<section class="help-summary" aria-labelledby="in-short"><h2 id="in-short">In short</h2><p>Data can come from Pennylane, Zoho Books, API, or manual entry. An invoice or credit-note issue channel is fixed at creation, while the account separately keeps its connection reference. A manual invoice can therefore live on a synchronized account. Correct each record in its originating system to avoid later reversions.</p></section>

## Expected result

You identify account source and document channel before any edit or deletion.

## Before you start

- Open both the account and affected document detail.
- Keep source-tool access when the record is synchronized.

## Procedure

1. Locate the account source badge and latest update.
2. On the invoice or credit note, check Pennylane, Zoho Books, API, or Manual channel.
3. Correct integration-managed fields in the source.
4. Use Billabex directly only for manual data or an explicitly local action.
5. After synchronization, verify the correction appears without duplication.

## What Billabex does

The source reference links an account to a connector, while each document channel remains independent and immutable. This allows occasional local entry without hiding account origin.

## If the result is not what you expected

- A local edit to synchronized data can be overwritten on the next run.
- Do not recreate a missing document manually before checking the connection.
- For duplicates, compare normalized references, channels, and source identifiers before deletion.
