Ecommerce Replatform Impact Model
Replatforming isn't just building a new website. It is disrupting your entire ecosystem.
Do you know what changes will impact your business, data, integrations, pricing and operations?
Critical questions to answer before an agency is briefed, not after.
Most replatforms cost more than planned. The reason is never the platform.
The ERP connector is almost always the last workstream budgeted and the first to run over.
Choosing a platform before defining requirements is the single most expensive mistake in digital commerce.
Sixteen components. Five dependency layers. One decision at the centre.
The Right Partners Replatform Impact Model maps every system in a typical UK ecommerce operation and shows exactly how it is affected when the platform changes. Some components break and must be rebuilt. Some survive and reconnect. Some — particularly the ERP connector and trade pricing rules — must be redesigned from scratch.
The model exists because most replatform projects fail not because of the platform decision itself, but because of what surrounds it. Dependencies that are invisible until they break.
If you are planning a replatform, this map should be reviewed before any agency brief is written.
Right Partners provides vendor-neutral replatforming advice for UK manufacturers and retailers. No agency agenda. No platform preference.
A reference guide to every system in your ecommerce stack and what happens to it during a platform change. Useful for briefing internal stakeholders and agency partners before a replatform begins.
Ecommerce platform
The platform is the centre of gravity for your entire digital commerce operation. Choosing it before your requirements are clear — or choosing the wrong one — sends a shockwave through the entire ecosystem. Every connection in this map either breaks, must be rebuilt or must be re-verified because of this one decision.
Storefront & UX
Platform-specific templating means your current theme cannot move to the new platform. Even preserving the same look and feel requires a full rebuild. This is an opportunity to improve UX and conversion — but it adds significant scope, cost and risk.
Product catalogue
Every product, variant, attribute, image and category must be mapped from the old platform schema to the new one. Different platforms handle product structures very differently. These structural differences create significant mapping complexity that is routinely underestimated.
Customer & order data
Order history, customer accounts and loyalty data must migrate carefully. Password hashing algorithms differ between platforms — customers frequently need to reset passwords post-migration. Historical order data may not map cleanly to the new schema.
The highest risk is never the platform itself. It is what surrounds it.
Most replatform conversations begin with platform selection. The answer matters. But it matters less than the dependencies around it — and organisations consistently discover this too late.
The ERP connector, trade pricing logic, product data migration and customer data migration are consistently the workstreams that run over budget, slip timelines and cause post-launch failures. They are also consistently the last to be scoped, budgeted and tested.
Before the agency brief. Before the platform demo.
Right Partners works with UK manufacturers and retailers at the point before a replatform begins. We define requirements, assess existing stack complexity, provide vendor-neutral platform guidance and identify the workstreams — like ERP integration and trade pricing — that will determine whether the project succeeds. We then stay accountable through delivery.

Ecommerce replatforming — common questions
The Right Partners Replatform Impact Model is a proprietary diagnostic framework that maps every system in a typical UK ecommerce operation and shows exactly how it is affected when the platform changes. It covers sixteen components across five dependency layers: platform, data, integrations, operational systems and marketing technology. The model identifies where risk concentrates, what must be rebuilt, what survives and what requires validation before go-live. It is available as an interactive tool at rightpartners.co.uk.
The Right Partners Replatform Impact Model™
Developed by Thomas Dee, Founder of Right Partners, based on two decades of ecommerce strategy and delivery experience across UK manufacturers, retailers and B2B distributors. The model reflects patterns observed repeatedly across replatform projects: the workstreams that consistently cause problems, the decisions that consistently get made too late, and the dependencies that are almost always invisible until they break.
Right Partners is an independent ecommerce consultancy. We have no platform preference and no agency agenda. Our advice is commercially grounded, vendor-neutral and tied to delivery.
