nopCommerce
Sandcastle is a Seattle web agency and nopCommerce Silver Partner. We build, upgrade, and maintain nopCommerce stores: custom themes and plugins, major version upgrades, B2B integrations, and hosting on Azure. If you run a nopCommerce store today, or you are deciding whether nopCommerce is the right platform, you are in the right place.
nopCommerce is an actively developed open-source e-commerce platform built on ASP.NET Core. It is free to use, you own your code and your data, and it handles serious catalogs, multi-store setups, and B2B requirements without per-transaction fees. It rewards good engineering, and that is what we do. Most of the store owners who call us are in one of three situations.
Southland Medical
Southland is a family-owned distributor of mortuary, medical, education, and forensic science supplies. We built their nopCommerce store and have supported it since 2019, including the built-in cXML punchout their institutional buyers order through.

Did your nopCommerce developer leave?
This is the most common call we get. The person or firm who built your store has moved on, and now you have a production site nobody understands. Orders are still coming in, but you are one plugin conflict or expired certificate away from a bad week.
We take over nopCommerce stores in exactly this state. The takeover starts with an audit: source code, database, customizations, third-party plugins, hosting, and SSL. We document what is custom versus stock, get the site into source control if it is not already, and set up a staging copy so nothing gets tested in production. From there you get ongoing maintenance and hosting on cloud infrastructure we manage on Azure, with a developer who actually answers.
How hard is a nopCommerce version upgrade?
Harder than the release notes suggest, and that is why upgrade work makes up so much of our nopCommerce practice. Minor updates are usually routine. Major jumps are not: nopCommerce rewrote its foundation moving from 3.x (ASP.NET MVC) to 4.x (ASP.NET Core), and each 4.x release since has changed plugin APIs and theme structure. Your theme and every custom or third-party plugin typically need rework, not just recompilation. Stores several versions behind cannot upgrade in one hop; the data has to be migrated up through intermediate versions.
Our upgrade process: inventory your customizations, price the rework honestly, migrate the database on a staging copy, port the theme and plugins, then regression-test checkout, tax, shipping, and payments before anything goes live. Staying current matters because old versions stop receiving security fixes and fall behind on payment and TLS requirements.
We also build what stock nopCommerce does not have: custom plugins, ERP and shipping integrations, and B2B features. That includes cXML PunchOut integrations we have delivered on nopCommerce, supporting Level 1 and Level 2 PunchOut plus cXML invoicing, so your store can plug directly into customers’ procurement systems like Ariba and Coupa. If you sell to hospitals, universities, or large enterprises that require PunchOut, read our deep dive on PunchOut for nopCommerce.
Is nopCommerce the right platform for your store?
Sometimes. We say that as a Silver Partner, because pushing the wrong platform creates unhappy clients. nopCommerce is a strong fit if you want open source without license fees, your team or host runs on the Microsoft stack, you need multi-store or B2B capability, or Shopify’s transaction economics and customization limits chafe. It is a weaker fit if nobody will ever touch code and you want a fully hosted SaaS.
We handle migrations in both directions: onto nopCommerce from platforms like Shopify or WooCommerce, and off nopCommerce when a client’s needs have changed. Products, customers, order history, and URL redirects come along either way. If you are comparing platforms, talk to us before you commit; our ecommerce services cover several platforms, so the recommendation is based on your requirements, not our inventory.

Can you take over a nopCommerce site another developer built?
Yes, this is one of our core services. We audit the code, database, plugins, and hosting, get everything into source control and a staging environment, then provide ongoing support and Azure hosting. You do not need documentation from the previous developer; we reconstruct what we need from the source and the database.
How long does a nopCommerce upgrade take?
It depends on how many versions behind you are and how customized the store is. The jump from 3.x to 4.x is a rebuild of themes and plugins on ASP.NET Core, while a single 4.x step is much smaller. We start with an inventory of your customizations and give you a fixed scope before any work begins.
Does nopCommerce support PunchOut for B2B customers?
Not out of the box, but we have built cXML PunchOut integrations on nopCommerce, including Level 1 and Level 2 PunchOut and cXML invoicing.

Can you migrate my store to or from nopCommerce?
Both directions. We migrate stores onto nopCommerce from platforms like Shopify and WooCommerce, and off nopCommerce when a different platform fits better. Migrations include products, customers, order history, and 301 redirects so you keep your search rankings.
Whether you need a takeover, an upgrade, or a platform recommendation, contact us and tell us where your store stands. A nopCommerce developer, not a salesperson, will get back to you.
