## If something is not working

<AccordionGroup>
  <Accordion title="Slash commands aren't showing up">
    Command registration isn't automatic on every restart for this bot. Ask whoever operates
    your Invoice Bot instance to run the owner-only `/sync` command — a global sync can take up
    to an hour to fully propagate to every server. If this instance is set up to sync only to a
    specific server for testing, commands will only appear there.
  </Accordion>

  <Accordion title="&#x22;Payment method unavailable&#x22; when attaching a method to an invoice">
    That provider isn't configured for this server yet. Check
    [`/payment_config`](/invoice/commands/admin) and make sure the relevant field (`btc_address`,
    `paypal_email`, etc.) is set — see [Configuration](/invoice/configuration) for the full list.
  </Accordion>

  <Accordion title="Verification says &#x22;underpaid&#x22; or &#x22;overpaid&#x22;">
    This is deliberate, not a bug — the transaction's amount to the configured address didn't
    exactly match the quoted crypto amount. Underpaid leaves the invoice unpaid so you can follow
    up with the customer; overpaid still completes the invoice and records the excess. Check the
    expected vs. actual amounts shown in the response.
  </Accordion>

  <Accordion title="&#x22;This transaction has already been used to pay a different invoice&#x22;">
    A given blockchain transaction hash can only ever complete one invoice per asset. If you
    believe this is wrong, check which invoice actually claimed it with
    [`/crypto_lookup`](/invoice/commands/crypto) before assuming it's an error.
  </Accordion>

  <Accordion title="A crypto quote expired before the customer paid">
    Quoted crypto amounts are only valid for a limited window. Run
    [`/invoice payment`](/invoice/commands/invoices) again with the same method (or use the
    **Refresh Quote** button on the invoice's payment panel) to issue a fresh quote and amount.
  </Accordion>

  <Accordion title="No PDF export or QR code showing up">
    Both are optional features that may or may not be enabled on the particular bot instance
    you're using. If **Export PDF** or a crypto payment's QR code isn't appearing, the rest of
    the invoice still works fully — ask whoever operates your instance whether that optional
    feature is turned on.
  </Accordion>

  <Accordion title="Can't delete an invoice">
    Only invoices currently in **Draft** or **Void** can be deleted. Void it first with
    [`/invoice void`](/invoice/commands/invoices) if it's in any other status — see
    [Invoice lifecycle](/invoice/features/lifecycle).
  </Accordion>

## Getting help

There's no publicly documented Discord support server or contact address for Invoice Bot in the
materials this documentation is built from. If something here doesn't cover your situation,
contact whoever operates your Invoice Bot instance for your server — they're the ones who can
look at the running bot directly.

When reporting a problem, it helps to include:

* The exact command you ran and what happened instead
* The invoice number involved, if any
* Whether the issue is specific to one payment method or affects everything
