What Should I Expect From a Sales Growth Consultant in the First 90 Days?

If you're considering bringing someone in to help fix sales, it's reasonable to want to know what the first three months should actually look like before you commit. There's a real difference between a consultant who diagnoses your business and one who arrives with a generic plan already written.

This is what a properly run first 90 days should contain, roughly in sequence, and what shouldn't be happening yet.

What should happen in the first two to three weeks?

Diagnosis, and only diagnosis. That means going through your actual numbers — enquiries, quotes, conversion rate, average order value, cycle length — along with sitting in on real sales conversations, reading recent lost-deal notes, and talking to whoever currently owns new business. Anyone proposing solutions before this stage is complete is guessing, however confident it sounds.

A reasonable expectation is a short written diagnosis at the end of this period: where the constraint genuinely sits, what evidence supports that, and what it would cost the business to leave unaddressed.

What should the diagnosis actually cover?

It should look across the whole commercial chain rather than jumping to the first obvious symptom. Is the constraint lead volume, lead quality, conversion, follow-up discipline, pricing, proposition, team capability, or simply that nobody owns new business consistently? Most businesses assume the answer before checking, and it's frequently wrong or only part of the picture.

A consultant worth paying should be willing to tell you if the honest answer is smaller and cheaper than expected — that's a sign of an accurate diagnosis, not a weak one.

What quick wins are realistic in the first month?

Genuine quick wins tend to come from fixing process gaps that already exist rather than new activity — working through a backlog of unanswered quotes, tightening how sales calls end, removing dead opportunities that are cluttering the pipeline, or adjusting how leads are qualified. These cost little and can show measurable movement within weeks, which matters for confidence in the wider engagement.

Be wary of anyone promising a large revenue increase in the first month. That timeframe is realistic for tidying up existing inefficiency, not for generating and closing genuinely new business.

What should the 90-day plan actually contain?

By the end of the period, you should have a written, prioritised plan: what's being fixed first and why, what success looks like for each priority, roughly what it will take in time or cost, and who is responsible for each part. It should be specific to your business — your numbers, your market, your team — not a template with your logo added.

It should also be honest about sequencing. Fixing lead generation before conversion is fixed usually means paying more to lose more prospects at the same rate — a competent plan says so plainly.

What shouldn't be happening yet?

Large structural changes — hiring, firing, big spend commitments, wholesale CRM replacement — are premature in the first 90 days unless the diagnosis has clearly and specifically justified them. A consultant recommending major, expensive change before finishing the diagnosis is working from assumption, not evidence.

Equally, if 90 days pass with no written diagnosis, no measurable movement anywhere, and no clear next step, that's a legitimate reason to ask hard questions about what's actually been delivered.

How should you judge whether it's working?

Look for evidence, not activity. Meetings held and documents produced aren't outcomes. The right test is whether you can point to at least one number that's genuinely moved — a conversion rate, a shortened cycle, cleared quotes converted to orders — and whether you understand, in plain terms, what's being prioritised next and why.

What does this look like as a structured engagement?

This is broadly the shape of a Commercial Growth Sprint — a fixed-fee, time-bound diagnosis (£1,495 + VAT) that identifies where growth is genuinely being lost and sets out what to do about it, before any larger commitment is made. It's designed specifically for the situation described above: wanting a proper diagnosis before deciding on bigger, more expensive change.

If you are not yet sure which of these problems you actually have, the Sales Help for Founders & Business Owners hub is a useful starting point before engaging anyone.
