I need a compact tool that can create professional-looking bank statements for both salaried and self-employed users, ready for NBFC or fully digital approval flows. The generator must export directly to PDF and mirror the layout and detail you would expect from a real bank statement. Core functions required • Automatic income calculation from supplied transaction data • Expense categorisation into clear, editable buckets • Fully customisable templates so I can switch branding, colours and small layout tweaks without touching the code Beyond those essentials, the PDF should include a running balance, date-range filters and a concise summary section. I’m open to your preferred tech stack—Python, JavaScript, Java or another mainstream option—as long as the final code is clean, well-commented and makes use of stable, licence-friendly PDF libraries. Deliverables • Source code and any build scripts • Setup notes (local and server deployment) • Brief user guide showing where to modify templates and categories I will sign off the project once income/expense figures reconcile accurately, the PDF design matches approved samples, and template changes can be done without code edits. If you have previous financial document or statement generators, please include a quick demo link or screenshots with your bid.
