Harvest is built around invoicing. Hourglass is built around professional services delivery.
If your primary need is generating invoices from time entries, Harvest does that well. If you need resource planning, utilisation visibility, delivery management, and profitability insight — alongside billing export — Hourglass is purpose-built for the full picture.
