ComplianceNFs TODOs and Roadmap

TODOs in Codebase

ComplianceNFs.Infrastructure/Archiving/FileArchiver.cs

• FileArchiver.ArchiveAsync: Create subfolder for invoice.Status, move file

ComplianceNFs.Infrastructure/Mail/MailListener.cs

• MailListener.StartListening: Connect to mailbox, filter by allowlist, raise NewMailReceived

ComplianceNFs.Infrastructure/Parsers/PdfParser.cs

• PdfParser.Parse: Use iTextSharp or PdfSharp to extract text/numbers via regex

ComplianceNFs.Infrastructure/Parsers/XmlParser.cs

• XmlParser.Parse: Use System.Xml to parse known elements

ComplianceNFs.Infrastructure/Repositories/AccessDbRepository.cs

• AccessDbRepository.GetByUnidade: Implement actual query to Access DB

• AccessDbRepository.GetByUnidadeAndMonth: Implement actual query to Access DB

ComplianceNFs.Infrastructure/Repositories/AttachmentRepository.cs

• AttachmentRepository.SaveRawAsync: Implement actual insert into Postgres attachments table

• AttachmentRepository.UpdateMatchAsync: Implement actual update in Postgres

ComplianceNFs.Core/Application/Services

• InvoiceIngestionService: Implement ingestion logic and subscribe to NewMailReceived

• MatchingService: Implement invoice matching logic

• NotificationService: Implement notification logic for mismatches

• ArchivingService: Implement archiving logic for final status

ComplianceNFs.Monitor/MonitorViewModel.cs

• MonitorViewModel: Inject IInvoiceStatusStream and subscribe to updates

• MonitorViewModel.ForceScan: Call service to force ingestion cycle

ComplianceNFs.Service/Program.cs

• Register application services (InvoiceIngestionService, MatchingService, etc.)

Roadmap to Finish the App

1. Infrastructure Layer

• FileArchiver: Implement logic to create subfolders by InvoiceStatus and move files accordingly.
• MailListener: Use MailKit to connect to IMAP/Exchange, filter by allowlist, and raise NewMailReceived event.
• PdfParser: Integrate iTextSharp or PdfSharp, extract invoice data using regex.
• XmlParser: Use System.Xml to parse invoice XMLs and map to ParsedInvoice.
• AccessDbRepository: Implement queries to Access DB for buying records.
• AttachmentRepository: Implement Postgres insert/update for invoice attachments.

2. Application Layer

• Implement and register:

  • InvoiceIngestionService
  • MatchingService
  • ComplianceService
  • NotificationService
  • ArchivingService

• Wire up these services in DI in Program.cs.

3. Service Host

• Ensure all services are registered and started in the Worker.
• Implement polling and retry logic as per configuration.

4. WPF Monitor

• Inject and subscribe to IInvoiceStatusStream in MonitorViewModel.
• Implement ForceScan to trigger ingestion from UI.
• Bind UI to show recent invoice status updates.

5. Configuration & Testing

• Test all configuration values from appsettings.json.
• Add error handling, logging, and validation.
• Write integration tests for end-to-end flow.

Tip:

• Tackle infrastructure TODOs first, then application services, then UI and orchestration.
• Use comments in code for any business logic or mapping details that need clarification.
