road, and buyers accept remote for much of the journey. Add in-person meetings for large first-time deals, where McKinsey found 41% of buyers prefer to meet a new supplier in person.
