Pre-paid billing and/or adjustments to mid-month payment frequency

I’ve started using some of the more advanced models and quickly realized that my AA is going to get flooded with a large volume of invoices for small dollar amounts ($20–$50 at a time).

I’m not sure what the ideal solution is, but it would be nice to have some way to either pre-pay for credits (like OpenAI) or have some enrollment process to become a post-paid account.
