Common questions from suppliers beginning their 99 Cents Only EDI compliance journey.
99 Cents Only requires four core EDI transactions: the EDI 850 Purchase Order (inbound from buyer), the EDI 855 PO Acknowledgment (outbound, required within 1 business day of PO receipt), the EDI 856 Advance Ship Notice (outbound, transmitted as shipment leaves your facility), and the EDI 810 Invoice (outbound, one per PO). Optional transactions include the 820 Payment Remittance, 860 PO Change Request, and 753/754 Routing Instructions.
99 Cents Only requires the EDI 856 ASN to be on file before or at the time the physical shipment arrives at their receiving facility. Shipments received without a valid ASN, or with an ASN that arrived after the goods, are subject to compliance chargebacks. In some cases, the receiving team may delay or refuse the shipment until the ASN is on file. SBSA transmits the ASN automatically the moment your carrier picks up the order, eliminating this risk entirely.
Yes. All cartons shipped to 99 Cents Only must carry GS1-128 (formerly UCC-128) compliant labels with a valid SSCC (Serial Shipping Container Code). The SSCC on each carton label must match exactly the carton-level SSCC data in the EDI 856 ASN. SBSA Technology generates and validates these labels as part of your automated EDI and WMS workflow, ensuring perfect label-to-ASN alignment on every shipment.
99 Cents Only's primary distribution center is located in Commerce, California, in the Los Angeles metro area. This DC services the entire Southwest store network across California, Nevada, Arizona, and Texas. The exact ship-to address, including dock door and routing instructions, will be specified in the EDI 850 Purchase Order or communicated during your trading partner onboarding.
99 Cents Only expects purchase orders to be shipped complete. If you cannot fulfill certain lines, you must reflect this in your EDI 855 PO Acknowledgment by updating quantities or providing a revised ship date at the line item level. Do not include unfulfillable items in your ASN — remove the lines from the 856 entirely rather than including them with a quantity of zero, as zero-quantity lines are classified as non-compliant data.
SBSA Technology typically completes 99 Cents Only EDI onboarding in 2–4 weeks, depending on your ERP system, fulfillment setup, and existing EDI infrastructure. The process includes connection setup (AS2, SFTP, or VAN), document mapping for all required transactions, ERP and WMS integration, GS1-128 label configuration, and testing in the 99 Cents Only test environment before go-live.
