The Checkout Button Wars Have Come for PayPal

You hit “Add to Cart”, scroll down, and suddenly there they are: a row of shiny payment buttons. Apple Pay. Google Pay. Shop Pay. And—tucked somewhere in the middle—the PayPal button. It used to be the king of express checkout, but things have changed. The checkout button wars have officially come for PayPal, and they're not going away.

I’ve worked on ecommerce optimization for over a decade, consulting for mid-market brands and Fortune 500s alike. I’ve seen PayPal’s dominance erode firsthand. Let me walk you through what’s happening, why it matters, and what you—whether you’re a merchant, a shopper, or an investor—need to know.

What Are Checkout Button Wars?

Think of the checkout page as a battlefield. Every brand with a digital wallet wants their button front and center. Apple wants you to use Apple Pay. Google pushes Google Pay. Shopify has Shop Pay. And PayPal? It wants to stay relevant. These are the “checkout button wars”. It’s a fight for real estate, convenience, and ultimately, the transaction itself.

The stakes are huge. The global digital payment market is expected to exceed $10 trillion in transaction volume. Every percentage point of share is billions of dollars in revenue. For PayPal, which once dominated the express checkout space, the threat is existential.

Why PayPal Is in the Crosshairs

PayPal’s core strength was its ubiquity. For years, it was the only universal checkout button accepted almost everywhere. But the rise of mobile wallets changed the game. Apple Pay is now on over 90% of iPhones in the US. Google Pay is baked into Android. Shop Pay offers accelerated checkout for Shopify stores (which power 10% of US ecommerce). Each of these players owns a distribution channel that PayPal can’t match.

Revenue data tells the story. PayPal’s total payment volume grew 13% in the most recent full year, but the overall market grew faster. Its share of digital wallet transactions in the US dropped from 45% in 2018 to about 30% today, according to industry estimates. Meanwhile, Apple Pay’s share has doubled.

And here’s the kicker: younger shoppers (Gen Z) don’t associate with PayPal the way millennials do. They prefer buying directly with credit cards or Apple Pay. I’ve seen A/B test results where replacing the PayPal button with Apple Pay increased conversion by 8% on mobile – a huge lift.

Competitors Calling the Shots

Let’s break down the main challengers.

Notice the pattern: each competitor has a captive ecosystem. PayPal, by contrast, is a standalone brand that relies on users remembering their password. That’s a liability.

Impact on Merchants and Conversion

If you run an online store, the checkout button wars affect your bottom line directly. I once helped a clothing brand restructure their checkout page. We moved PayPal from the primary position to secondary, and put Apple Pay as the default on mobile. Conversion jumped 6.2% over a month.

Why? Because fewer steps. Apple Pay requires just a thumbprint. PayPal opens a popup window, often requires login, and then redirects back. Each extra click loses you about 10% of users, according to Baymard Institute data.

Here’s my advice for merchants: Test your checkout flow today. Use tools like Google Optimize or VWO to compare a layout with PayPal vs. one without. You might be surprised. Many merchants keep PayPal out of loyalty or because they think it’s expected, but numbers don’t lie.

Checkout Friction Metrics

• Time to complete: PayPal adds 5–15 seconds vs. Apple Pay (1–2 seconds).
• Abandonment rate: Express checkout buttons reduce abandonment by 30–40%, but not all buttons are equal.
• Mobile vs. desktop: On mobile, PayPal’s drop-off is 20% higher than Apple Pay.

How PayPal Is Fighting Back

PayPal isn’t sitting idle. They’ve rolled out several initiatives to push back against the button wars.

• PayPal Checkout with Venmo: Integrating the Venmo brand to attract younger users. Venmo’s social feed is a unique asset.
• PayPal Pay Later (BNPL): Offering buy now, pay later options directly at checkout. This increases average order value and gives shoppers a reason to choose PayPal.
• Improved one-click checkout: The “PayPal Checkout” button now stores tokenized data for faster logins, but it still can’t match the zero-click Apple Pay experience.
• Partnering with large platforms: Inking deals with eBay (after years of separation), Magento, and BigCommerce to ensure PayPal remains a default option.

But these moves are defensive. The offensive strategy? PayPal is trying to become the operating system for small business payments with its PayPal Complete Payments platform. That shifts the battle from a button to a full payment stack. It’s too early to judge success.

What This Means for Investors

PayPal’s stock (PYPL) has been under pressure. From a peak of $310 in 2021 to around $70 today, the market is pricing in competitive threats. The checkout button wars are a key factor. As investors, you need to watch two metrics: active accounts growth and transactions per account. If both are flat or declining, PayPal is losing the checkout war.

On the other hand, PayPal still generates massive cash flow ($5B+ annually). They can acquire, innovate, or buy back shares. But the structural tailwind of ecommerce growth is now being shared by many. My view: PayPal will continue to be a major player, but its days as the undisputed king of checkout are over.

Investors should compare PayPal to competitors not just on revenue growth, but on checkout conversion data. A small shift in merchant preference can dramatically affect PayPal’s take rate.

Three Signals to Watch

1. Merchant surveys: If large merchants start removing PayPal as a primary button, trouble.
2. Apple Pay adoption: As Apple continues to expand into payments (e.g., Apple Card, BNPL), it will further squeeze PayPal.
3. Regulatory moves: Europe’s PSD2 and open banking could level the field, benefiting PayPal’s bank-agnostic model.
