Make sure you are comparing the right versions
Name the files clearly before running the comparison. Ambiguous names create review errors before the diff even starts.
Keep the baseline and revised copies untouched so the report always points back to a stable source pair.
Review the diff with a legal or commercial lens
Focus first on changed clauses, schedules, signatures, defined terms, and any page where formatting shifts could hide a meaningful change.
Use an annotated or watermarked review copy only after the version comparison is complete.
- check definitions and payment clauses first
- confirm page numbers and annexes still line up
- export the diff report for the review file
Decide what the recipient actually needs
Sometimes the next step is a marked-up review draft. Other times it is only a clean revised contract and an internal comparison record.
Choose the smallest distribution set that still supports the review process.
FAQ
Why compare contract versions locally?
It keeps draft agreements and negotiation history on-device during the comparison step, which is often preferable for confidentiality-sensitive work.
What should I review first in the diff?
Start with the clauses that change obligations, money, dates, termination rights, and defined terms, then check schedules and signature areas.
Should I add comments before or after the comparison?
Usually after. Compare the clean versions first, then create the review copy that needs comments or watermarks.
Does the comparison step upload the contracts?
No. The comparison runs locally in your browser.
