The Real Cost of Expert Today — and What You Get for It

On-Prem Vs. Cloud Costs

On-premise systems look cheap on paper — software licenses are a known cost. But that’s just the visible tip of the iceberg. Underneath sits the real expense: hardware, IT personnel, security patching, database tuning, and constant training, all adding up to unpredictable, back-loaded costs that surface long after purchase.

Cloud-based systems flip that model. The visible cost is a subscription fee, and the hidden costs shrink to just implementation and training — nothing more. That’s the real difference: on-premise spending is a surprise waiting to happen, while cloud spending is fixed and known upfront. It’s not just about spending less. It’s about spending predictably.

What Firms Are Actually Paying Today, Beyond the License

The Expert license fee is the visible cost. Underneath it, most firms are also carrying:

• Hardware refresh. Servers age out on a 3-5 year cycle. Someone has to spec, procure, and replace them — and that capital expense rarely gets mentally attributed to “running Expert,” even though it exists because of it.
• Hosting and infrastructure. Whether it’s an on-prem data center or hosting arrangement, there is a real reoccurring cost to facilities, maintaining infrastructure, managing recoverability and overall availability.
• Security tooling. Endpoint protection, monitoring, patching and the tooling and teams required to keep a self-hosted legal system defensible against modern threats.
• IT headcount and hours. Time spent by internal IT staff — or outside consultants — patching, troubleshooting, and maintaining the environment is a real cost, even when it’s absorbed into existing salaries rather than billed as a line item.
• Microsoft lifecycle catch-up. Server OS versions, SQL Server versions, and supporting infrastructure all have their own upgrade cycles that have to be kept current — often on a different timeline than the Expert upgrade cycle itself, which compounds the work.
• Support overhead. Time spent managing support tickets, escalations, and vendor coordination across multiple layers of infrastructure instead of one.
• Productivity drag. Downtime, slow performance, and the cumulative time lost to an aging or overburdened environment rarely get quantified, but they’re a real cost paid in staff hours, every week.

None of these show up on the same invoice as the Expert license. That’s exactly why they get left out of the comparison.

Why These Costs Disappear Into the Operating Budget

These aren’t hidden costs in the sense that no one knows about them — IT knows. Finance approves the capital requests. The costs are simply diffuse. Hardware sits in a capital budget. Hosting sits in an infrastructure line. IT hours sit in payroll. Security tooling sits in a separate vendor category entirely.

When none of these costs are labeled “cost of running Expert,” they don’t get added up as one. The Expert license fee ends up looking like the entire cost of the system, when it’s really just the cost of the software layer sitting on top of everything else the firm is funding to keep that software usable.

That’s the incomplete comparison. Sierra’s price isn’t being weighed against the true cost of the current state — it’s being weighed against a fraction of it.

What Sierra’s All-In Price Actually Replaces

Sierra’s pricing is a single, fixed number. What it replaces isn’t just the license — it’s every category listed above:

• No hardware refresh cycle, because there’s no on-prem hardware to refresh.
• No separate hosting cost, because hosting is included.
• No standalone security tooling budget, because infrastructure security is part of the service.
• Reduced IT headcount burden, because the operational maintenance work shifts to Aderant.
• No Microsoft lifecycle catch-up, because that layer is maintained continuously as part of the platform.
• Lower support overhead, because there’s one vendor accountable for the full stack instead of several.
• Less productivity drag, because the environment is maintained to a consistent performance standard.

The 2-3× comparison holds only if you compare Sierra’s price to the license fee alone. Compared to the full, actual cost of running Expert today, the gap narrows substantially — and for many firms, closes or reverses.

The 3-Year Comparison: Current State vs. Sierra State

A conservative, apples-to-apples view over a 3-year horizon typically includes:

Current state (Expert, self-hosted or self-managed):

• Expert license/maintenance fees (3 years)
• Amortized hardware refresh cost
• Hosting/infrastructure costs
• Security tooling costs
• Allocated IT staff time
• Microsoft licensing and lifecycle costs
• Estimated productivity loss from downtime and aging infrastructure

Sierra state:

• Sierra subscription fee (3 years, fixed)
• Migration cost (one-time, amortized across the term)

When firms build this comparison honestly — using their own numbers rather than assumptions — the total cost of ownership gap is almost always smaller than the sticker-price comparison suggested, and in a meaningful number of cases, Sierra comes out ahead. The specific outcome depends on each firm’s current infrastructure age, staffing model, and hosting arrangement, which is exactly why this comparison is worth building with real figures rather than estimating from the license fee alone.

Customer Proof: What This Looks Like in Practice

Firms that have already migrated are the clearest evidence that the operational side of this math holds up. Holland & Knight, Kostelanetz, and Rivkin Radler have each moved to Sierra and can speak directly to the operational shift — reduced infrastructure management, fewer support escalations tied to environment issues, and IT time redirected away from maintenance and toward higher-value work.

“With Expert Sierra, we are embracing the latest technology while maintaining our customizations, integrations and progressive approach to leverage powerful time and billing solutions that will help us deliver the high standard of excellence our clients expect and deserve.” – Mia Stutzman, CFO of Holland & Knight.

The 2-3× objection is a fair question asked with incomplete information. The way to answer it isn’t to argue the multiple down — it’s to build the comparison with your firm’s actual infrastructure, staffing, and hosting costs on the table.
