What Is Inside Sales? Roles, KPIs, How It Differs from Telemarketing, and How to Start
Inside sales is the work of establishing contact, qualifying needs, nurturing interest, and generating sales conversations through remote channels such as phone, email, social media, and video meetings. It covers more than telemarketing: the team manages who to contact, how a prospect advances, and what context is handed to the next owner.
Key takeaways
- Inside sales uses multiple remote channels to move prospects toward a qualified sales conversation; telemarketing is a narrower phone-based activity.
- SDRs usually work known or inbound leads, while BDRs create new contact with selected accounts. Define the actual scope instead of relying on the title.
- Track activity, contact, qualified conversation, next-step agreement, and held meetings with a fixed denominator and observation window.
- Kachilu supports the upstream BDR workflow on LinkedIn, while your sales team handles conversations, meetings, proposals, and negotiation.

Inside sales moves prospects toward revenue without relying on in-person visits
Inside sales does not simply mean making calls from an office. It is a sales responsibility that combines phone, email, social media, and video meetings to advance relationships without requiring an in-person visit. Some teams stop at qualified meeting creation; others run remote discovery, proposals, and closing as well.
Telemarketing can be one inside-sales channel. The practical difference is the goal and the managed scope. An inside-sales process does not stop at call volume or booked appointments: it qualifies context, creates a reason for the next conversation, and records what the next owner needs.
| Dimension | Inside sales | Telemarketing | Field sales |
|---|---|---|---|
| Primary channels | Phone, email, social, and video | Phone | In-person and online meetings |
| Primary goal | Build context, qualify, nurture, and create meetings | Book appointments | Discover, propose, negotiate, and close |
| Managed scope | Multiple stages from targeting to handoff | Calls through appointment booking | Meetings through contract decision |
| Information retained | Touches, conversations, needs, and next actions | Call outcomes and dates | Discovery, proposals, quotes, and win/loss reasons |

SDR, BDR, and full-cycle models start with different prospects
The design changes according to where prospects come from and where ownership ends. SDR and BDR labels vary between companies, so document the audience, entry condition, exit condition, and handoff before naming the team.
| Model | Starting audience | Primary responsibility | Example exit condition |
|---|---|---|---|
| SDR / inbound | Leads with an existing touch, such as a demo request or event registration | Respond quickly, understand context, and nurture | Meets the qualified-meeting criteria and is handed to sales |
| BDR / outbound | Selected accounts and roles with no prior relationship | Create a relevant reason to connect and open a conversation | Interest is confirmed and a next conversation is accepted |
| Full-cycle | Inbound or outbound prospects | Own contact, discovery, proposal, and close | Record a win, loss, or future follow-up decision |

The role of inside sales is to improve handoff quality, not just meeting volume
If the job is defined only by calls or booked meetings, the team can produce off-target appointments with little context. Design the path from first contact to handoff so the next owner does not need to repeat the first conversation.
- 1.Confirm that an account and contact fit the target criteria and remove exclusions.
- 2.Choose an appropriate channel and a relevant reason to contact the prospect.
- 3.Learn the problem, priority, timing, stakeholders, and useful next information from the conversation.
- 4.For prospects who are not ready, agree on useful information and a future follow-up point.
- 5.At handoff, share why the prospect was targeted, prior touches, verified needs, and the accepted next action.
Inside-sales KPIs should separate activity, contact, conversation, and meetings
KPIs should reveal where prospects leave the process, not simply make the team busier. Show counts and rates together, and fix the denominator, observation window, and unique-prospect rule before comparing performance.
| Stage | Example KPI | Example calculation | What it diagnoses |
|---|---|---|---|
| Target | Eligible prospects and fit rate | Eligible prospects ÷ prospects reviewed | Whether the market and selection criteria fit |
| Contact | Contact or connection rate | Prospects contacted ÷ outreach starts | Whether the channel and contact reason reach people |
| Response | Reply or qualified-conversation rate | Qualified conversations ÷ contacted prospects | Whether the message creates a useful conversation |
| Agreement | Next-step acceptance rate | Accepted next steps ÷ outreach starts | Whether targeting, contact, and conversation work together |
| Meeting | Held or qualified-meeting rate | Held qualified meetings ÷ booked meetings | Whether qualification and handoff quality align |
| Business outcome | Opportunity and revenue contribution | Tie opportunities or revenue to the same cohort | Whether upstream work contributes to pipeline |
SDR teams often emphasize speed-to-lead and conversion from known demand, while BDR teams often emphasize fit, contact, qualified conversation, and next-step acceptance. Both should eventually trace the same cohort into meetings, opportunities, and revenue. Do not import an industry benchmark when its scope and denominator differ from yours.

Start inside sales with seven small, testable decisions
Before hiring a larger team or adding tools, decide who the team contacts, why, and when ownership passes to someone else. Start with one audience and one primary channel so a weak stage is easier to find.
- 1.Choose one objective: create new meetings, respond to inbound demand faster, or reactivate dormant leads.
- 2.Choose an SDR or BDR motion: respond to existing demand or create contact with selected accounts.
- 3.Define target and exclusion criteria using industry, size, role, problem, region, and current context.
- 4.Define stages and handoff rules so contact, response, qualified conversation, next step, and meeting mean the same thing.
- 5.Choose one primary channel and prepare messages that make the contact reason clear.
- 6.Choose the system of record and owners for targeting rationale, touches, conversations, timing, and handoff.
- 7.Run a small cohort and review it weekly; change one variable at the first stage that loses prospects.
Kachilu supports a LinkedIn BDR motion from prospect selection
A BDR motion repeatedly requires the team to find people with no existing relationship, verify fit, and create a relevant reason to start a conversation. Kachilu uses service information to suggest target criteria and draft message templates. Users review and edit the audience, copy, volume, days, and times before execution.
The workflow covers LinkedIn prospect search, relevant post engagement, personalized connection requests, direct messages after acceptance, follow-ups, reply checks, and a CTA when configured conditions are met. Users can see each prospect's stage and task state and pause, resume, or skip work. The sales team takes over one-to-one conversations, meetings, proposals, and negotiation after interest is confirmed.

Can one person start inside sales?
Yes. Start with one audience, one channel, and one objective, then test a small prospect cohort from contact through handoff. Reserve time for replies and meetings before increasing volume.
