Why Suppliers Are Leaving SPS Commerce — And What They Switch To

Switching EDI providers is a decision most suppliers approach with caution — the integration touches every retailer relationship, and a botched transition can disrupt live order flow. But suppliers do evaluate switching, and the reasons tend to be consistent across the conversations we’ve had with hundreds of companies who’ve made the move. Understanding what drives the evaluation helps you assess whether your current provider is serving you or whether it’s time to look at alternatives.

Cost Structure: Volume-Based vs. Flat Pricing

The most common trigger for evaluating a switch is cost — specifically, a pricing model where EDI costs scale with transaction volume. Many EDI providers, including large networks, use volume-based pricing: as your order volume grows, your per-transaction or tiered fees increase. The experience suppliers describe is a bill that grows faster than the value derived — a supplier who started at a modest monthly fee finds themselves paying significantly more as they’ve added retailers and order volume, without a corresponding change in the service level or support they receive.

The alternative model is flat monthly pricing — a fixed fee regardless of transaction volume. For growing suppliers, the difference is structural: volume-based pricing means your EDI cost is a variable expense that grows with your success; flat pricing means it’s a fixed operational cost that becomes proportionally smaller as you grow. When evaluating whether to switch, calculate your current monthly EDI spend (including all per-transaction fees, connection fees, and add-ons) and compare it to a flat-fee alternative. If the gap is significant and growing, that’s the signal.

Support Responsiveness

The second driver is support quality — and specifically, response time when something is broken. EDI issues are time-sensitive: an ASN that fails to transmit, a connection that goes down, a test transaction that’s stuck in a retailer’s review queue. When the retailer’s timing window is 30 minutes, a support response that takes days isn’t just frustrating — it’s a chargeback. Suppliers who switch providers frequently cite support responsiveness as a primary factor: the experience of opening a ticket and waiting days for a response, or being routed through tier-1 support who can’t actually resolve the issue, pushes them to look for a provider where they can reach someone who knows their account and their retailers directly.

When evaluating providers, ask specific questions about support: Who do you reach when you call? Is it a general support line or someone with EDI expertise? What’s the typical response time for a live transmission failure? The answers tell you whether the provider’s support model matches your operational needs.

Contract Flexibility

The third driver is contract structure. Annual contracts with early termination fees are standard at many large EDI providers — and for a supplier who’s evaluating alternatives mid-contract, the termination fee is a barrier to switching even when the service isn’t meeting expectations. Suppliers who value flexibility — the ability to evaluate a provider on an ongoing basis and switch if the relationship isn’t working — look for month-to-month options without lock-in.

When evaluating providers, the contract terms are as important as the feature list. A provider that offers month-to-month terms is signaling confidence in their service; a provider that requires annual commitment with termination fees is signaling that retention depends on the contract, not the service.

What to Evaluate When Switching

If you’re considering a switch, evaluate alternatives on the dimensions that drove the evaluation:

• Pricing model — flat monthly fee vs. volume-based per-transaction pricing. Calculate your total current monthly cost and compare.
• Support model — direct access to EDI expertise vs. tiered support queues. Ask for specifics, not promises.
• Contract terms — month-to-month vs. annual with termination fees.
• Transition support — does the new provider handle the migration of your trading partner connections, or are you on your own? A provider that manages the transition minimizes the risk of disrupted order flow during the switch.

Making the Switch

Switching EDI providers sounds daunting, but a provider with a structured transition process can migrate your trading partner connections without downtime. The key is that the new provider handles the connection migration, retailer-spec configuration, and testing — you shouldn’t be rebuilding your EDI setup from scratch. Spring Systems has a dedicated onboarding process that migrates all your trading partner connections and gets you live on the new platform without missing a beat in your order flow.
