When Payments Systems Fail, Your Business Pays The Price
Every delayed payment, failed transaction, and complicated checkout process undermines your brand’s credibility. For businesses running on digital platforms, we take care of critical integrations with reliable, secure payment software directly impacting sales, revenue and customer experience.
Many businesses use outdated payment systems that cause transaction failures, security risks, and lost sales. Without a unified payment infrastructure, you face delays, missed opportunities, and cart abandonment, which can harm customer trust.
We integrate trusted payment gateways like Stripe, Square, and Authorize.Net into your website or app, creating a streamlined, secure, and efficient payment process. Whether it’s credit cards, digital wallets, or other methods, we simplify and secure the experience.
We start by assessing your current payment system, identifying issues like inefficient routing, security gaps, or slow transactions. Then, we customize the integration with Stripe’s SDK, Node.js for the backend, and React.js for the frontend, ensuring a smooth, user-friendly experience.
Example: A retail business integrates Stripe for global payments, allowing customers to pay in their local currency while staying PCI DSS compliant. This integration cuts cart abandonment by 25% and boosts payment success rates by 15%, driving revenue growth.
Payment systems lose revenue when transactions route through suboptimal processors. Static gateway configurations can’t adapt to regional approval rate fluctuations or card network performance changes, costing businesses 12-18% in unnecessary declines.
We implement dynamic routing engines that analyze real-time processor performance, card BIN patterns, and time-based trends. Using AWS Lambda for instant decisions, transactions automatically shift between primary (Stripe/Adyen) and regional acquirers (Rapyd in APAC, Nexi in EU) based on live success rates. Redis caches routing rules for sub-100ms response times.
Imagine an e-commerce site where transactions from customers in the APAC region are routed through a local processor like Rapyd, while transactions from the EU are directed to Nexi. This dynamic routing reduces declines by 20% during high-traffic periods, increasing transaction success rates and revenue.
Basic fraud tools often result in false declines and fail to catch advanced fraud, leading to financial losses. Merchants can lose up to 10x the fraud amount in chargebacks, fees, and lost revenue.
We use machine learning to analyze over 200 data points, such as device fingerprints and checkout patterns, to detect fraud in real time. Our system adjusts fraud detection thresholds based on transaction velocity, ensuring legitimate transactions go through smoothly while flagging potential fraud.
Our fraud protection integrates with Stripe Radar or Signifyd, automatically adjusting thresholds and sending alerts to your CRM via OAuth 2.0-secured APIs. This enables your team to act quickly and stop fraudulent transactions before they cause losses.
For example, imagine your subscription service detecting unusual checkout patterns in real time. Our system adjusts risk thresholds as transactions occur, allowing legitimate payments to go through while preventing fraud, significantly reducing chargebacks and protecting your revenue.
Storing raw card data in-house exposes you to security risks and complicates PCI compliance. We solve this by removing the need to store sensitive data altogether through P2PE encryption and tokenization.
By implementing Thales HSMs for key management, we ensure your security measures are top-notch. Our solution also automates the generation of SAQ-D reports using Terraform, reducing the time and effort it takes to maintain PCI DSS compliance. Tokenized payments flow seamlessly through trusted vaults like Braintree or Adyen, ensuring smooth, secure transactions for your customers while removing you from the compliance burden.
Example: A subscription service replaces sensitive card data with tokenized information, ensuring compliance with PCI DSS without the headache of raw card storage. Payments are securely processed through Braintree’s token vault, simplifying compliance and reducing security risks.
Failed recurring payments are a silent revenue killer. Outdated payment methods, expired cards, and manual recovery drain resources and hurt your bottom line. We handle all of that by automating your billing process.
We create event-driven systems using Kafka or PubSub, with smart retry logic optimized for your customers’ time zones. Our approach includes auto-update prompts for payment details (e.g., expired cards), and we integrate proration engines using Stripe Billing or Chargebee for accurate, flexible billing.
Example: A SaaS business automates subscription renewals with Stripe or Chargebee, triggering automatic prompts for customers to update payment details when cards expire. This keeps subscriptions active, reduces manual follow-ups, and boosts long-term customer retention.
Hidden FX fees and poor conversion rates hurt your international revenue. When customers see unexpected charges at checkout, they often abandon their cart. We solve this with dynamic currency conversion (DCC), giving customers a transparent, local price.
Our solution pulls real-time exchange rates from trusted providers like XE.com or CurrencyLayer. The system automatically routes payments through cost-effective processors while displaying prices in the customer’s local currency based on geo-IP detection.
Example: An online retailer automatically converts prices based on the customer’s location—customers in Europe see prices in EUR, while U.S. customers see USD. This prevents checkout surprises, reduces cart abandonment, and boosts conversions.
Reconciling payments can be a nightmare if you’re running both physical and online stores. Delays in payment processing between in-store and online sales can lead to inventory discrepancies and accounting errors. We integrate your POS systems directly with your e-commerce platform to streamline this process.
We unify systems like Clover and Toast POS with e-commerce platforms like Shopify or Square using a centralized transaction ID. This ensures real-time updates to inventory and financial records without the need for manual intervention.
Example: A retail chain synchronizes in-store purchases with the online system. Whether a customer buys in-store or online, the payment and inventory records update instantly, ensuring accurate stock levels and accounting without manual input.
Standard PCI compliance isn’t enough to protect your business from today’s evolving threats. We design multi-layered security systems that go beyond the basics, using HSMs for key management and quantum-resistant encryption protocols to secure your data.
Our architecture includes runtime application self-protection (RASP) to detect injection attacks and token vaults with format-preserving encryption. This ensures sensitive data like PANs is never exposed, even if a breach occurs.
Imagine a payment system where transaction data is encrypted consistently across all platforms. If a breach occurs, security layers automatically detect and stop injection attacks, ensuring that sensitive payment data, like PAN, is never exposed.
Off-the-shelf payment flows can be rigid and frustrating for customers, affecting your conversion rates. We create custom payment flows tailored to your unique business needs, ensuring a smooth and intuitive checkout experience.
Using React Payment Handlers for browser-based payments and native SDKs for mobile, we build adaptive flows that change based on payment method selection. Our designs prioritize customer experience by minimizing friction, offering one-click guest checkouts, and leveraging progressive disclosure to reduce abandonment.
Example: A customer selects a payment method, and the checkout process adjusts to request only the necessary details. This results in faster checkouts, reduced friction, and fewer abandoned carts.
Slow payment processing can directly impact your revenue. Every 100ms of latency decreases conversion rates by 1-2%. We find and eliminate bottlenecks in your payment stack to optimize performance and ensure lightning-fast transaction times.
We conduct a comprehensive performance audit of your payment systems, identifying delays from DNS lookups to gateway response times. Our solution includes Cloudflare Workers for edge computing, HTTP/3 QUIC protocol for faster data transfer, and predictive pre-authorization to start the transaction before the customer clicks.
Example: A customer hovers over the checkout button, and the system pre-authorizes the payment before they click. This reduces checkout delays and improves the overall speed of the transaction, increasing conversion rates.
Generic payment solutions can’t meet the needs of specialized businesses like subscription marketplaces or B2B platforms. We build custom payment systems using Golang for high-volume transactions and Rust for secure processing, offering flexibility that off-the-shelf solutions simply can’t.
Our custom solutions include dynamic settlement scheduling, multi-party escrow systems, and adaptive payment routing, allowing you to tailor the process to your unique business model.
Example: A marketplace customizes its payment engine to handle multi-party transactions, ensuring that funds are securely split between vendors without relying on generic solutions. This provides flexibility and reduces dependency on third-party systems.
For global businesses, failing to offer local currency options can lead to conversion drops of 15-20%. We implement true multi-currency processing, combining real-time data from 160+ central banks with local acquiring partnerships across 38 countries.
We optimize routing based on historical FX spreads, ensuring the best cost-effective path for each currency pair. Our system automatically displays prices in the customer’s local currency, improving conversion rates and reducing FX fees.
Example: An international retailer automatically converts prices to local currencies based on the customer’s location, ensuring the best settlement route. This reduces FX costs and boosts conversion rates by providing a transparent, localized checkout experience.
