Which digital product is right for you?

wunderwerk builds four kinds of digital product: customer portals for self-service, product configurators for quotes, SaaS products on subscription and platforms that connect several sides. Which one fits depends on whether your customers should handle orders and documents themselves, configure products online or use your software on a subscription.

Customer portal & self-service

“Our customers call us about every invoice and every delivery status.”

A B2B customer portal where customers place orders, track jobs, download invoices, contracts and certificates and submit service requests. Around the clock, with your data from ERP and CRM, without endless email ping-pong.

  • B2B customer portal
  • Self-service
  • Dealer portal

Product configurator & quotes

“Every quote takes hours because every product is different.”

Customers put together variants, dimensions and options themselves, see price and delivery time instantly and receive the quote as a PDF or straight in their shopping basket. Pricing logic and variant rules stay with your company, not in your sales team’s heads.

  • Product configurator
  • Quote configurator
  • CPQ

SaaS product on subscription

“Other companies could use our in-house tool too.”

Your expertise becomes a software product that customers subscribe to monthly or annually: multi-tenant, with a trial period, billing and user management. A second revenue stream alongside your core business that grows with every customer.

  • SaaS development
  • Subscription model
  • Multi-instance

Platform & marketplace

“We want to bring suppliers, partners and customers together in one place.”

A web platform that connects several sides: partners, dealers, members or service providers with your customers. With roles and permissions, onboarding, payments and interfaces to the systems everyone involved already uses.

  • Platform development
  • Marketplace
  • Partner portal

What does your own customer portal actually deliver?

Your own customer portal takes load off your back office, accepts orders and enquiries around the clock and keeps customers close, because status, documents and order history sit in one place. 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.

Fewer queries for your back office

Delivery status, invoice copies, contract data, certificates: what customers ask for by phone and email today, they fetch themselves in the portal. Your team gains time for the cases that need a human.

Orders and quotes around the clock

Repeat orders, configurations and quote requests keep coming in during evenings and weekends, with prices, availability and terms straight from your ERP.

A new revenue stream with a subscription model

A SaaS product or a portal with premium features brings predictable, recurring revenue that grows with every customer, instead of starting from scratch with every project.

Customers who stay

Customers who keep their data, order history and documents in your portal won’t switch so easily over a few percent price difference. The portal becomes part of how they work with you every day.

Clean data without double entry

What customers enter in the portal goes straight into your ERP, CRM or ticket system. No copying from emails, no typos from retyping, no Excel list on the side.

Ready for AI agents

Your own product with clean data and interfaces is the foundation on which AI agents can later answer enquiries, prepare quotes and take over workflows. Find out more in our AI consulting.

How is your customer portal built?

wunderwerk builds a customer portal in five steps: initial consultation, concept with a clickable prototype, first version in 4 to 8 weeks, integration and go-live, then operation and expansion. Every step has a tangible outcome and is commissioned separately; after each step you decide whether to continue. No 80-page specification, no months without results.

  1. 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. 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. 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. 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.

  5. 5

    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.

AI-generated

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.

Integrated with your ERP, CRM and shop

wunderwerk doesn’t build customer portals as isolated solutions next to your ERP and CRM; it connects them to your existing systems via interfaces (APIs), so prices, orders and documents are maintained in one place only. A customer portal is only as good as its integration.

For us as a team from Austria, hosting in the EU 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.

  • Open technologies, clearly documented

    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.

We had the wunderworkers develop bespoke industrial software for creating recipes for a highly sensitive industrial process.

The collaboration was extremely professional from the outset: the team quickly understood our complex requirements, implemented them precisely and always paid close attention to maximum reliability and security. I would particularly like to highlight their technical know-how, clean documentation and fast response times for questions or change requests.

The recipe editor is now running in several plants in Sweden, Italy and the Czech Republic.

The software runs reliably, is intuitive to use and our customers are completely satisfied. We can recommend wunderwerk without reservation!

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?

The cost of a customer portal depends mainly on the number of features and the systems it has to connect to; wunderwerk gives you a transparent cost framework before every step. 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 commission the workshop, the MVP and ongoing operation separately, and a custom build carries no per-user licence fees. Get an initial estimate with the cost calculator or in a free initial consultation.

How long does it take to develop a customer portal?

wunderwerk develops a first usable version of a customer portal with its core feature in 4 to 8 weeks, depending on scope; a clickable prototype is usually ready within a few days. After that, we expand the portal 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 customer portal software makes sense if your processes are standard and you can live with per-user licence fees; a custom-built portal pays off as soon as it 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 gives you an honest view of which route suits you, and recommends the off-the-shelf option when it is enough. With custom development, 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 on their own. 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.

How secure is customer data in the portal? Is it GDPR-compliant?

Yes. wunderwerk hosts customer portals 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. See secure software development for how wunderwerk builds security in from the start.

Who looks after the portal after go-live, and what technology is it built with?

After go-live, wunderwerk takes care of operation, monitoring, maintenance and support, and keeps developing the customer portal based on usage and customer feedback. It is built with open, widely used technologies such as TypeScript, React, Next.js and Laravel, clearly documented, so the portal does not depend on a website builder or a single developer. Clients who have worked with us for more than ten years show that our software keeps running for years.

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.
