What it does

Produces the finance team's month-end SaaS spend variance brief without anyone exporting CSVs by hand. It reconciles what was actually charged to company cards in Stripe against the budgeted subscription roster in Snowflake, then highlights every vendor whose spend moved materially versus the prior month.

When to use it

Run it on the first business day of each month to close the books on software spend. It replaces the manual pivot table the FP&A analyst rebuilds every cycle and surfaces surprise renewals, seat creep, and silent price increases before they hit the P&L review.

How it works

  1. 1A monthly schedule fires on the first business day.
  2. 2It pulls the prior month's card charges from Stripe, grouped by merchant.
  3. 3It queries the canonical subscription roster and last month's actuals from Snowflake.
  4. 4A logic step joins both sets per vendor and computes dollar and percent variance.
  5. 5Vendors crossing a variance threshold are flagged as over, under, or new.
  6. 6The ranked brief is posted to the finance Slack channel with the top movers called out first.
