  <title>Accounts Receivable</title>

  <para>Accounts Receivable (or A/R) refers to products or services provided
  by your company for which payment has not yet been received.</para>

  <sect1 id="bus-ar-overview1">
    <title>Overview of Business Features</title>

    <para>The accounting needs of a business are quite different from that of
    a person. Businesses have customers that owe money, vendors which are owed
    money, employee payroll, more complex tax laws, etc. <application>&app;</application> offers
    business oriented features to facilitate these needs.</para>

    <para>Accounts Receivable (A/R) are used by businesses to record sales for
    which they are not immediately paid. Accounts Payable (A/P) record bills
    that they have received, but might not pay until later. These types of
    accounts are used primarily when you have a lot of bills and receipts
    flowing in and out, and do not want to lose track of them just because you
    do not pay or get paid right away. For most home users, A/R and A/P are
    too complicated to be worth the effort.</para>
  </sect1>

  <sect1 id="bus-ar-concepts1">
    <title>Basic Concepts</title>

    <para>Accounts Receivable (or A/R) refers to products or services provided
    by your company for which payment has not yet been received. This is
    represented on the balance sheet as an asset, because the expectation is
    that you will receive payment soon.</para>
  </sect1>

  <sect1 id="bus-ar-setup1">
    <title>Initial Setup</title>

    <para>To set up <application>&app;</application> to handle accounts receivable for a company two
    preliminary things must be done. The first is to build an appropriate
    Account Hierarchy and the second is to register the company in
    <application>&app;</application>.</para>

    <sect2 id="bus-ar-setupacct2">
      <title>Account Setup</title>

      <para>There are many different ways to set up a business account
      hierarchy. You can start with the Business Accounts setup which is
      available from the New Account Hierarchy assistant, or you could build one
      manually. To access the prebuilt Business Accounts, start <application>&app;</application> and
      click on <menuchoice><guimenu>File</guimenu><guimenuitem>New File</guimenuitem></menuchoice> and
      proceed until you see the list of available accounts, select Business
      Accounts.</para>

      <para>The prebuilt Business Account hierarchy will not meet your needs
      exactly. You will need make adjustments for the hierarchy to function
      well with your particular situation. It should be close enough that it
      is recommended you begin with it.</para>

      <para>Accounts Receivable (or A/R) refers to products or services
      provided by the company on credit for which payment has not yet been
      received. This is represented on the balance sheet as an asset, because
      you expect to receive payment soon. To use <application>&app;</application>&rsquo;s integrated accounts
      receivable system, you must first set up an account (usually a
      sub-account under Assets) defined with account type
      <emphasis>A/Receivable</emphasis>. It is within this account that the
      integrated A/R system will place transactions.</para>

      <literallayout>
Basic A/R Account Hierarchy:

-Assets
   -Checking
   -Accounts Receivable
-Income
   -Sales
  </literallayout>

      <para>You need to add additional asset, expense, and income accounts to
      this hierarchy for it to be useful. The important aspects of this
      hierarchy are the use of an income account and the Accounts Receivable
      asset account, with account type set to
      <emphasis>A/Receivable</emphasis>.</para>

      <note>
        <para>You do not need to create an individual A/R account for each
        customer. <application>&app;</application> keeps track of customers internally and provides
        per-customer reports based on the internal tracking.</para>

    <para>Give a <guilabel>Name</guilabel> to the new style sheet (e.g. <guilabel>Custom Invoice</guilabel>) and select the 
    <guilabel>Fancy</guilabel> <guilabel>Template</guilabel>. When you click the
    <guibutton>OK</guibutton> button, the <guilabel>HTML Style Sheet Properties</guilabel> window is
    displayed. This window presents you five sections listed in the left pane: <guilabel>Colors</guilabel>, <guilabel>Fonts</guilabel>,
    <guilabel>General</guilabel>, <guilabel>Images</guilabel>, and <guilabel>Tables</guilabel>. The <guilabel>Colors</guilabel>
    section allows you to change the colors of various items of the invoice. The <guilabel>Fonts</guilabel> section lets you
    set fonts type and dimensions. The <guilabel>General</guilabel> section allows you to set the <guilabel>Preparer</guilabel> and
    <guilabel>Prepared for</guilabel> information, and to <guilabel>Enable Links</guilabel>. The <guilabel>Images</guilabel> section allows you
    to import graphics into the style sheet. The <guilabel>Tables</guilabel> section allows you to
    adjust the spacing around the tables which make up the invoice.</para>

    <para>To include a company logo, banner heading and background image, use
    your favorite graphics application such as <application>The Gimp</application> or <application>OpenOffice Draw</application> to
    save the images in either <acronym>GIF</acronym> or <acronym>PNG</acronym> format. Then import them into the
    style sheet using the <guilabel>Images</guilabel> section described above.</para>

    <para>Below is an example that imports all three types of images.</para>

    <note>
      <para>The images are placed in the invoice as follows. The
      <guilabel>Background Tile</guilabel> is tiled to become the background
      image, the <guilabel>Heading Banner</guilabel> goes to above the invoice
      text, and the <guilabel>Logo</guilabel> is placed in the upper left corner
      of the invoice to the left of the Heading Banner. You will probably have
      to try a few different sized images until you get the invoices to print
      nicely. Some sizing suggestions are that the Logo should be 1 square cm
      (~0.5 inch), and the Heading Banner should be 15 cm (~6 inches) wide and 1
      cm (~0.5 inch) tall.</para>
    </note>

    <para>With the style sheet configured, when you print the invoice, you
    select the style sheet to use from the <guimenu>Options</guimenu> menu.
    Below is the resultant invoice after applying the style sheet demonstrated
    above.</para>
