I want a streamlined Transaction Manager that focuses exclusively on recording and tracking our sales transactions. Every sale should be logged the moment it happens, stored in a secure database, and be instantly retrievable through a clean, browser-based dashboard. Core workflow • A user enters or imports a sale. • The record is stored with essential data—at minimum the date, time, amount, and an internal reference ID. • I can search, filter, and sort by any of those fields and export the results to CSV or Excel. Deliverables - Database schema and migration scripts. - Responsive web interface for manual entry plus bulk upload (CSV). - Searchable list view with filters (date range, amount, ID). - One-click export to CSV/Excel. - Well-commented source code and a short README on setup. Tech stack is flexible; a typical LAMP, MERN, or Django/PostgreSQL setup is fine as long as it is open-source and easy to maintain. Please propose the stack you are most comfortable with and any off-the-shelf libraries you plan to integrate. Acceptance criteria 1. A new sale can be added, edited, or deleted from the UI. 2. List view returns correct results when filters are applied. 3. Exported file matches the on-screen data exactly. 4. Installation instructions let me deploy the system locally in under 30 minutes.
