What is Total Cost of Ownership (TCO)?

Home > Glossary > Total Cost of Ownership (TCO)

Total cost of ownership (TCO) is the full cost of operating a technology solution over time, not just its initial implementation price. For ecommerce, TCO can include licenses, development, integrations, hosting, support, upgrades, maintenance, staffing, and operational overhead.

For ecommerce, license price is only one part of the cost. A lower subscription can still produce a higher TCO if the platform requires extensive custom development, expensive integrations, specialist support, or frequent workarounds. Conversely, a platform with a higher license may reduce engineering and operational cost when critical capabilities are native.

An ecommerce TCO model should include:

• Platform licenses, hosting, infrastructure, transaction or usage fees, and third-party services.

• Implementation, customization, migration, integration, testing, and ongoing development.

• Support, monitoring, security, upgrades, incident response, and technical-debt remediation.

• Internal operating cost and the business impact of slow releases, downtime, or manual processes.

TCO is most useful over a multi-year horizon and across realistic scenarios. It should not be manipulated by excluding the costs that make one option look inconvenient. During platform selection or replatforming, comparing three- to five-year TCO alongside capability fit and risk gives a better decision basis than headline license pricing alone.

Example: A platform with lower license fees can still be more expensive over five years if it requires custom B2B pricing, several paid apps, specialist maintenance, and frequent integration workarounds.
