The problem with either autocomplete or a dropdown combo is that it makes it really easy for a user to mistype the customer name and add the same customer multiple times. While there's no perfect way to handle that situation, I might use a dropdown list where:

> - the top item is "New customer"; when the user chooses that item, I'd pop up a form for the user to create the new customer. In that form, after the user enters the customer name, I'd do some kind of fuzzy search and if there are matches, ask the user to confirm they don't mean one of those customers. Fuzzy search (like with Soundex()) is imperfect, but would catch a lot of the duplicates.

Hi Tamar and thanks for your time. The customers will be already registered in the database. So, no need to add "new" option or something like that. I tried before entering data with a textbox Autocomplete ON and liked how easy to find and enter the right values, I never used a combobox like "dropdown combo" but I guess it would me more complex for the user to use it.
