It would be good if credits rolled over each month as Creator plan is priced at US$49 or NZ$85 per month which is expensive for a small creator that makes almost next to nothing making content. Also for that expensive price you would expect better. Rolling over credits would fix that issue and would be a good act of faith for the people who choose to use your service. ElevenLabs have the same policy as you, but charge US$22 or NZ$38 per month. Just suggesting something. I have already accepted that I can just subscribe and do 25 breakdowns in the month and save to a word document, that way I don't lose out on anything.
