Automated payment fraud monitoring for construction and trades SMEs
Automatically detect risky invoice and payment emails before money leaves your business.
Sentra monitors selected invoice and payment-related mailboxes, flags potential payment fraud including fake invoices, supplier impersonation, and fraudulent bank-detail changes, then creates verification workflows before payment. Connect Xero and Microsoft 365, subscribe, and use Sentra in your finance workflow — we welcome feedback from customers as we continue to improve detection and controls.

The payment risks construction businesses face
Attackers do not need to break your whole business. They only need one fake invoice, one supplier impersonation, one fraudulent bank-detail change, or one diverted payment to cause serious loss.
Fake invoices
Payment details that do not match your verified supplier records.
Supplier impersonation
Emails that look like a known supplier but use different domains or reply addresses.
Fraudulent bank-detail changes
Requests to pay into a new account without independent verification.
Payment diversion
Urgent or compromised-email scams pushing payments before checks are completed.

Built for Microsoft 365 payment-risk workflows
Sentra focuses on payment-risk emails: invoices, bank-detail changes, supplier payment requests, and urgent payment instructions. Connect Microsoft 365, choose the mailboxes you want monitored (such as accounts@ or invoices@), sync suppliers from Xero, and let the overseer flag mismatches before you pay — without organisation-wide mailbox access.
