EDI software is an application that moves purchase orders, invoices, and similar documents between your systems and your trading partners' systems, and nobody must retype them. It translates your data into an agreed format like ANSI X12, checks it, and sends it.
This article walks through how EDI software works, the main types, what drives the cost, and many more.

How EDI Software Works
As we know, email is electronic, but somebody still opens the attachment and keys the order in by hand. EDI gets rid of that person's job, at least that part of it. The document goes straight into the receiving system, an order management system, for example.
Along the way, the software maps your item numbers, addresses, and quantities into the layout the partner expects, validates the file, sends it, and tracks the acknowledgement coming back. Delivery happens point-to-point or through a value-added network (VAN) over secure protocols such as AS2 or SFTP.
Before any of that, both sides must agree on a standard and a version. ANSI X12, or EDIFACT. If those do not match, the receiver cannot read your file. That's it, that's the whole failure.
Now the question arises: where do you feel the difference?
Between sales and the warehouse, mostly. When a purchase order drops into the order system untouched, both teams are looking at one record. The arguments over quantities and ship dates get a lot smaller, and those arguments are worse in peak weeks, exactly when nobody has time for them.
Examples of EDI Documents
A few documents carry most of the traffic. The 850 is the purchase order, the 810 is the invoice, the 856 is the advance ship notice, and the 820 carries payment instructions. The 846 reports inventory, and the 214 gives shipment status.
In a retail cycle they go in a set order. The buyer sends the 850. The supplier sends the 856 before the truck gets to the distribution centre, then the 810 follows. Timing is strict. Canadian Tire, for one, wants the ship notice in hand before the shipment shows up.
Why EDI Software Matters for Canadian Businesses
Once your order volume passes a certain point, the big retailers stop treating EDI as optional. Canadian Tire requires all its vendors to use it. One integrator's guide lists Loblaws, Sobeys, Metro, Walmart Canada, and Costco Canada as making it mandatory above a certain volume. These retailers run ANSI X12, the usual North American format, and EDIFACT is the international one. If you ship from Vancouver or Calgary into Ontario and the US, X12 will likely be the first you meet.
Tax and record keeping come into it as well. The CRA expects you to keep records from computerized systems, electronic purchasing, and restocking systems included, for six years, and to hand them over when asked. Contracting out your record keeping does not contract out the responsibility. So, ask any EDI provider where your archive sits and how you'd get it out again.
Invoices need a closer look. Where GST/HST is charged on a supply of CAD $30 or more, the supplier must show its registration number on the supporting document, since buyers lean on it for input tax credits. Your 810 mapping must carry those fields. It also must deal with Ontario's HST, Alberta's GST-only treatment, British Columbia's separate PST, and Quebec's QST. A generic template tends to trip on at least one of those.
Canada has no B2B e-invoicing mandate, although the CRA is studying e-invoicing for GST/HST compliance. For now, it's customers who push EDI adoption here. Not legislation.

Types of EDI Software Solutions
Buyers usually end up choosing between four setups. Such as:
| Setup | Suits | Watch for |
| Cloud-based EDI software | Growing suppliers with several partners | Fees rise with partners and volume. |
| Web EDI portal | Small suppliers with one or two retailers | Manual keying unless linked to your ERP |
| On-premises | Firms needing full control and in-house IT | Hardware, upgrades, and staffing |
| Managed EDI service | Teams without EDI skills | Less control, more vendor dependence |
G2 shifts from on-premises to cloud because owning hardware and maintaining legacy software adds cost and makes scaling harder. The category is crowded. Capterra Canada spreads its EDI listings over nine pages, and G2 tracks 163 products as of October 2026.
Plenty of those are integration platforms where EDI is one module among many. Fine, until a retailer sends you a strict implementation guide and you find out the module can't follow it. So before shortlisting any B2B EDI software, confirm it handles X12 mapping and partner-specific validation natively.
Features to Look For
Mapping and translation first, because every partner has its own spec. Partner onboarding tools right after. The software itself rarely slows you down. What do the weeks of test files mean for going back and forth with each retailer?
Validation gets its own question. G2 requires products in its EDI category to check documents against the standard and against the partner's specification and to flag errors and missing information. An error that reaches a retailer can turn into a chargeback, and Cleo positions early error resolution as the way to head that off. A faster translator is nice. Catching a bad file before it leaves is better.
Beyond these core capabilities, look for transaction monitoring with alerts for failed transactions, AS2 and SFTP support, access controls, and an ERP connector. For decentralized finance teams, the ERP connector is especially important because it consolidates branch-level invoices and EDI payment into one system. APIs support real-time application integrations, but major retailers often still require vendors to exchange transactions through EDI, which is why many platforms now support both technologies.
EDI ERP Software and Microsoft Dynamics 365
An EDI tool that cannot post into your ERP software just moves the typing somewhere else. This is why ERP integration usually decides an EDI project more than the translator does.
Take branch accountants in Toronto, Vancouver, and Calgary, each handling their own receivables. On an ERP, they share one ledger and one set of tax codes, so an EDI invoice from any branch gets the same GST/HST or PST treatment. Without that, partner documents pile up in spreadsheets, and the head office untangles them at month-end. Slow, and it shows up on the close.
Dynamics 365 handles EDI differently by product. Business Central's E-Documents feature connects to external access points such as Pagero, Avalara, and B2B Router, with more connectors on AppSource.
Business Central EDI typically runs through AppSource extensions or connector platforms. TrueCommerce, for instance, offers a cloud connection with transaction visibility inside Business Central, and Cleo and iEDI both list Business Central support. Furthermore, for Finance and Operations, Microsoft's training material points to an EDI module on AppSource.
Every vendor says it integrates with Dynamics 365. What separates them is depth and what happens when a sync fails. Ask for a demo with your own items, price classes, and tax codes. A Business Central Partner in Canada like Dynamics Square can help you run that test before the contract is signed, which helps on Business Central Canada rollouts, where tax codes differ by province.
EDI Software Cost
EDI software cost is rarely one number. There is a platform subscription, a setup or mapping fee for each trading partner, network charges if a VAN is involved, and support or managed-service hours on top.
The per-partner fees are the ones that surprise people. One comparison site warns that SPS Commerce's published tiers understate the real cost, since contracts add per-partner setup fees. A Dynamics 365 add-on vendor tells buyers to budget separately for an EDI gateway or VAN and for per-message costs.
With that, deployment changes the shape of the spending. Cloud EDI is a subscription that grows with your volume. "On-premises" means paying for hardware upfront. Walmart Canada and Home Depot Canada accept direct AS2 connections without a VAN, which can cut a per-retailer fee, though certificate management and uptime become your problem.
How to Choose and Implement
Start with the retailer's requirements. Not the vendor list. Write down each trading partner, the documents they require, the standard and version, and the go-live date.
Then be honest about how much EDI work your own team can take on. A small in-house team points to a managed service or Web EDI. A growing partner network points to cloud-based EDI software with an ERP connector, and if your finance is decentralized, to an ERP that gives the head office one view of invoices and remittances by branch.
G2 suggests shortlisting three to five vendors, giving each the same use case and data in a demo, and piloting with a small group before committing. Add two Canadian checks to that: where the archive is hosted for CRA purposes and whether invoices carry your GST/HST and PST fields correctly.
Pilot with one retailer first. The first partner shows you the mapping gaps early, while they are still cheap to fix.
Final Thoughts
As we discussed above, order of work matters here. Retailer requirements first, then ERP fit, then vendor and price. Dynamics Square Canada helps mid-market teams running Business Central in Toronto, Ontario, and British Columbia check that fit before anything is signed.
