Email Vendor Remittance Payment & Inventory Default account number

SUGGESTED

Is there a way to email to the vendor a copy of their payment.  I make a payment on a vendor and they want a copy of it.  Currently I print it and fax it to them.  Would be easier to just email it.  Is there a flag I need to change to allow this.

Inventory items.  All inventory items create go to the same accounts  #1300 Inventory and 5005 Cogs.  Is there a way to link these accounts instead of entering them each time.

Thanks
