How Alternative Payment Methods (APM) Works
Alternative payment methods follow a different authorization and settlement flow than card payments, but the end result—funds moving from buyer to merchant—is the same. The key difference is that each APM type has its own authentication mechanism, settlement timeline, and dispute process. Understanding the general flow helps merchants evaluate which APMs to integrate and how to handle edge cases like failed payments or refunds.
Customer Selects APM at Checkout
At the payment step, the customer sees a list of available payment options. Instead of entering card details, they choose their preferred APM—a digital wallet, bank transfer, BNPL plan, or local scheme. Presenting the right options for each market is critical to avoiding abandonment.
Redirect or Embedded Flow Initiates
Depending on the APM, the customer is either redirected to the provider's interface (e.g., a bank login page for iDEAL) or interacts with an embedded UI within the checkout (e.g., a PayPal button). The merchant's payment page hands off the transaction context to the APM provider.
Customer Authenticates and Authorizes
The customer completes the APM's authentication step—logging in, confirming a push payment, scanning a QR code, or selecting a BNPL repayment plan. For bank-based methods, Strong Customer Authentication (SCA) typically happens inside the bank's interface.
APM Provider Confirms Authorization
Once the customer completes their action, the APM provider sends an authorization or payment confirmation back to the merchant's payment infrastructure—usually via webhook or redirect with a status token. The merchant system validates this signal before fulfilling the order.
Settlement and Reconciliation
Funds settle according to the APM's schedule. Card-like wallets may settle within one to two business days. Bank transfers via account-to-account payments can be near-instant or take several days depending on the scheme. Merchants must account for these varying timelines in their cash flow and reconciliation processes.
Why Alternative Payment Methods (APM) Matters
The global payments landscape has shifted decisively away from card-only checkout. Merchants who treat cards as the default and APMs as an afterthought are leaving measurable revenue on the table in high-growth markets. The data is unambiguous: APM adoption is accelerating, and customer expectations around payment choice are rising.
According to the FIS Global Payments Report, digital wallets alone accounted for 49% of global ecommerce transaction value in 2023, making them the single largest payment category worldwide. Card payments, while still dominant in some Western markets, ranked second globally. A separate WorldPay analysis found that merchants who localized their checkout with relevant APMs saw up to 30% higher conversion rates in markets like Germany, Brazil, and Southeast Asia compared to card-only checkout pages.
The demographic picture compounds this trend. Younger consumers—particularly Gen Z shoppers in emerging markets—are more likely to have a mobile wallet or buy-now-pay-later account than a credit card. In markets like Indonesia or Nigeria, mobile money and local e-wallets are the primary financial instruments for hundreds of millions of people who have never held a traditional bank card. Reaching these customers requires APM support, not card optimization.
Market Penetration Benchmark
In the Netherlands, iDEAL accounts for over 60% of all online transactions. In Brazil, Boleto Bancário and PIX together represent the majority of ecommerce payments. A card-first checkout in these markets is effectively an exclusion mechanism.
Alternative Payment Methods (APM) vs. Card Payments
APMs and card payments are often framed as competing options, but they serve different customer segments, geographies, and use cases. Understanding the structural differences helps merchants make informed decisions about which methods to prioritize.
| Dimension | Card Payments | Alternative Payment Methods |
|---|---|---|
| Authorization model | Pull payment — merchant charges the card | Mix of push and pull depending on APM type |
| Chargeback exposure | High — card networks enforce chargeback rights | Lower for push-payment APMs (bank transfers, real-time schemes) |
| Global availability | Strong in North America, UK, Australia | Dominant in Europe, LATAM, APAC, Africa |
| Settlement speed | T+1 to T+2 typical | Ranges from instant (PIX, Faster Payments) to T+7 (some wallets) |
| Integration complexity | Standardized via card rails | Varies widely — each APM has its own API and flow |
| Recurring payment support | Strong, well-established | Limited for many APMs; tokenization support varies |
| Fraud liability | Governed by card network rules | Depends on APM type; push payments shift risk to payer |
| Customer trust | Familiar to card-holding demographics | Preferred or exclusive method in many markets |
For merchants operating across multiple geographies, the practical answer is to support both—cards for markets where they dominate, and the right local APMs for markets where they do not.
Types of Alternative Payment Methods (APM)
APM is a broad category. The specific methods a merchant should consider depend on their target markets, average order value, and customer profile. Understanding the major subcategories helps frame integration and prioritization decisions.
Digital wallets (PayPal, Apple Pay, Google Pay, Alipay, WeChat Pay) store payment credentials and enable one-click or biometric checkout. They are the fastest-growing APM category globally and reduce card-entry friction even in card-heavy markets.
Real-time bank payment schemes like iDEAL (Netherlands), PIX (Brazil), Faster Payments (UK), and SEPA Instant Credit Transfer enable direct bank-to-bank transfers that settle in seconds. These are push-payment methods with very low fraud exposure and growing merchant adoption. See local payment methods for market-specific scheme details.
Buy now pay later (BNPL) services like Klarna, Afterpay, and Affirm split purchases into installments. They increase average order value and conversion for higher-ticket purchases, with the BNPL provider absorbing credit risk. Full coverage in the buy-now-pay-later entry.
Prepaid vouchers and cash-based methods such as Boleto Bancário (Brazil), OXXO (Mexico), and Paysafecard serve customers who are unbanked, prefer cash equivalents, or distrust online payment entry. Conversion on these methods is lower due to offline steps, but they extend reach to otherwise unreachable segments.
Mobile carrier billing allows customers to charge purchases directly to their phone bill. Common in gaming, digital content, and markets with high mobile penetration but low banking access.
Open banking-powered payments use regulated API access to bank accounts to initiate transfers directly, often with lower fees than card processing. Strongly linked to open-banking infrastructure now expanding across Europe and beyond.
Best Practices
Implementing APMs effectively requires different thinking for merchants managing checkout strategy versus developers building and maintaining integrations.
For Merchants
Prioritize APMs based on data, not assumptions. Pull your orders by country and cross-reference with local market payment preference data. Start with the one or two methods that cover the largest share of your unaddressed customer base before expanding further.
Display APMs prominently at checkout. Burying a local payment option below a card form reduces its uptake dramatically. A/B test the ordering and visual weight of each payment method to find the optimal layout for each market.
Account for APM-specific settlement timelines in your operational workflow. A bank transfer scheme that settles in four days requires different order hold logic than a card authorization that clears in real time.
Maintain clear refund policies for each APM. Some methods, particularly voucher-based options, do not support automated refunds—you may need to issue store credit or initiate a manual bank transfer.
For Developers
Decouple your APM integration layer from your core checkout logic. Using a payment-orchestration abstraction means you can add, swap, or disable APMs without touching the core payment flow.
Implement robust webhook handling. Many APMs use asynchronous notifications rather than synchronous responses. Build idempotent webhook processors that handle duplicate delivery gracefully.
Test all APM flows in sandbox with deliberate failure scenarios: payment timeout, user cancellation mid-redirect, and webhook delivery failure. These failure paths are often under-tested and cause production incidents.
Standardize your payment status model. Map each APM's native status codes (pending, authorized, captured, failed, refunded) to a consistent internal enum so downstream systems behave predictably regardless of the payment method used.
Common Mistakes
Enabling APMs in all markets by default. Rolling out every APM globally without market-based filtering creates support overhead and confuses customers. A German shopper does not benefit from seeing Boleto Bancário in their checkout. Gate APM availability by IP, shipping country, or billing address.
Treating APM conversion the same as card conversion. Some APMs, particularly voucher and bank transfer methods, have inherently lower conversion because they require additional steps outside the checkout. Comparing APM conversion directly to card conversion without accounting for this creates misleading performance metrics.
Ignoring settlement mismatch risk. If you fulfill orders immediately but the APM settles in five days, you carry settlement risk on those orders. Define a fulfillment policy per APM type that matches your risk tolerance.
Skipping currency and locale alignment. APMs tied to specific markets often require that the transaction currency and locale match the scheme's requirements. Attempting to process iDEAL in USD, for example, will result in silent failures or degraded conversion.
Neglecting APM-specific compliance requirements. Some regional APMs come with local regulatory requirements around data residency, consumer protection disclosures, or KYC checks. Treat each new APM onboarding as a mini compliance review, not just a technical integration task.
Alternative Payment Methods (APM) and Tagada
Tagada is a payment orchestration platform, which makes it directly relevant to merchants managing multiple APM integrations. Rather than building and maintaining separate direct integrations for each method, merchants use Tagada to route transactions across a unified APM catalog through a single API.
APM Routing with Tagada
Tagada lets you define routing rules that select the optimal APM or processor for each transaction based on customer country, order value, currency, and real-time availability. If one APM provider is down or returning elevated failure rates, Tagada can automatically fall back to an alternative—keeping checkout conversion intact without manual intervention.
This is especially valuable for merchants expanding into new markets. Adding a new local payment method through Tagada means configuring a route and enabling the method—not scoping, building, and testing a new direct integration from scratch. For teams looking to scale APM coverage rapidly without proportional engineering investment, payment orchestration is the practical path forward.
