Let me describe a scenario you'll recognise.
A client finishes a twelve-week engagement with your firm. The strategy is sharp. The recommendations are genuinely good - the kind of work that changes how the client thinks about their business. The final presentation lands well. There's applause, or at least the consulting equivalent: serious nodding and a "this is really helpful."
Six months later, when they need help with the next problem, they call someone else.
Not because the work was bad. The work was excellent. They'll tell anyone who asks. But when the moment came to pick up the phone again, something stopped them. Maybe it was the memory of three weeks mid-project where nobody told them what was happening. Maybe it was the jarring switch from the partner who sold the work - the one who understood their business, who they trusted - to an unfamiliar delivery team they'd never met. Maybe it was the way the relationship just... evaporated after the final invoice.
Whatever it was, the feeling was enough. They went elsewhere.
I've lost clients this way. Not because the work was wrong - in one case, the client told me eighteen months later that our recommendations had genuinely transformed how they operated. But we'd gone quiet at the wrong moment. A three-week stretch mid-project where the team was heads-down and I assumed no news was fine. It wasn't fine. The client had filled the silence with their own interpretation, and by the time we delivered the final deck, the relationship had already cooled in ways I didn't fully clock until they didn't return our calls.
That's the pattern I've seen play out across consulting firms of all sizes. It's one of the most expensive problems in the industry, and it's almost invisible because the feedback never comes back labelled as "experience failure." It comes back as "they went in a different direction" or, worse, it doesn't come back at all.
The quality of a consultancy's thinking and the quality of its client experience are two entirely separate things. Many firms that genuinely excel at the former are quietly haemorrhaging repeat work and referrals because of failures in the latter.
But our NPS is strong. Clients keep coming back. The experience is fine - our work speaks for itself.
I hear you. And I'd push back. NPS measures what clients are willing to say when asked. It doesn't capture the clients who simply didn't call back. Your renewal rate tells you about the clients you kept - it tells you nothing about the ones who drifted away without a word. The work does speak for itself. But the experience speaks louder than you think.
When we work with consulting firms on their client experience, the problems almost never live inside the engagement itself. The strategic thinking, the analysis, the recommendations - that's usually where firms invest their best people and their deepest attention. Fair enough.
The experience breaks at the seams. And there are four seams that come up again and again.
The handoff. The partner who sold the work built a relationship during the pitch process. They understood the client's business, their politics, their anxieties. Then the engagement starts, and a delivery team the client has never met walks through the door. A COO at a 200-person management consultancy described this to me last year as "the bait and switch that isn't a bait and switch." The partner hasn't disappeared maliciously - they're busy selling the next piece of work. But from the client's perspective, the person they trusted just handed them off to strangers. That first week sets the tone for everything that follows, and too many firms treat it as an administrative step rather than a relationship moment.
The communication cadence. Most consulting engagements have a formal update rhythm - weekly calls, fortnightly steering committees, whatever the governance structure dictates. The problem is what happens between those updates. Three or four days of silence can feel like an eternity to a client who's just committed a six-figure budget and staked their internal credibility on this project. They start wondering: is the team stuck? Are they behind? Have they found something worrying? The absence of information creates anxiety, and anxious clients become difficult clients. Not because they're unreasonable, but because you've left them to fill the silence with their own worst assumptions.
The visibility gap. This one drives operations leaders absolutely mad. A client who wants to know where they are in the project - what's been delivered, what's outstanding, what's coming next - shouldn't have to send an email and wait 48 hours for someone to pull together a status update. But in most consulting firms, that's exactly what happens. Project status lives in the delivery team's heads, or in a project management tool the client doesn't have access to. The client is essentially flying blind between formal touchpoints. And they're comparing this experience to every other service they use. Their accountancy firm has a portal. Their legal team sends automated milestone updates. Even their plumber texts when he's on the way. The bar has moved.
The post-delivery drop-off. The engagement closes. The final deliverables are handed over. There's a wrap-up call. And then... silence. Maybe a Christmas card. Maybe a LinkedIn like six months later. The relationship that was intense and high-touch during the engagement goes cold almost overnight. This is where referral revenue dies. A client who felt well looked-after during and after the engagement tells their peers. A client who felt forgotten the moment the invoice was paid does not.
If you're running operations at a consulting firm, I'd wager you've seen at least three of these four in the last quarter. Possibly all four.
There's a psychological reality here worth naming directly. A client's perception of the quality of your work is partly - sometimes significantly - shaped by how the engagement felt.
A project that ran smoothly, communicated clearly, and felt well-organised makes the work itself look better. The same set of recommendations, delivered through a chaotic engagement with poor communication and a confusing handoff, feels less reliable. Less trustworthy. Less valuable.
This isn't irrational. If anything, it's entirely reasonable. A client is buying judgement and reliability. If the experience of working with you suggests your firm struggles to organise itself, why would they trust that the strategic recommendations are well-organised? The experience and the output aren't separable in the client's mind - even if they're completely separable in yours.
Forrester's 2025 Global CX Index found that 21% of brands saw their CX scores decline, while only 6% improved. The vast majority - 73% - were unchanged. Standing still on experience isn't neutral. It's falling behind relative to the firms that are actively improving.
The commercial impact compounds. Forrester's research suggests retention rates increase roughly 5% for every 1% improvement in customer experience. Qualtrics data shows that CX leaders in B2B have twice the customer retention of non-leaders. In a consulting business, where a single retained client might represent £200k-£500k of recurring annual revenue, the maths gets uncomfortable quickly.
The temptation at this point is to turn this into a technology pitch. It isn't. Or rather, it shouldn't be.
Digital tools close some of the most common gaps efficiently and at relatively low cost. But they only work alongside process and people changes. A client portal that gives real-time project visibility is brilliant - unless nobody on the delivery team updates it, in which case it's just an expensive window into an empty room.
So here's what actually helps, in roughly the order I'd suggest tackling it.
Structured onboarding sequences. Before the first day of delivery, the client should know exactly who they're working with, what the first two weeks look like, how communication will work, and who to contact when they have a question. One firm we worked with built this as a three-email sequence triggered automatically when the SOW was countersigned - first email introducing the delivery team with photos and short bios, second outlining the week-one agenda, third confirming the communication rhythm and escalation path. Takes about a day to set up in HubSpot or any basic CRM. They told us it halved the number of "just checking in" calls they got in the first two weeks of an engagement. Most firms have nothing here, so even a basic version is a real step up.
Proactive milestone communications. The client should hear from you before they have to ask. When a milestone is completed, when a deliverable is ready for review, when the team is moving into the next phase - these updates should arrive proactively. Not because a project manager remembered, but because the system sends them. We've seen this done well with something as simple as a Notion project page that auto-emails the client when a status changes from "in progress" to "complete." It removes the silence-between-updates problem almost entirely, and clients notice immediately.
Client portals for visibility. Not a massive bespoke platform. Something simple - a shared Notion workspace, a ClickUp client view, a lightweight portal built on your existing CMS - that gives the client a view of project status, deliverables, key dates, and any outstanding actions on their side. 73% of B2B buyers now prefer to research and access information independently online. Your clients are the same people. They don't want to call someone to find out where their project is. They want to log in and see it.
Post-engagement follow-up workflows. A structured check-in at 30, 60, and 90 days after project close. Not a sales call - a genuine "how's the implementation going?" conversation, ideally from the delivery lead rather than someone in business development. This is where relationships are maintained and where the next piece of work naturally surfaces. It's also where most firms do absolutely nothing. I've spoken to partners at firms billing £10m+ annually who have no structured process for staying in touch with clients after close. None. The relationship just ends and they hope the client comes back.
That last one is the one that gets me, honestly. All that effort to win the work, deliver the work, and then just... nothing. It's like spending six months training for a marathon and then not bothering to cross the finish line.
Pick one recent engagement. A real one - ideally one that went well in terms of work quality but where the client experience wasn't as strong as it could have been. Map the client journey from proposal through to three months post-delivery. Not a theoretical journey - the actual one, with all its gaps and rough edges.
Then identify the three points where the experience was weakest. You probably already know what they are. Your delivery team definitely knows.
Fix the highest-impact one first. Not all four failure points at once. Not a firm-wide initiative. One fix, one engagement type, one quarter.
The barrier here is almost never capability or budget. It's awareness and prioritisation. Most consulting firms have never actually mapped the client experience as a journey. They've mapped the project. They've mapped the methodology. They've mapped the commercial terms. But the experience of being a client? That's been left to individual partners and their personal style, which means it's inconsistent at best and non-existent at worst.
If you want to map your own firm's client journey and identify where the experience is weakest, we've put together a consulting client journey audit template that takes about an hour to work through with your delivery team. It covers five stages - proposal, onboarding, delivery, close, and follow-up - against the most common experience failures at each stage. It's a useful starting point for an honest conversation. And the conversation itself is usually worth more than whatever comes out of the template.
The firms that get this right - that treat the client experience as seriously as they treat the quality of their advice - don't just retain more clients. They build the kind of reputation where the next engagement doesn't start with a pitch. It starts with a phone call from someone who heard about them from a client who couldn't stop talking about what it was like to work with them.
That's the dividend. And it compounds.
