Don’t adapt your business to a ready-made platform. Technology should align with your vision

Not every sales model can be supported by "off-the-shelf" solutions. We understand the specifics of complex business operations; therefore, we architect custom e-commerce systems fully tailored to individual needs and unique infrastructures.

Architecting and implementing scalable systems and custom e-commerce platforms

Who do we provide e-commerce development for?

B2B and B2C with non-standard sales processes

B2B and B2C with non-standard sales processes, complex configurators, or extensive product databases. Managing millions of SKUs? We are ready for the challenge.

Businesses that have outgrown SaaS platforms

Businesses that have outgrown SaaS platforms and are seeking flexible, scalable e-commerce systems – without licensing constraints or the risk of vendor lock-in.

Support for custom solutions and e-commerce integrations

Teams requiring support in building custom solutions – from architectural design to advanced e-commerce integrations with legacy ERP, PIM, WMS, and CRM systems.

Technology aligned with business growth

For you, if you are planning massive growth and know that technology must keep pace with your business, not hinder it.

Why build your e-commerce with us?

Discovery workshops and business analysis for e-commerce systems

Discovery workshops and business analysis for e-commerce systems

Every e-commerce replatforming or implementation begins with a Discovery workshop. Together, we analyze your business model, goals, and existing technical debt. As a result, we don’t just copy your current system; we re-architect it – simplifying dependencies and organizing data structures. Workshops are led by senior engineers with B2B project experience who will align the platform with your industry and scale.

Full customization and complex system integrations

Full customization and complex system integrations

We design custom e-commerce platforms strictly according to your processes – whether you need a dependency-based configurator, complex discount rules, or multi-level B2B customer structures. Every project includes all necessary e-commerce integrations: ERP, CRM, warehouse management, payment gateways, and any third-party APIs. We don't guess – we implement proven e-commerce engines operational in commercial projects across Europe.

Professional e-commerce development and rigorous testing

Professional e-commerce development and rigorous testing

The core of your project is executed by experienced developers and technical leads – we never delegate key tasks to juniors. Before any solution reaches production, it undergoes a full testing cycle: unit, functional, and integration tests. We verify not only the performance of a specific feature but also its impact on the entire architecture. We ensure full process transparency – no guesswork, no costly surprises.

Maintenance and total technological independence

Maintenance and total technological independence

The deployment of your system is not the end of our partnership. We offer ongoing support, new feature development, system expansion, and SLA coverage. If you decide to hand the project over to an in-house team or another firm in the future – it won't be an issue. We work with well-documented open-source technologies (Symfony/Sylius ecosystem). We deliver clean code and ensure complete freedom of choice.

PoC

Proof of Concept – rapid start and concept verification

We initiate projects with a PoC (Proof of Concept) – a functional prototype that allows for quick and cost-effective verification of business assumptions and technical approaches before further investment decisions are made.

Instant idea verification

Instant idea verification. Receive a functional system within weeks. Instead of theorizing, you test it with real data or present it to the board.

Fast decisions without guesswork

Fast decisions without guesswork. A real platform prototype speaks louder than the most polished PowerPoint presentation. A technical PoC drastically accelerates C-level decision-making processes.

Predictable costs for the PoC

Predictable costs. We operate on a Fixed Price model for prototypes – you know exactly what the execution will cost from day one.

PoC code ready for further development

Efficiency. Code written during the e-commerce PoC phase isn't a throwaway mockup. It serves as a solid foundation for the MVP e-commerce release, which we seamlessly evolve into a full-scale platform after testing.

Stages of e-commerce system design and implementation

Architectural workshop stage

Architectural workshop. We learn your goals, business logic, and technical requirements to co-develop an optimal system architecture concept.

Functional specification and estimation stage

E-commerce functional specification & estimation. Based on the workshop findings, we write a strict Functional Requirements Document (FRD). We define the scope for the PoC and provide a precise time and cost estimation.

Sprint-based development stage

Sprint-based development. We code the absolute technical essentials required to verify your concept. We provide regular demonstrations of functional components, allowing space for rapid testing and pivots.

I have known Commerce Weavers guys for many years now. They've always been a big inspiration for me because of their approach to programming and openness to the open-source community. No shadow of doubt they are the most experienced Sylius trainers. As their trainee - I can totally confirm they are splendid educators who make advanced topics easy and understandable. Finally, their business culture is simply top notch. If you decide to collaborate with them - you won't only get the work done at an excellent level but will also have a lot of fun.

FAQ – e-commerce implementation and migration

Yes. We begin development with a PoC. This is a small but functional system that allows you to quickly test key assumptions and minimize the risk of further investment decisions.

No. As system architects, we help you create it – starting with a Discovery workshop where we jointly define requirements, integrations, and deployment priorities.

The foundation of our solutions is a proven duo: PHP and the Symfony framework, with our specialty being high-performance implementations on the Sylius platform. We always select technology based on real business needs, creating systems that perform today and scale for the future.

Of course. We can work as an extension of your team, co-develop the system, or help your engineers take full responsibility after the collaboration ends.

We don’t have to implement the entire platform. We can focus on a specific area – such as a complex e-commerce integration with a legacy ERP, expanding cart logic, or severe performance optimization.

Timing depends strictly on the architectural scope. A PoC typically takes 8 weeks. We follow an agile approach and show results iteratively – you won't wait six months to see the first lines of working code.
