What is a .850 file?

The .850 file extension typically represents an EDI (Electronic Data Interchange) 850 Purchase Order document. This is a standardized electronic format used by businesses to send purchase orders to suppliers. Instead of a traditional paper invoice or PDF, this structured data file communicates essential order details like item numbers, quantities, pricing, and shipping information. It's designed for automated processing by computer systems, enabling faster and more accurate transactions between trading partners. The goal is to streamline the procurement process by eliminating manual data entry and reducing errors.

Technical Details

The .850 format is part of the X12 EDI standard and is a plain text, structured data file. It uses segments and elements to define specific pieces of information, such as the buyer, seller, items ordered, and quantities. The hierarchical structure allows for complex order details to be communicated clearly and unambiguously between different software systems.

Did You Know?

EDI (Electronic Data Interchange) has been around since the 1960s, with X12 standards developing significantly in the 1980s.
The .850 format is just one of hundreds of transaction sets defined within the X12 standard, covering everything from invoices to shipping notices.

Security Information

.850 files are typically plain text and do not inherently contain executable code or malicious content. However, ensure files come from a trusted trading partner, as inaccurate or fraudulent data could still be transmitted.
