The EDI server in the back room has been running since 2012. It needs a security patch nobody wants to install on a Friday, the consultant who built the maps has moved on, and your biggest retailer just sent a new version of its 856 specification.
Cloud-based EDI moves that whole stack (translator, maps, network connections) to a provider’s hosted platform, so your team sends and receives EDI documents over the internet and someone else keeps the servers, updates and trading partner connections running.
So is it the right move for your company, or just a different set of trade-offs?
In this guide, you’ll learn:
- what cloud-based EDI is, and how it differs from web EDI and managed EDI;
- how a cloud EDI transaction travels from your trading partner to your ERP;
- the real differences between cloud and on-premises EDI in cost, control and scalability;
- how to judge a cloud EDI provider on security, integration and support.
What is cloud-based EDI?
Cloud-based EDI, sometimes called internet EDI or EDI in the cloud, is electronic data interchange delivered as a hosted service. The NIST definition of cloud computing (SP 800-145) describes on-demand network access to shared, configurable computing resources that are provisioned with minimal management effort; applied to EDI, the provider runs the EDI software and infrastructure, and you use it as software as a service (SaaS).
Every cloud EDI solution combines three parts.
An EDI translator handles the data transformation between your ERP’s flat file or API output and standards such as ANSI X12, EDIFACT or XML-based formats. A network connects you to trading partners over a value-added network (VAN), a multi-enterprise network or direct protocols like AS2, AS1, AS3, HTTPS, FTP and FTPS. And a provider maintains both, usually on a multi-tenant platform shared by many customers.
Cloud EDI, web EDI and managed EDI
The terms overlap, but they describe different levels of service. Web EDI, or web-based EDI, is cloud EDI you use through a browser: you key in or review documents on a portal, which suits low volumes. Integrated cloud EDI connects the hosted platform directly to your ERP, so documents flow without manual data entry. Managed EDI adds people: the provider also builds your maps, onboards trading partners and monitors transactions for you.
How cloud EDI works, step by step
Take a retail purchase order. Your customer’s system sends an EDI 850 purchase order over AS2, SFTP or a VAN to your cloud EDI provider, which returns a 997 functional acknowledgment to confirm receipt. The platform translates the 850 and delivers it to your ERP as a sales order, or displays it on the web portal if you are not integrated yet.
From there the flow reverses. Your ERP produces the 855 PO acknowledgment, the 856 advance ship notice matched to the GS1-128 shipping labels and the 810 invoice, and often an 846 inventory update; the cloud platform maps each one to the retailer’s specification, checks it for EDI compliance and sends it over AS2 or the VAN. Every step is logged, so you can trace any document from receipt to delivery.
Cloud-based EDI vs on-premises EDI
With on-premises EDI, you buy or license the software, install it on your own servers and staff the people who maintain maps and connections. With cloud-based EDI, the provider owns that infrastructure and you pay for access. Neither is right for everyone; the differences come down to five points.
| Cloud-based EDI | On-premises EDI | |
|---|---|---|
| Cost model | Monthly or annual subscription | Upfront licence, servers and IT staff |
| Maintenance | Provider applies software updates | Your team patches and upgrades |
| Scalability | Add trading partners and volume on demand | Limited by your servers and staff |
| Control | Provider controls the platform | Full control of software and data |
| Setup | No hardware to install; partner testing sets the pace | Hardware, installation, then partner testing |
Cost: subscription versus upfront investment
On-premises EDI means capital costs before the first document is sent: licences, servers, backups and the in-house team to run them. Cloud EDI turns that into a subscription that usually scales with the number of trading partners and transaction volume. Compare the total cost of ownership over three to five years, including staff time, rather than the first-year price alone.
Maintenance and software updates
Retailers revise their EDI specifications, standards publish new versions and security patches never stop. On a cloud EDI platform, the provider handles those updates centrally, and a change to a common retailer map can often be reused across the customers who trade with that retailer. On premises, each update is a project for your IT infrastructure team.
Scalability for seasonal transaction volume
A supplier that ships twice as many orders in the fourth quarter needs capacity for the peak, not the average. Cloud EDI scales with transaction volume because the provider pools resources across customers and adds capacity on demand, what NIST calls resource pooling and rapid elasticity. Adding a new trading partner is a mapping and testing job rather than a server purchase.
Control, customization and vendor lock-in
The main trade-off of cloud-based EDI is less direct control. You depend on the provider’s platform, its release schedule and its uptime, and switching EDI providers later means migrating maps and partner connections. Ask who owns your maps, what a service level agreement (SLA) guarantees and how data is exported before signing.
Hybrid EDI models
Some companies keep translation in-house for a core ERP and use a cloud provider for network connectivity, or run a new division on cloud EDI while the legacy system stays on premises. A hybrid model makes sense during a migration or when a few partners need custom processing, but it means two systems to monitor.
Is cloud-based EDI secure?
A cloud EDI provider handles purchase orders, prices and customer data, so its security controls matter as much as its features. The strongest evidence is an independent audit: a SOC 2 report under the AICPA Trust Services Criteria covers security and, optionally, availability, processing integrity, confidentiality and privacy, and a Type 2 report tests those controls over a period of time rather than on one day.
On the transmission side, look for encryption in transit and at rest, AS2 with signed MDN receipts for non-repudiation, role-based access controls and documented disaster recovery with backups. Canadian companies may also want to know where their data is hosted, since data residency can matter for privacy obligations under PIPEDA.
Who should use cloud-based EDI?
Cloud-based EDI fits small and medium businesses, especially suppliers that receive their first EDI mandate from a retailer and have no in-house EDI team. It also fits growing companies whose trading partner list, order volume or ecommerce channels (Shopify, Amazon) are expanding faster than an on-premises system can follow. Companies on cloud ERPs such as QuickBooks Online, NetSuite, Acumatica or Microsoft Dynamics 365 Business Central tend to prefer an EDI platform that runs the same way, with real-time visibility on orders across the supply chain.
On-premises EDI still makes sense for large enterprises with a dedicated EDI team, strict internal hosting rules or heavy custom processing across SAP, a WMS and a TMS. Even then, many of them outsource the network connections to a cloud provider and keep only translation in-house.
How to choose a cloud EDI provider
Features look alike on every provider’s website. These five checks separate them.
1Cloud EDI integration inside your ERP
Check whether the provider integrates EDI inside your ERP, through a native app or an API, or only exports files you import yourself. An embedded integration is what removes manual data entry; a portal alone moves it to a different screen.
2Networks and protocols the provider supports
Your trading partners decide the protocol. A provider should support AS2, VAN connectivity and the partners you already trade with, and handle the 997 and 999 acknowledgments that confirm each file. For AS2, Drummond interoperability certification is a useful signal; for the hosting side, look for SOC 2 or ISO 27001.
3Mapping and trading partner onboarding
Some cloud EDI software gives you the tools and leaves the mapping to you. A managed provider builds and tests each map, onboards new trading partners and fixes rejected documents, which is usually the deciding factor for small teams.
4Cloud EDI support and response time
Find out who answers when an 856 is rejected at 4 p.m. on the last day of the quarter: a ticket queue or a named person who knows your setup. Response time on errors is what protects you from chargebacks.
5Transparent cloud EDI pricing
Ask how the subscription scales with trading partners, documents and transaction volume, what onboarding a new partner costs and whether support is included. A clear pricing model makes total cost of ownership easy to compare with an on-premises system.

Cloud-based EDI is electronic data interchange delivered as a hosted service. The provider runs the EDI translator, the maps and the connections to trading partners on its own infrastructure, and you send and receive documents over the internet, through a web portal or an integration with your ERP. You pay a subscription instead of buying and maintaining EDI software and servers yourself.
Cloud EDI runs on the provider’s infrastructure and is paid by subscription; the provider handles software updates, maintenance and network connections. On-premises EDI runs on your own servers, with an upfront licence and an in-house team to maintain it. On premises gives more direct control, while cloud EDI is faster to set up and scales more easily with transaction volume.
Web EDI is one form of cloud EDI. It gives you a browser-based portal to read incoming orders and create responses such as ship notices and invoices, usually by keying data in. Integrated cloud EDI goes further and connects the hosted platform directly to your ERP, so documents are created and posted automatically without manual entry.
Cloud EDI can be as secure as an on-premises system when the provider encrypts data in transit and at rest, controls user access and holds an independent audit such as a SOC 2 Type 2 report. Ask for the report, the disaster recovery plan and details on where data is hosted before choosing a cloud EDI provider.
Most cloud EDI providers charge a subscription based on the number of trading partners, the documents exchanged and transaction volume, with setup fees for mapping and onboarding. Web EDI costs less to start; ERP-integrated and fully managed EDI cost more but remove manual work. Compare total cost of ownership, including staff time, rather than monthly fees alone.
Most cloud EDI platforms can connect to an ERP, but the depth varies. Some provide native apps that run inside the ERP, others use an API or scheduled file exchanges; in practice, the EDI vs API question is rarely either-or, and most B2B integration mixes both. Vantree embeds EDI in more than 35 ERP systems, including QuickBooks, NetSuite, Acumatica, Sage and Microsoft Dynamics 365 Business Central.
Yes, and they are often the ones who benefit most. A small supplier that receives its first EDI requirement from a retailer can start on a web EDI portal with no IT infrastructure, then move to an ERP integration as order volume grows. The provider sets up each trading partner’s specification and validates documents against it.
Start by listing your trading partners, the documents each one requires and your current maps. The new provider rebuilds or imports the maps, tests with each partner and switches connections over one partner at a time, so orders keep flowing during the migration. Plan the switch outside your peak season.
