Example monthly cost (Starter)
| Fee-bearing orders | Monthly cost |
|---|---|
| Up to 50 | $5.00 (base) |
| 100 | $10.00 |
| 500 | $50.00 |
| 1,000+ | $99.99 (capped) |
The $5 base covers your first 50 orders. After that, each extra fee-bearing order adds $0.10, until the total is capped at $99.99/month.
What counts as a billable order?
Counts:
- A completed order where a TackOn fee was applied
Never counts:
- Orders without a TackOn fee
- Abandoned carts
- Test orders
- Orders during your free trial
Why usage-based?
- Fair — Pay only when a fee is actually collected
- Scalable — Grows with your revenue, never ahead of it
- Low risk — No minimums, cancel anytime
- Capped — Never more than $99.99/month
