We use an external mail merge software to send large amounts of multi-product invoices to customers - primarily because we can fold all the product lines up into a single price from Excel and then have a custom Service Detail summary that appears on each invoice.

This is unnecessary in my eyes and adds more admin to the process as we have to then import this data to Sage.

If we had the ability to check an option, either on the invoice window itself, or in settings (so when I do batch product imports to Sage I dont have to change every single one!)  that meant that a Message Line on our invoices would be displayed in the Details field - we could start invoicing in batch through Sage and enjoy the SagePay/Pay Now features.

Furthermore, this absolutely needs to be be present in the Sage Report Designer, so when I am generating Statements and Late Payment letters, the details field is actually descriptive, rather than the current generic 'Goods/Services' text that appears with the 'STMT_TEXT' data field.

We need to have the option for Message lines on invoices to appear in the details!
