Subscription metrics live in Zuora. The GL lives in NetSuite. Revenue rec lives in Excel. That's three sources of truth and the monthly close becomes a reconciliation exercise. Mid-cycle plan changes break the billing system every release. Deferred revenue is a manual calc that the auditors hate. ASC 606 wants evidence per contract — Finance has evidence per spreadsheet.
Pre-built Q2C workflow tuned for SaaS: CPQ → contract with performance obligations captured at the line level → e-invoice → subscription billing with mid-cycle proration and usage metering → cash application at the line → revenue recognition under ASC 606 / IFRS 15 → journal entries posted in real time across every entity. One operating brain (Astral) holds the subscription, contract, and revenue-rec state. The ERP and billing system both read from it.
