Zendesk's most affordable option is limited to three seats. To accommodate larger teams, you must move to the Professional edition for US$ 49/user/month. This may price out some small businesses. Many desirable features, such as task automation and multiple pipelines, are only available at the Enterprise level, which is US$ 99/user/month.  Also, if you also want customer support, that is a separate Zendesk subscription beginning at US$ 49/month/user. Businesses may want to consider competitors, such as Pipedrive, that offer a similar feature set without the same limitations on users, pipelines, and workflows.
