New clients feel like the goal. Visible wins, something to point to, proof that BD is working. It’s understandable — but it’s also where a lot of BD energy gets lost.
Because while attention is pointed outward, existing client relationships tend to get left to drift. And that’s rarely a deliberate choice. It’s usually just what happens when there’s no plan pulling in the other direction.
What the data actually says
The O-Shaped Lawyer report, which looked at what clients actually want from their legal relationships, makes something clear that many firms still haven’t fully absorbed: clients don’t primarily want to be sold to. They want to feel known. They want their lawyers to understand their business, anticipate their needs, and be genuinely useful – not just technically excellent.
That matters for how lawyers approach BD. Because what clients describe as valuable – proactive thinking, lateral awareness, someone who connects dots across their business – isn’t something you can deliver if your attention is mostly pointed at people you haven’t met yet.
The most productive BD is often already in the room.
Why existing relationships get underinvested
Billing pressure means that time spent deepening a client relationship rarely has an obvious line on the timesheet. New-business activity, by contrast, has the feel of forward motion – pitches, introductions, events. It’s easier to point to.
There’s also a pattern that shows up regularly when working inside firms: lawyers assume that cross-selling or introducing a new service line belongs to someone more senior. That it’s not their place to look beyond their matter.
This costs firms a great deal of work that never gets asked for. And it costs lawyers an enormous amount of BD credit they could legitimately be building.
What you can actually do
Cross-selling has a reputation for being awkward — the transparent up-sell, the shoe-horned introduction. Done badly, that reputation is deserved. Done well, it looks nothing like that. It looks like curiosity.
The starting point is “what else is going on for them that we probably don’t know about?” — rather than “what else can we sell this client?”
A few practical ways to approach this:
- Reframe your client conversations. Regular contact with a client — even on a single matter — gives you licence to ask broader questions. What’s keeping them busy at the moment? Are there things coming down the line that they’re already thinking about? These aren’t sales questions. They’re relationship questions. And they’re the ones that surface need before it becomes a formal instruction.
- Learn the shape of the firm, not just your corner of it. Most lawyers know their own practice area well. Fewer have a working sense of what colleagues in other teams actually do, who they do it for, and what triggers a need for their advice. And that’s usually where the opportunity gets missed. Spending thirty minutes with a colleague in a different group — to understand, rather than to pitch — is genuinely useful BD preparation.
- Make notes, not just impressions. After a call or a coffee with a client contact, write down what came up. What were they worried about? What did they mention in passing? What surprised you? Over six months, those notes become a clear picture of where the relationship is, what’s changed, and where there might be an opening to do more. At appraisal time, they also become evidence.
- Use the access you already have. The friction that makes new-business BD feel hard — getting in the room, earning trust, demonstrating you understand their world — is already gone with existing clients. The question is whether that access is being used well.
The opportunity most lawyers are sitting on
Existing client relationships carry enormous untapped potential – not because firms aren’t capable of delivering more value, but because the system doesn’t naturally surface it. Lawyers are busy. Clients don’t always know to ask. The gap gets filled by inertia.
Lawyers who make it their business to close that gap — even incrementally — are doing exactly the kind of BD that gets noticed. It doesn’t require a large network or a high-profile event. It requires paying attention to the relationships already in front of you, staying curious about what lies beyond your matter, and being useful in ways that go slightly further than what was asked.
Pick one client relationship this month and ask yourself: do I actually know what else is going on for them? Start there.
