💡 Accountant's Note
SIM cards are inventory items expensed when distributed to subscribers or dealers. The cost is typically very low (JOD 0.50-2 per card) but volume is high for large operators.
Practitioner & Systems Framework
💻 ERP Architecture
SIM card inventory is managed in the inventory module of the ERP with a unique item code. SIM cards are received against purchase orders and posted to the SIM inventory account. When SIMs are issued to dealers or activated by subscribers, the cost is expensed to COGS (cost of SIM card). The SIM management system tracks each SIM by its ICCID from manufacture through distribution, activation, and eventual deactivation. Periodic physical counts of SIM card warehouse stock are reconciled to the ERP inventory balance.
⚠️ Audit Flags
Auditors reconcile the SIM card inventory balance to the SIM management system's stock count and perform or observe a physical count. Test that unactivated SIMs held by dealers are correctly classified — dealer-held unactivated SIMs may remain in operator inventory or be treated as delivered (depending on the distribution agreement). Confirm that eSIM issuance is correctly excluded from physical SIM inventory. Test for SIM cloning or fraud by reviewing anomalous activation patterns.
📄 Required Documentation
SIM purchase orders and invoices, inventory receipt records, SIM management system stock report (by ICCID status), physical inventory count, dealer-held SIM reconciliation, COGS charge for activated SIMs, and eSIM issuance records.
