CBA Laboratory Exercise
The new proposed automated cashiering and inventory system of G-Mall requires php 500,000 development cost. The determined economic life of the new system will be 5 years. Once the development is finished, the company will need to spend php 100, 000 for the employees training. The personnel salaries are estimated to php 500,000 per annum. The software lease (including license fee) will cost php100, 000 per year. In-house maintenance during operation will incur php 50,000.
