How to Review a Customer's Redlines on Your Contract
When a customer sends back your contract full of changes, a simple process keeps you in control.
Key takeaways:
- Sort changes into cosmetic, commercial, and risk groups.
- Decide your must-haves before you respond.
- Check payment, renewal, termination, liability, indemnification, IP, data, service levels, and governing law.
- Use AI to compare, then verify and escalate high-stakes changes.
A redline can look intimidating. It is usually a handful of real issues in a lot of noise.

1. When the customer sends changes
You sent your standard customer contract. The customer returns it covered in tracked changes. What now?

Treat the redline as a list to sort, not an emergency.
2. Sort the changes into three groups

- Cosmetic: wording, typos, formatting. Usually quick to accept.
- Commercial: price, payment timing, term, renewal, scope.
- Risk: liability, indemnification, IP, data, termination. These deserve the most attention.
3. Decide your must-haves first
Before replying, decide what you cannot give up, such as a liability cap, payment terms, or ownership of your product. Everything else becomes negotiable. A short internal list keeps you consistent.
4. Nine clauses to check

Check each of these in the customer’s version against yours. Pay special attention to anything that changed liability, indemnity, or IP. For data terms see our AI vendor contract checklist.
5. Use AI to compare, then verify
AI can summarize what changed and group changes by type. It can miss a changed definition or a change buried in an exhibit, so confirm against the document. See AI contract review for small business and contract red flags.
6. When to bring in a lawyer
Large contract value, unusual liability or IP changes, or terms that would change how you operate are good reasons. See when to hire a lawyer.
