Launching a business account inside a SaaS platform

Vertical SaaS platforms — for clinics, contractors, salons, logistics firms — reach a point where the money their customers move is visible in the product but not handled by it. Offering a business account is the obvious next step, and it is a substantially larger undertaking than the demo suggests.

What you are actually building

Three things, which buyers often treat as one:

1. A regulated product — an account that can hold and move money, provided under someone's licence.
2. An onboarding process — every customer of yours becomes a verified business customer of a regulated firm, with all the diligence that implies.
3. A ledger and operations function — balances, reconciliation, disputes, support for money questions, which arrive in a different volume and tone from software support.

The licence decision comes first

Under your provider's licence you can launch in weeks; their appetite becomes your addressable market. With your own authorisation you control the product and carry the compliance function. Most platforms start under a provider's licence, and the ones who plan a migration path from day one are the ones who keep the option open. The BaaS selection guide covers this decision in full.

The stack, in procurement order

• Banking-as-a-service — accounts, IBANs, payment rails, the licence arrangement.
• KYC & KYB — verifying your business customers and their beneficial owners. Often bundled with the BaaS provider; check whose vendor sits behind it and what the pass rates are for your specific segment.
• Core banking & ledger — whose ledger holds the truth, and whether you can leave with it.
• Card issuing — usually phase two, but the choice of BaaS provider constrains it, so raise it in phase one.

What catches platforms out

Onboarding conversion. Your customers are used to signing up for software in two minutes. Business verification does not work that way, and the drop-off between "start account application" and "account open" is the number that decides whether this product works commercially. Ask every provider for straight-through rates on businesses like yours, not their average.

Support load. Money questions escalate faster than software questions and cannot be answered with a help-centre article. Staff for it before launch.

The sector question. Your customers' sector determines whether a provider will serve them at all. If your platform serves a category that sits outside most risk appetites, find that out in the first conversation rather than the fourth.

How to run the selection

Write requirements once, covering markets, customer profile, expected volumes, onboarding expectations, ledger ownership and exit — then put the same set to every provider. That is what the BaaS question bank is for, and it is what an RFP on Finlane collects in structured form so responses arrive comparable rather than each in their own shape.
