HiddenBill

HiddenBill is a SaaS spend discovery tool that scans your Gmail inbox for billing emails — receipts, invoices, and renewal notices — to surface every tool your company is paying for. It connects via read-only Gmail access in under two minutes and produces a clean report of subscriptions, charges, renewals, and likely forgotten software.

Key Features

• Email-based discovery: Scans for SaaS billing signals, signup emails, and renewal warnings without requiring integrations or IT approval.
• OCR receipt parsing: Pulls SKUs, totals, due dates, and messy receipt details from photos and forwarded receipts.
• Accounts vs. billing gap: Shows the difference between tools you signed up for and tools actually billing you.
• Read-only by design: Cannot send, delete, or modify emails. Google enforces this at the API level. OAuth verified by Google in December 2025.

Use Cases

• First-pass SaaS audit for founders and lean teams without a finance department.
• Catching forgotten subscriptions, duplicate tools, and upcoming renewals before they charge.
• Tracking AI tool spend, token invoices, and trial conversions in one place.

Who It's For

• Founders, CTOs, CFOs, and small teams who need a fast software spend view before committing to an enterprise SaaS management platform.
