What each product does

FlyCode is a revenue recovery platform for failed payments and involuntary churn: Recover, Reach, Retain and AI Agents. Recover replaces the native retry schedule with a per-merchant model trained on your own transaction history and on Visa and Mastercard network data, retries other valid cards on file when the primary fails, catches failed trial conversions, and enforces network retry rules. Reach coordinates email and SMS with the retry schedule and wins back cancelled customers. Retain prioritizes high-value accounts, extends recovery past the billing platform’s window and sets the rules for what happens when recovery runs out. AI Agents watch your billing around the clock for revenue leaks and route payments across providers. It runs on Stripe, Chargebee, Shopify, Recharge, Skio and Loop, and pricing is on recovered revenue above your existing baseline.

Stunning is dunning software for Stripe that has been in market since 2012, with Foxy and Subbly supported at a reduced feature set. Its advice is to keep Stripe’s retries on and switch Stripe’s customer emails off: Stunning then sends up to eight failed payment emails and SMS you write yourself, each more urgent than the last, CCs every billing contact, shows a notice inside your app, warns about expiring cards at 30, 15 and 7 days, links to a card update page on your own domain, and keeps sending a win-back sequence for months after Stripe marks the subscription unpaid. It can ask customers to add a backup card in exchange for a discount and charge it when the main card fails, and it adds its own retries on top of Stripe’s over up to 21 days. Pricing is a flat monthly fee tied to your MRR with no share of recovery, and a Managed Recovery service has Stunning’s team run it for you after a paid audit. There is no per-merchant model, no card network partnership, no trial recovery and no cancellation flow, and the published figures are lifetime totals rather than a rate above a baseline.

When Stunning is the better fit

Pick Stunning if the messages are your problem. A small Stripe business whose customers get one generic Stripe email and ignore it will see an improvement from eight well-written ones, SMS and an in-app notice, and the flat fee is easy to budget. It is also one of the few options on Foxy or Subbly, and the Managed Recovery service suits a team that wants a person watching the inbox. The trade is that the retries, which recover most failed payments silently, stay exactly as Stripe runs them, and Stunning’s extra attempts stack on top of that schedule rather than improving it.

When FlyCode is the better fit

Pick FlyCode if you want the failed payment recovered before anyone has to read an email. A model trained on your transactions and on Visa and Mastercard network data decides each retry from the first attempt, other valid cards already on file are tried without asking the customer to add one, and email and SMS go out only when the retries need help, timed to the customer’s local time. That moves the recovery rate on the silent majority, keeps one schedule within network rules, and is charged only on the lift above your baseline. It is also the only option of the two for trial recovery, high-value prioritization, revenue leak monitoring, and billing through Chargebee, Shopify, Recharge, Skio or Loop.

Can you run both?

Not for retries. Stunning’s retries would stack on FlyCode’s schedule the same way they stack on Stripe’s, and two systems retrying the same card is what issuers penalize. Keeping Stunning for its email templates alone is possible, but FlyCode’s Reach already sends email and SMS coordinated with the retry outcome, which a fixed sequence cannot do, so most teams switch rather than combine.
