The Challenge

Millions of parking tickets are issued annually in the UK, and a significant percentage contain procedural errors that make them legally challengeable. However, most drivers either pay without questioning or struggle to draft effective appeal letters without expensive solicitor fees.

Production-Grade Platform

Build a SaaS platform capable of guiding users through the entire parking ticket appeal process

Encode Complex Law

Automate strategy detection across Protection of Freedoms Act, Traffic Management Act, and BPA Code of Practice

Frictionless UX

Convert visitors into paying customers with minimal drop-off and zero-friction onboarding

Near-Zero Cost

Launch at near-zero infrastructure cost, scaling expenses only as revenue grows

Full Compliance

Achieve GDPR, ASA advertising standards, and Trading Standards compliance from day one

Value-First Design

Show users their appeal strategies before requiring login or payment

What We Built

A complete, production-ready SaaS platform — from OCR-powered intake to professional document generation.

Intelligent Ticket Analysis Engine

OCR-powered intake using Google Vision API that extracts ticket data from a photo — PCN number, issuer, dates, contravention code, and penalty amount. Users upload a photo and have their ticket parsed in seconds.

Legal Strategy Detection System

A rules engine encoding 35 appeal strategies across private (18) and council (17) parking tickets. The system evaluates ticket data against a hierarchy of legal grounds, identifying every applicable strategy and ranking them by effectiveness. Includes 30+ operator profiles with enforcement history.

Professional Document Generation

Generates tailored, professionally formatted appeal letters in both DOCX and PDF formats. Each letter references specific legislation, includes evidence requirements, and follows the formal structure expected by operators and tribunals.

Frictionless Conversion Funnel

A 6-step flow optimised for conversion: Upload → Analysis → Questions → Processing → Preview → Download. No login required until users have seen their strategies — eliminating friction and ensuring value before payment.

Authentication & Security

Passwordless login via 6-digit magic codes + Google OAuth. JWT RS256 asymmetric encryption with 15-minute access tokens. Comprehensive security hardening: Helmet.js, rate limiting, CORS, input sanitisation, admin audit logging. Security rating: 9.5/10.

SEO & Content Infrastructure

24 SEO-optimised landing pages: 9 operator-specific guides, 10 city-specific guides, 6 location-type guides. Each page includes structured data (JSON-LD), meta tags, internal linking, and conversion-optimised CTAs — all server-rendered.
