Vercel has switched Pro and new Enterprise customers from package-based to per-unit billing for Function invocations. The new rate is $0.0000006 per invocation, which is mathematically identical to the previous $0.60 per 1M invocations, but the billing structure changes starting your next cycle.
The shift matters because per-unit billing stops teams from burning through large monthly usage credits in single bursts. Small teams with uneven workloads no longer pay for capacity they do not use, and large teams do not hit artificial package ceilings.
The full changelog details how existing customers are protected through their current billing cycle and what the transition looks like for Enterprise. If your infrastructure cost model depends on Vercel Functions at scale, the pricing and usage documentation is worth reading before your next cycle begins.
