Absolutely not. We have customers who have almost 10+ PunchOuts with different procurement systems running on the same store. Since VARStreet comes with a default functionality where the catalog and pricing shown on the store can be easily configured for a login, you can practically have any number of customers using PunchOut with varied procurement systems on the same store. We also support landing page configuration by logins so you can configure the look and feel of the store based on the customer and give your larger customers highly personalized and special treatment.
