Customer portal, configurator or SaaS built for you
Want to turn your expertise into a digital offering that customers and partners use directly? We develop your customer portal, configurator or SaaS product: integrated with your ERP, CRM and shop, prototype in a few weeks, and you own the source code.
- 80+ projects
- 5.0 on Google
- EU & GDPR first
- Initial consultation directly with the managing director – free & non-binding
Which digital product is right for you?
Whether your customers should handle orders and documents themselves, configure products online or use your software on a subscription: we build the product that fits your business model, not whatever the website builder happens to offer.
What your own digital product actually delivers
Your customers have long expected it: they google “your company name customer portal”, compare prices online and want to see the status rather than ask for it. Your own portal turns these expectations into measurable results.
How your digital product comes to life
No 80-page specification and no months without results. Every step has a tangible outcome, and after each step you decide whether to continue.
- 1
Initial consultation
30 minutes with the managing director: goal, target group, existing systems, business model. You get an honest assessment of whether the product will pay off and roughly what it will cost. Free and non-binding.
- 2
Concept & clickable prototype
Together with your specialists and selected customers, we clarify workflows, roles and interfaces and build a clickable prototype. That way you and your customers see the product before a single line of production code is written. Outcome: a roadmap with a cost framework.
- 3
First version in 4 to 8 weeks
We develop the core feature as an MVP with real data and real users: first the workflow that saves the most enquiries or brings in revenue fastest. You test with pilot customers, we measure and fine-tune.
- 4
Integration & go-live
Integration with ERP, CRM, shop, payment providers and specialist software, roles and permissions, data protection, hosting in the EU. Plus training for your team and a smooth rollout to your customers.

Operation & expansion
Monitoring, maintenance and support in live operation. Then the next features, prioritised by usage and customer feedback, until the portal has grown into a platform or a SaaS product.
AI writes code. We build software.
Thanks to wunderOS and our wunderFactory.
AI has opened up programming to everyone: anyone can put a prototype together today. Whether it turns into software that holds up in day-to-day operation is decided afterwards – in architecture, security, testing and maintenance over the years. That is exactly where prompting and real expertise part ways.
That is why we built our own operating system: wunderOS runs our company from sales to development. At its heart is the wunderFactory, where our AI agents, the wunderBots, build to the architecture rules, standards and tests from 20 years of software development – led by experienced software architects.
The result is software built noticeably faster and more affordably – in the quality you hire us for. We are AI experts and use that to get the best out of your project.
What you get out of it:
- More software for the same budget
The wunderBots handle the routine work. You pay for architecture, decisions and results – not for legwork.
- Live in weeks, not months
From the workshop to the first usable version, with changes after that in days. You see early on what works.
- Quality is built in, not bolted on
Tests, reviews and security checks run automatically in the wunderFactory with every change – not just when there is time.
- Architects, not prompters
The AI executes, we decide: data model, interfaces, operations. That way your software stays maintainable and extensible five years from now.
Bottom line: Bespoke software on terms that make sense for SMEs too – built with AI, with software architects accountable for it.
AI-generated.
Thank you very much!
I will get back to you as soon as possible!

A product that belongs to you and works with your systems
A customer portal is only as good as its integration. That’s why we don’t build an isolated solution next to your ERP and CRM, but a product that uses your existing data and that you can have developed further at any time, with or without us.
For us as a team from Austria, this is not an extra option but standard practice: EU & GDPR first.
- Integrated with ERP, CRM, shop and specialist software
Prices, availability, orders and documents come from your systems via interfaces (APIs). Your existing software stays; the portal complements it.
- You own the source code
Open, widely used technologies such as TypeScript, React, Next.js and Laravel, clearly documented. No per-user licence, no dependence on a website builder or a single developer.
- Roles, permissions and tenants
Every customer, dealer or partner sees only their own data. Multi-tenancy, approval levels and audit logging are part of the architecture from the start, not a later rebuild.
- Hosting in the EU, GDPR-compliant
Operation in the EU, on-premise or in your own cloud on request. We plan data processing agreements, the privacy policy and deletion concepts right from the start.

Frequently asked questions about customer portals, configurators and SaaS
Your question isn’t listed? We’ll answer it directly with the managing director in a free initial consultation.
How much does it cost to have a customer portal developed?
It depends on the scope, above all on the number of features and the systems to be integrated. At wunderwerk, a first customer portal with login, order status, documents and ERP integration can be built as an MVP in 4 to 8 weeks of development; configurators with complex pricing logic or a multi-tenant SaaS product take more. You receive a transparent cost framework before every step. Get an initial estimate with the cost calculator or in a free initial consultation.
How long does it take to develop a customer portal or SaaS product?
A clickable prototype is usually ready within a few days; wunderwerk develops a first usable version with the core feature in 4 to 8 weeks, depending on scope. After that, we expand the product in short iterations, with regular test versions and feedback from your pilot customers. A complete SaaS product with billing and tenants typically grows over several months, but is in use from the first version.
Buy customer portal software or have it custom-developed?
Off-the-shelf portals make sense if your processes are standard and you can live with per-user licence fees. Custom development pays off as soon as the portal needs to reflect your own products, pricing logic, roles and systems, or is to become a product in its own right. In the initial consultation, wunderwerk honestly assesses which route suits you, and recommends the standard option when it is enough. With custom development, you own the source code and there are no licence fees per customer.
What is a B2B customer portal and what should it include?
A B2B customer portal is a protected area where business customers, dealers or partners work with your company independently. Typical features are orders and repeat orders with customer-specific prices, order and delivery status, invoices, contracts, certificates and data sheets, service requests and complaints, as well as user management with roles per customer company. wunderwerk starts with the two or three features that save the most enquiries and builds from there.
Can the portal be integrated with our ERP, CRM or shop?
Yes. wunderwerk connects customer portals and configurators via interfaces (APIs) to ERP, CRM, shop, DMS and specialist software, so that prices, orders and documents are maintained in one place only. Your existing systems remain in place; the portal is the interface your customers use on top of them. If a legacy system lacks an interface, we find a way during the analysis, for example via database access or export/import.
What does it take to have a SaaS product developed?
Four things: a problem that many companies share, a workflow you know better than others, a first pilot customer and an architecture that securely separates multiple customers (tenants). wunderwerk adds subscription billing, a trial period, user management, monitoring and operation. Two of our SaaS products, a learning platform with over 30,000 users and a photovoltaic calculator with over 15,000 plans, have been running on a subscription model for years.
What is a product configurator and when is it worthwhile?
A product configurator lets customers put together variants, dimensions and options themselves and instantly shows price, delivery time and quote. It pays off as soon as your sales team spends a lot of time on individual quotes or customers in your shop struggle with the number of variants. wunderwerk develops configurators with pricing logic, variant rules and integration with shop and ERP. Find out more under Product configurator development.
Who owns the source code of the portal?
You do. wunderwerk develops with open, widely used technologies such as TypeScript, React, Next.js, PHP/Laravel and React Native and documents the software clearly. You pay no per-user licence and remain independent of individual developers or a website builder provider.
How secure is customer data in the portal? Is it GDPR-compliant?
Yes. wunderwerk hosts in the EU, on-premise or in your own cloud on request, and builds roles, permissions and tenant separation into the architecture from the start, so that every customer sees only their own data. We plan data processing agreements, audit logging, deletion concepts and the privacy policy as part of the project. For us as a team from Austria, EU & GDPR first is standard practice.
Can we have an existing portal or prototype developed further?
Yes, after a technical and commercial analysis. wunderwerk reviews code, architecture, security and the rights to the source code and shows whether the existing portal can be expanded or whether a new build is more economical. This applies to legacy software that has grown over the years as well as to prototypes created with website builders or AI tools such as Lovable.
Is there funding for a customer portal or SaaS project?
Yes, for many digitalisation projects such as customer portals, configurators and platforms there are suitable funding programmes, depending on country, region, company size and project. wunderwerk carries out an initial funding check with you and shows which options are available for your project. The easiest way is in a free initial consultation.
Why wunderwerk for a customer portal, configurator or SaaS?
Because for over 20 years we have been building digital products that are used every day by tens of thousands of users, and we run them ourselves on a subscription model. wunderwerk is a small, well-coordinated team of software architects, full-stack developers and AI engineers in Tyrol, Vienna and Berlin. You talk directly to the managing director, get concept, development and operation from a single source, and a product that belongs to you.
