You only pay the prorated difference when upgrading plans. PaperSurvey automatically credits your unused time from the current plan, so you are never charged twice for the same period.

This fair billing approach means you can upgrade with confidence, knowing exactly what you will be charged.

How Upgrade Billing Works

When you upgrade mid-cycle:

1. We calculate your unused days on the current plan
2. Convert this to a credit amount
3. Apply it to your new plan cost
4. You pay only the difference

Real Example

Scenario: Upgrading from $20 Standard to $50 Enterprise plan

If you have used 15 days of your $20 plan:

• Credit for unused time: $10
• New plan monthly cost: $50
• Your payment: $40 (for the full month on Enterprise)
• Next month: Regular $50

The Math Behind Proration

We calculate daily rates for accuracy:

Current plan daily rate = $20 / 30 days = $0.67/day
Unused days = 15
Credit = $0.67 x 15 = $10

Common Upgrade Scenarios

Early in billing cycle: More unused time means a larger credit and lower upgrade payment.

Late in billing cycle: Less unused time means a smaller credit and higher upgrade payment.

Upgrading on renewal date: No proration is needed. You simply pay the full price of the new plan.

What About Downgrading?

The same fair system applies. Unused time becomes account credit that applies to future bills. No refunds are issued to your payment method.

Multiple Upgrades in One Month

If you change plans multiple times, each change is prorated. Credits and charges are calculated precisely, and the final charge reflects your actual usage.
