Costco runs two vendor programs that share almost nothing, including the network they trade on. Costco Wholesale ships bulk freight to depots over ANSI X12 EDI, with the 850, 856, and 810 reconciled in a strict three-way match and an advance ship notice that has to beat the truck to the dock. Costco.com is a different world entirely: drop-ship orders to individual members, traded through Rithum's OrderStream network rather than raw EDI. This guide walks through both programs side by side, the documents each one requires, where Costco's own item numbering and GS1-128 label rules trip up new vendors, and what it takes to get certified and connected without building the EDI mapping in-house.

What people consistently say they love about QuickBooks Online is that it's simple enough to manage without an accounting background. Adding a multichannel operation on top of it puts that simplicity at risk, hundreds of individual order transactions can turn clean books into a mess fast if the setup is wrong from day one. This walks through the actual InfiPlex-to-QBO setup, step by step, including the decisions that determine whether your books stay organized once real order volume hits.

QuickBooks Online is increasingly not a choice, it's where Intuit is pushing every QuickBooks user, and its API reflects that it was built as an accounting system first. This covers what's actually happening with QuickBooks Desktop's shrinking support window, the real constraints QBO's API puts on any integration built against it, and how InfiPlex connects to it.

Prophet 21 doesn't have one clean API that hands over everything a connected system needs, and that shapes almost every integration built for it. This guide covers why P21 integration is a different problem than a modern cloud ERP, what the existing P21 integrator landscape mostly looks like, and how InfiPlex connects to it instead.

Most NetSuite integrations sync once a day because of how they're built, not because NetSuite makes them slow. This guide covers NetSuite's real concurrency and rate limits, why batching became the default workaround, and how a connection built around real-time, event-driven sync looks instead.

Walmart runs two very different supplier relationships under the word "integration," and mixing them up is the fastest way to build the wrong connection. This guide covers Walmart Marketplace and Walmart DSV side by side: how to tell which one you're in, the EDI documents DSV requires, and where Walmart Fulfillment Services actually fits.

Target runs two separate EDI vendor programs, and mixing up their rules is where most new vendors get hurt. This guide covers the 850, 855, 856, and 810 for both Target Stores and Target DVS: what goes in each document, where the two programs diverge on labeling and invoicing, and why the 856 causes the most chargebacks.

Home Depot assigns several different numbers to the same product, and the one you need depends entirely on what you are trying to do with it. This guide covers each identifier Home Depot uses for suppliers, where to look each one up, which number belongs on a purchase order, ASN, or invoice, and how to map them all to your own SKUs.

Mercado Libre Global Selling reaches Mexico, Brazil, Chile, and Colombia through one cross-border account, built on a parent item, a child item per marketplace, and a two-level user hierarchy. This guide covers why item IDs differ per site, the three ways to pause a listing, what to do when there is no bulk endpoint, searching by status, and deleting items in the order Mercado Libre requires.

InfiPlex Bridge EDI to API turns EDI trading-partner requirements into normal orders, delivered through the exact same REST API, JSON shape, and Bearer token authentication used for every other connected channel. This guide covers direct connections versus a VAN, the real endpoints behind it, how inventory sync and partial shipments work for EDI retailers, and the full list of trading partners connected today.
