Best EDI Software for Manufacturing ERP and Customer Orders (2026)

The best EDI software for a manufacturer depends on who runs it. Full-service EDI providers such as SPS Commerce, TrueCommerce and Epicor's own EDI services build the maps, connect the trading partners and keep them compliant for you. EDI platforms such as Cleo, OpenText Trading Grid, IBM Sterling and Orderful give your team or an integrator the tools to do that work. Neither reads the purchase orders that arrive as PDFs and emails, so most manufacturers pair EDI for the partners that require it with an order-entry agent such as Fluent or a tool such as Conexiom for everyone else.

Fluent is one of the options below, and it is not an EDI provider. We have tried to be fair.

Why manufacturers need two answers for customer orders

Large retailers, distributors and OEMs usually require EDI. They send an 850 purchase order and expect a functional acknowledgment back, then an 856 advance ship notice and an 810 invoice in the format their own guidelines specify. Missing or late documents can mean chargebacks. That is a compliance job, and EDI software exists to do it.

The rest of the customer list orders the way it always has: a PDF attached to an email, a spreadsheet, an order typed into the email body, sometimes a photo. These customers will not set up EDI for you, and an EDI provider has nothing to map. For many mid-market manufacturers this long tail is the larger share of order lines and most of the keying time in Order Entry.

So the buying question has two halves. Which EDI option fits the trading partners who require it, and what handles the orders that never arrive as EDI?

The four approaches

• Full-service (managed) EDI. The provider runs the network, builds and maintains the maps for each trading partner, onboards new partners and integrates with your ERP. SPS Commerce, TrueCommerce (which acquired DiCentral in 2021) and the managed services of IBM Sterling and OpenText fit here.
• EDI and B2B integration platforms. Software your IT team or an integration partner uses to translate, route and monitor EDI and API traffic. Cleo Integration Cloud, OpenText Trading Grid, IBM Sterling B2B Integration and Orderful's API-first platform fit here. Several also sell managed tiers.
• ERP vendor EDI. Epicor sells EDI for Kinetic and Prophet 21, including ManagedXchange, a fully managed service, and Epicor EDI (formerly 1EDI Source). Epicor partners also deliver EDI projects on top of these and third-party tools.
• Order-entry tools for non-EDI orders. Software that reads PDFs, spreadsheets and emails and turns them into sales orders. Conexiom positions itself for the emailed and file-based orders EDI was never built to handle. Fluent drafts the sales order in the ERP for a person to review.

Evaluation criteria

1. Which trading partners require EDI, and which documents?

List every customer that mandates EDI and the transaction sets each one wants: usually 850 purchase orders in, 855 acknowledgments, 856 ship notices and 810 invoices out, sometimes 860 changes and 846 inventory. Each partner publishes its own implementation guide. Ask each vendor whether that partner is already on its network or pre-mapped, and how long a new partner takes.

2. Who builds and maintains the maps?

Partners change their guidelines and add requirements. With full-service EDI the provider updates the maps. With a platform, your team or a partner does. Neither is wrong, but a small IT team should be honest about whether it wants to own map maintenance.

3. How does it connect to your ERP?

Ask how inbound orders become sales orders in Epicor Kinetic, and how shipments and invoices flow back out as 856 and 810 documents. Ask what is installed in or near Epicor, who supports that integration through upgrades, and whether it covers the ship-to addresses, customer part numbers and units your partners use.

4. What happens to orders that do not arrive as EDI?

Pull a month of incoming orders and count how many arrived by EDI and how many by email, PDF or spreadsheet. If most of your customers send PDFs, EDI alone will leave most of the keying in place, and you need a second tool. Check whether that tool can also take EDI or XML if you want one review queue.

5. Where do exceptions land, and who fixes them?

An EDI order can be perfectly formatted and still wrong: an unknown part number, a price that does not match the agreement, a ship-to that is not on file. Ask where these show up, whether the person who fixes them works in the ERP or in a separate portal, and how quickly a corrected order goes back out.

6. How is it priced as partners and volume grow?

EDI is commonly priced per trading partner, per document or by transaction volume, sometimes with a setup fee for each new partner. Order-entry tools use their own models. Model your next two years of partners and order volume against each option's pricing model.

Best for, option by option

SPS Commerce is a full-service EDI provider with a large retail network and pre-built integrations to more than 100 ERP and warehouse systems, Epicor among them. It suits manufacturers whose EDI partners are mainly retailers and distributors and who want the provider to own partner maps and compliance.

TrueCommerce offers EDI software and a fully managed EDI service, with an integration built for Epicor. It acquired DiCentral in 2021, adding DiCentral's network and managed services. It fits manufacturers who want to hand EDI operations to an outside team entirely.

Epicor EDI and ManagedXchange keep EDI with your ERP vendor. ManagedXchange is a fully managed service that handles trading partner specifications and communication over VAN, secure FTP and AS2, and Epicor states more than 50,000 pre-mapped trading partners. It integrates with Kinetic and Prophet 21. It fits Epicor shops that want one vendor for ERP and EDI.

Cleo Integration Cloud combines EDI, API and managed file transfer on one platform and lists an Epicor connector. It suits manufacturers with an IT team, or an integration partner, that wants to own maps and integrations and connect more than the order flow, such as logistics providers and suppliers.

OpenText Trading Grid is a large B2B integration network supporting EDI, API and file transfer, with prebuilt ERP integrations and a choice of self-service tools or managed services. It fits larger manufacturers with global trading partner networks.

IBM Sterling B2B Integration SaaS is a cloud EDI and API service, with a Premium edition that IBM describes as fully managed for teams short on EDI skills. It fits enterprises with high volumes and partners who already trade through Sterling.

Orderful is an API-first EDI platform. You integrate once to its API, and its validation checks each document against the trading partner's own requirements before it is sent. Orderful publishes a guide to connecting with Epicor Kinetic through Kinetic's API. It fits teams with developers or an iPaaS who want to work with EDI as JSON over an API.

Conexiom automates the emailed and file-based orders that EDI does not reach, capturing orders in any format, validating them against the ERP and delivering a clean order. It supports several ERPs, Epicor among them. It suits order desks across multiple ERPs that want one tool for unstructured orders. See Conexiom alternatives for Epicor and Fluent vs Conexiom for a closer comparison.

Fluent is an order-entry agent built around Epicor Kinetic. It reads customer purchase orders in any format, including PDFs, scans, spreadsheets, email bodies, XML and EDI files it receives, and drafts the sales order in Order Entry for a person to review. It suits Kinetic teams whose long tail of PDF and email orders is where the keying time goes.

Where Fluent fits, and where it does not

Fluent is not an EDI provider. It has no VAN connectivity, does not onboard trading partners, does not send functional acknowledgments, and does not produce outbound 856 ship notices or 810 invoices to a partner's guidelines. If a retailer or OEM requires EDI, you need one of the EDI options above for that partner.

Fluent handles the orders EDI does not. The Order Entry agent resolves the customer, the ship-to address, the customer's own part numbers, units of measure as the order states them, and prices against live Epicor data, and flags a purchase order number that is already on an open order. Anything it cannot resolve is drafted with a note of what was searched and waits for a person. Nothing posts until someone processes the draft, and every field read and every decision is recorded on the document.

There are no templates per customer, no field mapping and no model training. Behavior is set with written instructions, and corrections become instructions. Fluent connects to Epicor Kinetic's REST API from outside, with nothing installed inside Epicor, and each agent generates an Epicor access scope listing the services it calls. The same agents are offered for Prophet 21, NetSuite, SAP Business One, Dynamics 365 and other ERPs; Epicor Kinetic is where Fluent is deepest.

The common pairing is EDI for the trading partners that require it, and an agent for the long tail of PDF and email orders. When an EDI or XML file does reach Fluent, for example a partner who emails an EDI file instead of sending it through a network, the agent reads it like any other order. That is a convenience for one review queue, and no replacement for an EDI provider's compliance work.

How to choose

• A few large partners require EDI and you have a small IT team: choose a full-service provider (SPS Commerce, TrueCommerce or Epicor ManagedXchange) and let it own maps and compliance.
• You want EDI from your ERP vendor: start with Epicor EDI and ManagedXchange, which integrate with Kinetic and Prophet 21. If you are still choosing the ERP itself, see the 2026 manufacturing ERP comparison.
• You have integration skills and many partners, carriers and suppliers: look at a platform such as Cleo, OpenText Trading Grid or IBM Sterling, or Orderful if your team prefers working through an API.
• Most of your customers email PDFs or spreadsheets: EDI will not reach them. Add an order-entry tool, and keep EDI only for the partners who mandate it.
• You run several ERPs and only need order capture: a multi-ERP tool such as Conexiom may suit you better than anything built around one ERP.
• You run Epicor Kinetic and want the long tail drafted in Order Entry, with AP invoices or packing slips next: an agent such as Fluent covers those screens from one platform, alongside whichever EDI provider you choose.

Whatever you shortlist, test it on your own orders. For EDI, ask the vendor to show a live partner you trade with. For the long tail, send the messiest purchase orders you have: the customer who uses their own part numbers, the one who orders in cases while you sell in each, and the one who sends the same PO twice.

See it on your own orders

If Epicor Kinetic is your ERP, the order entry automation page shows how Fluent drafts sales orders, and the products page lists the other screens it covers. Plans are on the pricing page. You can book a demo and run it on a batch of your own PDF and email orders.
