Contract Benchmarking Tools Compared for Lawyers

Contract benchmarking tools compare each clause in a draft with terms from similar deals and show whether it is common, unusual or missing. For commercial contracts, our pick is Gavel Exec, which publishes its price and filters by jurisdiction, industry and company size. For mergers and acquisitions (M&A) and finance terms, look at Noetica, Bloomberg Law and Lexis.

This guide covers clause benchmarking: checking whether a contract's terms match what parties accept in comparable deals. It does not cover the benchmarking clause in outsourcing agreements, which is a price review term, or benchmarking of contract cycle times and other key performance indicators (KPIs).

Key takeaways

• Each tool draws on one or two kinds of data: pooled customer data, public company filings, your own signed agreements, benchmarks built by the vendor's lawyers or a clause database. Ask each vendor which one it uses.
• Gavel Exec benchmarks nondisclosure agreements (NDAs), master services agreements (MSAs), software-as-a-service (SaaS) agreements and other commercial contracts, and Spellbook, TermScout, LizzyAI, Law Insider and Sirion sell to the same commercial buyers. Noetica and Bloomberg Law Draft Analyzer draw on public filings and suit M&A, credit and securities work.
• Ivo Benchmarks compares a draft with your own past deals, which tells you what your organization has accepted before.
• Four of the ten vendors publish prices: Gavel Exec, TermScout, LizzyAI and Law Insider. LizzyAI and Law Insider do not say which plan includes their benchmark.
• A benchmark shows what is common for the filters you choose. Whether a term suits your client depends on the deal, so a lawyer reviews each result, whether it comes from artificial intelligence (AI) software or a published study.

What is contract clause benchmarking?

Contract clause benchmarking compares each provision in a contract with the terms found in similar agreements and tells you whether it falls within market norms. It answers the negotiator's question, "Is this term market?", one clause at a time.

A good result names the comparison set, marks the clause on-market, off-market or missing, and proposes language when the clause departs from the norm. Lawyers use it before sending a first draft, when the other side says a term is standard, and when they negotiate an unfamiliar contract type, industry or jurisdiction. Gavel's page on contract clause benchmarking walks through the workflow in Gavel Exec.

Where does "market standard" data come from?

Benchmark data comes from five main sources: data pooled from a vendor's customers, agreements that public companies file with the Securities and Exchange Commission (SEC), your own signed agreements, benchmarks that the vendor's lawyers build into the product, and published deal-point studies. The right column lists questions to ask any vendor.

Deal lawyers also benchmark by hand against published studies and standard forms: the American Bar Association (ABA) Private Target M&A Deal Points Study, the SRS Acquiom Deal Terms Study, National Venture Capital Association (NVCA) model documents, Common Paper and Bonterms standard agreements, and Thomson Reuters' Practical Law What's Market. These studies describe their own samples, which makes them a useful cross-check on software results.

How do the top contract benchmarking tools compare?

The ten tools fall into three groups. Gavel Exec, Spellbook, TermScout, LizzyAI, Law Insider and Sirion benchmark commercial contracts; Noetica, Bloomberg Law and Lexis focus on M&A and finance deal terms; Ivo compares a draft with your own signed agreements. The first table covers data, the second covers where each tool runs and what it costs.

Which tools benchmark commercial contracts like NDAs, MSAs and SaaS agreements?

Six tools here serve commercial contract work: Gavel Exec, Spellbook, TermScout, LizzyAI, Law Insider and Sirion. Gavel Exec and Spellbook name the contract types they cover, and the others describe coverage in general terms, so test each one on your own NDAs and MSAs before you buy.

Should you benchmark against the market or against your own past deals?

Use both when you can. A market benchmark tells you what other parties accept, which helps when the other side calls a term standard. An internal benchmark tells you what your organization has accepted before, which is the better guide once you have enough signed contracts of the same type.

Ivo Benchmarks: best for in-house teams with a long contract history

• Where it runs: Inside Ivo Review, in Word and Google Docs
• Benchmark source: Your previously executed agreements, filtered by counterparty type, industry and governing law
• Output: How often you accepted a provision, flags for clauses below your median, and drafts toward the 50th percentile
• Data needed: Ivo asks for at least 10 comparable contracts per category and says results get richer at 100 or more
• Price: Not published
• Source: Ivo Benchmarks post and Ivo vs. Gavel Exec

Other routes to an internal benchmark: Noetica can include a firm's private deal library, Spellbook plans a Siloed Data option, and in Gavel Exec you can generate a playbook from signed agreements and run it on new drafts. Boostdraft argues that teams should review against their own standards first. Our guide to contract playbook software compares the playbook tools.

How reliable are AI market benchmarks?

A benchmark is as reliable as the data behind it and the match between that data and your deal. Before you rely on a result, check the source, the number of comparable contracts, how recent they are, and whether the filters match your jurisdiction, industry, company size and side of the deal.

1. Test it on contracts you know. Run three agreements you have negotiated recently and see whether the tool flags the clauses you fought over.
2. Check the filters. Confirm the tool lets you match company size, industry and jurisdiction to your client's deal.
3. Cross-check contested terms. Compare the result with a published study or your own past deals before you cite it in a negotiation.
4. Read the data terms. If a tool pools customer contracts, confirm what it shares and get the client's consent where needed. The ABA's Formal Opinion 512 (July 29, 2024) covers confidentiality when lawyers use generative AI tools, and Model Rule 1.6 requires reasonable efforts to protect client information.

Frequently asked questions

What are contract benchmarking tools?

Contract benchmarking tools compare the clauses in a draft with terms from similar contracts and show how common each term is or whether it is missing. The main difference between tools is the comparison data: pooled customer data, public SEC filings, your own signed agreements or benchmarks built by the vendor's lawyers.

How do I know if a contract term is market standard?

Compare it with contracts that match your deal's type, jurisdiction, industry, company size and side. In Gavel Exec Market Benchmarking, choose the jurisdiction, industry and company size, upload the contract and read the result for each clause.

What is the difference between internal and external contract benchmarking?

External benchmarking compares a clause with what other parties accept, using a market dataset. Internal benchmarking compares it with your organization's own signed agreements, which is how Ivo Benchmarks works.

Is a benchmarking clause the same thing as contract benchmarking?

A benchmarking clause is a different thing: an outsourcing term that lets the customer compare the supplier's prices with market rates. Contract benchmarking checks a draft's terms against similar deals.

Does contract benchmarking software share my contracts with other customers?

That depends on the vendor's data model. Under Spellbook's Give to Get option, anonymous aggregate statistics join a shared pool in exchange for free access, and Spellbook says the data is completely anonymous; under Pay to Get, you keep your data out for an extra fee. Gavel Exec's benchmarks are built by Gavel's lawyers, and Gavel does not use customer documents to train AI models.

How much do contract benchmarking tools cost?

Gavel Exec costs $160 per user per month with 25 free queries, TermScout Certify costs $450 per user per month with a five-user minimum, and Law Insider's SimpleAI costs $1,790 per user per year, though Law Insider lists precedent benchmarking on its Enterprise plan. LizzyAI plans start at $40 per user per month, and the other vendors here quote through sales.
