Why cross-selling still fails and how to fix it | LexisNexis
Cross-selling should be one of the most dependable ways for mid-sized law firms to increase customer retention, strengthen loyalty and grow revenue from existing clients. Yet in practice, many firms continue to struggle. This article explores why cross-selling still fails in mid-sized firms and outlines practical, leadership-led steps to fix it.
Cross-selling fails when client experience fundamentals are weak
Successful cross-selling is built on trust. If clients feel poorly informed, experience delays, or believe advice is incomplete, they are unlikely to engage further with the firm. This is reflected in the Legal Ombudsman’s Annual Complaints Data and Insight 2024/25, which highlights poor communication, delay and failure to advise as the most common drivers of complaints.
These service issues directly undermine efforts to improve client relationships and make strategies to retain existing customers significantly harder to execute. For many mid-sized firms, the challenge is not technical quality but consistency. Without a reliable service baseline, cross-selling feels disconnected from client needs and risks eroding trust rather than reinforcing it.
Lawyers still perceive cross-selling as selling, not service
Behavioural resistance remains one of the biggest obstacles. According to Passle’s Cross Selling and AI in Legal Marketing Survey 2025, the majority of firms believe they are missing cross-selling opportunities, with lawyers citing concerns about appearing pushy, lacking time, or feeling uncertain about how to raise additional services.
The same findings, summarised in Passle’s Cross Selling and AI survey headlines, show that firms associate missed cross-selling with meaningful lost revenue each year. This mindset prevents the adoption of effective techniques of customer retention. When cross-selling is framed as solving adjacent client problems rather than selling, it becomes a natural part of service delivery.
Clients are often unaware of your firm’s full capabilities
Even where service delivery is strong, cross-selling can fail because clients simply do not know what else the firm offers. Research published by the Legal Services Consumer Panel shows that clients typically choose legal providers based on immediate need rather than a full understanding of firm-wide capability.
This is a particular challenge for mid-sized firms with broad practice coverage but limited brand visibility across service lines. If clients only associate the firm with one matter type, they will not instinctively return when new needs arise. Addressing this gap is critical to improving client relationships and unlocking sustainable ways to increase customer retention.
Structured end-of-matter conversations, sector updates and targeted client communications help firms demonstrate relevance without overt selling, supporting longer-term strategies to improve customer loyalty.
CRM data is underused in driving retention
Many firms have CRM systems in place, yet few use them to their full potential. Data that could support customer retention strategies in CRM often remains siloed or mistrusted by fee earners. As a result, cross-selling relies on individual memory rather than firm-wide insight.
The LexisNexis Bellwether 2025 report highlights that firms facing margin pressure are increasingly focused on deepening existing client relationships rather than relying on new instructions alone. Firms that succeed use data to anticipate client needs and support timely, relevant conversations, rather than treating CRM as a marketing-only tool.
Fixing cross-selling starts with retention-led thinking
Effective cross-selling programmes prioritise retention over revenue. The objective is to deepen relationships, not increase pitches. Firms that succeed embed cross-selling into service delivery, communication standards and matter management processes.
This includes training lawyers on how to improve customer engagement through value-led conversations and aligning incentives around client satisfaction. Access to practical, cross-practice insight also plays a role. Solutions such as Lexis+ Practical Guidance help lawyers quickly understand related issues outside their core specialism, enabling confident discussions that genuinely add value.
Leadership behaviour determines whether cross-selling sticks
Ultimately, cross-selling outcomes reflect leadership priorities. Managing partners who encourage shared client ownership and reward collaborative behaviour create the conditions for sustainable change. When cross-selling is positioned as part of delivering better client outcomes, it becomes one of the most effective strategies to retain existing customers.
As client expectations continue to rise, firms that invest in collaboration, data and service consistency will be best placed to respond. Cross-selling does not fail because clients reject it. It fails when firms do not align culture, systems and leadership around the client experience.
