Business Plan Writers, Consultants and Advisors

People search for all three, and the difference between them is real: it changes what you get, what it costs, and whether anyone ever tells you the plan does not work. We sit in two of the three, and it is worth being direct about which.

A writer

Takes what you supply and turns it into a document. You provide the figures; they format and phrase them. That is the narrow version of this work, and it is not what happens here.

A consultant — this one

Works on the business as well as the document. The model is built rather than transcribed: assumptions tested, a sensitivity analysis showing which of them the business is genuinely exposed to, a break-even you can defend, and a risk section that says what could go wrong. If the analysis shows the plan does not work, you are told — which is most of what you are paying for.

An advisor

An ongoing relationship rather than a piece of work. We do not sell that, because the free routes are usually better value — try a Start Up Loans mentor or your local Growth Hub before paying anyone for an opinion on a draft.

What It Costs, and How Long It Takes

Both come down to the same thing: how much of the detail you already have
