For decades, EDI (Electronic Data Interchange) has been the default way large companies place online orders. It was designed for high-volume, pre-approved transactions moving directly from one ERP to another, without human involvement. For the right relationships, EDI works.
The problem is that many B2B relationships don’t operate at the scale needed for EDI to remain profitable.
Traditional EDI integrations are expensive, time-consuming to implement, and typically custom-built for each partner. It’s common for an EDI setup to take months and cost tens of thousands of dollars on both sides. As a result, most midsize companies only use EDI with one or two of their largest customers (i.e. the ones whose order volume justifies the investment).
That leaves a gap. Many buyers want EDI-like automation because they place too many orders to make every one via clicks on an ecommerce site and yet don’t buy enough with any one company to justify a full EDI project.
That gap is exactly what Nomad eCommerce’s Direct Order Placement feature—powered by our external order API—is designed to address.
An EDI Alternative Built for the Midmarket
At a high level, Nomad’s Direct Order Connection is an EDI alternative. Instead of forcing everyone into rigid, expensive EDI integrations, Nomad provides a direct, open endpoint that allows orders to be placed from one system directly into another.
That way, when discussions around EDI come up, this gives those manufacturers, distributors, and wholesalers who run their ecommerce sites on the Nomad Platform another option—something faster to implement, easier to manage, and far more flexible. In simple terms, it delivers EDI-like integration without requiring an actual EDI project.
However, our Direct Order Connection is not designed to replace EDI everywhere. EDI still makes sense for very large, very strategic trading partners. But for the many customer relationships where EDI is impractical, Direct Order Placement offers a modern alternative.
How Direct Order Placement Works
From the buyer’s perspective, the process is straightforward and familiar. They log into their ERP, prepare a purchase order, get it approved, and press a button to submit it
With traditional EDI, that button sends a large XML file through a custom-built connection to a specific endpoint. With Nomad’s Direct Order Connection, that button sends the order directly into the Nomad eCommerce platform.
Once the order reaches Nomad, it is handled exactly like an order placed on the Nomad-powered ecommerce site. It is received, processed, and then moves into your ERP the same way any other sales order flows. Nomad sends order confirmation emails, generates order documents, and provides order status updates.
There is no need to create a CSV. There is no file to upload. There is no reason to log into the website.
It is a system-to-system process that starts and ends in the ERP.
Filling the Gaps EDI Leaves Behind
For many vendors, EDI only makes sense for one or two large customers whose order volume can justify the cost of an EDI connection. Extending Electronic Data Interchange to smaller customers quickly erodes margin, which is why most vendors stop there.
Direct Order Placement fills that gap by giving vendors an EDI-like integration option for customers who want system-to-system ordering but are not large enough to justify a full EDI build.
And that’s the real value: EDI-like automation without EDI-level cost or complexity.
Clear Roles, No Custom Builds
Everything works because each party is responsible for the part of the process they already control.
Nomad is responsible for receiving the order, processing it, and moving it through to your ERP. When an order is submitted, Nomad validates the data before creating the order. If something is missing or incorrect, the system returns clear feedback so the sender knows what needs to be fixed. Once the order is accepted, it behaves like any other order—there is no parallel system, no special exception, and no new downstream complexity.
Your role as the vendor or supplier does not change. You enable the feature, decide which customers should use it, and share the documentation. You are not asked to build or maintain custom integrations for every buyer, which is where traditional EDI projects often stall.
Your customer is the one who adds the connection on their side (think of the “submit” button in the ERP). That’s where the purchase order lives, where approvals happen, and where system-based ordering already makes sense. By hitting “submit”, they simply send that approved order into Nomad.
Direct Order Connector is a Smart Alternative
Direct Order Placement isn’t trying to replace EDI everywhere as a one-size-fits-all solution. It’s a targeted solution for a very real problem in B2B commerce—one that sits squarely between ecommerce sites and full EDI integrations.
For companies looking for EDI alternatives that preserve automation without inheriting EDI’s cost and complexity, Nomad’s Direct Order Connector offers a modern, practical path forward.
