Automating Financial Statement Processing with Zero Document Retention
AI that extracts, structures, and then forgets — privacy-first financial data processing.
The business problem
A personal finance platform needed to give users insight into their spending by analysing bank statements. But financial documents are sensitive — the platform couldn’t afford to store source PDFs, and the extraction had to be accurate enough for users to trust. On top of that, the platform needed enterprise-grade security for a regulated environment.
What we delivered
- AI-powered extraction that reads uploaded bank statements and turns them into structured transaction data — automatically categorised, ready for analysis.
- Privacy-by-design architecture: source PDFs are permanently deleted the moment extraction completes. No document storage, no risk, no compliance burden.
- Intelligent deduplication that recognises when the same statement has been uploaded before — preventing duplicate transactions without needing to keep the original file.
- Enterprise-grade security across the entire platform — multi-factor authentication, role-based access, and complete audit trails.
