Automated Debit Order System with Client Verification

I need a secure and automated debit order system tailored for my business to streamline payment collections. The system should ensure payments are processed only for clients who have physically signed proper documentation at our business location. Key features include:
- Client Verification: A secure feature to upload and store signed client documents for authorization.
- Automated Debit Orders: Recurring payments processed automatically without requiring further client authorization after verification.
- Failed Payment Management: Notifications for failed payments, with options to retry or flag them for manual follow-up.
- Secure Database: A platform to manage client records, payment schedules, and signed agreements securely.

The system must be reliable, user-friendly, and completed within 4 to 5 days.
