How We Bill
We bill monthly based on usage. Each month your bill is determined by the total income that's been added to IC in the 30 days since your previous bill (or since account creation, in the case of a first bill).
(Note! The date of the transactions themselves is not relevant, only when it was added to your account - this allows us to account for older transactions right alongside newer transactions.)
Once the bill is assessed, you'll get an invoice via Stripe breaking it down - you can also find this invoice + past bills in IC, in Account -> Billing. Your card won't be charged right away - the invoice is payable within 15 days, and only then will the card on file will be run. This 15 day lag is there just in case there's something incorrect about the income added to your account - any issues, just reply to the invoice or email firstname.lastname@example.org, and we'll be happy to get things straightened out.
