The business register is public, which means that the address you provide when registering your business will be visible to everyone: customers, business partners, debt collectors and anyone browsing online. If this is your home address, it will remain there permanently - it is virtually impossible to remove it from registers, invoices and search engines.
Then there is something few people think about when setting up a business: how official letters are served. A letter sent to the address on the register can be deemed served even if it sat uncollected in the letterbox. The time limit for a response is counted from the day the letter reached the address on the register, not from the day you read it. Being on holiday does not stop the clock. With a one-week deadline, that can be the difference between dealing with a matter in time and losing it.
Are you renting a flat? Then there's a third thing to consider: the landlord's consent to register your business at their address, and updating your details in KRS or CEIDG every time you move house. An address on Braniborska sorts out all these issues at once: your flat isn't listed in the register, we take care of collecting your mail, and when you move house, you don't need to update your details in KRS or CEIDG.
