Well sold

eCommerce platforms and online stores

Our future is digital. Those who do not yet sell their products and services online can suffer extreme competitive disadvantages. We design, advise, optimize, repair and implement your online store with technical, psychological, UX and marketing expertise. SEO, GDPR, accessibility and the best possible performance are essential core elements.


Conception and implementation of eCommerce platforms and online stores

If you want to sell your products or services online, there are a variety of possible store solutions. To identify the right store system, we support you in the design and implementation of your online store or analyze your existing online sales platform for possible improvements to increase sales.

eCommerce advice on technology and increasing conversion

Which is the right store system? How can I increase my conversion rate (CRO) and boost sales in my online store? How can my online store be found faster on Google? How can I implement necessary GDPR measures and accessibility? We will be happy to answer any questions you may have during an eCommerce consultation.

Sales promotion measures and designs

Are your products not selling despite high visitor numbers in your online store? Or are you planning to sell your products and services in a new online store? With our user-centered designs and measures for new and existing online stores, you can increase your sales figures.

Maintenance of online stores

An online store can only sell if it is technically flawless and performs well. To ensure the availability of your online store, we take care of maintenance by installing the necessary updates. And to avoid a rude awakening in an emergency, we automatically create daily backups that are stored on secure GDPR-compliant servers in Germany.

Store Management

We support you in maintaining your products, prices and store settings and are happy to take this time-consuming work off your hands. Automated imports and exports of product data across stores and platforms allow you to concentrate on selling instead of moving Excel lists back and forth. If you would like to offer your products in multiple languages, we can translate your online store individually or automatically.

We have been working with Mastflow for about a year now and are very satisfied with their work. Mastflow’s uncomplicated communication and quick solutions have convinced us to continue working with the agency in the long term. It’s a relief to have a reliable agency in the background and to know that the support you need will always be there when you need it. We are glad that we found this agency.

In our search for a company that takes care of our concerns, wishes, changes and optimizations, we came across Mastflow on the Internet. After a brief preliminary discussion, we immediately realized that Mastflow was the ideal solution for us due to its broad positioning. Tasks are completed in the shortest possible time, communication is smooth, fast and goal-oriented. Mastflow often offers several options that lead to the desired goal, so that we choose the right one for our company and it is implemented promptly. The price-performance ratio is optimal – we would make the selection again at any time and hope for continued successful cooperation!
Despite a number of much cheaper providers, we opted for MASTFLOW. I am happy about it and have no regrets – on the contrary! The online store implementation based on WordPress was anything but easy: the plugin providers did not keep their promises and made the project a real challenge. In the end, we had to switch to a completely different system so that our requirements could be met at all. Project implementation was therefore anything but easy. But with Steffi’s always friendly and courteous manner, as well as her competence and quick response to our concerns, it was fun to implement the project with Mastflow despite the technical adversities! I don’t even want to think about where we would be now if we had opted for one of the cheaper providers. Now our store is running as desired and we are very happy!
