Cross-selling has been one of the most persistent barriers to growth in certified public accounting (CPA) and advisory firms—particularly as firms invest more heavily in advisory services.
Over the years, we’ve seen a range of tactics used to crack the code: service line spotlights, internal training, customer relationship management (CRM) implementations, gamification, and a mix of incentive programs. Some show flashes of success, but for most firms, the results are temporary. That’s because the cross-sell challenge isn’t simply about tools or tactics—it’s structural, cultural, and personal.
To make progress, we must stop asking how we can better cross-sell and instead ask, “What would have to be true about our structure to holistically serve the client?”
Serving clients with multidisciplinary solutions requires a shift that affects every aspect of a firm’s design and mindset—you have to flip your perspective from what services you sell to what problems you can solve.
To be a truly client-centric firm, these are the foundational characteristics you need to adopt:
Most firms still organize primarily by service line. From an internal lens, it makes sense. It’s how we manage delivery, develop technical talent, and track financial performance. But from the client’s perspective, it creates disjointed experiences, missed opportunities, and stunted growth. Service line structures foster siloed thinking—and that’s where cross-selling dies.
In many firms, the relationship executive (RE) is assigned based on the first service delivered. For example, if the first engagement is an audit, the RE is an auditor. If it’s a valuation, the RE is an advisor. The problem with this approach is that the initial service provided to a client often dictates the lens through which they see the entire firm. As one CPA firm partner said bluntly, “We’re great at selling additional services within our department—not across them.”
To solve this, firms need to shift their mindsets from selling services to solving problems and back it up with structural change.
So, what structural models best support client centricity? I believe most CPA and advisory firms would benefit from a hybrid approach, using a combination of the common models shown in the chart below. Typically, combining service line infrastructure with either industry specialization or client account teams works best.
This dual-accountability model gives you the best of both worlds: depth of technical expertise and breadth needed to understand and address the client’s full business needs. It also aligns with how clients think—holistically, not functionally.
Client-centric delivery starts with how we form and manage client teams. For instance, many progressive firms are now adding client success managers (CSM)—often from customer service or account management backgrounds—and making them the first point of contact. The CSM partners with the RE to manage the overall relationship, ensure coordination across service lines, and build connection with the client’s full leadership team.
These teams also include engagement managers from each active service line, plus any associates working on the account. Ideally, many of these professionals will bring industry expertise to their roles—which will become more scalable the more narrowly a firm defines its niche.
This structure is especially effective when wrapped within an industry segmentation strategy. It reinforces the relevance of the firm’s advice, deepens relationships across client stakeholders, and increases the likelihood of multidisciplinary expansion.
To begin shifting to a client-centric firm, consider these five actions:
Remember, cross-selling isn’t a campaign—it’s an outcome. It’s a byproduct of aligning your firm to deliver value the way clients want to experience it. If your organizational chart makes sense internally but breaks down at the client level, it’s time to rethink it.
Delivering multidisciplinary services starts not with a sales push but with a design principle. First, organize around the client, not the service. From there, every system—roles, incentives, technology, and governance—must reinforce that model.
Ultimately, the firms that’ll thrive in this new era are those bold enough to reimagine how they operate—with the client at the center, not the margins.
