Evolucionar Consulting Ltd (EVC) delivers cutting-edge technology systems, process automation, and advisory services that help organisations optimise revenue generation, close compliance gaps, and drive sustainable growth.
Based on years of hands-on experience, EVC developed the IGR growth ARM concept — a structured three-pillar methodology that delivers not just an initial revenue spike, but continuous, compounding growth.
Immediate revenue uplift through targeted gap analysis, leakage detection, and rapid deployment of collection controls across all revenue streams.
Sustaining growth by continuously reviewing taxpayer behaviour, field feedback, and compliance trends to maintain a healthy, cooperative relationship between the authority and its taxpayers.
Real-time aggregation and oversight of all collectables across every revenue point, consolidated into an executive decision support dashboard with on-the-fly reporting.
"Throughout our journey, we have curated an impressive suite of technology systems that revolutionize revenue generation. By fostering idea-driven collections, efficient monitoring, and eradicating revenue leakage, we enable governments to optimize their Internally Generated Revenue significantly."
From our flagship Tax Management System to field mobile collection and forensic recovery — each product is engineered to address a specific challenge in the revenue value chain.
A robust, flexible, purpose-built platform that streamlines every aspect of the collection process and manages complex, rapidly evolving laws and policies. Bridges the tax gap through a componentized tax modernisation framework.
A purpose-built solution for generating tax documents at scale — receipts, credit notes, and tax clearance certificates. Supports bulk processing and batch printing, reducing turnaround times and enhancing operational efficiency.
A groundbreaking platform storing three years of tax payment history on a secure multi-functional card. Combines identity verification with real-time tax records, eliminating manual documentation through encrypted, role-based data access.
A state-of-the-art online platform consolidating all taxpayer interaction in one place. Enables online TCC access, self-assessment calculations, assessment reports, payment verification, document filing, and objections management — in real-time.
A comprehensive programme targeting hard-to-tax informal sector segments. Integrates advocacy, advisory, collections, and monitoring — including a Presumptive Taxation regime — to bring informal sector actors into the formal revenue net.
An innovative mobile payment solution designed for field collection. Functions both offline and online, enabling uninterrupted payment acceptance in low-coverage areas. Supports on-site biometric registration and RIN assignment.
A real-time aggregation platform covering all appointed collection agents across taxes, levies, and other sources. Integrates with third-party payment switches and includes a powerful Decision Support System for revenue reporting.
A comprehensive compliance and investigation platform covering company income tax, VAT, PAYE audit, tax fraud detection, gross tax evasion, and maritime fee computation by vessel type and gross tonnage.
A scalable enumeration platform capturing individuals, properties, businesses, signages, markets, and commercial assets linked to unique identifiers. Features geolocation tagging, compliance monitoring, API integration, and built-in analytics.
We combine technology, process expertise, and domain knowledge to address the full lifecycle of revenue and operational transformation — not just isolated parts of it.
Custom platforms, portals, and enterprise systems built to handle the scale, security, and compliance demands of revenue authorities and organisations.
We map AS-IS processes, design TO-BE workflows, and eliminate redundancy — delivering measurable efficiency gains before a single line of code is written.
RPA, intelligent document processing, and workflow orchestration that converts manual, error-prone operations into high-throughput automated pipelines.
End-to-end IGR strategy and technology — from tax base expansion and leakage detection to real-time collection monitoring and fiscal compliance analytics.
Certified PMOs and experienced delivery leads who keep complex, multi-stakeholder programmes on track, in scope, and within budget from inception to launch.
Data centre development, hybrid cloud architecture, mobile device management, and managed services for mission-critical operational workloads.
We embed with your teams to map existing AS-IS processes, identify pain points, and define the precise scope before proposing any technology.
Our specialists co-design the TO-BE process and system architecture — aligning technology choices with operational reality and compliance requirements.
We develop and automate in iterative sprints, testing at every stage with real users and real data so there are no surprises at go-live.
Post-deployment, we train all users, provide on-the-ground support during transition, and monitor performance to ensure the system delivers from day one.
We continuously tune systems using real operational data, applying the ARM framework to ensure revenue growth compounds over time rather than plateauing.
We measure success by revenue recovered, compliance rates improved, and processing time saved — not deliverables submitted.
Strategy through to managed services — one team, one accountability. No finger-pointing between vendors.
