Enter information for a company just once instead of once as a prospect, then as a customer, then when a refund is required, and so on. Add only the information required to support the different relationships. For example, where to send an invoice or a purchase order.
Select attributes to define a relationship with a company. Do you sell to them? Buy from them? Is it strictly a banking relationship? Change and add those attributes as necessary.
View a company based on a particular relationship. See them as a customer when selling to them. View them as a vendor when making purchases. Having a company entered only once allows credit memos to be readily coverted to a payable or sales invoices to be directly offset against a payments to a supplier.
Convert prospects smoothly into customers with a single keystroke, and bring their quotes with them. Easily change from buying from a company to also selling to them when the relationship changes.
