Day One vs. Year Three: The Value Sierra Unlocks Now (and Next)

Value Isn’t a Moment – it’s a Curve

Most software conversations frame ROI as a single moment: you migrate, you flip the switch, you get the new system. Sierra doesn’t work that way, and that’s the point. Because Sierra runs on the Aderant Stridyn platform, the value isn’t fixed at go-live — it compounds. Some benefits land immediately. Others build over the following year. And the platform keeps shipping new capabilities well beyond that.

The firms getting the most out of Sierra aren’t evaluating it as “what do we get on day one.” They’re evaluating it as a curve — and the curve keeps climbing.

Day One: The Foundation Improves Immediately

Before any new feature ships, the infrastructure underneath the firm’s daily operations changes for the better:

• 99.99% uptime. The system your billing, finance, and administrative teams depend on all day is available essentially all the time — no more planned outages for patching or unplanned downtime from aging on-prem hardware.
• 57% of Support Tickets in Under One Day.
• Enterprise-grade security. Firms get security tooling, monitoring, and practices that would be expensive and complex to build and maintain independently.
• A day-one performance lift. Firms running on aging hardware or overburdened infrastructure typically notice the system is simply faster; reports run quicker, screens load faster; end-of-day processes finish sooner.

None of this requires new training, new workflows, or waiting for a future release. It’s the immediate return on moving to modern, purpose-built infrastructure.

Year One: AI Automation Starts Doing Real Work

Once the foundation is in place, Sierra’s AI capability, delivered through Aderant’s AI layer MADDI, starts automating work across the financial functions that consume the most manual staff time:

• Accounts Receivable (AR) — automated matching, exception flagging, and follow-up prioritization
• General Ledger (GL) — automated reconciliation and anomaly detection

Across these areas, Sierra ships MADDI features that reduce the manual, repetitive work historically absorbed by finance and accounting staff. This is the stage where Sierra stops being “the new version of Expert” and starts being a system that actively reduces headcount hours spent on manual financial processing.

Year Two: Decisions in Minutes, Not Days

Sierra’s unified analytics bring data from across the firm’s financial functions into a single, modern view — replacing the patchwork of exports, spreadsheets, and manual report-building that most firms rely on today.

The practical result: questions that used to take days to answer — pulling data from multiple systems, reconciling it, building a report, circulating it for review — get answered in minutes. Combined with a modernized user experience across the platform, this is the stage where Sierra shifts from “faster back office” to a real driver of how quickly leadership can act on what’s happening in the firm.

Year Three and Beyond: No More Waiting for the Next Release

Because Sierra is built on Stridyn, it isn’t a static release that ages the way on-prem software does. New modules and capabilities ship on the platform on an ongoing basis, and firms already on Sierra receive them as part of the platform — not as a separate upgrade project requiring its own budget cycle and migration.

This is the structural difference from the old upgrade model: instead of a multi-year gap between major releases followed by another disruptive migration, firms on Sierra sit on a platform that keeps advancing under them. The value curve that started on day one doesn’t plateau — it keeps extending.

Customer Proof: The Curve in Practice

Holland & Knight, Kostelanetz, and Rivkin Radler have each moved through these stages on Sierra, and their experience reflects the same pattern — infrastructure gains showing up immediately, followed by measurable operational improvements as AI automation and unified analytics come online.

“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.
