In-House SDR or Account-Based Selling? How to Choose for Your Key Accounts

An in-house SDR is an employee who prospects for your company, usually across a wide list, and hands on first meetings. Account-based selling puts a dedicated team on a short list of named accounts and works several people in each one. Hire in-house when your market is wide and you can manage the person. Choose account-based selling when a few large accounts decide your year.

What does an in-house SDR do?

A sales development representative finds people who might buy, contacts them by email, phone and LinkedIn and passes the interested ones to a seller. In-house means the person is your employee. They sit with your team, learn your product from the people who build it and can be coached every week. That closeness is the real advantage. The usual limit is breadth: one person is asked to cover a long list, so each company gets a short look.

What is account-based selling when you buy it?

Account-based selling starts with a decision about which companies you want as customers. A dedicated consultant researches each one, maps who decides and approaches several people with a reason that is true for that company. When one contact goes quiet, the work moves to the next relevant person in the same account. Bought as a service, the person, the researchers and the platform come together for a monthly engagement. The unit of work is the account, not the contact.

What does each one really cost?

The salary or the fee is the smaller part. An in-house SDR also needs recruiting time, tools, contact data, sending domains, a manager and weeks to learn your market. When they leave, what they learned leaves too. Account-based selling needs your time as well: to agree the account list, to approve the plan and to pick up the conversations it opens. We quote no prices here. Compare what each approach reports back to you, as well as what it charges.

When is an in-house SDR the better fit?

When your market is wide and your buyers are similar. When the sale is simple enough that one person can learn it in weeks. When you have a manager who can coach every week, and a plan to keep the hire for years. In that case the closeness of an employee beats a service, and you build a skill inside the company that stays.

When is account-based selling the better fit?

When a handful of large accounts decide your year, several people in each must agree and you do not have a person who could build this inside the company yet. A new SDR asked to work hundreds of companies cannot do deep work in any of them. A team given 30 or 40 named accounts can. The model also suits a company that wants conversations inside key accounts this quarter, not after a hiring cycle.

Can you use both?

Yes, and many companies should. Split the market first. Give your named accounts to the account-based team and keep them out of the SDR's queue, so nobody contacts the same person twice. Let the in-house SDR work the wide list, the inbound replies and the smaller buyers. Agree one rule in advance: when a reply comes from a named account, it goes to that account's owner.

How does Intandemly work?

Intandemly is an account-based selling company, working this way since April 2017, almost ten years. Each client gets an ABX platform and a dedicated account-based selling consultant, supported by researchers, working a named list of key accounts agreed with you. We are not a staffing firm and we do not place SDRs in your team. We do not promise a number of meetings. We report on five KPIs: outreach accounts, coverage rate, active buying committees, active conversations and the value of pipeline generated.

  4. Question 4Can you wait for a hire to learn your market before results?Yes points to In-house SDR
  5. Question 5Would a poor first message to a key account cost you the account?Yes points to Account-based selling

Yes to questions 1, 2 and 5 points to account-based selling. Yes to questions 3 and 4 points to a hire. A mix of both points to doing both.

Common questions

Is it cheaper to hire an in-house SDR or use account-based selling?

The fee is the smaller part of the comparison. An in-house hire adds recruiting, tools, data, a manager's time and a ramp. Account-based selling adds your time to agree the list and follow up conversations. Intandemly works on a monthly engagement. To see how it compares with a hire, talk to us.

How long does a new in-house SDR take to become useful?

Allow weeks to learn your product and market, and longer when the buyers are senior. This is our judgement, not an average.

Can an in-house SDR work named accounts?

Yes, if they are given a short list and the time to research each account. If the same person is also set a volume target, the target tends to win and the accounts get a quick look.

Is Intandemly an outsourced SDR provider or a lead generation company?

Neither. Intandemly is an account-based selling company: an ABX platform plus a dedicated consultant working your named account list.

Do you guarantee a number of meetings?

No. A meeting count rewards the easiest contact to reach, not the right one. We agree an account list with you and report on the accounts.
