Overview

TaxFlow turns HMRC's Making Tax Digital obligations into a workflow a non-accountant can complete. Bank feeds, receipt capture and quarterly submissions live in one place, styled with a light/dark design-token system so it stays calm under a lot of data.

The challenge

Tax software either overwhelms with accountant-grade complexity or oversimplifies until it's untrustworthy. The job was to make a regulated, high-stakes process feel legible without hiding what's really happening.

What went into it

  • Open-banking-style account linking, prototyped against a custom sandbox (see MockBank)
  • Receipt OCR moved from Tesseract.js to Google Cloud Vision for real-world accuracy
  • Supabase storage migration for documents and evidence
  • Light/dark theming built on an EightShapes design-token methodology
