KUIPERBook a callA low price isn't our pitch, it's a consequence. We keep the quality of a European agency by cutting the costs that don't serve your product.
A poorly designed $3,000 app costs $12,000 to fix. We charge for a serious methodology: business-rules analysis, clean architecture, tested and documented code, a stable team. You're paying for a system that lasts, not a throwaway prototype.
Fully loaded monthly cost (salary, contributions, office).
| Suisse | 15 000 CHF /month |
| Allemagne | 8 500 EUR /month |
| Italie | 6 000 EUR /month |

Sources (2025): levels.fyi · Glassdoor · StepStone · SalaryExpert · WeLoveDevs. Employer cost = senior gross salary + employer charges (CH ~17%, DE ~20%, IT ~30%, FR ~43%), office included. Indicative, rounded figures.
Your system built by a dedicated team: a project manager + a senior full stack developer, starting at $6,000/month. That's our floor, and it's non-negotiable, it's the price of work we won't have to redo. Every team includes the project manager: we don't rent out lone developers, we deliver managed systems.
Scale the team to your velocity:
| Mid-level developer | 2 000 $ /month |
| Senior developer | 3 000 $ /month |
| Expert / Technical lead | 5 000 $ /month |
| Mobile (Flutter) | +$500 on the profile |
Based on 20 working days. Adjustable at the end of each month. Juniors aren't sold on their own: they work on our Modules, supervised by a senior.
Always a project manager, never below the $6,000/month floor. Adjustable at the end of each month, indicative estimate.
Daily check-in with your team, written weekly report, direct access to the project manager (reply within 24h), a demo every week.
Ownership (Studio) : your business rules belong to you, fully and exclusively. They will never be replicated for another client. You're buying your competitive edge; it stays yours.
| Single-site | 2-5 sites (+45%) | |
|---|---|---|
| Inventory | 18 000 $ | 26 000 $ |
| CRM | 22 000 $ | 32 000 $ |
| POS | 35 000 $ | 51 000 $ |
| ERP | 40 000 $ | 58 000 $ |
Beyond 5 sites or multi-company: on scoping only.
Scoped deployment: release in the very first week, one month of setup and testing, one month of running-in with your feedback. Customization (~25%): your colors, your fields, your flows, no major business rules.
Ownership (Modules) : you own your instance and your data; the shared core (~75%) stays with Kuiper. Need exclusivity on your business rules? That's the Studio.
| Migration of your data (one source, usable formats) | 3 500 $ flat fee |
| Complex migration (multiple systems) | from 3 500 $, quoted at scoping |
| Light integration (accounting, emailing…) | 2 000 $ |
| Serious integration | 4 000 $ |
| Heavy integration (API, e-commerce, logistics) | 6 000 $ |
No surprise line item mid-project: anything outside the scope is quoted separately, before, never after.
Software that belongs to you. Your data lives on your server, no one sees it, analyzes it, or resells it. And you can cut off whenever you want: as soon as the system suits you and stops evolving, you stop paying for development. It stays yours, fully functional. An investment, not a rental.
Maintenance: never forced, always clear
| Monitoring only | 300 $ /month | Surveillance and alerts |
| Maintenance | 400-500 $ /month | Fixes, field additions, monitoring included |
| Maintenance + dedicated support | 500 $ /month | + small changes, a dedicated point of contact |
With it, stability is our responsibility. Without it, it becomes your teams', teams we'll have trained. It's a choice, not a leash: the only truly unavoidable cost is your server.
A 2-minute estimate on the simulator, or a direct scoping call, free, no commitment, and you leave with an honest opinion even if it's not with us.
