Build vs. Buy Calculator

What costs you should factor into a build vs. buy decision?

A well-rounded build vs. buy consideration goes beyond the initial development. Some essential build vs. buy criteria include initial build time, ongoing maintenance and infrastructure, SaaS subscription or license fees, and the opportunity cost of engineering resources.

Why you should use the Build vs. Buy Calculator?

The Build vs. Buy Calculator gives e‑commerce teams clarity. It turns a high-stakes, complex decision into a clear, numbers-backed picture.

The calculator helps you understand the trade-offs

Building search software gives full control over how products are ranked, recommended, and surfaced. Custom relevance can set your brand apart, but it’s resource-intensive, requires ongoing optimization, and mistakes in ranking logic can directly hurt revenue.

Third-party solutions come with proven relevance algorithms, built-in analytics, and vendor support, ready to be connected to your tech stack. They reduce operational risk, speed time-to-market, and ensure consistent search quality but offer less flexibility to experiment with custom algorithms.

You can see the long-term impact

Smaller teams or limited engineering bandwidth often spend months, or even years, before a custom search delivers ROI. Our calculator shows whether building is a viable investment or a slow drain on resources.

For fast-growing catalogs or high-traffic stores, buying usually makes more sense. Proven technology and analytics free your team to focus on growth rather than maintaining core search infrastructure. The calculator quantifies long-term benefits like cost savings, reliability, and time-to-value.

Tailor it to your context

The decision isn’t one-size-fits-all. Factors like growth trajectory, unique UX needs, or an innovation-focused roadmap can flip the balance toward buying or building a custom search engine.

The calculator lets you tweak variables such as monthly hosting costs, number of employees, and feature complexity to see how each factor changes the outcome, helping you choose the path that delivers the best balance of cost, control, and performance.
