In Spain a limited company is called S.L. (Sociedad Limitada) and it is used to protects against creditor making claims against the personal capital of individual shareholders.
In order to set up your SL first you need to think about a name and then register it in the Registro Mercantil.
Then options are going to the Register office detailing the preferred name with at least two alternatives in case the name is already taken, and pay the registration fee aproximately 65 euros or do it online at RED DNSPROPIO.COM - Servidor .
The following days after your petition and payment you will receive official confirmation that your Business name is registered.
Then is just a matter of choose a bank and open a bank account in the name of the company (SL) with the minimum capital investment around 3,006 euros; once established your SL can use this money as working capital.
At this stage is reccomended going trough an attorney in order to set up the SL and the Business Deeds prior to the signing in the Notary office or seek to the CADE office (Centro de Apoyo al Desarrollo Empresarial) that helps citizen in all the step trough the draft of the Business deeds and signing at the notary office.
Once the Company deeds are done they will be review and sign by the Notary; Within few days the CIF number (Business id number) will be sent you by mail or email and you will be ready for business.
The last important advices for a new business are to draft a good Business plan and adequate Financing of the enterprises; Business plan has to point out the main aspects of the product or the service and the potencial customers.
