What EDI actually costs

Almost no EDI provider publishes pricing, which makes comparing quotes harder than it should be. This page explains the charging models, what genuinely drives cost, and the questions that expose the real number.

Three vendors, three quote formats, and no line items that line up. The ranges below are the ones we actually quote.

The four pricing models

Most quotes combine two or more of these. Knowing which you are being sold is half the battle.

Per document / per transaction

A price per EDI document sent or received, sometimes tiered by volume.

Works when
Predictable when volume is stable. Easy to model.
Watch for
Punishes growth. A busy season can produce an invoice nobody budgeted for.

Per kilocharacter

Billed on data volume rather than document count.

Works when
Fair when documents vary a lot in size.
Watch for
Almost impossible to forecast without historical data. A large ASN can cost several times a small purchase order.

Per trading partner

A monthly fee for each connected partner, often plus setup.

Works when
Clear, and scales with something you can count.
Watch for
Expensive if you have many low-volume partners. Watch what "setup" includes.

Flat platform or service fee

A fixed monthly amount, sometimes with a usage allowance.

Works when
Budgetable. Usually the model for managed services.
Watch for
The allowance is where the detail hides. Ask what happens above it.

What actually drives the number

In roughly the order they matter:

  • Number of trading partners. Each has its own spec, its own testing cycle, its own quirks. This dominates almost everything else.
  • Document volume. Matters most under per-document and per-kilocharacter models.
  • ERP integration depth. Dropping files in a folder is cheap. Writing sales orders directly into NetSuite or SAP with item cross-referencing is not.
  • Document mix. Purchase orders and invoices are straightforward. ASNs are where cost concentrates, because they have to describe physical reality.
  • How standard your partners are. A mainstream retailer using common specs is inexpensive. A partner with bespoke requirements can cost more than several standard ones combined.
  • Who handles exceptions. The cheapest quotes usually assume you do.

The questions that expose the real cost

Ask every provider the same five. The differences in their answers will tell you more than the headline prices.

  1. What do we pay at double this volume? Get the overage rate, not a reassurance.
  2. Is onboarding a new trading partner included? If billed, what is the typical figure?
  3. Is a map change support or a project? Partners change requirements regularly.
  4. What is the minimum term, and what does leaving involve?
  5. Who is accountable when a document fails outside business hours?

Where the cheapest option is genuinely right

If you have a small number of partners, low order volume, and someone with ten spare minutes a day, a web-forms product is the correct answer and integration would be an expensive mistake. We say that to people regularly. The break-even is real, and it is lower than most vendors would like it to be.

Why this page exists

Because searching for EDI pricing today returns software-comparison aggregators rather than anyone who actually does the work. That seemed like a gap worth filling, even though publishing it makes our own quotes easier to challenge.

Frequently asked

+ How much does EDI cost per month?

For a small supplier with a handful of trading partners and modest volume, a few hundred dollars a month is realistic. Mid-market companies with 10–40 partners and integrated ERP typically land somewhere in the low thousands. Large or complex environments run considerably higher: many partners, several ERPs, custom logic. Anyone quoting a single number without asking about partner count, volume and ERP is guessing.

+ What does EDI setup or implementation cost?

Implementation is usually a separate one-time charge covering connectivity, mapping, testing and partner certification. It commonly runs from a few thousand dollars for a simple first partner to considerably more for complex ERP integration. The variable that moves it most is how many partners you onboard at once and how far their requirements differ from standard.

+ Why will nobody publish EDI pricing?

Partly because it genuinely varies with volume, partner count and integration complexity. Partly because gated pricing creates a sales conversation. The practical effect is that buyers cannot compare offers without running a procurement exercise, which is why third-party aggregator sites rank so well for pricing searches.

+ Is web-forms EDI cheaper than integrated EDI?

Much cheaper to start, and genuinely right for low volumes. The crossover is usually somewhere between 20 and 50 orders a month. Past that, the labor cost of re-keying and the error rate typically exceed what integration costs to run. If you are re-keying orders into your ERP today, count the hours before assuming web forms are saving money.

+ What is the most commonly missed cost?

Transaction overage, followed by per-partner onboarding. The second one bites when sales closes a new retail account and the EDI setup fee arrives unbudgeted. Ask both questions before signing anything.
