  This guide is being written. The topics below show what it will cover.
</Note>

## Planned topics

* Edit invoice settings for payment instructions and payment details.
* Choose whether invoices include a client portal QR code and review the preview.
* Add or edit notes for one job invoice and distinguish them from shop-wide settings.
* Link tax and processing-fee changes to pricing/payment documentation rather than repeating those guides.
* Explain which changes apply to future documents and which depend on the invoice source.
