Do you want to find out whether people need your idea, or show an investor how it will work? I will tailor the scope to that goal and agree a fixed price and timeline with you before starting.

All-in
€3,000–5,250net
3–4 weeks
An MVP, a full website and a brand system — ready for conversations with customers or investors.
→Everything in the MVP package
→A full website instead of the landing page
→A visual and communication system for the brand
→A product presentation, materials and guidance for future use
I will design and build your website as part of a coherent brand. I will define its voice and visual direction, then give you materials and guidance to keep communicating consistently — on your website, on social media and in your sales materials.
You can commission a standalone website with a brand system. I will agree its scope and price with you separately.
This is what the tool I would build for your team looks like: scattered files go in, and the result waits for your approval.
Example, made-up data
Example: 48 invoices, receipts and messages from March go into the bookkeeping assistant. It prepares 46 entries and leaves 2 to clarify. Anna, the accountant, checks them and approves.

What you get
During a first test or presentation, you want to focus on the idea. I will take care of a professional appearance, clear interactions and testing the core scenario before handover.
In MVP: an app and a landing page
I will design and build the core app flow and a landing page — a single page that explains the idea and directs people to try it or get in touch. I will agree the exact scope with you before starting.
A working version every week
I will show progress in the app every week. You will see what works and share your feedback.
Code, accounts and documentation
After handover, the code, accounts and documentation stay with you. You can continue development with another builder too.
In All-in: a full website and brand system
I will replace the landing page with a full website. I will develop a visual and communication system for the brand and a product presentation, then hand over materials and usage guidance to keep future communication consistent. I will agree the website scope with you before starting.
