Decoupled Sales Platforms
Your e-commerce team faces a daily paradox. On one hand, management demands more functionality: personalisation, loyalty programmes, new payment methods, marketplace integration. On the other, each addition slows down the site. Your e-commerce platform or online shop accumulates extensions, theme overrides, third-party scripts.
Loading time stretches out on mobile. Search ranking suffers for it, and every additional second of waiting makes visitors leave. Developers spend more time managing conflicts between modules than creating value.
Each update becomes a risk: an incompatible extension can bring down the checkout on a Friday evening. The marketing team waits for a release to modify a landing page because everything is locked in the back-office. Meanwhile, your competitors display their product pages with no wait. Technical debt accumulates, but completely rebuilding the platform means a long programme of work and a budget that no one will approve.
This solution belongs to the E-commerce & Booking family.
Challenges holding back your performance
Most optimisation attempts remain superficial. Image compression, aggressive caching, CDNs in front of a monolith: these patches gain a few hundred milliseconds but fail to address the structural problem. Your front-end remains captive to your back-end. When your e-commerce platform’s server struggles under the load of a traffic spike, the entire user experience collapses.Web agencies propose complete rebuilds on another e-commerce platform, but you then lose control of your business logic and ERP integrations built up over years. Some attempt PWAs, but without an architecture designed for resilience, the project drifts: you end up with a React front end as tightly coupled to your back end as the old PHP theme.
Our Technical Approach
Our approach consists of physically decoupling what your visitors see from what manages your orders. The front-end becomes an autonomous application, pre-generated and distributed across edge servers throughout the world. When a customer loads your page, it arrives from the point of presence nearest to them, not from an overloaded centralised server.
This front layer communicates with your existing e-commerce engine via APIs, but it does not depend on its availability to display a catalogue. If your e-commerce platform goes down, product pages remain accessible: only the ordering process switches to degraded mode. The marketing team can modify content, launch A/B tests, create landing pages without mobilising developers or risking breaking the checkout.
The developers, meanwhile, work on modern front-end code that is testable and deployable several times a day without maintenance windows. Search ranking rests on pre-generated pages: the measured display time falls, and your Core Web Vitals score can be read page by page.
Edge Rendering & CDN
Pre-generated pages served by servers closest to the user.
Orchestration of Tools
Strict decoupling enabling seamless integration of best-in-class software solutions.
Complete Resilience
If the payment engine fails, the catalogue remains perfectly navigable.
Headless Independence
Rapid design updates without risk of breaking order logic.
App-Like Experience
Instantaneous transitions between pages without heavy browser reloading.
Search Engine Optimisation
A structure built for indexing by search engines.

Smooth and frictionless integration
Your e-commerce platform, your online shop or proprietary system remains in place. It continues to manage the catalogue, pricing, stock, orders, ERP and logistics connections.
We build the front-end layer in parallel, section by section. We often begin with category and product pages: where the impact on performance is immediate. The checkout can remain on the legacy system whilst validating the approach. Your teams retain their usual administration tools.
No extensive training, no risky data migration.
Performance audit and mapping
Measurement of actual loading times, identification of bottlenecks, inventory of dependencies between existing front-end and back-end systems.
Architecture and prototype
Definition of the front stack, implementation of edge infrastructure, development of a pilot scope on part of the catalogue.
Progressive Migration
Section-by-section deployment with seamless traffic switching, validation of performance and conversion metrics at each stage.
Autonomy and continuous optimisation
Transfer of expertise to your teams, implementation of monitoring tools, documentation of deployment processes.
Measurable results for your organisation
- Category and product pages served from an edge cache, without waiting for the sales engine
- A buying journey that stays navigable when the back end slows down
- Core Web Vitals measured page by page on a pre-generated front end
- Traffic spikes absorbed without visible degradation of the catalogue
- Front-end changes deployed without a maintenance window
- Conflicts between extensions removed by decoupling the front end from the sales engine
Clarifying your decision-making
What is the impact on our current technical team? Do we need to recruit specialised profiles?
Your back-end developers continue to maintain the existing e-commerce engine. The decoupled front-end requires upskilling on modern frameworks, which Clarendis supports over the first months. Most teams then find this way of working more productive than maintaining a monolith.
What happens if our e-commerce back-end fails during a commercial operation?
Catalogue pages, product sheets and static content remain available from the edge cache. Basket and checkout switch to degraded mode with a waiting message, and everything resumes automatically when the back-end returns. Your customers see a slow site for a few minutes, not an error page.
