7 Best Contract Review Services

Contract review services are law firms, talent networks and attorney marketplaces that review, redline, negotiate and draft commercial agreements. This guide ranks 7 providers for US software companies. Arceus Legal ranks #1 for flat per-document pricing published before work starts, licensed attorneys on every engagement and an 8 hour review turnaround promise.

Arceus Legal publishes this site and is ranked #1 below. We've aimed to describe every other pick fairly and tell you when one of them fits better.

Key Takeaways

• Arceus Legal, General Legal and Crosby all price commercial contract work per document, with licensed attorneys on the work.
• Axiom, ContractsCounsel and UpCounsel connect you with lawyers; none of the three is a law firm, by their own statements.
• Get negotiation pricing in writing before you sign up, because negotiation drives most quarter-end surprises.
• Ask every provider what happens when a turnaround promise slips, and get the answer in writing.

How We Evaluated These Contract Review Services

We scored each provider on five criteria. They are who does and approves the work, published prices, stated turnaround, contract coverage and minimum commitment. Attorney involvement and price visibility carried the most weight, because they decide cost and risk on every deal.

Provider details, pricing and sources in this guide were last updated on September 28, 2026. Where a provider doesn't publish a figure, we say so or cite a named third-party source.

Many buyers also weigh Cooley, Gunderson Dettmer and Wilson Sonsini, full-service firms built for financings, M&A and IPOs. None of the three publishes flat per-document prices for contract review. Arceus Legal handles commercial contracts at a flat price set before work starts, with an 8 hour turnaround or the review is free.

What Contract Review Services Do for a Growing Software Company

A contract review service reads an agreement, flags terms that shift risk onto you and returns a redline with suggested edits. Most providers also negotiate with the counterparty and draft new agreements from scratch.

Arceus Legal is a US law firm whose licensed attorneys work alongside AI agents on its CounselOS platform. Arceus Legal reviews, redlines, negotiates and drafts commercial contracts for B2B software companies at flat per-document prices.

Other models include talent networks that place lawyers inside your team and marketplaces where independent attorneys bid on your project.

How to Choose a Contract Review Service

Choose a contract review service by matching its pricing model and turnaround to your monthly contract volume. A company signing five contracts a quarter needs different coverage from one signing 60 a month. Use these vetting questions and the tell behind each.

• Who approves the final redline? A clear answer names a licensed attorney and the states where that attorney is admitted.
• How is negotiation priced? A provider that can't quote negotiation up front will likely bill it hourly.
• What happens when the deadline slips? Look for a written remedy, such as a refund or a free review.
• Who supervises the lawyer? Some networks expect your in-house team to supervise, which leaves a founder without a GC exposed.
• Do they keep your fallback positions? Playbook memory stops you from renegotiating the same clause twice.

Month to month, work at Arceus Legal follows a set pattern. You send a contract through Slack or email, AI prepares the first pass, and a licensed attorney approves the review.

Arceus Legal remembers each customer's positions, so your second MSA is reviewed against the positions you took in your first. Your legal preferences, risk tolerance and business goals are accounted for on every deal.

Firms that bill by the hour appear in our list of the 7 best business contract lawyers.

The 7 Best Contract Review Services, Ranked

1. Arceus Legal: Best for B2B Software Companies With Steady Contract Volume

Arceus Legal is a law firm that pairs AI agents with licensed, US-barred attorneys to review commercial contracts at flat, published prices. Arceus Legal's homepage promises an 8 hour turnaround on contract reviews, or the review is free.

Arceus Legal's pricing page lists $250 for an NDA or order form review and $500 to $1,000 for a standard 1 to 24 page contract. Complex contracts of 25 pages or more start at $1,000, and negotiation runs from $500. The Custom plan adds faster SLAs, urgent request handling and extended-hours coverage.

Arceus Legal states that its licensed, US-barred attorneys handle every engagement. On CounselOS, AI does the preparation and a licensed attorney approves every output. Picture a 40-person SaaS company with a 38-page enterprise MSA due before quarter-end: the price is known before the work starts.

Arceus Legal's backers include Greycroft, Craft Ventures, South Park Commons and Conviction, per its homepage.

• Flat per-document pricing, published on the pricing page
• Covers NDAs, MSAs, SOWs, DPAs, BAAs, vendor and customer contracts, renewals, Terms of Service and Privacy Policies
• No annual commitment on the On-Demand plan
• Custom annual plan with a named attorney, custom playbooks and reserved quarter-end capacity
• CounselOS includes a contract vault, e-signature and renewals
• Slack and email intake, HubSpot, Salesforce and Gmail connections, and close-date prediction

Pricing: from $250 per NDA or order form review; drafting is custom-priced.

Who should choose Arceus Legal:

• Seed through Series D software companies without in-house counsel
• Solo GCs who need overflow capacity at quarter-end
• Finance leads who want legal spend fixed per document

Limitations: Arceus Legal focuses on commercial contracts and policies, so choose a different firm for litigation, fundraising or M&A counsel. Custom plan rates aren't published, so you'll need a quote for annual pricing.

2. General Legal: Best for Startups Wanting Contracts Plus Broader Corporate Work

General Legal is an AI-native law firm offering flat-fee contract review, negotiation and drafting alongside a wide corporate practice. The firm says it "hires only highly-qualified, US barred attorneys."

General Legal publishes one of the clearest price menus in the category. Its pricing page lists $250 for simple reviews up to 3 pages and $500 for 3 to 25 page reviews with one revision round. Full negotiation costs $1,000 with unlimited turns, and drafting costs $2,000 per foundational document.

General Legal's homepage lists eight practice areas, from technology transactions and data privacy to tax and emerging companies. Named clients include Cartesia, BetterUp and Reducto, and its leaders include former partners from Fenwick, Cooley and Perkins Coie.

• Unlimited negotiation turns in one $1,000 fee
• Employment, tax, VC and blockchain work on published price menus

Pricing: from $250 per simple contract review.

• Founders who want one firm for contracts, equity and hiring documents
• Teams with long negotiations that benefit from unlimited turns

Limitations: Arceus Legal's review is free if it misses its 8 hour turnaround. By contrast, General Legal doesn't publish a remedy for a missed turnaround on its website (last updated September 28, 2026). Its standard review includes one revision round, so further turns need the negotiation package.

General Legal vs Arceus Legal

Arceus Legal's review is free if it misses its 8 hour turnaround, per its homepage. On its website, General Legal publishes no remedy for a missed turnaround (last updated September 28, 2026). On practice breadth and bundled negotiation turns, General Legal comes out ahead.

3. Crosby: Best for High-Velocity Startups Chasing Sub-Hour Reviews

Crosby is an agentic law firm that uses AI agents for first-pass review and licensed attorneys for verification. Crosby's homepage says contracts are reviewed "in under an hour."

Crosby's site says more than 50 licensed attorneys review all work, and the firm carries malpractice insurance as a registered professional limited liability company. Forbes reported in March 2026 that Crosby charges $250 to $1,000 per contract.

Crosby's homepage lists "Custom Memory: Secure, persistent knowledge tailored to your business." Forbes also reports that CEO Ryan Daniels, a former in-house counsel, cofounded the firm in September 2024.

• Sub-hour review claim on the homepage
• Per-document pricing with one charge regardless of review frequency, per Forbes
• Focus on NDAs, MSAs and DPAs
• Series B of $60 million led by Index Ventures and Lux Capital, announced March 31, 2026, per Forbes

Pricing: custom quote; $250 to $1,000 per contract, per Forbes, March 2026.

Who should choose Crosby:

• AI startups signing large NDA volumes that need answers within the hour
• Teams that value a large attorney bench over a published menu

Limitations: Crosby doesn't publish a price list on its site, so you'll need a quote. The site doesn't state jurisdictions covered.

Crosby vs Arceus Legal

Arceus Legal publishes its prices on its pricing page, and its Custom plan includes a named attorney. Crosby and Arceus Legal both pair AI agents with licensed attorneys and charge per document. Crosby advertises reviews in under an hour, while Arceus Legal attaches a free-review remedy to its turnaround.

4. Axiom: Best for In-House Teams Needing Embedded Contracts Lawyers

Axiom is an alternative legal services provider that places vetted lawyers inside corporate legal teams on secondment, project or on-demand terms. Axiom's homepage cites a network of more than 14,000 legal professionals.

Axiom's contract review page describes four steps: a consultation, a curated shortlist, interviews and then work. Axiom says you can engage a contract review lawyer within a matter of days. Its lawyers average more than 15 years of experience, per the same page.

Axiom's FAQ says Axiom doesn't operate as a law firm or give legal advice. The client's legal team supervises the Axiom lawyer's work, so the model works best when a GC already sets positions.

• Full-time, part-time or on-demand engagements, remote or on site
• Offices in the US, Canada, the UK, Australia, Hong Kong and Singapore
• Covers NDAs, licensing, purchase and sale, and lease agreements
• Lawyers working in more than 30 languages, per the contract review page
• Recruitment options, including interim-to-permanent and permanent placement
• Homepage claims savings of up to 50% against leading law firms

Pricing: custom pricing by engagement.

• Enterprise legal teams covering a parental leave or hiring gap
• GCs who want a dedicated contracts lawyer working inside their tools

Limitations: Axiom expects your legal team to supervise its lawyers, which doesn't suit a founder without counsel. Axiom publishes no per-contract prices.

Axiom vs Arceus Legal

Axiom supplies a lawyer for your team to direct. Arceus Legal takes a contract and returns completed work at a set price.

5. Outside GC: Best for Companies Wanting a Former GC on Call

Outside GC is a Boston-based law firm whose attorneys are former general counsel and senior in-house lawyers. Its homepage promises "direct access to senior attorneys, no associates, no learning curve."

Outside GC's commercial and procurement practice covers services agreements, vendor contracts, SOWs and order forms, distribution and supply contracts. The same team builds templates, negotiation playbooks and internal training, and handles renewals, amendments and terminations.

Outside GC lists 11 practice areas, including AI and cybersecurity, technology transactions and employment. That breadth suits a company that needs one relationship across many legal questions. Its office sits at 501 Boylston Street in Boston.

• Former GCs and senior in-house counsel doing the work, with no associates
• Template development and negotiation playbooks for your sales team
• Coverage of public sector prime contracts, subcontracts and teaming agreements
• Clients from startups to Fortune 500 companies, per the firm

Pricing: custom pricing; rates aren't published.

• Companies that want strategic judgment from a former GC
• Government contractors handling prime and subcontract agreements
• Mid-market companies that want playbooks built for their sales team

Limitations: Outside GC doesn't publish per-contract prices or turnaround times. You'll need a scoping call before you know your cost.

Outside GC vs Arceus Legal

Outside GC sells an ongoing senior-counsel relationship across many practice areas. Arceus Legal sells priced, per-document contract work with a stated review turnaround. Startups weighing the relationship model should see our guide to the best outside general counsel providers for startups.

6. ContractsCounsel: Best for One-Off Reviews With Competing Flat-Fee Bids

ContractsCounsel is a marketplace where independent contract lawyers bid flat fees on your project. Its homepage says you'll receive multiple proposals "in less than 24 hours."

ContractsCounsel's fee page says half of the last 500 contract review bids fell between $400 and $800. Clients pay through the platform, fund 50% upfront and add a 3% transaction fee.

ContractsCounsel says it doesn't operate as a law firm or give legal advice. The lawyer you hire does the work, and the platform says every lawyer goes through testing and vetting.

A design agency with one vendor contract a year fits this model well. Posting is free, and competing bids show the going rate for that document.

• Free project posting and payment through the platform
• Multiple flat-fee bids to compare side by side
• 4.8 out of 5 average rating shown on the homepage
• Lawyers across many industries and contract types

Pricing: flat bids; half of recent review bids ran $400 to $800, plus a 3% fee.

Who should choose ContractsCounsel:

• Small businesses reviewing one or two contracts a year
• Buyers who want to compare lawyers on price before hiring

Limitations: Quality, speed and playbook consistency depend on which lawyer wins each bid. Expect to brief each new lawyer on your fallback positions.

ContractsCounsel vs Arceus Legal

ContractsCounsel suits occasional buyers who want to shop each project. Arceus Legal suits repeat buyers who want one firm and one price list. ContractsCounsel also works as a price check against any firm's quote.

7. UpCounsel: Best for Hiring a Freelance Business Attorney by Project

UpCounsel is an online marketplace that matches businesses with independent attorneys. UpCounsel's homepage says attorneys send custom proposals within hours and average 14 years of experience.

UpCounsel's pricing page says work can be billed as a fixed fee or hourly. It lists sample commercial contract rates of $240 to $600 per hour and general counsel rates of $200 to $500. Attorneys invoice through UpCounsel on completion, though some request part of the fee upfront.

UpCounsel's how it works page says UpCounsel doesn't operate as a law firm or provide legal services. The attorney you hire does the legal work.

• Algorithmic matching to attorneys by practice area
• Free proposals, plus document storage and e-signature tools
• Sample fixed fees, such as $600 to $800 for trademarks
• Coverage across formation, IP, employment and securities work
• Claims more than 10,000 businesses as users, per its homepage

Pricing: fixed or hourly; commercial contracts from $240 per hour.

Who should choose UpCounsel:

• Businesses that want one freelance attorney across several legal areas
• Owners comfortable negotiating scope and fee per project
• Companies that need a trademark filing alongside a contract review

Limitations: Hourly billing makes the final cost hard to predict, and turnaround depends on the attorney. Check each profile's project history before hiring.

UpCounsel vs Arceus Legal

UpCounsel gives you a wide choice of independent attorneys across practice areas. Arceus Legal gives you fixed contract prices from one firm. UpCounsel also covers filings that Arceus Legal doesn't handle, such as trademarks.

Contract Review and Risk Flagging

Risk flagging means marking every clause that moves liability, payment or data risk onto your company. Common flags include uncapped indemnities, auto-renewals and one-sided termination rights.

A good review ranks flags by severity so a founder can decide in minutes. Arceus Legal runs this first pass with AI agents, and a licensed attorney confirms every flag before it reaches you.

Contract Redlining and Fallback Positions

A redline is a marked-up draft showing proposed deletions and insertions. A fallback position is the concession you'll accept if the counterparty rejects your first edit.

A common fallback for a limitation of liability clause is a cap equal to 12 months of fees. Our guide on how to redline a contract in 9 steps walks through the method. Providers that store fallbacks in a playbook return faster, more consistent redlines on the next deal.

Contract Drafting From Scratch

Contract drafting means writing an agreement on your own paper, which lets you set the starting positions. Templates cover most terms, but the deal-specific terms are where drafting earns its fee.

Drafting prices vary. For example, General Legal lists $2,000 per foundational document, while Arceus Legal prices drafting by custom quote.

Contract Negotiation Across Multiple Rounds

Negotiation covers each exchange of redlines after the first review, and enterprise buyers often push three or more rounds. How a provider prices negotiation matters more than the entry price.

Arceus Legal prices negotiation from $500. By contrast, General Legal bundles unlimited turns into one $1,000 fee, which favors long negotiations.

NDA Review

NDA review checks the definition of confidential information, the term, carve-outs and whether obligations run both ways. A mutual NDA from a partner often hides a one-way non-solicit clause.

NDA pricing sits at the low end of every menu. Arceus Legal charges $250 for an NDA review, and General Legal charges $250 for simple contracts up to 3 pages.

MSA Review

MSA review covers the master services agreement that governs every later order form, so its terms repeat on each renewal. Liability caps, indemnities, IP ownership and payment terms draw most of the redlines.

A 30-page enterprise MSA falls into Arceus Legal's complex review tier at $1,000 and up. Budget for negotiation, from $500 at Arceus Legal, when the buyer's procurement team sends its own paper.

DPA Review

DPA review checks the data processing agreement against the privacy laws that apply to your customers. For EU personal data, GDPR Article 28(3) requires processor contracts to cover documented instructions, confidentiality, security measures and sub-processor terms.

Healthcare software adds a business associate agreement, governed by 45 CFR 164.504(e) under HIPAA. Requirements differ by jurisdiction, so confirm which laws cover each dataset.

SOW and Order Form Review

SOW and order form review checks the deal-specific terms that sit under an MSA: scope, deliverables, fees and acceptance criteria. An order-of-precedence clause decides which document wins when terms conflict.

These documents are short and frequent, so per-document pricing matters. Arceus Legal prices order form reviews at $250, and Outside GC includes SOWs and order forms in its commercial practice.

Contract Review Pricing Models Compared

Contract review services price work four ways: flat per document, marketplace bids, hourly rates and custom engagements. Flat per-document pricing gives the most predictable monthly spend for recurring volume.

• Flat per document: Arceus Legal, General Legal and Crosby quote a price before work starts.
• Marketplace bids: ContractsCounsel lawyers bid on each project.
• Hourly: UpCounsel lists commercial contract rates of $240 to $600 per hour.
• Custom engagement: Axiom and Outside GC price by scope.

Our position: the published negotiation price predicts your quarter-end bill better than the headline review fee. See Arceus Legal's full pricing to compare.

Turnaround SLAs and What Happens When They Slip

A turnaround SLA is a written commitment to deliver work within a set time. The strongest SLAs add a remedy when the provider misses it, and few providers publish one.

Arceus Legal's homepage promises an 8 hour turnaround on contract reviews, or the review is free. Crosby claims sub-hour reviews without a published remedy, and marketplaces leave timing to each lawyer.

Ask how the clock runs across weekends and time zones. A contract sent Friday evening before a Monday signing tests every SLA.
