ERP UX Redesign: How to Improve Your ERP Interface Without Replacing the System

Your ERP holds the data. Your team cannot find it. Every day, people in your business waste hours clicking through screens, exporting to Excel, and re-keying information into spreadsheets. The system works. The interface does not.

This is not a problem with your ERP vendor. It is a structural consequence of how enterprise software is built. ERPs are designed to store and process data reliably. The user interface is an afterthought — a generic layer that prioritises completeness over task completion. The result is a system that asks your staff to think like database administrators when they should be doing their jobs.

The good news: you can fix the interface without replacing the ERP. An interface layer sits between your staff and the ERP, surfaces exactly what each role needs, and connects to your existing system through its API. No data migration. No parallel running. No months of downtime.

This article covers why ERP interfaces are bad, what a proper UX redesign looks like, and how to measure the return on investment.

1. The Real Cost of Bad ERP UX

The numbers are worse than most directors realise. A 2024 user experience survey across ERP platforms found that 68 per cent of users rate their ERP navigation as poor or very poor. Fifty-four per cent describe their dashboards as cluttered and unhelpful. These are not edge cases. They are the majority.

The cost translates directly into labour. When a system is hard to use, people build workarounds. They export data to Excel, maintain their own spreadsheets, create paper notes, and ask colleagues who know where to look. One study tracked the time lost to poor ERP UX across a 150-person manufacturing firm and found the equivalent of 2.3 full-time positions spent on navigation and data retrieval alone. Spreadsheet workarounds across the supply chain cost between 3 and 5 per cent of annual revenue for many mid-size manufacturers.

Then there is the frustration cost. Staff who fight their tools every day are less engaged, harder to retain, and slower to train. New starters in a warehouse or customer service role typically take four to six weeks to become independently effective on a typical ERP interface. That onboarding delay has a direct cost in productivity and supervision time.

2. The “Infinite Form Syndrome”

Most ERP screens are forms. A sales order screen has fields for customer reference, delivery address, line items, discount codes, tax codes, delivery dates, carrier, special instructions, internal notes, and twenty other fields the user does not need to see. The form presents all of them at once because someone, somewhere, might need each field on some occasion.

This is the “Infinite Form Syndrome.” The interface designer could not decide what to prioritise, so they showed everything. The burden shifts to the user to filter through noise and find what matters for the task at hand.

The SAUCO analysis — a structured activity audit of user interaction costs — demonstrates the financial impact. Consider a typical sales order processing workflow in a UK distribution business:

• Page load and navigation to Sales module: 8 seconds
• Select customer from list: 12 seconds
• Scroll past 18 unused fields to reach line items: 6 seconds
• Enter line item data across 4 screens (product, quantity, price, delivery): 45 seconds
• Apply discount in a separate popup: 14 seconds
• Submit and confirm: 5 seconds

The total is approximately 90 seconds per order for a task that should take 20. If your business handles 100 orders per day across a department, the SAUCO analysis yields roughly 100 hours per month in wasted interaction time. At a blended fully-loaded cost of £22 per hour for order processing staff, that is £26,400 per year — per department. For a business with five departments touching the same system (sales, warehouse, purchasing, finance, customer service), the annual waste approaches £137,000.

And that is just click time. It does not account for error correction, rework, or the cognitive load of navigating an interface that fights you.

3. Why ERP Interfaces Are So Bad

There are five structural reasons ERP interfaces underperform:

Architectural debt

Most ERP products were first built in the late 1990s or early 2000s. Their UI layers were constructed when web standards were primitive, screen resolutions were low, and the dominant interaction model was the data entry form. The underlying data model is sophisticated; the UI was bolted on and has been patched repeatedly ever since. Each update adds another layer of complexity. Nobody rebuilds from scratch because the cost and risk are prohibitive.

Designed for data entry, not task completion

ERP interfaces are built around database entities: Sales Order, Purchase Order, Item Card, Customer Card. They are not built around user tasks: take an order, check stock, release a pick, update a delivery date. The user must translate their task into the ERP’s entity model before they can do anything. This translation step is the source of most navigation complexity.

One-size-fits-all Role Centres

Modern ERPs like Dynamics 365 Business Central and Sage 200 offer Role Centres. In theory, these give each user a tailored landing page. In practice, configuring them usefully requires significant effort, and most deployments ship with a generic layout. The warehouse manager, the credit controller, and the customer service lead all see essentially the same interface, just with different tiles. None of them see the information that matters most to their role.

Feature bloat

ERP vendors compete on features. Every release adds new functionality. Very little is removed. The interface grows denser with each version. What started as a usable system for a discrete set of tasks becomes a bloated monolith where the most common actions are buried behind menus, sub-menus, and configuration options that the user never touches.

Vendor lock-in to legacy UX paradigms

ERP vendors are constrained by their existing customer base. Radical UI changes risk alienating long-term users who have built muscle memory around the current interface. So vendors make incremental changes. The interface improves at the margins but never fundamentally restructures around how people actually work.

4. The UX Redesign Approach for ERP

A genuine UX redesign for an ERP system does not reskin the interface. It restructures how information and actions surface for each role. There are five principles:

Role-based design

Each role in the business gets an interface designed around their specific tasks and decisions. The warehouse operative sees pick lists, stock checks, and dispatch confirmations. The customer service agent sees order status, customer history, and delivery tracking. The managing director sees a dashboard of KPIs with drill-down. No shared interface. No scrolling past irrelevant fields. Each role’s screen is built from scratch around what that person needs.

Task-oriented workflows

Instead of navigating around database entities, the user executes a task. “Take an order” is one screen, one flow, done. “Check stock availability” is one click. The ERP does the translation in the background. The user never sees a Customer Card or a Sales Order header unless they specifically need it.

Progressive disclosure

Show the essential fields by default. Surface secondary fields when the user needs them. Hide the rest. A sales order entry form that currently shows 28 fields can show five on first load, then expand as the user progresses through the workflow. The data is still captured. The user sees only what matters at each stage.

Mobile-first where appropriate

Warehouse staff do not sit at desks. They walk aisles with handheld scanners. Field sales staff visit customer sites. Shop floor supervisors move between machines. For these roles, an interface designed for a mobile screen is not a convenience; it is a requirement. A genuine mobile-first approach redesigns the workflow for the device, not just shrinks the desktop layout.

Real-time data, not batch exports

Every interface element pulls live data from the ERP API. No nightly exports, no CSV uploads, no stale data windows. The dashboard shows stock levels as they stand, order status as it updates, delivery schedules as they change. This eliminates the trust gap that drives spreadsheet workarounds.

5. Architecture: Interface Layer Over ERP

This is how the architecture works. A purpose-built interface layer sits between your staff and the ERP, communicating through the ERP’s API. The ERP remains the system of record. No data is duplicated. No migration is required.

The interface layer connects to the ERP via its published API. Authentication uses whatever identity provider you already run (Microsoft Entra ID, Okta, or direct ERP credentials). The layer renders in any modern browser and on mobile devices. It does not modify the ERP, does not require an ERP upgrade, and does not put your database at risk.

6. Specific UX Improvements Possible

Here is what a well-designed interface layer can achieve:

Reduce clicks from 12 to 2

A common customer service workflow: a customer calls to check order status. In the native ERP, the agent navigates Sales Orders, finds the right order (which may require knowing the order number or the customer account code), opens it, clicks to Posted Shipments, checks the carrier reference, then opens the carrier’s tracking page. That is eight to twelve clicks and up to four minutes.

In a redesigned interface, the agent types the customer name or order number into a search bar. The interface shows a live card: order status, tracking number, carrier link, and estimated delivery date. Two clicks. Fifteen seconds.

Role-specific dashboards

A management dashboard shows cash position, gross margin, order book ageing, and delivery performance by week. A warehouse supervisor dashboard shows pick queue depth, backorder volume, and carrier cutoff times. A credit controller dashboard shows overdue accounts, credit hold warnings, and payment reconciliation status. Each role gets the data that drives their decisions, no more.

Real-time data everywhere

Stock levels update as warehouse staff process picks. Order statuses update as goods are dispatched. Customer credit limits update as payments are reconciled. The interface polls the ERP API automatically — no manual refresh, no stale data, no uncertainty about whether the screen shows current information.

Task-oriented navigation

Instead of “Sales Orders → All Sales Orders → Find Order → Open Order,” the interface presents a search bar and a set of task buttons: New Order, Check Stock, Find Order, Customer Lookup. Each button launches a purpose-built flow. The user never sees the ERP’s menu structure.

Mobile access for warehouse and field staff

A warehouse operative on a tablet sees a pick-by-pick list. Completing a pick updates the ERP in real time. No paper, no back-to-the-office data entry, no lag between what has been picked and what the system thinks is available. The same interface works on a mobile phone for field sales staff who need stock checks and order placement at customer sites.

Customer self-service portal

Customers can check order status, view invoices, download proof of delivery, raise returns, and check account balances without calling your staff. The portal is a branded interface layer over the same ERP API. It reduces inbound call volume, improves customer satisfaction, and eliminates the staff overhead of answering routine queries.

7. Measuring the Improvement

Before you redesign, establish baseline metrics. After you deploy, measure the same metrics. The difference is your return on investment.

Click audit

Identify the twenty most common workflows in your business (take order, check stock, process dispatch, check credit status, etc.). Count the number of clicks, key presses, and page loads in the current interface for each workflow. Target: reduce by 70 per cent or more.

Time-per-task tracking

Time a sample of users performing each workflow in the current interface. Measure the same users performing the same tasks in the new interface. Average reduction across a UK manufacturing client of ours was 82 per cent for order status queries and 67 per cent for new order entry.

Form abandonment rates

Measure how many tasks are started but not completed within the same session. High abandonment rates indicate an interface that frustrates users into giving up. Track this before and after the redesign.

Spreadsheet audit

Count the number of spreadsheets in your business that contain data that also exists in the ERP. Each one represents a trust failure: someone does not trust the interface to surface the data they need. Target: eliminate all of them.

User satisfaction score

Survey your staff on a scale of 1 to 10: “How easy is it to do your job using the ERP interface?” A score of 4 or below is a clear signal for intervention. A score of 7 or above means the interface is supporting rather than hindering.

8. Real-World Before and After

Here are two examples from our work with manufacturing and distribution businesses running mid-market ERPs.

Sage 200: Flat list views to gauge dashboard

Before: The sales team used a flat Sage 200 list of open sales orders, sorted by date. To answer a customer query about delivery status, they clicked into each order, navigated to the delivery tab, cross-referenced the carrier reference, and switched to the carrier website. Average time per query: 3 minutes 45 seconds. With 30 to 40 queries per day, the team spent over two hours per day on information retrieval.

After: A role-specific dashboard replaced the list view. The dashboard shows open orders as a gauge of total value by status (confirmed, picked, dispatched, delivered). Clicking a segment shows the orders behind it. Each order card surfaces the key details: delivery date, carrier, tracking link, and any holds. Average time per query: 35 seconds. The team recovered 1.5 hours per person per day.

OrderWise: Grid views to live operations dashboard

Before: The warehouse team worked through OrderWise grid views. Each order appeared as a row in a table. Status was indicated by a code. Picking instructions were accessed through nested menus. The system did not refresh automatically; staff hit F5 to check for new orders.

After: A live operations dashboard shows pick-ready orders as cards, colour-coded by urgency. Each card shows the customer, line count, weight, and a “Pick Now” button that launches a purpose-built pick workflow on a tablet. Completed picks update the ERP in real time. The warehouse supervisor sees a live queue depth gauge and can predict whether the afternoon pick wave will complete before the carrier cutoff. Supervisors can re-prioritise with a simple drag-and-drop. New orders appear automatically within 30 seconds of being created in the ERP.

9. How to Scope a UX Redesign Project

A well-scoped ERP interface redesign project follows a predictable structure. Do not start with a specification document that tries to define every screen. Start with a discovery sprint.

Discovery sprint (2 to 5 days)

• Walk the floor. Spend time with each user group. Watch them use the ERP. Ask them to show you what frustrates them. Observe the workarounds they have built. The workarounds are the specification.
• API audit. Map the ERP’s API to confirm it exposes the entities and fields needed for each role’s interface. For most modern ERPs (Dynamics 365 BC, Sage 200, OrderWise, SAP B1, NetSuite), the API coverage is sufficient. For older systems, there may be gaps that require alternative approaches.
• Wireframe the top three workflows. Design the interface for the three highest-value tasks: order status, stock check, and order entry. Validate with users before any development starts.
• Estimate. Fixed-price proposal based on the number of roles, the complexity of workflows, and the depth of API integration needed.

Build phase (4 to 12 weeks)

• API integration and authentication setup
• Role-specific dashboard build
• Workflow implementation
• User acceptance testing with a pilot group
• Iteration based on feedback

Rollout phase (2 to 4 weeks)

• Pilot group goes live
• Measure baseline metrics vs new interface
• Ripple to remaining teams
• Training: 30 minutes per user (the interface should require minimal training)

The total timeline from discovery sprint to full rollout is typically 8 to 16 weeks. No parallel running with the ERP. No data migration. No business downtime.

10. Frequently Asked Questions

Does an interface layer affect ERP performance?

No. The interface layer makes API calls to the ERP, which the ERP is designed to handle. A well-implemented layer adds negligible load — typically equivalent to a few extra concurrent users. Response time depends on the ERP’s API speed, not on the interface layer itself. If your ERP already performs well for its native UI, it will perform identically for the interface layer.

What if my ERP does not have a good API?

Most modern ERPs do. Dynamics 365 Business Central, Sage 200, OrderWise, NetSuite, SAP Business One, and Epicor all expose REST APIs with sufficient coverage for interface layer development. For older systems, there are workarounds: direct database views (read-only), ODATA connectors, or middleware. We assess the API quality during the discovery sprint and flag any limitations before build.

Will the interface layer break when the ERP updates?

The interface layer depends on the ERP’s API, which is versioned and stable. An ERP update that changes the API surface is rare and typically announced well in advance. When it does happen, the interface layer updates independently of the ERP — no monolithic bi-annual upgrade cycle, no regression testing on the entire system. The vast majority of ERP updates have zero impact on a well-built interface layer.

How is this different from Power BI or reporting tools?

Power BI and similar tools are great for analysis and reporting. They are not designed for task completion. An interface layer handles transactional workflows: entering orders, processing picks, updating delivery dates, creating returns. Power BI cannot write data back to the ERP. An interface layer can. They complement each other: Power BI for analysis, the interface layer for daily operations.

Can we build the interface layer ourselves?

You can, but be realistic about the effort. You need front-end development capability (React, Vue, or similar), API integration experience with your specific ERP, authentication setup (OAuth 2.0 or SAML), and ongoing maintenance. The core question is whether this is a priority for your internal development team or a distraction from your primary business systems. Most manufacturing and distribution SMEs do not have the spare front-end capacity to do it properly in a reasonable timeframe.

Does the interface layer replace the ERP UI entirely?

It depends on the role. For most operational staff (customer service, warehouse, purchasing, sales), the interface layer can become their primary working environment. For super-users and administrators who need access to ERP configuration, advanced reporting, or system administration, the native ERP UI remains available. The two coexist. Users pick the interface that suits their task.

What about security?

The interface layer authenticates through the same identity provider as the ERP (typically Microsoft Entra ID or the ERP’s own user directory). Role-based access control restricts what each user can see and do. The layer never stores ERP credentials or sensitive data beyond what is needed for the current session. API calls are made server-side, so the ERP’s database is never directly exposed to a browser or mobile device.

How much does a typical project cost?

A complete interface layer for three to five roles (customer service, warehouse, management, sales, purchasing) typically costs between £25,000 and £60,000, depending on workflow complexity and the number of integrations required. Compare that to an ERP replacement project, which runs £100,000 to £500,000+ and takes six to eighteen months. The interface layer pays for itself in reduced labour waste within six to twelve months at most businesses.
