Seamless Shopping Cart Integration With Every Major Platform
Getting ecommerce payment processing up and running should not require weeks of developer time or a complete overhaul of your existing storefront. Our shopping cart integration approach is built around the platforms merchants actually use. Pre-built plugins for Shopify, WooCommerce, BigCommerce, Magento, OpenCart, Wix, Squarespace, and Ecwid mean you can connect your store to our payment gateway in minutes rather than days. Each plugin is maintained and updated regularly to stay compatible with the latest platform versions, so you never have to worry about a broken checkout after a routine update.
For merchants running custom-built storefronts or headless commerce architectures, our RESTful API and comprehensive developer documentation give your engineering team full control over the payment flow. You can embed payment forms directly into your site, build custom checkout experiences, and handle complex logic like split payments or marketplace disbursements. The API supports tokenization out of the box, which means sensitive card data never touches your servers — simplifying your PCI compliance obligations significantly.
Whether you are a small business launching your first Shopify store or an enterprise running a multi-brand Magento instance, the integration process is designed to meet you where you are. Our onboarding team walks you through configuration, tests transactions in sandbox mode, and ensures everything works before you go live.
Hosted Checkout Pages That Build Trust and Convert
Your checkout page is the most consequential moment in the customer journey. It is where buying intent either converts into revenue or dissolves into an abandoned cart. Our hosted checkout pages are designed with that reality in mind. They load in under two seconds, render cleanly on every screen size, and present a professional, distraction-free interface that keeps your customer focused on completing the purchase. You can customize colors, logos, and messaging to match your brand, so the transition from your storefront to checkout feels seamless rather than jarring.
Hosted checkout also solves one of the most complex challenges in ecommerce payment processing: PCI compliance. Because the payment form is served from our PCI-certified infrastructure, sensitive cardholder data never passes through your servers. This dramatically reduces your compliance scope, eliminates the need for annual on-site audits in most cases, and lets you focus on selling rather than security paperwork. Customers see a secure, familiar payment experience — complete with support for Apple Pay, Google Pay, and saved card details — which translates directly into higher completion rates.
For merchants who need even more control, our embedded checkout option lets you host the payment form directly within your site's DOM while still offloading card data handling to our secure iFrame. This hybrid approach gives you the design flexibility of a fully custom checkout with the compliance simplicity of a hosted solution.
"After switching to Paymetrics hosted checkout, our cart completion rate improved by 22% in the first month. The difference was immediate."

Checkout Optimization and Reducing Cart Abandonment
Industry data consistently shows that nearly 70% of online shopping carts are abandoned before checkout is complete. While some of that is casual browsing, a significant portion is caused by friction in the payment process itself — too many form fields, unexpected costs, slow load times, or a lack of preferred payment methods. Checkout optimization is not a one-time project; it is an ongoing discipline that directly impacts your bottom line. Our platform gives you the tools to identify where customers drop off and the features to address those pain points systematically.
One-click checkout for returning customers, auto-filled address fields, real-time shipping cost calculation, and support for digital wallets like Apple Pay and Google Pay all reduce the number of steps between intent and purchase. Our analytics dashboard shows you conversion rates at each stage of the funnel, so you can see exactly where abandonment happens and test changes to improve it. Even small improvements — shaving a second off load time, removing one unnecessary field — compound into meaningful revenue over thousands of transactions.
We also support abandoned cart recovery workflows that integrate with your email and SMS marketing tools. When a customer leaves items in their cart, you can trigger automated follow-up messages with a direct link back to their saved cart. Merchants who implement these workflows typically recover 5-15% of otherwise lost sales, making it one of the highest-ROI features available to online store owners.
Subscription and Recurring Billing for E-Commerce
The subscription economy has moved well beyond software and streaming services. E-commerce merchants across industries — from specialty coffee to pet supplies to beauty products — are building recurring revenue through subscription boxes, replenishment programs, and membership models. Our recurring billing engine is purpose-built for these use cases. You can define flexible billing cycles, offer trial periods, apply promotional pricing, and let customers manage their own subscriptions through a self-service portal that reduces your support burden.
Failed payments are the silent killer of subscription revenue. Credit cards expire, spending limits are reached, and bank-issued declines happen for reasons that have nothing to do with the customer's willingness to pay. Our intelligent retry logic automatically reattempts failed charges using optimized timing and updated card information from the card networks' account updater service. This alone recovers a meaningful percentage of otherwise lost recurring revenue each month, often without the customer ever being aware there was an issue.
For merchants selling physical goods on a subscription basis, the platform integrates billing events with your fulfillment workflow. Successful charges can trigger shipping label generation, inventory allocation, and customer notification — creating a fully automated cycle from payment to delivery. This kind of operational efficiency is what separates a subscription program that scales from one that drowns in manual work.
"Recurring billing through Paymetrics cut our involuntary churn nearly in half. The account updater and smart retry features pay for themselves many times over."

Online Fraud Prevention Without Sacrificing Good Orders
Fraud is a fact of life in ecommerce, but the way you manage it determines whether it is a manageable cost or a business-threatening problem. The challenge is not simply blocking bad transactions — it is blocking bad transactions without turning away legitimate customers in the process. Overly aggressive fraud filters can decline good orders, frustrate loyal buyers, and cost you more in lost sales than the fraud itself. Our online fraud prevention tools are built to strike the right balance, using layered screening rather than blunt rules to evaluate risk.
Every transaction is analyzed in real time against multiple signals: address verification (AVS), card verification value (CVV) matching, device fingerprinting, IP geolocation, and velocity checks that detect unusual purchasing patterns. These signals are weighted and combined to produce a risk score, and you control the thresholds that determine whether a transaction is approved, flagged for review, or declined. This means you can tune the system to match your business's actual risk profile rather than relying on generic settings that treat every merchant the same.
For merchants with higher chargeback exposure — digital goods sellers, international stores, or high-ticket retailers — we offer 3D Secure authentication (3DS2) as an additional verification layer. 3DS2 shifts fraud liability to the card issuer for authenticated transactions, providing a financial safety net even when fraud does slip through. Combined with our chargeback management tools, which help you respond to disputes with the right evidence in the right format, the overall effect is a fraud program that protects revenue from both sides of the equation.
Multi-Channel Selling and International E-Commerce Payments
Modern e-commerce is rarely confined to a single storefront. Merchants sell through their own website, through marketplaces like Amazon and Etsy, on social media platforms, and increasingly through in-person pop-up events and retail locations. Managing payments across all of these channels through separate providers creates reconciliation headaches, fragmented reporting, and inconsistent customer experiences. Our platform consolidates online store payments, marketplace payouts, and in-person transactions into a single merchant account with unified reporting, so you always have a clear picture of your total revenue regardless of where the sale originated.
International ecommerce introduces its own layer of complexity. Customers in different countries expect to pay in their local currency, use region-specific payment methods, and see pricing that accounts for local tax obligations. Our multi-currency processing supports over 130 currencies and automatically handles conversion at competitive exchange rates. Dynamic currency conversion gives international customers the option to pay in their home currency at checkout, which has been shown to increase conversion rates among cross-border shoppers by reducing price uncertainty.
We also support alternative payment methods that are dominant in specific markets — including iDEAL in the Netherlands, Bancontact in Belgium, and various local card networks across Latin America and Asia. For merchants serious about international growth, offering the right payment methods is not optional; it is the difference between a viable market and an inaccessible one. Our team can advise on which methods matter most for your target markets and help you enable them without adding operational complexity.
