FAQ
What are credits and how do they work?
Credits are a dollar-denominated balance used to pay for usage across all Inworld products. When you subscribe to a paid plan, you receive credits equal to your plan price at the start of each billing cycle.
Do unused credits roll over?
Unused subscription credits roll over automatically for up to 3 months, as long as you have an active paid subscription and a plan of equal or higher value.
What happens if I go over my credits?
You can purchase additional credits or enable auto-reload to automatically add credits when your balance drops below a threshold you set.
What happens when I upgrade, downgrade, or cancel my subscription?
Your upgrade takes effect immediately. You will be charged the full price of your new plan, plus any unbilled usage. Unused credits carry over to your new balance.
