The most expensive mistake of my career wasn’t a line of code; it was a “yes.” That day, my team and I said “yes” to writing our own ERP system from scratch. Despite years of development and immense effort, looking back today, there are moments when I think, “I wish we had just bought a ready-made solution.” This article is written to offer a pragmatic perspective, distilled from 20 years of field experience, to anyone burning with the desire to build their own platform.
The Allure of Building a Platform from Scratch
The idea of building your own platform feeds on that inner desire to “be an architect” that lies somewhere inside every tech person. Setting your own rules, creating a system that works exactly how you want, packed with the features of your dreams… This is incredibly attractive, especially when developing a startup or a new product. It feels like it will deliver a solution that is “completely tailored to us.”
We set out on this path while developing a manufacturing ERP. Our goal was to bring everything under one roof, covering everything from supply chain integration to operator screens, and even AI-powered production planning. We started with a FastAPI backend on PostgreSQL and a Vue/React frontend. We envisioned an architecture that would directly mirror our data flow—buy, produce, ship, invoice. This was less about software architecture and more about digitizing organizational workflow.
However, this journey wasn’t just about writing code. We also had to dive deep into many different areas, such as system security, network configuration, server management, and container orchestration. The fact that each component was a world of its own multiplied the scale and complexity of the project exponentially.
The Overlooked Power of Ready-Made Solutions
But what about ready-made solutions? We all know that there are countless off-the-shelf solutions on the market, from ERPs to CRMs, project management tools to communication platforms. Using them might initially feel like “it’s not exactly what we want.” But this feeling is usually superficial.
For instance, when developing the ERP for a manufacturing company, the initial mindset was to build our own system. However, when we analyzed the existing solutions on the market in detail, we found systems that met our core workflows (production planning, inventory management, shipment tracking) and even offered advanced reporting and analysis capabilities for some of them. Most of these solutions had been shaped by years of experience, with security vulnerabilities patched and performance optimizations already made.
Choosing a ready-made solution can drastically reduce development time and cost. Moreover, because these platforms generally have a large user base, they are rich in community support and documentation. This makes it much easier to find solutions when we encounter problems.
The True Cost of Building Your Own Platform
The decision to build your own platform is not limited to the initial development cost. It also means a continuous burden of maintenance, updates, and upgrades. The tech stack we once saw as “the best” can start to become obsolete within a few years. As new security threats emerge, we must constantly update our system.
On the system administration side, struggling with the complexity of Linux services (systemd units, journald logging), PostgreSQL database tuning, Redis, and Nginx, while trying to add new features, was a true balancing act. Although container orchestration (like Docker Compose) made things slightly easier, hybrid bare-metal and container deployments brought their own unique challenges.
Another cost of this decision is the “opportunity cost.” The time and energy you spend building your own platform could have been spent focusing on your core business, improving customer relationships, or strengthening your marketing activities.
When Should You Build Your Own Platform?
Of course, choosing ready-made solutions might not always be the right move. In some cases, building your own platform is the only option or the most logical path. These situations generally include:
- Unique Needs: If you have highly specific and niche requirements that none of the existing solutions can meet.
- Competitive Advantage: Situations where the platform you build will directly provide a competitive advantage to your business. For example, a financial calculator side-product we developed stood out by offering features different from other tools on the market.
- Strategic Importance: When the platform is critical to the company’s strategic goals and depending on an external vendor is unacceptable.
- Deep Technical Expertise: If your team has the depth of technical knowledge and experience required to build and manage a complex platform from scratch.
Even in these cases, it is vital to carefully evaluate the trade-offs and understand the potential risks.
Conclusion: Pragmatism Always Wins
My 20 years of experience has taught me this: in the world of technology, there is no such thing as “the best”; there is only “the most suitable for the situation.” No matter how attractive the idea of building your own platform is, you must always consider its cost, time, maintenance burden, and most importantly, the “opportunity cost.”
Most of the time, using robust and mature solutions on the market allows you to move faster, keep costs under control, and focus on your core business. The decision to build your own platform should only be made when it is a truly strategic necessity and all risks have been carefully evaluated.
So, what do you think? Building your own platform or using ready-made solutions? What was the most expensive “yes” in your career?
