What is the SaaS Tax?

The SaaS tax is the compounding cost of per-seat licensing. As your headcount grows, you pay more for the exact same software, resulting in hundreds of thousands of dollars in overpayment over 3-5 years.

How does custom software save money compared to SaaS?

Custom software requires a higher upfront capital expenditure (CapEx) but eliminates compounding monthly operational expenses (OpEx). After the break-even point (usually 18-24 months), custom software generates massive ROI because it costs the same whether you have 50 employees or 5,000.

Why This Happens

SaaS relies on a compounding Per-Seat Penalty. As you grow, you are brutally taxed for your success. You pay more for the exact same code execution just because you hired more people. Custom software turns this operational expense into a flat, owned asset.
