Insights
Practical, implementation-level writing on nopCommerce upgrades, migrations, plugin development, ERP integrations and B2B commerce.
Each guide explains how a workflow is built, the decisions behind it and the limits of what the implementation proves. Examples use fictional products and sample records, never client data.
Upgrading to 4.90 or 5.0, what changes in 5.0, and moving a store to nopCommerce.
Upgrade guide
A practical nopCommerce upgrade procedure: choose 4.90 or 5.00, find your version path, keep the right App_Data files, let 4.40+ migrations upgrade the database, update plugins and themes, and test before go-live.
Release guide
Everything in the nopCommerce 5.00 release, from its source and GitHub milestone: .NET 10, price lists, reminders, AI SEO, forums and news as plugins, the removed Manual payment method, fixes made after the beta, and when to upgrade.
Upgrade guide
From the 5.00 source: the Misc.Forums, Misc.News and Misc.Polls plugins reuse your 4.90 tables and settings, but the upgrade doesn’t install them. Steps to bring content back, the menu links and theme calls that break, and why uninstalling deletes everything.
Upgrade guide
From the 4.90 and 5.00 source: what the Manual method stored, what 5.00 removes, why it matters for PCI, replacements for online, phone and recurring payments, SQL to clear old card data, and the third-party payment plugins that break too.
Upgrade guide
From the 4.70 and 5.00 upgrade code: old one-picture links left behind by 4.70 are copied again by 5.00. Who is affected, a read-only check query, a safe fix on 4.90, and how to remove duplicates if you have already upgraded.
Upgrade guide
From the 4.90 and 5.00 source: what order custom values are, the four new tokens by group, why the upgrade leaves the old token in your emails, queries to find affected and translated templates, and the drop-in replacement.
Migration guide
A practical plan for moving a store to nopCommerce 4.90: what the built-in import handles, the order to import data in, what to do about customer passwords, and how to map old URLs to 301 redirects before go-live.
Choosing and installing plugins and themes, payments, and building your own plugin.
Plugin guide
Start from what nopCommerce already includes, then add plugins for the gaps: a table by need, a checklist for judging a plugin, install steps, the three reasons a plugin won’t load, and when to build instead of buy.
Theme guide
Themes from the source code: the folder and theme.json, why a theme only needs the views it changes, a buying checklist, install steps, building your own from DefaultClean, the new plugin view overrides in 5.00, and why themes break silently at upgrades.
Developer guide
A working nopCommerce 5.00 widget plugin with settings and an admin page, written in the same patterns as the bundled plugins, plus the table of 4.90 to 5.00 changes we hit porting our own plugin: .NET 10, Mapster, moved namespaces and removed APIs.
Payments guide
From the source: the two bundled methods and everything PayPal Commerce covers, the three payment flow types, capture and refund support, a checklist for choosing a provider’s plugin, setup and testing steps, subscriptions, and why 5.00 dropped Manual card payments.
Platform guide
From the licence and the 5.00 source: why the link is required, what the removal key gives you, the hidden setting that turns it off and where to find it, why CSS hiding breaks the licence, and what to check in custom theme footers.
Hosting requirements, caching and the checks that keep a store fast and healthy.
Hosting guide
What nopCommerce 5.00 needs from a server, from its source code: ASP.NET Core Runtime 10.0.12, which kind of hosting fits, IIS and Linux setup steps, Docker, the exact folders to make writable, load balancing and the common startup errors.
Performance guide
From the 4.90 and 5.00 source: the default in-memory cache, the four distributed cache types and how synchronised memory works, a setup checklist and appsettings example, the SQL Server cache table, what else a web farm needs, and the usual real causes of a slow store.
SEO settings, product feeds and moving product data in and out of nopCommerce.
SEO guide
Twenty checks for a nopCommerce store, from the source code: which SEO settings are off after installation, how URL names redirect, what sitemap.xml and robots.txt contain, where structured data comes from, and the catalog gaps that hold product pages back.
Feed guide
Google replaced the Content API for Shopping with the Merchant API. Calls to the old API now fail more and more often until it shuts down in early 2027. How to check whether your store’s feed or plugin is affected, what changes in the new API, and how to move.
Feed guide
Product identifiers decide whether Google can match your product to the same item sold elsewhere. What GTIN, UPC, EAN, ISBN and MPN mean, which ones Google requires, where to find or buy them, and how to handle own-brand and handmade products.
Feed guide
Google sorts every product into its own category list, the product taxonomy. How the list is built, when Google needs you to set the category yourself, how product_type differs, and a practical way to map a whole store’s categories at once.
Feed guide
Microsoft Merchant Center puts products in Bing Shopping, Microsoft Shopping campaigns and Copilot. How to create a store, verify the website, bring products in by importing from Google or with a feed file, and fix the issues Microsoft reports.
Feed guide
nopCommerce has no built-in Google Shopping feed. How to choose between a feed plugin, a website crawl and a file upload, which nopCommerce field feeds each Google attribute, and how to fix missing GTINs, price mismatches and other disapprovals.
Catalog guide
When the built-in nopCommerce tools are enough, and how a free nopCommerce 4.80 and 4.90 plugin adds portable ZIP packages, SKU-based matching, preflight review and approved background imports — plus the limits to plan around.
Connecting nopCommerce to ERP systems and apps through APIs and plugins.
Integration guide
What a developer needs before connecting nopCommerce to an app or ERP: why “Web API Frontend” in Local plugins is only a placeholder, how the official API’s frontend and backend parts and JWT tokens work, the alternatives, and when a few custom endpoints are the better design.
Integration guide
How a custom nopCommerce 4.80 plugin divides work between scheduled NetSuite imports and outbound customer and quote exports, keeps quote export out of checkout, and where retries, acknowledgements and logging need workflow-specific testing.
What nopCommerce is, what it costs and how it compares with other platforms.
Platform guide
A plain overview of nopCommerce 5.00 for store owners: how the platform works, the 29 bundled plugins, what you pay for when the software is free, what the AGPL-based licence means, and when another platform is the better choice.
Comparison
A fair comparison from a nopCommerce agency: how hosted and self-hosted platforms differ, what each costs as sales grow, where nopCommerce leads on B2B, multi-store and vendors, and the stores that are better off on Shopify or WooCommerce.
If you are planning an ERP connection, plugin or B2B workflow on nopCommerce, we are happy to talk it through.
