How to Create Strong Working Relationships with Clients

More than a third of UK businesses now use a different firm for advisory work, such as tax strategies, even when their own accountant offers the same product or service. Client relationships in accountancy are no longer based solely on compliance. They rely on trust, proactive communication, and a real understanding of the client’s business. Firms that neglect this are already losing work to competitors, often without noticing.

Key takeaways

• Client loyalty in accountancy is no longer guaranteed. Research from 2026 found that over a third of UK businesses now split advisory work across multiple providers, even when their existing firm could deliver it.
• Retention can be measured and is worth protecting. Industry benchmarks put a good client retention rate for accounting firms at 90% to 96%. Winning a new client typically costs five to seven times more than keeping an existing one.
• Proactive contact drives client satisfaction more than accuracy. ICAEW’s 2024 member survey found it was the most cited factor, ahead of technical competence.
• The move from compliance to advisory work is accelerating. Understanding a client’s wider business is now a core skill, not an optional extra.
• Relationship-building should be taught deliberately, especially to early-career staff. It cannot be left to develop on its own.

The accountancy profession is in the middle of a genuine shift. Research from Wolters Kluwer’s Future Ready Accountancy report, based on more than 2,700 professionals across 14 countries, found that 93% of firms now offer advisory as a core part of the business rather than an add-on. UK firms are moving in the same direction but more slowly: only 60% currently treat advisory as core, against a European average of 67% and considerably behind Denmark (77%), Spain (76%) and the Netherlands (73%).

This matters for positive client relationships specifically because compliance work, the traditional basis of most accountant-client contact, is exactly the part of the job being automated fastest. ICAEW’s research on the UK’s mid-tier firms found that 83% of managing partners and CEOs agreed the accountant’s role will pivot from compliance and reporting towards judgement, systems thinking and ethical oversight by 2030, and 71% agreed AI will let firms move up the value chain. As routine compliance work demands less relationship contact, the quality of the relationship itself becomes one of the few things a firm can still compete on.

The evidence suggests many firms have not caught up with this shift. A 2026 study of 500 UK businesses, carried out by Censuswide and commissioned by Ravical, found that more than a third of businesses using common advisory client services were getting that work done by a provider rather than their main accounting firm. This was the case even where their own firm already offered the same service. Clients are not necessarily leaving; they are quietly diversifying, which is arguably a harder problem to notice and fix.

What is a strong working relationship with a client?

A strong working relationship is one built on mutual trust, shared understanding of the client’s objectives, and consistent, professional client communication. In accountancy, this plays out differently to a purely transactional supplier relationship. A client who only calls their accountant once a year for a tax return is being served, but they are not necessarily in a relationship with an adviser who understands their business.

The distinction matters more as advisory work grows. A transactional customer relationship treats each compliance deadline, the annual accounts, the VAT return, the AML client due diligence refresh, as a discrete task. A relationship-driven one treats those same touchpoints as opportunities to understand what is changing in the client’s business and to flag things before the client has to ask. High-quality relationships share common characteristics: the client feels heard, the firm understands the client’s wider goals, and both sides are clear on what to expect from each other.

Professional boundaries still apply. A good client relationship does not mean an informal or unstructured one; it means a well-managed one, often still governed by an engagement letter and clear scope, where trust and clarity coexist rather than compete.

Why strong customer relationships matter

Investing in customer relationships is not just a cultural preference. It has a direct impact on retention and revenue.

Industry benchmarking puts a good client retention rate for accounting firms at 90% to 96%, and the cost of winning a new client is typically estimated at five to seven times the cost of retaining an existing one. Every client lost to a poor relationship, rather than a genuine mismatch in service, is an expensive problem to solve through new business alone.

Censuswide-Ravical research shows clients do not always leave outright when a relationship weakens. More than a third are already sourcing advisory work elsewhere while remaining a customer on paper. Retention figures can look healthy while genuine wallet share shrinks. Firms that only track whether a client stays or goes are likely missing this.

Client satisfaction is driven by proactive advice, not just technical accuracy or responsiveness. ICAEW’s 2024 member survey found it was the single most cited driver. Clients assume competence. What earns loyalty is being told about a relevant change before they have to ask.

The foundations of trust with clients

Trust in an accountancy relationship is built through consistent behaviour over time, not a single gesture.

Consistency and reliability matter most: clients need to know that deadlines will be met and that the quality of advice will not vary depending on who they speak to within the firm. Delivering on commitments, even small ones such as returning a call when promised, reinforces this every time it happens. Transparency and honesty become particularly important when something goes wrong. Accountability after a mistake, acknowledged clearly and paired with an explanation of how it will be corrected, tends to strengthen trust rather than damage it, provided it is handled openly. Maintaining confidentiality underpins all of this, and it carries particular weight in a profession bound by client due diligence and data-handling obligations; a single breach can undo years of relationship building.

The effect of getting this right is visible in real firms, not just in theory. Accountability Edinburgh, named Bookkeeping Firm of the Year at the 2025 Accounting Excellence Awards, credits a formalised client check-in process, built around genuinely listening to what clients say they need rather than assuming it, for a 96% client retention rate over the preceding 12 months. Mercia’s own experience points the same way: the firm retains 96% of its accountancy firm clients year on year, a figure that reflects trust built over a 40-year track record rather than any single service.

Communicating effectively throughout the client relationship

Communication quality shapes a client relationship at every stage, not just during onboarding. Evidence shows clients want firms to initiate contact rather than wait to be asked.

Active listening is essential. Clients notice quickly if an adviser is genuinely listening or just processing a request. Asking effective questions uncovers detail that leads to better advice. Plain language works better than jargon when explaining technical or regulatory information. A client who does not fully understand a point on capital allowances or Making Tax Digital cannot act on it with confidence.

Proactive updates are as important as responsive ones. Flag regulatory changes as soon as they are relevant, rather than waiting for a client to ask. Choose the right channel: some clients want a quick call for urgent matters, others prefer email or a portal message. Set and manage expectations about response times, for example, confirming that queries will usually be answered within one working day. Firms that set this standard consistently give clients a predictable experience, regardless of who they are working with.

Understanding client needs and objectives

Moving from service provider to trusted adviser starts with genuinely understanding the client’s business. This is now a professional necessity, not just a point of differentiation.

As compliance work automates and advisory work grows, in this case, ICAEW’s mid-tier research found 83% of firm leaders expect the profession to shift towards judgement and interpretation. A firm’s value increasingly rests on understanding what a client is trying to achieve, not just producing accurate figures. This means learning about the client’s goals beyond the immediate assignment: what they are trying to build, what challenges they are facing, and how they make decisions. A firm that understands a client’s strategic objectives can spot opportunities and risks the client has not yet raised, rather than only responding to what is asked.

Tailoring advice to the client’s specific circumstances, rather than offering generic guidance, is what distinguishes a trusted adviser from a transactional supplier. This kind of value is hardest for a competitor or software to replicate.

Setting clear expectations from the start

Most relationship problems can be traced to unclear expectations set at the outset. Accountancy has a natural advantage: the engagement letter is the formal mechanism for setting expectations.

Clarity is needed on the scope of work: what is included, and just as importantly, what is not. Timelines and deadlines should be agreed and realistic, particularly around statutory filing dates rather than aspirational internal targets. Service standards, such as how quickly queries will be answered, should be stated rather than assumed. Roles and responsibilities need to be clear on both sides; clients have obligations too, such as providing records promptly enough to meet a filing deadline.

Unclear scope is a relationship risk and an operational one. Work that creeps beyond the agreed engagement without a fee conversation erodes margin on every file, not just the difficult ones. Recurring compliance touchpoints, such as the annual AML client due diligence refresh, are a natural opportunity to revisit scope and expectations.

Common challenges that damage client relationships

Several recurring issues erode good relationships. Most are avoidable. Missed deadlines and delayed responses are consistently cited as bigger drivers of dissatisfaction than technical errors. Missed deadlines damage confidence quickly, particularly when they are not flagged in advance. Overpromising and underdelivering, whether on timelines, outcomes or availability, sets up a relationship to fail from the start.

A lack of understanding of the client’s business leads to advice that feels generic rather than relevant. This is increasingly what separates a firm from its advisory-focused competitors. Failing to address concerns promptly, even minor ones, signals to a client that they are not a priority. The loss of trust that follows a poorly handled mistake is often more damaging than the mistake itself.

Managing difficult partner conversations professionally

Client partnerships eventually involve a difficult conversation. How it is handled matters more than the news itself.

Delivering difficult news works best when it is direct, timely and paired with a proposed solution rather than delivered without context. Discussing errors or delays requires being honest about what happened and what will be done differently, in keeping with the professional and ethical standards the profession already holds advisers to, rather than minimising the issue. Handling disagreements calmly, focusing on facts rather than defensiveness, tends to preserve the relationship even when the client is frustrated.

Managing unrealistic client expectations is easier when it happens early, before a client has built plans around something that is not achievable, such as a filing timeline that does not allow for the records still outstanding. Maintaining professionalism under pressure and focusing on solutions, not blame, keeps the conversation constructive.

How strong client relationships develop over time

Client relationships in accountancy move through recognisable stages. They do not stay fixed.

Early-stage relationships focus on establishing credibility, often through the quality of the first compliance cycle and how reliably commitments are met. As the relationship matures, trust deepens through consistent service delivered across multiple filing years. At this stage, many advisers begin the transition from provider to trusted adviser, being consulted on decisions well before any formal engagement is agreed.

This transition is becoming harder to leave to chance. ICAEW’s research suggests firms expect AI to reduce demand for entry-level compliance tasks, the work that has traditionally taught junior staff how client relationships function. A junior accountant may be well prepared to complete a file but poorly prepared for their first difficult client conversation, because the apprenticeship model that once taught this alongside technical work is shrinking. Practices that build relationship and communication skills into early-career development deliberately are likely to produce advisers who reach the trusted-adviser stage sooner.

Measuring the strength of client relationships

Relationship strength can be tracked, not just assumed. This matters more as clients can look loyal while quietly moving advisory work elsewhere.

Indicators of clients' trust include how openly a client shares information and how quickly they respond to requests. The quality of communication, judged by clarity and responsiveness rather than frequency alone, is another useful signal. Repeat business and a client’s willingness to expand the scope of work both point to a healthy relationship, as do referrals, since happy clients rarely recommend an adviser they do not fully trust.

Structured client feedback, gathered through regular check-ins or periodic reviews, provides more reliable insight than assumptions. Firms such as Accountability Edinburgh credit this practice for their retention performance. Given the evidence that clients can diversify their advisory spend without formally leaving, a relationship review should ask not only “are they still a client” but “are we still doing all the work we could be doing for them.”

Practical actions to strengthen client relationships

Turning these principles into practice does not require a major overhaul. Consistent habits are enough.

Scheduling regular check-ins, even brief ones, keeps a relationship active between formal compliance deadlines. Personalising communication, referring to a client’s specific circumstances rather than sending generic updates, shows genuine attention. Documenting client preferences, such as preferred contact methods or key dates in their business calendar, allows a team to deliver consistent service even when the usual point of contact is unavailable.

Following through on commitments, however small, is one of the simplest and most effective ways to build trust over time. Seeking feedback regularly, rather than waiting for a problem to surface, gives a practice the chance to improve before a client relationship comes under strain or before advisory work drifts to a competitor. None of these actions is complex, but together they build the kind of client relationship management that supports long-term retention and growth.
