Plan Changes

Subscribers can move to a different subscription plan at any time. Zotlo manages the billing logic (renewal dates, credits, charges) and delivers updated subscription details to your system so you can adjust user access accordingly.

Plan changes can be made:

• From the Zotlo Dashboard

• Via the Zotlo API

Zotlo does not enforce access rules, your app decides how to behave based on the updated subscription data.

Upgrade

An upgrade means moving to a higher-priced plan.

Zotlo supports two upgrade behaviors:

Reset Billing Cycle

The most common scenario for upgrades.

What happens:

• New plan starts immediately.

• A new billing cycle begins now.

• The remaining unused time on the previous plan is calculated.

• If the unused time has value, it is applied to reduce the amount charged for the upgrade.

• Result for customer: Instant access to the higher-tier plan.

Keep Current Cycle

The subscriber keeps the original renewal date.

What happens:

• New plan becomes effective immediately.

• The billing cycle does not reset.

• Unused time from the previous plan is prorated and difference is billed instantly.

• The subscriber pays only the pro-rated difference for the remaining days until next renewal.

• Result for customer: Immediate access with a small top-up payment.

Downgrade

A downgrade means moving to a lower-priced plan.

Zotlo always applies next-cycle activation for downgrades. (No immediate downgrades, no proration.)

What happens:

• The subscriber stays on the current plan until the end of the billing period.

• The downgrade becomes active on the next renewal date.

• No credit is created.

• Billing amount updates automatically on next renewal.

• Result for customer: They keep their current benefits until the cycle ends.

How Proration Works

When a credit is applicable:

• Zotlo calculates the value of unused days based on:

  • Previous plan price

  • Days remaining in the current paid period

• This credit is applied to the amount of the upgrade.

Proration applies only for upgrades. There is no proration for downgrades.

Trials During Plan Changes

If the subscriber is currently in a trial, changing plans typically ends the trial unless the new plan also includes a trial.
