Cross-sell

Selling an existing client a different, complementary service alongside what they already buy - widening the relationship.

For example, an SEO client is happy, so the agency cross-sells a paid-ads service that builds on the same goals. The client gets a more joined-up solution, and the agency deepens an account it already understands.

Why it matters to your firm: cross-selling grows accounts and makes them stickier - a client buying two services is far less likely to churn than one buying a single thing. Like upselling, it lifts net revenue retention without the cost of finding a new client.
