A failed charge is not a churn event. It becomes one when nobody works it. The clinics that recover the most are not the ones with the cleverest wording — they are the ones whose first contact goes out the same day, from an address the member recognises.
The ladder
- Day 0, within business hours: retry once, then email the member from the clinic address. Say which plan, which amount, and give a single link to update the card. Do not attach an invoice — it buries the action.
- Day 2: retry again. Cards fail for temporary reasons more often than people expect, and a second attempt two days later clears a meaningful share with no contact at all.
- Day 4: second email, different subject line, same single action. Add the consequence in plain words: the plan pauses on a stated date.
- Day 7: SMS if you hold consent for it. Short, no link-shortener, the clinic name in the first four words.
- Day 10: a call task for the front desk, with a script. This is the step most clinics skip, and it is the step that recovers the members worth keeping.
- Day 14: pause the plan, and say so. A paused plan the member can restart converts far better than a cancelled one they have to re-join.
What changes the outcome
- Send from the clinic, not from a billing processor. Recognition is most of the open rate.
- One action per message. Two links halves the response.
- Never threaten care. Payment follow-up and clinical care are separate conversations and members can tell when they have been merged.
- Catch expiries before they fail. A card expiring next month is a cheap, friendly message; the same card failing is an awkward one.
What to measure
Recovery rate per ladder step, not overall. If step 5 recovers nothing, your call script is wrong. If step 1 recovers almost everything, you are sending it too slowly for the rest of the ladder to matter.
