The verdict in three sentences
If a large share of your teams bypass your business app with Excel, a UX redesign costs far less than a rewrite: in Copenhagen in 2026, budget 30,000 to 55,000 EUR for audit, user testing and interface redesign (5,000 to 9,000 EUR for the audit plus 18,000 to 35,000 EUR for the redesign with a Bordeaux team). Total timeline is 10 to 14 weeks, with a design system delivered so future changes stay consistent. Typical gains are 35% shorter task time and support tickets cut in half.
Diagnose before you redesign
Going back to Excel is rarely a whim. It usually signals cluttered screens, repeated data entry, missing exports or slow long lists. The audit proves it with data rather than impressions.
| Audit method | What it measures | Copenhagen cost (2026 estimate) | Bordeaux team cost | Duration |
|---|---|---|---|---|
| Usage analysis (logs, analytics) | Abandoned screens, time per task | 1,800 to 2,500 EUR | 1,000 to 1,500 EUR | 1 week |
| User interviews (6 to 8 people) | Pain points, workarounds, real needs | 2,500 to 4,000 EUR | 1,500 to 2,500 EUR | 1 week |
| Moderated usability tests (5 to 6 key tasks) | Success rate, errors, time | 3,500 to 5,500 EUR | 2,000 to 3,500 EUR | 1.5 weeks |
| Heuristic and WCAG accessibility audit | Best-practice gaps, contrast, keyboard | 1,500 to 2,500 EUR | 800 to 1,500 EUR | 0.5 week |
| Readout and prioritization | Costed action plan per screen | Included | Included | 2 days |
Five tested users are enough to spot about 80% of an interface's major problems. For an app used by several departments (finance, logistics, sales), plan 5 testers per profile.
Redesign budget by scope
| Scope | Content | Copenhagen budget | Bordeaux team budget | Timeline |
|---|---|---|---|---|
| Targeted redesign | 5 to 8 critical screens, mockups, front-end build | 25,000 EUR | 18,000 EUR | 6 weeks |
| Standard redesign | 12 to 20 screens, basic design system, build | 36,000 EUR | 26,000 EUR | 8 weeks |
| Full redesign | 25 to 40 screens, documented design system, AA accessibility | 48,000 EUR | 35,000 EUR | 10 weeks |
| Full application rewrite | New back end and front end | 120,000 to 220,000 EUR | 80,000 to 150,000 EUR | 6 to 9 months |
| Training and change management | Workshops, guides, internal champions | 3,000 to 6,000 EUR | 2,000 to 4,000 EUR | 2 weeks |
The redesign keeps the existing back end when it is sound. The front end is rebuilt screen by screen, allowing gradual releases without blocking teams.
What the redesign changes in the numbers
| Indicator | Before redesign | After redesign (2026 estimate) |
|---|---|---|
| Users back on Excel | 40% | 8% |
| Average time to enter an order | 6 min 30 | 4 min 15 (−35%) |
| Support tickets per month | 120 | 60 (−50%) |
| Entry errors corrected afterwards | 9% of records | 3% of records |
| Onboarding time for a new hire | 3 days | 1 day |
| Satisfaction score (SUS) | 52 out of 100 | 76 out of 100 |
Mini case study
Mette, CIO of a food distributor in Copenhagen (90 users of the order management app), runs an audit and a standard redesign for 46,000 EUR in total. Each user enters about 25 orders a day: saving 2 min 15 per order frees about 56 minutes per person per day. Across 90 users and 210 days, that is about 17,600 hours, of which she conservatively counts only 20% as real gain, or 3,500 hours at 55 EUR loaded cost: 192,500 EUR a year. With 60 fewer tickets a month at 35 EUR each, she adds 25,200 EUR. The redesign pays back in under 3 months.

FAQ
How much does a business app UX redesign cost in Copenhagen in 2026?
Budget 30,000 to 55,000 EUR for audit and redesign together, or 23,000 to 44,000 EUR with a Bordeaux team. The full project takes 10 to 14 weeks.
Do you have to rewrite the app to improve adoption?
Rarely: if the back end works, a front-end redesign costs 3 to 5 times less than a 120,000 to 220,000 EUR rewrite. The audit settles the question.
How many users should be tested?
Five per job profile detect about 80% of major problems. A session lasts 45 to 60 minutes per person.
What is the delivered design system for?
It groups components, colours, form and accessibility rules. New screens are then built 30 to 40% faster and stay consistent.
How do you measure the adoption gain?
Usage rate, time per task, support tickets and SUS score are measured before and after. A dashboard tracked for 3 months after release validates the result.
