There is more context, please help 12:49 Aug 3, 2011
What is the nature of the good listed in the invoice?
Are there any headings?
What activity sector is involved? (is it really an invoice for items used in "Marketing / Market Research"??)
Please supply two or theree other items, so somebody can figure it out.
Please help us help you, thanks.
