From perpetual licenses to open source: the cost model that changes your P&L
Open source is not free, but it stops charging you for breathing.
A perpetual license is paid once, but the 20% annual support and the renewals never end. An open-source engine changes that model: no license, with optional support you contract as a service rather than as permission to use it. For a CFO, it is not just savings; it is a cleaner, more predictable P&L.
01 Support stops being a fixed tax
In the proprietary model you pay annual support on the license no matter what. With open source you contract support as a service, and only the support you need.
02 Less CapEx tied to one vendor
Perpetual licenses lock capital to a platform. Without them, that capital is free to go where it actually earns a return.
03 Spend becomes predictable
With no surprise renewals or licensing audits, the engine cost stops being a variable that is hard to budget.
04 Invest once, save every year
The migration is a one-time outlay. The license and support savings repeat every fiscal year, and that is what moves the P&L.
// A typical case (illustrative)
Picture a company that renews ~USD $40,000 a year in perpetual-license support for a mid-sized database server. Moving to open source, that line item disappears and it contracts support as a service only when it needs it. On the P&L, a fixed recurring cost becomes a much smaller, controllable variable expense.
Illustrative example with typical market figures, not a specific client.
// next step
Ask for a three-year cost comparison between your current model and open source, with the impact on your P&L. At dba.mx we do it at a fixed price with a firm cap, so the migration is predictable too.
