I operate a chauffeur fleet and need a web-based payroll platform that turns our raw shift logs into accurate, compliant pay. The system must handle salary calculation, overtime tracking, full tax computation and produce downloadable payslips without manual spreadsheets. Because our cars transmit GPS data, the payroll engine has to read attendance and location stamps so wages reflect the exact time each driver is on duty, waiting or travelling. I picture a responsive browser app that an accountant can open on a laptop while drivers can still check their hours on a phone. Core screens will let me: • import or API-pull daily attendance and location feeds, • review and edit shifts, • run a pay-period calculation, • generate PDF/CSV payslips and summary reports. Role-based access (Admin, Accountant, Driver) and a clean dashboard are essential. You are free to pick the web tech stack—Laravel, Node, Django, React, or something comparable—as long as it is well-documented and can be deployed on a standard cloud host. Deliverables 1. Full source code with database schema and migration scripts 2. Deployed demo on a test URL for acceptance 3. Configuration panel for tax, overtime and allowance rules 4. User and installation guide (PDF/Markdown) Acceptance criteria • When supplied with our sample data, the system must produce a payslip that matches the control sheet within 1 % • All pages load correctly on the latest Chrome desktop and mobile browsers • Code passes a basic OWASP Top-10 security check If you have built payroll or fleet-related systems before, please include a quick note and any relevant links in your bid.
