Common questions

FAQ

Does InvoiceXO work with desktop Outlook?
Yes — InvoiceXO works in OWA (browser), desktop Outlook (Win32), and New Outlook. Mobile Outlook requires admin deployment via Microsoft 365 Admin Center.
Where are my invoices saved in OneDrive?
Invoices are saved to a folder called InvoiceXO in the root of your OneDrive. You can change the folder name in the Save Settings panel inside the add-in.
What file types does InvoiceXO support?
InvoiceXO currently supports PDF invoices. Word (.docx) and Excel (.xlsx) invoice support is coming soon.
How does the fraud detection work?
InvoiceXO automatically checks every invoice email for common fraud signals: display name mismatches, reply-to domain mismatches, newly registered sender domains, parked/for-sale domains, and suspicious redirect links. Warnings appear at the top of the taskpane before you process the invoice.
Can I customise the file naming convention?
Yes — use the token builder in the Save Settings panel to create your own pattern. Available tokens: {vendor}, {invoice}, {po}, {amount}, {due}, {date}. Example: {vendor}_{po}_{amount}_{due}.pdf
Is my invoice data stored on your servers?
Invoice PDFs are processed through our API (using Claude AI for extraction) but are never stored on our servers. Files are saved directly to your OneDrive.
What is PhishGuard and how does it protect me?
InvoiceXO includes PhishGuard fraud detection built in. Every invoice email is automatically scanned for spoofed sender domains, display name mismatches, reply-to fraud, newly registered domains, parked/for-sale domains, and suspicious redirect links — before you process any payment. No setup required.
What happens when my trial ends?
You'll receive an email reminder before your trial expires. After expiry, invoice extraction and OneDrive save are paused until you subscribe. Your OneDrive files are never deleted.
