Flag off-pattern card charges against department budget envelopes
Watches new Stripe card charges in real time, compares each one against the spending department's monthly budget envelope and trailing 90-day pattern in Snowflake.

What it does
This workflow turns every Stripe card transaction into a live budget check. When a charge posts, it looks up which department the card belongs to, pulls that department's monthly envelope and trailing 90-day spend baseline from Snowflake, and decides whether the charge is on-pattern or an outlier. Only the outliers reach a human.
When to use it
Run this when finance wants to catch overspend the day it happens instead of at month-end close. It is built for teams that issue cards by department and track budgets as fixed monthly envelopes, and that already land transaction history in Snowflake.
How it works
- 1A Stripe webhook fires on each new card charge.
- 2The workflow queries Snowflake for the card's department, its current-month envelope, and the trailing 90-day median and standard deviation for that merchant category.
- 3A logic step flags the charge if it pushes month-to-date spend past the envelope or sits more than three standard deviations above the category baseline.
- 4On-pattern charges are logged silently to Snowflake.
- 5Flagged charges post to the finance Slack channel with the amount, department, envelope headroom, and the specific rule that tripped.
