Is a web app right for you?
- You want to speed up a process in your business, like quotes, scheduling or customer contact.
- You want to give your customers their own place to sign in.
- You have an idea for a SaaS product and want to offer it online.
- Your users mostly work on a computer, or don't want to install anything.
Want to be in the App Store and Google Play too? Then we build an app alongside it, on the same backend.
Read about app developmentWhat the price depends on
A web app starts at €7,500. What yours costs mostly depends on these four things.
-
Screens and features
A simple client portal is done sooner than a full platform with scheduling, reports and notifications.
-
Users and permissions
One kind of user is simpler than customers, staff and admins who each have their own permissions.
-
Payments
Subscriptions, invoices or pay-per-use: each model works differently.
-
Integrations
Every connection to another service, like your accounting software or CRM, takes extra time.
After the intro call you get a quote with a fixed price. So you know where you stand before we start.
Work out what your project costsSee it first, then decide.
You don't have to build a complete app straight away. Start with a design, and pay for the build per demo.

App design
Your app's main screens, clickable on your own phone. So you know exactly what you'll get before you decide. If you don't like the design after two rounds of changes, you get your money back. Test it with users or show it to investors. If we build the app within six months, we deduct the design from the price.
-
Pay per demo
Apps, web apps and MVPs are paid per demo: after the demo of each part, you pay for that part. So you only pay for what you've seen. You may stop after any demo, and you take the code with you.
All prices exclude VAT.
What we build with
We build the front end with React and TypeScript. The backend runs on Firebase, or on a custom API in Python with FastAPI or Django.
From first call to launch
You always know where your project stands.

Questions about web apps
Question not listed? Email info@swivra.nl
What's the difference between a web app and a website?
On a website you read information. In a web app you do something: sign in, fill in data, schedule or pay. Think of a client portal, a dashboard or a booking system.
Does a web app work on my phone too?
Yes. The web app works on desktop, tablet and phone. If you later want an app in the stores as well, we build it on the same backend.
How long does it take?
Usually 4 to 10 weeks, depending on what the web app needs to do. The quote comes with a week-by-week plan. The quote states the date your web app goes live. If we go live late through our own fault, 2.5% of the price comes off for every week, up to 25%.
Where does my web app run?
Usually on Firebase and Google Cloud, with your data in Europe. Hosting is in your name and you pay the provider directly, with no markup from us.
What about the GDPR?
We store data in Europe and give each user access to only what they need. We help you work out which data you really need, so you don't keep more than necessary.
