What does your actual renewal playbook look like?

I'm curious how different CS teams actually manage renewals in practice.

Do you have a formal renewal playbook or process? If so, what are the key milestones or signals you track?

For example:

• Customer goals / success criteria
• Product adoption
• ROI / value realization
• Executive engagement
• Champion / decision-maker relationships
• Renewal timing
• Expansion opportunities

And most importantly: which signals have actually proven useful in predicting whether an account will renew?

I'd love to hear what works in the real world—not what the textbook says.
