You switched plans.
You expected a clean new price.
Instead, your next auto-payment looked… wrong.
Higher. Or slightly different. Or not matching what you saw on the pricing page.
Plan Price vs Auto-Pay Amount — They’re Not Always the Same
When you change a subscription, billing systems recalculate more than just the base price.
- Prorated charges for remaining days
- Unused credit from previous plan
- Immediate upgrade difference
- Regional tax adjustments
- Currency conversion rounding
The number you see isn’t always the new plan price — it’s a transition calculation.
Common Scenarios That Change Auto Billing
- Monthly → Annual switch (full year charged instantly)
- Upgrade mid-cycle (difference charged immediately)
- Downgrade with credit applied later
- Trial → Paid conversion timing overlap
Each scenario changes the billing math.
How To Verify The Correct Amount
- Check previous invoice balance
- Look for “proration” line items
- Confirm tax region settings
- Review renewal date shift
If the math matches the adjustment period, it’s likely correct.
When It’s Actually A Billing Error
- Duplicate renewal without plan change
- No proration details listed
- Amount exceeds advertised annual rate
- Tax applied twice
In those cases, contact support with invoice ID — not just a screenshot.
Plan changes don’t just update features.
They reset billing calculations.
And auto-pay reflects that recalculation — not just the sticker price.
