We help eCommerce companies move to a platform that meets their business goals today and supports further growth. Ecommerce replatforming makes it possible to simplify operational processes, improve performance, and create a technological foundation for scaling, entering new markets, and developing sales channels. We start each project by selecting the solution that best meets your business goals. We provide a full replatforming cycle: from analysis and design to development, migration, launch, and further improvement.
We combine strategy, architecture, development, integrations, and launch into a single process to make the transition to a new platform manageable, reduce business risks, and prepare the system for further development.
We study the current eCommerce system to determine the scope of changes, requirements for the new platform, and the appropriate transition scenario.
As part of the replatforming process, we help you choose a platform that meets your store requirements, budget, and business growth plans.
During replatforming, we redesign the architecture to create a reliable foundation for eCommerce development:
As part of eCommerce replatforming, we update the storefront in line with the capabilities of the new platform and customer expectations:
We unite key business systems into a single eCommerce environment:
We implement the new platform and transition the business to it as a new technological foundation:
We know how a platform can hold back business growth, so our replatforming approach helps you move to a solution that works with you, not against you.
Challenge
Risk
Solution
The business has outgrown the capabilities of the current platform.
The costs of support, improvements, and addressing technical limitations gradually increase.
We help you move to a platform that supports business growth rather than holding it back.
It is unclear whether the new platform will remain relevant in a few years.
Investments in replatforming do not pay off if the company quickly encounters the same limitations again.
We design the architecture with long-term goals and planned areas of development in mind.
The current system limits growth.
New features, integrations, and expansion into new markets are delayed while competitors move forward.
We develop a solution that accelerates the launch of new features, integrations, and areas of development.
The architecture no longer matches the scale of the company.
Every expansion of functionality turns into an expensive and risky project.
We establish a reliable technical foundation ready for increased load, integrations, and changes.
Technological limitations begin to determine the capabilities of the business.
The team gives up on new ideas not because of a lack of demand, but because of existing limitations.
We create an eCommerce platform that supports new products, sales channels, and business models.
From eCommerce to fintech, our clients span 20 countries and every project is different.
