Although its main specialization is fintech rather than retail platform implementation, these capabilities can support ecommerce projects involving payments, customer accounts, financial workflows, or complex external services.
Its role in a BigCommerce project would most naturally involve software around the storefront, such as custom applications, payment-related integrations, administrative dashboards, APIs, and data exchange with other business systems. The project scope can cover theme design, platform configuration, and the technical work required to shape a consistent storefront experience.

BigCommerce API requirements, storefront frameworks, and third-party integrations should be defined clearly during the initial planning stage.

SoftPro is a Warsaw software development company working across responsive web applications, customer portals, cloud systems, modernization, and long-term technical support. Its technology practice includes React, Node.js, .NET, Azure, AWS, and modern frontend and backend architectures.
The company contributes to a BigCommerce project when the storefront needs a custom customer portal, external application, middleware layer, or integration with existing enterprise software. It is a more natural choice for technically demanding supporting work than for a straightforward store theme.
BigCommerce web design projects often involve far more than choosing a theme and changing a few visual elements. The right team should understand customer journeys, responsive design, product discovery, checkout behavior, integrations, performance, and the technical limits of the platform. Dedicated BigCommerce agencies are generally better suited to complete store builds and migrations, while broader design and engineering teams can help with custom interfaces, headless storefronts, external applications, and integration-heavy work. A clear project scope makes it easier to compare these options and select the most suitable delivery model.
