Sander van Tilburg Google review · 5/5

A nice connection to StoreLinkr for our WP website of Dutch Light Trading BV to manage and publish articles.

Mathieu van Loon Google review · 5/5

We are very satisfied with the data link between CycleSoftware and our website. It saves us a lot of time because we work with inventory management. Thanks to the connection, the stock in the webshop is always up to date.

Christian Schattevoet

The data link works great and fast, stock is immediately adjusted whether something is sold in the store or webshop. The time you save depends on how much you sell, but you do no more manual stock correction. The connection saves on double sales or ordering more quantities than in stock.

Aster de Nil, Fietsen Aster

We are satisfied with the link. It saves us at least 2 hours a week. When a bike is sold it is quickly taken off the internet, so no more people come for a bike that is already sold.
