From Buzzword to Bottom Line
For years, “Trusted Advisor” has been the go-to phrase whenever service leaders describe the relationship they want with customers. It’s used in sales kick-offs, service strategy decks, and job descriptions for everyone from field engineers to key account managers. The trouble is that the more a phrase gets used, the less it tends to mean. Ask ten people in your business what a trusted advisor actually does differently, day to day, and you’ll likely get ten different answers — usually some version of “being really good at customer service.”
That ambiguity is a problem, because for suppliers of industrial equipment, components and solutions, the trusted advisor relationship isn’t a nice-to-have. It’s the difference between being treated as a replaceable vendor and being the partner customers call before they’ve even finished defining the problem. So it’s worth being precise. We define a trusted advisor as:
A service professional whose relationship with a client goes beyond basic transactional expertise. They act as a long-term confidant, providing holistic guidance to help customers make critical, informed decisions — operational or strategic. The goal, through that relationship, is to add more value to both parties through collaboration.
Two words matter most in that definition: “both parties.” This isn’t altruism, and it isn’t really about being liked. Done properly, it’s a commercial discipline that benefits the customer’s operation and your order book at the same time. This article explores how that plays out in practice — and what it actually takes to build it into an organisation rather than just hope for it.
What Separates a Trusted Advisor from a Good Problem Solver?
Every decent service organisation can fix things. That’s table stakes. What separates a trusted advisor from a competent technician is the quality of the conversation around the fix. Trusted advisors have a knack for steering every interaction toward a solution rather than getting stuck describing the problem. They lay out options and the trade-offs each one carries, rather than telling the customer what to think. And critically, they earn trust through consistency between what they say and what they actually deliver, not through persuasion techniques.
This only works if every interaction is engineered to produce three wins at once: a win for the customer, who moves a step closer to their goal in every conversation; a win for the business, through loyalty and follow-on revenue; and a win for the individual, who feels they’ve genuinely helped rather than just “sold something.” Miss any one of these and the model breaks down — push too hard for the commercial win, and you destroy the trust that made the relationship valuable in the first place. The Trusted Advisor knows how to manage mutual relationships between these three parties – including themselves!.
It also matters where in the organisation the role sits. A field engineer’s version of this is about presenting options, not closing deals — the moment a customer feels they’re being sold to mid-repair, the relationship sours. A salesperson’s version is closer to consultative selling: building credibility and rapport through the buying process itself. Conflating the two is one of the more common reasons these programmes stall — technical staff resent being turned into closers, and the trust that made them effective in the first place quietly erodes.
A one size fits all programme does not cut it. While it’s important to recognise that all great trusted advisor behaviours are built on a combination of Customer Communication, Problem-solving and Consultative Selling skill sets, the outcomes of these behaviours is subtly different depending on our strategy:
1. Service technicians and engineers need to build collaborative customer communication into their already strong problem Solving skills.
2. Customer facing technical support and management roles need to be able to have engaging conversations that lead the customer to value added solutions
3. Service Sales have to learn to use Solution Sales techniques to find new opportunities and close deals.
The Building Blocks: Fix Yourself, Fix the Customer, Fix the Situation
Telling technicians and engineers to “be more trusted advisor” rarely survives contact with a real customer site. What works is a more deliberate sequence, and it starts with self-awareness rather than customer-facing skills. Before anyone can read a customer’s situation well, they need to understand their own communication style, their triggers, and how to stay emotionally even when a customer is frustrated. A useful working rule: roughly two-thirds of any customer conversation should be the customer talking, one-third you — clarifying, acting, and explaining benefit, not filling airtime.
Only once that self-awareness is in place does it make sense to focus outward — understanding the wider business goal behind the whole exercise: building a relationship where customers are genuinely open to discussing how to get more value from their equipment, rather than feeling every visit is a sales pitch in disguise. That requires technicians to understand how their own company makes money, where they sit on the spectrum between pure support and active selling, and what customers in their specific industry actually value — which varies enormously between, say, capital-intensive process plant and high-precision lab instrumentation.
The mechanics matter too: easy access to customer history, a clear path for raising opportunities that doesn’t feel like a hard sell, and a simple way to close out low-value requests without pulling in a salesperson at all. And because this is a behaviour change rather than a one-off training day, it needs reinforcement: coaching from senior technicians, feedback loops that prove the effort is working, and recognition that not everyone is motivated the same way. Some engineers respond well to commission; most respond just as strongly to the satisfaction of having properly solved a customer’s problem.
Problem-Solving Is the Foundation, Not an Afterthought
It’s easy to assume technical staff are naturally good problem solvers because solving problems is their job. In practice, most have picked up ad hoc habits from mentors rather than been trained in disciplined root-cause analysis. The cost of that gap is larger than most organisations realise. Research from Cranfield University into “no-fault-found” events in aerospace found costs ranging from roughly one to 300 million dollars across the companies studied, with NFF accounting for up to 80% of reported failures in some cases — largely a result of swapping components to chase symptoms rather than diagnosing causes.
Embedding a common problem-solving language — the structured thinking behind tools like the 5 Whys, fishbone diagrams, or the 8D process used widely in automotive — does two things at once. It reduces the direct cost of misdiagnosis, and it reframes the technician’s job: not “fix the equipment” but “fix the customer’s situation,” which might mean recognising the real root cause is an operator training gap, a raw-material quality issue, or an environmental factor well outside the machine itself. That broader framing is, in itself, a trusted advisor behaviour — and as predictive analytics takes over more routine fault diagnosis, the technicians who add the most value will increasingly be the ones who can reason about the customer’s whole operation, not just the asset in front of them.
From Service Insight to Sales Outcome
The trusted advisor mindset doesn’t stop at the service desk. Research by RAIN Group into more than 700 B2B purchasing decisions, covering over $3 billion in buyer spend, found that the single biggest factor separating sales winners from runners-up was the ability to bring new ideas and perspectives to the customer. Eight or nine of their top ten winning factors map directly onto trusted advisor behaviours — listening, collaboration and a solutions focus, not negotiating tactics or product features.
This is part of why so many equipment and technology businesses have spent the last decade rebuilding sales functions around “customer success” rather than deal closing — a shift that started in software, where renewal and retention matter more than the initial sale, and has since spread into industrial and capital equipment businesses too. The logic holds regardless of sector: a sales process on its own doesn’t create trust. What creates trust is moving from “what do you need” — answered with a feature list — to “what do you need to be successful” — answered with an outcome. That single reframing turns a transactional, push-based sales conversation into a pulled, collaborative one, and it’s the same shift in language and mindset that makes the technician-side trusted advisor model work.
With Si2, we see this as being the Service Value Sales Approach,
which combines the notion of Solution Selling with the enabling mindset of the Trusted Advisor. Done well, customers move from a transactional type of relationship to that of a strategic partner, growing customer loyalty and ultimately profitability.
Case Study: Turning Engineers into Revenue Generators at Pitney Bowes
Some of the best evidence comes from talking to practitioners. For example we recently worked with Ian Barnes, Head of Service at Pitney Bowes UK on his Trusted Advisor Journey. He set out to formalise something that was already happening informally: customers trusted the engineers who serviced their equipment more than almost anyone else in the relationship, often having known them personally for years.
The starting point was deceptively simple — a change of language. The team replaced “customer” with “client” throughout, on the basis that “customer” implies a one-off transaction while the business wanted something durable. From there, engineers were given a direct stake in three revenue streams: equipment sales, consumables such as inks and paper, and chargeable service add-ons like expanded preventative maintenance, with commission funded by the relevant sales budgets rather than treated as an afterthought.
What made it work wasn’t the commission alone. It was the supporting structure built around it: conflict-handling training so engineers could navigate tricky conversations without it feeling like a sales pitch; a simple, fast escalation path from engineer to salesperson; lead “triage” so salespeople could trust a forwarded opportunity was genuine rather than wasting time chasing it; and constant feedback so engineers could see what happened to the leads they raised — without it, engineers quickly stop bothering to flag opportunities at all. Just as important were the human touches: joint customer visits between engineer and salesperson, monthly meetings where service and sales reviewed live opportunities together, and salespeople routinely calling the engineer before contacting the client, so the conversation already had a foot in the door.
The results were tangible. Average revenue generated per engineer rose by 45% after the programme was introduced, and in the first stable year following the pandemic, engineer-generated leads brought in over £2.4 million — roughly £57,000 per engineer. As Barnes puts it, getting the relationship between sales and service right is the precondition for everything else; reframing engineers as helpers solving a client’s problem, rather than salespeople in disguise, was what made them willing to engage in the first place.
Bringing It Together
None of this works as a slogan. “Trusted advisor” only becomes real when an organisation is precise about what it means in each role, builds the self-awareness and communication skills underneath it, treats problem-solving as a trainable discipline rather than an assumed competence, and connects the resulting customer insight to a sales process customers experience as collaborative rather than pushed. Done well, it isn’t a soft skill bolted onto the service function — it’s a measurable commercial capability, visible in retained contracts, lower no-fault-found costs, and revenue that didn’t exist before someone had the right conversation at the right moment.
