Hi Matthew,

Thanks for using Sage City.

You can despatch the stock but say "No" to creating the invoice, so you can print a despatch note but an invoice is not created and the stock is not adjusted out. When you want to create the invoice you can choose despatch again but this time "yes" to the invoice and you can then invoice the entire order in one.

This doesn't work because when you next despatch an item on that SOP, the previously despatched items also show on the this second delivery note. I'm trying to find a way that sage knows the item is despatched (not allocated), and is therefore marked as despatched and as such so wont appear on subsequent delivery notes, and then I can create an invoice at the month end for any items despatched, but not invoiced. 
Or, is there a way to combine invoices?

Hi Matthew, thanks for coming back, I'm sorry that doesn't fulfil what you need. Unfortunately, there isn't current functionality to allow invoice to be combined in Sage 50 Accounts, it's certainly something you could add to the product Ideas Board though for possible future development: Ideas Board >

I'll leave this thread open in case any members of the community have alternative suggestions.
