A contract negotiation workflow running on Word attachments and emails quickly gets disorganized. One reviewer sends a redline; the counterparty fires back a different version. Meanwhile, a colleague who missed the latest email adds comments to an older copy. Now, two versions are in circulation, and it becomes difficult to know who has seen what.
Contract redlining software is meant to prevent scenarios like this one by giving legal teams a shared place to review agreements, propose changes, collaborate, track versions, and, importantly, preserve a record of what changed during negotiation.
There’s more than one type of contract markup software, though. Some zero in on redlining alone. Others do redlining as part of a broader offering around contract lifecycles. Here’s a look at how contract redlining software works and what matters when you’re evaluating a tool.
What contract redlining software does
At its simplest, a contract redlining tool manages edits and collaboration throughout contract review and negotiation. That often means it lets users:
- Preserve negotiation history
- Track who made each edit
- Compare contract versions
- Suggest alternative wording
- Comment on provisions
- Add and remove contract language
- Accept or reject proposed changes
But the broader category of contract review tools comprises several types of products:
- Standard redlining tools: These tools are focused on collaborative contract review and markup.
- Contract lifecycle management platforms (CLMs): CLMs might include redlining as one part of the larger system for contract intake, approvals, execution, storage, obligations, and renewals.
- AI contract review tools: These tools analyze contracts against approved standards or a legal playbook, and they generate redlines for a human reviewer to evaluate.
There’s a lot of overlap among these products. A CLM might include AI-enabled redlining. Meanwhile, a specialized AI contract review tool might integrate with Word or a CLM you’re already using.
How contract redlining software works
The precise functionality of contract redlining software varies by tool, but at a high level, contracts are uploaded or shared in a collaborative review environment, letting all reviewers work from the same record.
Centralized editing and comments
Typically, users can suggest edits directly in a document, similar to using tracked changes in Word or suggested edits in Google Docs.
Contract redlining software often has the following controls:
- Comments
- Inline redlines
- Accept-or-reject controls
- Internal comments
- Counterparty-facing comments
- Alternative clause language
These controls enable a cleaner separation between the contract itself and the conversation happening around it. Importantly, you can have discussions without the other party seeing every detail. Legal, for example, might flag a limitation of liability clause and propose new language, leaving an internal comment that explains the commercial trade-off for the deal owner.
Version control
Version control is one of the key and most helpful differences between dedicated redlining software and the email attachment workflow.
With the software working as intended, users can tie each change to a particular reviewer and point in time. The systems can preserve past versions and show how the document changed between each round.
That way, users can quickly and easily determine which version is current, which redlines are unresolved, what the parties ultimately agreed to, and whether a counterparty restored previously removed language.
Permissions and collaboration
Role-based access determines who can see or edit different parts of the negotiation.
A legal reviewer, for instance, might have full editing rights while sales or procurement is able to comment on commercial issues. External counterparties, then, only get access to the version and comments intended for them.
AI-assisted first-pass review
Some contract redlining software injects AI into the workflow. AI contract redlining software solutions can compare clauses against a company’s playbook, and flag deviations from standard positions, identify missing provisions, and suggest alternative language.
AI functionality can be useful for legal teams with defined fallback positions and playbooks, as the software performs a first pass on a contract before an attorney starts the substantive review. AI review isn’t a replacement for human legal judgment, but it can make the contract review process more agile for lawyers.
Benefits of redlining software over Word and email
Microsoft Word remains an effective contract drafting tool, just as email remains an effective communication tool. But these two tools do not comprise a complete or efficient contract-review system.
Dedicated redlining software improves upon many of the drawbacks of the Word-plus-email system. Here’s how.
Faster negotiation cycles
When everyone works from the same contract record, no one wastes time tracking down the latest draft or repeating another reviewer’s edits. Over a large volume of recurring commercial agreements, the efficiency compounds.
Fewer version control problems
Centralized history makes version control mistakes easier to prevent. Imagine a reviewer accidentally working on an outdated version and missing that a counterparty had reintroduced language that was already resolved. The company could end up bound to terms it didn’t intend to agree to.
Better audit trails
The structured review system provided by redlining software preserves who proposed each change, when the change happened, and the final outcome. That provides a much cleaner negotiation record than can be gleaned from reconstructing decisions from email threads.
Easier delegation
If a company has documented fallback positions, it can delegate parts of first-pass reviews to redlining software. Because the software flags common issues in standard commercial contracts, it frees up time for experienced lawyers to focus on provisions that warrant considerable legal judgment.
Features to consider when selecting a redlining tool
Contract redlining tools can have attractive, robust feature sets, but it’s more important to choose the software that fits your team’s workflow—that is, the way your team reviews and negotiates agreements. Here are some of the most common features to consider.
Review and collaboration
This is a core function in contract redlining software. It usually includes:
- Inline redlining
- Comments
- Accept-or-reject changes
- Audit trails
- Version history
- Document comparison
Counterparties interact with this feature, too, so consider whether outside parties will have to create accounts or abandon their own workflows in order to collaborate with you.
Standardization and intelligence
Redlining tools don’t set contracting policy; they apply it. When your organization already knows its preferred positions and can provide them to an AI-powered redlining tool, it can automate big parts of the early review process.
Some useful features within this category include:
- Approved templates
- Contracting playbooks
- Fallback positions
- Clause libraries
- AI-generated suggestions
- Risk flagging and/or scoring
Security and access
Contract security is essential because these documents include sensitive business, pricing, security, and customer information. You can expect redlining tools to have security measures such as:
- Role-based permissions
- Single sign-on
- Encryption
- External-user access controls
- Audit logs
- Data retention policies and procedures
- AI data handling guardrails
- Policies on whether the tool uses customer data to train its AI models
The right combination of security features depends on your company’s broader compliance and security environment. For example, a company handling health data may need a vendor that will sign a HIPAA business associate agreement, while one with EU customers may need data residency options to meet GDPR transfer requirements.
Microsoft Word and workflow compatibility
Microsoft Word tends to still be the go-to software for legal document drafting, meaning that teams considering contract redlining software will likely need a tool that integrates with Word.
Alternatively, teams preferring a browser-based workflow will want to opt for a tool that operates right in their browser. And organizations with a long-standing CLM that they don’t plan to swap out should consider redlining tools that integrate with this tool, so as not to have a siloed review environment.
Best practices for teams running on redlining software
Since software won’t create a contract review strategy on its own, the teams that get the most value from redlining tools create clear standards the technology can refer to. Here’s how.
- Establish playbooks and fallback positions: Automated review works best when the redlining system has defined standards to compare against. Otherwise, the software may fall back to defaults or market standards, which may not represent your organization’s preferred positions.
- Preserve the reasoning behind important redlines: Write detailed comments so counterparties and future reviewers understand the reasoning behind changes and accepted or rejected positions.
- Move difficult issues out of comment threads: When discussions around one provision start being unproductive, comments and redlines may not be the right place to debate contract language. Take these complex conversations live.
- Keep permissions deliberate: Clear roles and permissions separate internal legal discussions from counterparty-facing comments, reducing the risk that sensitive information will end up where it shouldn’t be.

FAQs
How much does contract redlining software cost?
Pricing depends on factors like the type of software, number of users, level of functionality, and the robustness of AI features. When evaluating costs, teams should look beyond subscription price to factors like implementation effort, required integrations, user adoption, and how much review time the tool will cut.
What are the risks of using contract redlining software?
Risks depend on the strength of the software’s built-in security and access controls and how your team plans to use the tool. Automated suggestions can create accuracy risks, but only if users accept them without human legal review. Meanwhile, external collaboration features can spark security concerns when permissions are poorly configured. There’s also a version-control risk if only part of the organization uses the system while the rest keeps exchanging attachments through email.
Is contract redlining software the same as a CLM?
No. CLMs cover the greater contract lifecycle, from intake to execution, obligation tracking, and renewals. Redlining software, meanwhile, zooms in on review and negotiation. Some CLMs include redlining, and some redlining tools integrate with CLMs.
Does contract redlining software replace lawyers?
No. Redlining software automates parts of the review process, but lawyers still have to use their human judgment to craft new language, determine material risk, devise negotiation and business strategy, and weigh trade-offs.
