If you already have a business (single proprietorship) and it's properly registered, (DTI, BIR, LGU) say in City of Manila. You basically trade in general merchandise and you have sales agents and trucks go to areas to sell your wares.

You discover that in another area (say San Fernando , Pampanga), your items are in demand so much that you think of setting up a warehouse in the area so you can serve the demands of the Pampanga area better.

Kailangan pa ba mag register muli sa DTI for the warehouse? There is no walk in sales. Lahat delivery (either phoned in orders through the Manila office, or phoned in through the San Fernando warehouse). ?? How about mayor's permit? BIR?
