Getting started

What foreign businesses usually sort out first

  1. Choose how you will operate. A subsidiary, a branch, a representative office, or working through a local partner or distributor. The options and their conditions are set by the OHADA Uniform Act on commercial companies and national rules.
  2. Register the business. Company registration: the national company registry.
  3. Register for tax. Tax registration: Direcção Geral das Contribuições e Impostos (DGCI).
  4. Check investment rules and incentives. Some sectors have licensing, local-ownership or registration rules, and some investors qualify for incentives. Investment agency: the national investment agency.
  5. Permits for foreign staff. Work and residence permits: the national immigration authority.
  6. Banking and foreign exchange. Rules on accounts, moving money in and out and paying dividends abroad come from the central bank (Banque Centrale des Etats de l'Afrique de l'Ouest (BCEAO)) and the banks.
  7. Contracts and disputes. Agree the governing law, the courts or arbitration seat, and the language. Guinea-Bissau is not a party to the New York Convention – take advice on how a foreign judgment or award would be enforced.

A general checklist, not legal advice. What applies to you depends on your sector, structure and nationality.
