EDI Myths: 9 Common Misconceptions About EDI, Busted
Nine things people still believe about EDI, from unavoidable VAN charges to 'it only does orders and invoices', and what is actually true today.
EDI has been around since the 1970s, and a lot of what people still believe about it dates from that era. Modern cloud EDI works very differently, yet old assumptions about cost, complexity and relevance still shape buying decisions, and some legacy providers still profit from them.
What are the most common EDI myths?
The most common EDI myths are that VAN charges are unavoidable, that EDI is too expensive, outdated, complicated or needs dedicated software, that it comes built into an ERP or iPaaS layer, and that it only handles orders and invoices. Modern cloud EDI disproves each one. Two claims, faster order-to-cash and better partner relationships, hold true only with the right setup.
Here are the nine myths we hear most often, and what is actually true today. Two of them are partly true, and we say so.
Myth 1: VAN charges are an unavoidable cost of EDI
Value added network (VAN) charges are a feature of legacy pricing, not of EDI. They make EDI costs hard to forecast, and they penalise growth: the more you trade, the more you pay.
The small print adds to the bill. Some providers set a minimum record length of 128 to 512 characters, so ten documents of ten characters each can be billed as up to 5,120 characters, even though only 100 were sent. For a business with many small transactions, that adds up fast. Folding VAN charges into a subscription or a pay-as-you-go plan hides them without removing them, and can lock a business into an expensive contract when its circumstances change.
Transalis removes VAN charges entirely, so costs stay consistent as trading volumes grow and forecasting becomes simple.
Myth 2: EDI solutions are too expensive
EDI has a reputation for unexpected and rising costs, mostly because some providers wrap it in complexity: set-up fees, charges per message type and charges per transaction.
It does not need to work that way. Transalis prices EDI as a transparent, predictable subscription rather than charging per message type or per transaction, which makes it easy to buy and simple to switch to.
To judge the return, start with the time your team spends today on orders, invoices, advance shipping notices and delivery notes. The biggest gains usually come from removing double keying and the data entry errors that follow it.
Myth 3: EDI will speed up your order-to-cash cycle (partly true)
This one is half right. EDI on its own cannot change the payment terms between a supplier and a retailer, and it cannot make a trading partner pay the moment an invoice arrives.
What it does is remove the admin bottlenecks between order and invoice. Systems exchange documents directly and automatically, so orders, confirmations and invoices move far faster than they do through spreadsheets and email, and they are right first time. That puts everything in place for timely payment.
Adding eInvoicing takes it further, with invoice validation, time stamping, automatic archiving and regulatory compliance. Some trading partners even offer a discount for electronic invoicing, because it speeds up their own processing.
Myth 4: EDI is outdated
EDI dates from the 1970s, which makes it mature and widely trusted, not obsolete. It has kept evolving, and cloud technology has made it more relevant and cost-effective than ever.
Cloud EDI needs no on-premise hardware and no paid upgrades. Real-time data is visible on a dashboard from any device, new trading partners can be onboarded quickly, and integration options often come ready to use, so expensive in-house translation software can be retired. Modern platforms support any data standard or format, and can handle integrations that were not possible before.
APIs have not replaced it either: the strongest supply chains run EDI and APIs side by side.
Myth 5: You need dedicated software to run EDI
Leading EDI services are now cloud-based, so there is no EDI software to install, no IT integration project to run and no complex middleware to buy.
The provider handles implementation and ongoing maintenance in the cloud with minimal disruption, and keeps the service up to date. You avoid hardware and software maintenance costs, you do not need to hire EDI specialists, and business continuity and disaster recovery are stronger.
Myth 6: EDI is unnecessarily complicated
This myth has put many SMEs off EDI. In practice, EDI simplifies trading. The documents and formats trading partners use vary enormously, and a good EDI service standardises them, so every partner can trade with you without friction.
Cloud delivery has also simplified implementation. The provider does the set-up and the maintenance, and moving from an in-house EDI system to a cloud service reduces cost while improving security, scalability and throughput.
Myth 7: EDI adoption improves relationships across your trading network (partly true)
True, but only when your trading partners are on EDI too. If one partner still handles orders by hand, the whole chain waits until that paperwork is done. With automation, documents move instantly, around the clock.
So the real work is adoption: building a critical mass of partners who trade electronically. Transalis runs a fully supported onboarding and adoption programme, with a white-label partner registration page, outreach to your trading partners, and training that includes guides and walk-through videos. Once connected, your partners exchange documents with you in real time, and can use EDI with their own supply chains too.
Myth 8: EDI is included in my ERP or iPaaS integration layer
The EDI option bundled with an ERP is usually legacy middleware. It is not agile, it needs in-house people with the right skills to configure and maintain it, and it often forces your trading partners to change their own EDI processes to match yours.
iPaaS bolt-ons can support EDI, but you still have to configure the ecosystem yourself, which takes EDI expertise that is increasingly hard to find. Gartner has recommended a hybrid approach instead: use the integration layer to orchestrate internal data flows, and plug in an established EDI platform to connect your trading network. That route tends to deploy faster and needs less investment.
Myth 9: EDI is only good for orders and invoices
Modern EDI platforms support hundreds of document types, many of them specific to a function, sector or industry, including the messages for import and export customs procedures.
The documents behind everyday supply chain, ecommerce and dropship trading include inventory status, purchase orders and acknowledgements, advance shipping notices, purchase order changes and invoices. Beyond those sit returns authorisations, credit and debit adjustments, requests for quotation and price information, and specialist messages such as waste disposal information.

Frequently asked questions
- Are VAN charges necessary for EDI?
No. Value added network charges come from legacy pricing models, not from EDI itself. They are often billed per character with minimum record lengths, which makes costs hard to predict and penalises growth. A provider that does not charge VAN fees keeps EDI costs consistent as trading volumes rise, so budgeting is far simpler.
- Is EDI still relevant now that APIs exist?
Yes. EDI is still how retailers, manufacturers and logistics providers exchange orders, invoices and shipping notices at scale, and cloud platforms have modernised how it is delivered. APIs suit real-time connections, while EDI suits structured document exchange across large trading networks, so leading businesses run both side by side.
- Do I need in-house EDI experts to run EDI?
Not with a managed cloud EDI service. The provider handles implementation, maintenance and updates, so you need neither specialist EDI staff nor your own EDI software. That matters because EDI configuration skills are increasingly scarce, which is one reason ERP and iPaaS add-ons that you configure yourself can become a burden.
- Does EDI make customers pay faster?
Not directly. EDI cannot change agreed payment terms, but it removes the delays between order and invoice, so invoices arrive sooner and without errors. Combined with eInvoicing features such as validation and time stamping, it makes timely payment much more likely, and some trading partners offer a discount for electronic invoicing.
