No, Your eCommerce Isn't Cannibalizing Phone Sales
What the data actually shows about digital vs. phone customers
The most common objection I hear from CFOs about B2B eCommerce investment:
“You’re just moving orders from the phone to the website. That’s not growth. That’s a channel shift.”
I used to struggle to answer this. Then I saw the data.
A note: I can’t name the companies below. But every number is real, shared directly by the people who ran these businesses.
The data that proved it wrong.
At a $2B+ food distributor, the eCommerce leader ran the full analysis. Segmented every customer. Controlled for region, category, buying habits.
The result: all of the company’s profits came from eCommerce customers. Not most. All.
If this was just channel shift—phone orders moving online—the profitability would be the same. It wasn’t.
The pattern repeats everywhere.
A $25B distributor analyzed over 100,000 accounts. Customers who adopted their B2B platform grew 20% faster than those who didn’t.
Same regions. Same categories. Same customer profiles. The only difference was digital adoption.
At a large electrical distributor, online customers spent 5% more on average. I used that stat constantly at Sonepar to justify digital investment.
At a distributor where I led digital, we saw the same thing. Online customers ordered more frequently and bought deeper into the catalog.
This isn’t channel shift. These customers are spending more money.
Why eCommerce creates sales the phone never could.
1. The phone doesn’t cross-sell.
Amazon let slip years ago that a third of their revenue came from recommendations. Customers came to buy one thing, left with 1.33x.
Your sales rep is focused on the urgent request. They’re not thinking “hey, you ordered industrial lubricant—need rags with that?”
The platform does. Automatically. On every order.
2. The phone has business hours.
When a customer can reorder at 11pm, they order more often. When they can check inventory without waiting for a callback, they don’t call your competitor instead.
Friction kills frequency. The phone is friction.
3. The phone doesn’t scale discovery.
Your rep knows maybe 200 SKUs well. Your catalog has 50,000. Every SKU your customer doesn’t know about is revenue you’re leaving on the table.
Search and browse behavior online exposes customers to products they’d never think to ask about on a call.
The real question isn’t “phone vs. online.”
It’s: what happens to customer behavior once they adopt digital?
They order more often. They buy more per order. They discover products they didn’t know you sold.
That’s not channel shift. That’s growth.
What to do Monday morning.
Run the analysis yourself:
Segment customers by digital adoption (online orders vs. phone only)
Compare order frequency, average order value, and margin
Control for company size, region, and category
Then show your CFO.
“eCommerce is just channel shift” is an assumption.
“Digital customers spend 20% more” is a budget conversation.
The companies that figured this out aren’t debating anymore.
They’re not asking “should we invest in eCommerce?”
They’re asking “how fast can we move our remaining offline customers online?”
Because every customer you convert becomes more profitable.
That’s not theory. That’s what the data shows.
