Harvest tracks time and generates invoices. Hourglass does both — and adds real-time project profitability, team utilisation, resource planning and 8 built-in reports.
If you need a platform that connects time tracking to delivery management, invoicing, utilisation visibility and profitability insight — without stitching together multiple tools — Hourglass is purpose-built for professional services teams.
