Your biggest stockist places their next order without a human touching it. No rep call, no portal login, no purchase order buried in a 14-message email thread. Their agent checks sell-through, sees the gap, and buys.
This is possible now because two things landed close together. Shopify B2B went to all plans in Spring 2026, so wholesale catalogs, price lists, and payment terms stopped being a Plus-only build. And the Order and Catalog MCP endpoints let an outside agent read your catalog and place an order against it, with Flow able to charge a vaulted B2B payment method once the rules are met.
Concretely: your stockist's agent queries the catalog they're entitled to see, at the prices in their price list, with their minimums and case packs. It drafts the order against their reorder point. Flow validates it against credit terms, charges the vaulted card, and sends a confirmation to a human who mostly just reads it. On your side you aren't managing an order anymore. You're managing a catalog, a price list, and a set of rules that decide what an agent may do without asking.
The honest catch: agents reorder what already sells. They don't try your new flavor. Every rep visit that ended with "take 6 cases of the new one and I'll credit them back if they sit" disappears from the process. Machine reordering optimizes the existing mix and quietly kills discovery, so new SKU introduction has to live somewhere else. It will not survive contact with a reorder algorithm. Vaulted auto-charging also means a disputed order is now a disputed charge, so tighten your terms before you turn any of it on.
B2B on Shopify stopped being a moat in Spring 2026, the day everyone got it. What your catalog can tell a machine, and how fast it can say yes, is the version of the moat that's left.
