In today’s digital economy, online sales are skyrocketing. Global e-commerce sales are projected to hit nearly $6.4 trillion by 2024, a 61% increase from 2020 (Statista, 2021). For merchants, having the right mix of online payment methods is crucial to capture this massive opportunity.
Offering a variety of convenient, secure payment options can help boost conversion rates, reduce cart abandonment, and ultimately drive more sales. In fact, the Baymard Institute found that 13% of consumers abandoned their carts due to limited payment options.
But with dozens of payment methods available globally - from credit cards and digital wallets to bank transfers and buy now, pay later - how do you choose the right ones for your business and customers?
This comprehensive guide breaks down the most popular online payment methods, their pros and cons, and key factors to consider as a merchant.
To make informed decisions about online payment methods, it's essential to understand the ins and outs of the most widely used options. Here's a detailed breakdown of four major payment categories: credit/debit cards, digital wallets, bank transfers, and buy now, pay later.
Credit and debit cards are the most common online purchase method, accounting for 51% of North American e-commerce transactions. With credit cards, customers can make purchases on credit and pay their card issuer later. Debit cards draw funds directly from the customer's bank account at the time of the transaction.
Advantages of accepting cards include:
However, there are also some drawbacks to consider:
Digital wallets allow customers to store their payment information and make purchases with a few clicks or taps. Major digital wallets include PayPal, Apple Pay, Google Pay, and Amazon Pay.
With in-app wallets like Apple Pay, customers can use biometric authentication (like Face ID or Touch ID) to securely complete a transaction without manually entering card details. This offers a fast and frictionless checkout experience.
PayPal, one of the pioneers of online payments, allows customers to pay straight from their PayPal balance or linked bank account/card.
The appeal of digital wallets for merchants and customers includes:
One potential downside is the added fees for merchants. PayPal, for instance, charges 3.49% + $0.49 per transaction. Merchants should compare fees and negotiate rates based on volume.
Online bank transfers and direct debit are viable options for customers who prefer to pay directly from their bank account. In the United States, the Automated Clearing House (ACH) network enables bank-to-bank transfers and direct payments.
With ACH payments, customers enter their bank account and routing numbers to initiate a transfer or give the merchant ongoing permission to debit their account for recurring charges.
The advantages of bank transfers include:
The main drawbacks are:
Buy now, pay later services like Affirm, Afterpay, and Klarna are rapidly gaining traction, especially among younger consumers. BNPL allows customers to split their purchases into installments, often with 0% interest.
For merchants, BNPL can be a powerful tool to:
However, merchants should weigh these benefits against the associated costs. BNPL providers charge merchants a 2-8% fee, significantly higher than card processing fees.
Another factor to consider is the financial health implications for customers. Critics argue that BNPL encourages overspending, which can lead to unmanageable debt. Merchants should clearly communicate terms to customers to promote responsible borrowing.
To optimize online payment acceptance, merchants must stay attuned to consumer preferences and market trends. Let's look closer at how payment method usage varies across geographies and demographics and how the COVID-19 pandemic has accelerated the shift towards electronic payments.
According to the Worldpay from FIS 2023 Global Payments Report, digital/mobile wallets are the most popular payment method worldwide, accounting for 49% of global e-commerce transaction volume in 2022. This is followed by credit cards (20%), debit cards (12%), and account-to-account transfers (9%).
Other factors influencing payment choices include:
The pandemic has accelerated the shift towards digital and contactless payments worldwide. A McKinsey study found that the share of digital transactions grew by 20-40% in select markets in 2020.
Contactless payments also surged, with 67% of merchants seeing an increase in contactless payment usage since January 2020 (Visa Back to Business Study).
The payment landscape is evolving rapidly, and there's no one-size-fits-all approach to online payment acceptance. Merchants must understand their specific customer base and market to determine the right payment mix.
This requires analyzing customer demographics, shopping behaviors, and preferred payment methods to identify gaps and opportunities in your current payment offerings.
It's also critical to stay on top of emerging payment trends and technologies, from digital wallets and QR codes to crypto and open banking, to future-proof your payment strategy. Partnering with a payment service provider that supports a wide range of local and alternative payment methods can help merchants adapt quickly to changing consumer demands.
Choosing the right mix can be complex, with numerous payment methods available, each with its own costs, benefits, and technical requirements. Here are seven key factors merchants should evaluate when selecting payment methods to support.
The most important consideration is aligning your payment options with customers' needs and preferences. Analyzing customer data and feedback can help you identify the payment methods that will drive the most conversions and satisfaction for your specific audience. For example, a merchant targeting Gen Z shoppers may prioritize mobile-friendly options like Apple Pay and buy now, pay later, while a B2B vendor may focus on bank transfers and invoicing.
Payment processing costs can significantly impact your bottom line. When evaluating payment methods, assess fees and negotiate rates with payment providers based on your transaction volume and average ticket size. Some providers offer bundled pricing or volume discounts that can reduce your effective rate.
Security is paramount in online payments. Data breaches and fraud can erode customer trust and result in costly fines and reputational damage.
When vetting payment providers and methods, look for providers that offer security compliance and fraud protection features, including PCI DSS compliance, tokenization and encryption, AVS and CVV verification, and chargeback prevention and dispute resolution services appropriate for your risk level and transaction volume.
Your chosen payment methods should integrate seamlessly with your existing tech stack, including your e-commerce platform, POS system, accounting software, and CRM.
Prioritize payment methods with pre-built plugins or APIs for your e-commerce platform to minimize development work and maximize customer conversion rates.
With consumers increasingly shopping across channels, supporting omnichannel payments is critical for a seamless customer experience. This means allowing customers to pay via their preferred method, whether they're shopping online, in-app, or in-store.
Choose payment providers that support your full range of sales channels and customer touchpoints, from mobile payments to online transactions. Some providers offer unified commerce solutions that consolidate online and offline payments into a single platform.
If you have a global customer base as part of your online business, offering locally relevant payment methods can be key to driving conversions and customer satisfaction in different markets.
This may include popular digital wallets like Alipay and WeChat Pay in China, bank transfer methods like iDEAL in the Netherlands or Sofort in Germany, or cash-based methods like Konbini in Japan or Oxxo in Mexico
Work with a payment provider with local acquiring capabilities and partnerships with local payment schemes in your target markets. They can help you navigate the complex regulatory and technical requirements of cross-border payments.
Continuously monitor and optimize your payment mix based on performance data. Key metrics to track include conversion rates and abandonment rates by payment method, average order value and customer lifetime value by payment method, chargeback and fraud rates, and cost per transaction and total payment processing costs.
Use this data to identify top-performing payment methods and areas for improvement. For example, if you see high abandonment rates for a particular method, you may need to streamline the checkout flow or offer alternative options.
Testing and iterating based on data-driven insights can help you fine-tune your payment strategy over time. Regularly solicit customer feedback as well to understand evolving preferences and pain points and build customer loyalty.
Online payments and digital currency are constantly evolving, with new technologies and innovations always emerging. Here are some of the most exciting developments shaping the future of payments and commerce.
Biometric authentication uses unique biological characteristics, such as fingerprints, facial recognition, or iris scans, to verify a user's identity. This technology offers a more secure and seamless alternative to traditional passwords or PINs.
As biometric technology becomes more advanced and cost-effective, we can expect wider adoption across various payment scenarios, from in-store POS systems to online and in-app checkout.
QR codes are two-dimensional barcodes scanned using a smartphone camera to initiate a payment. They offer a low-cost, contactless payment option that's particularly popular in developing markets where mobile payment adoption is high but card penetration is low.
Beyond in-store payments, QR codes can also be used for online checkout, bill payments, and peer-to-peer transfers. As more consumers become comfortable scanning QR codes, merchants may find them a valuable addition to their payment mix.
Cryptocurrencies like Bitcoin and Ethereum have emerged as a new asset class and payment method in recent years. While still volatile and not widely accepted, cryptocurrency offers some potential benefits for merchants, including lower transaction fees, faster settlement times, and increased security through blockchain technology.
The right mix of online payment methods is essential for merchants to thrive in today’s digital economy. As consumer preferences evolve and technology advances, offering various secure, convenient payment options can enhance the customer experience, boost conversion rates, and drive business growth.
