Portugal Company House

Dear Everyone.
I am new in this group.
My query is :
1: In UK to open a business you have to be register in Company house (https://beta.companieshouse.gov.uk)

Is there any equivalent in Portugal who deal with Tax + Business documentation like company house ? If any body know the contact details would be great.
2: Also to close a business in Portugal is there any specific organisation who deal with everything like company house in UK.
