Timesheet Advanced closes the gap between hours worked and hours billed: timer and grid entry, approval workflows, rate cards by employee, role, and project, and invoicing that reflects exactly what was approved. For agencies, consultancies, and law-style professional services where unbilled or misbilled hours are the silent margin leak. Planned features include start/stop timers and weekly grid entry with reminders for missing days, manager approval workflows with rejection reasons, multi-level rate cards with overtime multipliers, budget burn tracking with threshold alerts to project managers, billable-versus-non-billable analytics, utilization dashboards per employee and team, and invoice generation from approved time with write-up/write-down control. This app is currently in development on the ECOSIRE build pipeline. It will ship first for Odoo 17, 18, and 19 simultaneously, with an ERPNext port following on the v15/v16 track — the same triple-version coverage as every live ECOSIRE app. One-time license, free updates within your major version.
