Word 2007 Template

I have created a template in Word 2007 which picks up details from my customer database and creates an invoice for each job I do.
I used mail merge to do this although I do not want to print or email in batches.
My problem is that when I save the document under the customer's name in my invoices folder, all the data source information is saved as well, so when I open the file again I am prompted to agree to the data being read from my database, this obviously means that if I email the invoice to the client it will not display the information because he has no access to my database.
So I would like to know how to save the document as a stand alone word file that just the actual information on the screen.
Anyone?
