Electronic Tax Invoicing in Nigeria
African countries lately have been opting to digitize their tax systems by imposing e-Invoicing or Electronic Tax Invoicing and Reporting. Electronic Tax Invoicing is a nascent Fintech category in the Pan-African region.
Nigeria is one of the countries and the country's tax authority/ regulator, FIRS (Federal Inland Revenue Service) has a transformative e-invoicing system, named FIRS Merchant Buyer Solution (FIRS MBS). In this documentation, DigiTax Nigeria API Hub, we shall simply refer to it as FIRS E-Invoicing System.
