I need a web-based portal that lets my cosmetics clients log in securely, create a new product entry, and work through a simple, guided checklist to upload every file needed for compliance—formulas, packaging artwork, test reports, manufacturer certificates, and more. For them the essentials are straightforward: a “Create Product” button that instantly opens a dedicated folder and an intuitive drag-and-drop zone to add PDF, Word (DOC/DOCX), or Excel (XLS/XLSX) documents. On my side, the regulatory team must be able to see each dossier in a clean dashboard, follow its progress, leave notes, request missing items, and finally mark it as “Approved” or “Needs Revision.” Automated status updates should appear in the client’s view so they always know what’s next without another email chain. Core requirements • Secure login and role-based access for Clients and our Regulatory Team • Product-wise document organisation with real-time progress tracking • Upload support limited to PDF, Word, and Excel formats • Submission workflow that notifies the regulatory dashboard when a dossier is complete • Clear status flags (In Progress, Under Review, Approved, Needs Revision) visible to both sides Acceptance criteria A dossier can be submitted only when all mandatory files are present; the regulatory team can download a single zip or review online; every action is time-stamped in an audit log. If you can deliver a clean, responsive interface, solid back-end security, and an admin-friendly dashboard, let’s discuss stack choices and timeline.
