Embedded Payments: How to Integrate Finance into Any Experience

The best payment isn't the fastest or the prettiest: it's the one the user never sees. If your customer has to stop to "pay," you've already lost part of the sale.


There's a confusion worth clearing up first. When people talk about "embedding finance," many picture BaaS—the license, the bank account, the card a brand issues under someone else's regulatory backing. That's embedded finance, and it's a separate topic. Here we're talking about something more surgical and far closer to conversion: the payment placed inside the user's experience, so that charging stops being a step and becomes part of the flow. Invisible checkout, payment inside a merchant's app, pay-by-link, wallets that remember the customer. Embedded payments are a subset of embedded finance, as Stripe explains in its comparison: embedded payments are payment capabilities integrated directly into software; embedded finance is the broad category that also includes lending, insurance, and investing.


The distinction isn't academic. BaaS gives you a license; embedded payments give you a conversion. And conversion lives or dies in the details of the flow.


Why the invisible payment is worth so much


The canonical example is Uber. You finish the ride, step out of the car, and the charge just happens, in the background, with no "pay now" screen and no re-keying your card. That was one of the first experiences to make payment truly invisible, as Payments Dive describes: the user loads their details once and, from then on, booking and paying are decoupled. They stop being two separate moments.


The contrast with traditional checkout is brutal once you look at the numbers. Cart abandonment averages 70.22%, per the aggregate of 50 studies from the Baymard Institute; and Baymard estimates that $260 billion in lost orders across the US and EU are recoverable through better checkout flow alone, with potential for up to a 35.26% lift in conversion rate. Every form field, every redirect, every "enter your card" is friction that costs money. Embedded payments attack exactly that: they remove steps until the payment nearly disappears.


One concrete figure from a vendor—labeled as such—sizes it up. Shopify reports that its Shop Pay wallet lifts conversion by up to 50% versus guest checkout, based on an external study done with a global consulting firm, according to Shopify itself. That's a vendor's number about its own product, so take it as that; but the direction matches Baymard's neutral data: less friction, more sales.


How this is enabled: by API, not manual integration


Here's the point almost no one connects. An invisible payment isn't front-end magic. It's orchestration: tokenizing and storing the payment method, authorizing against the processor, reconciling, handling retries, refunds, chargebacks, and merchant settlement. All of that has to be triggerable from the merchant's software with a single call, in real time, responding in milliseconds.


That only works if the payment platform and the core expose those operations via API. If your billing system only speaks in nightly batches, there's no way to build a payment that happens "by itself" at the exact moment the user completes their action. The difference between a checkout that converts and one that's abandoned often isn't in the button design: it's whether the core can confirm the payment online or sends the user off to wait.


The opportunity—and why the core matters


The market confirms it. Bain & Company calculates that embedded finance grew from $2.6 trillion in US transactions in 2021 to a projected $7 trillion-plus by 2026; and within that total, consumer payments alone moved $1.7 trillion in 2021 with a projection to $3.5 trillion, making payments the largest segment of the whole category. In Europe, McKinsey projects embedded-finance revenues could surpass €100 billion by 2030, between 10 and 15% of banking revenues. Embedded payments aren't a UX fad: they're where the volume is moving.


LATAM: the ground is more ready than it looks


The region has a peculiar edge: instant-payment rails already normalized real-time charging. In Brazil, Pix moved BRL 28 trillion through October 2025 alone, with 170 million adults and more than 20 million companies using it, according to Agência Brasil with Central Bank data. An instant, API-driven rail is exactly the raw material of an embedded payment: immediate confirmation, no card, inside the flow.


And the region's platforms already exploit it. Mercado Libre, via its credit arm Mercado Crédito, extended more than $3.3 billion in loans in 2023, integrated into the buying experience of its own marketplace, as coverage of its embedded-finance strategy reported. Payment—and financing—live inside the product, not in a separate tab.


How we see it at WAU


At WAU we don't sell you a pay button: we design the core that makes the payment disappear. That means a platform that exposes authorization, tokenization, reconciliation, and settlement via API, in real time, governed and traceable, so that any experience—your app, a partner merchant's, a pay-by-link, a wallet—can charge without pulling the user out of the flow. Embedded finance is the license; embedded payments are the conversion. And conversion is defined by your architecture: a core that confirms online converts; one that answers in batches gets abandoned.


If you want charging to stop being a step in your product and become an invisible part of the experience, let's talk. We'll help you see what your core needs to enable real embedded payments. 👉 Book a conversation with our team.
