Retail integration
What Dollar Tree publishes for merchandise vendors about electronic purchase orders and invoices, EDI testing with its onboarding partner, the Ariba vendor portal, shipping portals and international payment terms.
Overview
Who this is for: Merchandise vendors selling to Dollar Tree stores and distribution centers in the US and Canada, including import vendors, and the EDI and accounting teams that support them.
Dollar Tree's vendor pages set one clear rule for merchandise vendors: they must receive purchase orders and send invoices electronically. Vendors can do that in two ways, through the Dollar Tree vendor portal on the Ariba Network or through EDI. Vendors choosing EDI complete a testing process with Dollar Tree's onboarding partner to validate the document formats, but Dollar Tree states that vendors do not have to use Dollar Tree's onboarding partner as their EDI tool or network.
Shipping runs through separate portals. Every vendor shipping into Dollar Tree distribution centers in the US and Canada, prepaid or collect, creates an order release in the Custom Vendor Portal and then books a live unload appointment in C3 Reservations. Import vendors send invoices and forwarder's cargo receipts by EDI where they can, with standard terms of 120 days from receipt of both documents.
The public pages do not list X12 transaction numbers or versions for merchandise vendors. The EDI specification on Dollar Tree's site is an Ariba guide for non-merchandise vendors and carries a confidentiality notice, so we did not use it. This guide records what Dollar Tree publishes and lists what we could not confirm.
Requirements at a glance
Dollar Tree requires merchandise vendors to receive purchase orders and send invoices electronically, through EDI or its Ariba Network vendor portal. Its public pages do not list X12 numbers or versions for merchandise vendors; formats are validated in testing with Dollar Tree's onboarding partner. We checked the pages on October 31, 2026.
Receive purchase orders, key in invoices and check invoice and payment status, for vendors not using EDI.
Order releases for prepaid and collect shipments into Dollar Tree distribution centers.
Live unload delivery appointments at each distribution center, using the CVP shipment number.
Business units and channels
Large retailers often handle each business unit or channel as a separate EDI relationship, with its own documents, guides and setup. Confirm with Dollar Tree which of these you supply before mapping.
Stores and distribution centers
HHP/HBC, Variety, Seasonal and Basics divisions, plus Closeouts and Opportunity Buys, supplying stores in 48 states and 5 Canadian provinces.
Stores and distribution centers
Distribution centers that every vendor ships into through a CVP order release and a C3 appointment.
International
Import vendors, who send invoices and forwarder's cargo receipts by EDI where possible, on net 120 terms.
Other channel
Suppliers of items not for resale, such as supplies and equipment, who integrate with Dollar Tree on the Ariba Network by cXML or EDI.
Workflows
General guidance: typical flows in this industry, not Dollar Tree's published process.
Documents and APIs
General guidance. We could not verify Dollar Tree's EDI requirements from a published source, so these are documents commonly exchanged in this industry, not Dollar Tree's confirmed requirements. Confirm the list, versions and programs with Dollar Tree.

Read from top to bottom. Solid arrows are documents Dollar Tree names in its own public documentation; dashed arrows are common practice that this page could not confirm for Dollar Tree, or acknowledgments. The order is typical, not a Dollar Tree rule: programs such as vendor direct to consumer use their own documents and timing.
Document by document
For each document: what it does for you as the supplier, what Dollar Tree's own documents say about it (with the source and its date), and general EDI practice that helps, labelled as such. Your Dollar Tree mapping guide for your version is the final word on fields and codes.

Avoid these
Dollar Tree's onboarding partner runs its EDI testing, but you can keep your own EDI provider or network.

Challenges
Merchandise vendors must trade orders and invoices electronically, so a low-volume vendor needs either EDI or the Ariba portal from the start.
Order releases and appointments live in separate portals, so shipment data must be keyed or integrated there as well as in EDI.
Import vendors are paid 120 days from receipt of both the EDI invoice and the forwarder's cargo receipt, not from the invoice date.
