The mandate doesn't sell itself — the urgency does. Start with the penalty calculator, then drill into the system, the market and the playbook.

The mandate, in one paragraph

Every VAT-registered invoice in Nigeria now needs an NRS stamp to be legal.

The Tax Administration Act (s.23) and Nigeria Tax Act (s.158) mandate fiscalisation of every B2B, B2G and B2C invoice through the NRS Merchant Buyer Solution (MBS) platform, using the UBL schema across the PEPPOL 4-corner network. Each invoice receives an IRN, a cryptographic stamp (CSID) and a verifiable QR. Without the stamp, the invoice is not legal — and the buyer cannot claim VAT input credit. Penalties stack: ₦1M day-one, ₦10k per day, ₦200k per non-compliant invoice, plus 100% denied input credit.
