Engineered for enterprise security.

Connecting a corporate Microsoft 365 environment requires strict governance. SubDupes is designed to meet the rigorous standards of modern IT and Infosec teams.

Shared AP Mailboxes

Built for finance teams. Connect specific shared inboxes (like ap@company.com) rather than individual employee accounts for cleaner data ingestion.

Microsoft Graph API

We utilize the modern, secure Microsoft Graph API. No legacy IMAP connections. Strict scope limitations ensure we only read what is explicitly authorized.

Azure AD Compatible

Seamless integration with your existing Azure Active Directory policies, including conditional access and MFA requirements.

Strict Data Isolation

Enterprise data is logically isolated. Personal email content is never read, stored, or used for any AI model training purposes.

SubDupes Dashboard

Clean, actionable data

Unlock data trapped in PDFs.

Most enterprise SaaS spend is hidden inside attached PDF invoices. Our Outlook integration doesn't just read email subjects; it intelligently parses the complex attachments that actually contain the financial data.

PDF Attachment Parsing

Enterprise vendors often send invoices as PDF attachments rather than text emails. SubDupes utilizes OCR and intelligent parsing to extract line items, seats, and costs directly from these attachments.

Automated Expense Matching

Once a PDF invoice is parsed, the engine automatically categorizes the vendor and matches the expense against your broader SaaS graph, instantly detecting if it's a duplicate or unmanaged purchase.

Continuous Extraction

Connect it once. Our engine runs continuously in the background, ensuring that the moment a new invoice hits the AP inbox, your optimization dashboard is updated.
