Outsourced SDR vs In-House: Which Is Right for Your Business?

One of the biggest decisions B2B companies face is whether to hire in-house SDRs or outsource appointment setting. Both approaches have merits — but the right choice depends on your stage, budget, and growth targets.

The True Cost of In-House SDRs

Hiring an SDR in the UK costs £35,000-55,000 in base salary, plus £10,000-20,000 in OTE commission, plus employer NI and pension contributions, plus tools (LinkedIn Sales Navigator, CRM, email platform — £500-1,500/month), plus management overhead. Total cost: £60,000-90,000 per SDR per year.

The Cost of Outsourced SDR Services

Outsourced appointment setting typically costs £1,500-5,000 per month — a fraction of in-house costs. You get an entire team (setter, strategist, tech support) without recruitment, training, or management burden.

Speed to Results

In-house: 3-6 months to hire, onboard, and ramp an SDR. Outsourced: 7-14 days from signing to first outreach. For companies that need meetings now, outsourcing wins decisively.

Scalability

Scaling in-house requires repeating the entire hiring process. Outsourced teams can scale volume within days by deploying additional profiles and setters.

Quality and Expertise

The best outsourced providers have refined their processes across hundreds of campaigns. They know what messaging works, which targeting parameters convert, and how to handle objections — expertise that takes years to build internally.

When In-House Makes Sense

In-house SDRs are better when: you need deep product knowledge in conversations, you're in a highly technical niche, you have strong sales management in place, and you're planning for 12+ month commitments.

When Outsourcing Makes Sense

Outsource when: you need results quickly, you don't have sales management bandwidth, you want to test new markets before committing, you need predictable costs, or you want to supplement your existing team's pipeline.

The Hybrid Approach

Many successful companies use both — outsourced setters for top-of-funnel prospecting and in-house SDRs for warmer, more complex conversations. This hybrid model maximises pipeline while maintaining quality.
