This fintech is quietly killing the diaspora payment tax

Nigerian merchants using fintech platforms have been losing up to 7% on every sale to their UK customers to Stripe, Visa, and Mastercard. That’s starting to change.

Before Nomba, Zaynab Odusote was running three separate financial lives.

Stripe for her UK customers. A different POS provider for her Lagos store. A separate bank account for local transfers. Every month, she stitched together a patchwork of platforms just to run one business, BeautyByDaz Nigeria, her Lagos-based beauty and skincare brand that sells in-store across Nigeria and online to diaspora buyers in the United Kingdom.

Then she joined Nomba in December 2025. 60 days later, she had processed 984 transactions across five payment channels, including POS card payments in Lagos, bank transfers in-store, NGN online collections, GBP collections from UK customers, and business banking, all from a single dashboard.

“My UK customers pay in pounds from their banking app, I see it instantly, and I can manage my entire business, Lagos and London, from one dashboard. It’s changed everything for me.”

Zaynab’s story is the clearest illustration yet of a quiet but significant shift in how African merchants are connecting to global payment infrastructure, and who is no longer getting a cut.

The fintech infrastructure reshaping diaspora commerce

This month, Nomba, which processes over ₦3 trillion monthly across 600,000+ Nigerian merchants, announced a partnership with Volume, a UK Open Banking payments platform, to let Nigerian businesses collect GBP directly from UK bank accounts.

The mechanics are simple. When a UK customer checks out on a Nomba-powered store, they select “Pay with Bank Transfer” and authenticate through their own banking app – Barclays, Monzo, HSBC, Lloyds, or any UK-regulated bank. The payment moves on domestic UK Faster Payments rails, is confirmed in real time, and settles into the merchant’s Nomba GBP account.

No card details. No card network. And no chargebacks. Bank transfers are irrevocable once authorised, eliminating a fraud risk Nigerian merchants have long had to absorb when selling abroad.

The fee difference is stark. Processing GBP via Stripe costs Nigerian merchants between 6.4% and 7.4% per transaction once you stack up the base processing fee, cross-border surcharge, currency conversion, and chargeback provision. Via Volume’s Open Banking rails, the effective cost drops to around 1%.

On Zaynab’s £5,522 in GBP collections over 60 days, that gap translates to £298 saved.

This is money that goes back into inventory and growth rather than disappearing into the payment chain. Annualised, it’s over £1,800 in recovered margin for one small merchant. For businesses operating at higher volumes, it scales into the tens of thousands.

The growth numbers are equally telling. Between December 2025 and January 2026, her GBP collections grew 92% month-on-month, from £1,391 to £3,238. Average order value climbed from £38.63 to £52.54 by early February, signalling repeat purchases and growing buyer confidence, not just new customer acquisition.

At her January run rate, she is on track for over £33,000 in annualised GBP volume from a standing start two months ago.

The United Kingdom is home to over 1.5 million people of Nigerian descent. The commerce they drive, spanning e-commerce, education payments, professional services, and subscriptions, has until now been routed almost entirely through card networks and legacy remittance infrastructure, both of which extract high cost at every step.

The Nomba x Volume integration is a direct challenge to that model. If Open Banking can replace cards for domestic UK commerce, there is no fundamental reason it cannot do the same across the UK-Nigeria corridor, provided someone builds the bridge. Nomba, with its regulatory licences spanning Nigeria, the US, and Canada, is positioning itself to be exactly that.

The immediate question for Nigerian merchants is practical: the integration is live now for WooCommerce, Shopify, and custom API setups. The larger question worth watching is whether GBP is just the beginning. EUR and USD corridors using the same Open Banking logic would open the model to African merchants serving diaspora communities well beyond the UK.

The story now is that a Lagos skincare founder is collecting pounds from Manchester through her customers’ banking apps, instantly, cheaply, and without Visa or Mastercard in the chain.
