Plinth handles the parts of SaaS billing that most founders put off until they break: failed payments, proration, bank transfers from enterprise customers, and the awkward emails when someone’s card declines.

Who it’s for

A SaaS company selling to Nigerian businesses. You have customers who pay monthly or annually, sometimes by card, often by bank transfer. You want revenue to flow automatically without building a billing engine from scratch.

What it does

Card billing

Tokenise a customer’s card once via Nomba. We charge it automatically on every renewal — no manual intervention.

Transfer matching

Every customer gets a dedicated virtual account number. When they send a bank transfer, we match it to their open invoice automatically.

Dunning & recovery

Smart retry schedule, configurable grace periods, payday-aware timing. Recovers revenue you’d otherwise write off.

What it doesn’t do

It’s not a payment processor. Plinth sits on top of Nomba’s payment rails — we orchestrate billing, not the underlying money movement. You still need a Nomba account for live payments.
