Outsourcing in practice

two men by the white board

“I am a sole practitioner and it was 5 years in when the business grew to a point where the workload became too much for me and my accounts assistant. It became really stressful keeping on top of all the deadlines and ensuring the work was delivered to my clients on time. I needed a qualified accountant to deliver the work but did not have the budget to hire one full time.”


“With the extra capacity our business has continued to grow. We spend less time moving figures around and more time ensuring our customers really understand the accounts to make a difference in their business.”

Diamond Outsourcing allowed me to delegate the accounts production work and take pressure off my team as and when needed. They complete work to a high standard and always meet our agreed timescales. They are super responsive, and I love that I can discuss technical tax matters to clarify my own understanding with a fellow chartered accountant.
