In general, ERP systems have a usability problem. When the software that runs your financials, inventory, purchasing, and operations is the system your team dreads opening, this is a huge problem. Acumatica has long been known for superior usability, and this trend accelerates even further with the introduction of the Modern UI.
Acumatica’s Modern UI is now generally available as of September 2025 with the 2025 R2 release. It is not a cosmetic refresh. It is a comprehensive redesign of how users interact with the platform, focused on making daily ERP work faster, cleaner, and more personal to each user’s role.
Below is where the Modern UI makes the most meaningful difference from a usability and quality-of-life standpoint.
The Classic UI was functional, but it was built for a different era. Fields were small and uniformly styled. Status indicators didn’t stand out. Finding what you needed on a busy screen meant scanning row after row of identically formatted data.
The Modern UI groups related fields into color-coded fieldsets, soft visual blocks that make it immediately clear where key information lives. Status fields are color-highlighted. Controls are larger, spacing is more generous, and the overall layout follows modern design conventions that reduce eye strain and cognitive fatigue.
This is not about aesthetics for its own sake. When critical data stands out at a glance instead of hiding in visual noise, people make fewer mistakes and work faster. That compounding effect matters when your team is in the system eight hours a day.
This is arguably the Modern UI’s strongest feature for day-to-day users. The new interface gives individuals real control over how their screens are organized, and none of it requires a support ticket or a customization project.
Users can:
Administrators get a separate layer of control through Screen Configuration Mode, where they can add, remove, or rearrange fields, including user-defined fields, and publish standardized layouts across roles. The key distinction: system-wide configurations and personal preferences coexist. An administrator can enforce a consistent baseline for the AP team while each clerk still maintains their own column widths and collapsed sections.
The practical impact is significant. An AP clerk processing invoices and a CFO reviewing financial summaries can look at the same system and see entirely different, role-appropriate views. All without either one disrupting the other.
Acumatica reports an average 10% speed improvement across the platform with the Modern UI. The new architecture loads screen components on demand rather than rendering everything at once, which means faster page loads and smoother navigation, especially on complex forms with many tabs and fields.
The filtering system has been completely rebuilt. The old filter tabs are replaced with a streamlined Filter List that includes quick search (just start typing), favorites that pin to the top, clearly marked shared filters, and a redesigned advanced filter editor that makes complex conditions easier to build and understand.
Early adopter data from implementation partners suggests the real-world impact is substantial: reports of 30% faster task completion and filtering improvements that cut search times by up to 70%. Even conservatively, those are meaningful minutes saved on tasks performed dozens of times daily.
The Classic UI was designed for desktop monitors. On a tablet, it was usable but compromised. On a phone, it was a struggle.
The Modern UI is fully responsive. Layouts adapt automatically to the device. Whether a 27-inch desktop monitor, a laptop, a tablet on a warehouse floor, or a phone at a job site. Fields reflow, tables adjust, and the interface remains clean and functional across screen sizes.
This matters most in industries where people are not at a desk all day. Construction managers approving change orders on-site, warehouse staff receiving inventory on the floor, sales reps pulling up customer history during a meeting — the Modern UI makes Acumatica genuinely usable in those contexts, not just technically accessible.
Small usability improvements compound over a workday. The Modern UI consolidates the old “Customization” and “Tools” menus into a single Settings menu on the form title bar. Lookup fields now display selected values as clickable links instead of pencil icons, giving users a consistent way to navigate to related records. Error rows in tables are highlighted across the entire row, not just flagged with a small icon.
Numeric values that exceed column width now display “#” characters instead of silently truncating, so users know immediately when they need to widen a column. File attachments have been modernized with improved integration for scanning and mobile uploads.
None of these changes are headline features. All of them reduce friction in ways that matter when the system is your primary work tool.
ERP training costs are real, and they do not end at go-live. Every new hire, every role change, every seasonal worker represents a training cycle. Complex, unintuitive interfaces extend those cycles and increase the error rate during ramp-up.
The Modern UI’s cleaner visual hierarchy, intuitive grouping, and personalization capabilities reduce the amount a new user needs to learn before becoming productive. Implementation partners have reported that training time has shortened from weeks to days in environments running the Modern UI, because users spend less time learning where things are and more time learning what things mean.
For organizations with high turnover in transactional roles or seasonal staffing needs, this reduction in ramp-up time has a direct cost benefit.
Acumatica designed the migration path with operational continuity in mind. Users can switch between the Modern UI and Classic UI on a screen-by-screen basis, so there is no forced cutover that disrupts daily work. Your existing workflows, data, business rules, and automations are unaffected.
The Classic UI is being phased out over future releases, but organizations adopting now have the advantage of transitioning at their own pace. Start with a few high-traffic screens, let users acclimate, gather feedback, and expand from there.
With nearly 900 screens already converted to the Modern UI, the coverage is broad enough for most organizations to run primarily on the new interface today.
From a practical evaluation standpoint, Acumatica’s Modern UI succeeds where many ERP interface updates fall short:
The Modern UI will not fix broken processes, incomplete master data, or poor adoption habits. No interface will. But for organizations already running Acumatica, or for those evaluating it, the Modern UI meaningfully raises the bar on what daily ERP interaction looks and feels like. And in a system your team uses every day, that quality-of-life improvement translates directly into productivity, accuracy, and user satisfaction.
