eSellerHub: Built for eCommerce. Backed by TOPS
A dedicated division of TOPS Infosolutions, delivering modular backend systems for online sellers, 3PLs and multichannel retailers.
Commerce infrastructure, not just code
We’re a dedicated division of TOPS Infosolutions, with deep roots in engineering and commerce. Our purpose is simple: replace operational fragility with stability, so you can focus on growth, not firefighting.
We don’t believe in one‑size‑fits‑all software. Every business is unique so we build systems that adapt to how you operate, not force you to change.
We build pieces, or the full system
From inventory and order modules to warehouse, integration, and analytics, we deliver modular systems that integrate cleanly into your operations. You pick what you need; we build around you.
Key Capabilities:
- Custom Workflows & Logic Your business rules, embedded at the core.
- Market & Platform Integrations Shopify, Amazon UK, eBay, Etsy, Magento, ERP and accounting systems.
- Warehouse & Fulfilment Modules Receiving, picking, packing, routing, returns — built for UK/EU operations.
- Data & Reporting Real‑time dashboards, VAT‑ready exports, forecasting, alerts, and compliance metrics.
- Ongoing Engineering Support We don’t build and disappear — we stay with you through growth, change, and scale.
Built for longevity, not marketing
- You own your system: no recurring licensing fees, no revenue share, no lock‑ins.
- Delivered by a certified team of over 200 engineers with global project experience.
- Proven track record: trusted by hundreds of clients globally; UK‑oriented projects underway.
- Deep integrations: we handle the complexity (shipping carriers, VAT rules, marketplace APIs).
- Thoughtful architecture: systems evolve, don’t collapse under scale.
Built for Scale.
Engineered for Commerce.
We bring the engineering strength of TOPS Infosolutions with the focus of a dedicated division solving real problems in retail and logistics. Whether you need one module or a complete system rebuild, we’ll meet you where you are and deliver what you actually need.
Customization at Its Best
Every business works differently. Instead of forcing you to adapt to off-the-shelf software, we build around your workflows. No compromises.
No Recurring Fees
With custom software, you own it outright. No licence fees, no revenue share, no lock-ins. A one-time investment gives you full control and the freedom to scale.
Certified Developers
A team of 200+ certified engineers working in a professional infrastructure. We deliver projects on time with consistent quality.
Advanced Development Approach
DevOps and agile practices are embedded into our process. Continuous feedback loops mean your system evolves reliably.
Security Policies
Secure coding guidelines and protocols minimise risk: data protection, threat modelling, code reviews and more. Security is built in from day one.
Dedicated Support & Maintenance
We don’t walk away after launch. Our support team stays with you to troubleshoot, scale and optimise as your business grows.
Domain Expertise
Over a decade of hands-on experience across marketplaces, D2C and B2B operations. We understand what it takes to succeed in UK and EU commerce.
Our End-to-End Software Development Process
We follow a proven development lifecycle from discovery to launch, with post-deployment support designed to deliver stable, scalable, high-performance systems.
Requirement Analysis & Roadmap Planning
We begin with a detailed discussion to understand your operations, challenges, and long-term goals. From this we create a clear roadmap for development.
Project Wireframe & Prototype
Based on your requirements, we define the architecture and technology stack with scalability in mind. Wireframes, interactive prototypes, and workflows are produced for validation.
Core Module Development
With prototypes approved, we move into development. Modules are built to your specifications, with APIs and marketplace compliance handled in parallel.
Testing & Debugging
Each module is tested for integration, performance, and security. Unit testing and code reviews ensure reliability and alignment with marketplace and compliance requirements.
Software Deployment
After full testing, your system is deployed in a staging environment, then released into production with quality controls in place.
Post-launch Support
We will stay with you after the launch. From bug fixes and performance tuning to scalability and updates, our team ensures long-term stability and success.
