One-Stop Payment Rails for Vertical SaaS
Warren Brown, VP of Product at Order, on 4 ways to monetize payments in vertical SaaS
The strategic prize in embedded payments is shifting from best card API to control over the whole money movement stack. For customers like Order, the pain is not only processing fees, it is stitching together separate vendors for cards and ACH, then reconciling all that activity back to invoices, vendors, and cash balances. Lithic adding ACH moves it closer to becoming the default payments layer inside vertical software, not just the card engine behind it.

Order shows why multi rail matters in practice. It already uses cards for most vendor payments, about 80 percent of volume, but some higher ticket vendors only take ACH. A single provider that supports both means one integration, one set of webhooks, and one reconciliation workflow instead of separate payment ops for each rail.
-
Lithic itself frames ACH as an add on to card products, not a standalone business. That points to the real customer job, giving software companies a unified view of money movement, settlement data, and reconciliation while keeping cards as the core programmable rail for controls, authorization logic, and virtual card issuance.
-
This is a broader market pattern, not a one off. Earlier embedded finance stacks were modular, with one vendor for card issuing and another for ACH. Over time, platforms from Cross River to modern BaaS providers have pushed toward one stop coverage because startups want fewer counterparties, while larger customers still pick components rail by rail.
The next phase is likely a split market. Point solutions can still win where a customer needs deep control over one rail, but the biggest platforms in embedded payments will be the ones that make rail choice disappear inside software and turn cards, ACH, and newer money movement methods into one operational system.
