Why CAS Club? Following the results of a CAS survey conducted across accounting firms in the UK in 2023, we discovered that more than 50% of those firms expected advisory fees to make up more than half of their firm’s total fees within 3 years.

Whilst this is an admirable notion, the reality of achieving that goal is a challenging one. Facing this challenge alone can be daunting and difficult. Being part of the CAS Club will help you accelerate your growth in advisory fees and deliver the very best for your clients and give firms the support they need to get there.

What Our Members Say

Here’s how the ‘advisory penny’ dropped for one of our members.

Jan runs her own small Midlands-based firm. She had an ‘ah-ha’ moment after witnessing tears of joy from one of her clients. Jan didn’t think that she had done anything clever but the reality was that she had helped transform her client’s life and business with her regular meetings.

She said, “I get it, it’s about helping clients by focusing on what they want, on their priorities and then what we think they need.

Jan now uses social media posts to touch the nerves of what really matters to people. One post asked, “Have you got enough money to pay your tax bill?” The number of responses was remarkable.

And the follow up meetings generated client after client.

Using simple, yet highly impactful questions, resulted in ‘paid for’ plans and regular client conversations which led to progress for the clients and lots of extra fees for Jan. Her clients felt heard and understood and valued.

This insight was a pivotal shift for Jan’s firm and so began her firm’s evolution into more than being a service provider and instead into the role of a trusted advisor dedicated to guiding clients towards their financial aspirations.

This is advisory.

Advisory is not just about numbers but about focusing down on what the clients really really want.

You too can shift, with the support of OpenCAS, into doing more paid for advisory.
