Advisory: what it is, how it works and why it is (emphatically) not consulting

Advisory is an ongoing professional relationship in which an external counsellor, the advisor, supports a company’s owners, CEO and board in medium- to long-term strategic decisions. Unlike consulting, which solves a defined problem within a set timeframe, advisory does not produce outputs (deliverables) but outcomes (business results measurable over time). It is the work of someone who sits on the same side of the table as the decision-maker, not opposite.

In Italy the term “advisory” still creates a semantic short circuit, and Brand Advisory even more so. Many business owners automatically equate it with “consulting”, and the two terms are used as synonyms on agency websites, in tender specifications and even in some legal texts. The problem is that they are not the same thing, and confusing them leads to the wrong professional, the wrong budget and, above all, the wrong expectations about results.

1. What advisory is: definition, etymology and context

The operational definition

Advisory (noun and adjective, from to advise, “to counsel”) is the professional service of providing ongoing, high-level strategic advisory to decision-makers in an organisation. The Cambridge Dictionary defines it as the activity of “giving advice” in an official and regular capacity, typically carried out by an advisory board, a panel or a specialist firm.

The Treccani Dictionary records it as an anglicism now firmly established in Italian business vocabulary, denoting a firm specialising in high value-added consulting, often in finance, strategy, M&A, governance or brand.

Etymology reveals the nature of the profession

The Latin root is illuminating. Advise derives from the Old French avis (“opinion”), itself from the phrase ço m’est à vis, “this seems to me”. The ultimate origin is the Latin visum (past participle of videre, “to see”) and the Indo-European root *weid-, “to see”. Source: Online Etymology Dictionary (etymonline.com).

In other words: the advisor is the one who sees, who holds a vision that the client, immersed in day-to-day operations, cannot have. Not an executor. A long-term observer.

Keep this image in mind: it is the key to understanding everything that follows.

2. Advisory vs Consulting: the seven structural differences

The difference is not a “semantic nuance”. It is architectural. It changes the nature of the contract, the pricing model, the time horizon and, above all, the value produced.

Comparison table: Advisory vs Consulting

Let us look more closely at the three differences that most affect purchasing decisions.

2.1 Horizon: time changes the job

The consultant works like a sprinter: runs the 100 metres, crosses the line, leaves. The advisor works like a middle-distance runner who runs alongside you for years: they do not win the race for you, but they set your pace, correct your stride, and tell you when to push and when to recover.

Boston Consulting Group describes its model as “long-term, partnership-driven“: long-term relationships that often take the form of multi-year transformations rather than one-off projects. Bain & Company is renowned for its philosophy of “long-term client relationships and measurable results“, particularly in Private Equity. McKinsey & Company generates a large share of its global revenue through retained relationships with the boards and CEOs of Fortune 500 companies and with governments.

This is not marketing: it is how the service is structured.

2.2 Output vs Outcome: the difference worth millions

The consultant is engaged because someone already knows what is needed: a new CRM, a marketing plan, a financial analysis, a sales reorganisation. The question is “how”. The advisor is engaged because someone does not yet know what is really needed, or suspects that the right question differs from the one being asked. The question is “what” and “why”.

A practical example. A manufacturing company sees turnover fall by 15% over two quarters. The financial consultant opens the accounts, identifies the cost items that can be cut, and proposes reductions to recover margin. The symptom is resolved in 90 days. The advisor, by contrast, asks: “Why were customers buying from you five years ago, and why aren’t they today?”. They talk to sales, R&D, marketing and production. They discover that the positioning has eroded, and that the product is no longer premium but is still sold at a premium price. They set out a 24-month programme that redefines the business model. The consultant saved the quarter. The advisor saved the company.

Both professions are legitimate and necessary. They serve at different moments.

2.3 The position: in front or alongside

It is the most important metaphor in the sector. Deloitte has described its advisory approach as follows: “In Advisory, we do not take a defensive crouch. We move forward, defining the unknowns and framing the issues before you encounter them”. Put simply: the advisor anticipates the problems the client has not yet seen. It is preventive, not reactive.

This is exactly the difference between the family doctor who has known you for twenty years and the specialist you see for a specific test:

• the specialist (consultant) is excellent in their vertical field, sees you once, solves the problem and discharges you;
• the family doctor (advisor) knows your entire medical history, sees the symptom in context, and guides you through the lifestyle choices that will prevent the next illness.

Both are indispensable. But if you ask the specialist to act as your family doctor, you will get excellent performance on individual problems and no overall picture. If you ask your family doctor to operate on your heart, you have chosen the wrong professional.

3. The “Trusted Advisor”: the reference theoretical model

In 2000 David H. Maister, a former Harvard Business School professor and one of the world’s leading authorities on managing professional service firms, published The Trusted Advisor (Free Press, Simon & Schuster) with Charles Green and Robert Galford. The book, reissued in an updated edition in 2021, has become the international reference text for defining what distinguishes a consultant from an advisor.

Maister introduces the concept of the “trust equation”:

Trust = (Credibility + Reliability + Intimacy) / Self-orientation

Trust = (Credibility + Reliability + Intimacy) / Self-orientation

In other words: a consultant becomes an advisor when their technical expertise (credibility), their consistency in keeping promises (reliability) and the depth of their relationship with the client (intimacy) outweigh their drive to sell the next project (self-orientation).

This equation explains why many consultancies never manage to rise to advisory level: their commercial model is structurally geared towards selling the next engagement. The true advisor, by contrast, is willing to say “this time you don’t need me”, and it is precisely this restraint that consolidates trust over time.

4. The advisory market in Italy and Europe: the numbers

To understand where advisory is heading, you have to look at the data. Not opinions: figures.

Italy: management consulting is worth €7+ billion

According to the Assoconsult Management Consulting Observatory, Assoconsult being the trade association affiliated with Confindustria and with the European federation FEACO, the Italian consulting sector generated revenue of around €6.6 billion in 2023 (+14% on 2022), with over 26,000 firms and 66,000 professionals employed. Source: report published in collaboration with the University of Rome Tor Vergata, reported by Il Sole 24 Ore and MilanoFinanza.

For 2024, estimates point to further growth of more than 10%, which would take the market above 7 billion. The most dynamic segments:

• Strategy + IT consulting: together they account for over 40% of total revenue;
• Industry + financial services: together they generate almost 60% of demand;
• Consulting for the Public Administration: +30% (driven by the PNRR).

The figure that interests us most, however, is another: in the NetConsulting cube survey of 400 leading Italian companies (revenue > 500 million), over 85% perceive the value delivered by consulting as equal to or greater than twice the investment made. When it works, the ROI of advisory is significant.

Europe: the FEACO barometer

At European level, FEACO (European Federation of Management Consultancies Associations) publishes the annual Survey of the European Management Consultancy Market, which covers 14 countries including Italy, Germany, France, the UK and Spain. In the first months of 2024 the State of the Industry Barometer recorded a slight dip in sentiment (-3.5 points), though with growth forecast for the second half of the year.

According to Mordor Intelligence (2025 report), Digital/AI Consulting is the segment with the highest CAGR in Europe, 12.29% to 2031, driven by demand for AI roadmap design, data-platform integration and cloud migration. Sustainability and compliance (CSRD, DORA, NIS2) are the second growth driver.

Global: 466 billion dollars

According to Fortune Business Insights, the global management consulting services market was worth 466.68 billion dollars in 2024 and will grow at a CAGR of 5.63% to 2032, reaching 721 billion. North America holds 33.5% of the global share.

In other words: advisory is not a niche. It is one of the most significant professional industries in the world, and in Italy it is growing at a multiple of GDP.

5. When you need an advisor (and when you don’t)

Not every company needs an advisor at every stage. Here is the decision framework we use at Bliss to guide the companies that contact us.

You need a consultant if…

• you have a well-defined problem with a clear scope (e.g. implementing an ERP, conducting a due diligence, obtaining ISO certification);
• you already know which expertise you lack and need to bring it in-house for a defined period;
• the expected output is a concrete deliverable (a report, software, a process, a plan);
• the ROI is measurable in the short term (within the financial year).

You need an advisor if…

• you are facing a strategic decision with multi-year consequences (generational succession, M&A, in-depth rebranding, entry into new markets, exit);
• you are experiencing the so-called “loneliness at the top”: no one in the company has both the full picture and the authority to challenge your assumptions;
• the company is growing at double digits but the structure is creaking (the classic growing pain);
• you sense that the problems you see are symptoms, not causes, and you need someone to help you reframe the question;
• you want to build long-term value (enterprise value, brand equity, reputational capital), not just next quarter’s margin.

The seven typical situations in which advisory is critical

1. Generational succession (a central issue for Italian SMEs: over 65,000 businesses a year according to Confindustria data);
2. Buy-side or sell-side M&A (defining value, structure, deal narrative);
3. Positioning crisis: the brand no longer justifies its premium price;
4. Disorderly growth: the company generates revenue but does not scale;
5. Entry into international markets with unfamiliar competitive dynamics;
6. Digital or AI-driven transformation that requires redesigning the business model, not just adopting technology;
7. Managing a reputational or governance crisis that affects brand equity.

6. Engagement models: how an advisor is paid

Pricing is one of the most misunderstood aspects of the profession. Here we summarise the four most widely used models internationally.

6.1 Monthly retainer (Advisory as a Service, AaaS)

The client pays a recurring fee (monthly or quarterly) for ongoing access to the advisor, regardless of the hours actually delivered. It is the dominant model for long-term advisory: it puts value ahead of hours and discourages the “selling” of extra projects. It is the strategic equivalent of a family doctor subscription: you pay for availability and accumulated knowledge, not for the individual visit.

6.2 Fixed fee per phase

A fee is agreed for each phase of the strategic programme (e.g. audit, strategy definition, implementation). A hybrid model between consulting and advisory, used when the client needs predictable spending.

6.3 Success fee / outcome-based

Part (or all) of the fee is tied to achieving agreed KPIs. This is the typical model in M&A advisory, where the advisor receives a percentage of the transaction value. Mordor Intelligence reports that in 2025 62% of AI advisory projects at a large European integrator included success-linked fees.

6.4 Equity advisory

The advisor receives an equity stake (typically 0.5%–3%) in the company. A typical model for start-ups and scale-ups that lack the cash to pay top-level advisors but want access to their network and experience. Compatible with multi-year vesting.

7. The new frontiers: AI, ESG, CSRD

Advisory in 2026 is different from advisory in 2020. Three forces are reshaping it.

AI advisory

Generative AI adoption among European companies rose from 12% in Q1 2024 to 38% in December 2025 (source: McKinsey, State of AI 2025). 77% of European finance executives expect significant productivity gains from AI, and 68% anticipate a redefinition of roles (Mordor Intelligence). The consequence: a new category of advisory combining AI roadmap design, prompt engineering and, above all, compliance with the EU AI Act. The Big Four have announced investments in AI platforms of over 5 billion dollars by 2030.

ESG and CSRD advisory

The EU Corporate Sustainability Reporting Directive introduces 80 disclosure requirements and 800 data points, extending sustainability reporting to around 50,000 European companies from 2024 onwards. This has effectively created a new advisory specialism: double-materiality assessment and the integration of ESG metrics into capital allocation decisions. Regulation is, by its nature, classic advisory territory: a multi-year horizon, cross-cutting impact on every function, and decisions that top management cannot delegate.

Brand advisory and reputational capital

In a market where the brand is the main lever of pricing power, brand advisory has moved out of the creative sphere and into the financial one. International studies (Interbrand, BrandZ) show that brand value now accounts for 20-30% of the market capitalisation of listed companies in the consumer and luxury sectors. That is why, at Bliss, we have structured Brand Advisory as a service that speaks directly to CFOs and boards, not to the marketing manager.

8. How to choose an advisor: E-E-A-T criteria applied to business

The E-E-A-T principles (Experience, Expertise, Authoritativeness, Trustworthiness), developed by Google to assess the quality of web content, are in fact an excellent framework for assessing an advisor. Here is how to apply them in practice.

Experience (first-hand experience)

Has the advisor you are assessing already been through what your company is going through? Have they directly managed generational successions, M&A, premium brand repositionings? Vicarious experience, having read about it in books, is not enough. Ask for verifiable case studies and direct references from previous clients.

Expertise

Educational background, certifications (for example CMC, Certified Management Consultant, awarded by ICMCI/CMC-Global and in Italy by APCO-CMC), publications, research. A serious advisor invests constantly in their own knowledge: this is the credibility in Maister’s equation.

Authoritativeness

Is the advisor quoted, invited to speak, called upon as an expert witness? Does their voice carry weight in their field? Check for appearances in trade media, board memberships, and publications in academic or industry journals.

Trustworthiness

Transparency on the pricing model, conflicts of interest and the scope of the mandate. A serious advisor says no to mandates they cannot manage or that create conflicts. Be wary of anyone who accepts anything just to get the contract signed.

9. The most common mistakes when engaging an advisor

From our experience supporting the boards of premium and high-ticket companies, at Bliss we have identified five recurring mistakes:

1. Confusing advisor and consultant in the specification. An advisor is requested, but the brief is written for a consultant: deliverables, tight deadlines, operational outputs. The result: you pay an advisor to do a consultant’s work, wasting their main lever (vision).
2. Measuring advisory against operational KPIs. If you assess an advisor on the number of slides produced or meetings held, you have already lost. An advisor is measured on decisions avoided, opportunities captured and risks anticipated. Outcome measures, not activity measures.
3. No access to the top. An advisor without direct access to the CEO, the CFO and the owners cannot provide advisory. In practice, they become a very expensive consultant. The level of dialogue defines the service.
4. Unmanaged conflict of interest. Advisors who also sell the products they recommend (software, funds, insurance policies) are in a position of structural conflict. This does not mean they are dishonest; it means their client focus is structurally compromised.
5. Expecting results within the quarter. The value of advisory typically emerges between the sixth and the eighteenth month. Anyone looking for quick wins should hire a consultant.

10. FAQ: frequently asked questions about advisory

What is advisory, in a nutshell?

Advisory is a professional service of ongoing strategic support for a company’s CEO, board and owners, aimed at guiding medium- to long-term decisions. It differs from consulting in time horizon (years vs months), scope (strategic direction vs a defined problem) and type of output (business outcomes vs operational deliverables).

What is the difference between an advisor and a consultant?

The consultant has vertical technical expertise (hard skills) and solves a specific problem within a defined timeframe. The advisor has cross-functional expertise and supports the decision-maker in long-term strategic choices. The consultant works “in front of” the client as a supplier; the advisor works “alongside” the client as a peer. Both are necessary, at different moments and for different purposes.

How much does an advisory service cost in Italy?

Pricing varies according to the size of the client company, the advisor’s seniority and the engagement model. Indicative market ranges, based on Assoconsult data and market benchmarks, are: a monthly retainer of 5,000 to 50,000+ euros for multi-year advisory; a fee per strategic phase of 15,000 to 150,000+ euros; a success fee typically of 1%-5% of the value generated (for M&A or exits). Advisory boutiques tend to price below the Big Four for equivalent seniority.

Do the Big Four (Deloitte, PwC, EY, KPMG) do advisory or consulting?

Both, but in different ways. Deloitte formally distinguishes “Advisory” (more focused on risk, financial and regulatory matters) from “Consulting” (more strategy, operations and technology). PwC, EY and KPMG often use “advisory” as an umbrella term that also covers consulting. MBB (McKinsey, BCG, Bain) is classified as strategy consulting, yet its engagement model with top clients increasingly takes on advisory traits (long-term relationships, access to the board).

What is an advisory board?

An advisory board is an external consultative committee (non-statutory, and therefore distinct from the Board of Directors) made up of advisors selected for their expertise and experience. It supports owners and management on strategic decisions without holding formal governance powers. In Italy it is an increasingly common tool among SMEs in the scaling phase, as an alternative or complement to the traditional board of directors.

What is brand advisory?

Brand advisory is the branch of advisory dedicated to the strategic management of brand value as a financial asset and a lever of pricing power. It supports CEOs and boards in decisions on positioning, brand architecture, management of reputational capital and protection of brand equity over the medium to long term. It is Bliss Agency’s core service.

What is Advisory as a Service (AaaS)?

Advisory as a Service is the delivery model in which the client pays a recurring fee (monthly or quarterly) for ongoing access to the advisor, on a subscription basis. It replaces the “hours × rate” model with a “value × time” model. It has become the de facto standard for long-term advisory because it aligns incentives: the advisor earns more not by producing more hours, but by producing more value.

When do you NOT need an advisor?

It is not needed when you have a well-defined problem and already know what you need (in that case you need a specialist consultant), when your time horizon is shorter than 12 months, when the company already has a decision-maker with the vision and seniority an advisor could bring, or when you are not prepared to give the external professional access to strategic information and to top management.

11. In conclusion: advisory is not a fad, it is a discipline

If you have read this far, you will have grasped one thing: advisory is not a trendy English term for “slightly more serious consulting”. It is a distinct profession, with its own academic literature (Maister, Harvard Business Review), its own economy (over 466 billion dollars worldwide, 7+ billion in Italy), its own taxonomy of services and its own professional ethics.

The confusion between advisory and consulting is not a semantic debate. It is the confusion of an entire generation of entrepreneurs who, faced with long-term strategic problems, engage vertical specialists and then wonder why the symptoms keep coming back.

At Bliss Agency we have built a proprietary four-phase framework, Audit, Consulting, Advisory, Growth, precisely to avoid this confusion: each phase has its own role, its own metrics and its own engagement model. Advisory is the phase in which we sit alongside the CEO and the board to steer the decisions that, over the following twelve to twenty-four months, will determine the value of the company.

We don’t sell hours. We sell direction.

And the first thing we do with every new client is what you have just read: distinguish advisory from consulting. Because the first step to getting the right service is calling it by the right name.
