Regular users must add a credit card to their account in order to process projects. That credit card will be charged per project submitted. Another option is to prepay a certain amount and run your projects against that balance.
Enterprise users will be invoiced on the first business day of each month for projects run the month prior. That invoice can be paid using:
- ACH / Bank transfer
- Credit card
Enterprise users can also prepay, using one of the methods above, and run projects against the prepaid balance. Read how to add a payment method.
