How stability study billing works
Last updated: October 9, 2026
Stability studies are billed per time point, so you only pay as testing is completed.
Per time point
Each time point is billed on its own when it completes. You aren't billed for the whole study up front. The approved quote says the same: "Each time point will be billed independently upon completion."
Where to see costs
On the Schedule step, each arm shows a subtotal, and the running total stays at the bottom of the page.
On the Analytes step, you can see the cost of one time point across all the tests you selected.
On the Review step, you can see the cost of each time point and each test.
T0 on the accelerated arm is free
If you run real-time and accelerated together, both arms share the T0 result. The accelerated arm reuses the real-time T0 result, so you aren't charged for it twice.
