Most PEO CSAs auto-renew for 1-year terms unless you provide written notice 60–120 days before the renewal date. Missing the notice window means you're locked in for another full year at whatever the PEO's pricing is (often with material escalation).
What to negotiate:
- Notice period of 30 days, not 90+ — gives you optionality at renewal
- Right to terminate at renewal without penalty
- Clear date triggers — calendar date vs. anniversary date
- Email or written-form acceptance of notice — not certified mail only
