Convert Cross-Sell Page - Post-Purchase Lateral Offer

"The cross-sell isn't an upsell. The buyer's already mid-implementation on the first thing. The job here is to show them the next product they'll naturally need - not to extract more dollars while the wallet's open."

This skill builds the post-purchase cross-sell page: a related, lateral offer to an existing customer who's already past the OTO/downsell sequence.

When to Use

Trigger phrases: cross sell page, post-purchase upsell, related product page, convert cross-sell, /convert cross-sell <product>.

Use when:

• The customer has completed flagship + any immediate OTO/downsell sequence.
• A related (not duplicate, not upgrade) product genuinely fits their next step.
• The user wants to maximize LTV without breaking trust.

Cross-sells fire days-to-weeks after purchase, often from email - not seconds after checkout.

When NOT to Use

• Immediate post-checkout upgrade → /convert oto-page.
• OTO recovery → /convert downsell-page.
• Pre-purchase cold sales page → /convert sales-page.
• Thank-you page secondary stack → /convert thank-you-page.
• Auditing existing cross-sell → /convert audit.

Inputs

Required:

1. What they already own - the flagship + any OTO/downsell items purchased.
2. The cross-sell product - must be lateral (not the same thing they own at a higher tier).
3. Implementation timing - where the customer is in their journey (week 1? month 3? after the first result?). Cross-sell copy hinges on this.
4. One person + Nerve, post-purchase version - the new pain that emerged because of the first product's success. "You implemented [flagship]. Now you've got [new problem the cross-sell solves]."

Optional:

• Voice continuity from the flagship + earlier funnel.
• Existing customer Snapshot proof.
• out_path - defaults via build_report_path.
