An upgrade in Zoho Billing is a subscription plan change where the customer moves to a plan with a higher price or greater feature set. Upgrades typically happen when customers outgrow their current plan’s capacity or want access to premium features. Zoho Billing handles the plan transition, calculates proration for the mid-cycle change, and begins billing at the new plan’s rate from the upgrade date.
Upgrades can be initiated by the customer through the customer portal or by an admin through the Zoho Billing interface. When an upgrade occurs, Zoho Billing prorates the remaining days on the old plan and charges for the remaining days on the new plan, creating a net adjustment. The customer’s subscription then renews at the new plan’s full price on the next billing date.
Zoho Billing can be configured to apply upgrades immediately (customer gets access to the new plan’s features right away, with proration handled now) or at the end of the current billing cycle (no proration, customer continues on the old plan until renewal). Immediate upgrades are more customer-friendly as there is no delay in accessing new features. End-of-cycle upgrades simplify billing by avoiding mid-cycle adjustments.
Yes. You can apply a coupon to an upgraded subscription either manually (admin-applied at the time of upgrade) or through an automated workflow. For example, if a customer upgrades from Monthly to Annual, you could apply a coupon that reflects an additional loyalty discount. Coupons can be applied to the subscription regardless of which plan it is on.
Yes. If a customer upgrades their plan during a trial period, Zoho Billing typically ends the trial and starts the paid subscription immediately at the new plan’s rate. The assumption is that the upgrade signals readiness to pay. The trial end action you configured for the original plan may influence exactly how the transition is handled, so verify your settings if trial-to-paid upgrade flows are a key use case.
