i4nnova can help organizations move away from fragmented invoice processes and toward a more connected digital invoicing environment

In an exclusive interview with BusinessDay, Adebayo Akinwunmi, Director and Founding Partner at i4nnova, breaks down the technical architecture shielding their proprietary taXnovate platform. From end-to-end encryption protocols and real-time API input sanitization to multi-factor session authentication, Akinwunmi outlines how enterprise leaders can maintain total tax compliance without compromising data sovereignty or exposing critical financial networks to cyber threats, amongst other issues: Excerpts: How is i4nnova's integration layer helping large corporations bridge legacy ERP systems with the government's central validation portal? i4nnova's experience cuts across large enterprise and SMEs alike, delivering business and technology transformation projects. Our architecture and methodology incorporate high level of security and ensure seamless integration of multiple systems to the government`s central validation portal. We have carefully developed smart connectors to multiple enterprise resource planning applications such that our client's financial data is mapped appropriately and enabled to connect into the NRS portal without disrupting their business operation. Our approach is built around integrating the e-invoicing requirements into the business systems our clients are familiar with and already in use rather than having to replace their existing ERP or accounting packages. i4nnova is accredited to provide the end to end e-invoicing delivering System Integrator and Access Point Provider services that enable businesses using platforms such as SAP, Oracle, Microsoft Dynamics, Sage, Zoho, Odoo, QuickBooks, and custom-built solutions to participate in the NRS e-invoicing ecosystem. The objective is to make the transition as seamless as possible. Instead of forcing finance teams to abandon their existing invoicing processes, taXnovate by i4nnova provides the connection between the organization's existing environment and the broader government e-invoicing infrastructure. For businesses that do not require or support direct system integration, taXnovate also provides the flexibility to upload invoices manually. This approach allows i4nnova to support both large enterprises with complex ERP environments and businesses with simpler invoicing processes. What automated pre-validation features does i4nnova embed into its middleware? taXnovate is designed to support invoice validation before invoices are transmitted through the e-invoicing infrastructure. The purpose of this validation layer is to identify potential compliance issues before an invoice proceeds for government validation. taXnovate's validation capability focuses on ensuring that invoice information meets the applicable requirements before transmission, reducing the likelihood of avoidable invoice rejection. This includes supporting the validation and management of information required as part of the e-invoicing process, including the Authentication Seal. This helps save time and reduce the chances of rejection How has i4nnova architected its middleware to handle peak transaction spikes without latency? i4nnova's background and experience in enterprise ERP implementation and integration provides a robust foundation for our design and development efforts. taXnovate is scalable application designed to process and manage complex datasets and high volumes. taXnovate is a cloud hosted application and leverages the scale of global hosting infrastructure which allows us to efficiently handle high invoice volumes during the peak period without affecting system performance. How does i4nnova secure the transmission lifecycle and protect data privacy and audit trails? i4nnova provide a secure channel for businesses to participate in the government e-invoicing ecosystem. Data is transmitted through a secure encrypted channel with strict access controls and multi factor authentication. This ensures that data is protected, with valid SSL/TSL certificates and authentication that verifies user sessions for every request. In addition, our taXnovate API security validates and sanitizes all incoming API inputs to restrict the risk of attack. Data stored is also encrypted using advanced standard encryption algorithm. With immutable login we are able to write security logs to a secret read only storage location to make it difficult for records to be changed. Our systems record critical actions like log ins, permission changes, failed access attempts. Centralized monitoring and time stamping which uses synchronized clocks to ensure exact time accuracy for every system entry. What scalable or modular options does i4nnova offer mid-market businesses? Our taXnovate application is built with flexibility in mind. We offer modular and scalable features designed to grow transaction volumes and adapt to changing tax rules. It plugs directly into existing accounting or ERP software via pre-built API connector modules. Our system converts unstructured files into machine readable e-invoices using AI tools. This helps SMEs without ERP systems to stay compliant. taXnovate addresses all segments of the market leveraging a flexible pricing structure that takes into consideration the complexity of the business process and legacy system in use. We do have programs that enables SMEs get onboarded within hours depending on the ERP systems.Not every business needs a complex ERP integration project to comply with e-invoicing requirements. taXnovate can support businesses at different levels of digital maturity. For organizations with an existing ERP or accounting system, i4nnova can integrate their invoicing processes with taXnovate. This includes solutions such as SAP, Oracle, Microsoft Dynamics, Sage, Zoho, Odoo, QuickBooks, and custom-built systems. For businesses that do not require direct integration, taXnovate also supports manual invoice upload. This gives businesses two practical paths: Integrated e-invoicing: Connect the existing ERP or accounting solution to taXnovate. Manual e-invoicing:Upload invoices directly through taXnovate. This flexibility allows businesses to adopt e-invoicing without necessarily undertaking a major ERP replacement or transformation project. What are the most critical non-technical hurdles and how does i4nnova support change management? From our experience working with businesses on ERP and digital transformation projects, one of the biggest challenges is not necessarily the technology but having to change the way people work. Change management is embedded in our engagement model, training and knowledge transfer is a key success factor for any transformation project. Businesses need to understand how e-invoicing affects their existing finance, sales, procurement, billing, and approval processes. Common challenges include understanding the new requirements, identifying which existing processes need to change, preparing invoice data correctly, ensuring users understand the new workflow, and managing the transition without disrupting day-to-day operations. i4nnova approaches this as a business transformation exercise rather than simply a technical integration. Our ERP implementation experience allows us to work with organizations to understand their existing processes, identify the impact of e-invoicing, define the appropriate integration approach, support implementation, and help users transition to the new processes. The objective is to make e-invoicing part of the organization's normal business operations rather than treating it as a separate compliance activity. Beyond compliance, how can businesses leverage e-invoicing data for broader business value? E-invoicing should not be viewed purely as another regulatory requirement. When invoice information becomes structured and digitally available, businesses have an opportunity to improve the efficiency and visibility of their financial operations. taXnovate can help organizations move away from fragmented invoice processes and toward a more connected digital invoicing environment. This can support improvements such as reduced manual invoice processing, better invoice visibility, improved record keeping, easier tracking of invoice status, and more efficient finance operations. For organizations with integrated ERP environments, the opportunity becomes even greater because e-invoicing can form part of the broader digital finance process. How is i4nnova positioning its technology for Peppol, AfCFTA and cross-border digital trade? Nigeria's move toward standardized digital invoicing creates an important foundation for the wider digitization of financial transactions. The future of e-invoicing cannot be built around isolated national systems. Businesses increasingly operate across borders, and the growth of regional trade under the African Continental Free Trade Area will increase the importance of systems that can exchange structured business documents across different markets. Nigeria's MBS framework is particularly significant in this regard because it is built around international interoperability standards and the PEPPOL framework. The official MBS platform states that Nigeria's national e-invoicing infrastructure adopts PEPPOL-based interoperability and PINT specifications, with the framework being developed to support international invoice exchange.
