Pricing
Start free. Upgrade only when you grow. You keep 100% of every fee you collect.
Two ways to run TackOn
Free plan: $0/month
- 20 fee-bearing orders per month, free forever
- All surcharge types, rules, and widget templates
- Multi-currency support
- No credit card required
Starter plan: $5/month
- Includes 50 fee-bearing orders per month
- $0.10 for each additional order beyond 50
- Total billing capped at $99.99/month, so you'll never pay more
- 30-day free trial, full access, no credit card (one trial per store)
- Cancel anytime from the Billing page, which puts you back on the free plan with a credit for the unused days
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
Billing
All billing runs through Shopify:
- Appears on your regular Shopify invoice
- No separate payment setup
- Track everything in your Shopify admin
