The complete guide to corporate ediscovery budgets

eDiscovery software costs are hard to budget because most of them scale with data volume and matter length, and neither one is known when a matter opens. Corporate legal teams that build defensible budgets do three things: they know what each cost category actually covers, they pick a pricing model that matches their matter profile, and they hold vendors to clear terms before the data shows up.

The stakes are real. In a Gartner survey of 200 in-house and law firm lawyers, legal matters stayed within planned budgets only about 20% of the time. And ComplexDiscovery projects total ediscovery spending will grow from $16.89 billion in 2024 to $25.11 billion by 2029.

This guide walks through where the money goes, how the common pricing models compare, and a step-by-step process for building an ediscovery budget your CFO will sign off on.

Key takeaways

• Review is still the biggest line item. It's an estimated 62% of ediscovery task spend in 2025, followed by processing (21%) and collection (17%).
• Per-GB pricing is the least predictable model. Hosting fees keep billing every month a matter stays open, including the months it sits dormant.
• Per-user pricing ties cost to your team, not your data. That makes it far easier to forecast across a portfolio of matters.
• In-house teams are taking more work back. 65% of law departments in Harbor's 2025 survey made intentional efforts to keep work in-house.
• A defensible budget starts with your own history. Audit 12 to 24 months of spend before you pick a model or a vendor.

What do ediscovery software costs include?

eDiscovery software costs include every fee tied to moving electronic evidence from collection to production: processing, hosting, review, productions, user licenses, and project support. Some vendors bundle these together. Many bill each one separately, which is where budgets start to drift.

Here's what each category covers and how it's typically billed, using market rates from ComplexDiscovery's Summer 2025 eDiscovery Pricing Survey.

The costs that don't show up in the quote

The line items above are the visible ones. These are the ones that tend to surface later:

• Hosting on dormant matters. Per-GB hosting bills every month whether anyone logs in or not.
• Production and export fees. Some vendors charge per production, per page, or per GB exported.
• Sharing fees. Giving outside counsel or co-counsel access can mean added seats or per-matter charges.
• Re-processing. Reusing data in a related matter sometimes means paying to process it again.
• Overages. Tiered plans can jump to a higher rate once a matter crosses a volume threshold.

Why do corporate legal teams struggle to budget for ediscovery?

Corporate legal teams struggle because the biggest ediscovery cost drivers (data volume, matter length, and review hours) aren't known until a matter is well underway. Finance wants a fixed number in January. Litigation doesn't work that way.

Data volume is unknown at the start

You can't predict how many custodians a matter will touch or how much Slack, Teams, and mobile data will come with them. Under per-GB pricing, every surprise gigabyte shows up on the invoice.

Matters run long, and hosting keeps billing

Legal holds, appeals, and slow settlement talks keep data on a platform for years. Per-GB hosting charges for every one of those months, even when no one is reviewing anything.

Multiple outside counsel means multiple vendors

When each firm brings its own vendor, a legal department ends up with different pricing models, different invoices, and no single view of total spend. RAND's landmark study found outside counsel consumed about 70% of total ediscovery production costs across the 57 productions it examined.

Budget pressure keeps rising

Legal departments are being asked to do more without more money. In IPRO's survey of 126 in-house professionals, 53% said budget issues were their biggest challenge for the year. In Harbor's 2025 survey, only 47% of departments expected inside legal spending to increase, down from 65% the year before.

Proportionality cuts both ways

Federal Rule of Civil Procedure 26(b)(1) limits discovery to what's proportional to the needs of the case, including “whether the burden or expense of the proposed discovery outweighs its likely benefit.” That's a useful argument, but only if you can document what discovery actually costs. A clear budget is also your evidence.

How does ediscovery pricing work?
The 5 common models

Most ediscovery pricing falls into five models. The right one depends on how many matters you run, how much data they carry, and how long they stay open.

‍

Per-GB pricing

Per-GB is the longest-standing model in ediscovery. You pay to process each gigabyte, then pay a monthly rate to host it. It looks cheap on a single small matter. It gets expensive when data volumes grow or matters run for years, because hosting never stops.

Per-matter pricing

Per-matter pricing gives you a clear number for each case. That works until your caseload grows. Ten matters means ten fees, even when those matters share custodians and data.

Per-user pricing

Per-user pricing ties cost to the size of your team instead of the size of your data. You pay a predictable monthly rate per user, and hosting is included. For corporate legal teams juggling several matters at once, it's the easiest model to forecast. Ask how processing is handled, since plans typically include monthly processing limits based on plan level.

Enterprise licensing

Enterprise agreements trade flexibility for a lower unit rate. They make sense for departments with consistent, high-volume needs. Read the fine print on minimum commitments and what happens if your volume drops.

Managed services hybrids

Some vendors bundle software with their own staff for processing, review, and project management. That can fill a gap if you have no in-house ediscovery team. Just know that project management alone commonly runs $100 to $200 per hour, and 31% of survey respondents reported rates above $200.

What about AI-assisted review pricing?

Generative AI review is still finding its pricing footing. In ComplexDiscovery's Summer 2025 survey, per-document billing led at 37%, followed by hybrid approaches at 30%. The most common defined rate was $0.26 to $0.50 per document. Nearly half of respondents (46%) weren't sure what they paid, which is a good reason to ask vendors to spell it out.

What drives ediscovery costs up (or down)?

Review has always been the largest share of ediscovery spend, but that share is shrinking as collection gets more complex and technology takes on more of the review work.

‍

Within those categories, six factors move your costs most.

Data volume, and how early you cull it

Every gigabyte you remove before review saves processing, hosting, and attorney time. Early case assessment lets you search and filter data before committing to full review. Tip: Run search term hit reports before you agree to terms with opposing counsel.

Data types

Email is predictable. Slack, Teams, text messages, and structured data are not. Modern data sources take more effort to collect and process, which is part of why collection's share of spend keeps climbing. Tip: Ask vendors exactly which formats they process natively.

Matter duration

The longer a matter stays open, the more it costs under any model that charges for hosting. Tip: Track how many of your hosted gigabytes belong to matters with no activity in the last 90 days.

Reviewer count and outside counsel touchpoints

More reviewers means more seats and more coordination. Every handoff to outside counsel is a chance for duplicate work. Gartner estimates the average legal department spends $162,000 a year paying lawyers to duplicate, at least in part, the efforts of outside counsel. Tip: Keep one shared database across your team and outside counsel.

Productions

Productions and re-productions can carry their own fees. Tip: Confirm whether productions, exports, and privilege logs are included or billed separately.

In-house vs. outsourced review

Review is where outside spend concentrates. Technology-assisted review can cut review hours sharply. RAND estimated predictive coding could reduce attorney review hours by about three-quarters. Tip: Decide which matters your team can review in-house before you sign an engagement letter.

How to build a defensible ediscovery budget, step by step

A defensible ediscovery budget is built on your own spending history, matched to a pricing model that fits your caseload, and reviewed with finance on a set schedule. Here's how to build one.

1. Audit 12 to 24 months of spend. Pull every ediscovery invoice, including those passed through outside counsel. Group charges by category: processing, hosting, review, productions, project management.
2. Profile your matters. Sort matters by type (employment, commercial, regulatory, internal investigations) and note typical data volume, custodian count, and duration for each.
3. Find your dormant data. Total the gigabytes hosted on matters with no review activity in the last 90 days. This is often the easiest money to recover.
4. Choose a pricing model that matches your profile. Many concurrent matters with long tails favor per-user pricing. A few small, short matters may be fine on per-GB.
5. Decide what stays in-house. Identify which matters your team can process, review, and produce on its own, and which need outside counsel or managed review. See how one corporate legal team brought ediscovery in-house.
6. Build in a contingency. Set aside a reserve for the matter you can't predict, such as a regulatory inquiry or a large internal investigation.
7. Set quarterly checkpoints. Compare actual spend to budget with finance every quarter, and adjust before the gap gets wide.

The payoff for active management is real. Gartner found lawyers who are effective at active matter management are twice as likely to keep matters within budget.

Example: what dormant data costs

Illustrative numbers. Say your department hosts 1,500 GB across 20 matters at $10 per GB per month, the top of the most common market band for basic hosting.

That's $72,000 a year spent storing data no one is reviewing, before a single new document is processed. Under a per-user model with hosting included, that line drops out of the budget entirely, and cost follows the people doing the work.

How to evaluate ediscovery vendors on cost

The best way to compare ediscovery vendors on cost is to ask every vendor the same questions and get the answers in writing. Use this checklist in your RFP or demo calls.

Corporate legal teams have more leverage here than they may realize. In one survey of legal operations professionals, 74% said they control which ediscovery vendors their outside counsel uses. If you're paying the bill, you get to set the terms.

Bringing ediscovery in-house:
when it saves money

Bringing ediscovery in-house saves money when your team handles enough matters to keep a platform busy, and when the platform's pricing doesn't punish you for the data those matters carry. More corporate legal teams are making the move:

• 65% of law departments made intentional efforts to keep work in-house in the last one to two years (Harbor, 2025)
• Only 37% expect outside counsel spend to increase, down from 58% the year before (Harbor, 2025)
• 40% of in-house teams were already doing most of their ediscovery themselves to save money (IPRO, 2023)

In-house doesn't mean going it alone. The goal is to own the platform and the data, then bring outside counsel in where their expertise matters most.

Case study:
A global electronics company takes ediscovery in-house

Meridien Technologies is a global consumer electronics company whose legal department handles a steady volume of commercial and IP litigation. (The company's name was changed to preserve its anonymity.) For years, every ediscovery matter meant routing data through outside law firms or a third-party provider's platform. The team says that process had a major negative impact on time, cost, and efficiency.

After vertically integrating Nextpoint, the legal team now collects, reviews, and produces ediscovery in-house, sharing a clear view of the record with outside counsel during production review. On one complicated IP litigation production alone, Nextpoint saved the team an estimated 30 hours of internal time.

Frequently asked questions

How much does eDiscovery software cost per GB? In ComplexDiscovery's Summer 2025 pricing survey, the most common processing rate was under $25 per GB at ingestion. Monthly hosting was most often under $10 per GB without analytics and under $15 per GB with analytics. Those rates repeat every month the data stays hosted.

What is the most expensive part of eDiscovery? Document review. ComplexDiscovery estimates review accounted for 62% of ediscovery task spend in 2025, down from 73% in RAND's 2012 study. Processing was 21% and collection 17%.

Is per-user pricing cheaper than per-GB pricing? For most corporate legal teams running several matters at once, yes. Per-GB costs rise with every gigabyte and every month a matter stays open. Per-user costs stay tied to team size, which makes them easier to forecast and often lower over the life of long-running matters.

How big is the eDiscovery market? ComplexDiscovery projects total ediscovery spending will grow from $16.89 billion in 2024 to $25.11 billion by 2029, an 8.25% compound annual growth rate.

How can corporate legal teams reduce eDiscovery costs? Cull data early with search and early case assessment, move long-running matters off per-GB hosting, keep one shared database with outside counsel, and bring routine review in-house. Then track actual spend against budget every quarter.

Should corporate legal departments own their eDiscovery platform? Owning the platform gives you control over the data, the vendor terms, and the total cost. In Harbor's 2025 survey, 65% of law departments made intentional efforts to keep work in-house. Outside counsel can still work in your platform when you need them. One global consumer electronics company saved an estimated 30 hours on a single IP production after bringing ediscovery in-house.

What hidden fees should I ask eDiscovery vendors about? Ask about hosting on dormant matters, production and export fees, sharing fees for outside counsel, re-processing for related matters, overage rates, and hourly project management. Request a sample invoice for a matter similar to yours.

How is AI document review priced? Most often per document. In ComplexDiscovery's Summer 2025 survey, 37% of respondents cited per-document billing as the primary model, and the most common defined rate was $0.26 to $0.50 per document.
