Dropbox is pure storage. There is no concept of "order", of "work item status", of "request form". Such layers must be constructed separately with Zapier or custom automations, or are simply absent and reliance is placed upon WhatsApp.
CadCamCloud proceeds from the order: each submission is a job, each file within it is a job_item with its own status (received, in production, quality control, ready, shipped). The practice views the status in real time without the need for telephone calls. REST API + signed webhooks to integrate the lab management system natively, rather than via fragile bridges.
