CASE STUDY

Turning a £12m client portfolio into a more predictable growth engine

From strong relationships and reactive account management to clearer ownership, better retention and more deliberate growth.

THE SITUATION

Good client relationships weren't the problem

The agency had built a substantional client portfolio whorth approximately £12m in annual revenue.

There were strong relationships, talented teams and plenty of client activity.

But, commercial performance relied too heavily on experience, instinct and individual relationships.

  • Client health was unclear
  • Growth was inconsistent
  • Senior dependancy was high
THE COMMERCIAL CHALLENGE

To turn a successful but reactive existing-client operation into a more controlled, deliberate focus with less reliance on individual relationships

01

See risk earlier

Client health needed more than just a feeling.

02

Create ownership

Commercial ownership couldn't default upwards.

03

Find the growth

Opportunity needed to be surfaced and become action.

WHAT CHANGED

Client health

A clearer view of relationship strength, commercial risk, opportunity and future confidence.

Account ownership

Clearer responsibility for protecting and developing each client, rather than relying on senior leadership.

Portfolio focus

Different clients received different levels of attention, from high growth opportunities to maintenance or conscious de-prioritisation.

Commercial conversations

Teams moved from reactive delivery discussions to more useful conversations about the client's priorities, problems and future needs.

Leadership cadence

A regular rhythm for reviewing the portfolio, surfacing risk earlier and deciding where senior attention would have the greatest commercial value.

THE IMPACT

Over the following 12months:

75% to 90%

Client retention

80% to 70%

Dependancy on largest account

+80%

Growth on a major strategic account


Existing-client growth became something that the business could manage deliberately rather than simply hope it would happen.

THE IMPORTANT BIT

Good relationships aren't the same thing as commercial control

There was no magic framework or dramatic intervention. The improvement came from putting relatively simple commercial disciplines around work the agency was already doing: understanding client health properly, creating clearer ownership, identifying where growth was genuinely possible, having better conversations and reviewing the portfolio consistently.
