Is most eDiscovery pricing hybrid?

Most real contracts combine meters, which means a reader comparing per-GB against a flat rate is often comparing two things neither provider is offering. A price sheet with a platform fee, a per-gigabyte hosting line and hourly project management is three meters in one agreement, and it behaves like none of the three pure models on its own.

Which part of a hybrid contract should you negotiate?

The component that varies, not the one with the largest headline number. A large fixed floor beside a small volume charge is already close to predictable and negotiating the floor changes a number you could always forecast. Reducing the rate on the variable component, or capping it, changes the part of the bill you cannot forecast, which is where the risk actually sits.

Where do project management hours sit in a hybrid contract?

On top, as a services layer rather than as a model of their own. Hourly work such as project management, collection and support is metered by vendor effort, so it moves when the provider's involvement moves rather than when your data or your team does. It is the component clients most often forget to forecast, because nothing about it scales with anything they control.

Hybrid pricing in eDiscovery: which part of it moves

Hybrid pricing combines more than one meter in a single agreement, most often a fixed platform fee alongside a per-gigabyte charge, a seat charge, or hourly services. Because the components move independently, the arrangement behaves like whichever meter carries the larger share of the total. The useful question about a hybrid contract is therefore not whether it is one, but which part of it moves.

How does hybrid pricing work?

Two or more meters run at once, and they answer to different things.

A fixed component answers to time: it is the same this month as last, whatever happened to the matter. A volume component answers to data, so it moves when the other side produces or a new custodian is collected. A seat component answers to headcount, so it moves when the review team is staffed up. An hourly component answers to the provider’s own effort, which is the only one of the four that moves for reasons on the vendor’s side of the relationship.

The proportion between them is what determines the character of the contract, and the same two components in opposite proportions produce opposite experiences. A large fixed floor with a small per-gigabyte line behaves like a fixed arrangement, and the volume charge is noise around a number you can forecast. A small platform fee with a large per-gigabyte line behaves like per-GB pricing with an entry charge attached, and the forecast is only as good as your estimate of the data.

Reading a hybrid therefore means doing something a headline rate never asks for: working out which line dominates at the volumes and durations you actually expect, rather than at the ones in the example. That calculation is the whole of the model, and it is why two quotes described identically can behave nothing alike.

What does hybrid pricing look like in practice?

The components sort cleanly by what each one answers to, which is the fastest way to read an unfamiliar price sheet.

The four components of a hybrid arrangement, by what makes each one move
Component	Meter	Moves when
Platform or subscription fee	Time	The term changes, and not otherwise
Data charges	Volume held or processed	Data is collected, produced or retained longer
Seat charges	Headcount with access	The review team is staffed up or down
Services	Vendor hours	The provider’s involvement changes

Bundling is the direction of travel, and the clearest evidence for it is where a single meter has stopped carrying a service. In the Winter 2026 eDiscovery Pricing Survey, 35.8% of the 53 respondents reported an alternative pricing model for predictive coding and technology-assisted review, the highest such proportion of any per-gigabyte question in that survey, with the analysis concluding that standalone per-gigabyte TAR billing “is becoming the exception”. The same survey describes user licensing moving toward “enterprise agreements, volume tiers, and managed service arrangements that bundle access costs into broader contract structures”.

What the survey does not measure, and says so, is whether bundling is a net advantage. It observes that bundling reduces per-matter cost visibility and that the answer depends on volume, negotiated terms, and how closely usage tracks contracted scope. That is the honest position: a bundle can be cheaper and less legible at the same time.

How does hybrid pricing show up on an eDiscovery invoice?

As several lines that are not comparable with one another, which is the practical difficulty of the model.

A fixed line, a hosting line that grows with retained data, a processing line that appears whenever a tranche arrives, a seat line that tracks the team, and services billed by the hour. Each is legible on its own; together they make month-on-month comparison hard, because a rise in the total does not say which meter caused it.

Worth asking, in this order: which component is fixed and for how long, which is the largest at your expected volume, what the unit rate is on each variable component, whether any of them is capped, and what the total looks like at twice your expected data and at twice your expected team. The Fee Field Guide decodes each line individually, and the models comparison sets the combined structures against the pure ones.
