Four Ways to Buy Advice: Reading a Consultancy Proposal in 2026
A finance director I worked with once laid three consultancy proposals side by side and asked a perfectly reasonable question: why is one £18,000, one £64,000 and one a monthly retainer of £9,500? The honest answer was that the three firms were selling different things, and only one of the proposals said so.
Fee structures are not administrative detail. They encode who carries the risk, how the work will be governed, and what happens when the scope moves. Read the pricing page as a description of the working relationship, and much of the mystery disappears.
Day rates: buying time, and hoping
The traditional model. You buy a consultant's day at an agreed rate, with an estimate of how many days the work will take. It is transparent, easy to benchmark and quick to arrange.
What it actually buys is effort, not outcome. The commercial incentive runs toward more days, not faster resolution, and the estimate is not a commitment. That does not make day rates wrong — for diagnostic, exploratory or genuinely open-ended work they remain the most honest structure available. But if you are commissioning a well-understood deliverable, a day rate transfers very little risk to the supplier, and you should price that in.
Watch for day rates quoted for a blended team without a breakdown of seniority. The number is meaningless until you know who is doing the work.
Fixed fees: buying a defined result
A fixed fee promises a deliverable for a stated sum. The consultancy absorbs the risk of overrun. For the buyer this is the most comfortable structure, and it is increasingly common in the mid-market as firms compete on certainty.
The trade-off sits in definition. A fixed fee is only as good as the scope attached to it, and scope documents written by the supplier tend toward the narrow. Read the assumptions and exclusions with more care than the price. A proposal that excludes stakeholder interviews, or travel outside the M25, or a second round of revisions, has not fixed anything — it has fixed the first stage.
Fixed fees also tend to attract a contingency premium. You are paying, in effect, an insurance charge. On a well-specified piece of work that is reasonable; on a speculative one it can be 20 per cent of the fee for a risk that never materialises.
Retainers: buying access and continuity
A retainer buys a standing relationship — an agreed number of days or a defined service each month, usually at a discount to the standard rate. For organisations with a steady flow of decisions, it removes the friction of commissioning work afresh each time, and it gives the adviser enough context to be genuinely useful.
The risk is drift. Retainers can quietly become a subscription to a familiar face, with activity reported but value unexamined. Insist on three things: a stated monthly deliverable rather than hours, a review point at six months, and a notice period short enough to be a real option. A retainer you cannot leave is a payroll cost.
Value-based and outcome-linked arrangements: buying a share of the upside
These tie some or all of the fee to a result — cost saved, revenue gained, a transaction completed. On paper they align interests neatly. In practice they are only as sound as the baseline.
Before agreeing, establish who measures the outcome, on what data, over what period, and what happens if the result is delivered but the market moves against it. Value-based work suits situations where the gain is measurable and attributable. It suits them badly where causation is contested, which is most of the time in commercial settings. Be sceptical of any arrangement in which the definition of success is written by the party being paid on it.
Reading the proposal: four tests
Once the models are understood, comparisons become manageable. Four tests do most of the work.
- Anchor. Does the proposal connect the fee to a business problem with a number attached — margin, cycle time, staff turnover, cost per transaction? A fee with no anchor is a price without a purpose.
- Accountability. Who is named, at what seniority, for how many days? What happens if the lead consultant is unavailable, and what are the payment terms if the work slips?
- Clarity. Are assumptions, exclusions, expenses and change control stated plainly? Are governance and reporting described? Vague proposals are rarely good value, whatever the rate.
- Exit. How does the engagement end, and what do you keep? A good consultancy leaves capability behind — documentation, a model, trained people — not dependence.
| Question | Weak answer | Strong answer |
|---|---|---|
| What changes? | Improved processes | Invoice cycle from 41 to 28 days |
| Who delivers? | Our experienced team | Two named consultants, 60 per cent senior |
| What if scope moves? | We will discuss it | Written change note, priced, approved before work |
| How does it end? | Ongoing support available | Handover pack and two training sessions included |
Red flags that survive any model
A single all-in figure with no team composition. Expenses described as to be agreed. No named individuals. A success fee whose baseline is not yet defined. A proposal that answers a question you did not ask. And, most common of all, a document that describes the firm's methodology at length and your business hardly at all.
Judgement is the product
None of this argues for the cheapest quote, or the most detailed one. It argues for comparability. Price the risk transfer, price the seniority, price the exit, and the numbers start to mean something.
You are not buying days of a consultant's life. You are buying judgement applied to a decision that matters, under terms you understand well enough to hold someone to. A proposal that makes those terms explicit is worth a premium. One that obscures them is not worth the discount.
