The most practical EDI alternative for customers who will never connect is to accept their orders the way they already send them, by email, PDF or spreadsheet, and have an AI agent read each one, check it against your ERP and create the sales order. The customer changes nothing, and your order desk stops retyping.
At Lleverage we think the search for an EDI alternative usually starts with the wrong question. Suppliers ask how to get more customers onto a structured channel. The customers in question have already answered: they order by email because it works for them, and a portal invitation rarely changes that. The useful question is what happens on your side once the email lands.
We build AI agents for order processing in the ERP you already run, for companies that make, move and sell physical products. This article compares the alternatives to EDI for the customers who will never use it, says what each one asks of the customer, and covers order entry into SAP without EDI. If you want to see it on your own inbox, book a demo.
Why will some customers never do EDI?
Because the setup cost falls on them and the benefit falls mostly on you. EDI needs a message standard, a mapping between both catalogues, testing and someone to maintain the connection. A customer ordering 4 times a month rarely funds that, and many small firms have nobody to run it.
The public numbers say the same. According to Eurostat's 2025 survey of EU enterprises with 10 or more employees, 5.6% made sales through EDI-type messages. Among firms with 10 to 49 people the share was 3.75%. Among firms with 250 people or more it was 27.81%. EDI lives at the large end of the market, and the long tail of your customer base sits at the other end.
That is why EDI coverage stalls. The large accounts connect, the rest keep emailing, and every new customer you win starts on email too. Our piece on EDI order processing in 2026 sets out which orders EDI covers and why the remainder is the harder half. This article is about that remainder: the customers for whom EDI is off the table.
What are the alternatives to EDI for B2B orders?
There are 5 common EDI alternatives for customers who will not connect. You can keep keying orders by hand, offer web EDI, open a B2B web shop or customer portal, capture orders with OCR templates or an ERP's own extraction feature, or put an AI agent on the inbox. They differ mainly in who does the work: your customer or your desk.
Manual entry. The default. Someone reads the email, opens the ERP and types. It costs nothing to start and scales only with headcount.
Web EDI. The supplier, or an EDI provider, gives the customer a web form that produces an EDI message on the other side. Your system receives structured data. The customer now retypes their own order into your form, which is the work you wanted gone, moved to them.
A B2B web shop or customer portal. Customers log in, find items and place the order themselves. This suits repeat buyers of standard catalogue items. It suits customers less when they order by project, by their own part numbers or by a description only the desk understands.
OCR templates and ERP extraction features. Software reads a PDF purchase order into fields, usually with a template per customer layout or a review step before the order exists. It helps with clean, consistent PDFs. Email body text, spreadsheets and orders with no article numbers tend to fall back to the desk.
An AI agent on the order inbox. The agent reads whatever arrives, matches the customer and each line against your master data, checks price, stock and credit, and creates the sales order. Orders outside your rules go to a person with the reason attached. Nothing changes for the customer.
How do the EDI alternatives compare?
The fair comparison is what each option asks of your customer, what it asks of your desk, and which orders it leaves behind. The table below sets that out for the 5 alternatives and for EDI itself, so you can see where each one fits rather than which one wins.
| Option | What the customer does | What your desk does | Orders it leaves behind | Fits best when |
|---|---|---|---|---|
| EDI | Builds and maintains a connection | Maintains mappings per partner | Every customer not connected | A few large accounts send high volume |
| Manual entry | Nothing new | Reads and keys every order | None, at the cost of hours | Very low volume |
| Web EDI | Retypes the order into your form | Little, once data arrives | Customers who refuse the form | A large buyer can require it |
| B2B web shop or portal | Logs in and orders from your catalogue | Handles the orders that bypass it | Project orders, own part numbers, urgent changes | Repeat orders of standard items |
| OCR templates or ERP extraction | Nothing new | Uploads, reviews and corrects | Spreadsheets, email text, unknown layouts | Consistent PDFs in modest numbers |
| AI agent on the inbox | Nothing new | Handles the exceptions it is given | Orders outside your rules, flagged with a reason | Many customers, many formats |
Two points sit behind the table. First, these options combine: a supplier can keep EDI for the accounts that justify it and add one of the others for everyone else. Second, every option that asks the customer to change has a ceiling, set by how many customers agree to it. An option that asks nothing of the customer has no such ceiling.
Which EDI alternative works for customers who order by email?
For customers who order by email, the alternative that sticks is the one that reads email. Portals and web EDI only work for customers who agree to use them, and the customers in this group have already shown they will not. An AI agent reading the inbox takes their orders in the form they send.
The order that arrives this way is rarely tidy. At SIG Benelux, a building materials distributor, around 3% of orders carry an article number and roughly 47% have only a description. The rest arrives as a WhatsApp message, a photo pasted into an email or a sentence that only makes sense if you know the customer. Today 73% of order emails reach Dynamics 365 on their own as a draft order, and order lines match the correct article first time on 88% of lines, using years of order history as the rulebook.
At Topa Bathroom Products, a wholesaler serving around 700 customers, orders arrived as plain text emails, PDFs, CSVs and Excel sheets, each in the customer's own format. Over 90% of incoming orders are now processed into Business Central without manual input, and some customers receive their order confirmation within 30 seconds. Koninklijke Dekker, a timber business of more than 140 years, set the goal plainly: reduce the manual work without forcing customers to change how they submit their orders.
"You deliberately leave questions unasked, because asking makes the processing take longer. You would want to ask, but there is no time. That is being made possible now." Patrick Wijers, Sales Desk Manager, SIG Benelux
That quote is the cost manual entry hides. Retyping takes the time the desk would otherwise spend talking to customers.
Which vendors automate order entry into SAP without EDI?
There are 3 routes into SAP for orders that do not come by EDI: SAP's own extraction feature, order automation software that writes into SAP, and RPA bots that key orders through the screen. The test for any of them is whether it checks each order against SAP before the sales order exists.
SAP's own route is described on its product page for S/4HANA Cloud Public Edition, read on 16 October 2026: a sales representative uploads a purchase order file in PDF or image format, and the system extracts it into a sales order request that can later be converted into a sales order. That works when orders arrive as PDFs and a person reviews each one anyway. It does not pick orders up from the inbox, and spreadsheets and email text are not among the formats it names.
Our SAP order automation takes the other route. The agent picks the order up from the shared inbox, finds the sold-to and ship-to party and the materials, including lines that carry the customer's own part number, and checks price, quantity and delivery date before it creates the sales order. It works with SAP S/4HANA and SAP ECC, and Lleverage is SAP-certified. Customers who already send EDI or IDocs keep doing so. That page compares the two routes line by line.
What should an EDI alternative check before the order reaches the ERP?
An EDI alternative should check the same things your order desk checks: the customer, every article, the price against contract, stock and the requested date, and credit status. EDI orders arrive pre-agreed. Emailed orders do not, so the checks have to happen on your side before the sales order exists.
The design point that matters is where the line sits between what the agent completes and what a person sees. In our setup every check has its own setting. Orders inside your rules are created and confirmed on their own. A price off contract, an unknown article or a credit hold waits for the person you choose, with the reason attached. Changes take effect on the next order and are logged with who made them.
The other check is the ERP itself. The agent fills the same fields your desk fills, so the ERP validates them the same way. Nothing is migrated into a second database. At Microtechniek, whose on-premise Ridder IQ had no way in for outside systems, around 60 orders a week now land in the ERP without anyone typing them. Each used to take about 10 minutes by hand, and the desk has more than 500 hours a year back. Our ERP integrations page covers how older and on-premise systems are reached.
How do you choose the right EDI alternative?
Count before you choose. Take a month of orders and sort them by sender: EDI, portal, and everything else. Then sort the everything-else pile by format. That split tells you which customers an option would cover and which it would leave on the desk.
A short decision path follows from the count:
- If most non-EDI orders come from a handful of large buyers, ask them about EDI or web EDI. Their volume can justify it.
- If most come from repeat buyers of standard items who are comfortable online, a B2B web shop will take a share of them.
- If they come from many customers, in many formats, with their own codes and descriptions, put an agent on the inbox. That is the group the other options leave behind.
Whatever you choose, keep EDI where it already works. An order that arrives structured does not need reading. The agent takes the rest, and the two run side by side into the same ERP. Our guide to order entry automation for wholesalers lists what to test before you buy.
Frequently asked questions
What is the best alternative to EDI for small customers?
For small customers who order by email, the best EDI alternative is one that asks nothing of them. An AI agent reads their emails, PDFs and spreadsheets, checks each line against your ERP and creates the sales order. Portals and web EDI move the typing to the customer, and many small customers simply decline to use them.
Is web EDI a good EDI alternative?
Web EDI works when a buyer is large enough to require it of its suppliers, or when a customer is willing to fill in your form. For a supplier trying to win orders from small customers, it moves the retyping from your desk to theirs. Customers who prefer email usually keep sending email, and the order lands back on your desk.
Does an EDI alternative replace our existing EDI connections?
No. Keep EDI for the accounts that already send it: a structured order needs no interpretation, and the connection you maintain keeps working. An AI agent handles the orders that arrive by email, PDF, spreadsheet or portal export, and creates them as sales orders in the same ERP, so both channels feed one order book.
Can we automate order entry into SAP without EDI?
Yes. Customers who will never send an IDoc can keep emailing their orders. An AI agent picks the order up from the shared inbox, matches the sold-to party and materials, checks price, quantity and delivery date against SAP, and creates the sales order. It works with SAP S/4HANA and SAP ECC, and exceptions go to your desk.
Will our customers notice anything?
Mostly, they notice faster confirmations. They keep ordering by email in their own format, with their own part numbers. At Topa Bathroom Products, some customers receive their order confirmation within 30 seconds of sending their email. Orders the agent cannot place go to your team, who can contact the customer as they always have.
Start with one inbox and a month of orders
The quickest way to judge an EDI alternative is on your own orders. Pull a sample from the shared inbox: the customer with their own article codes, the spreadsheet, the order that is only a description, the urgent change. Book a demo and we will run an agent against them, creating sales orders in your ERP with your rules, so you can see which share goes through on its own and which waits for your desk.
