Product Configurator Software

kaliber5 is focused on 3D product configurator and modern custom made software solutions.

Product configurator

Product Configurator

A major trend in the economy is the digitization of business processes. Quotation and product configurators can become an integral part of the value chain. kaliber5 is dedicated precisely to this special topic and has designed and developed individual product configurators for the B2B and B2C market for more than 10 years. Special attention is paid to the following points:


Depending on the target group, customers, distributors and technicians have different previous knowledge and other requirements for a configurator. In any case, the operation must be intuitive and simple, so that even inexperienced users can quickly find their way around.

3D Visualizations

The immediate visual feedback of high-quality 3D product images makes the configuration an experience for the user. Here, images and videos can be created in advance or calculated and displayed in real time. But in any case, the use of plugins is not required.


Not all combinations can be implemented in practice. In some cases, quite complex mathematical and physical rules can be specified here. These must be taken into account in the application, so that the user cannot put together an invalid configuration when using it.


Since only individual tailor-made solutions are implemented, connections are possible to all interfaces, as well as shop systems.

User Experience

Successful software is characterized by a particularly simple and fun usability. A speciality of our experienced team of UX designers, software architects and programmers is to design software in such a way that it ensures the highest level of user experience. To do this, we integrate various accepted methods into our workflows, which ensure a continuous improvement in quality.


We prefer to develop agile software with the Scrum Framework. This creates solutions that meet real user needs.

User Centered

From individual user stories to mockups and on to the finished product, we always place the future user at the centre of all decision-making processes.


Quality is our first aim, and so we always test what we do. From the inside (automated software tests) as well as from the outside (usability tests).


We love technology. But it always has to serve a purpose. The success of your project.

HTML5 based software

We love modern HTML5 SPA front ends with ember.js, our preferred framework for ambitious web applications. No installation, no plugins. Open the browser and get started. It works. Anywhere.

web based Desktop Software

Previously, the web went like this: Click, load, wait. Click, load, wait. Today, the web goes like this: Click and it's there immediately. We say that web applications feel like desktop software. Fast. Interactive. Animated. Real time.

Responsive Design

Whether desktop, tablet or smartphone. Mouse or touch. Portrait or landscape. We develop software that works everywhere.

State of the art

Modern technology is a passion of ours. Whether the latest craze or already proven. We are always looking for the best solution for each individual problem. But always State of the art.

Open and extendable

Only dead software is completed. We develop software so that it can be adapted and extended to new requirements at any time. Whether an extension of your configurable product or an interface to your new ERP is pending, we are and will remain by your side.

Open Source

We develop new software based on stable, proven and in each case, leading open source software. For maximum effectiveness and cost efficiency. Of course, you will receive the source code of your software project exclusively.

What others are saying

  • Before starting the project, we were very worried about whether our new partner would understand our products and their difficult mathematical relationships. And whether it would be possible to create an attractive and easy-to-use software from dry material. Fortunately, our worries were unfounded.

  • For me, having a personal and reliable cooperation is very important. Nor do I like it when our partners wildly throw about technical terms. The skill is more in how to quickly and easily create working software together.

The Local Water


[ more ]

The Local Water wants to revolutionize nothing less than the process of our water supply. The centerpiece is innovative and certified water filters, which make ordinary tap water the best and purest drinking water, guaranteed free of bacteria, pesticides, drug residues, heavy metals, etc. This is good for the customers, who get the best drinking water, save money and no longer have to carry crates. But it is also good for the environment, because the complex production and the unnecessary consumption of plastic bottles will be reduced, as well as their transport by truck.

For this innovative startup, kaliber5 has a significant responsibility in all areas of the company, from brand building and the marketing and sales concept to digital implementation in design and programming.

The latter was particularly elaborate and sophisticated. Due to the individual requirements and processes, the e-commerce platform as an API-based back-end was developed completely individually, based on the established frameworks Symfony and Sylius. The front-end runs as a responsive single page app with Ember.js and uses advanced technologies such as Progressive Web App (PWA) and Server Side Rendering (SSR) to ensure fast loading times and partial offline availability.

A consistent test-driven development approach, both in the back-end and in the front-end, as well as the hosting in the Amazon Cloud (AWS), complete the technical concept.

fence configurator

[ more ] is one of the old hands among the online suppliers of fencing and accessories. The many years of experience in this segment, as well as the huge range of different fencing systems, have made the shop one of the first websites for fencing on the internet. Many years ago, they already recognized the enormous advantages of configurators and developed a very innovative Flash-based configurator for that time.

However, the introduction of HTML5 and the increasing lack of support for Flash made a complete redesign of the configurator inevitable. kaliber5 had the task of replacing the old Flash-based fence planner with a new, modern configurator. This should not only set new technical standards in the industry, but also score points in terms of usability and user experience, and thus achieve maximum conversions.

Even low-tech users can now easily plan and order their individual fence on desktop and tablet devices. The fence planner automatically calculates the required accessories so that the customer does not have to worry about the details (such as the number of screws).

A special highlight is the simple and intuitive Drag 'n' Drop function, which allows the fence to be playfully designed and so makes the configuration an experience.

In an administration backend, the employees of can easily and conveniently manage their fence systems in categories. An import interface picks out the fence elements from the Magento shop completely automatically and updates them daily in the configurator. This means that employees only have to maintain the product data in one central location.

wedding ring configurator

[ more ]

The HCF-Merkle company is a traditional Hamburg wedding ring factory with some of the most modern machinery in Europe.
Even in this industry, a standstill = a backward step. And so in 2008, the kaliber5 company was commissioned to identify ideas and opportunities in order to open up new markets and to optimize existing ones.

Since then, kaliber5 has not only developed a multi-award winning wedding ring configurator for this customer, but also the completely new distribution system called Amodoro. Today, Amodoro is an independent subsidiary of the HCF-Merkle company and makes millions in sales.

The heart of this system is a simple and intuitive to operate configurator. This is used by both end customers and distribution partners, such as jewelers and goldsmiths. This makes it child's play to visualize your own ideas and wishes and to customize your rings so that each one of them is truly unique. There are millions of combinations - of course, only those that are producible. The system also takes over the price calculation, quotation and order processing. Since then, the sales partners are always up to date and can follow the status, production progress and delivery of the ordered goods at any time.

The introduction of this system was a huge success for the HCF-Merkle company. The result: new customers, significant sales growth and a not inconsiderable increase in efficiency.

diamond jewelry configurator

[ more ]

CHRIST Juweliere und Uhrmacher seit 1863 GmbH (CHRIST jewelers and watchmakers since 1863 GmbH) is the largest chain store of the German jewelry industry and is also one of the customers of kaliber5. kaliber5 developed a diamond ring configurator for the company, which is based in Hagen/Westphalia.

CHRIST has a large and varied assortment of diamond rings. The models are offered in various precious metal alloys, stone sizes and stone qualities and can be engraved according to customer requirements. It is impossible to keep all the variations of these products in stock and certainly not in so many stores.

However, in order to be able to offer and show the whole variety to the customer, CHRIST relies on a configurator. This is available to every branch online and is also integrated on Via the configurator, both the branch employees and the end customers have access to all possible model variants and the corresponding prices, and are able to directly order the desired goods via the system. The orders are routed directly to the respective supplier or warehouse, and also, the product configurator indicates whether a ring is in stock in the respective store. The configurator is connected directly to the merchandise management system of CHRIST.

Baumann Springs

technical springs configurator

[ more ]

The Swiss Baumann Federn AG, headquartered in Ermenswil in the canton of Zurich, has been developing, producing and distributing springs and stamped parts at eleven locations worldwide for more than 125 years. With around 1,400 employees, the company has developed an international market-leading position and a well-known customer base in the automotive, electronics and medical technology industries.

For the dynamically growing and innovative business area of contact elements, kaliber5 conceived, designed and developed a B2B configurator application of the highest technical standard. The configurator allows the engineer - whether on the customer or vendor side - to design an individually designed and manufactured contact element, a special technical spring, which is usually used for power transmission. The user can intuitively adapt the product to his needs and adapt it to his specific needs through step-by-step optimization. The product configurator supports him by doing a lot of calculations in the background. This always ensures that all parameters are within reasonable and producible limits. In addition, the effects on the corresponding performance values of the component are calculated and displayed with each change: the maximum power transmission, and the mechanical properties such as the maximum spring deflection. Based on these calculations, even dynamically generated diagrams can be displayed that show the physical relationships between the currently selected product parameters and the resulting performance values.

The project was designed and developed in close cooperation with the customer. Due to the complexity and the desired innovative implementation, only a development according to agile methods was promising. In a short conceptual phase, the product vision was developed using mockups. The detailed conception, implementation and evaluation were then carried out within the agile project management framework Scrum in many iterations, the sprints, in order to be able to provide the customer with maximum transparency and optimal user-centered quality of the end product.

One of the biggest challenges in this project was to package the many parameters of this very technical product into a conclusive UX concept so that customer-side engineers can also use the configurator and understand the actual product behind it. Thus, a control concept was deliberately chosen that resembles the look of CAD software. In addition to entering values in fields, the user can also interactively edit the product dimensions using drag-and-drop. The modern front-end ensures that the boundaries between browser-based websites and interactive desktop software merge. On the other hand, the development team was confronted with a product that, however plain and simple it may seem to the layman, requires understanding of a variety of complex mathematical / physical contexts. As an example: for the determination of the mechanical properties, calculations in three-dimensional space had to be combined with numerical methods of the zero-point search. In order to still keep the performance and speed of the application high, these values were pre-calculated and stored with several million data points in a database - from this, a linear interpolation method in four-dimensional space determines in a fraction of a second the exact approximated value up to several decimal places.

The application has been online since June 2015 and continues to evolve.

disability calculator

[ more ]

The ERGO insurance group has been one of the customers of kaliber5 since 2006. Since then we have implemented various projects for ERGO. One of them is the ERGO disability calculator. This illustrates in a very understandable way, based on a graph of the human body, when a particular degree of disability is reached. Whoever loses one of his two eyes, for example, has already reached a degree of disability of 50%.

ERGO offers its customers several accident insurance policies, which differ primarily in terms of the different levels of capital payments, depending on the degree of disability. For some products with a so-called "progression", the capital benefit increases significantly at higher degrees of disability. This is illustrated very clearly in an interactive diagram, with which the comparison of the different tariffs is simplified. The user can thus easily find out which ERGO product is the most appropriate for him and what he can expect in the extreme case.

As a purely client-side JavaScript application, the web application was designed so that it could be integrated into various communication channels, from through the ERGO app to the desktop software for the ERGO sales partners for customer advice on site.

insurance calculator

[ more ]

Harley-Davidson Insurance Services is a collaboration between Harley-Davidson and ERGO to provide Harley drivers with bespoke and optimal all-round insurance coverage.

On the portal, Harley owners can not only take out motor vehicle liability and fully comprehensive car insurance, but also take out other insurance products, such as accident, risk and legal protection products, or simply obtain information about them and contact local consultants.

kaliber5 programmed the rate calculator for these special insurance products and of course also implemented the entire associated website. All Harley insurance products are calculated using the software developed by kaliber5, which is used not only online, but also by over 150 insurance agencies in Germany and Austria. This web-based software independently generates all contract documents and provides provisional EVB numbers. Damage reports can also be made directly via the insurance portal.

We would like to thank Harley-Davidson and ERGO for the trust they have placed in us and we are very pleased to be able to technically supervise this above-average successful cooperation since its inception.
