💡 Accountant's Note
Large SaaS companies pay upfront for 'Reserved Instances' to save money. This entry moves 1/12th of that cost to the monthly P&L.
Practitioner & Systems Framework
💻 ERP Architecture
Track each Reserved Instance commitment in the prepaid schedule with the instance type, region, term (1-year or 3-year), upfront cost, and monthly release amount. Configure auto-journal entries to release monthly. Reconcile the total prepaid RI balance in the ERP to the AWS Cost Explorer 'Upfront Reserved Instance' report at each quarter-end.
⚠️ Audit Flags
Auditors verify that the amortization period matches the actual reservation term — 1-year RIs should be fully amortized in 12 months, 3-year RIs in 36. They also check whether RIs that were cancelled or modified have been adjusted accordingly. Classification (Cost of Revenue vs. R&D) must follow the underlying instance use.
📄 Required Documentation
