Does an upsell app's subscription cost scale with what it actually generates?

Is 10% a coincidence across ReConvert's tiers, or is that how the app is priced?

The app's own listing doesn't state a percentage-of-revenue pricing model explicitly; it publishes flat monthly prices with order-or-revenue thresholds. The 10% figure is Agentis's own division of each published price by its own published threshold, and all three tiers land at the same ratio, whether that reflects deliberate pricing design or coincidence. The published tiers are Upsell Basic at $4.99 for up to 50 orders or $50 in upsell revenue, Upsell Growth at $9.99 for up to 100 orders or $100, and Upsell Business at $19.99 for up to 200 orders or $200. The listing also states that charges increase beyond these thresholds based on monthly order volume or upsell revenue, whichever is higher, so the tiers are boundaries rather than a hard cap. A flat subscription reads as a forgettable fixed cost; a consistent 10% cut of incremental revenue reads differently. To apply this to your store, divide your upsell app's monthly charge by the upsell revenue it generated last month and see whether the ratio still makes sense at your volume.
