The Problem and its Background
Introduction
From the very earliest moments in the modern history of the
computer, the people and the business world have witnessed the
proliferation of computer system that obliges to meet the goal of
Information technology.
We have the completely new world of information and
communication readily available through computer.
With its excellent standards and innovative brand of services, its
aims are to provide business to prefer outrageous performance of
Online Sales and Inventory System of ACME Tacloban Hardware.
Through this advancement in information, traditional business
managers are threaten with decrease of sales and fluctuation of profit
if they would stick to their old manual system of handling business
transactions. That is why computerized system is recommend to make
transactions faster, accurate, efficient and effective. This study is gear
towards this goal.
Online Sales and Inventory of Tacloban ACME Hardware is an
inventory control system that is design to enhance the productivity of
a company’s material department. This system will help them to
transact through online, and for delivery.

Since the transactions were done manually, like book keeping,
billing, information and inventory, it gave a hard time recording
ordered items and keeping the records of stocks. Thus, proposed
Online Sales and Inventory System of Tacloban ACME Hardware will
help them to lessen to eliminate problems on sales, storage and
retrieval of inventory data for the inventory status.

Theoretical Framework
There are various problems in the existing sales and inventory
system has been detected using manual system in the preparation of
the Sales and Inventory in every company. The problem in the record
transaction as: Delays, errors, omission, and the like result of
misinformation to the management of the availability of stock and sold
items. Because of this problem its affect the effective decision on the
part of the management.
A proposed online sales and inventory system would eliminate all
this problems. Efficiency in the process obtained and brings
satisfaction for both management and company.
Sales and Inventories are materials stored, waiting for
processing, or experiencing processing. They are everywhere
throughout all sectors of the economy. Observation of almost any
company balance sheet, for example, reveals that a significant portion
of its assets comprises inventories of raw materials, components and
subassemblies within the production process, and finished goods. Most
managers don’t like inventories because they are like money placed in
a drawer, assets tied up in investments that are not producing any
return and, in fact, incurring a borrowing cost.
They also incur costs for the care of the stored material and are
subject to obsolescence. In the last two decades there has been a
Computer Studies Department
4Asian Development Foundation College
Tacloban City
spate of programs developed by industry, all aimed at reducing
inventory levels and increasing efficiency on the shop floor.
Nevertheless, in spite of the bad features associated with
inventories, they do have positive purposes. Raw material inventories
provide a stable source of input required for production. A large
inventory requires less replenishment and may reduce ordering costs
because of economies of scale. In-process inventories reduce the
impacts of the variability of the production rates in a plant and protect
against failures in the processes. Final goods and inventories provide
for better customer service.
There are other kinds of inventories, including spare parts
inventories for maintenance and excess capacity built into facilities to
take advantage of the economies of scale of construction. Because of
their practical and economic importance, the subject of inventory
control is a major consideration in many situations. Questions must be
constantly answered as to when and how much raw material should be
ordered, when a production order should be released to the plant, what
level of safety stock should be maintained at a retail outlet, or how in
process inventory is to be maintained in a production process. An
inventory is represented in the simple diagram of Fig. 1. Items flow into
the system, remain for a time and then flow out. Inventories occur
Computer Studies Department

Tacloban City
whenever the time an individual enters is different than when it leaves.
During the intervening interval the item is part of the inventory.
Figure 1. A system Component with inventory
Figure1 represents a manufacturing process that takes a fixed
amount of time. A product entering the box at one moment leaves the
box one hour later. Products arrive at a rate of 100 per hour. Clearly, if
we look in the box, we will find some number of items. That number is
the inventory level. The relation between flow, time and inventory level
that is basic to all systems is inventory level = (Flow rate) (Residence
time) (1) where the flow rate is expressed in the same time units as
the residence time. For example, we have inventory level = (100
products/hour) (1 hour) = 100 products.
These questions are amenable to quantitative analysis with the
help of inventory theory. The application of scientific knowledge of
managing sales and inventory control which is called computer-
assisted instruction is given importance today. What is given emphasis
in the job market are variety of issues and opportunities for the
graduates to realize and be aware the importance of computer skills
they need to acquire to the present demand of the modern version of
computer era.

Review of Related Literature and Studies
Foreign Literature
According to Jeff Wourio, online sales and inventory system are
designed to immediately record any and all sales and inventory
transactions. Not only does that mean timely and accurate sales
tracking, but this system also lets one readily identify inventory levels,
particularly when what you have on the books doesn’t jibe with actual
stock. Little is more maddening to a business owner than watching his
or her staff bogged down with inefficient, unproductive responsibilities,
from double-checking his inventory disparities to seemingly endless
cash-register reconciliation. Perhaps the greatest advantage to a
comprehensive point-of-sale network is the freedom it can afford on
personnel to devote their energy to what genuinely matters the most
helping customers.
According to Donald Reimer and Ravi Nayar they disclosed that
maintaining the right inventory levels is tough challenge. If not
properly managed, the inventory can result in a significant expense.
Looking over the shoulder is the lender who is concerned about the
cost of carrying too much inventory – which can affect profitability.
Fortunately, there are management information systems that
exist which use microcomputers and variety of industry specific

software. The cost of carrying inventory today has become a major
expenditure and requires immediate attention. The benefits of
inventory control far outweigh the costs. Any reduction in inventories,
whether it is raw material, work-in-process, finished goods or supplies,
can have a dramatic impact on your bottom line.
Industry averages suggest that a 20 percent reduction in
inventory is achievable with an online inventory control system. For a
company with a yearly sales volume of $1 million, such a reduction
would result in savings of $14,400 per year and would free up $48,000
of new dollars for reinvestment. For a company with a yearly sales
volume of $10 million, the figures are proportionately higher:$144,000
per year in savings and $480,000 in a new dollar for reinvestment.
According to www.udatasolutions..com/lumbergear.asp that was
founded in 2002,Unique Data Solutions began consulting with
hardwood lumber companies to grasp the unique requirements of the
hardwood lumber industry, and after years of research and
development, Lumbergear software was rolled out. Despite the fact
that we come from modest beginnings and have come a long way,
they continue to provide their customers with quality service and
innovative technology solutions.
Lumbergear sales and inventory software is a powerful,
affordable and easy to use lumber business management system that

increases efficiency in the workplace. They give control of hardwood
lumber inventory and costs. The system also features a core set of
modules that make it possible to run lumber operations effectively, and
get products to customers on time.
The aforementioned lumbergear system specifically helps
manage and maintain inventory and costs for hardwood lumber and
distribution, and wholesale operations. Lumbergear is flexible system
that can be used by wholesalers, kiln facilities, hardwood and softwood
lumberyards, brokers, lumber sales, and sawmills.
LumberCell is a new software add-on that works hand in hand
with Lumbergear in real-time. A mobile transaction processing system,

lost sales and instantaneous replenishment, where contrary to the
classical inventory theory; the knowledge of the demand distribution is
not available. Furthermore, they observe that only the sales quantity in
each period and lost sales are unobservable, that is, demand data are
censored.

The manager must make an ordering decision in each period
based only on historical sales data. Excess inventory is either
perishable or carried over to the next period. In this setting, they
propose non-parametric adaptive policies that generate ordering
decisions over time. It shows that the T-period average expected cost
of our policy differs from the benchmark newsvendor cost-the
minimum expected cost that would have incurred if the manager had
known the underlying demand distribution.
Local Literature
Salavador P. Catelo denoted the importance of the Philippine
Retail Food over the past decade. The Philippines witnessed a
substantial growth in the retail industry. Although there is dearth of
recent literature and statistics to support this observation, a
reconnaissance of places especially in the urban areas can attest to
this. Growth is seen not only in terms of numbers but more visible in
terms of size, investment on structure and modernization in operation.
Digal (2001) pointed out that the Philippine retail industry’s
performance comprises about 11 percent of the Gross Domestic
Product (GDP) in 1997. There are clear indications that this magnitude
has been more or less maintained in the past 3 years. Total retail sales
in 2002 increased by 11.1 percent and its GVA contributed 10.6
percent to GDP in the same year. About seventy-three percent (72.84
Computer Studies Department
16Asian Development Foundation College
Tacloban City
%) of this share was in the trade sub-sector while 25.43 percent was in
the service sector. From 1981 to 1997, the industry grew by 5.83
percent annually, outpacing the average annual GDP growth rate of
2.27 percent over the same period.
Combined with the wholesale sector, the industry absorbed 15
percent of the country’s employed labor in 1998 (Digal, 2001). The
food, beverage and tobacco industry contributed 37 percent of the
total employment in the wholesale and retail industry in the Philippines
in 1995. Within the food sector, 87 percent of the total employment
comes from small food retailers with less than 10 employees (Digal,
2001).
In the Philippines, food retailing industry involves a wide array of
sellers from the sidewalk vendors, wet and dry markets, sari-sari
stores, groceries, supermarkets, hyper marts, warehouse and discount
clubs and convenience stores. Food means brisk business. Food is
intricately linked with its culture and traditions. In the family, food
accounts for 43 percent of total expenditures. Outside the home,
eating has become lucrative for the retail business. Expenditures for
dining out, excluding corporate representation registered an average
growth rate of 15 percent to 20 percent per annum in the last 10
years. In the quick service or fast food segment, the total market in
2000 was over PhP 30 B. (Palma, 2005). According to the Family
Computer Studies Department
17Asian Development Foundation College
Tacloban City
Income and Expenditure Survey (FIES) of the National Statistics Office
(NSO), household spending on food increased by 26 percent from 1997
to 2000. Personal consumption expenditure (PCE) on food and
beverages in 2002 reached about PhP 448 B from PhP 401.7 B in 1998,
or an average annual growth rate of about 3 percent (Omana, 2005).
Motor Image Pilipinas (MIP), exclusive distributor of Subaru in the
Philippines reported a year-end sales performance of 602 units,
marking an increase of 100 percent from 2007. It also registered the
biggest growth in performance in the Philippine automotive industry
based on the figures released by the Chamber of Automotive
Manufacturers of the Philippines (CAMPI). Subaru has been the fastest
growing automotive brand since its arrival in 2006 and Motor Image
has announced plans to expand its business in 2009.
Since its arrival in 2006, Motor Image Pilipinas has continued to
sustain its growth in the market with Subaru establishing itself as the
premier sport-luxury in the country. In 2008, Motor Image launched
three new models that further strengthened its position in the market;
the luxury SUV Tribeca, the 300-hp WRX STI and the third generation
compact SUV, the Forester. Aside from these three models, Motor
Image has also made available other well- known Subaru models such
as the Outback, the Legacy and Impreza 2.0R variants.

According to www.helium.com Henry Sy started to work at an
early age of 12, usually manning the small family sari-sari store and
preparing the traditional way of recording the sales and inventory
control. Shortly, Sy thought of selling small portions of their grocery
items to accommodate customers buying small volumes of products.
Thus, the concept of retail marketing came to his mind. He entered the
buy-and-sell industry to obtained funds to start his own retail business.
Sy imported retail products from the US and sold it in the Philippines
and the rest as they say was history. Mr. Sy is now the CEO and the

An Online Inventory Control System can also help company with
new inventory management techniques such as Just-in-time (‘JIT’).
Such techniques cut the use of company resources such as

require error-free environments and better control over inventory since
the buffer zone to compensate for the errors is less.

and provide reports that help the healthcare facility do a better job of
managing its surgical instrument inventory. It is important to be aware
of which systems are currently available in the marketplace and what
they offer. Most computer management systems track the instrument
set through all processes and service. Others have additional options,
such as instructional features online, instruments preventive
maintenance reminders, and employee tracking for productivity.
Although an automated system may require a substantial initial
investment, it has proven to be a cost effective instrument
management program. According to Valerie DeVries, RN, sterile
processing manager at Lenox Hill\hospital in New York City. “It may
cost thousands of dollars, but it’s worth it”. Now we can find the trays.
At Lenox Hill, we have a outrageous volume of instruments inventory.
“However, the system requires maintenance, backup, and someone to
sit and input consistently”.
When it comes to inputting data, bar coding, is a valuable tool.
Inputting data using a bar code system is a definite time saver over
annual input as long as the information is recorded at time of use. Bar
coded trays and a bar code scanner provide improved tacking of
instrument sets. Using a tray system that provided a location for
labeling as well as the ability to bar code is a clear advantage.

Improving information management has become the critical
issue for most small retailers, says Judy Newdom, a principal of
Computer Sciences Corporation national retail practice, based in
Cleveland, As a result, cash registers at many small businesses have
been transformed into Online POS Systems. Silverman say he selected
the upgraded CounterPoint software after evaluating other packages
because it would run on the assortment of POS hardware his firm
already had. Switching to competing POS software would have
required Blades to purchase new hardware, he says.
The new version of CounterPoint gives the company a quicker, a
more accurate, and more detailed picture of its sales and inventory
than the previous version. Moreover, the program can be tied into the
firm’s accounting software. Dynamics, from Great Plains Software Inc.
of Fargo, N.D. This enables each sale to be entered instantly into the
accounting ledger.
The aforementioned related studies seem to reveal the strengths
and weaknesses of the Sales and Inventory System both local and
abroad. Thus, the writes cited the aforementioned studies since it
served as a guide to the present study.

batteries. The demand of the product of the company is high. So, the
company has to follow a proper inventory management system. The
company follows “Safety Stock” inventory management system.
Safety stock system helps the company to fulfill its market
demand. For instance, the demand of inventory is likely to fluctuate
from time to time. In particular, at certain points of time the demand
may exceed the anticipated level. In other words, a discrepancy
between the assumed and actual usage rate of inventory is likely to
occur in practice. Similarly, the receipt of inventory from the suppliers
may be delayed beyond the expected lead-time. The delay may arise
from strikes, floods, transportation and other bottlenecks. Thus, a firm
would come across situations in which the actual usage of inventory is
higher than anticipated level and or the delivery of the inventory from
the suppliers is delayed. The effect of increased and or slower delivery
would be a shortage of inventory. That is, the firm would face a stock-
out situation. This, in true, as explained in detail below, would disrupt
the production schedule and alienate the customers. The company
would, therefore, be well advised to a keep a sufficient safety margin
by having additional inventory to guard against stock-out situation.
Such stocks are called “Safety Stock”. This would act as a buffer or
cushion against a possible shortage of inventory caused either by
increased usage or delayed as the minimum additional inventory to

serve as a safety margin or buffer or cushion to meet an unanticipated
increase in usage resulting from an unusually high demand and or an
uncontrollable late receipt of incoming inventory.
RFID Tracks Jewelry Sales, Inventory of Middle East, they created
a study wherein once the tag is applied to a piece of jewelry, a store
employee uses a handled interrogator to capture the tag’s unique
identification number, then again on a daily basis for inventory
management. Any attempt to cut the cord disables the tag, making it
impossible to transfer it from one piece of jewelry to another one that
is cheaper in an attempt to disguise a theft. The data related to those
daily read is transferred to an inventory database managed by TJS’s
software service, and TJS forwards a daily report to the bank. The
database contains detailed information on each piece of jewelry. The
system can be operated as a stand-alone system or integrated with the
store’s IT system. Handheld interrogators manufactured by Feig
Electronics, or by PDA reader module supplier ACG, can be waved a
few inches above the jewelry to retrieve information about the item
from the database. When the store sells a product, employees scan the
label once, and then cut the tag, disabling it. The tags are then
returned to Sokymat, which removes the chips from the hard plastic
cases and put them into new casings. While the system offers special
advantages to the Middle East, where bank ownership is an attractive

option, the system has also caught the attention of jewelry retailers
worldwide. “From a technical point of view, it’s a solution for the whole
world,” Nasser says. “Not everyone needs a financing solution; instead,
it’s about inventory management.” TJS charges the stores a monthly
fee for the system, depending on the size of the retailer.
By June, Nasser says, its system will be deployed at 25 locations.
The company is not the only one offering an RFID solution for jewelry
retailers. French RFID systems manufacturer Tagsys and Swiss auto-ID
software solutions provider Solid have co-developed a 13.56 MHz RFID
system aimed at increasing inventory accuracy and reducing theft.
Swiss watch and jewelry maker de Grisogono has developed the
system at its stores in Geneva and Paris, and also plans to roll it out
across all 15 worldwide retail locations by the end of the year.

system through website via a pocket PC phone. Fifthly, a summary
report system for the manufacturing department and director.
The system will require an internet network for a computer PC or
laptop, and the GPRS communication network for a pocket PC phone.
After the application was implemented by sale persons, customers and
administrators, the result of order products through websites was very
satisfactory. It decreased the order processes, and at the same
brought information technology to apply to the sale process. It reduces
the processing time by 77.98 percent and increased satisfaction for all
users.
