What is a kilo-character? In the EDI industry, service providers will typically bill transactions by the volume of kilo-characters. A kilo-character corresponds to one thousand characters in a file. A character corresponds to a every single character, every single space, and every single delimiter contained within an EDI file. When an entity like OpenText bills a customer, they typically bill by the number of kilo-characters for a given month. To determine the number of kilo-characters, you divide your total number of characters by a thousand. Most operation systems (windows, mac) will allow this information to be readily available by simply viewing the file properties.
There is a trend in the industry that involves billing to occur by transaction (or message) rather than kilo-character. This takes the complexity out of the equation by ignoring the volume of data contained within a message. A message equals one specific business transaction. An invoice or shipment advice would be an example of one transaction count. There can be one or more transactions within a file.
