Business-Driven Software, Integrations & Automation
WebMagic is a custom software development and systems integration company headquartered in London, UK. We help e-commerce, logistics, and B2B teams streamline operations by turning business goals and workflow logic into production-ready web applications, integrations, and automation. Our work is business-driven: we begin with structured discovery to understand how your processes run in reality, where data breaks, and which steps create cost or operational risk. Based on this, we define clear requirements, success metrics, and a delivery plan with acceptance criteria—so scope stays aligned with ROI. A core focus of WebMagic is integration engineering. We build reliable connections between platforms such as Shopify, ERP/WMS/TMS systems, CRMs, payment providers, and carrier/shipping services. Typical projects include product and inventory synchronization, order and fulfillment workflows, shipping and returns automation, delivery exception management, and API integrations across internal tools and third-party systems. We design integration layers for resilience with validation, retries, idempotency, and monitoring to reduce manual intervention and keep reporting trustworthy. Where it creates measurable value, we implement AI-enabled automation for support workflows, knowledge retrieval when needed, request routing, and internal assistants—designed with clear boundaries, auditability, and safe fallbacks. Delivery is milestone-based with continuous QA, regular demos, and documented handover. We also provide DevOps and infrastructure support to ensure stable operations in production: cloud environments (AWS/DigitalOcean), containerized deployments (Docker/Kubernetes where appropriate), CI/CD pipelines, observability, security fundamentals, and performance optimization. After launch, we offer a 30-day stabilization period and ongoing support plans on a monthly or annual basis. If you need a partner to design, build, integrate, and operate software that improves logistics or e-commerce operations, WebMagic provides a practical, enterprise-oriented delivery approach.
