StackAudit
Upload your bank statement or billing emails. AI finds every SaaS subscription, kills the redundancies, and shows you exactly how much you're wasting.
The Idea
The average SMB pays for 40+ SaaS tools. Gartner says 25-30% of those licenses go completely unused. Finance teams find out at budget review time — usually too late. StackAudit lets any business owner or ops lead upload a bank statement PDF or forward their billing emails, then get back a complete map of every active subscription: what it costs, what category it falls into, which tools overlap with each other, and a ranked list of cuts with projected annual savings. Think of it as a one-time financial health check for your software stack.
Why Now
SaaS spending exploded 2020-2023 when remote work made "just add a tool" the default. Now the economic hangover is real. CFOs are doing SaaS rationalization exercises at every company from 5-person startups to 500-person scale-ups. "Software cost optimization" was the #1 IT priority in Gartner's 2025 CIO survey. And yet the only tools that exist are enterprise-grade spend management platforms (Zylo, Torii, Productiv) that cost $50k+ per year and require 6-month implementations. SMBs have nothing. The window is wide open.
How to Build
Two input paths: (1) PDF bank statement upload — parse with Claude to extract subscription charges by vendor, amount, and frequency. (2) Email forwarding address — users forward billing emails, you extract the same data from receipts. Claude then categorises each tool (project management, design, comms, security, etc.), flags overlaps ("you're paying for Notion AND Confluence AND Basecamp"), pulls pricing data for cheaper alternatives, and generates a ranked savings report. Output: a clean dashboard + downloadable PDF they can hand to their CFO or accountant. Stack: Next.js, Vercel, Stripe, Claude API.
Revenue Model
One-time audit: $49 per company (covers one full analysis + report). Pro: $29/month for continuous monitoring — new subscriptions flagged automatically, monthly savings report, price increase alerts. Team: $79/month with multi-seat access and integrations (Xero, QuickBooks). The one-time model is low friction for acquisition; the monitoring subscription is where retention and MRR live. Even 200 Pro subscribers = $5,800 MRR.
Effort
1 week for a solid v1. Day 1-2: PDF parsing + Claude extraction pipeline. Day 3-4: categorisation logic + overlap detection. Day 5: report generation + Stripe checkout. The email forwarding path is V2 — start with PDF upload only. The edge cases (international charges, one-off vs recurring) are the complexity, not the core logic.
Risk
Privacy is the obvious concern — people are handing you bank statements. You need airtight data handling, clear deletion policies, and ideally a "we never store your raw data" architecture. The other risk: this is a one-time problem. Once someone's audited their stack and cleaned it up, they don't need you again for 12 months. The subscription monitoring tier is what turns a one-shot tool into a durable business — invest in making that compelling from day one.
Genuinely underserved market with proven willingness to pay. The enterprise tools cost $50k/year — a $49 one-time audit is a no-brainer for any SMB owner who suspects they're wasting money. Privacy concerns are manageable with the right architecture. The real play is converting one-time audits into the monitoring subscription. Build it, price it low, let the savings report do the selling.
