Cost centers are of no interest to casual customers, but regular business customers, specially corporate ones love them. Their accountants do, perhaps.
We always had an option of giving a list of cost centers per catalog, but it may be hard to maintain, so we added a new feature – free text cost centers.
Simply enter * as the only text in the cost center text box in catalog details and the user will get an additional field for entering a free text cost center in the order form.
