Scaling a B2B Payments App: What to Own and What to Abstract

Key takeaways:

• While product features, UX, and marketing scale efficiently like traditional SaaS, per-customer processes in B2B payments apps (such as compliance, banking relationships, and treasury operations) do not.
• As your B2B payments app grows, these operational burdens increase linearly or get worse with customer count, compounding against the business rather than for it.
• To scale successfully, platforms should focus on their core competitive advantages in-house (UX, brand, vertical expertise) while abstracting non-scaling infrastructure (KYB/KYC, compliance licensing, and banking/treasury networks) to a specialized third-party provider.

Scaling a B2B payments app, whether that’s in logistics, manufacturing, import/export, or another industry, requires a two-pronged approach.

The first, system-wide upgrades, scale like traditional SaaS. Meanwhile the second, per-customer processes, seem to only get more complex as you grow.

As you scale, it’s critical to know which parts of your growth are system-wide, which are per-customer, and when to abstract to a third party versus build in-house. The rest of the post walks through the split.

What scales in a B2B payments app

‍

The pieces of the business that follow software economics are ready to scale as your product grows:

• Product features and UX you build once and deliver to every customer.
• Brand, voice, positioning, marketing.
• Self-serve flows that absorb common customer needs without a human in the loop, such as AI-powered customer service or user patterns.
• Sales motion (once dialed in, marginal customer acquisition cost can decrease).
• Integrations into common customer systems built as configuration, not custom code per customer.
• Vertical depth and product expertise in your specific market.

These are where your competitive advantage lives. They're also where investment compounds — work spent here pays back across every customer you serve, and the marginal cost of serving the next customer in these dimensions stays low.

‍

What doesn't scale (and tries to look like it does)

‍

On the other side of the coin are the pieces that stay linear or get worse with customer count. These processes operate on a per-customer basis, including:

Compliance program operations including transaction monitoring, KYB, KYC, and other documentation needs depending on which countries your app operates in.

Operational challenges such as maintaining bank relationships in different countries and partner management across regions.

Regulatory compliance including Travel Rule tracking and jurisdiction-specific needs for business payments and reporting or record keeping.

Per-customer operations such as support escalation, dispute resolution, and customer-specific configuration.

Finance needs including treasury, reserve, and reconciliation operations across multiple customers. This will also likely include your audit and reporting infrastructure for both customer and owned books.

These look like things you could build once and run forever. In practice, every new customer adds load, every new regulation adds work, and every customer nuance becomes either a feature request or an escalation. They don't compound for your business; they compound against it.

‍

Why this matters more for B2B than B2C

‍

These challenges apply to both B2B and B2C (or remittance) use cases. Customer expectations make B2B more complicated.

In a B2B setting, customers expect more configurability than consumers do. They expect dedicated support, account management, and SLAs. They have multiple users with different roles and approval workflows. Their compliance requirements vary by their own industry and jurisdiction. Their integrations are bespoke.

The per-customer work that already doesn't scale gets more expensive when each customer is a higher-touch enterprise relationship.

‍

What to own vs. what to abstract

‍

The natural tendency is to own everything, because depending on a third party feels risky. The trap is that owning the parts that don't scale is what actually creates the risk. It caps the kind of business you can build.

What you can abstract: The structural move is to abstract the non-scaling parts to a provider whose specific job is operating them efficiently across many customers. The provider gets the economies of scale you can't get on your own because they can amortize their compliance program, banking relationships, regulatory monitoring, and KYB throughput across every operator they serve. You absorb their compliance program, licensing, banking relationships, multi-jurisdiction coverage, KYB throughput, and treasury infrastructure.

What you own instead: the things you'd never want to outsource. Your product, your UX, your brand, your customer relationships, your vertical depth. The parts that are your competitive advantage.

Where to go from here

‍

Audit your operation. For each function (compliance, KYB, customer ops, banking, treasury, reconciliation, audit, regulatory monitoring), ask honestly: is this scaling with our software, or is the cost growing linearly with our customer count? The functions in the second category are candidates for abstraction.

The provider conversation gets specific from there: which of those non-scaling functions does the provider actually absorb, and where do you still carry the burden.
