What is Build vs Buy?

Build vs Buy is the strategic decision of whether to develop a software capability in-house or purchase it from a vendor. The build vs buy software question applies to anything from a CRM to a website to a custom workflow tool. The right answer depends on how core the capability is to the business, how unique the requirements are, and the total cost of ownership over time — not just the sticker price up front.

Why it matters

The default answer of buy keeps winning because it sounds safer. Faster to deploy, predictable cost, someone else maintains it. That logic holds for commodity tools — payroll, helpdesk, email. It collapses the moment the capability becomes part of how you compete. A scale-up that buys a generic website builder for its brand-defining homepage is renting the most important real estate it owns. A team that buys a content platform that needs a developer to publish a blog post just paid for a ticket queue. Buy commodity. Build what matters. The middle is where companies waste years and millions.

How it works

Score the capability on two axes. First, how strategic is it — does it shape how customers experience the brand, or is it back-office plumbing. Second, how unique are your requirements — can a standard product cover ninety percent of the need, or are the edges where the value lives. Strategic plus unique is build. Commodity plus standard is buy. The middle quadrants need honest math: total cost over five years, internal team capacity, vendor lock-in risk, and the cost of switching. The website almost always lands in the build column for any company where brand and conversion drive revenue.
