Dunning

When a subscription billing attempt fails, Gro’s dunning system automatically retries the charge on a configurable schedule. This helps you recover revenue that would otherwise be lost to expired cards, insufficient funds, or temporary payment issues.

Dunning only handles payment problems. If Shopify can’t charge an order because of stock, Gro holds the order for you instead of retrying it. See Held orders and stock.

How It Works

1. A subscription billing attempt fails
2. Gro creates a dunning episode — a record that tracks the retry journey
3. Automatic retries are scheduled based on your configured intervals
4. If a retry succeeds, the episode is marked as recovered
5. If all retries are exhausted, Gro applies a final action (pause, cancel, or keep active)

Episode Statuses

Status	Meaning
Ongoing	Active dunning — retries in progress
Recovered	Payment succeeded after retries
Lost	All retries exhausted — revenue not recovered

Configuration

Go to Settings → Payment retries in the Gro dashboard:

Retry Schedule

Define when retries happen after the initial failure. For example:

• Retry 1: 3 days after failure
• Retry 2: 5 days after retry 1
• Retry 3: 7 days after retry 2

Final Action

Choose what happens when all retries are exhausted:

Action	Description
Pause	Subscription is paused — can be resumed when payment is updated
Cancel	Subscription is cancelled — can be reactivated via winback
Keep active	Subscription stays active — billing will be attempted again on the next cycle

Events

Dunning episodes generate events you can use in email flows:

• dunning:started — first failure, dunning begins
• dunning:recovered — payment succeeded after retries
• dunning:lost — all retries exhausted

Use these events in Gro Flows or Klaviyo to send payment failure notifications and payment update reminders to customers.
