For resident companies operating local business, most clients will require a license under the Trade & Business Licensing Act. Some businesses without at least 60% Caymanian ownership or control will require a Local Companies (Control) Act License (LCCL).

Depending on the type of business, other licenses (such as medical and dental, planning, music and dancing, liquor licenses) may be required.

(Fixed fees can ensure that the debt collection process remains within budget and ensure that legal costs remain proportionate to the sum being recovered. In other situations, particularly where legal fees may be recoverable from the debtor, a time-spent basis may be more appropriate).
