[Don Plumley]

In the standard t&c's for professional work we clearly state that late payment may be subject to interest at the highest allowable rates and/or stoppage of work. We also do not undertake work without a deposit.

A face to face meeting is in order. First, ask the question, "are you happy with our work?" The answer will usually be yes. Then state "Wonderful, glad you are happy. Then to continue enjoying the benefits of our work, we must be paid in a timely manner. The failure to pay has caused unreasonable burden and for us to continue to enjoy a professional relationship, this must cease."

Provide documentation to list billing dates and past due amounts plus reasonable interest expense. Explain that you will resume work when the past due balance is current, plus you will require a 50% deposit prior to undertaking future work.
