Custom software or off-the-shelf: which pays off for you?
For many jobs there are good ready-made programs. A web app of your own only pays off once off-the-shelf software costs you more time than it saves.
Off-the-shelf software is enough if …
- your processes work like those of most firms in your sector.
- a ready-made program covers what matters, and the rest doesn’t hurt.
- you handle only a few clients or orders a week.
- nobody on your team retypes data by hand.
A custom web app pays off if …
- your team copies data back and forth between Excel, e-mail and bexio, the Swiss accounting software.
- you pay for three programs and none of them really fits.
- your clients keep calling to ask how things stand.
- the way you work is your edge and doesn’t fit any standard form.
If a ready-made program suits you better, I’ll tell you in our first call. And which one I’d pick in your place.
Typical web apps for SMEs
Four examples from everyday business.
Customer portal
Clients find everything themselves.
Example: An accounting firm: clients upload their receipts and see where their tax return stands. The ‘How far along are you?’ calls stop.

Booked and paid, without a phone call.
Example: A course provider: participants book online, pay straight away and move up from the waiting list when someone cancels.

Orders, planning or stock in one place.
Example: A joinery: orders, materials and the job schedule in one place. Everyone sees on their phone what’s on today and what’s still missing.

An instant estimate, a complete enquiry.
Example: An electrician: customers put together their own electric car charger. Instead of ‘Please call me back’, you receive a complete enquiry.

My work
Two web apps I built. Both in use.
VTAG and KnipVrij are my own products from the Netherlands. Sign-up, payment, waiting lists and scheduling: many SMEs need exactly that too.

Frequently asked questions
What businesses want to know before they start.
How much does it cost to have a web app built?
A customer portal starts at CHF 12'900.–, a booking and payment system at CHF 14'900.– and an MVP for founders at CHF 19'900.–, each excluding VAT. After our first call you get a fixed-price quote within 48 hours.
How long does development take?
The first version is live after 6 to 8 weeks: a customer portal after 6 weeks, a booking system after 6 to 8 weeks, an MVP after 8 weeks. The date is in the quote, backed by my delivery guarantee.
Do I own the code?
Yes. You get the code of your web app, all the data and every login. I reuse a few proven building blocks, such as the login, across several projects. For those you get a permanent, free and transferable licence. So you can carry on with another developer at any time.
What if I want to change something during the project?
Your feedback from the weekly previews is included in the fixed price, as long as it stays within the agreed scope. If you want something new, I tell you in writing beforehand what it costs and whether the date moves. You decide.
Where is my data stored?
On servers in Switzerland or the EU, your choice. I set up data protection in line with Swiss law (the revised Federal Act on Data Protection, FADP), including a data processing agreement.
What does it cost to run after launch?
Servers, updates, backups and monitoring cost from CHF 250.– per month, depending on the size of your web app. The amount is a separate line in the quote, so you know before we start what it adds each year.
