Zappos and 6pm EDI 850 FAQ
Common questions about 850 Purchase Order transactions with Zappos and 6pm.
What information does Zappos and 6pm include in an EDI 850 Purchase Order?
Zappos and 6pm EDI 850 Purchase Orders contain item-level detail including UPCs or GTINs, ordered quantities, unit pricing, ship-to addresses, and requested delivery dates. Key segments like BEG (beginning of the PO), PO1 (line items), N1 (party identification), and CTT (transaction totals) structure the document. Zappos and 6pm sends 850s electronically through their EDI network, and each PO must be acknowledged with an 855 to confirm receipt. Stacksync parses these fields and maps them directly to your ERP or database so orders appear automatically without manual data entry or CSV imports.
How quickly does Stacksync process Zappos and 6pm EDI 850 Purchase Orders?
Stacksync processes incoming Zappos and 6pm 850 Purchase Orders in real time, typically within seconds of receipt. The platform validates the X12 envelope, parses all segments, maps fields to your system's schema, and inserts the order record automatically. Unlike batch-processing EDI providers that run on scheduled intervals, Stacksync's event-driven architecture means your team sees new Zappos and 6pm POs immediately. This speed is critical for meeting Zappos and 6pm's tight fulfillment windows and maintaining high on-time in-full compliance scores.
What are common reasons a Zappos and 6pm EDI 850 Purchase Order gets rejected?
The most frequent rejection causes for Zappos and 6pm 850s include invalid UPC or GTIN codes, incorrect ship-to location identifiers, quantities that don't match Zappos and 6pm's rounding requirements, and missing mandatory segments. Formatting issues like incorrect date formats in the DTM segment or invalid N1 qualifier codes also trigger rejections. Stacksync validates every incoming Zappos and 6pm 850 against known compliance requirements before syncing to your system, flagging anomalies immediately rather than silently dropping the transaction.
Do I need to send an EDI 855 after receiving a Zappos and 6pm 850 Purchase Order?
Zappos and 6pm typically requires an EDI 855 Purchase Order Acknowledgment for every 850 received. The 855 confirms that you received the PO and indicates whether you can fulfill it as ordered, need to modify quantities, or must reject specific line items. Most Zappos and 6pm compliance programs expect the 855 within 24 to 48 hours of PO receipt. Stacksync can generate and send 855 acknowledgments automatically based on your acceptance rules, ensuring you never miss a compliance deadline. A 997 Functional Acknowledgment may also be required as a separate technical receipt.
How does Stacksync map Zappos and 6pm EDI 850 fields to my ERP system?
Stacksync uses a visual field mapping interface to connect Zappos and 6pm 850 segments — such as BEG for PO header data, PO1 for line items, and N1 for party identification — to the corresponding fields in your ERP, WMS, or database. You configure the mapping once, and Stacksync applies it to every subsequent Zappos and 6pm 850 automatically. The platform handles data type conversions, conditional logic for optional fields, and Zappos and 6pm-specific formatting requirements. If Zappos and 6pm changes their 850 specification, Stacksync alerts you and suggests mapping updates.
