How long should I give a salesperson to perform?

Owners ask this question wanting a number. Three months. Six months. A year. It is a reasonable thing to want — a fixed timescale is easy to plan around and easy to explain to the rest of the business. The honest answer is that a fixed number, applied regardless of the role, will be wrong for most of the salespeople you hire.

The right timescale depends on how long it genuinely takes a customer to buy from you, how much there was to learn before the salesperson could sell competently, and how much support they actually received while they were learning it. Get those three right and the timescale falls out of them.

Why a fixed number is almost always wrong

A salesperson selling a £2,000 product with a two-week decision cycle can reasonably be judged on results within three months. A salesperson selling a £150,000 capital project with a nine-month buying process cannot — three months in, they should not have closed anything yet, and judging them as if they should have is simply measuring the wrong thing at the wrong time.

The three-month and six-month rules of thumb people repeat came from somewhere, usually a fast-moving transactional sales environment. Transplanted onto a longer or more technical sale, they produce exactly the wrong decision — either firing someone who was on track, or leaving someone underperforming for far longer than the evidence justified.

Start with your actual sales cycle length

Look at your last ten to twenty won deals and work out, honestly, how long they took from first meaningful contact to signed order. Not the shortest one you can remember — the typical one. A realistic performance timescale is roughly one full cycle to reach competent pipeline generation, and closer to one and a half to two cycles before revenue results are a fair test.

If your average cycle is four months, judging a new salesperson purely on revenue at the three-month mark is judging them on deals that, statistically, have not had time to close yet — regardless of how good they are.

How complex is what they are selling?

A salesperson moving from selling a simple product to a technical, configured, or highly regulated one needs real time to become credible in front of a customer, not just time to learn a script. If a competent buyer can ask a question that exposes shallow product knowledge within the first five minutes of a call, that salesperson is not ready to be judged on outcomes yet — they are still learning the thing they are meant to be selling.

Genuinely complex, technical, or regulated propositions can reasonably add one to three months of pure ramp-up before results should be expected at all, on top of the sales-cycle allowance above.

What onboarding did they actually get?

A salesperson given a laptop, a login, and a 'good luck' on day one is being judged against an onboarding process that never happened. If the business has no structured induction — product training, shadowing existing customer conversations, a written account plan for their territory — a slow start says more about the onboarding than the salesperson.

Before extending or shortening a timescale, ask honestly: if this person had received proper onboarding, would they be further ahead than they are now? If the answer is yes, the fair response is to fix onboarding and reset the clock, not to conclude the person is wrong for the role.

Is the territory new, mature, or inherited?

A salesperson taking over an established territory with existing customer relationships and a live pipeline should show progress faster than one opening a brand-new territory with no prior activity in it. Building a pipeline from zero in an unproven market genuinely takes longer, and treating both situations identically produces an unfair judgement of at least one of them.

If the pipeline they inherited was thin, poorly qualified, or mostly stalled deals left behind by a predecessor, factor that in explicitly. They are effectively starting from zero even though the org chart says otherwise.

What should you actually be tracking from week one?

Waiting until the 'judgement date' to look at anything is the single most common mistake. From the first week, track leading indicators that predict revenue long before revenue itself appears: number of new conversations started, meetings booked, quality of the questions they ask in those meetings, and how their early pipeline compares in shape to a proven performer's pipeline at the same stage.

• Weekly new business activity — calls, emails, meetings booked, at a level consistent with the role.
• The ratio of conversations to qualified opportunities — are they finding real problems, or just talking to people?
• Pipeline shape at 60 and 90 days compared with what a competent performer's pipeline looked like at the same point.
• Quality of their account and deal notes — do they understand the decision-maker, process and timing on their live deals?
• Manager's own assessment from sitting in on calls or meetings, not just numbers on a spreadsheet.

A salesperson with weak activity and vague pipeline notes at day 60 is a genuine early warning sign, regardless of your sales cycle length. A salesperson with strong, disciplined activity and a well-qualified but not-yet-closed pipeline at the same point is very likely on track, even with zero revenue booked.

How much is management quality affecting the outcome?

If nobody has reviewed this person's pipeline, sat in on a call, or given specific feedback since they started, the timescale question is premature. Poor early performance in the absence of any real management input is at least partly a management gap, and it is worth being honest with yourself about that before setting a deadline that assumes competent coaching was happening throughout.

Setting milestones that actually mean something

Rather than one distant pass/fail date, set milestones tied to the stages a genuine deal actually goes through in your business — for example, a target number of qualified opportunities by day 60, a target number of proposals out by day 90, and a first close by roughly one sales cycle in. Missing one milestone is information. Missing all of them, with weak activity behind it, is a much clearer signal.

This also protects you from the opposite mistake — extending an underperforming hire indefinitely because 'the market is difficult' with no defined point at which that stops being an acceptable explanation.

When you have genuinely given it long enough

You have given a fair amount of time when the sales cycle has had room to play out, onboarding and support were actually delivered, leading indicators have been tracked and reviewed regularly, and the milestones set at the start have now passed. If all of that is true and performance is still weak on both activity and outcome, the timescale question has been answered honestly — and the next question becomes what to do about it, which is a separate decision.
