Hi, we use stripe subscriptions now quite a lot, and I'm a bit worried about the whole invoice pricing - could you please clarify that a bit? the web site says invoices are free for up to first 2K, then $1 per invoice. our recurring charges to customers now are around $2.99 per month, I hope you're not planning to take $1 more away from that. does the invoice price apply for each recurring payment cycle, or am I reading something wrong here?
