In accountancy there seem to be far more businesses than good accountants and it is possible to take on unlimited clients (assuming you had the resources). So why wouldn’t you?
Because you want clients suited to YOUR business.
You want clients from the industries you know well and that will fit well into your processes. This will enable you to provide a better service with your enhanced knowledge.
You want the clients who fit you personally so that you enjoy working together. This will enable you to provide a better service that you enjoy.
You want the clients who can afford your fees. This will enable you to provide a better service as you won’t have to take on too many clients all vying for your time.
Keep an eye on your client list and your fees to ensure that you can provide high quality work.
