Even with careful planning, an eDiscovery project can cost more than initially expected.
Data volumes increase. New custodians emerge. Additional users need access. Review requirements evolve. A production deadline moves forward, creating an urgent need for more support.
A change in cost does not necessarily mean something has gone wrong. Discovery matters often evolve as new facts and data sources come to light. But when spending changes, legal teams should understand why, what happens next, and whether there is an opportunity to adjust the project before additional costs accumulate.
Here are five questions to ask when eDiscovery costs change mid-project.
Start by comparing the current project with the assumptions used to create the original estimate.
An eDiscovery estimate may have been based on a defined number of custodians, an anticipated data volume, specific data sources, a certain number of platform users, and an expected level of support. If one or more of those assumptions has changed, the cost may change with it.
Ask your provider to identify the specific difference between the original scope and the project as it exists today.
Common changes include:
The explanation should be more specific than “the matter grew.”
For example, did the collected data expand during processing? Did the legal team add mobile devices or collaboration data? Did an additional group of reviewers require access? Did a new production request create work that was not included in the original eDiscovery agreement?
Clear answers help legal teams determine whether a cost increase is reasonable, avoidable, or the result of a misunderstanding about the original scope.
Once you know what changed operationally, identify how that change connects to the pricing model.
An eDiscovery project can include charges for processing, hosting, storage, users, collections, productions, project management, analytics, support, exports, and other specialized services. A cost increase may come from one category or from several smaller changes happening at the same time.
Ask for an itemized explanation that connects the additional work to the applicable eDiscovery pricing terms.
For example:
This is where the wording of the eDiscovery vendor contract becomes especially important. The agreement should explain how changes are approved and priced, including whether the original rate card applies to work outside the initial scope.
Legal teams should not have to reverse-engineer an invoice to understand why the projected cost changed.
Not every cost increase will affect the remainder of the project in the same way.
Some costs are tied to a one-time event, such as collecting a mobile device, processing a new dataset, preparing an additional production, or completing an urgent technical task.
Other changes can affect the monthly cost for as long as the matter remains active. Additional hosted data, more users, an expanded review team, or a greater level of support may create recurring expenses.
That distinction matters for budgeting.
Ask your provider to separate:
If monthly hosting increases because another 500 GB of data was added, how long is that data expected to remain active? Could some information eventually move to an archived environment? If more reviewers were added to meet a deadline, will those user charges continue after the review period ends?
A relatively small recurring increase can become significant if a matter remains active for another year. Understanding the duration of a cost change is just as important as understanding the amount.
A change in projected cost should prompt a conversation about available options, not simply a revised invoice.
Ask whether the team can modify the workflow, technology, support model, or data strategy to manage future spending without compromising quality or defensibility.
Depending on the matter, potential options may include:
The goal is not to cut corners. It is to make sure the project continues to use the right resources for the work that remains.
For example, AI-assisted workflows and analytics may help reduce manual effort, but technology should be introduced with clear validation, documentation, and human oversight. Similarly, reducing active data may lower hosting costs, but retention obligations and future discovery needs should be considered before information is archived or removed.
Good cost control comes from aligning people, technology, and process with the actual needs of the matter.
Understanding why costs changed is only useful if the legal team can use that information to plan what comes next.
Ask your provider for an updated estimate based on the current scope and the remaining work.
That estimate should account for known variables such as:
It should also identify the assumptions behind the revised estimate.
For example, the updated projection might assume that no additional custodians will be added, the current data volume will remain stable, five users will continue to access the platform, and the matter will stay active for six more months.
Those assumptions give the legal team a benchmark. If the project changes again, the team can more easily understand how the new development may affect spending.
When significant uncertainty remains, consider requesting baseline, moderate-growth, and high-growth scenarios. A range can provide a more realistic basis for forecasting than a single estimate.
The five questions above can help legal teams understand what is driving a cost increase, evaluate opportunities to manage spending, and establish a clearer picture of what the remaining project will require.
Ongoing visibility is just as important. Regular reporting on data volumes, active users, hosting, support usage, review progress, and upcoming work can help identify changes before they appear on an invoice. The goal is to understand not only what has already been spent, but also what is driving that spend and what is likely to happen next.
When eDiscovery costs change, revisiting the assumptions behind the original estimate can also help legal teams understand how current project requirements affect monthly spending.
Our interactive eDiscovery Cost Calculator allows you to explore estimated monthly pricing based on three key project requirements:
Adjusting these inputs can help illustrate how an evolving project may affect estimated monthly costs and give your team a starting point for a more detailed conversation.
Every matter is different. For a more tailored estimate, our team can review the specific requirements, workflows, and support needs affecting your project.
A cost change does not automatically signal a problem. An unexplained cost change does.
When the budget begins to shift, legal teams should be able to identify what changed, understand which pricing terms apply, distinguish temporary costs from ongoing expenses, evaluate available options, and receive an updated estimate for the work ahead.
The objective is not simply to reduce spending. It is to create greater predictability around how the matter is being managed and where the budget is going.
With greater visibility into what is driving costs, legal teams can respond earlier, adjust the project where appropriate, and avoid larger budget surprises later.
