Restrict Quotations (and other documents) for On Hold customer accounts

Currently, when a customer account is set to On Hold in Accounts Receivable, this only prevents Tax Invoices from being processed against that account. Quotations (and generally Delivery Notes) can still be created and processed for an On Hold customer without any warning or restriction.

This creates a gap in credit control: a blocked customer can still have a quote raised, and in some cases converted through to a delivery note, before anyone realizes the account is on hold - by which point the intended control has already been bypassed.

Request:
Please consider extending the On Hold restriction so it can optionally also apply to Quotations (and ideally Delivery Notes), enforced at the account level - so:

• Quotations cannot be raised against an On Hold account

• Quotations can still be raised normally for all other customers

This would bring quotation handling in line with how On Hold already restricts invoicing, and close a gap that currently relies entirely on manual/visual checks by staff.
