Build vs Buy

Your product needs customer chat.

The team could:

Build it

Create messaging, notifications, storage, moderation, and search.

Or:

Buy it

Integrate an existing chat provider.

Which should you choose?

Do not ask only:

Which is cheaper this month?

Build vs buy is usually a longer-term product decision.

You are choosing where your company should spend attention.

Building becomes more attractive when the capability:

• differentiates the product
• is strategically important
• needs unusual control
• would be expensive or limiting through vendors

If messaging is the heart of your product, owning it may matter.

Buying becomes more attractive when the capability:

• is common infrastructure
• does not differentiate you
• would take significant maintenance
• is already solved well by specialists

For many teams, payments, email delivery, or error monitoring fit this category.

Buying also creates dependencies:

• pricing changes
• outages
• missing features
• data restrictions
• switching cost

“Buy” does not mean “no engineering.”

It means choosing a different set of problems.

Ask:

Is this capability part of why customers choose us?

If yes, think carefully before outsourcing too much of it.

If no, ask whether building it is really the best use of your team.

Build vs buy is not just a cost decision.

It is a decision about where your company should own complexity.
