Choosing a new e-commerce platform is the exact moment when the future profitability of your business hangs in the balance. Too often, decision-makers rely on market hype and glossy vendor presentations. The invoice for these trend-driven choices arrives several quarters later, in the form of stalled deployments, runaway maintenance costs, and a complete loss of operational control.

Below are the key takeaways from the latest discussion on the myERP channel. Bogdan Jakubowski, Head of Technology at hmmh Poland, cuts through the noise, highlights the most common mistakes in tech stack selection, and explains how to build an architecture that actually pays back.

Watch the full interview below:

During our strategic workshops, we use the Arc42 framework to align stakeholders. We challenge decision-makers to select no more than three core architectural drivers.

Why is this constraint necessary?

If your immediate priority is infinite, rapid global scaling, microservices, and complex cloud environments are the right target. However, if your business requires rapid time-to-market, predictable budgets, and day-to-day stability, a modular monolith is often significantly cheaper to maintain.

The monolith has developed an unfair reputation in the IT industry as an outdated relic. In reality, it remains a highly secure, cost-effective environment that allows you to decouple and spin off specific modules only when your operations actually demand it and when your budget supports it.

Dependency on technology providers (vendor lock-in) is an operational risk that is rarely discussed during the sales pitch. When evaluating your system architecture, you must demand clear answers to three questions:

For example, a rich API allows you to seamlessly orchestrate orders and content using a headless CMS like Storyblok. On the other hand, closed SaaS environments offer rapid deployment but completely lock you out of diagnosing critical platform errors. Every option has its trade-offs; the key is choosing them consciously.

A significant portion of our clients come to hmmh Poland because their e-commerce implementation has completely stalled. They hand over architecture designed by a previous agency, only for our diagnostic audit to reveal a painful truth: while the structure might eventually work, the sheer cost of making basic development updates would devour the business’s entire profit margin.

When we step into these scenarios, we activate our Rescue protocol. We audit the bottlenecks, expose the operational risks, and lay down a realistic migration path to stable platforms like Shopify Plus or Shopware 6.

At the same time, we highly respect working with legacy code. If an older system is actively generating revenue, we design an evolutionary transition. We do not rewrite systems just to play with newer frameworks. Every single line of new code must justify itself on your P&L.

E-commerce technology is not a fixed administrative expense but an investment that must deliver a return. This is true whether you are a D2C brand scaling customer acquisition or a B2B manufacturer establishing a digital “Bridge to DACH”.

If your current setup produces unpredictable maintenance invoices while basic frontend changes take weeks of development, you are actively losing market share.

Book a technical audit of your e-commerce platform with our team. We will review your architecture and give you an honest, direct assessment of what needs to be stabilized, what can be saved, and what must be migrated.
