I am looking at building a subscription based CRM for a specific niche, some customers will just be sole users and others will have multiple users under one business. How would i go about setting up my databases to achieve this. Would i need to just use specific conditions on every block though out the app or am i able to juts make settings for each user that they will only ever be shown their businesses data, as it would be a massive issue if multiple users were seeing each others data.
Thanks in advance for any help I appreciate it
