What an Umbraco developer actually does
When brands look for an Umbraco developer, they are typically searching for a specialist who can build or maintain a solution on Umbraco. It is an open source platform built on Microsoft's .NET, so the work demands solid experience with C#, backend development, setting up content structures and integrating with business systems such as ERP and CRM.
Umbraco is first and foremost a content management system, a tool for editors to manage the content on a website. It is flexible and gives you full control, but it is not an e-commerce platform in itself. If you want to sell online on Umbraco, it requires either an add-on module or dedicated custom development on top of the platform. That is an important distinction, because many people confuse a strong CMS with a strong commerce platform.
The pitfalls of a custom-built Umbraco webshop
An Umbraco solution is powerful, but it ties your business closely to the individual developer or the agency that built it. When the shop itself is custom-developed, the logic for cart, checkout, payment, inventory and discounts lives in code that only a few people understand. That leaves you vulnerable, and it makes every change more expensive than it needs to be.
Maintenance is the second pitfall. A custom-built webshop requires ongoing updates, security patches and hosting, and you pay for developer hours every time a payment provider changes its API or a new feature needs to be added. At Mercive we see many brands that, over time, spend a large part of their budget simply keeping the lights on instead of growing sales.
The third point is speed to market. Where a modern commerce platform delivers checkout, payment and apps out of the box, an Umbraco webshop often has to build all of it from scratch. That significantly extends time to market and shifts focus from business to infrastructure.
When an Umbraco developer is the right choice
There are good reasons to hire an Umbraco developer. If your primary need is a content-heavy website with complex editorial requirements, deep integration with internal .NET systems or very specific demands that no standard platform covers, then Umbraco makes sense. In those cases a freelance Umbraco developer can be a cost-effective route, because you get the expertise directly without an agency as a middleman.
But for brands where sales are the core of the business, the calculation is often different. When most of your solution is about selling, converting and scaling, it is worth asking whether the CMS approach genuinely supports that growth, or whether it locks up capital in technology that should be standard.
Mercive's perspective: from Umbraco to Shopify Plus
Mercive is a Shopify Plus agency, and our experience is clear. For most growth-oriented brands, a dedicated commerce platform is a better investment than a custom-built CMS webshop. Shopify Plus delivers checkout, payment, security, hosting and a large ecosystem of apps as standard, so your developer budget goes toward conversion improvements instead of basic infrastructure.
When we move a brand off an Umbraco solution, we start by mapping data and business logic so nothing is lost. Products, customers, order history and URL structure need to be migrated correctly, and integrations with ERP and CRM must be rebuilt in a way that stays maintainable going forward. Our work with custom platform migration is precisely about making that switch safe, with no loss of SEO or revenue.
In practice we typically evaluate your current technology stack, design a clean data architecture for the migration and build the frontend in Shopify's theme or headless setup depending on your needs. The result is a platform you own commercially, not a codebase you are tied to through a single developer.
How to move forward
If you are sitting with an aging Umbraco webshop, or considering hiring an Umbraco developer to build a new store from scratch, we recommend assessing the total cost of ownership over time, not just the price of the first few hours. Factor in maintenance, hosting and security before you decide.
