Total cost of ownership
$1,050,000 of this is change-request and migration cost. On SMART360, changes like these are configuration included in the subscription.
Uses your own figures for planning. For your real vendor costs, ask for a two-year change-request and services log.
Total cost of ownership, or TCO, is the full cost of running a billing platform over its life, not just the price on the contract. It includes the annual license and maintenance, the cost of every change the vendor bills for, periodic upgrades, data migrations, and the training that comes with each. The sticker price is only the part you see on day one.
The gap between the sticker price and the real cost is where budgets get broken. A platform that looks affordable at signing can cost several times its license fee once the change requests start.
On many legacy billing platforms, routine work becomes a billable change request. A new rate tier, a new bill format, an added customer class, or a new report can each turn into a separate charge with its own quote and timeline. Over ten years, a utility that changes rates and adds reports every year pays this tax again and again.
This is the cost that surprises utilities, because it is not on the contract. It is the reason the utility billing software architecture matters as much as the license price. A platform where changes are configuration costs far less to live with than one where every change is a project. For a deeper look at the numbers, see the guide on total cost of ownership of utility billing software.
The calculator adds up three parts of the cost over the years you choose: the base software cost, the change-request tax, and any major upgrade or migration.
Not sure what your change requests cost?
Each input reflects a real line in your budget, so use your own figures where you have them:
If you do not know your change-request cost, ask your vendor for a two-year log of change requests and services. That document is the most honest cost projection you will get.
On SMART360, the changes that become billable projects elsewhere are admin configuration instead. A rate change is an admin task, not a procurement event. New bill formats, customer classes, and reports are built in the platform, not quoted as change requests. That is why the change-request tax in this calculator drops to zero on SMART360, and why the platforms that avoid it cost far less to live with, as the guide on the risks of outdated utility billing software explains.
Version migrations follow the same pattern. There is no major migration project every few years, because the platform updates continuously as part of the subscription.
TCO includes the annual license and maintenance, the cost of change requests such as rate changes and new reports, periodic upgrades and migrations, and the training that goes with each. It is the full cost of running the platform, not just the contract price.
Because routine changes become billable change requests. Each rate change, bill format, or report can carry its own charge, and those charges repeat every year. Over a decade they can add up to more than the software license itself.
On SMART360, changes that are billable projects elsewhere are configuration included in the subscription. Rate changes, new formats, and reports are done in the platform, and there is no separate migration project, so the change-request tax drops out of the total.
