ParseFlow — Bank Statement to Excel Converter
A self-built SaaS product that converts bank statement PDFs from 6 major UK banks into clean, formatted Excel spreadsheets — built end-to-end, from PDF parsing engine to billing.
The Problem
Accountants, bookkeepers and business owners regularly need to turn PDF bank statements into structured, usable spreadsheet data — a manual, repetitive, error-prone task with no reliable format-agnostic tool, since every bank exports statements differently.
Our Solution
Built ParseFlow from scratch as a full SaaS product: a Python backend that parses PDF statements from 6 UK banks (Revolut, Tide, Lloyds, Barclays, HSBC, NatWest) and outputs a styled Excel workbook with separate Transactions and Summary sheets, including net cash flow and running balances. Processing happens entirely in memory — files are never written to disk, so nothing persists beyond the conversion itself. User accounts and billing run on Firebase Authentication (with Google Sign-In) and Firestore, with a freemium tier plus a one-time premium tier for higher volume processing.
Results & Impact
A live, production SaaS product processing real bank statements end-to-end in under 10 seconds with 99.8% parsing accuracy, running on a self-service freemium-to-paid model with zero manual onboarding required.
