An operational breakdown analyzing total cost of ownership, data ownership, scalability, and long-term business flexibility.

Evaluating Total Cost of Ownership

Commercial SaaS software offers fast initial deployment, but monthly per-user costs scale indefinitely as your workforce expands.

Custom software requires an upfront engineering investment, but eliminates ongoing per-seat monthly subscription fees and gives your company complete ownership over application IP and data.

When SaaS Makes Sense vs. When Custom Wins

SaaS tools are ideal for standardized commodity functions (such as basic email or accounting).

Custom software is essential for proprietary core workflows, custom client portals, specialized logistics tracking, and unique business models.
