CapEx: Capital Expenditure
Refers to the funds a business spends to acquire, upgrade, or maintain physical assets such as property, buildings, equipment, or technology. These investments are typically significant and made to enhance or extend the organization's ability to generate revenue over the long term. In the telecom industry, CapEx often includes purchasing network infrastructure, communication hardware, and other long-term assets. Unlike operating expenses (OpEx), which cover day-to-day costs, CapEx is recorded as a long-term investment on a company’s balance sheet and is subject to depreciation over time.
OpEx: Operating Expenditure
Refers to the ongoing costs a business incurs for its day-to-day operations. These expenses are short-term and typically include salaries, utilities, rent, maintenance, and subscription-based services like software or HWaaS. In telecom, OpEx may cover costs for network maintenance, telecom carrier services, or leased communication equipment. Unlike capital expenditures (CapEx), OpEx is fully deductible in the same financial year, providing more flexibility in managing cash flow.
