There are only two models of running a business in the UAE:
Through a distributor. A foreign company delivers products without establishing an office in the UAE. This is quite a rare case, suitable only for certain products and services that are possible to provide on a rotational basis. As a rule, local clients will require a foreign provider to set up an office in the UAE. Besides, it is hard to develop a business without a physical presence on the market. This model of running a business in the UAE includes carrying out supplies through a local contractor that will act as a distributor.
Establishing a new UAE company, acquiring an existing business, and setting up a joint venture. This means you will run a local entity in the UAE. Usually, it will be a limited liability company.
