Every business faces unique technical hurdles. Webmerce provides the expertise to ensure your specific bottlenecks are permanently resolved.

Case Study 1: E-Commerce Architecture & Gateway Remediation

Client: High-Volume Multi-Channel Retailer

Service Category: UI Infrastructure & Checkout Optimization

  • The Challenge: The client experienced intermittent transaction timeouts and "ghost" cart abandonments during peak traffic hours. Initial audits revealed race conditions between legacy JavaScript template files and the primary payment gateway’s webhook listeners, causing approximately 12% of high-concurrency transactions to fail silently.

  • Technical Stack: Node.js, Stripe API, Redis (Session Store), Vanilla JS.

  • The Solution: Webmerce performed a root-level purge of legacy template scripts and implemented optimized server-side cart protocols. We re-engineered the checkout flow to prioritize session persistence via a Redis-backed store and hardened the payment gateway integration by implementing idempotent webhook handling. This ensured that even if a network interruption occurred, the transaction logic would resolve correctly without duplicating orders or dropping payments.

  • The Outcome: 

    •  Transaction Reliability: Successfully eliminated race condition failures, resulting in a 100% gateway verification success rate.

    • Performance: Reduced checkout latency by 450ms through script optimization and asset minification.

    • Integrity: Hardened infrastructure ensured zero downtime during subsequent seasonal sales events (Black Friday/Cyber Monday).

Case Study 2: Scalable API Logic & Operational Automation

Client: Specialized Logistics & Distribution Provider

Service Category: API Connectivity & Logic Automation

  • The Challenge: Manual data entry between the client’s ERP and fulfillment platform led to frequent shipping errors and inventory data corruption. Existing Zapier workflows lacked proper error-handling and retry logic, causing data silos to desynchronize whenever an API endpoint returned a 5xx error or non-standard JSON response.

  • Technical Stack: RESTful APIs, Zapier (Advanced Logic), JSON/XML Data Mapping, PostgreSQL.

  • The Solution: We engineered custom API middleware with robust data mapping. By treating automation as core infrastructure, we implemented advanced exponential backoff retry-logic and conditional filters. This system handles "edge cases"—such as partial inventory sync failures—by automatically logging the error and re-attempting the sync once the endpoint stabilizes, ensuring 100% data parity across the CRM and logistics providers.

  • The Outcome:

    • Accuracy: Eliminated 98% of manual data entry errors.

    • Operational Velocity: Reduced fulfillment lead times by 24 hours through real-time automated synchronization.

    • Stability: Built a modular automation layer capable of handling 10x current transaction volume without performance degradation.

What Sets Us Apart

Every business faces unique technical hurdles. Webmerce provides the expertise to ensure your specific bottlenecks are permanently resolved. Unlike traditional agencies that focus on visual design or surface-level patches, we differentiate ourselves through:

  • Root-Cause Remediation:

    We don't just fix symptoms; we identify and purge the "Technical Debt" and legacy dependencies that cause system instability in the first place.

  • Infrastructure Hardening:

    Our priority is building "Digital Safety Nets." We treat security and stability as core requirements, not optional add-ons, ensuring your environment is resilient against traffic spikes and platform regressions.4

  • Architectural Integrity:

    We provide the senior-level technical oversight found in Fortune 500 companies. Every automation and integration we build follows rigorous engineering standards, including idempotent logic and N+1 redundancy, to ensure long-term scalability.

  • Proactive Stewardship:

    We transition our partners from "reactive firefighting" to a state of proactive growth. By providing detailed roadmaps and continuity manuals, we empower leadership teams to make data-driven decisions based on a stable technical foundation.
