info_outlineIn this episode, hosts Peter Kang and Sei-Wook Kim dive into one of the most challenging but necessary decisions agency leaders face: when and how to let go of clients.

Peter and Sei-Wook break down the key factors to consider when evaluating your client roster, from strategic alignment and profitability to relationship quality and payment behavior.
They share real-world examples from their own experiences at Barrel, including how shifting their focus to Shopify-led projects meant parting ways with clients on other platforms.

Key Moments
1. Why “pruning” your client list is essential for sustainable growth.
2. How to assess strategic fit using your Ideal Client Profile (ICP).

3. Payment behavior is a leading indicator of respect, and risk.
4. Protect your team. Difficult clients can cause burnout and turnover.
5. Sometimes the best business decision is to fire a client.
6. Leaders must own the tough calls. Don’t push them down to the team.
7. Risk isn’t always financial, reputational and legal risks can be just as damaging.
