How do I keep my agency clients from leaving?

Put clients on a platform they use in their business. Before SaaS, once a client cancelled Facebook ads or a website project was finished, the client was gone. With Votel, the client's phone number, email, review automation, website and other systems live in their account, so they stay your client even after your marketing services or website work ends.

The more of their needs you cover (phone service, SMS, website and hosting, chat widget, social media management and so on), the more they rely on you and the longer they stay. Use as many of the platform's services as makes sense for your offer.

Balance that against your workload. Look for the minimum you can do that lets you set clients up quickly and easily, scales, and still has several pieces that keep clients sticky. Focusing on one niche and perfecting an offer for a specific solution also helps keep clients.
