With an increase in the availability of e-commerce, millions of companies conduct e-commerce transactions every day. While payment processing might be second nature for more stable companies, high-risk merchants find the path from cart to checkout to settlement complicated. That’s why any high-risk merchant must understand what an e-commerce transaction is and how the payment flow process works. Once merchants are in the know, a high-risk merchant account provider can protect them from fraud, reduce chargeback rates, and ensure customers have seamless payment.
What Are Ecommerce Transactions?
E-commerce transactions are financial transactions processed over the internet for goods or services purchased online that rely on an online credit processor to make payments. This credit processor could be a credit card, debit card, ACH transfer, or even a mobile wallet, which is more popular today. In any case, after an e-commerce transaction takes place, a banking institution must authorize it, then the seller must get payment through a credit processor, followed by the official merchant making the sale to ensure all parties (and all fees) get paid. For regulated/high-risk industries, this adds another level of scrutiny as there are elements of some businesses that might allow for fraudulent (or non-fraudulent) activity, regulatory nuances, or increased chargeback risk. Understanding how e-commerce payments flow through the system can better prepare merchants to protect their revenue.
Where High Risk Differs
In many ways, high-risk ecommerce transactions are not different from ‘normal’ ecommerce transactions. However, it’s the players involved and what encourages or discourages certain behaviors that make the payment flow different. CBD-related companies, vitamin supplement merchants, firearms merchants (and many more), and the travel industries have much higher exposure to fraud and regulations that can make them more vulnerable to chargebacks[1]. Working with a high-risk merchant account provider is how these types of companies can get payment processing where other banking institutions or merchant service providers will not. Without such accounts, companies will have frozen funds, terminated accounts and an inability to accept payments at all. Therefore, working with a high-risk acquirer makes the process easier but also grants access to industry-specific tools that encourage fraud protection.
Why Payment Flow Matters for Ecommerce
Payment flow is the journey a payment takes from start to finish. In e-commerce, this includes authorization, authentication, transaction settlement and funding. For more heavily regulated industries, additional fraud screening, compliance and regulatory checks enter the equation to avoid exposure. But the more payment flow there is behind the scenes without customer interaction, the better the customer experience. Thus, merchants need to balance between ease of payment flow and security. Therefore, when payment flow does NOT go smoothly—transactions are declined, they’re overcharged, an unnecessary verification step appears, a regulatory check isn’t accurate—merchants risk a customer walking away from their cart and potential lost revenue. Yet when payment flow is prioritized, merchants can integrate with all necessary payment processing triggers that otherwise might be left out of the equation for fear of adding unnecessary customer friction.
How Merchants Make Their Own High Risk Merchant Account Provider
One of the biggest decisions a high-risk merchant can make for itself is to make its own high-risk merchant account provider. Not all understand what high risk means. The best merchants know what high risk means based on chargebacks, high chargeback ratios, multi-currency transactions and more[2]. The best merchants also have networks with banks that are likely to underwrite more high-risk merchant accounts with the caveat of compliance restrictions. So when a merchant partners with a high-risk merchant account provider, it can avoid the negatives of being flagged or marked as a high-risk merchant in other places[3].
How Merchants Secure Their Transactions
Transaction protection comes from the most secure platforms. Merchants in regulated spaces need PCI compliance protection, any and all security compliance protections to ensure no data is hacked or stolen after payment[4]. Merchant protection comes from chargeback alerts, dispute management programs and PCI DSS compliance support that gives merchants the opportunity to either save revenue left on the table from oversight or protect sensitive information from consumers who would otherwise have concerns.
