Almost drowning in sales, we had to keep our newly found customers happy while they (and we) waited on the orders to arrive. Even tough we communicated 30 days delivery, people started mailing after 10 days already, asking when their order would come.
It was our first confrontation with customer service – one of the challenges that taught us a lot over the course of the company. On average, every customers e-mailed us 1.6x for every order. We did not anticipate that, to say the least.
