Build cost is components times weeks times 40 hours times your rate, discounted by the AI speed-up. Maintenance is charged on the full code surface, because AI writes the code faster but does not make it smaller. Salesforce ships three platform releases a year, Spring, Summer, and Winter, and any of them can touch LWC, Apex, or Flow runtime; API versions are supported for about three years, then retired in waves. That cadence is what maintenance pays for, and it does not care whether a human or an AI wrote the code. GitClear's 2026 analysis of 623 million code changes from 2023 to 2026 found code block duplication at its highest level on record, up 81 percent since 2023, while refactoring fell to 3.8 percent of changed lines and updates to code older than a year dropped 74 percent. The trend runs through 2026, not just the early Copilot years: AI-era code gets more duplicated and less consolidated, which is what maintenance is charged against. The Avonni side is all-in: one-time config of about 6 hours per component with no Apex and no test classes to write or keep at the 75 percent coverage bar, plus the real subscription over your horizon. The managed package passed the Salesforce Security Review and carries its own coverage and maintenance. One subscription covers the whole suite, so it does not scale with your backlog the way custom code does. The defaults are conservative starting points, not claims. Move every slider to your own numbers.
