Introduction

The point of sale (POS) is the time and place where a retail transaction is completed. At the point of sale, the merchant would calculate the amount owed by the customer and indicate the amount, and may prepare an invoice for the customer (which may be a cash register printout), and indicate the options for the customer to make payment. It is also the point at which a customer makes a payment to the merchant in exchange for goods or after provision of a service. After receiving payment, the merchant may issue a receipt for the transaction, which is usually printed, but is increasingly being dispensed with or sent electronically.

The point of sale is often referred to as the point of service because it is not just a point of sale but also a point of return or customer order. Additionally, current POS terminal software may include additional features to cater for different functionality, such as inventory management and financials.

Businesses are increasingly adopting POS systems and one of the most obvious and compelling reasons is that a POS system does away with the need for price tags. Selling prices are linked to the product code of an item when adding stock, so the cashier merely needs to scan this code to process a sale. If there is a price change, this can also be easily done through the inventory window. Other advantages include ability to implement various types of discounts, a loyalty scheme for customers and more efficient stock control.

Background Of The Study

Hardware is owned by Emma C. Yu. The business operation started 3months ago, it is specifically on September 15, 2016. Hardware is located at the Blk. 1 Lot 2 Escala Road, Brgy.

Review of Related Literature

This chapter includes a compilation of related topics and studies that are relevant to HARDWARE Point of Sale System.

Local Studies

  • Walmart Store

Walmart Stores feature a great selection of high-quality merchandise, friendly service and of course, Every Day Low Prices. Founded in January 2000. Walmart developed a point of sale, POS system that completely unifies the concept of supply and demand. In Walmart stores, when something is bought, it is registered in a cash register, which is also connected in a corporate purchasing headquarters. When a sale is made this means there is one fewer product of that type on the shelf. When the signal is received at the purchasing office that an item has been sold it immediately orders the purchase of another one for re- supply. In this way Walmart has reduced bureaucracy, as purchasing orders are done automatically relative to items being bought at the POS.

  • Calea POS

Calea POS system made their daily transactions fast and easy. Customers enjoy the doles of point of sales program as the system is a responsible for more customer-oriented services for any type of business. Their POS have staff management features such as sales tracking for each employee, commission totals, forecasted sales and top employee based on sales.

Foreign Studies

  • pcAmerica Point of Sale System

Grocery stores are usually the busiest types of businesses. It is hard to fight against the long lines of people who are itching to be checked out fast. Cash Register Express POS System has all the necessary ingredients to not only check out the customers quickly, but to track each item being sold. Even in a multi-user environment. Cash Register Express is known for its stability on the network.

Cash Register Express has been designed with a revolutionary technology for bulletproof network performance with its Enterprise edition. This special edition of Cash Register Express allows the server to go down while all stations remain working. When you get the server up and running again, the stations will synchronize all the data. You will not ever have to worry about your system going down.

A typical point of sale system for a grocery store should include a Dell small form factor computer, cash drawer, pole display, receipt printer and laser bar code scanner or  in counter scanner/weight scale. The pole display will inform your customers how much they are paying so they are likely to have the cash out quickly. A laser bar code scanner with built in scale aggressively scans bar codes that might be on bags or around bottles and quickly adds the item to the invoice as well as weighing item that need to be weighed. All these devices help to reduce the time it takes to process a customer and as any store owners knows, the faster you process your customers, the faster you make money.

The Developmental Cost table the total amount of the system. While the Operational Cost table features the sum of the company’s expenses in a year. The Benefit table displays the possible amount that the company 4may obtain if the system is going to be implemented. Since the company, Hardware , aquires an income of more than Php 400,000.00 each year.

The Benefit table displays the possible amount that the company may obtain if the system is going to be implemented. Since the company, Hardware acquires an income of more than Php 3,000,000.00 each year. It is presumed that it would at least gain an additional Php 393,000.00 if the system is implemented.

Cost Benefit Analysis

Figure 5 shows a chart of the cost and benefit analysis. The payback period came out as 1.26. the proponents divided the company’s initial investment to the presumed Php 393,000.00 benefit that the company and multiplied the quotient of 12. Resulting to 1.26 which is round to 6, make it 6 month payback period.

Payback period = Initial Investment/ Cash inflow.

The ROI or Return of Investment was computed by taking the amount the system benefit, subtracting it to the total cost. The quotient is equivalent to 99.9% and rounding off to 100% of ROI (Return of Investment). The formula that the proponents used can be seen on Figure 5.
