Enterprise-grade invoice detection.
Built for finance teams and shared AP mailboxes. One Outlook rule forwards every software invoice to SubDupes, which extracts the spend data automatically — including from PDF attachments. No mailbox connection required.
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. Put the rule on a shared inbox such as ap@company.com rather than individual employee accounts, and the data stays clean at the source.
Nothing To Authorize
No Graph API scopes, no IMAP credentials, no app registration to approve. The rule lives in Outlook and forwards messages outward, so there is no inbound access to grant.
Azure AD Compatible
Nothing to exempt from conditional access or MFA, because SubDupes never authenticates against your directory. Your existing Azure AD policies are untouched.
Strict Data Isolation
Enterprise data is logically isolated. Personal email content is never read, stored, or used for any AI model training purposes.
How the Data Flows
Microsoft Outlook
Raw connection
Receipt Detection
Financial filters applied
Metadata Extraction
Cost, dates, seats parsed
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
Set the rule once. From then on, the moment a new invoice reaches the AP inbox it is forwarded and parsed, and your optimization dashboard updates on its own.
Seats: 125
Seats: 80
One rule in Microsoft 365.
Stop relying on manual spreadsheets. Point one Outlook rule at your SubDupes address and your software spend assembles itself — no Graph API connection, no mailbox permissions.
