Phase 2: Twilio Rebilling + Request Payment Flow
Phase 2 will add a new Billing tab in Sub-Account Settings where your customers will be able to enter their credit card information, enabling you to activate Twilio Rebilling which will auto-charge the client for Twilio credits and auto-recharge them when they get low.
You can even add a margin so that each time they are charged for more credits, you make a percentage!
Phase 2 also includes a new "Request Payment" link generator, making it easy to email or text the request link to your clients to get them to enter their credit card.
