Seamlessly Sync Your Sage ERP with FIRS Merchant Buyer Solution (FIRSMBS)
The Federal Inland Revenue Service (FIRS) of Nigeria has launched the Merchant Buyer Solution (MBS), a robust e-invoicing system aimed at improving transparency, combating tax evasion, and digitizing financial transactions.
The FIRS platform ensures that all invoices are authenticated and pre-validated by FIRS before being shared with buyers. This compliance framework impacts all registered businesses and VAT-liable entities operating in Nigeria.
To simplify this regulatory shift, Greytrix Middle East offers a seamlessly integrated e-invoicing solution for Sage ERP systems (Sage X3, Sage 300, Sage 200 Evolution), enabling Nigerian businesses to comply with FIRS requirements effortlessly.
