## TL;DR

The invoice's approval did not complete: an approver step failed, timed out, or was misconfigured. Find the failed step in the invoice's approval history, fix the underlying cause (approver access, amounts, coding), and re-trigger approval.

## Error

```text
Spendesk: invoice approval failed
```

## Steps

1. Open the invoice in Spendesk and view its approval history. Expected: the failed step is named with a reason.
2. If the step names an approver who cannot act (deactivated, on leave), ask your Spendesk admin to reassign it. Expected: the step points at an active approver.
3. If the failure is about coding (cost center, category), correct the invoice coding first. Expected: the invoice validates cleanly.
4. Re-trigger the approval from the invoice actions. Expected: the invoice routes through the fixed chain.
5. For recurring supplier invoices, set up a standing approval flow. Expected: future invoices from that supplier route automatically.

## When to use

- A Spendesk invoice shows approval failed rather than approved or rejected.
- The invoice is valid and should have been approvable.

## When not to use

- An approver rejected the invoice on its merits (resolve the objection).
- The invoice data itself is wrong (correct with the supplier first).

## Tool compatibility

- Spendesk invoice management; admin access needed to reassign approval steps.

## Variant phrasings

### Invoice could not be approved

Same failure, alternate wording.

### Approval workflow error on invoice

The configuration-flavored phrasing of the same problem.

## Why it happens

Invoice approvals depend on the approval chain, the invoice coding, and approver availability. A break in any of the three fails the approval instead of completing it.
