Frequently Asked Questions

What project management tools do agencies use?: The most popular agency project management tools are Asana, Monday.com, and ClickUp for task management, and Productive or Kantata for full agency management (capacity planning + billing). Larger agencies often also use Harvest or Toggl Track specifically for time billing.
How do agencies bill clients for time?: Most agencies use Harvest (best for direct invoicing from tracked time), FreshBooks, or their agency management platform's built-in billing. The workflow is typically: track time against projects in a time tracking tool, generate client invoice from tracked hours, send via Stripe or bank transfer.
What's the best social media tool for agencies managing multiple clients?: Sprout Social and Hootsuite are the most used for larger agencies managing multiple client accounts — both support multi-account scheduling, client reporting, and team approval workflows. Buffer is better value for smaller agencies managing fewer accounts.
