Why should you have to change to a PDF file i had no problems but recently i have had invoices that had no problem  going now being bounced, previously i have invoices that show as sent but were not received  i now realise probly ended up in spam, my other bugbear is if someone is in the database and you try to enter a the same name but differant address, doesnt like it probly the worst invoicing software i have used for invoicing  i used easy invoicing for years never an issue with bouncing emails and people with the same name only downside was no bank reconcilation, but as a one of payment thinking of going back  might be more work but the time im chasing trying to find out if someone has got it or not is so frustrating as a one man band i need cashflow and less hassle.
