Accrual Guidelines
When to Accrue
Accrue if: - Goods or services received during the month - Invoice not yet received - Amount is reasonably estimable - Amount is material to your business
How to Estimate
| Item | Estimation Method |
|---|---|
| Utilities | Prior month average or budget |
| Professional services | Contract rate × hours, or budget |
| Inventory in transit | Shipping documents × PO price |
| Recurring services | Contract amount |
Accrual Entry
Debit: Expense Account Credit: Accrued Expenses (or AP-Accrued)
Next month: Reverse the accrual, then book actual invoice.

If material: - Book accrual for estimated amount - Document that invoice arrived late
