For MExT, a company that provides first medic products in a B2B market, I build a multidomain Drupal 8 website with a Drupal 8 Commerce 2.0 webshop integrated. The webshop is fully integrated with MS Dynamics Navision, via a Soap integration. The webshop integrates with Navision for synchronizing customers (in specific groups), products (with diffrent prizes depending on the usergroups), customer adresses (so users can directly select previously used addresses), appointments, order history and orders. When a customer places an order, it gets directly pushed to Navision. We also added a fallback system that is used when this system fails, so we always get a notice via mail with the specific error message. The website was made in 3 languages (Dutch, French, German) and is used on 4 domains (NL, BE, LU, DE).
