    how using emails will make your work easy.

     6.1.1. Understanding email
     E-Mail refers to a system of exchanging messages electronically over a computer 
    network between two or more email service users. These users must have e-mail 
    addresses which are hosted by an email service provider like Gmail, Yahoo Mail, 
    etc. An email service provider has a big server on which users who have emails 
    have dedicated space in which their email will be saved. It is like a Post Office 
    where every customer has a box in which all his/her mails are dropped and 

    withdrawn.

     The email client comes in two forms, a web-based version like Gmail, where 
    users must log in through their browser to access their emails, or a client-based 
    version such as Outlook, where users install software to access emails from 
    their local computer. For emails to arrive at the correct destination there are 

    protocols which handle this task.

     • Email format
     The following is a sample format of an e-mail address :

     username@hostcomputer.domainname

    Explanation :
    – username: It identifies the owner of the e-mail address.
    – @ (“at” sign): Separates the username from the rest of the address parts.
    – hostcomputer: The name of the remote server on which the e-mail 
    account is hosted. For example gmail, yahoo, and hotmail among others.
    – .(dot): Separates the domain name from the other part of the e-mail address.
    – Domain name : It identifies the type of institution offering the services.  

    For example, nkeza@gmail.com, nkeza is the username, gmail is the host 

    computer and .com is the domain name for a commercial organization.

     6.1.2. Creation of emails 
    In general to create an email the user will have to first write the email service 
    provider address in the browser’s address bar then fills the provided forms in 
    which personal information are filled. When one form is well filled, the user is

    1.1.1.Gmail environment

     Once the email account holder logs in, the window below will be displayed :

    The gmail window environment has different tabs including Compose, Inbox, 
    Sent, Drafts, Spam and Trash. In order to have access to the options provided 

    by those tabs click on them. The use of each tab is summarized below :

     Sending emails and attaching files
     To send an email first click on Compose found in the Gmail window then follow 
    the following steps :
     1. In the window that appeared, go in the “To” text area and write the 
    recipient email,
     2. If there are other people who will receive copies, click in “Cc” text area 
    and write the email which will receive a copy
     3. If there is an email to receive a blind copy Click in “Bcc” text area and

     1.1.2. Advantages of online communication using emails
    From what can be done using emails, it is obvious that online communication 
    using emails has many advantages. Those advantages are outlined below :
     • Flexible access to participate whenever and wherever 

    convenient

     Communication using emails can allow participants to communicate wherever 
    and whenever they are and the price of this communication is not dependent on 
    the distance and time. A person can send an email during the night, can send 
    an email when he/she is in a foreign country while this may not be possible for 
    some old communication means.

     
    • Real time and quick response
     If two parties are using the required devices, communication can be done in the 
    real time and the response can be immediate. This is not possible for example in 
    the Post Office system where a mail envelope has to pass through many carriers 
    until it is dropped in the recipient box.
     
    Cost Effective
     When communication is done through emails, no cost is required for travelling 
    from one city to another or one country to another. All to be done is just sign up 

    and create your account. It saves both money and time.

    Application activity 6.2
     1) Exchange emails with your colleagues asking them about your lessons
     2) While writing an email what is the use of the tools Cc and Bcc
     3) State at least 2 disadvantages that come with the use of emails.

     4) What are 3 advantages of email over traditional mail?

     1.1.Search engines

    Activity 6.3

    Observe the screenshot below got as a result for the search conducted 
    by a Senior 4 student in Accounting who searched from the internet for 

    information about Balance Sheet.


     Answer the questions below:
     1) What is the topic entered by the student in the search box?
     2) Did the student find the information about Balance Sheet that he/she 
    wanted? If No explain why it was not found.
     3) Write in the google search box the keywords Balance Sheet.in 
    finance. Describe the accuracy of the information you get.
     4) Now write the keywords Balance Sheet in finance inside quotation marks.
     5) Compare the results found in question 3 and 4 by filling the table below:

     Search Engines are programs that help the user look for and identify items 
    that corresponds to keywords or phrases specified from the World Wide 
    Web. Examples include Yahoo, Google, Bing and Ask among others which are 
    accessed respectively using the URLs yahoo.com, google.com, bing.com and 
    ask.com. As an accountant search engine are important when searching from 

    the internet information related to goods and services to buy, new clients, etc.

     1.1.1.Strategies to find specific information using search engine
     When conducting a search using a search engine one can get millions of search 
    results and find that none of those results is related to what should be expected. 
    What is need is therefore the ability to refine the search to get exactly what is 
    needed. Some search engines also help find less results compared to others 
    so change a search engine in order to get more accurate results. Below the 

    strategies for better search results are developed.

    a) Simplify the Search Terms 
    Some engines include Stop words in their searches. These are frequently used 
    words such as prepositions (in, of, on), conjunctions (and, but) and articles (a, 
    the), which means that the search results have more pages of search results than 
    needed. It is always good to eliminate stop words from the internet searches. 
    However, if the search is aimed at searching for a specific title or name that 

    includes them, they should then be included in the search term. 

    a) Use Quotation Marks 
    Enclosing a search term within quotation marks prompts the search engine to 
    search for that specific word or phrase. If the term is a single word, using quotation 
    marks will unnecessary variations which increase the number of search results. 
    For example, if searching for the word director, the researcher likely receives a 
    lot of results for direct, direction, directions, and so on. Typing “director” with 
    quotation marks, ensure that only results for that word are displayed.  

    If the search term is a phrase, the search will be for that specific phrase, rather 

    than for all the component words as individual items. For example, if searching 
    for the phrase director of
     
    human resources,
    without quotation marks, the search returns results based 
    on all of the words in the phrase. Thus, surrounding the term with quotation 

    marks, will generate results that feature this specific phrase. 

     a) Remove unhelpful words 
    The use of a hyphen, small dash or minus sign immediately before a word 
    excludes it from a search. For example, typing in marketing -digital will exclude 
    digital from the search engine, making it easier to find the information searched 
    for. Typing marketing -digital -social would allow researcher to get rid of both 

    marketing and social terms.

    b) Refine the search using operators 
    Other characters, known as operators allow to narrow down the internet 
    search in more precise ways. A few of those are explored here below: 

    • Wildcard searches:
    Use wild card character to represent any other 
    word to search for. In this case use the * symbol to represent any other 
    word. For example, searching for *man in the world returns results for 
    the richest man in the world, the tallest man in the world, the oldest man 
    in the world, and so on. Wildcard searches are also useful for example 

    when researcher do not know the full text to search for. 

    • Combination searches: This is a technic by which the searcher 
    combines search terms using boolean operators AND, OR, NOT, 
    NEAR.
    These operators enable user to search for two or more terms 
    simultaneously and is most useful when those terms are very similar. 
    For example, typing selling OR retailing, will return pages where either 
    of the terms is used, without both needing
     to be present. The AND operator ensures that the searcher receives only search 
    results that include two or more terms. Apart from these operators one can also 

    use NEAR

     • Search in a specific Site: Typing the URL of the website that the 
    searcher wishes to search and a search term limit the search to a 
    single website. For example, typing in the search box: reb.rw” Director 
    General” will return all the pages from reb.rw that contain the term 
    “Director General” 
    • Advanced search techniques using tilde sign (~) 

    When the tilde operator is placed in front of a keyword, it also searches for 

    words that are synonyms of that keyword. The searcher can use the tilde 
    operator (~) to get Google or other search engines to expand the search with 
    related keywords. This is helpful when one does not know the entire search 

    query to use.

    Application activity 6.3
     Using the different search technics you have learned, search for the 
    following by making sure that you get more accurate results:
     1)  How taxes are collected in East Africa

     2)  Causes of economic crises

    6.4. Online sales and purchase process

    Activity 6.4

     Mushoramari wants to start a new business in which he will be selling car 
    spare parts to clients around the country. He wants to use emails in most 
    communications to replace physically meeting his clients so as to reduce 
    some costs to clients. 

    Explain how the sale and purchase process will be conducted in regard to 

    these concepts: inquiry, quotation.

    Online sale is the use of internet and other electronic means to sell goods and 
    services to clients who are not physically present at the selling agent. For these sales 
    to be possible sellers use web sites, search engines, social media, e-mail and other 
    electronic means to request or provide information from sellers.
    Online sale goes 
    together with online purchase. Online purchase  allows consumers to directly buy 

    goods or services from a seller using the same channel as in online sale.

    Online sales and purchase goes in a certain process in order to ensure that 
    when the seller and buyer conclude their deal both are satisfied. An online sale 
    and purchace using email can be conducted by following the process outlines 
    below:

     

    A) Inquiry
    Exercice 1: Role play
     Inquiry is a process by which a person asks and gets information from someone 
    having more knowledge therefore resolving doubt. While doing an online 
    purchase inquiry can be conducted from the seller in order to know the kind of 
    products sold. In this phase, the buyer who may have a big idea of the product 
    to buy will ask for additional information like the product specification, price, 
    possibilities of a discount, packaging options, delivery methods and duration, 
    etc. After the buyer and the seller have agreed on the product, the seller sends 

    quotation to the buyer.

     You are an investor specialized in hospitality specifically hotels and you want to 
    buy plates for one of your hotels in Rwanda. Write to an industrialist involved 
    in manufacturing asking him/her about plates you want to buy. Use your Gmail 

    account to do this. 

    A) Quotation
     A quotation is a document that a seller provides to a buyer to offer goods or 
    services at a stated price, under specified conditions. Quotations are used to let 
    a potential buyer know how much goods or services will cost before they decide 
    to buy. A quotation should include among other the price, an expiration date, 

    your company details and your customer’s details.

     A quotation also represents the brand identity and professionalism. If it looks 
    not attractive and not well-structured, the potential buyers will assume that the 
    business is not well run while if this quotation is well presented this can be a 

    sign of attention to details and the value of service provided.

     Qualities of a good quotation
     
    For a quotation to be an incentive for buying, it should meet the following :

    – Visual content : Images convey easily a message than words. It is 
    therefore good to make the service more visual by including reference 
    images, videos and graphs that best reflect the process and the results. 
    Visuals will help to paint a clearer picture of what will be working on 
    and enable to demonstrate all unique features of product/service in a 
    clear fashion.
    – Design and format :
    It is good to have quotations which are in an 
    attractive design. To be attractive, these quotations should also have 

    appropriate and attractive colors.

     Exercise 2: Role play
     1. You are the hotelier in Exercise 1 and you have got satisfying information 
    from the industrialist manufacturer. Now write to him/her requesting for a 

    quotation for the plates you want to buy.

    quotation using your Gmail account.

     3. You are an investor specialized in hospitality specifically hotels and 
    you want to buy plates for one of your hotels in Rwanda. Write to an 
    industrialist involved in manufacturing asking him/her about plates you 

    want to buy. Use your Gmail account to do this. 

    A) Order
     Writing an order for goods and service is done when the customer has been 
    satisfied with the information provided in the quotation. An order should among 

    others include a list of items required with the quantities.

    Exercise 3: Role play
     a) You are the hotelier (in Exercise 1 and 2). Write an order of the plates 
    you want to buy.
     b) You are the Industrialist, respond to the customer from which you have 
    received the order.
     a) Invoice
     An invoice is a commercial document issued by the seller to the client about a 
    sell transaction. This document shows the products, quantities and the price 
    that were agreed on between the seller and the buyer.
     
    Exercise 4: Role play

     1) You are the industrialist manufacturer who received an order (in Exercise 
    3). Write an invoice to your customer.

     
    A) Goods delivery note
     A goods delivery note accompanies the goods sent to the buyer. It shows a list 
    of the products and the quantity of the goods included in the delivery.

     
    Exercise 5: Role play
     You are the industrialist who sent the goods that were ordered by the hotelier. 
    Now send the goods delivery note to the customer.
     
    Application activity 6.4

     Divide in two groups and play the role of buyer and seller then:
     1) Imagine you are an owner of a company that sell planes
     2) As customer and buyer interact so as to show all the process 
    involving inquiry, quotation, order, invoice, Goods delivery note
     You may use internet to get information to help you do this role play.

     6.5.1. Introduction to E-commerce
     E-Commerce or Electronic Commerce also known as e-Business, is the buying 
    and selling of goods, products, or services over the internet using electronic 

    means of payment like credit cards. 

    The history of e-commerce dates back to the invention of the very old notion 
    of “sell and buy”, electricity, cables, computers, modems, and the Internet. 
    E-commerce became possible in 1991 when the Internet was opened for 

    commercial use.

     At first, the term e-commerce meant the process of execution of commercial 
    transactions electronically which gives an opportunity for users to exchange 
    business information and do electronic transactions. The ability to use these 
    technologies appeared in the late 1970s and allowed business companies and 

    organizations to send commercial documentation electronically.

     6.5.2. E-commerce models
     Electronic commerce can be classified into four main categories. The basis for 
    this simple classification is the parties that are involved in the transactions. The 

    four basic electronic commerce models are:

     a) Business to Business
     In a business to business model companies are doing business with each other. 
    The final consumer is not involved. So, the Online transactions only involve the 

    manufacturers, wholesalers and retailers, etc.

     b) Business to Consumer
     Here the company will sell their goods and/or services directly to the consumer. 
    The consumer can browse their websites and look at products, pictures, read 
    reviews. Then, they place their order and the company ships the goods directly to them.
     
    c) Consumer to Consumer

     Consumers are in direct contact with each other. No company is involved. It 
    helps people sell their personal goods and assets directly to an interested person.
     
    d) Consumer to Business

    The consumer provides goods or services to the company.

     6.5.3. Online shopping malls
     Around the world and in Rwanda there are different companies which sell goods 
    online. Some of them are Alibaba, Amazon, Kikuuu, Vuba Vuba. For every online 
    shopping mall buying goods is done in this way:
    – The client creates an account on the online shopping mall. This account 

    will allow the client to be uniquely identified in the mall’s online system. 
    In order to create an account, open a web browser and enter the 
    address of the mall in the address bar of that browser and follow the 
    directives found on that platform,
    – The client with an account uses his/her account credentials to login in 

    the system. The credentials most of the time consist of user name and 
    password,
    – Now that the client has logged in the system, she/he chooses the 

    goods to buy. In the mall’s system, goods are shown with their names, 
    images and prices. The price to pay add up as the client selects more 
    goods to buy.
    – The client chooses the payment methods like MTN Mobile Money, Tigo 
    Cash. There are also other payment methods which can be used like 
    credit/debit cards, bank transfers, etc
     
    a) Local online shopping malls
     Kikuu is one of the e-commerce platforms available in Rwanda with which one 
    can buy available goods and have them delivered to his/her preferred location 
    in Kigali. When a client wants to buy from Kikuu he/she visit the platform kikuu.

     6.6.1. E-procurement
     • Definition

     E-procurement is the buying and selling of goods and services using internet 
    through dedicated web applications. E procurement is designed to centralize 
    and automate interactions between organizations, customers and other parties 
    in the procurement so as to increase the speed and efficiency of this process 
    (procurement).
     • The benefits of e procurement include :
    – Automation of tasks which otherwise would be laborious. Those tasks 

    are like document management for purchase orders, evaluating and 
    selecting suppliers, storing supplier contracts, etc
    – The procuring process becomes less centralized meaning that both the 

    client and the procuring entity can view the status of the procurement 
    anywhere and anytime
    – Reduces the risk of corruption and document loss as every action done 

    in the procurement system is recorded. It is not possible for example to 
    remove a submitted file and pretend that it was not submitted but this 
    can be done in a paperbased procurement.
    • Procurement web application in Rwanda
     As many sectors are being computerized, procurement was not left behind. That 
    is why there is in place a system umucyo.gov.rw which is used in procurement 
    in order to make it quick and easy. The features of this system can be accessed 
    when the user is not logged but personified features are accessed when the 
    user is logged. When not logged one can have access to the list of procurement 

    plan both in the current financial year and the old financial years.

    6.6.2. E-tax
     In Rwanda, taxes are collected by Rwanda Revenue Authority while there are 
    also taxes collected at the local level. These taxes are collected using the RRA 
    website which is linked to an application to allow tax declaration. There is also a 
    Rwanda Trade Portal (rwandatrade.rw/) which is used to calculate import duties 
    and taxes. This application is connected to the Rwanda custom database which 

    makes it calculate accurately the taxes to be paid.

    6.6.3. E- payment--
     E-payment is a way of carrying out transactions or paying for goods and 
    services using an electronic medium without using the traditional way of 
    payment involving cash or check. This payment can be between people, 
    between people and institutions, between institutions.
     Inside the country the e-payment between people can be done using 
    MTN Mobile Money, Airtel Money or Tigo Cash. The e-payment from 
    institutions to people can be done using different application which 
    allows a depositing of money from the institution account to the people’s 
    accounts. For example the payment of salaries to public servants is done 

    using MINECOFIN system. 

    Exercise: 
    Do a research on how public institutions pay their staff using e-payment means. 
    Your findings should include: the name of the system, the process of payment 

    and how to prevent fraud in the payments.

    • Characteristics of an e-payment system
     As E-payments systems are used for managing the payment of money, no error 
    is allowed. The main characteristics of an epayment system in order to prevent 
    errors to the maximum are the following :
    – Security:
    Because e-payment systems involve actual money, it is more 
    likely that criminals will attack these systems. Therefore these system 
    must be protected against any cyber attack.
    – Reliability
    : As more services adopt e-payment, all the life in a 
    country will depend on the e-payment systems. Therefore any problem 
    encountered by that system will greatly impact the whole country. This 
    explains why e-payment systems should be always available and should 
    not fail.
    – Scalability: The internet is growing rapidly and people migrating from 
    the old way of payment to e-payment increase rapidly. An e-payment 

    system must be able to accommodate an increase in number of people 

    using it and must not crash, be unavailable or lose its performance 
    because the number of transactions has increased. Therefore an 
    e-payment system must support the addition of infrastructure without 

    stopping the service.

    – Anonymity : There are transactions for which the identity of the parties 
    to the transaction should be protected. An e-payment system should 

    therefore allow this anonymity when it is needed.

     Application activity 6.6
     Visit the web applications that are used for procurement, tax calculation, 
    e-payment.
     3) What is the feature found in the e-procurement application?
     4) Describe what you can do when using the e-tax application. What are 
    its advantages compared to when there was not a web application to do it?
     5) Do a research and enumerate services in Rwanda which are paid 
    using e-payment systems. For each service show the system used.
