What we build

Custom commerce, from storefront to back office.

Storefronts, plugins, B2B workflows and integrations, built with nopCommerce and .NET to match how your business sells.

All services

Our products

Try our demo store, then browse what we sell.

We build and sell our own nopCommerce themes and plugins, the same way we build client work. Shop the live demo as a customer would, or see every product in our store.

Engineering expertise

Complex commerce challenges deserve custom engineering.

Standard storefronts handle standard businesses. When your pricing, workflows or system landscape are more involved, the platform needs to be engineered around them.

Pricing & catalog

Prices and products that follow your commercial rules.

Negotiated prices, tiered discounts and configurable products rarely fit a standard catalog. We model them inside nopCommerce so every customer sees the right product at the right price.

Built on nopCommerce customer roles, tier pricing and ACL, extended where your rules go further.

  • Customer-specific pricing

    Contract prices and price lists by customer, company or role.

  • Complex product catalogs

    Attribute matrices, configurable products and restricted assortments.

  • Bulk catalog tooling

    Import and maintenance tools for large or frequently changing catalogs.

Workflows & stores

Checkout and operations shaped around your process.

Approval routing, purchase orders, delivery rules and store-specific behaviour belong in the platform, not in email threads. We build the workflow once and let nopCommerce enforce it.

Custom steps are added through plugins and events, keeping the core checkout upgradeable.

  • Multi-store management

    Separate brands or regions with shared catalog and admin.

  • Role-based rules

    Behaviour that changes by customer group, store or order value.

Integrations

One source of truth across every connected system.

Stock, prices, customers and orders should move between nopCommerce and your back office without re-keying. We design integrations that are observable, retry safely and make data ownership explicit.

REST APIs, webhooks, scheduled tasks and message queues — chosen per data flow.

Why nopCommerce

Enterprise flexibility. Open‑source freedom.

nopCommerce is an open-source commerce platform built on ASP.NET Core. Its architecture makes it a strong foundation when a project needs deep customisation rather than configuration alone.

About the nopCommerce platform (opens in a new tab)

  • ASP.NET Core architecture

    Built on Microsoft’s cross-platform framework, with a familiar C# codebase and dependency injection throughout.

  • Plugin-based extensibility

    Payments, shipping, tax, widgets and integrations are added as plugins rather than edits to the core.

  • B2B customisation

    Customer roles, tier pricing and access control lists provide a solid base for trade commerce.

  • Multi-store support

    Run several storefronts from one installation, each with its own catalog, pricing and theme.

  • Multi-vendor capabilities

    Built-in vendor accounts give marketplace projects a starting point to extend from.

  • Integration flexibility

    Open source code and extension points let you connect external systems through plugins, APIs and scheduled tasks.

    B2B trade portal on nopCommerce, integrated with NetSuite

    Challenge
    A distributor’s retail-first nopCommerce store had no business accounts. Trade customers needed their own prices, team logins and on-account ordering, with NetSuite as the system of record.
    Solution
    A set of plugins on nopCommerce 4.80 adds company accounts with team roles, contract and level pricing from NetSuite, PO-based B2B checkout, live stock checks and order export to NetSuite as quotes.
    Results
    • Retail and guest checkout kept working unchanged alongside B2B
    • Orders reach NetSuite once, through an export queue with retries
    • Gated production releases with backup, maintenance page and smoke check

    Automatic monitoring and recovery for nopCommerce sites on IIS

    Challenge
    A business running many nopCommerce sites on several IIS servers found out about outages from customers. Stopped sites and app pools stayed down until someone noticed.
    Solution
    A .NET 10 Windows service checks every site each minute, applies one safe IIS recovery action after repeated failures, confirms the site is back and alerts the team in Microsoft Teams when it is not.
    Results
    • Version 1.0.1 shipped as an MSI installer with SHA-256 checksums and an SBOM
    • No changes needed to nopCommerce or the sites themselves
    • Built and released in about one week

    Three brand websites rebuilt on nopCommerce 4.80

    Challenge
    A distributor ran its brand websites on a mix of WooCommerce, WordPress and older nopCommerce versions, each maintained differently and some on .NET versions that no longer get updates.
    Solution
    Each site was rebuilt on nopCommerce 4.80 and .NET 9 with its own theme plugin, so the brand’s design and features live outside the nopCommerce source and the sites can be upgraded together.
    Results
    • Two sites moved from WooCommerce and WordPress to nopCommerce
    • One site rebuilt to match its existing design in four days
    • No edits to the nopCommerce source in any of the three

Questions

Frequently asked questions

Straight answers to what teams usually ask before starting a nopCommerce project.

Something else on your mind? Ask us directly.

What does custom eCommerce development include?

We design and build storefronts, business rules, ordering workflows and integrations to your requirements. Our specialization is nopCommerce and .NET, so the platform choice, extensions and delivery scope are discussed during discovery rather than assuming every business needs the same solution.

What types of nopCommerce customization do you provide?

We work across the platform: custom business logic, admin extensions, storefront themes, checkout changes, pricing rules, multi-store configuration and data model extensions. Where possible we implement changes as plugins rather than edits to the core, which keeps the store easier to upgrade.

Can you develop custom nopCommerce plugins?

Yes. We build payment, shipping, tax, widget, discount and integration plugins following nopCommerce conventions, and we can also update or extend existing plugins. You receive the source code along with installation and configuration notes.

Can you integrate nopCommerce with our ERP or CRM?

In most cases, yes — provided the system offers an API, database access or file-based exchange. We start by reviewing the system’s integration options and data ownership, then agree field mappings, sync direction and error handling before building.

Do you upgrade existing nopCommerce stores?

Yes. We assess your current version, plugins and customisations, recommend an upgrade path and flag anything that needs rework. Upgrades are rehearsed on a staging environment before the production cut-over.

Which nopCommerce versions do you work with?

We develop for and support nopCommerce 4.50 to 5.00, the current release. New projects start on 5.00 on .NET 10. If your store runs an older version, we can upgrade it first and then continue with the work you need.

Can you work with businesses internationally?

Yes. We are based in Dhaka, Bangladesh, and work remotely with clients in other countries. We agree communication channels, meeting times and delivery milestones at the start of each engagement so remote collaboration fits your project.

How do you estimate custom development projects?

Estimates are based on a discovery of your requirements and existing systems. For well-defined scope we provide a milestone-based estimate; for evolving work a dedicated-team model is usually a better fit. We explain assumptions and risks alongside every estimate.

Do you provide ongoing technical support?

Yes. Support engagements cover bug fixes, small enhancements, version and security updates, and performance reviews. Scope and response process are agreed in advance so you know what to expect.
