Cross-Sell Existing Customer

Eligible cross-sell account list with matched product and value hypothesis per account. CSM coordination completed. Cross-sell opportunities created as separate CRM records. Outcomes logged for fit matrix calibration.

Before you start

Existing customer base segmented by product owned and use case
Cross-sell product fit matrix documented
CSM and AE ownership clear per account
Customer record with current product mix and ACV
Usage data on existing products
Product fit matrix (which adjacent product fits which customer profile)

The steps

Identify cross-sell-eligible accounts — Filter customers who: (a) are at >60% activation on current product, (b) have usage signal indicating need for adjacent product, (c) are not in churn-risk status. Eligibility comes first — never cross-sell to a customer who is unhappy with the current product.
Match to a specific cross-sell product — For each eligible account, apply the fit matrix: which adjacent product solves a problem signaled by their usage? Avoid generic 'you might also like' — pick exactly one product with a clear evidence-backed reason. If no clean fit, deprioritize.
Draft a value hypothesis — Write a 2-sentence hypothesis: 'Based on [usage signal], they likely need [outcome]. The cross-sell product delivers that via [specific feature/integration].' Include a numeric estimate of value (e.g., '~10 hours/week saved') backed by similar customers.
Coordinate with the CSM — Before any sales outreach, share the hypothesis with the CSM owning the account. Ask: 'Is this the right time? Is there context I'm missing?' CSM has the relationship — never cross-sell over their head. If CSM says wait, wait.
Send the introduction message — Send from the AE (CC the CSM): reference a specific usage signal, propose the cross-sell product as a hypothesis (not a pitch), and offer a 20-minute exploration call. Subject: '[Company] — quick exploration on [outcome]'. Under 100 words.
Run the discovery and propose pricing — If they engage, run a focused discovery call (20-30 min). Confirm the hypothesis, identify decision criteria, and propose pricing aligned to the existing contract structure. Avoid renegotiating existing contract terms — keep the cross-sell additive and clean.
Log outcome and update opportunity — Create a new opportunity record (don't lump cross-sell into existing renewal). Track outcome: closed-won, lost (with reason), or deferred. Update the fit matrix with what worked or didn't for future cross-sells of similar accounts.

If it goes wrong

Cross-sell offered to a customer who's about to churn

Add a churn-risk gate to step 1. If health score is below threshold, exclude from cross-sell list. The fit matrix isn't enough — emotional state of the account matters.

CSM is bypassed and feels ambushed by sales outreach

Make CSM coordination a hard step — no message goes out without CSM sign-off. Track AE-CSM friction and resolve at manager level if it recurs.

Customer accepts cross-sell but barely uses the new product

Pre-qualify activation likelihood — if the cross-sell product requires a champion the customer doesn't have, the cross-sell is a future churn. Hold until the team is ready to adopt.
