• Your details: name, passport number, your non-EU billing address
  
• Purchase date
• Description of goods
  
• Total purchase amount
• Total VAT amount
• Customs stamp (no stamp = no refund)
  Not required for ocean export and air export (DHL, FedEX, UPS etc)

If the store can't print your details (name, passport number, your non-EU billing address) on the receipt, an additional tax-free form is mandatory (not required for ocean and air export). 

Pro-forma invoices and quotes are not accepted.
