Custom nopCommerce Plugin Development

Plugins are the safest way to add capability to nopCommerce. We design and build custom plugins that encapsulate your requirements, follow platform conventions and can be maintained across versions.

Where this helps

Situations that typically lead businesses to this kind of work.

  • No marketplace plugin matches your requirements closely enough.
  • An existing third-party plugin needs changes but is hard to extend.
  • Custom features must survive future nopCommerce upgrades.
  • A provider you work with has no nopCommerce integration yet.

Capabilities

What we deliver

  • Payment plugins

    Integrations with payment providers, including redirect, hosted-field and webhook flows.

  • Shipping & tax plugins

    Rate calculation, carrier integrations and region-specific tax rules.

  • Widget plugins

    Storefront and admin widgets rendered into existing nopCommerce widget zones.

  • Discount & pricing rules

    Custom discount requirement rules and price calculation extensions.

  • Integration plugins

    Scheduled tasks and event consumers that synchronise data with external systems.

  • Plugin upgrades

    Porting existing plugins to newer nopCommerce and .NET versions.

Porting plugins to a new release? Read how SupportedVersions, .NET targets and plugin compatibility work in our nopCommerce 4.90 upgrade guide.

For an example of a custom integration plugin’s responsibilities — scheduled imports, background quote export, retry limits and logging — read how a nopCommerce plugin connects to NetSuite.

To see how a plugin can extend nopCommerce’s core product import and export with portable packages, preflight review and approval, read our Product Data Exchange plugin guide.

Building one in-house? Our plugin development tutorial walks through a complete nopCommerce 5.00 plugin and the changes from 4.90.

Before commissioning a plugin, check what’s built in vs what to add: nopCommerce 5.00 bundles 29 plugins, and the marketplace may already have what you need.

Approach

How we approach it

  1. 01

    Specify the behaviour

    We agree inputs, outputs, settings and edge cases before development starts.

  2. 02

    Build to conventions

    Plugins use nopCommerce interfaces, dependency injection and settings patterns.

  3. 03

    Package and document

    You receive the source, installation notes and configuration guidance.

Platform

nopCommerce versions we support

We build for and support nopCommerce 4.50 to 5.00. Each release runs on a specific .NET version, which sets the hosting a store needs and how much work an upgrade involves.

Stores on 4.40 or later upgrade the database automatically when the new release first starts. Plugins and the theme still need builds for the target version.
