If you are handling EDI for a manufacturing business and considering a move away from TrueCommerce, you are probably focused on minimising disruption, reducing costs, and making the transition as simple as possible for your team. The goal of this guide is to help you avoid hidden pitfalls and set up a migration plan that keeps your business running smoothly from day one.
⚡ Quick Answer
Migrating from TrueCommerce is achievable without contacting your trading partners, without downtime, and without rebuilding your ERP integrations from scratch — if you choose the right provider and follow a structured parallel-run approach. The biggest risks are underestimating what's flowing through your current setup and moving too fast without a pilot phase.
Executive Summary
- The most common TrueCommerce pain points are rising per-document fees, slow support, limited EDI visibility, and brittle ERP integrations as the business scales.
- The biggest migration risk is underestimating what's actually flowing — always pull 90 days of transaction logs, not just ERP data, before planning the switch.
- The best migrations require zero trading partner outreach — your new provider should handle all partner coordination on your behalf.
- A 2–4 week parallel run with defined success criteria is the industry standard for a safe, confident cutover.
- Manufacturers who have completed this switch report cost reductions of 50–83% versus their previous TrueCommerce billing.
Why Do Manufacturing Teams Rethink TrueCommerce?
Most teams start with TrueCommerce because it supports a wide range of protocols and offers out-of-the-box connections. Over time, several practical challenges typically surface:
- •EDI bills keep climbing — driven by mailbox, per-document, and protocol fees that compound as the partner network grows
- •Support tickets stack up, making simple map changes or new partner onboarding a weeks-long process
- •Limited visibility means your team discovers EDI errors after retailers do — triggering chargebacks that could have been prevented
- •ERP integrations with NetSuite, SAP, or Infor become brittle as the business scales and transaction volumes increase
- •Locked-in contracts limit flexibility and make it difficult to pilot alternatives without financial risk
What Are the 7 Most Common Pitfalls When Migrating Away from TrueCommerce?
1
Underestimating What Is Flowing Through Your Existing Setup
Many organisations think they have a simple setup — a handful of trading partners and key documents like 850 purchase orders and 810 invoices. Once you look closer, there are often forgotten flows: low-volume partners, seasonal spikes, or unique EDI specs for key customers.
- →Pull at least 90 days of EDI transaction logs from your existing VAN — not just ERP data
- →Create a partner profile for each connection: document types, monthly volume, unique requirements
- →Flag any partners with strict chargeback rules, custom test processes, or legacy protocols
2
Assuming Partner Outreach Is Required
A major blocker for many teams is the worry that you will need to re-onboard every trading partner. This can feel overwhelming when you're dealing with dozens of unique customer connections — but it shouldn't be necessary at all.
- →Require your new provider to migrate without changes from your trading partners — get this in writing
- →Confirm whether the migration involves updates to partner IDs, certificates, or testing on their side
- →Ask if onboarding for new partners is included at no cost going forward
3
Overlooking the Pricing Details
Many companies change providers only to find the same opaque billing and unexpected charges in a new wrapper. Pricing transparency is non-negotiable.
- →Break down your current bills: what are you actually paying per trading partner, per document, per protocol?
- →Ask providers for a complete cost breakdown using your actual last 3 months of data — not just a rate card
- →Watch for mailbox fees, protocol surcharges, and hidden costs for "premium" partner support
4
Overcomplicating ERP and Systems Integration
Most organisations run a mix of ERP, WMS, and shipping systems, and every extra manual step creates risk for IT and operations teams.
- →List every internal system that sends or receives EDI data: ERP, WMS, TMS, planning tools
- →Document all import and export flows for each system
- →Confirm your provider has live customers on your ERP version and handles map building as part of the service
5
Being Vague About Migration Success Criteria
Migrations are smoothest when you define your "done" criteria before the project starts, so there are no surprises about what it takes to cut off your old provider.
- →Set a required parallel run length — typically 14 days of dual processing on both platforms
- →Define acceptable error rates and SLAs for issue response during go-live
- →Build a rollback plan before you start — just in case
6
Underestimating the Need for Fast, Skilled Support
Support is easy to promise but hard to deliver — especially during migrations when high-volume partners or critical documents are involved.
- →Ask about support hours, escalation paths, and 24/7 incident handling — get specifics, not generalities
- →Request target response and resolution times for mission-critical flows
- →Talk to references with a similar partner and transaction mix before signing
7
Going Too Fast Without a Pilot Phase
Moving everything on day one sounds efficient but puts the most at risk. A time-bound pilot builds confidence and lets you verify that real-world flows are running smoothly before full commitment.
- →Select 2–4 trading partners of varying complexity and volume for your pilot
- →Monitor transaction success rates and support quality during the trial period
- →Use pilot learnings to set a realistic timeline for full migration

How Do You Structure a Smooth Migration Away from TrueCommerce?
Treat migration as a structured project with defined phases — not a single cutover event. The teams that struggle are the ones that try to move everything at once.
1
Understand Your Current Setup
Pull 3 months of EDI data and bills. List all partners, document types, and transaction volumes. Categorise by volume, EDI spec complexity, and chargeback sensitivity. Identify every system that touches EDI flows.
2
Screen Providers Against Your Actual Needs
Narrow to providers that match your ERP integrations, handle your transaction volume, and offer transparent all-inclusive pricing. Request references from companies your size. For most manufacturers, a focused VAN with clear ERP integration beats a general integration platform.
3
Plan the Parallel Run and Cutover
Set up new mailboxes and partner profiles. Build and validate your highest-volume document flows using real test data. Run transactions in parallel for 2–4 weeks and verify every document type processes without errors before rolling over traffic.
4
Confirm Internal Reporting and Teams Are Supported
Verify order and invoice data is appearing correctly for customer service, warehouse, and finance teams. Use your new portal to check real-time visibility and incident reporting before declaring the migration complete.
5
Shut Off the Old Platform When Ready
Once parallel-run targets are met and production flows are stable, cancel your old service and move your entire team to the new setup. Don't maintain both indefinitely — it adds cost and confusion.
Frequently Asked Questions
Migrating from TrueCommerce: Common Questions Answered
Do I need to contact my trading partners to migrate away from TrueCommerce?
+
No — with the right provider, your trading partners never need to know a migration is happening. The new provider takes over your existing mailboxes and partner configurations, so document flows continue without interruption. Always confirm this in writing before signing with any new EDI vendor.
How long does a TrueCommerce migration typically take?
+
Most migrations complete in days, with a parallel run of 2–4 weeks before full cutover. The timeline depends on the number of trading partners, ERP complexity, and how well-documented your current flows are. Manufacturers with clean data and a focused provider have completed full migrations in as little as 3 days.
Will migrating away from TrueCommerce affect my ERP integration?
+
Not if the migration is handled correctly. The best providers support direct integration with NetSuite, SAP, Infor, and Microsoft Dynamics and handle all EDI mapping on their side — keeping customisations out of your ERP. Confirm your new provider has live customers on your specific ERP version before committing.
How much can I realistically save by switching from TrueCommerce?
+
Manufacturers who have moved to flat per-partner pricing models report cost reductions of 50–83% versus their previous TrueCommerce billing. The savings come from eliminating per-document fees, mailbox charges, and protocol surcharges — costs that compound invisibly over time. The best way to quantify your savings is to share your current VAN bill with a prospective provider for a direct comparison.
What should I do first if I'm considering leaving TrueCommerce?
+
Pull your most recent 3 months of TrueCommerce bills and EDI transaction logs. This gives you an honest picture of your actual costs and flows — and is the single most valuable input for any migration conversation. From there, book exploratory calls with 2–3 providers and ask for a direct cost comparison using your real data, not a generic rate card.
