Pay for what you use.
Every paid tier includes an event processing cap. If you exceed it, a simple per-event overage applies — and it gets lower as you move up tiers. Soft limits: no mid-cycle cutoff, billing accuracy never compromised.
| Tier | Event Cap | Overage Rate | % of Revenue | Example |
|---|---|---|---|---|
| Sandbox | 10K/mo | Hard cap | N/A | Test environment only |
| Starter | 500K/mo | $0.30 / 1K events | 0% (under $250K) | 750K events = $199 + $75 |
| Growth | 5M/mo | $0.25 / 1K events | 0–0.20% | 7M events = $449 + $500 |
| Business | 25M/mo | $0.12 / 1K events | 0–0.15% | 30M events = $899 + $600 |
| Enterprise | Unlimited | Included | Negotiated | Custom agreement |
Volume-based pricing that scales with you.
Competitors charge revenue percentage from dollar one. BillAI only participates once you're meaningfully scaled — and always at a lower rate.
For companies processing over $250K/month in billing volume (up to $3M ARR), a small revenue percentage applies on a marginal basis. The rate decreases as your volume grows — the more you process, the lower your effective rate.
Marginal calculation — each bracket applies only to volume within that band (like tax brackets).
Worked Example
$3M/month/mo on Growth tier:
The right tier for your scale.
Each tier includes a recommended billing volume threshold. These are guidance, not hard caps — the revenue percentage captures value at any volume. But features are designed for the scale they serve.

Enforcement approach
Stage 1 — Nudge (soft): Dashboard notification when billing volume exceeds tier threshold.
Stage 2 — Feature friction (natural): Tier feature limits create organic upgrade pressure.
Stage 3 — Personal outreach (after 3 months): Conversation, not cutoff.
