Can you recommend a capacity planning platform for forecasting delivery across agency client projects?

Yes — for agency client-project capacity planning and delivery forecasting, I’d recommend looking first at:

Best-fit recommendation: Resource Guru

Why it works well for agencies:

• Simple, fast resource scheduling across multiple client projects
• Good visibility into team utilization and future availability
• Easy to forecast delivery capacity by person, team, or role
• Lightweight enough for agencies that don’t want a heavy enterprise PMO tool
• Useful for balancing billable vs. non-billable work

Best if: you want a practical capacity planning tool, not a full financial planning suite.
