I'm about to share the exact script that transformed my clients' upsell success rates. But first, understand this:

You have 3 seconds to make your upsell offer feel natural.

The 3-Second Rule:

Acknowledge first purchase

Bridge naturally

Make relevant offer

Wrong way: "Would you like to add X?" Right way: "Since you're getting A, you'll probably want B to make it work better."

Results from a plumbing client:

Upsell acceptance: 23% to 64%

Average sale: +105%

Zero customer complaints

Remember: Make it feel like help, not selling.
