Stop Paying the Intercom Tax: When to Build Instead of Buy

Source: Dev.to

The Problem with Per-Seat Pricing

Unlike infrastructure costs that benefit from economies of scale, per‑seat SaaS licensing scales linearly with your headcount. A mid‑market company with 30 users on Intercom can easily pay $14,040 – $50,040 per year in licensing fees alone.

Over five years, that is nearly a million dollars for software that you do not own, that limits your data access, and that forces your team to adapt to generic workflows.

Calculating the Break‑Even Point

We wanted to quantify exactly when a company should stop renting and start building. We analyzed 22 major SaaS platforms to map their 5‑year total cost of ownership (TCO) against the cost of building and maintaining a custom software solution.

The results are eye‑opening. For many mid‑market teams, the break‑even point for custom software is under six months. After that initial build cost, adding new users costs essentially nothing.

What You Get with Custom Architecture

Building internal tools or custom platforms used to be a massive risk. Now, with modern TypeScript stacks and AI‑native workflows, small engineering teams can deliver enterprise‑grade internal tools in weeks, not years.

Benefits

• Zero Per‑Seat Fees: You own the platform. Adding 100 new users costs nothing.
• Absolute Data Sovereignty: Your data stays on your infrastructure. No export fees or vendor lock‑in.
• Exact Workflow Fit: The software does exactly what your operations require, without the bloat of a one‑size‑fits‑all product.

I am curious to hear from other developers: at what scale did your team finally decide to rip out a SaaS product and build it in‑house?
