The headline number in Digital Commerce 360's reporting on business-to-business payments is structural, not promotional: ACH volume is growing as B2B ecommerce expands, and the bank-transfer rail is functioning as the quiet backbone of the channel rather than a legacy leftover.

That framing matters for distributors because payment method is a cost line, not a detail. Card interchange on a large industrial order can erode gross margin points that wholesale distributors work hard to defend. ACH pulls transaction cost toward flat, per-item fees, which is one reason finance teams at distribution firms have pushed buyers toward bank transfer even as the front end of the buying experience goes digital.

Digital Commerce 360's analysis positions ACH growth as a signal of broader digitization: as businesses move procurement online, they carry their preferred payment instruments with them. The check, long the default in wholesale channels, continues to cede share to electronic bank transfer. That shift compresses days-sales-outstanding, improves cash-flow visibility and cuts reconciliation labor — all measurable operating benefits for suppliers.

The catch, as with any payments story, is separating measured volume from asserted momentum. Digital Commerce 360 does not disclose specific transaction counts or dollar volumes in the item itself; the claim rests on the direction of ACH adoption within B2B ecommerce, a trend Nacha's published network data has supported in recent years. Readers evaluating their own payment mix should benchmark against their own channel: what share of orders now settles by ACH versus card, check or trade credit, and what that mix costs per transaction and per DSO day.

For distributors building ecommerce platforms, the implication is direct. A checkout that only supports cards imports retail-style interchange economics into wholesale margins. A checkout that supports ACH — including tokenized bank-account authorization so buyers do not re-enter credentials each order — protects margin at scale. The same logic applies to marketplaces and punchout integrations, where payment rails determine who controls the transaction and who captures the float.

The competitive dimension is also real. Where a distributor's platform makes ACH frictionless, buyers consolidate spend; where it forces card-only payment or manual bank transfer, buyers split orders across suppliers. Payment experience, in other words, is now part of channel power, alongside inventory depth, delivery speed and price transparency.

Digital Commerce 360 frames the trend as businesses "going digital" — a broad characterization, and one distributors should read as directional rather than quantified in the source item. What is asserted: ACH is growing with B2B ecommerce. What is not disclosed here: the rate of that growth, the verticals leading it, or the specific platforms benefiting. Those gaps define the analytical work suppliers must do on their own order data before reallocating payment investment.

The forward question is whether ACH's share gains hold as real-time payment schemes, embedded finance and buy-now-pay-later structures target B2B workflows. For now, the bank-transfer rail keeps compounding quietly underneath the digitizing wholesale channel, and distributors who instrument it — cost per transaction, settlement speed, share of digital orders — will see the margin effect in their own P&L before the market aggregates it into a headline number.
