The contact information screen is the place to go when you need to update any information about a client. It is the screen that will appear when you choose to enter a new client, or edit an existing client.
As you enter the different values here, you can use the [Tab] key on your keyboard to move from one field to the next more efficiently.
The Commercial checkbox should be checked if the client is a company, and then you will be able to enter the Company Name in the box provided.
The Title box allows you to choose a title or salutation for the customer that will usually be used when you create mail merge letters for the client. You can choose from any of the choices in the drop-down box, or just type whatever you want as the title.
The First and Last Name boxes are for the main person you deal with for this contact. If this is not a commercial entry, then it will just be the name of the client. Notice that there are options to make these entries be proper case on the Company Setup screen.
