Fees and finance

Recording a payment generates a numbered receipt, files it to the parent's Memory Locker with a verification code, and notifies them. Fee ageing, collection rate and payroll all read the same rows, so they cannot disagree.

• ✓Fee ledger with live collection and ageing buckets
• ✓Receipts with a public verification code anyone can check
• ✓Payroll banded to EDGE grade — a paid payslip is never overwritten
• ✓Reports computed at page load, never cached
