Each KioskBuddy plan comes with a base amount of transactions per month (or year), and anything beyond that incurs an overage fee. Depending on your plan, this transaction count resets monthly or yearly. The overage fee amount depends on your plan tier as well as payment frequency. For example, yearly plans come with a discounted overage fee of 50% off. Check out KioskBuddy's Pricing page for exact pricing details.
Only transactions that happen on your kiosks apply to your plan's count. In other words, other transactions made elsewhere on the Square platform, like online ordering, don't affect your costs. Note that any refunded transactions are still counted towards your plan's transaction count.
For high volume businesses, you can also reach out to sales@kioskbuddy.app for custom pricing with even better rates.
