| SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | 6 Months Ended |

| Accounting Policies [Abstract] | |
| Significant Accounting Policies [Text Block] | NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES |
| The accompanying condensed interim financial statements of 4net Software, Inc. (the "Company") are unaudited. In the opinion of management, the interim data includes all normally recurring adjustments, necessary for a fair presentation of the results for the interim period. The results of operations for the three months and six months ended March 31, 2015 are not necessarily indicative of the operating results for the entire year. | |
| The condensed interim financial statements included herein are prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosure normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America has been condensed or omitted pursuant to such rules and regulations. In the opinion of management, the disclosures made are adequate to make the information not misleading. These condensed interim financial statements should be read in conjunction with the financial statements and notes included in the Company's Form 10-K for the year ended September 30, 2014. | |
| USE OF ESTIMATES - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. | |
| CASH EQUIVALENTS - For purposes of reporting cash flows, management considers as cash equivalents all highly liquid investments with a maturity of three months or less at the time of purchase. At March 31, 2015, the Company had no cash equivalents. | |

| Going Concern [Abstract] | |
| Going Concern [Text Block] | NOTE 2 - GOING CONCERN |
| The accompanying condensed interim financial statements have been prepared on the basis of accounting principles applicable to a going concern which contemplates the realization of assets and extinguishment of liabilities in the normal course of business. As shown in the accompanying condensed interim financial statements, the Company has an accumulated deficit of approximately $3.4 million through March 31, 2015. As of March 31, 2015, the Company has no principal operations or significant revenue producing activities, which raises substantial doubt about its ability to continue as a going concern. The Company's condensed interim financial statements do not include any adjustments related to the carrying value of assets or the amount and classification of liabilities that might be necessary should the Company be unable to continue as a going concern. The Company's ability to establish itself as a going concern is dependent on its ability to merge with another entity. The outcome of this matter cannot be determined at this time. | |
