There is a version of B2B commerce that looks very clean in conference presentations. Integrated portals. Automated order flows. Suppliers and customers connected through APIs. Data moving frictionlessly from order to fulfilment, with humans reviewing exceptions rather than entering lines.
Then there is the version that exists in most operations teams right now. It is Tuesday at 9:15am. A long-standing customer has sent a purchase order as a PDF. A new distributor has sent their first order as a plain-text email with a product list pasted in the body. A supplier has sent a revised price list as an Excel attachment, two days before it takes effect.
None of this is going through a portal. None of it is triggering an automated flow. It is sitting in a shared inbox, waiting for someone to open it, read it, and manually do something with it.
Digital transformation has changed the tools on your desk. It hasn’t changed what arrives in your inbox.
The Gap Between the Promise and the Practice
B2B digital transformation has been a real story. EDI adoption grew. Procurement portals expanded. Large enterprise buyers increasingly require suppliers to integrate with their purchasing systems. E-commerce for business has genuinely grown, particularly for catalogue products where buyers know what they want and want to order it themselves.
But the story has a gap that often goes unacknowledged. The customers who were ordering by email in 2015 are still ordering by email in 2026. The suppliers who sent Excel price lists five years ago are still sending Excel price lists today. Not because they haven’t heard about digital transformation because email works for them, and switching their internal processes for one supplier relationship makes no sense.
The businesses that have embraced the transformation narrative most fully sometimes find themselves with sophisticated systems and processes on the supplier side, and an unchanged inbox reality on the customer-facing side. The portals exist. The customers just don’t use them.
Why Email Isn’t Going Away in B2B
It helps to understand why email has proven so durable in B2B operations, because it’s not a failure of effort or technology adoption. It’s a structural feature of how business relationships work.
B2B commerce runs on long-term relationships between specific people at specific companies. The customer who has been ordering from you for twelve years has a way of doing things. Their purchasing process involves their own internal systems, their own approval flows, their own document formats. The way they communicate with you is embedded in all of that. Asking them to log into your portal and re-enter their order is asking them to change their process for your convenience.
Most won’t. And the ones who will aren’t your most established, highest-value accounts, those tend to be exactly the customers with the most entrenched ways of doing things, the most complex orders, and the least incentive to change.
The customers who matter most to your business are often the ones most likely to keep ordering by email. That’s not a coincidence.
What This Means for Operations Teams
The practical consequence is a split-channel reality that most operations teams manage without ever quite naming it. There is the digital channel, structured, measurable, partially automated, and there is the inbox channel, which handles a significant share of order volume with entirely manual effort.
The inbox channel is where complexity lives. The large account that sends fifty-line orders in their own internal format. The international distributor who asks availability questions before every order. The supplier who sends price updates without warning, in a different format every time. These aren’t edge cases that will eventually migrate to the digital channel. They are the business.
Operations teams that have accepted this reality and built for it tend to be more resilient than teams waiting for the inbox to empty. The question isn’t how to get customers out of the inbox. It’s how to handle the inbox without everything depending on a person being there at the right moment.
The Change That Makes a Difference
For most of the last decade, the inbox channel was genuinely hard to address. Handling unstructured email at scale required either headcount or brittle rule-based systems that broke whenever a customer changed their format or a supplier updated their template.
What has changed is that AI has become genuinely useful at reading and understanding the kind of unstructured communication that fills B2B inboxes. Not in a futuristic sense but in a practical, operational sense. An agent that reads an incoming order, matches the customer’s product codes to your catalogue, extracts quantities and delivery requirements, and pushes a structured draft toward your ERP for review.
The teams beginning to use this aren’t replacing their people or their ERP. They’re addressing the specific layer where manual work concentrates: the handoff between what arrives in the inbox and what needs to be in the system. That layer has always existed. Now there’s something that can handle it.
And the agent learns. The first week, it handles the straightforward cases and flags the rest for review. Within a month, it has learned your customers’ ordering patterns which accounts always use their own article codes, which ones include non-standard delivery instructions, which supplier price lists always come in the same format. Within a few months, it’s handling the large majority of inbound volume without anyone needing to touch it, and your team’s attention is on the genuine exceptions.
The inbox isn’t going away. But the hours your team spends working through it don’t have to stay the same.
The Honest State of Things
Digital transformation in B2B is real and ongoing. But honesty about where it has and hasn’t reached is more useful than optimism about timelines that keep shifting. Most B2B operations teams will be handling email orders from important customers for the foreseeable future. The question is how.
The teams that have accepted the inbox as a permanent feature of operations and found a way to handle it reliably without routing everything through a person are the ones that scale without simply adding headcount. Their people work on what requires judgment. The routine volume gets handled.
Next week, we’ll look at exactly what happens when an AI agent takes over the inbound order flow step by step, from the email arriving to the ERP update, without the jargon.
