Discover how Fena's open banking ecommerce integration helps online merchants reduce fees, speed up payments, and deliver a seamless checkout experience — no card networks, no friction.

Open banking is quietly reshaping the way ecommerce works — and if you're still relying on card payments and traditional payment gateways as your default, you're leaving money, speed, and security on the table.

At Fena, we've built our payment infrastructure around open banking from day one. Not as an afterthought, not as a "future feature" — but as the core of how modern merchants should be getting paid. This post breaks down exactly what open banking integration means for ecommerce, and why it's a meaningful upgrade from the legacy payment methods most businesses still depend on.

What Is Open Banking Ecommerce Integration?

Open banking is a regulated framework that allows third-party providers — like Fena — to connect directly with a customer's bank account (with their explicit permission) to initiate payments, verify identity, or access financial data.

In an ecommerce context, this means your customers can pay directly from their bank account at checkout, without typing card numbers, without going through a card network, and without unnecessary intermediaries taking a cut.

The result? Faster payments, lower costs, and a checkout experience that actually makes sense in 2025.

Why Open Banking Is a Better Fit for Ecommerce

1. Direct Bank-to-Bank Payments — No Middlemen Required

Traditional card payments pass through multiple intermediaries before the money lands in your account. Open banking cuts straight through that chain.

With Fena, payments move directly from your customer's bank to yours — no card schemes, no third-party processors standing between you and your revenue. That translates into faster settlement and fewer points of failure.

2. Real-Time Payment Confirmation

One of the biggest friction points in ecommerce fulfilment is waiting on payment confirmation before you can ship, process, or activate an order.

Open banking solves this cleanly. Fena delivers real-time payment confirmation the moment a transaction is authorised, so your team can move fast, your fulfilment pipeline runs without delays, and your customers aren't left watching a spinner wondering if their order went through.

3. Built-In Security That Doesn't Rely on You

Card fraud is a persistent, expensive problem for online merchants. Open banking flips the security model entirely.

Instead of relying on merchants to protect card data, open banking requires customers to authenticate payments directly through their own bank — using biometrics, PINs, or two-factor authentication that their bank already manages. There's no card data transmitted, no payment details stored, and dramatically less surface area for fraud.

With Fena, that security layer is baked in from the start.

4. Lower Transaction Costs

Card payments come with interchange fees, scheme fees, and gateway fees. When you add them all up, the cost of accepting a standard card payment can range from 1.5% to well over 3% per transaction.

Open banking transactions via Fena carry significantly lower fees — and those savings compound quickly at volume. Some merchants pass that saving directly to customers as an incentive to pay via bank transfer; others simply protect their margins. Either way, you're not subsidising a card network with every sale you make.

5. A Checkout Experience Customers Actually Prefer

Long checkout forms are conversion killers. Every additional field a customer has to fill in is another opportunity to abandon the cart.

With Fena's open banking integration, the checkout flow is radically simplified. Customers select their bank, authenticate through their banking app, and the payment is done. No 16-digit card numbers. No expiry dates. No CVV codes. Just a clean, fast, frictionless handoff that keeps completion rates high.

6. Personalised Offers Backed by Real Financial Data

Open banking doesn't just move money — with the right permissions, it can also help you understand your customers better.

When customers consent to share financial data, merchants can use those insights to offer genuinely relevant promotions, payment plans, or product recommendations. Rather than guessing at customer intent from browsing data alone, you're working with a clearer picture of financial behaviour and purchasing patterns. Fena gives you the infrastructure to build those data-driven experiences compliantly and responsibly.

7. Financial Management Tools That Work Alongside Your Store

Open banking enables your ecommerce platform to do more than just accept payments. It opens the door to integrating budgeting tools, spending trackers, and financial dashboards that give customers real-time visibility into their finances as they shop.

That's not just a nice-to-have — it builds trust. Customers who feel in control of their spending are more likely to buy with confidence, return to your store, and engage with loyalty programmes.

Open Banking vs Traditional Payment Methods: The Core Differences

Rather than comparing line by line, here's the honest summary:

Traditional card payments

are familiar, widely accepted, and well understood — but they're also slow to settle, expensive to process, vulnerable to fraud at the data layer, and dependent on infrastructure built decades ago.

Open banking via Fena

is faster to settle, cheaper per transaction, more secure by design, simpler at checkout, and built to take advantage of how banking actually works today. The trade-off is adoption — open banking is newer, and not every customer will be familiar with it yet. But that gap is closing fast, and the merchants getting ahead of it now are the ones who'll benefit most.

Who Should Be Looking at Open Banking Ecommerce Integration?

Honestly? Most online merchants would benefit — but it's particularly compelling if you:

• Process high volumes of transactions and want to reduce the percentage you're losing to payment fees

• Sell higher-value goods where fraud risk and charge-backs are a concern

• Want to reduce checkout friction and lift conversion rates

• Are targeting customers in the UK, where open banking adoption is among the highest in the world

• Are building a fintech-adjacent product or want to offer embedded financial tools alongside your store

The businesses that make the switch to open banking now will spend less on transaction fees, process payments faster, reduce fraud exposure, and offer customers a checkout experience that's genuinely better than typing card details into a form.
