Contracts pile up fast once a B2B company starts selling. Every new customer brings an MSA, an order form and a redline that someone has to answer.
Early on, a founder or finance lead often handles that work between other jobs. That stops working once deals get larger and buyers start sending their own paper.
The good news is that you have more choices than a traditional firm billing by the hour. You can hire a law firm on flat fees or find a lawyer through an online marketplace.
Each model suits a different stage and contract volume. Some providers also place flexible in-house attorneys directly on your team.
This list covers seven providers that handle business and commercial contract work for US companies. It’s general information to help you compare options, and it isn’t legal advice.
How we picked
We looked for currently operating US providers that handle commercial contract work for businesses. We reviewed each provider’s own website and described only what they publish.
We weighed how each one prices its work, who does the review and which kinds of companies it fits best. Each entry ends with a limitation worth knowing before you sign up.
We left out large firms built mainly for major corporate deals. Growing companies usually need steady, day-to-day contract help more than a big-firm bench.
1. Arceus Legal
Arceus Legal is a law firm and a legal AI platform built for B2B companies with steady contract flow. Licensed attorneys work alongside AI agents, and a licensed attorney reviews and approves every agreement.
Speed is the headline. Standard contract reviews average 3 to 5 hours. Arceus guarantees an 8-hour turnaround on qualifying standard contract reviews, or the review is free.
Pricing uses flat fees quoted upfront, with no billable hours. That makes it easier for finance teams to budget legal spend before a deal lands.
Every attorney has at least 10 years of legal experience and prior in-house experience. The team’s backgrounds include firms and companies such as Apple, Google and Meta.
What they do:
- Commercial contracts, including MSAs, SOWs, order forms, NDAs, DPAs, vendor agreements, partner and reseller agreements and renewals
- Employment, product and privacy work, plus general counseling, depending on the engagement
- A named attorney for annual customers who learns the business, its preferences and its legal positions
- A record of each customer’s positions, so later contracts are reviewed against them
- Work through Slack and email, with connections to Salesforce, HubSpot and Gmail
That memory matters for repeat negotiations. Your attorney doesn’t need a fresh briefing every time a customer pushes back on the same liability cap.
Best for: B2B software and AI companies reviewing at least two negotiated contracts per month. Most clients keep outside counsel for major company events, and Arceus works alongside that relationship.
Keep in mind: Arceus doesn’t handle litigation, M&A, IP (patents), immigration or tax. You’ll need separate counsel for those matters.
2. ZwillGen
ZwillGen is a midsize law firm focused on technology, data and privacy. It has offices in San Francisco, Chicago, Washington, DC, New York and London.
Its privacy practice lists vendor and customer contracting among its services. That makes it a strong option when your contracts turn on data use, security terms or AI.
What they do:
- Vendor contracting, plus vendor and customer agreements tied to privacy and data protection
- Practices covering artificial intelligence, ad tech, fintech, information security and auto-renewing contracts and subscriptions
- Litigation, regulatory investigations, and transactions and data issues in M&A
ZwillGen’s billing philosophy page describes alternatives to straight hourly billing. Options include monthly retainers, flat or project fees, success fees and one-rate hourly pricing.
Best for: Tech and data-driven companies whose contracts carry heavy privacy, security or AI terms.
Keep in mind: ZwillGen’s site centers on privacy, data and regulatory work. A company that mostly needs high-volume sales contract review may find that focus narrower than its needs.
3. Andrew S. Bosin LLC
Andrew S. Bosin LLC is a small law firm led by attorney Andrew S. Bosin. It lists an office in Glen Rock, New Jersey, and serves clients nationwide remotely.
The firm focuses on SaaS, AI, software and tech startups. Its site promotes flat-fee legal packages and transparent pricing without hourly surprises.
What they do:
- Drafting and negotiating master service agreements, EULAs, subscription agreements and partner or reseller agreements
- Terms of service and privacy policies for SaaS platforms, including GDPR and CCPA work
- AI licensing, IP ownership and data rights for AI products
- Company formation, founder agreements and fundraising documents such as SAFEs and term sheets
Best for: Early and growth-stage SaaS and AI startups that want one attorney for core contracts and company paperwork.
Keep in mind: The site doesn’t publish package prices, so you’ll need to ask for a quote. As a smaller firm, its capacity during heavy deal periods is worth asking about.
4. Paragon Legal
Paragon Legal places experienced in-house attorneys inside client legal teams on a flexible basis. It’s based in San Francisco and works with companies of any size that have an in-house legal team.
Paragon describes itself as a legal talent provider and says on its site that it isn’t a law firm. Its attorneys act as an extension of your team, as an alternative to outside counsel or a permanent hire.
What they do:
- Flexible attorneys for workload overflow, interim coverage and project-based support
- Commercial and transactions work, including contract negotiation
- Contract managers, compliance professionals and legal operations staff
- Temp-to-permanent conversion when a role should become full time
Best for: Companies with an in-house legal team that need extra contract capacity for a busy stretch or a leave.
Keep in mind: Paragon’s model assumes you already have an in-house legal team to direct the work. Its site doesn’t publish pricing.
5. Lawtrades
Lawtrades is an online marketplace for hiring attorneys, paralegals and legal operations professionals. Companies post a role with a defined scope, then compare candidates’ experience and proposed terms.
Its commercial counsel offering covers contract backlogs, customer and vendor agreements, software and SaaS terms, and playbook updates. Many of the engagements it describes are part-time, remote and ongoing.
What they do:
- Fractional and project-based commercial counsel for contract work
- Interim cover for busy periods, leaves of absence and team gaps
- Legal operations, privacy and employment support
- Lawtrades Agent, an AI tool that helps you describe your work and explore lawyers before meeting them
Pricing depends on the lawyer you hire. Lawtrades says lawyers may propose hourly, flat fee or other arrangements, and you review proposed fees before hiring.
Best for: Legal teams and startups that want a fractional commercial lawyer for steady, ongoing contract volume.
Keep in mind: You’re choosing and managing an individual lawyer, so quality and pricing vary by hire. Expect to spend time vetting candidates.
6. ContractsCounsel
ContractsCounsel is a US online legal marketplace that connects clients with vetted attorneys across all 50 states. You post a project for free, receive bids from lawyers and pick one.
The site says lawyers often send proposals within hours, so it can move quickly on a single contract.
Attorneys on the platform quote flat fees for contract work.
What they do:
- Project-based contract drafting and review
- Business formation filings and trademark applications
- Outside general counsel and contract support for larger needs, arranged through the company
- A subscription chat service with verified lawyers, plus lawyer-drafted document templates
Best for: Companies with occasional one-off contracts that want to compare flat-fee bids side by side.
Keep in mind: Each project can go to a different lawyer, so nobody builds deep context on your business by default. That can slow down repeat negotiations with the same customers.
7. UpCounsel
UpCounsel is an online marketplace that connects businesses with attorneys. It states on its site that it isn’t a law firm and doesn’t provide legal services itself.
Businesses post a legal need, receive free proposals from attorneys and hire the one they choose. Contracts and agreements sit among its most popular legal areas. The site also describes its support as available 24/7.
What they do:
- Attorney matching for contracts, business formation, trademarks, employment, securities and general counsel work
- Online legal advice from attorneys when you need it
- A free workspace with document storage, e-signature and online payments
- Free legal documents, forms and self-help articles
Best for: Small and growing businesses that want to compare proposals from several attorneys for a defined contract project.
Keep in mind: UpCounsel doesn’t publish set prices for contract work, so costs depend on the proposals you receive. You’ll also vet each attorney yourself.
How to choose a business contract lawyer
Start with your contract volume. If you negotiate two or more contracts a month, a flat-fee firm with a dedicated attorney often fits better. Starting fresh on each project gets slow and repetitive.
Next, check who reviews the work and how much context they keep. A lawyer who remembers your past positions saves you from re-explaining the same redlines.
Look at the pricing structure as well as the rate. Flat fees make budgeting easier, while hourly and bid-based models can swing from deal to deal.
Ask about turnaround before you sign. Sales teams feel every day a contract sits in review, and a written commitment gives you something to plan around.
Then match scope to your needs. Many growing companies use one provider for everyday commercial contracts and keep separate counsel for litigation, M&A or fundraising.
Finally, think about how you’ll send work in. A provider that works inside the tools your team already uses, like Slack or email, is easier to adopt.
No single model suits every company. Your contract volume and how quickly deals need to close will narrow this list fast.
