A connected accounting system posts approved operational documents into balanced entries while keeping the source relationship visible.
Use one posting engine
Sales, purchases, receipts, payments and payroll should use the same double-entry rules and period controls.
Protect posted history
Corrections should create linked reversals with an accounting date and reason. The original entry remains part of the audit trail.
Reconcile reports to lines
Trial balance, profit and loss and balance sheet should aggregate posted journal lines rather than dashboard summaries.
