How it works

Three steps to live Costco EDI.

Stacksync handles the complexity of Costco EDI so your team doesn't have to. Connect your ERP, WMS, or database through a simple API, we translate, validate, and deliver every transaction automatically.

  1. 01

    Connect your systems

    Plug Stacksync into your ERP, WMS, or database with a no-code connector. We handle authentication, schema discovery, and field mapping.

  2. 02

    Map to Costco guidelines

    We ship pre-built mappings for every Costco document type. Override any field, add custom validation, or extend with custom code.

  3. 03

    Send & receive in real time

    Stacksync translates, validates, and delivers every transaction over AS2, SFTP, or API. Watch every document flow live in the dashboard.

Why Stacksync

Built for EDI suppliers, not enterprise legacy.

From pre-built Costco mappings to real-time compliance checks, Stacksync removes the friction from EDI, so you can focus on growing your business.

  • Pre-built mappings

    Stacksync ships native mappings for every Costco document type. No more 6-week field-mapping projects.

  • Real-time monitoring

    Every transaction shows up in the dashboard the second it lands, with retry, revert, and replay built in.

  • No vendor lock-in

    Your data lives in your ERP/WMS/database. Stacksync is the translation layer, not the system of record.

  • Days, not months

    Most Costco suppliers go live in under a week. We migrate from SPS Commerce, TrueCommerce, Cleo and IBM Sterling.

Costco uses X12. Stacksync supports both X12 (the dominant North American standard) and EDIFACT (the dominant European and global shipping standard) for every connected trading partner. Channel-specific implementation guidelines from Costco are pre-built into the Stacksync connector and validated on every outbound transaction.

Costco supports 12 transaction codes in total. The most common include: 860, 850, 820, 824, 810, 856, 990, 214. Each code is mapped to its business-record equivalent (purchase order, ASN, invoice, etc.) inside Stacksync, so EDI exchanges land directly in your ERP or warehouse without manual translation.

Most Costco EDI integrations go live in 3 to 10 business days.
