You can buy an already existing company in Andorra, however time and money saved is not substantial. Any non-resident wishing to create a new or buy an existing company will need to go through the process of foreign investment authorisation. Change of shareholders and name need to be processed through a notary similar when you set up a new company. Finally bank accounts need to be opened again and the commercial authorization has to be done again when domicile and activity code changes. Additionally the current owner may ask you for a price to sell the company and due dilligence for outstanding debt is highly recommended. We recommend a new set up.
