## ReChive

### description
ReChive is a communication-based document management system. ReChive stores documents in entries, where each entry represents a communication such as an invoice sent or a contract received.

### Key Features
- **Structured Entries:** Files are associated with metadata(such as Type, Sender, Date, Tags, and Amount) and represent a document sent or received.
- **Workspaces:** Each user can own or be a member of multiple workspaces, which are isolated environments for separating the documents of different entities. e.g., a personal workspace, a workspace for company 1 and a separate workpsace for company 2. This is specially useful for people who own/operate multiple companies.
- **Document Scanner:** Native mobile scanning with automated PDF conversion to digitize paper documents
- **Strict Auditable Mode:** A strict mode where all the documents are immutable and data are logged and traced for compliance purposes such GoBD for German businesses
- **Deadline Tracking:** Tracking the deadline/due date of the documents with email and native mobile notifications
- **Custom Reminders:** Providing the users with the ability to create custom reminders for entries
- **Integrated Sharing:** Creating pre-defined share targets, selecting the type of documents that needs to be shared, and be reminded with a document is not yet shared.
- **Granular Permissions:** You have a lot of control on the permissions and the access of the members of your workspace, allowing you to control what they see and are able to do

### Targeted Use Cases (Problem/Solution)
- **Payable and Receivable invoices:** Track the unpaid invoices and receive reminders to make sure you pay every bill on time
- **Business archiving:** Archive every document your business sends or receives, allowing you to find any document in a matter of seconds
- **Sharing financial documents with accountant:** Businesses would need to send all of their financial documents with to their accountant for bookkeeping. You can save your accountant as a share target, share the documents right within the app, and have an overview of which documents have been shared and which ones are yet to be shared. This is an alternative to emailing PDF files to your accountant.
- **Multi-person collaboration workflow:** An intern can enter the documents, the management can approve the document, and the person in charge of the payments mark the invoice as paid
- **GoBD compliance for German businesses:** By activating the "strict auditable mode", you will be prevented from deleting your documents (as you are required to maintain them for 10 years), guaranteeing your files are unaltered, and provide you with an audit portal upon request

### Technical Specifications
- **Privacy:** European-hosted data in compliance with GDPR
- **Social Authentication:** Google and Apple Authentication on all platforms.
