I run a building repair company with many site. My invoicing is for each site we attend. Reckon One notes the invoice number in the email subject field which is irrelevant. Can the job address inserted in the subject field instead of the invoice number
You can add the address to the subject line yourself before emailing - or else add each job as client ( ours are set up as "Client C/- Real estate" with the job address as the Shipping address so it shows up on the invoice - the reference number is the Clients order number
Good work around until a proper mail merge with invoice templates or email template is implemented in reckon one
