In-House SDR or External Sales Team: When Each One Fits

An in-house SDR fits if you already have a defined sales process, time to train them and a steady volume of accounts. An external sales team fits if you need to open conversations with decision-makers without building a team or training one. The difference is who takes on the launch, the management and the risk that it doesn't work.

The question you are really asking

When someone hesitates between hiring an SDR and outsourcing, they are almost never hesitating over the money. They are hesitating over something else: who is going to make sure this gets off the ground. A new SDR needs someone to explain the product, the market and how the buyer talks. That someone is you, or your sales director, and those hours are scarce.

What each option does

• In-house SDR: one of your own people who prospects and books meetings for your team.
• External sales team: a team that detects the buying moment and opens the conversation with decision-makers, with its own process.
• Contact list provider: hands you names and emails, not meetings.
• Distributor or commission agent: sells for you, but with their own portfolio and their own interests.

What an in-house SDR really costs

It is not just the salary. You have to add the variable pay, Social Security contributions, the software and licenses they use, their training and the hours of whoever manages them. Published figures vary widely from one source to another, so before comparing, check recent ranges against a recognized salary study. If someone gives you a number with no source, be wary.

When an in-house SDR makes sense

• You already have a sales process that works and you can describe it.
• You sell a stable volume of accounts and the cycle repeats.
• Someone has time to train and manage them every week.

When an external sales team makes sense

• You want to start without building a team.
• You are opening a new market or channel, with a buying cycle you can identify.
• Your sales leadership would rather focus on negotiating and closing.

And contact lists, what about them?

They look similar, but they deliver something different. An unfiltered contact list is not a conversation. At Hurus, we deliver meetings with decision-makers, with the context of why we are writing to them now.

What your sales leadership still does

Everything that matters. Negotiating, closing and serving the customer stay in your company. The external team opens the door; you decide what happens on the other side.

How to know if it works: measure meetings, not messages

In the first 90 days, the number that matters is how many meetings with decision-makers you get each month. Messages sent tell you nothing. A team can send a thousand and not open a single conversation.

Frequently asked questions

How much does an SDR really cost in Spain? You have to add gross salary, variable pay, employer Social Security contributions, software and licenses, training and management. Published figures vary widely between sources, so it is worth checking recent ranges against a recognized salary study.

How long does it take an SDR to become productive? It depends on the product, the buying cycle and whether a process already exists. In long-cycle B2B sales, like food exports, they have to learn the product, the market and the buyer's language. Measure it in meetings with decision-makers per month.

Does an external team replace my sales director? No. The external team opens conversations and books meetings with decision-makers; negotiation, closing and the customer relationship stay in your company.
