04 · Why nopCommerce
Unlike hosted SaaS platforms such as Shopify, this platform gives you direct access to the application source code, data and hosting environment. Built on ASP.NET Core, it supports extensive customization through themes, plugins and platform extension points.
For businesses that require full customization control — complex B2B pricing, multi-vendor marketplaces or industry-specific workflows — it can provide a flexible ecommerce foundation when its operational and licensing requirements fit the project.
The open-source edition uses the nopCommerce Public License 4.0 rather than the MIT License. Organizations can also evaluate a commercial license. Review the official licensing terms before distribution or white-label decisions.

06 · FAQ
The most common questions from teams evaluating the platform.
I work with nopCommerce 4.40 on .NET 5 through nopCommerce 4.90.8 on .NET 9. That includes maintaining older stores, upgrading across framework generations, adapting custom plugins and themes, and validating third-party compatibility before deployment.
nopCommerce is an ecommerce platform built on ASP.NET Core. Unlike hosted SaaS platforms such as Shopify, it gives teams direct access to the application source code, data, and hosting environment. It can be a stronger fit when a business needs complex custom functionality, B2B pricing rules, multi-store configurations, or direct infrastructure control, provided its licensing and operating model match the project.
Yes. I handle platform migrations to nopCommerce, including products, categories, customer accounts, order history, and SEO URL mapping. Whether you're migrating from WordPress, Magento, WooCommerce, Shopify, or a bespoke legacy system, I use backups, staged imports, record reconciliation, redirect mapping and rollback planning to reduce downtime and data risk.
Yes — custom nopCommerce plugin development is a core part of what I do. I design and build bespoke plugins for complex pricing engines, subscription billing, loyalty programs, ERP integrations, custom checkout flows, advanced shipping logic, and any workflow that the out-of-the-box platform doesn't cover.
nopCommerce can be a strong fit for B2B scenarios that require customer roles, tier pricing, restricted catalog access, multi-store management or custom purchasing workflows. The final fit depends on the quoting, approval, account hierarchy and integration requirements that must be implemented for the business.
Timelines depend on scope. A custom storefront commonly takes four to eight weeks after the design and page coverage are approved. Plugins, ERP integrations and migrations vary with business rules, data volume and testing requirements. I provide a scoped estimate after reviewing the target version, plugin list and acceptance criteria.
