Within Teamwork CRM, you can create companies to manage who you are trying to sell to.
To add a new company to your site, select Companies from the People dropdown at the top of your site.
Click the Add company button in the top right of the Companies area.
In the add company modal, you can add the company's name, email, website, address, phone and phone extension number.
You can also select a user from your site to associate with the company as an owner, and add an image for the company.
You can also create custom fields for companies in the Customize forms section of your site settings, depending on the information you want to include. When enabled, these fields will be included when creating a new contact.
