{% hint style="warning" %}
It is important that a Customer imported from Nexudus is selected during the sale in the ePOS app, otherwise the system can not match the Customer that made the payment.&#x20;

It is advisable that only Products imported from Nexudus are selected during a sale.  If a sale is made using a mixture of Nexudus and non-Nexudus Products, only the Nexudus products will be visible on the Invoice, the cost of which will be calculated based on only the Nexudus Products.
