Tier Classification Discretion
What it looks like: "Your usage tier is determined at our sole discretion."
The Trap
- The T&C doesn't define what usage corresponds to which tier. They can move you up (and raise your price) arbitrarily.
- There's no appeal process because it's "sole discretion" — you have no recourse.
- Even if thresholds exist, they can be changed at any time. A 1,000 API-call "basic" tier today could be a "premium" tier tomorrow.
- Some services apply reclassification retroactively, billing higher rates for past usage.
How to Spot It
| Check | What to Look For |
|---|---|
| Criteria | Are tier thresholds clearly stated? If no numbers exist, trap. |
| Discretion | "Sole discretion" = upgrade without your consent. |
| Notice | Will you be notified before the change? Or find out on your bill? |
| Downgrade | Can you move back down if reclassified? |

Your Action Plan
- If you see "sole discretion" + "tier" → this is a trap.
- Look for defined thresholds: "Basic = 0-500 units." If no numbers, assume any usage can trigger upgrade.
- Before a usage spike, check your current tier's limits.
- Screenshot the pricing page at sign-up for reference.
