How a customer pays for something has always mattered. But in 2026, the payment options a Shopify store offers have become one of the most direct levers available for improving conversion rate and average order value, without changing a product, a price, or a single word of copy.

The data behind this is unusually clear. Offering accelerated payment methods rather than a checkout experience that lacks them can increase lower funnel conversion rates by upward of 50%, according to a BCG analysis of Shopify stores. Shop Pay specifically can increase lower funnel conversion by 5% through its presence alone. On mobile, the improvement is even greater at 91% compared to guest checkout.

These are not marginal improvements. For a store converting at 1.5%, a 10% relative improvement in conversion means 10% more revenue from the same traffic. For most merchants, that is the difference between a profitable ad campaign and one that breaks even.

This guide covers the payment options that have become meaningful in 2026, what the data shows about their impact on conversion and AOV, and the practical decisions Shopify merchants need to make.

Why Payment Options Affect Conversion More Than Most Merchants Realise

The default assumption is that a customer who reaches checkout has already decided to buy. The data contradicts this. Cart abandonment at checkout averages around 70% across ecommerce, and payment friction is a documented driver of that abandonment.

The mechanism is psychological. A customer who sees a checkout form asking for a 16-digit card number, expiry date, CVV, billing address, and shipping address is experiencing friction. A customer who sees a single "Pay with Shop Pay" button and taps once is not. The mental load is entirely different, and lower friction at a moment of financial commitment reduces the decision cost that causes abandonment.

The practical implication is that payment method choices are not just operational decisions. They are conversion rate decisions, and in 2026 the range of options available to Shopify merchants is broader than it has ever been.

Accelerated Checkout: The Highest-Impact Starting Point

Before evaluating any specific payment option, the highest-impact decision for most Shopify merchants is enabling accelerated checkout across the board.

Adding Apple Pay and Google Pay to mobile checkout increases mobile conversion by 10 to 15%, according to 2026 benchmarks. There is no cost to enable these options on Shopify Payments stores. They process at the same transaction rate as standard card payments. The conversion improvement is immediate and measurable.

Shop Pay now has over 150 million users worldwide, and customers check out four times faster than with traditional checkout. Its conversion advantage comes from stored payment and shipping details, which means returning customers face almost no friction at the payment step. For first-time buyers who are already Shop Pay users from other stores, that stored credential advantage transfers immediately.

The practical rule is simple: enable all available accelerated checkout options. There is no trade-off. They cost nothing to activate, they process at the same rate as standard payments, and the conversion data is consistently positive across store types.

Buy Now, Pay Later: The AOV Driver

Buy now, pay later has moved from a niche payment method to table stakes for competitive Shopify checkouts. 42% of US consumers use BNPL at least once per year, according to Statista's 2026 payment behaviour study. BNPL is projected to grow to nearly 7% of global ecommerce payment volume by 2027.

The core mechanic is straightforward. A customer sees a $200 product and hesitates at the price. When they see "4 payments of $50" displayed at the point of decision, the psychological barrier drops significantly. BNPL typically increases AOV by 20 to 50% because customers are making a smaller immediate commitment, which makes upgrading to a higher-value option or adding a complementary product feel less risky.

For Shopify merchants, the choice between BNPL providers is meaningful because the fees, approval rates, and customer bases are different enough to affect profitability.

Shop Pay Installments

Shop Pay Installments is Shopify's native BNPL option, available for US stores using Shopify Payments. It offers four interest-free payments for orders between $50 and $999, or monthly instalments with interest for orders up to $17,500. The merchant receives full payment upfront as Affirm, the underlying provider, bears the instalment risk.

The advantage is native integration with no additional app required. The limitation is geographic availability and the order value ceiling.

Dr. Squatch increased average order value by 60% with orders through Shop Pay Installments, which is an unusually large lift, but directionally consistent with broader BNPL data.

Klarna

Klarna is the most popular BNPL provider in Europe and growing rapidly in the US. It offers Pay in 4 (four interest-free instalments), Pay Later (full payment after 30 days), and Financing (monthly instalments for larger purchases).

Klarna's checkout widget displays the per-instalment price alongside the total, which makes higher-priced items feel more affordable at the point of decision. For merchants selling into European markets, Klarna has the brand recognition that reduces buyer hesitation in a way that US-native providers do not.

Afterpay

Afterpay (now part of Block/Square) offers four interest-free instalments and is particularly strong with millennial and Gen Z shoppers in the US, Australia, and the UK. Afterpay charges merchants a processing fee of approximately 4 to 6% plus $0.30, which is higher than standard card processing. For most merchants the conversion and AOV lift offsets this cost, but it needs to be measured specifically rather than assumed.

Benchmark data from 100-plus Shopify stores in Q4 2025 showed average AOV lift with BNPL of 12 to 18% and customer acquisition cost improvement of 8 to 12% across providers. Customers who use BNPL also show 18 to 22% higher repeat rates compared to those who use credit cards, which challenges the assumption that BNPL attracts lower-quality customers.

Which BNPL Provider to Choose

For most Shopify merchants, the answer is not one provider but a deliberate choice between them. The criteria are: geographic concentration of your customer base (Klarna for European focus, Afterpay for US/AU/UK millennial buyers, Shop Pay Installments for US stores already on Shopify Payments), average order value (BNPL is most impactful above $50, strongly impactful above $100), and margin structure (higher-fee BNPL providers need to be justified by the AOV lift on a store-specific basis).

Offering multiple payment options reduces checkout abandonment by up to 30%, which is the statistical case for evaluating more than one BNPL option rather than defaulting to whichever shows up first in a search.

Crypto and Web3 Payments: Real Demand, Niche Application

Crypto payment options have moved from novelty to a meaningful conversion driver for specific merchant categories in 2026. For stores selling to crypto-native audiences, tech products, gaming, or collectibles, offering crypto checkout removes a barrier that card-only checkout creates.

Shopify's integration with Coinbase Commerce and BitPay allows merchants to accept Bitcoin, Ethereum, and other major cryptocurrencies directly. Payments settle in fiat, so merchants are not exposed to crypto volatility unless they choose to hold.

For the majority of Shopify merchants, crypto payments are not a priority. For those whose customer base actively uses crypto, not offering it is a missed conversion opportunity with a low implementation cost.

International Payments: Currency and Local Methods

For merchants selling internationally, payment method strategy extends beyond BNPL and accelerated checkout into currency localisation and local payment method support.

Shopify Payments supports multi-currency checkout with automatic currency conversion, meaning customers see and pay in their local currency. The conversion impact of displaying prices in local currency rather than USD for international visitors is consistently positive, because currency uncertainty at checkout is a documented abandonment trigger.

Beyond currency, local payment methods matter in specific markets. iDEAL is the dominant online payment method in the Netherlands. Bancontact in Belgium. Sofort across Germany and Austria. For merchants with meaningful traffic from these markets, not offering the preferred local payment method is leaving conversion on the table regardless of product quality.

Shopify's payment provider ecosystem covers most major markets. The practical step is identifying your top five international markets by traffic and ensuring the preferred payment methods in those markets are available at your checkout.

The Practical Payment Audit

For merchants who want to act on this rather than just understand it, a practical payment audit covers four areas.

First: are all accelerated checkout options enabled? Shop Pay, Apple Pay, and Google Pay should be active on every Shopify Payments store. Dynamic checkout buttons should be displayed on product pages, not just in the cart. There is no cost to enabling these and the conversion data is consistent.

Second: does your AOV justify BNPL? If your average order value is above $50, BNPL is worth testing. If it is above $100, it is likely worth offering permanently. Calculate your current BNPL fee cost at your average transaction value and compare it to the AOV lift you would need to break even. For most stores above $75 AOV, the math works in favour of BNPL.

Third: are you tracking payment method conversion separately? Most Shopify analytics show overall checkout conversion but not conversion by payment method. Setting up tracking that shows which payment methods your customers are using, and what the conversion rate is for customers who see BNPL vs those who do not, is the foundation for optimising payment mix rather than guessing.

Fourth: for international merchants, are your top-five markets getting their preferred payment methods? Identify the markets that send your most traffic, check what payment methods are standard in those markets, and confirm you are offering them.

The Compounding Effect

Payment optimisation compounds with other conversion improvements rather than competing with them. A faster site with a better product page and an accelerated checkout converts better than a faster site with a better product page and a friction-heavy checkout. Each improvement multiplies the others.

The merchants who are winning on conversion in 2026 are treating payment as a product decision, not an administrative one. They are asking which payment options reduce friction for their specific customers at their specific price points, testing the answers, and measuring the results in revenue rather than assumptions.

For merchants who want to make sure that the orders those optimised checkouts generate arrive correctly, Tacey monitors every order from the moment it is placed, catching address errors, fraud signals, and fulfilment exceptions before they become problems that negate the conversion gains.
