| Accounting Policies [Abstract] | |
| Basis of Preparation | Basis of preparation The accompanying unaudited interim
condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in
the United States of America (“GAAP”). The condensed consolidated financial statements included herein are unaudited.
Such financial statements, in the opinion of management, contain all adjustments necessary to present fairly the financial position
and results of operations as of and for the periods indicated. All such adjustments are of a normal recurring nature. These interim
results are not necessarily indicative of the results to be expected for the fiscal year ending September 30, 2017 or for any
other period. Certain information and footnote disclosures normally included in the financial statements prepared in accordance
with accounting principles generally accepted in the United States have been condensed or omitted pursuant to the rules and regulations
of the Securities and Exchange Commission, and because of this, for further information, readers should refer to the financial
statements and footnotes thereto included in this Form 10 for the fiscal year ended September 30, 2016. The Company believes that
the disclosures are adequate to make the interim information presented not misleading. |
| Principals of Consolidation | Principals of Consolidation The accompanying consolidated financial
statements include the accounts of Stem Holdings, Inc.. and its wholly-owned subsidiary, Patch International, Inc. All material
intercompany accounts, transactions, and profits have been eliminated in consolidation. |
| Use of Estimates | Use of estimates The preparation of these financial
statements requires management to make judgments, estimates and assumptions that affect the application of accounting policies
and the reported amounts of assets, liabilities, income and expenses. Estimates and judgments used are based on management’s
experience and the assumptions used are believed to be reasonable given the circumstances that exist at the time the financial
statements are prepared. The significant estimates included in these financial statements are those associated with the assumptions
used to value options issued to consultants. Actual results may differ from these estimates. |
| Cash and Cash Equivalents | Cash and cash equivalents Cash and cash equivalents include
short-term investments with original maturities of three months or less and are recorded at cost, which approximates fair market
value given the short-term nature. |
| Concentrations of Credit Risk | Concentrations of Credit Risk Financial instruments that potentially
subject the Company to significant concentrations of credit risk consist primarily of cash. As of March 31, 2017, the Company
had deposits in a major financial institution that are held in a depository accounts and thus not covered by FDIC insurance. |
| Carrying Value, Recoverability and Impairment of Long-lived Assets | Carrying value, recoverability
and impairment of long-lived assets The Company follows Financial Accounting
Standards Board (“FASB”) Accounting Standards Codification (“ASC’) 360 to evaluate its long-lived assets.
The Company’s long-lived assets, which include property and equipment are reviewed for impairment whenever events or changes
in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company assesses the recoverability
of its long-lived assets by comparing the projected undiscounted net cash flows associated with the related long-lived asset or
group of long-lived assets over their remaining estimated useful lives against their respective carrying amounts. Impairment, if
any, is based on the excess of the carrying amount over the fair value of those assets. Fair value is generally determined using
the asset’s expected future discounted cash flows or market value, if readily determinable. If long- lived assets are determined
to be recoverable, but the newly determined remaining estimated useful lives are shorter than originally estimated, the net book
values of the long-lived assets are depreciated and amortized over the newly determined remaining estimated useful lives. The Company considers the following
to be some examples of important indicators that may trigger an impairment review: (i) significant under-performance or losses
of assets relative to expected historical or projected future operating results; (ii) significant changes in the manner or use
of assets or in the Company’s overall strategy with respect to the manner or use of the acquired assets or changes in the
Company’s overall business strategy; (iii) significant negative industry or economic trends; (iv) increased competitive pressures;
(v) a significant decline in the Company’s stock price for a sustained period of time; and (vi) regulatory changes. The Company
evaluates assets for potential impairment indicators at least annually and more frequently upon the occurrence of such events. Through March 31, 2017 the Company
has not experienced impairment losses on its long-lived assets. |
| Capitalization of Project Costs | Capitalization of Project Costs The Company’s policy is to
capitalize all costs that are directly identifiable with a specific property, would be capitalized if the Company had already
acquired the property, and when the property, or an option to acquire the property, is being actively sought after, and either
funds are available or will likely become available. All amounts shown capitalized prior to acquisition of a property are included
under the caption of Project Costs in the balance sheet. |
| Income Taxes | Income Taxes Income taxes are provided for the
tax effects of transactions reported in the financial statements and consist of currently due plus deferred taxes. Deferred tax
assets and liabilities are determined based on differences between financial reporting carrying amounts and the respective tax
bases of assets and liabilities, and are measured using tax rates and laws that are expected to be in effect when the differences
are expected to be recovered or settled. Valuation allowances are provided against deferred tax assets if it is more likely than
not that the deferred tax assets will not be realized. The Company follows the guidance
of FASB ASC 740-10 which relates to the Accounting for Uncertainty in Income Taxes, which seeks to reduce the diversity in practice
associated with the accounting and reporting for uncertainty in income tax positions. This interpretation prescribes a comprehensive
model for financial statement recognition, measurement, presentation and disclosure of uncertain tax positions taken or expected
to be taken in income tax returns. |
| Fair Value of Financial Instruments | Fair value of financial instruments As defined in the authoritative guidance,
fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between
market participants at the measurement date. To estimate fair value, the Company
utilizes market data or assumptions that market participants would use in pricing the asset or liability, including assumptions
about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated
or generally unobservable. The authoritative guidance establishes
a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted
quoted prices in active markets for identical assets or liabilities (“Level 1” measurements) and the lowest priority
to unobservable inputs (“Level 3” measurements). The three levels of the fair value hierarchy are as follows: Level 1 — Observable inputs
such as quoted prices in active markets at the measurement date for identical, unrestricted assets or liabilities. Level 2 — Other inputs that
are observable, directly or indirectly, such as quoted prices in markets that are not active, or inputs which are observable, either
directly or indirectly, for substantially the full term of the asset or liability. Level 3 — Unobservable inputs
for which there is little or no market data and which the Company makes its own assumptions about how market participants would
price the assets and liabilities. In instances in which multiple levels
of inputs are used to measure fair value, hierarchy classification is based on the lowest level input that is significant to the
fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value
measurement in its entirety requires judgment, and considers factors specific to the asset or liability. |
| Earnings Per Share | Earnings per share The Company presents basic and diluted
per share amounts (“EPS”) data for its common shares. Basic EPS is calculated by dividing the profit or loss attributable
to common shareholders of the Company by the weighted average number of common shares outstanding during the period. Diluted loss
per share is calculated based on the weighted-average number of outstanding common shares plus the effect of dilutive potential
common shares, using the treasury stock method. The Company’s calculation of diluted net loss per share excludes potential
common shares as of March 31, 2017 as the effect would be anti-dilutive (i.e. would reduce the loss per share). As of March 31,
2017, the Company had issued 300,000 options exercisable into the common stock of the Company outstanding (see footnote #6). |
| Emerging Growth Company | Emerging Growth Company The Company has elected to be an
emerging growth company as defined under the Jumpstart Our Business Startups Act of 2012 (“Jobs Act”). Included with
this election, the Company has also elected to use the provisions within the Jobs Act that allow companies that go public to continue
to use the private company adoption date rules for new accounting policies. Should the Company obtain revenues in excess of $1
billion on an annual basis, have its non-affiliated market capitalization increase to over $700 million as of the last day of
its second quarter, or raise in excess of $1 billion in public offerings of its equity or instruments directly convertible into
its equity, it will forfeit its status under the Jobs Act as an emerging growth company. |
| Property and Equipment | Property and Equipment Property and equipment is stated
at cost less accumulated depreciation and is depreciated using the straight-line method over the assets’ estimated useful
life as follows:
Buildings 20 years
Leasehold improvements Shorter of term of lease or economic life of improvement
Furniture and equipment 5 years
Signage 5 years Normal maintenance and repairs for
equipment are charged to expense as incurred, while significant improvements are capitalized. |
