Built forone decision, not for general use
Assumptionsvisible and editable, never buried
Yoursthe file, the logic and the workings

PRICED BY THE HOUR

$60 to $120

Scoped against the decision you are making. One-off, and quoted before we start.

You are probably here because one of these is true.

You have a decision to make and no way to test it.
An investor has asked for a model and you have a spreadsheet.
You do not know what a new hire actually costs you across a year.
You are changing prices and cannot see what it does to contribution.
You need to know how long the cash lasts under three different scenarios.
You have a model, but nobody can explain where its numbers come from.

Which version you need.

A model is built backwards from the decision. Tell us the question and the shape follows from it.

ONE QUESTION

Decision model

  • One decision modelled
  • Scenarios you can switch between
  • Assumptions on one sheet

Days to weeks

THE WHOLE BUSINESS

Operating model

  • Revenue built from drivers, not growth rates
  • Cost base modelled properly
  • Rolling cash and runway
  • Scenario and sensitivity switching
  • Unit economics and breakeven

Weeks

FOR A ROOM

Investor-facing model

  • Everything in the operating model
  • Built to survive diligence questions
  • Comparatives consistent with your history
  • A version you can present from

Scoped around the raise

What is in, and what is not.

Included in every model

  • Forecasting built from drivers rather than a growth percentage
  • Scenario and sensitivity analysis you can switch between
  • Cash flow and runway under each scenario
  • Unit economics and contribution by product, channel or segment
  • Breakeven analysis, and what would have to be true to reach it
  • Pricing analysis where the decision is a price change
  • Investment and hiring analysis where the decision is a spend
  • A walkthrough of the logic, so you can defend it without us in the room

Not included

  • A forecast presented as a prediction. A model shows consequences of assumptions, not the future
  • Assumptions we invent. They are yours, we make them explicit and we will challenge them
  • Investment advice, or a view on whether to raise. That is not a service we are licensed to give
  • Tax modelling and tax planning. Your practitioner, in your jurisdiction
  • Ongoing maintenance, unless you want it. A model that nobody updates is a snapshot
HOW IT RUNS

Five stages, starting with the decision rather than the spreadsheet.

A model that cannot be explained in a meeting is not finished. The last stage is you being able to defend it without us.

1Define the decisionWhat you are actually deciding, what would change your mind, and what the answer has to look like.FIRST CONVERSATION
2Agree the driversWhat the business actually runs on, and which assumptions are yours to set rather than ours to guess.FIRST DAYS
3BuildStructured so the assumptions sit in one place and the logic can be followed by someone who did not build it.THE BULK OF IT
4Stress itScenarios, sensitivities and the cases you are worried about, run before you see it rather than after.BEFORE HANDOVER
5Walk it throughA session on how it works and where the numbers come from, so you can defend it yourself.ON HANDOVER

What you have at the end.

Named artefacts, not adjectives. Everything below is something you can open, forward or hand to a third party.

The model itselfYours to keep, edit and reuse. No locked cells, no black boxes.
An assumptions sheetEvery input in one place, labelled, sourced and editable.
Scenarios you can switchBase, upside and the case you are actually worried about.
A cash and runway viewHow long the money lasts under each set of assumptions.
Unit economicsWhat a customer, a product or a channel actually contributes.
A walkthroughSo you can present it and answer questions without us in the room.

WHO DOES THIS WORK

A named senior accountant

ACCA-qualified · Modelling and advisory · Reviewed by Quality Assurance

Models are built by ACCA-qualified senior accountants who work in the underlying books, and are reviewed independently before handover. Excel is used daily here: pivot tables, complex lookups and macros where automation earns its place, though a model nobody can read is a failed model regardless of how clever it is.

WHAT IT COSTS

$60 to $120 an hour, scoped against the decision.

The rate is the highest we publish because it is the most senior work we do. What keeps the total reasonable is scope: a model built for one decision is much smaller than a model built in case anyone ever asks anything.

Price your ongoing bookkeeping instead
How many decisions it has to serveOne question is a small model. A general-purpose one is not.
How the revenue worksSubscription, transactional, project or mixed. Mixed is the expensive one.
Whether the history is reliableA model built on unverified actuals inherits every error in them.
Who has to read itA model for you is simpler than one that has to survive diligence.
Scenario depthTwo cases or eight, and how many levers move independently.

Questions we get asked.

Advanced, and used daily. Pivot tables for summarising and analysing large datasets, complex formulas and lookups, and macros to automate repetitive work. We build financial models, reporting tools and automation templates for clients as part of our modelling service.

No, and be careful of anyone who says otherwise. A model shows the consequences of a set of assumptions. Its value is that the assumptions are explicit, so you can argue with them and see what has to be true for the answer to change.

They are yours. We make them explicit, put them in one place, and challenge the ones that look optimistic, because an unchallenged assumption is where most models go wrong. What we will not do is invent a number and present it as a finding.

Yes. We have built financial models for investor pitches where funding was subsequently secured. The difference from an internal model is that it has to survive questions from people looking for the weak point.

That is the intent, and it is why the last stage is a walkthrough rather than a file transfer. Assumptions sit in one place, the logic is followable, and nothing is locked. If you would rather we maintained it, that is a separate arrangement.

Usually. What we need is a clear decision and someone who understands the operational reality. Where a model needs assumptions only you can supply, we will say so rather than fill the gap with a benchmark from a different business.

WHAT USUALLY HAPPENS NEXT

A model is a moment. The decisions keep coming.

Clients who build one model often find the useful thing was the conversation around it, which is what a CFO engagement is.
