eDiscovery costs have a way of turning a manageable litigation matter into a budget catastrophe. For small law firms, the risk is especially acute: your clients don't have the enterprise budgets that big-firm opposing counsel assumes everyone has, and the same discovery obligations apply regardless.
Here's a realistic look at what email discovery actually costs, where the money goes, and what small firms can do to manage it.
The Actual Cost Breakdown
The Association of Certified E-Discovery Specialists estimates the average cost of eDiscovery for a single case has climbed to well over $100,000 at large firms. That number is inflated by enterprise software contracts and outside vendor pricing — but the underlying cost drivers are real for firms of every size.
Where the money goes:
1. Collection ($500–$5,000+ per custodian) Collection is the process of extracting emails from email systems and preserving them for review. At large firms, this involves expensive forensic tools and outside vendors. At small firms, it often means an IT person or paralegal manually exporting files — which trades money for time.
2. Processing ($500–$2,000 per gigabyte) Raw email files need to be processed to extract metadata, deduplicate, and convert to reviewable formats. Enterprise eDiscovery platforms charge per gigabyte. The cost adds up fast when a custodian has a few years of email on record.
3. Review (the big one: $50–$200+ per hour) Document review — reading through emails to determine what's responsive and what's privileged — is where most eDiscovery money goes. A paralegal reviewing 50–100 documents per hour at even $75/hour will spend dozens of hours on a medium-sized production. Attorneys reviewing complex documents go much slower at higher rates.
4. Production ($100–$500+ per production) Formatting, Bates numbering, and producing documents costs money whether you do it in-house or with a vendor.
5. Project management (embedded throughout) Coordinating the process — tracking custodians, managing deadlines, maintaining privilege logs — adds up over a matter's lifetime.
The Small Firm Problem
Small firms face a structural disadvantage in eDiscovery. Enterprise platforms like Relativity, Everlaw, and Logikcull were built for large matters with large budgets. The per-gigabyte and per-seat pricing models are designed for firms that can spread the cost across many matters.
For a 5-attorney firm handling a single employment matter, paying $2,000 per gigabyte to process email data is not a reasonable cost to pass on to a client who's already straining to pay legal fees.
The result is that many small firms try to handle discovery with tools that aren't designed for it: Outlook search, manually organized folders, email exports they print and sort by hand. This isn't just inefficient — it creates risk. Manual processes introduce errors, lose metadata, and produce records that can be challenged.
What Actually Drives Costs Up
Before looking at solutions, it's worth understanding what makes a discovery matter expensive.
Volume without culling. The more documents that go into review, the more review costs. Effective upfront culling — narrowing the date range, filtering by custodian, excluding irrelevant domains and system-generated emails — can cut reviewable volume by 60–80% before a single document is read.
Unorganized data. When email data arrives in an unstructured state, reviewers spend time orienting themselves to the record rather than reviewing it. A clear chronological organization reduces per-document review time significantly.
Late preservation. If emails are deleted before a litigation hold is issued, recovery becomes a forensic expense rather than a standard collection cost. Courts don't excuse late preservation based on cost.
Over-production. Producing more than you need to is expensive and creates risk. Over-broad productions can waive privilege and give opposing counsel material they can use against you.
Disputes about production. When productions are challenged — because metadata is stripped, format isn't agreed upon, or documents are improperly withheld — the cost of resolving those disputes often exceeds the original production cost.
Practical Cost Management Strategies
Negotiate ESI protocols early. Before discovery begins, agree with opposing counsel on collection scope, date ranges, custodians, and production format. An agreed ESI protocol prevents expensive disputes later and often results in narrower discovery obligations.
Cull before review. Use keyword searches, date filters, and custodian limits to reduce review volume before any human reads a document. Even basic culling can cut volume dramatically.
Organize before you review. Reviewing an unorganized email dump is slower and more expensive than reviewing a structured chronological record. The time spent organizing upfront is paid back in review efficiency.
Use proportionality arguments. Under FRCP Rule 26(b)(1), discovery must be proportional to the needs of the case. For small matters, you have legitimate grounds to push back on requests that would require disproportionate cost and effort.
Educate clients on preservation costs. The cheapest thing a client can do is preserve their email early and completely. The most expensive thing is to recover poorly preserved or deleted email after litigation begins.
Right-size your tools. Enterprise eDiscovery platforms are not the only option. For small matters, purpose-built tools designed for small firm workflows offer the core functionality — organized timelines, metadata preservation, exportable records — at a fraction of the cost.
What "Good" Looks Like
A well-run small firm eDiscovery process looks like this: email preserved at the time the litigation hold issues, organized chronologically so counsel can understand the record quickly, culled to the relevant custodians and time period before review begins, and produced in an agreed format without metadata stripped.
That process doesn't require expensive enterprise software. It requires discipline, early action, and tools appropriate for the matter size.
The firms that keep eDiscovery costs under control aren't using more expensive tools than everyone else. They're using better processes and making better decisions earlier in the matter.
