I would like to create the invoice printing website.
I have three differnet content types
Product Customer Invoice Quotations
i had tried the node reference and relation module to fetch some of the data in invoice content type. but not succeeded.
i need the list of Customers and Products list to select into invoice content type. it seems difficult for me to create that.
Kindly help me to do the same and print my first invoice.
Please let me know the modules and procedure to create the same. Currently using drupal 7 for the task
