Payment Reminders

A competitor is anyone who offers the same product/service that you do.

However, upon payment, your competitor is any other company to whom your client also owes money.

For example, your company sells insurance to Pedro Garcia, but your competitor, on collection, is any other company to which Pedro Garcia owes money, as cable television, electronic security systems, subscription services, etc... The list is enormous. Here we fulfill "collecting first holds double value".

How much does a client appreciate to be reminded of a due date, instead of contacting him, when overdue?
