eDiscovery Pricing Decoded: Where the Money Actually Goes
The pricing models, and who carries the risk
There are four common shapes. Per-gigabyte hosting charges for the volume of data held each month, which is predictable per unit but not in total. Per-document review charges for the work of looking at each document. Hybrid models mix the two. All-inclusive models bundle everything into one rate to remove surprises. The model you sign decides who carries the risk when data volumes climb or a matter runs long, so read it as a risk allocation, not just a price.
Where the cost actually sits
Most of the bill is review. Industry analysis consistently puts document review at the majority of total litigation spend. Hosting, processing, and project management make up the rest. This matters because it tells you where to focus: shaving a few cents off hosting does little, while cutting the volume of documents a human reviews changes the whole bill.
The unpredictable part: per-gigabyte and exception documents
Per-gigabyte pricing looks simple until the data grows, the matter runs for months, and exception documents arrive. Exception documents are the files that do not process cleanly and need special handling, and they are where contracts get vague. A 2026 eDiscovery pricing survey found that 39.6% of buyers could not explain how their own contracts treat exception documents. That gap is where an apparently predictable bill becomes an unpredictable one.
How to reduce eDiscovery cost without cutting corners
The largest savings come from touching fewer documents, not from cheaper handling.
- Use early case assessment to cut the data set before review begins.
- Apply assisted review to reduce the set a person has to read.
- Automate the handoffs so you do not re-collect and re-process the same data.
- Keep one defensible workflow rather than paying each tool to redo the last tool's work.
The mechanics of that are covered in the eDiscovery workflow automation guide, and the same workflow underpins legal investigations end to end. The platform that holds it together is described in the Setara overview.
Questions to ask a vendor about pricing
- How is hosting priced, and what happens as volume grows.
- How are exception documents defined and charged.
- What is included in the base rate and what is billed separately.
- How does pricing behave on a matter that runs for a year.
- What does it cost to produce and to export at the end.
Frequently asked questions
Why is eDiscovery so expensive?
Because document review, the work of a human looking at each document, is the majority of the cost. The pricing model around it then decides how predictable the rest of the bill is.
What is the most predictable eDiscovery pricing model?
All-inclusive pricing removes most surprises by bundling hosting, processing, and review into one rate. Per-gigabyte models are predictable per unit but not in total, because the total depends on volume and time.
How can I reduce eDiscovery costs?
Cut the number of documents that reach human review using early case assessment and assisted review, and automate the handoffs so the same data is not collected and processed more than once.
