5 out of 5 · excellent training

Ian delivered an excellent training session on flexible fees for estate agents. The workshop was highly engaging and sparked several valuable ideas on how to adapt our business. Ian provided clear, practical strategies and showed us different ways to implement flexible fee models directly into our business.

5 out of 5 · Less Admin. More Growth. Real Results.

No longer am I sat for hours filling out spreadsheets, which is joyous! I think what we've been able to do is really get under the bonnet of our business using the Greenhouse OS system. We're expecting each of our business owners to significantly increase year-on-year their earnings which we're delighted about and part of that is because we've got the system up and cooking how we need it to work.

5 out of 5 · From “Good Enough” to Game-Changing Growth

Changing your CRM at any point, which I've done three times in the lifeline of our business, is a big deal and you want to make sure that you're moving with the right partner. The business benefits that you're going to get from it by moving from something which is usually out of the box and works "okay" to something which can be adaptable and can really help you grow your business is game-changing.

5 out of 5 · Better Clients. Stronger Commitment. Higher Completion.

Flexible Fees have improved conversion not only from creating that partnership with the client from day one saying "Yes, I want to use you and I believe in everything that you said and I'm really opting in for the saving," but also further down the line in the conversion of those clients being more committed to the process because it's created that partnership from both client to agent and they're more than likely to see the end result and complete.
