## Best for

Failed charges with the attempt history under each row, a Retry now that flips status to Retrying and a templated contact dialog

## Agent notes

- `getRecoveryStats` reads the static `PAST_DUE_INVOICES`, so the stat strip does not move when Retry now changes a row
- `markRetrying` only flips status to Retrying in state and never appends to `attempts`, so the attempt history does not grow
- `handleRetryAll`, `handleExport` and `handleRules` in the header only toast; the grid's own `handleRetryDue` is what flips status

## When not to use

- A full invoice ledger with bulk collector assignment and a void action: use [Invoice Ledger](https://web.dev.reui.io/blocks/solutions/billing/solution-billing-1.md) (`get_block("solution-billing-1")`)
- One customer's account with its invoices, payment methods and activity: use [Billing Account Detail](https://web.dev.reui.io/blocks/solutions/billing/solution-billing-4.md) (`get_block("solution-billing-4")`)

## About Billing blocks

### When to use

- A back office for billing operators: the invoice ledger, subscriptions, a dunning queue and metered usage
- Plan and discount admin: editing the plan catalog and coupon rules, or moving a subscription to a new tier
- One customer's billing account seen by staff, or an invoice built line by line and then sent

### When not to use

- A public page where visitors compare plan tiers and pick one before signing up: use the [Pricing blocks](https://web.dev.reui.io/blocks/marketing/pricing.md)
- A signed in customer's own settings page showing their plan, usage and invoices: use the [Profile blocks](https://web.dev.reui.io/blocks/application/profile.md)
- A stepped intake flow with no money in it, such as vendor onboarding or team invites: use the [Wizard blocks](https://web.dev.reui.io/blocks/application/wizard.md)

### Agent notes

- Each block sets a `min-h-svh` wrapper with `bg-background`, padding and a max width in page.tsx or its root component; drop it inside an app shell
- No block calls an API: sends, retries, saves and exports update `useState` or fire a sonner `toast`; post to your billing backend from those handlers
