Alan HainingE-commerce platforms have traditionally been designed around a familiar pattern: a product catalogue, a basket, and a checkout.
For many organisations, that model remains effective. It is proven, widely supported, and quick to implement. However, as digital products and business models evolve, some organisations are finding that their requirements no longer align with the assumptions built into traditional ecommerce platforms.
This shift does not mean ecommerce technology is failing. It reflects how commerce itself is changing.
The shift away from standard e-commerce models
Commerce today often extends beyond the conventional online shop.
Examples include:
- B2B platforms with complex pricing, contracts, and permissions
- Digital marketplaces connecting multiple buyers and sellers
- Subscription and usage-based models
- Member-only and loyalty-driven experiences
- Commerce embedded in apps, services, or physical environments
- AI-assisted purchasing journeys
These models require flexibility across pricing, workflows, integrations, and user experience. Many traditional ecommerce platforms struggle to support this without compromise.
Why non-standard commerce was historically hard to build
Until recently, organisations building non-standard ecommerce experiences typically chose one of two approaches.
They either customised a traditional ecommerce platform beyond its intended use, or they built a largely bespoke system from scratch.
Both options came with challenges:
- Long delivery timelines and high implementation costs
- Complex custom code that was difficult to maintain
- Tight coupling between backend systems and user experience
- Limited ability to evolve once live
As a result, many businesses adjusted their operating model to fit the platform, rather than selecting technology that supported how they actually wanted to trade.
What has changed in e-commerce architecture
Recent developments are reducing these constraints.
Headless and composable commerce architectures separate core ecommerce logic from the customer experience. This enables teams to design experiences without being restricted by platform templates.
Managed infrastructure platforms are also reducing the operational burden of running scalable systems. Teams can focus more on product development and less on maintenance.
AI-assisted development is further shortening feedback loops and lowering the cost of experimentation. While it does not replace good architecture or experienced teams, it makes iterative delivery more accessible.
Together, these shifts have made flexible commerce architectures more practical for organisations of different sizes.
When platform limitations start to hurt growth
For growing businesses, platform constraints often become visible after launch rather than before.
Common signs include:
- Workarounds becoming permanent technical debt
- Feature requests blocked by platform assumptions
- Increasing reliance on brittle integrations
- Early discussions about replatforming
- Innovation slowing due to risk around core systems
At this stage, the issue is no longer speed to market. It is whether the platform can continue to support the business as it evolves.
Choosing flexibility without overengineering
Traditional e-commerce platforms still make sense when speed, simplicity, and standardisation are the priority.
However, when a business model is differentiated, evolving, or closely tied to digital strategy, flexibility becomes a strategic requirement.
In these cases, a modular commerce foundation can provide:
- Greater control over customer and user experience
- Lower long-term cost of change
- The ability to evolve without repeated replatforming
- A resilient base for future AI-driven use cases
The goal is balance. Flexibility should support the business without introducing unnecessary complexity.
Examples from Agilo’s Work
At Agilo, we work with organisations whose ecommerce requirements do not fit a traditional template. You can see how this plays out in real projects on our work page, including:
- Viessmann’s mission to digitise mobile heating rentals – a custom marketplace experience tailored to a complex business model.
- Tekla’s transformation with Medusa custom development – where bespoke solutions enabled features beyond a standard ec-ommerce platform.
- Operational improvements for Palmes Tennis Society – streamlining systems where a straight store model was insufficient.

Choosing an ecommerce platform is a long-term business decision. A useful question to ask early is simple:
Is the platform shaping the business, or is the business shaping the platform?
The answer often determines how sustainable growth will be.
