You can either register a Private Business Corporation (PBC). A PBC is a lot cheaper to register as it is government’s attempt to formalise the informal sector. It’s also specifically designed for small to medium businesses hence the attempt to reduce the price to accommodate smaller businesses who cannot afford the higher costs of registering a Pvt Ltd. Not only is a PBC cheaper to register, it’s also cheaper and easier to maintain. It has no annual returns and laws that govern it are pretty straight-forward.
