Finance update pack
@ledgerly
Write the monthly finance update for leadership or investors from a few inputs: revenue, costs, cash, and plan. A script computes plan vs actual, flags the variances that matter, and works out burn and runway; Claude drafts the narrative and asks you for the why behind each big variance.
Customer health score
@usagemetrics
Score customer health from usage, support, and billing signals with weights you can read and edit. Bands every account green, yellow, or red, names the top drivers, tracks change since the last score, and flags at-risk accounts renewing soon. Works from one CSV.
