How Free Zone Cost Actually Works
The headline "licence from AED X" figure that free zones advertise is one component of four. To compare zones honestly, you need the full stack: the licence and registration fees (the advertised number, usually a zero-visa package); the visa block (establishment card, entry permit, medical, Emirates ID and residence visa fees for each visa, where cheap headline packages grow); the office component (most cheap packages include a shared flexi-desk or none); and renewal (the annual fee from year two).
Every free zone bundles these differently, which is why two "AED 5,000" packages can produce first-year totals thousands of dirhams apart. The only comparison that means anything is the all-in first-year cost at your visa count, next to the all-in renewal cost.
