I need a practical, streamlined software solution that helps my accounting practice stay on top of both client details and billable hours. The core modules should revolve around: • Client management – a clean CRM-style interface where I can store full contact information, record every interaction, and book upcoming appointments in an integrated calendar. • Time tracking – the ability to start and stop timers or enter manual entries that are automatically linked to the correct client, so I can easily pull accurate time-log reports. The first release only has to nail those essentials. Features such as automatic background tracking or fully customizable timesheets can remain optional for a later phase, so keep the architecture open for expansion. Key expectations • Modern, intuitive UI that works on desktop web browsers (mobile-responsive is a plus). • Secure user authentication and role-based access. • Simple dashboard or report that summarizes hours by client and by date range. • Export to CSV or PDF for both client records and time logs. • Well-structured code with clear documentation so future enhancements are straightforward. Tech stack is flexible—popular frameworks like Django, Laravel, .NET, or a lightweight JavaScript stack are all fine, as long as the final build is stable and maintainable. Please outline your proposed stack, timeline, and any relevant experience building similar management or CRM tools when you respond.
