Business Development Manager vs Sales Manager

Business Development Manager and Sales Manager are frequently used as if they were versions of the same job, and job adverts written under either title regularly ask for the other role's skills. This matters because the two are not close substitutes. One is an individual contributor whose job is to win new business; the other is a people manager whose job is to lead a team and run a process that produces predictable revenue. Hiring the wrong one for the actual gap in the business wastes a recruitment cycle and leaves the real problem unaddressed.

The confusion is understandable. Both titles sit in the commercial function, both are judged ultimately on revenue, and in very small businesses a single person sometimes does elements of both jobs out of necessity. But as a business grows past that point, treating the two as interchangeable becomes a genuine liability.

This article sets out what each role actually does, where the confusion comes from, and how to decide which one a business needs.

What each role owns

Business Development Manager

An individual contributor role focused on generating new commercial relationships from a standing start: prospecting, qualifying, running a sales process, and closing new business. A BDM's own quota and own activity are the measure of their performance, not the performance of anyone else.

Sales Manager

A people-management role accountable for the output of a team of salespeople. This includes recruiting and coaching the team, setting and enforcing a sales process, managing pipeline and forecast accuracy, and being accountable for the team's collective number rather than any single deal.

Where the confusion comes from

Job titles in commercial recruitment are not standardised, and businesses often reach for whichever title sounds most senior or most familiar rather than the one that describes the job. A business advertising for a 'Business Development Manager' sometimes actually wants someone to run its small sales team, because that person will inevitably end up supervising a junior hire or two as the team grows — but the core skill set for winning new business individually and the core skill set for managing others to do the same are not the same thing, and a strong individual seller is not automatically a strong manager of sellers.

When a business genuinely needs both

A growing sales function often needs both roles, but not necessarily at the same time or in the same order. The typical sequence is: a founder or a single Business Development Manager proves that new business can be won repeatably, the business hires a small number of additional salespeople or BDMs to scale that activity, and only once there is a team to lead does a Sales Manager become the right appointment. Hiring a Sales Manager before there is a team to manage is a common and avoidable mistake — it results in a senior salary spent on management of a headcount of one or two, work that a working sales manager or the founder can still do directly.

What failure looks like when the wrong role is hired

Hiring a Business Development Manager when the real problem is management shows up as a new individual contributor added to an already undermanaged team, with the underlying process and accountability problems untouched — the new hire either underperforms alongside everyone else, or succeeds individually while the rest of the team continues to drift. Hiring a Sales Manager when the real problem is that nobody is generating new business shows up as a manager with very little to manage: no team, no pipeline to review, and a job that quickly narrows into doing the prospecting themselves, which is not what they were hired, and are usually best suited, to do.

How to judge candidates for each

For a Business Development Manager, look for a track record of opening new accounts from cold, tolerance for a high volume of rejection, and the discipline to keep prospecting even when a pipeline looks healthy. For a Sales Manager, look for evidence of having improved a team's performance rather than simply having inherited a good one — ask what a candidate found when they took over a previous team, what they changed, and what measurably improved as a result. A candidate who can only describe their own selling achievements, with no account of developing others, is unlikely to be a strong Sales Manager whatever their individual sales record.
