The Company&amp;#8217;s current strategy is to raise capital  and invest that capital in such a way that the Company rapidly  grows its market share and revenues, eventually resulting in  profits and cash from operations. However, this strategy has  required a rapid build-up of infrastructure that initially  exacerbated the Company&amp;#8217;s operating deficit and use of cash  in operations, because the expected revenue expansion will lag the  investment in infrastructure. The capital that the Company has  raised, and likely will continue to raise, will be used to invest  in infrastructure, to fund development of the software product, to  fund incremental legal and accounting costs associated with being a  public company and to fund the Company&amp;#8217;s operating deficit  and general working capital requirements.&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt"&gt;  &amp;#160;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  During the six months ended June 30, 2013 and the twelve months  ended December 31, 2012, the Company generated approximately $&lt;font  style=" FONT-SIZE: 10pt"&gt;1,486,000&lt;/font&gt; and $&lt;font style=" FONT-SIZE: 10pt"&gt;4,561,000&lt;/font&gt; in cash from financing  activities, respectively, from factoring its receivables and from  private offerings of common stock, warrants and debt funding. This  capital has permitted the Company to continue its investment in  product development and has provided working capital for the  Company to win a modest amount of new business throughout the first  six months of 2013. However, the amount of new business generated  did not support the Company&amp;#8217;s increased infrastructure and  due to cash constraints the Company was forced to reduce costs  until such time that either the anticipated level of revenue  materializes or the Company raises sufficient additional  capital.&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt"&gt;  &amp;#160;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &lt;font style="COLOR: black"&gt;During the six months ended June 30,  2013 and 2012, the Company recorded net losses of approximately  $&lt;font style=" FONT-SIZE: 10pt"&gt;3,244,000&lt;/font&gt; and $&lt;font style=" FONT-SIZE: 10pt"&gt;4,901,000&lt;/font&gt;, respectively. Through cost  reduction measures, the Company decreased its net loss during the  six months ended June 30, 2013 despite revenues decreasing to  approximately $&lt;font style=" FONT-SIZE: 10pt"&gt;964,000&lt;/font&gt; from  approximately $&lt;font style=" FONT-SIZE: 10pt"&gt;1,877,000&lt;/font&gt; in  the prior period. During the six months ended June 30, 2013 and  2012, the Company used cash in operating activities of  approximately $&lt;font style=" FONT-SIZE: 10pt"&gt;1,332,000&lt;/font&gt; and  $&lt;font style=" FONT-SIZE: 10pt"&gt;3,283,000&lt;/font&gt;, respectively. As  of June 30, 2013, the Company had limited cash of approximately  $&lt;font style=" FONT-SIZE: 10pt"&gt;162,000&lt;/font&gt;, a working capital  deficiency of approximately $&lt;font style=" FONT-SIZE: 10pt"&gt;8,368,000&lt;/font&gt;, an accumulated deficit of  approximately $&lt;font style=" FONT-SIZE: 10pt"&gt;46,724,000&lt;/font&gt; and  owes approximately $&lt;font style=" FONT-SIZE: 10pt"&gt;1,377,000&lt;/font&gt;  for payroll tax liabilities, penalties and interest which has yet  to be remitted to the taxing authorities.&lt;/font&gt; The IRS has placed  federal tax liens that aggregate to approximately $&lt;font style=" FONT-SIZE: 10pt"&gt;&lt;font style=" FONT-SIZE: 10pt"&gt;&lt;font style="BACKGROUND-COLOR: transparent"&gt;771,000&lt;/font&gt;&lt;/font&gt;&lt;/font&gt;  against the Company in connection with the unpaid payroll taxes  through the third quarter of 2012.&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt"&gt;  &amp;#160;&amp;#160;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &lt;font style="COLOR: black"&gt;Subsequent to June 30, 2013, the Company  completed one closing of a private placement offering in which the  Company sold $190,925&amp;#160;of units at a price of $&lt;font style=" FONT-SIZE: 10pt"&gt;10,000&lt;/font&gt; per unit. Each unit consists of  (i) $&lt;font style=" FONT-SIZE: 10pt"&gt;10,000&lt;/font&gt; principal amount  of one year, &lt;font style=" FONT-SIZE: 10pt"&gt;12&lt;/font&gt;% secured  convertible promissory notes and (ii) a five-year warrant to  purchase &lt;font style=" FONT-SIZE: 10pt"&gt;267&lt;/font&gt; shares of common  stock at a price of $&lt;font style=" FONT-SIZE: 10pt"&gt;3.00&lt;/font&gt; per  share at any time after the maturity date of the notes. On August  14, 2013, the Company borrowed $250,000 via a short-term interest  free loan from an affiliate. The loan is intended to convert into  the Units Offering. The capital raised in the private placement  offering will be utilized to fund existing operating deficits while  the Company continues to develop product line(s) and enhance  marketing efforts to increase revenues and eventually generate  operating surpluses. The Company believes it will be successful in  these efforts; however, there can be no assurance the Company will  meet its revenues forecasts or, if necessary, be successful in  raising additional debt or equity financing to fund its operations  on terms agreeable to the Company. These matters raise substantial  doubt about the Company&amp;#8217;s ability to continue as a going  concern. The financial statements do not include any adjustments  that might be necessary if the Company were unable to continue as a  going concern. The Company expects that the cash it has available  will fund its operations only until September 2013.&lt;/font&gt; If &lt;font  style="COLOR: black"&gt;the Company&lt;/font&gt; is unable to obtain  additional financing on a timely basis and, notwithstanding any  request &lt;font style="COLOR: black"&gt;the Company&lt;/font&gt; may make,  &lt;font style="COLOR: black"&gt;the Company&amp;#8217;s&lt;/font&gt; debt holders  do not agree to convert their notes into equity or extend the  maturity dates of their notes, &lt;font style="COLOR: black"&gt;the  Company&lt;/font&gt; may have to delay note and vendor payments and/or  initiate cost reductions, which would have a material adverse  effect on &lt;font style="COLOR: black"&gt;the Company&amp;#8217;s&lt;/font&gt;  business, financial condition and results of operations, and  ultimately &lt;font style="COLOR: black"&gt;the Company&lt;/font&gt; could be  forced to discontinue its operations, liquidate, and/or seek  reorganization under the U.S. bankruptcy code.&lt;/div&gt;  &lt;/div&gt;        </NonNumbericText><FootnoteIndexer /><CurrencyCode /><CurrencySymbol /><IsIndependantCurrency>false</IsIndependantCurrency><ShowCurrencySymbol>false</ShowCurrencySymbol><DisplayDateInUSFormat>false</DisplayDateInUSFormat></Cell></Cells><ElementDataType>nonnum:textBlockItemType</ElementDataType><SimpleDataType>na</SimpleDataType><ElementDefenition>Going Concern Disclosure</ElementDefenition><ElementReferences>No definition available.</ElementReferences><IsTotalLabel>false</IsTotalLabel><UnitID>0</UnitID><Label>Liquidity, Going Concern and Management's Plans</Label></Row></Rows><Footnotes /><IsEquityReport>false</IsEquityReport><ReportName>Liquidity, Going Concern and Management's Plans</ReportName><MonetaryRoundingLevel>UnKnown</MonetaryRoundingLevel><SharesRoundingLevel>UnKnown</SharesRoundingLevel><PerShareRoundingLevel>UnKnown</PerShareRoundingLevel><ExchangeRateRoundingLevel>UnKnown</ExchangeRateRoundingLevel><HasCustomUnits>true</HasCustomUnits><IsEmbedReport>false</IsEmbedReport><IsMultiCurrency>false</IsMultiCurrency><ReportType>Sheet</ReportType><RoleURI>http://www.CK0001476638.com/role/LiquidityGoingConcernAndManagementsPlans</RoleURI><NumberOfCols>1</NumberOfCols><NumberOfRows>2</NumberOfRows></InstanceReport>
