What is NRS e-invoicing?
NRS e-invoicing is Nigeria’s electronic invoicing framework that requires businesses to generate, validate, and transmit invoices through the National Revenue Service’s approved network. The goal is to improve tax compliance, increase transparency, and standardise invoice processing across businesses.
Is NRS e-invoicing mandatory?
Yes. Businesses that fall within the NRS implementation phases are required to comply with the e-invoicing mandate. Non-compliance may expose businesses to penalties and other regulatory consequences.
How does Duplo help with NRS e-invoicing compliance?
Duplo enables businesses to generate compliant e-invoices, submit them for validation, retrieve Invoice Reference Numbers (IRNs), and manage the entire invoicing process through a single platform. This helps reduce manual work while ensuring compliance with NRS requirements.
Who needs to comply with NRS e-invoicing?
NRS e-invoicing applies to VAT-registered businesses operating in Nigeria. The rollout is being implemented in phases, with different compliance timelines depending on business size and annual turnover.
Do I need to replace my accounting or ERP software?
No. Duplo is designed to work with your existing systems, making it easier to adopt NRS e-invoicing without overhauling your current finance operations.
How long does it take to get started with Duplo?
Implementation timelines vary depending on your business processes and existing systems. Our team works closely with you to ensure a smooth setup and a fast path to NRS compliance.
Can I integrate NRS e-invoicing into my existing systems via API?
Yes. Duplo’s APIs make it easy to embed NRS-compliant e-invoicing into your existing ERP, accounting software, or finance tools, helping you stay compliant with minimal disruption.
When does NRS e-invoicing become mandatory?
The implementation timeline depends on your taxpayer category and annual revenue. Businesses should begin preparing early to avoid disruptions and ensure they meet their compliance deadlines.
Can I continue using PDF invoices?
No. While you may still generate invoices in PDF format for customers, NRS compliance requires invoices to be created, validated, and transmitted in the approved structured format through the e-invoicing network.
What is an Invoice Reference Number (IRN)?
An Invoice Reference Number (IRN) is a unique identifier generated when an invoice is successfully validated through the NRS e-invoicing system. It serves as proof that the invoice has been processed and accepted by the network.
What happens if I don't comply with NRS e-invoicing requirements?
Failure to comply may result in regulatory penalties, tax compliance issues, delays in invoice processing, and challenges with VAT claims. Businesses that prepare early can avoid these risks and maintain uninterrupted operations.
