The defensible answer
Short answer: SignalEDI publishes plans at $99–$1999/mo; buyers evaluating cloud EDI commonly see market quotes in a $300–$3000/mo range. There is no honest universal price beyond that — cost depends on the pricing unit—flat subscription, trading partner, document, data volume, or services—as well as your partner count, document mix, integrations, testing scope, support, and contract terms. Compare any quote against the published EDI pricing table with the worksheet below.
SignalEDI publishes four monthly software plans: Seasonal $99, Starter $199, Growth $999, and Enterprise $1999. Seasonal includes a published $20/month dormant mode for keeping partners, mappings, and history configured between active periods. Review the live EDI pricing page for current entitlements and terms.
Current public pricing evidence
The following source review was refreshed on August 12, 2026:
| Vendor or model | What the official public source supports | What remains unknown |
|---|---|---|
| SignalEDI | Four published monthly tiers: Seasonal $99, Starter $199, Growth $999, Enterprise $1999 | Your required add-ons and implementation scope |
| Orderful Web EDI | The official pricing page lists $189/month per trading partner | Your partner count, product fit, services, and total term |
| SPS Commerce Fulfillment | The official Fulfillment page describes full-service EDI and invites a demo | One universal public rate card was not displayed on the reviewed page; request a written quote |
| Stedi | The official pricing page publishes transaction-type and volume tiers | Your exact transaction mix and volume; do not reduce the schedule to one generic per-document rate |
| Other quote-led vendors | A proposal may define subscription, implementation, and services | Everything not written in the current proposal |
This table deliberately does not repeat old marketplace estimates, customer anecdotes, or unsupported contract claims as vendor facts.
A twelve-month EDI cost worksheet
Compare each vendor with the same equation:
Annual EDI cost = subscription + partner charges + usage charges + implementation + mapping changes + connectors + support + seasonal idle cost
Record these inputs:
- Active months and idle months.
- Number of trading partners or payers.
- Monthly documents by type: 850, 855, 856, 810, acknowledgements, or healthcare transactions.
- Required QuickBooks, ERP, WMS, or API connection.
- Implementation, mapping, testing, and training services.
- Support level, response targets, overages, renewal, and exit terms.
Self-serve onboarding is included on paid SignalEDI plans, with managed onboarding available as a paid add-on when a team wants hands-on launch support. Include that optional service in the worksheet only when it is actually in scope.
Use the EDI cost calculator to model only vendors with enough published evidence. Vendors without sufficient current evidence remain visibly not modeled instead of receiving an invented midpoint.
When the $99 Seasonal plan changes the math
A seasonal supplier can be poorly served by a year-round cost comparison. Model active and dormant periods separately.
For example, if the public terms still fit your workload, four active months on Seasonal plus eight dormant months would use this software-price calculation:
(4 × $99) + (8 × $20) = $556/year
That is a plan-price illustration, not a quote for implementation, add-ons, partner approval, or a specific retailer program. Validate transaction volume, partner count, retention, and connection requirements before choosing it.
What belongs in a current vendor quote
Ask every vendor to put the following in writing:
- Product and plan name.
- Billing cadence and contract term.
- Included partners, documents, users, and volume.
- Implementation, mapping, testing, and training fees.
- QuickBooks or ERP connector scope.
- Support and service-level commitments.
- Overage, renewal, change-request, and exit terms.
If a row is absent, mark it unknown. “Typical” is not a contractual price.
Cost is not the only readiness gate
The cheapest subscription can still fail the mandate if the partner packet, identifiers, pack hierarchy, acknowledgements, or test evidence are incomplete. Start with the customer requires EDI guide, then run the requirements checker before committing to a plan.
For small-business product fit, continue to EDI software for small business. For QuickBooks intent, use the QuickBooks EDI guide. If a partner is asking about APIs instead of documents, read EDI vs API before you choose.
