EDI vs PDF Orders: What's the Difference?
Two ways businesses exchange purchase orders, and why most small and mid-sized companies still rely on PDFs.
What Are EDI and PDF Orders?
EDI, or Electronic Data Interchange, is a standardized format for exchanging business documents electronically between computer systems. When a customer sends you an EDI purchase order, the data arrives in a structured, machine-readable format that your system can process directly without any human interpretation. EDI has been around since the 1970s and is the backbone of order exchange for large enterprises, major retailers, and healthcare organizations. Common EDI document types include the 850 (purchase order), 810 (invoice), and 856 (advance ship notice).
PDF orders, on the other hand, are human-readable documents sent as email attachments or downloaded from portals. A PDF purchase order contains all the same information as an EDI order, such as customer details, shipping address, line items, quantities, and pricing, but it is formatted for a person to read, not a machine. To get the data out of a PDF and into your accounting or order management system, someone has to either type it in manually or use parsing technology to extract the fields automatically.
Both formats serve the same purpose: transmitting order information from buyer to seller. The critical difference is in how that data gets into your system and how much effort it takes to process.
Why It Matters
EDI is fast and structured. Because the data is already in a format computers understand, there is no parsing or extraction step. An EDI order can flow directly from your customer's procurement system into your ERP or accounting platform in seconds. However, EDI comes with significant barriers. Setting up EDI connections typically costs between $5,000 and $50,000 depending on the complexity, and both the buyer and seller must support the same EDI standards. For small and mid-sized businesses, this cost and complexity is often prohibitive, especially when you are only exchanging a few hundred orders per month.
PDF orders are universal. Every business can create and send a PDF. There is no setup cost, no technical requirements on the sender's side, and no need for both parties to agree on a data format. The tradeoff is that PDFs require processing to extract the data. If that processing is done manually, it means someone on your team is typing every order into your system by hand. If it is done with automation, parsing tools or AI models extract the data and push it into your system automatically, giving you speed comparable to EDI without the setup cost.
The practical reality is that most small and mid-sized businesses receive the majority of their orders as PDFs, not EDI. Even companies that have EDI connections with their largest customers still receive PDF orders from smaller accounts, new customers, and one-off purchases. The question is not whether you will deal with PDF orders, but whether you will process them manually or automatically.
How OrderSync Pro Handles Both Formats
OrderSync Pro specializes in PDF order processing using AI-powered parsing that can handle any PDF format without requiring your customers to change how they send orders. Whether a purchase order comes from a hospital procurement system, a wholesale buyer's email, or a retail chain's vendor portal, our workflows extract every field accurately and push the data into your accounting and shipping systems instantly. You get the speed and accuracy benefits of EDI without the cost or complexity of setting up EDI connections.
Our approach to purchase order processing is format-agnostic. We build a single automation workflow that intelligently handles dozens of different PDF layouts from different customers. The system identifies which customer sent the order, applies the correct parsing logic, extracts all line items and header data, and creates the corresponding records in your system. For clients who also receive EDI orders from larger trading partners, we integrate EDI translators into the same workflow so that all orders, regardless of format, flow through one unified process.
The result is that your team never has to think about whether an order came in as EDI or PDF. Every order is processed automatically, accurately, and instantly. To learn more about the parsing technology behind this, see our glossary entry on OCR vs AI data extraction.
