About

GreatWait schedules one-off and recurring HTTPS callbacks for apps and AI agents. Create and manage schedules through an API, CLI, remote MCP server, or web dashboard. View delivery history, retry failed deliveries, and cancel, pause, or resume schedules. Controlled bulk operations help manage multiple schedules, while forecasts of upcoming deliveries support capacity planning. Pricing is usage-based at $1 per 100,000 delivery attempts, including retries, with a $10 minimum prepaid purchase. New users receive $1 in trial credit valid for 14 days. The service is designed for technical teams that need scheduled delivery to external HTTPS endpoints.

About

Most failed subscription payments don't come back on a retry. Expired cards, 3D Secure requests and generic bank declines need the customer to act, and most customers never notice the payment failed. Rebounce connects to Stripe, Paddle or Square in a few minutes. When a payment fails, it reads the decline code, retries only when a retry can work, and sends the customer a short sequence by email, SMS or WhatsApp with a link to a page where they update the card or confirm 3D Secure. No login needed. The sequence stops the moment the invoice is paid. In our own data, 44% of customers who opened the payment link paid on that page, while automatic retries recovered 5.5%. Also included: card expiry warnings 30 days ahead, weekly recovery reports, and a free 90-day audit of your Stripe account (read-only, no signup). Pricing is flat: Starter $3.50/month, Growth $14/month, Scale $39/month. No percentage of recovered revenue.
