Simplifying Complex and Data-heavy Workflows for Effortless Compliance
Compliance means each transaction (sale or purchase) must be reported to Tax Authorities to ensure accurate tax calculation and payment. For global businesses, monitoring complex real-time reporting, spotting anomalies, and resolving issues are vital for compliance.
As Lead Designer, I built a product that simplifies Tax Managers' workflows to report, track, troubleshoot transaction data to stay compliant but also gain strategic insights.
Today, e-Invoicing processes over 24 million transactions monthly, with the value of €26 million for our clients.
Resource limitations, evolving regulations, data quality, and error management are the key challenges to compliance.
Resource Constraints
Tax departments often lack the engineering support to query and gather data, implement integration with Tax authorities, and automatically handle errors — leading to dependency on external consultants which increases costs and reduces agility.
Complex and Constantly Changing Regulations
Varied formats, requirements, and technical specifications that update across multiple jurisdictions. Documentation in local languages requires translation and legal consultation, adding operational costs.
Data Quality Issues
Synchronisation challenges due to scattered, inconsistent, inaccurate or incomplete data across large volumes. Complex mapping between internal fields and tax authority schemas, plus incompatible technologies.
Cryptic Error Messages
Unclear guidelines, lack of timely updates, limited or no support from tax authorities, and inconsistent terminology make troubleshooting a constant struggle.

Understanding the Real Cost of Compliance
User interviews revealed how compliance demands drain resources, especially where tax compliance has low engineering priority. Added complexity risks adoption, underscoring the need for low-maintenance features. This insight shaped Fonoa Required Data, focusing on only essential data to streamline scoping and gathering.
The Power of Clear, Actionable Information
Client feedback highlighted how vague, cryptic error messages create friction. To address this, we designed the Error Management System to translate, standardise, and clarify errors, offering steps for resolution. This reduced support dependency and empowered users to troubleshoot independently.
