More options for email and cost centres

This extension combines email handling with clear internal allocation of quotes and invoices.

• Connect additional compatible providers using IMAP/SMTP; test incoming and outgoing email separately.
• Edit, disconnect or remove connections.
• Company admins create and manage cost centres and allocate quotes and invoices internally.
• New invoices inherit an existing cost centre from the quote. Filter invoices by cost centre and analyse them in the invoice Excel export.
• Enter cost centres manually or import lists with a preview where enabled by the plan.
• Remove staff access while preserving business history and author references.

Cost centres do not appear on the customer PDF. Check supported import formats and activation. This is not a full accounting system, bank reconciliation or tax certification.
