B2B and B2C E-Invoicing: Building a Transparent and Efficient Tax Ecosystem
Kenya has implemented mandatory e-invoicing through the Electronic Tax Invoice Management System (eTIMS), with the rollout starting on 1 December 2022 and full nationwide adoption scheduled for July 2026. This system is designed to streamline VAT and payroll tax reporting by requiring businesses to generate and transmit invoices electronically in real time.

While eTIMS represents a significant leap toward a digitally integrated tax ecosystem, its implementation has highlighted several challenges that governments and businesses continue to navigate.
According to The Star, businesses report system glitches and outages, difficulties integrating with existing ERP and accounting systems, and limited awareness or skills to navigate the platform.
EY pointed out that compliance pressures, real-time validation rules, and penalties create additional burdens, while non-compliance among informal suppliers complicates operations for otherwise compliant businesses. SMEs, in particular, struggle with adoption, highlighting the need for simplified, accessible solutions, as noted by KPMG.
Collectively, these challenges underscore that successful implementation depends not just on technology, but also on training, system reliability, and inclusive adoption strategies.
These issues are especially critical given Kenya’s VAT gap of 43%, which translates to an estimated annual revenue loss of US $1.6 billion.
So, what could be an alternative solution?
By deploying digital systems like traceCORE B2B and B2C E-Invoicing, the government could reduce the VAT gap to as low as 5%, unlocking an additional US $1.4 billion in revenue annually, according to our estimates based on open data. Beyond compliance, these solutions strengthen auditability, reduce fraud, and facilitate a more transparent and predictable tax environment, which are key factors in formalizing businesses and supporting inclusive economic growth.
