## TL;DR

The payout failed because the bank account on file is wrong: a typo, a closed account, or a missing field. Have the employee verify and update their banking details in the expense tool, then re-run the payout for the failed batch.

## Error

```text
reimbursement payout failed: bank details invalid
```

## Steps

1. Open the failed payout batch and read the bank's rejection reason for each failed payee. Expected: the specific validation failure is named (bad account number, bad routing number, closed account).
2. Ask the affected employee to re-enter their banking details carefully in the expense tool's payout settings. Expected: the details are corrected at the source.
3. Verify the format: correct routing number length, no spaces or dashes where the form forbids them. Expected: the details pass the tool's own validation.
4. Re-run the payout for the failed items. Expected: the payout processes and the batch shows paid.
5. Confirm receipt with the employee before closing the batch. Expected: the money arrived.

## When to use

- A reimbursement payout fails with invalid bank details.
- One or a few payees fail while the rest of the batch succeeds.

## When not to use

- The payout is blocked because expenses are not approved yet (approve first).
- The whole batch fails (check the payout account funding and connection).

## Tool compatibility

- Expensify, Ramp, Brex, and tools with direct reimbursement payouts.

## Variant phrasings

### Payout rejected: invalid account

The bank-side phrasing of the same failure.

### Banking details failed validation

The form-level phrasing of the same problem.

## Why it happens

Payouts go through bank validation before money moves. Typos, closed accounts, and changed banks all fail validation, and the payout batch marks those items failed.
