Outdated or disconnected inventory systems can cause stockouts, overstocking, and missed sales opportunities. Slow syncing between your store and backend results in inaccurate availability, overselling, and dissatisfied customers. 

Codewave develops cloud-based inventory and order management systems on AWS and Azure, utilizing an event-driven architecture and REST APIs for real-time stock updates. We use AWS Lambda for instant event processing, Azure Functions for automated workflows, and integrate directly with e-commerce backends, POS systems, and supplier feeds. This ensures complete visibility into stock levels and eliminates latency between purchase and inventory updates.

Example: Customers often purchase items that show as “in stock” online but are unavailable due to slow inventory updates. Real-time syncing will ensure that stock counts are updated instantly across all channels. This will prevent overselling, maintain accurate availability, and help gain customer trust.

Fragmented payment systems create friction at checkout, leading to cart abandonment. Slow transaction processing and weak security can erode customer trust and increase the risk of fraud. 

To combat these issues, we design secure, PCI–DSS–compliant payment workflows that integrate providers such as Stripe, PayPal, Razorpay, and cryptocurrency wallets into a single cloud-based infrastructure. Our approach combines tokenization (replacing sensitive card details with unique codes), real-time fraud detection engines like Stripe Radar, and end-to-end encryption to protect customer data from start to finish. 

Transactions are handled using REST APIs and webhooks for fast communication between payment providers and your e-commerce platform, ensuring each step is verified and processed without delay. This approach reduces checkout abandonment, strengthens customer trust, and increases the number of completed purchases.

Example: A customer wants to use both a discount code and split payment, but traditional systems struggle to process such transactions smoothly. With an optimized payment setup, transactions will be verified and completed across multiple gateways in under two seconds, preventing checkout frustration and leading to more successful purchases.

Traditional monolithic platforms tie the front end and back end together, making even minor updates require full system deployments. This slows innovation, limits experimentation with new features, and delays entry into emerging sales channels.

We develop API-first, composable headless commerce platforms using Magento Commerce (Adobe), BigCommerce, or commercetools. The architecture is powered by microservices that handle specific commerce functions, such as checkout, product search, or inventory, independently. These services run in containerized environments managed with Kubernetes, ensuring they can scale automatically during periods of peak traffic. 

Moreover, a global CDN and edge computing network distributes content and API responses closer to users, reducing latency and improving performance worldwide. This separation enables the front-end experience (web, mobile, kiosk, AR) to evolve independently of the core commerce engine.

Example: Adding an AR-based product visualizer currently requires changes across the entire platform, causing weeks of delay. With a headless setup, the AR feature will be deployed independently. This will cut launch time to days, avoid downtime, and keep the store adaptable for future innovations.

Manual or outdated billing systems make subscription management error-prone and slow, resulting in failed renewals and increased churn.

We design and implement subscription billing solutions using platforms like Chargebee, Recurly, or Stripe Billing, fully integrated with your e-commerce architecture through secure REST or GraphQL APIs. Our setups include automated invoicing workflows, smart payment retry logic, and event-driven triggers for key subscription lifecycle stages such as trial expiry, renewal, upgrade/downgrade. 

We configure webhook listeners to react instantly to payment events, ensuring that failed transactions are retried intelligently and customer accounts are updated in real-time. The system also supports multiple payment methods and tax calculation. 

This complete approach stabilizes recurring revenue, lowers churn rates, and ensures uninterrupted customer access to services.

Example: A subscription renewal fails because the primary card saved for payment has expired. The system will instantly detect the failure, trigger a retry with a secondary saved card, and send the customer a real-time notification with a secure payment link. This will recover the payment within minutes, prevent service disruption, and reduce involuntary churn.
