Total cost of ownership
Total cost of ownership (TCO) is the full lifetime cost of a product or decision, not just its sticker price. For software, that means the subscription plus onboarding time, integration work, training, internal admin, and the cost of switching away later. TCO matters to founders on both sides of the table. As a buyer of tools, it stops you choosing the cheapest licence that quietly eats weeks of setup and lock-in. As a seller, framing your offer against a competitor's TCO is often a stronger argument than price: a higher monthly fee that removes a fortnight of implementation and a headcount's worth of admin is genuinely cheaper to own. For a lean founder watching every pound and every hour, TCO is the honest way to compare options, because the line item on the invoice is rarely where the real money goes. Cost your decisions on the full picture, not the headline number.
