Can my free zone company do business with mainland Dubai clients?

A free zone licence does not by itself entitle you to do business onshore. For goods, products moving into the mainland must pass through an entity licensed onshore — typically a mainland distributor or commercial agent — with customs duty applying; alternatively, establish your own mainland branch or company for onshore sales. For services, it turns on where and how the work is performed; several free zones now offer dual-licensing arrangements with the Dubai authorities allowing defined onshore activity — check what your zone provides. Avoid simply invoicing mainland clients as if the restriction did not exist: that risks fines and weakens you in any client dispute. Full step-by-step guide: Mainland vs free zone company setup. A corporate lawyer familiar with your free zone can chart the compliant route.
