Legacy Business App UX Redesign in Amsterdam

The verdict in three sentences

A business app that requires 3 weeks of training is quietly expensive: data entry errors, dependency on veterans, and staff turnover that resets everything. In Amsterdam, a serious UX redesign costs EUR 30,000 to 75,000 and runs 8 to 16 weeks, often without touching the business engine. Realistic goals are measurable: training time cut in half and 30 % fewer clicks per routine task.

Diagnose before you redesign

The operations director of a regional transport company sees the symptoms: planners keep sticky notes with shortcuts, new hires call a colleague ten times a day, and creating a transport order takes 14 screens. Before any mockup, the UX audit measures the current state on 5 to 8 critical tasks: create an order, assign a driver, change a delivery slot, handle a claim, print a CMR consignment note.

Nielsen's rule still holds in 2026: 5 users uncover about 85 % of usability problems. With 8 participants split between experienced staff and newcomers, you cover both populations. Each session lasts 45 to 60 minutes, observed and timed.

2026 budget in Amsterdam

There are three levels of work. A priority screens redesign keeps the server code and redraws the key screens. A full front-end redesign rebuilds the whole interface with a design system. A deep redesign also reworks business workflows and part of the API. Dutch agency day rates sit roughly 20 to 25 % above western France.

These are 2026 ballpark figures for the Netherlands, excluding VAT. Some companies offset part of the cost through the WBSO R&D tax credit when the project includes genuine technical development; check eligibility with your adviser.

Roll out without disrupting operations

A transport company cannot stop operating for a tool change. The recommended method is a screen-by-screen cutover: old and new interfaces coexist on the same database, and each module first opens to a pilot group of 5 planners for one week. Feedback is handled within 48 hours. Experienced users keep a link to the old screen for one month, which greatly reduces resistance to change.

Mini case study

Sanne, operations director of a 180-employee logistics company near Schiphol, hires 12 planners a year. She chooses the full front-end redesign at EUR 50,000 over 12 weeks.

The math: training drops from 15 to 7.5 days, i.e. 7.5 days saved × 12 hires × EUR 300 daily cost (new hire salary plus mentor time) = EUR 27,000 a year. The 50 planners in post each save 2 min 30 on 30 orders a week, about 62 hours a week, 2,850 hours a year at EUR 40 an hour, the equivalent of EUR 114,000 of freed capacity. Even counting only a quarter of that gain, payback comes in under 12 months.

FAQ

Do we have to rewrite the app's server code?

Not necessarily. In 6 projects out of 10, the database and business logic stay in place and only the front end is rebuilt, which keeps the budget at EUR 30,000 to 50,000.

How many users should take part in testing?

8 participants are enough for a first round, with a second test of 5 people on the prototype. Plan about 1 hour per person per session.

How do we prove the gains to the board?

By measuring the same tasks before and after: time, clicks, errors and SUS score. A 6-metric table like the one above is enough to document the return.

Does the redesign improve accessibility?

Yes, if it targets WCAG 2.1 AA, which the European Accessibility Act makes increasingly expected: contrast, keyboard navigation, text sizing. The extra cost is 5 to 10 % of the budget if built in from the start.

What happens after delivery?

A quarterly improvement cycle of 2 to 4 days, i.e. EUR 2,000 to 4,000, lets you refine screens based on fresh usage data.
