Structured inventory
The software receipt problem.
Without automation, tracking software spend is a manual, broken process that wastes hours of productive time every month.
Forwarding Invoices
Every time a subscription charges your card, you have to find the email, download the PDF, and manually forward it to your accounting software or finance team.
Manual Data Entry
Someone has to open a spreadsheet, type in the vendor name, the cost, the date, and attempt to guess when the next renewal will hit.
The Lost Details
Because it's manual, nobody logs the actual product name or the specific plan. You just see "Adobe" and have no idea if it's Photoshop or Acrobat.
Are you reading my emails?
Absolutely not.
SubDupes uses a Zero-Trust Read-Only API. Our automated system strictly filters your inbox for known software vendor domains (like @stripe.com or @adobe.com). It extracts the receipt data programmatically, and discards the rest.
Read-Only Access
We can never send, delete, or modify your emails. We only have permission to read.
No Human Access
No human ever reads your emails. The entire extraction process is 100% automated by code.
Exactly what SubDupes processes.
Our system is intentionally blind to anything that isn't a software transaction.
What We Ignore
- Personal conversations
- Emails from colleagues
- Attachments unrelated to receipts
- Legal documents
- Family photos
- Password resets
- Banking login information
What We Process
- Software receipts
- Subscription invoices
- Vendor billing notifications
- Renewal reminders
- Seat upgrade receipts
The source of truth isn't your bank.
It's your inbox.
When a software product is purchased, the most detailed, high-fidelity record of that transaction is always emailed to the buyer.
What's inside a receipt?
- The exact product name (not just the vendor)
- The number of seats or licenses
- The billing frequency (Monthly vs Annual)
- The specific renewal date
- Taxes and hidden fees
- The buyer's email address
"We realized we could bypass the slow, messy process of asking employees for invoices. The data was already sitting perfectly structured in their inboxes. We just needed an engine to extract it."
The SubDupes Insight
Why not just connect the bank?
Bank feeds show that money left your account. They don't show what you bought, who bought it, or when it renews.

How the API Sync works.
SubDupes utilizes native OAuth integrations with major providers to securely authenticate without ever seeing your password.
1. Secure OAuth Authentication
You authenticate directly with Google Workspace or Microsoft 365. SubDupes receives a secure token. We never see, touch, or store your email password.
2. Programmatic Filtering
Our system queries your inbox metadata (sender email addresses) against our database of 10,000+ known software vendors. If an email isn't from a software vendor, the system ignores it immediately.
3. Isolated Extraction
Only verified receipts are passed to the SubDupes extraction engine. The engine parses the text, structuring the raw data into clean JSON, and updates your inventory.
From raw inbox to structured data.
Watch how our engine processes an unstructured email and turns it into clean, analyzable JSON data.

SubDupes doesn't just guess. We maintain an active database of over 12,000 SaaS vendor email domains to guarantee precise identification.
12,400+ Software Vendors Indexed
When an email arrives from a known domain, the system immediately flags it for extraction. If an email is from johndoe@gmail.com, the system ignores it without ever attempting to read the contents.

Hidden Renewal Extraction
Software companies love to bury the auto-renewal date in the fine print of their invoices.
Our AI specifically hunts for phrases like "Next billing date," "Automatically renews on," and "Commitment term ends." It pulls that date out and injects it directly into your SubDupes renewal calendar.
...for choosing our annual Pro plan.

Real-time Duplicate Detection
When tracking manually, you rarely notice that Marketing bought Asana while Engineering bought Monday.com.
Because SubDupes scans the inboxes of multiple team members simultaneously, it instantly flags when overlapping tools are purchased, alerting you to immediately consolidate contracts.

Frequently Asked Questions
Common questions about how SubDupes discovers software.
SubDupes uses an automated, read-only OAuth connection to scan your inbox metadata. When it detects an email from a known software vendor (e.g., @adobe.com), it extracts the relevant receipt data such as the product name, cost, and renewal date. It never touches or reads personal emails.
Bank feeds only show that money left your account and often display obscure merchant names. Email receipts contain the actual 'source of truth'—the exact product, the tier, the number of seats, and critically, the next renewal date and invoice attachment.
Yes. SubDupes utilizes a zero-trust architecture. We use read-only API access without ever storing your passwords. All data is encrypted with AES-256 standards, and no human ever reads your emails.
Our extraction engine is backed by a continuously updated database of over 12,000 SaaS and software vendors, ensuring we capture everything from enterprise infrastructure (AWS) to design tools (Figma).
Less than 60 seconds. Because there are no agents to install or CSVs to upload, you simply connect your Google Workspace or Microsoft 365 account via OAuth, and the engine begins building your inventory instantly.
