Is It Time to Fire Your Big Law Firm for Fixed-Fee Outside Counsel?

Your startup has grown. Contracts are moving faster. Vendors need agreements. SaaS providers send new terms every week. Customers want changes before they sign.

Then the legal bill arrives.

It is higher again, yet you cannot identify a new legal problem that requires all that spending. You look at an invoice and see hours billed for contract reviews, emails, calls, and routine redlines.

At this stage, the question is not whether your company needs legal support. It is whether your current law firm is still the right model for day-to-day work.

A large law firm may have been the right choice for incorporation, fundraising, a major dispute, or an acquisition. But routine contract work is different. If your team reviews several vendor and SaaS agreements every month, paying $900 an hour for each review may no longer make financial sense.

That is where fixed-fee outside general counsel can become a better fit.

The Billable Hour May Be Working Against You

Hourly billing gives you access to legal expertise, but it also makes your legal budget unpredictable.

According to the Thomson Reuters Institute, outside counsel worked rates grew about 7.3% in 2025. That was more than twice the inflation rate. At the same time, most legal spending still runs through hourly billing, even as law firms promote technology and AI tools as ways to improve efficiency.

There is another warning sign. Total legal spending as a share of company revenue reached a six-year low in 2026. That suggests companies are limiting the amount of legal work they send to counsel because of cost.

For a growing startup, that can create the wrong incentive. You may delay getting legal advice because you are worried about the invoice. Small contract issues then sit unresolved until they become larger problems.

A predictable legal structure can remove some of that friction.

What Does Fixed-Fee Outside General Counsel Cover?

Outside general counsel, or OGC, uses a different billing structure.

Instead of starting every matter with a meter running, you agree on a defined monthly scope and a fixed fee.

A typical OGC arrangement can cover routine work like:

• Reviewing vendor, SaaS, and customer contracts against your company’s standard playbook.
• Handling routine redlines within an agreed response time.
• Giving your team direct access to a senior attorney who understands your business.
• Providing a predictable monthly legal budget for finance planning.

The key is scope.

A fixed monthly fee does not automatically mean every legal matter is covered. A good OGC agreement should clearly explain what the monthly fee includes and what sits outside the scope.

For example, routine SaaS contract reviews may be covered while a financing round, litigation, acquisition, or major regulatory matter may require a separate fee.

Why Vendor and SaaS Contracts Can Drive Legal Costs

Your vendor list grows quickly as your company grows.

You may have software providers, marketing platforms, payroll services, cloud infrastructure, consultants, data providers, and other vendors. Each agreement can create another round of legal review.

Under hourly billing, every redline adds to the invoice. Ten routine contracts can become a meaningful monthly expense.

An OGC playbook changes the economics.

Your attorney can work from agreed positions on issues like liability, indemnification, termination, confidentiality, data protection, insurance, and governing law. Routine terms can then move through review faster without starting from scratch every time.

The result is not just a lower bill. Your legal process becomes easier for the business team to follow.

When Does Moving Away From Big Law Make Sense?

You do not need to leave your law firm simply because its rates increased.

The better signal is legal work volume.

If your company is reviewing more than a handful of contracts each month, occasional hourly support may no longer be the best structure. You may be paying premium rates for work that follows repeatable patterns.

That does not mean you need to cut ties immediately.

What the Transition Actually Looks Like

A short overlap period can make the change easier.

You can move routine contract review to the new OGC arrangement while keeping your existing firm available for a live financing, dispute, acquisition, or other matter already in progress.

This gives you time to test the new relationship without creating a gap in legal coverage.

Before signing with an OGC provider, ask for more than a rate card. Request a sample contract review playbook. Ask how the provider handles matters outside the monthly scope. Speak with a real client if possible.

You are not simply buying cheaper legal services. You are choosing a different operating model.

Common Founder Mistakes

• Waiting for a legal emergency before making the change: Founders often keep the same law firm until legal spending becomes painful. By then, they may have spent months paying hourly rates for routine work that could have been handled under a predictable monthly arrangement.
• Assuming a fixed fee means unlimited work: A fixed monthly fee still has boundaries. Financing, litigation, M&A, and other major matters may create additional charges. Ask for a clear list of covered and excluded work before signing.
• Keeping Big Law for prestige during diligence: Some founders worry that investors or buyers will care which firm’s name appears on their agreements. In practice, diligence teams care more about whether contracts are consistent, complete, and properly documented than the prestige of the law firm’s letterhead.

10-Minute Outside Counsel Self-Check

• Do you know what your company has spent on average for each outside counsel contract review during the past six months?
• Can you clearly identify what your current legal engagement covers and what it excludes?
• Does your company have a written playbook for standard vendor and SaaS contract terms?
• Has your current law firm ever proposed a flat monthly arrangement, or does it only provide hourly estimates?
• Would changing counsel interfere with an active deal, financing round, or litigation matter?
• Can someone on your team handle a basic SaaS agreement redline without contacting outside counsel first?

If you cannot answer yes to most of these questions, your company may need more preparation before switching its outside counsel structure.

Bottom Line

Your legal support should match the way your company operates today.

The firm that helped with incorporation or your first major transaction may have been an excellent choice at that stage. It does not mean the same billing model is right forever.

Once your startup is signing contracts regularly, routine legal work can become a recurring operating function. Paying hourly rates for predictable contract review may leave you with a legal budget that grows faster than the business.

A fixed-fee OGC arrangement can give you a clearer monthly cost, faster access to counsel, and a repeatable process for routine agreements. You can still keep specialized Big Law support for major transactions or disputes when those matters arise.

The goal is not simply to fire your law firm. It is to build a legal structure that fits your company’s current needs.
