Transforming a Low-cost TIN validation Tool to a Million-Dollar Revenue Generator

Why validate Tax IDs (TIN)?

Every adult person or business has a Tax ID (TIN). Depending on the type and status of the TIN, a tax could be charged on the transaction between counterparties (buyer/seller). For businesses, not knowing if the counterparty is a business or not to calculate tax accordingly could mean paying out of your pocket and/or increase penalty risks.


Lookup is a Know Your Client (KYC) suite that verifies counterparties’ tax status by validating Tax ID Numbers (TINs). I lead a user-centric design approach with a modular architecture to simplify manual workflows and prepare the product for hyper-growth.


Today, Lookup validates over 1,500,000 TINs/mo. for our clients that prevents upwards to €100,000,000 loss of margin.

Manual Processes

Without automation, the validation process was slow and prone to errors.

Frequent Validation Errors

Errors due to minor formatting issues led to frustration and inefficiencies.

Lack of Strategic Insights

Tax managers expressed a need for high-level insights to support compliance monitoring.

Design Strategy: Prioritise ease-of-use and strategic insights to evolve the product from an Acquisition Tool to a robust Enterprise Solution

Initial Vision

To test Product-Market fit, initially Lookup was designed to be a low-cost offering to drive acquisition for other Fonoa products. The Design Strategy was therefore to focus on:

Aiding manual processes

Streamlining TINs upload, TIN format verification, etc. to showcase an intuitive tool, simplifying the technical aspect of an API-first product in sales demos.

Provide guidance and feedback

To minimise errors, enhance Tax Managers’ self-serve capability and operational efficiency.

Notable Solutions and Impacts

Balancing Feature Expansion without Feature Creep

As client interest grew, alongside rising feature requests and the addition of more robust product capabilities, I refined the product’s front-end architecture to centre around core user JTBDs—validating and extracting insights from TIN validations. This approach ensured essential features remained prominent while integrating complementary enhancements to improve workflow efficiency, avoiding feature creep and minimising cognitive overload.

Restructuring product architecture to improve workflow efficiency and shape new behaviours

Initially, the Validation page presented Single and Batch validators separately to align with existing workflows. However, user insights revealed that this mental model stemmed from limitations in legacy government databases or competitor systems based on data ingestion modes (single or batch of TINs).


I realised that users’ primary goal was to understand the TIN status and gather insights from the validation, rather than the act of validation itself. To address this, I iterated on the design by regrouping the Single and Batch Validator with their respective results into two pages: Validate (Single & Batch) and Records (Single & Batch). This restructuring aimed to streamline workflows and provide faster access to results.

Impact on User Workflow

Simplifying the validation flow removed an extra step between task and outcomes, providing the results directly, enhancing the user's decision-making capability and transforming their approach from tactical to strategic.

The users reported to be less concerned about how to validate TINs and more about the validation results, which impact their business directly.

A user-centric design strategy should always be adaptable and ready to evolve with the product.

By uncovering and addressing users’ Jobs To Be Done (JTBDs), you ensure the product meets essential user needs while leaving space for growth and innovation.

An adaptable design strategy starts by envisioning the ideal state or achieving product-market fit, then scales back to an MVP. This approach balances meeting current user needs and business goals with maintaining innovation and scalability for the future.

Fewer feature, more impacts

Adding a CSV guide with clear instructions and a downloadable template reduced errors from incorrect data formatting. Small, user-centric features can have a substantial impact on user experience and efficiency, demonstrating attention to detail that enhances both functionality and client satisfaction.
