Frequently Asked Questions

What exactly is the "Fair Pass"?

expand_more

The Fair Pass is designed for makers who only need advanced features seasonally. Maybe you have a big craft fair coming up in November? Buy the pass for $12, get 45 days of "Pro" features to price your items and print invoices, and then return to the free plan automatically. No subscriptions to cancel.

Can I upgrade from Hobbyist later?

expand_more

Absolutely. All your data is saved. If you hit the machine limit or need advanced math features, you can upgrade to Pro or grab a Fair Pass instantly from your dashboard.

Do you offer refunds?

expand_more

No, but you can cancel your subscription anytime right from your account settings. The Fair Pass automatically expires at the end of 45 days, so no cancellation is required for that.
