Adding advisory services — without headcount.

Firms add advisory services in one of three ways: hiring advisory specialists, training the compliance team, or putting software behind the team. The first two scale with people. The third changes the economics, because the analysis is produced by the system and reviewed by the partner or manager who already knows the client.

01

Why the compliance-only model is under pressure

Automation has absorbed much of the recurring compliance work, and clients increasingly arrive with forward-looking questions the annual accounts were never built to answer: can I afford this hire, will the bank fund me, is my pricing right. Firms that only report history end up competing on price for the most automated part of the job.

The demand for advisory is already in the room. What is missing, in most practices, is the capacity to answer it inside a fee that works.

02

The three ways firms add advisory

  • Hire advisory specialists. Fastest to capability, slowest to margin. The headcount is added before the client demand is proven, and it becomes a fixed cost through every quiet quarter.
  • Train the existing team. Credible and leveraged, because those people already know the clients. The capacity comes out of the same team doing the compliance work, so progress is slow and stalls in every busy season.
  • Put software behind the team. The analysis is produced by the system and reviewed by the manager or partner who owns the relationship. Capability arrives without a hiring decision, and the hours between raw numbers and advice collapse.
03

What do clients ask for first?

The first advisory work a client buys is rarely a strategy project. It is an answer to a decision already sitting in front of them — which is why the four questions below account for most of the demand:

  • Can I afford this hire? A cash question: the month the decision becomes safe, and the dip it creates first.
  • Will the bank fund me? A lender readiness question: how underwriters see the business today, and how long it takes to change that view.
  • Is my pricing right? A margin question: what the market bears, product by product, and the profit effect of each move.
  • What do the next two quarters look like? A forecasting question: best, expected and worst cases with the numbers attached.

Answering them well asks three things of a practice: the client's numbers read forward, a scenario or two with the numbers attached, and a brief the owner can decide from. None of that is new to you. What is new is the time it takes — and therefore the fee that makes it viable.

04

How should firms price advisory work?

Two models hold up: a fixed monthly retainer per client, or a project fee tied to a decision. Both are defensible on value rather than hours, because the client is buying a decision well made, not the time it took to reach it.

The anchor is already in the market — a part-time CFO costs around £3,000 a month, and clients understand that number as the price of this category of thinking. Set your retainer against what the client is deciding, not against the minutes the analysis took, because the minutes are precisely what software has changed.

05

Where AI changes the economics

An AI CFO changes the arithmetic at the point where advisory work stops scaling: the reading. The analysis is produced once, by the system, and reviewed by the professional who signs it. Your team stops rebuilding numbers from raw exports and starts reviewing, framing and delivering them — which is the part clients actually pay for.

That is how a portfolio of advisory clients can run without a matching portfolio of hires. Oak is being built in London by Oakmont Kingsley Ltd for exactly this, and we are keeping the detail until launch. Leave your email below and you will see it first.

Answers

Common questions, answered plainly.

Only if you want one. Software behind the existing team lets the manager or partner who already knows the client produce and review the analysis themselves, which means the first advisory engagements do not have to wait for a recruitment cycle.

No. The relationship is the firm's, and it is the reason the advice lands. The tools produce the reading, the scenarios and the brief with the reasoning shown; the judgement, the framing and the delivery stay with the people who own the client.

Structurally, not by convention. Ask any provider whether separation is enforced at the database layer, who can open which client inside a shared workspace, how data is encrypted, and whether client data is ever used to train models for other customers.
