How do I track SaaS spend across the company?
Combine three sources: your corporate card system for vendor invoices, your identity provider for OAuth-connected apps, and a per-tool admin export for seat counts — no single source has the whole picture.

Corporate card and expense tools (Ramp, Brex, Airbase, Bill.com) capture what you paid. Identity provider OAuth data captures what your people signed into. Admin exports capture how many seats each vendor is billing for.
The union of the three is your real SaaS surface. Companies that only use one source undercount by 30–60%.
Once you have the merged inventory, monthly delta reports catch new tools within days of the first invoice — the fastest way to notice shadow IT before it accumulates.
Automate this with SeatMap.AI
The audit path above works. It also takes hours per month per tool. SeatMap.AI runs it on a schedule, stages the reclaim actions for review, and shows you the annualized savings in real dollars.
