What Is Ghost Billing in eDiscovery?
Ghost billing occurs when an eDiscovery vendor continues to charge monthly hosting, storage, or maintenance fees for a project that has been legally closed, settled, or abandoned. The data still sits on the vendor's servers. The meter still runs. And in the overwhelming majority of cases, the client has no idea.
The term "ghost billing" is industry slang — vendors certainly don't use it in their proposals. But among practitioners who've audited client invoices, it's a well-known phenomenon. Projects that wrapped up 18 months ago. Datasets from cases that settled before trial. Custodian collections from employees who left the company years back. All of it still hosted. All of it still billing.
The Numbers Are Not Small
A mid-sized corporate legal department running 8–12 concurrent matters at any given time may have 20–30 "closed" projects still on vendor platforms. At typical hosting rates of $25–$75 per GB per month, a 500 GB dataset generates $12,500–$37,500 in monthly charges — for data nobody is touching.
Why Ghost Billing Happens — And Why Vendors Let It
There's no conspiracy here — just misaligned incentives and organizational inertia. The vendor's contract typically states that data will be retained until the client formally requests deletion or export. If the client never asks, the data stays. The invoice keeps arriving. And because legal ops teams are stretched thin, line items on recurring invoices rarely get scrutinized the way one-time charges do.
There are three common mechanisms through which ghost billing persists:
1. No Formal Matter Closing Process
Most legal teams have no standardized checklist for closing an eDiscovery matter. When a case settles, the focus is on the settlement — not on firing off a data deletion notice to the vendor. So the project lingers in an "active" status indefinitely.
2. Contract Language That Puts the Burden on You
Read your vendor contract closely. The phrase to look for is something like: "Client shall provide written notice to initiate data deletion. Hosting fees accrue until deletion is confirmed in writing." This is intentional. Without a formal written request, the vendor has no obligation to stop billing — and every incentive not to remind you.
3. Invoice Fatigue in Busy Departments
eDiscovery invoices are notoriously complex — dozens of line items, per-GB charges, per-user fees, processing surcharges. Accounts payable processes them on autopilot. Nobody is cross-referencing active matter lists against vendor invoices on a monthly basis. The vendor knows this.
Ghost billing isn't a billing error you can dispute — it's technically legitimate under most vendor contracts. The only way to stop it is to proactively close matters in writing and build that process into your standard matter management workflow.
How to Identify Ghost Billing in Your Current Invoices
If you've never audited your eDiscovery invoices against your active matter list, there's a reasonable chance you're currently being ghost billed. Here's how to find out.
Step 1: Pull Your Last 12 Months of Invoices
Request a full billing history from every eDiscovery vendor you use. Ask for it itemized by matter or project name, with GB counts and associated dates. Most vendors can generate this report within 24–48 hours if you ask directly.
Step 2: Cross-Reference Against Your Active Matter List
Pull your current active litigation hold register or matter management system. Every project that appears on a vendor invoice but does not appear on your active list is a candidate for ghost billing. Flag all of them.
Step 3: Calculate the Bleed
For each flagged matter, multiply the monthly GB charge by the number of months since the case closed. The result is your retroactive exposure. Depending on your matter volume, this number can be sobering.
| Matter | Closed | GB Hosted | Monthly Rate | Months Billed | Total Overcharge |
|---|---|---|---|---|---|
| Smith v. Acme (2023) | Mar 2023 | 340 GB | $45/GB | 36 mo | $550,800 |
| Jones Regulatory (2024) | Jan 2024 | 180 GB | $40/GB | 14 mo | $100,800 |
| Internal Investigation Q1 | Apr 2024 | 95 GB | $50/GB | 11 mo | $52,250 |
The Contract Language That Stops Ghost Billing
The most effective intervention happens before you sign. These are the specific clauses to negotiate into every new eDiscovery vendor agreement:
"Vendor shall provide Client with a written notice of all active matters and associated hosting charges on a quarterly basis. Client shall have 30 days to confirm continuation or initiate deletion at no charge."
"Upon written notice of matter closure, Vendor shall cease billing within 5 business days. No additional hosting fees shall accrue following Client's written notice, regardless of the timing of actual data deletion."
"Any matter with zero user activity for 90 consecutive days shall be flagged by Vendor to Client via email. Continued hosting beyond this notice shall require Client's affirmative written authorization."
"Client reserves the right to audit Vendor billing records at any time and request credit for any hosting charges applied to matters closed for more than 60 days without Client's written continuation authorization."
The Matter Closing Checklist
Build this into your standard workflow. When any matter reaches resolution, the following steps should happen within 30 days:
- Confirm final legal hold release in writing with legal counsel
- Notify eDiscovery vendor in writing that matter is closed
- Request final billing statement and confirm no outstanding charges
- Determine if data requires preservation (regulatory hold, appeal window) or can be deleted
- If deleting: request written certificate of destruction from vendor
- If preserving: negotiate flat annual rate for cold storage — not per-GB monthly
- Remove matter from active vendor project list and confirm in writing
- Document closure date, data disposition, and confirmation in matter file
Negotiating Cold Storage: The Right Way to Retain Closed Data
Sometimes you can't delete. Appeal windows, regulatory requirements, insurance obligations — there are legitimate reasons to retain data after a matter closes. The mistake is paying active hosting rates for truly inactive data.
Cold storage — archival retention at dramatically reduced rates — is a standard offering from most major eDiscovery platforms, but vendors don't volunteer it. You have to ask. Market rates for cold or archival storage run $1–$5 per GB per month, compared to $25–$75 per GB for active hosting. On a 500 GB dataset, that's the difference between $37,500 and $2,500 per month for the exact same files.
Negotiate cold storage at the time of matter closure, not when you realize you've been paying active rates for two years.
The Bottom Line
Ghost billing is the most preventable cost in eDiscovery. It requires no technology, no platform migration, and no renegotiation of core pricing. It requires a process: a matter closing checklist, a quarterly invoice audit, and contract language that puts dormancy monitoring on the vendor instead of you.
The legal teams that build these processes stop paying for ghosts. The ones that don't keep funding them — often indefinitely.
