Modules
01 · Event inventory
Catalog renewals, trials, pauses, credits, refunds, and plan swaps in a shared taxonomy.

Connect invoice timestamps to deferred revenue schedules and catch silent offsets.
03 · Proration & credits
Rebuild proration math from logs; flag credit memos missing event IDs.

FAQ
Do I need a specific billing vendor?
No. Exercises use redacted CSVs and JSON samples that resemble common export shapes. You adapt the patterns to your stack.
Is this a replacement for a formal audit engagement?
No—and that is a real limitation. Cloudbasedops teaches assurance habits and documentation craft. It does not issue attestations or replace licensed audit opinions.
How much time each week?
Plan for five to seven focused hours, including one live office hour when you join Assurance Studio.
Reviews for this course
“Module 03’s proration rebuild saved our team from a recurring dispute with sales ops.”
Short take: clear rubrics. Longer note: the evidence pack studio is demanding if your exports are incomplete—bring raw files early.
