Inbox Invoice Intercept
Scan inbound email for invoices, extract key signals, and stop fraud early—before AP ever sees it.
Fraud targets humans—not systems
Attackers know that AP departments have controls. So they don't send fraudulent invoices to AP.
They send them to executive assistants, regional managers, department heads—anyone who might forward an invoice without scrutiny. By the time AP sees it, the social engineering has already worked.
The blind spot in traditional AP controls
Your AP team can verify every invoice they receive. But they can't verify invoices they never see—the ones that arrive in executive inboxes with a note saying "please pay this."
How Inbox Invoice Intercept works
Four steps to catch fraud before it reaches your AP team.
Detect invoice-like emails
TruePayables scans inbound emails for PDFs, keywords, and patterns that indicate invoices or payment requests—regardless of which mailbox receives them.
Extract vendor + payment details
We pull remit-to addresses, bank account information, invoice numbers, amounts, and vendor identifiers from detected invoices automatically.
Verify authenticity
Every invoice is checked against sender domain history, vendor master data, and historical invoice patterns. Discrepancies are flagged immediately.
Warn, quarantine, or route
Recipients see warning banners on suspicious emails. AP gets notified. Verified invoices can be automatically routed into your intake queue.
Payment instruction changes are always high risk
When banking or remittance information differs from the vendor master or historical invoices, we flag it as urgent and require verification before any payment can proceed.
- New bank account numbers
- Changed routing numbers
- Modified remit-to addresses
- ACH to wire transfer changes

Real-world scenarios
How Inbox Invoice Intercept protects your organization.
EA receives "urgent invoice"
An executive assistant gets an email with an attached invoice marked urgent. TruePayables instantly flags the suspicious domain and warns the recipient before any action is taken.
Vendor requests "updated ACH details"
A seemingly legitimate email asks to update banking information for an existing vendor. The change is detected and requires verification through a trusted channel.
Department inbox receives invoices
Invoices sent to a regional office or department mailbox are automatically detected, verified, and routed into the centralized AP intake queue.
Frequently asked questions
Does this read all my emails?
No. We only analyze emails that match invoice-like patterns (PDFs, specific keywords, payment-related content). Regular business communications are not scanned or stored.
What inboxes can we monitor?
You can monitor individual mailboxes, shared mailboxes (like ap@company.com), or distribution lists. Enterprise plans support organization-wide deployment with admin controls.
What happens when you're not sure it's an invoice?
Uncertain cases are flagged for human review rather than auto-processed. You can configure sensitivity thresholds based on your organization's risk tolerance.
Can we quarantine emails or just warn?
Both options are available. You can choose to display warning banners only, quarantine suspicious emails for review, or automatically route them to a holding queue. Configuration is per-mailbox or organization-wide.
How does this integrate with our AP workflow?
Verified invoices can be automatically created as intake items in your TruePayables queue, sent to a ticketing system, or forwarded to your ERP's invoice processing workflow. We support webhooks and direct integrations.
What permissions does the M365/Gmail integration require?
We request the minimum scopes needed: read access to mail (for scanning), and optionally write access (for warning banners and quarantine). Full permission details are provided during setup.
Can employees bypass the warnings?
Warning banners are informational—employees can still process emails. However, all actions are logged, and you can configure policies to require explicit acknowledgment before proceeding with flagged invoices.
