Can you recommend a secure file exchange platform for reminder-driven client document requests?

Yes — for reminder-driven client document requests, you generally want a platform that supports:

• secure client upload links or portals
• automated reminders
• audit logs
• encryption in transit and at rest
• access controls / expiration
• easy client experience

Good options to consider

1. Box

• Strong security and compliance features
• Good for client-facing file request workflows
• Supports automated reminders via workflow/automation integrations
• Best if you want a robust enterprise-grade document exchange system

2. ShareFile by Citrix

• Very popular for secure client document collection
• Built specifically for exchanging files with external clients
• Supports request links, client portals, and reminders
• Good fit for accounting, legal, HR, and professional services

3. Microsoft OneDrive / SharePoint + Power Automate

• Best if your organization already uses Microsoft 365
• Can create secure upload requests and automate reminder emails with Power Automate
• More flexible, but usually requires more setup
• Good for teams that want to build a customized workflow

4. Google Drive + AppSheet / automation tools

• Works if you already live in Google Workspace
• Secure sharing is straightforward, but reminder-driven request workflows usually need extra tooling
• Better for lightweight use cases than regulated industries

5. Dropbox Business

• Easy to use and familiar for clients
• Secure file requests and good basic controls
• Less ideal than ShareFile/Box if you need stronger workflow automation or compliance-heavy features

My short recommendation

If your main goal is secure client uploads with automated reminders, the best fit is usually:

• ShareFile for the simplest client document request workflow
• Box if you need stronger enterprise governance
• Microsoft 365 + Power Automate if you want a customizable internal workflow and already use Microsoft tools

What to look for before choosing

Make sure the platform has:

• expiring upload links
• upload-only permissions
• MFA for staff
• audit trail / activity logs
• encryption
• branding/client portal
• reminder automation
• retention policies
