How do I get the Name and Address on the Invoice to show up in a Window Envelope?
This requires editing of the Contribution Invoice Receipt - Message Template. End result looks like this:

I'll detail the steps below to get the header part.



The header portion contains two tables: the first table is used to add your logo. The second table has the formatting for the Name and Address section: note that we're putting the Member's Name and Address on the far left and in a slight larger font.

   &lt;table width="100%" border = "0" style = "margin-top:20px;margin-right:40px;"&gt;
        &lt;tr&gt;
          &lt;td align="right" height="50"&gt;&lt;img src = "https://www.yoursite.com/sites/yoursite/files/logo_250x.png"&gt;&lt;/td&gt;
        &lt;/tr&gt;
   &lt;/table&gt;

   &lt;table width="100%" border = "0" cellpadding = "2" cellspacing = "1" style = "margin-top:35px;margin-right:20px; font-family: Arial, Verdana, sans-serif;"&gt;
        &lt;tr&gt;
          &lt;td width="40%" rowspan="3"&gt;&lt;b&gt;&lt;font size = "4" align = "center"&gt;{ts}INVOICE{/ts}&lt;/font&gt;&lt;/b&gt;&lt;/td&gt;
          &lt;td width="25%"&gt;&lt;b&gt;&lt;font size = "1" &gt;{ts}Invoice Date{/ts}&lt;/font&gt;&lt;/b&gt;&lt;font size = "2"&gt; &lt;/font&gt;&lt;/td&gt;
          &lt;td width="35%"&gt;&lt;font size = "1"&gt;{$domain_organization}&lt;/font&gt;&lt;/td&gt;
        &lt;/tr&gt;

        &lt;tr&gt;
          &lt;td&gt;&lt;font size = "1"&gt;{$invoice_date}&lt;/font&gt;&lt;font size = "2"&gt; &lt;/font&gt;&lt;/td&gt;
          &lt;td&gt;&lt;font size = "1"&gt;{$domain_street_address}&lt;/font&gt;&lt;/td&gt;
        &lt;/tr&gt;

       &lt;tr&gt;
          &lt;td&gt;&lt;font size = "1"&gt;&lt;/font&gt;&lt;font size = "2"&gt; &lt;/font&gt;&lt;/td&gt;
          &lt;td&gt;&lt;font size = "1"&gt;{if $domain_city}{$domain_city|upper}{/if} {if $domain_state }{$domain_state}{/if} {$domain_postal_code}&lt;/font&gt;&lt;/td&gt;
        &lt;/tr&gt;

        &lt;tr&gt;
          &lt;td&gt;&lt;font size = "2"&gt;{$display_name}&lt;/font&gt;&lt;/td&gt;
          &lt;td&gt;&lt;b&gt;&lt;font size = "1" align = "right"&gt;{ts}Invoice Number{/ts}&lt;/font&gt;&lt;/b&gt;&lt;/td&gt;
          &lt;td&gt;&lt;font size = "1"&gt;{if $domain_country}{$domain_country|upper}{/if}&lt;/font&gt;&lt;/td&gt;
        &lt;/tr&gt;

        &lt;tr&gt;
          &lt;td&gt;&lt;font size = "2"&gt;{$street_address} {$supplemental_address_1}&lt;/font&gt;&lt;/td&gt;
          &lt;td&gt;&lt;font size = "1"&gt;{$invoice_number}&lt;/font&gt;&lt;/td&gt;
          &lt;td&gt;&lt;font size = "1"&gt;{if $domain_email}{$domain_email}{/if}&lt;/font&gt;&lt;/td&gt;
        &lt;/tr&gt;

        &lt;tr&gt;
          &lt;td&gt;&lt;font size = "2"&gt;{$city|upper} {$stateProvinceAbbreviation} {$postal_code}&lt;/font&gt;&lt;/td&gt;
          &lt;td&gt;&lt;/td&gt;
          &lt;td&gt;&lt;font size = "1"&gt; {if $domain_phone}{$domain_phone}{/if}&lt;/font&gt; &lt;/td&gt;
        &lt;/tr&gt;

        &lt;tr&gt;
          &lt;td&gt;&lt;/td&gt;
          &lt;td&gt;&lt;b&gt;&lt;font size = "1"&gt;{ts}Reference{/ts}&lt;/font&gt;&lt;/b&gt;&lt;font size = "2"&gt; &lt;/font&gt;&lt;/td&gt;
          &lt;td&gt;&lt;/td&gt;
        &lt;/tr&gt;

       &lt;tr&gt;
          &lt;td&gt;&lt;/td&gt;
          &lt;td&gt;&lt;font size = "1"&gt;{$source}&lt;/font&gt;&lt;font size = "2"&gt; &lt;/font&gt;&lt;/td&gt;
          &lt;td&gt;&lt;/td&gt;
        &lt;/tr&gt;

    &lt;/table&gt;
