How frequently should EDI 846 Inventory updates be sent to Macy's?

Macy's's required frequency for EDI 846 updates depends on the fulfillment model. Dropship programs often require daily or even intraday inventory feeds — some Macy's divisions expect updates every 4 to 6 hours to minimize overselling. Warehouse-replenishment programs may accept weekly 846 updates. Stacksync monitors your inventory system for stock level changes and can send 846 updates on a scheduled interval or when quantities change beyond a configurable threshold, ensuring Macy's always has accurate availability data without overwhelming their systems with unnecessary transmissions.

Is EDI 846 required for Macy's dropship programs?

Most Macy's dropship programs require EDI 846 Inventory Advice to prevent overselling — if you sell products through Macy's's marketplace or website, they need real-time visibility into what you can actually ship. Without accurate 846 data, Macy's may list items as available that are actually out of stock, leading to order cancellations and poor customer experience. Stacksync integrates directly with your warehouse management system to push 846 updates automatically whenever stock levels change, ensuring Macy's's product listings always reflect your actual fulfillment capacity.

What happens when inventory reaches zero in an EDI 846?

When an item reaches zero available quantity in your EDI 846, Macy's's systems typically remove it from available-to-sell inventory. For dropship, this means the product page may show 'out of stock.' For replenishment, it signals that Macy's should hold off on ordering until stock is replenished. It is important to send a zero-quantity 846 rather than simply omitting the item — omission may be interpreted differently by Macy's's system. Stacksync handles zero-quantity items explicitly and can optionally suppress items below a safety stock threshold to prevent overselling.

How does Stacksync automate Macy's EDI 846 inventory feeds?

Stacksync connects to your inventory management system, WMS, or ERP and pulls real-time stock data including quantity on hand, available-to-promise, and backorder quantities. The platform formats this data into the 846 document structure with proper UPC/SKU identifiers, location codes, and quantity qualifiers. You configure the transmission schedule — hourly, daily, or event-triggered — and Stacksync handles the rest. The platform also tracks Macy's's inventory receipts so you can identify discrepancies between your reported inventory and what Macy's has actually received.
