Accounting Policies [Abstract]
Consolidation	The condensed consolidated financial statements include the accounts of JHA and all of its subsidiaries, which are wholly-owned, and all intercompany accounts and transactions have been eliminated.
Revenue Recognition	Revenue Recognition The Company generates revenue from data processing, transaction processing, software licensing and related services, professional services, and hardware sales. Significant Judgments in Application of the Guidance Identification of Performance Obligations The Company enters into contracts with customers that may include multiple types of goods and services. At contract inception, the Company assesses the solutions and services promised in its contracts with customers and identifies a performance obligation for each promise to transfer to the customer a solution or service (or bundle of solutions or services) that is distinct - that is, if the solution or service is separately identifiable from other items in the arrangement and if the customer can benefit from the solution or service on its own or together with other resources that are readily available. The Company recognizes revenue when or as it satisfies each performance obligation by transferring control of a solution or service to the customer. Determination of Transaction Price The amount of revenue recognized is based on the consideration the Company expects to receive in exchange for transferring goods and services to the customer. The Company’s contracts with its customers frequently contain some component of variable consideration. The Company estimates variable consideration in its contracts primarily using the expected value method, based on both historical and current information. Where appropriate, the Company may constrain the estimated variable consideration included in the transaction price in the event of a high degree of uncertainty as to the final consideration amount. Taxes collected from customers and remitted to governmental authorities are not included in revenue. The Company includes reimbursements from customers for expenses incurred in providing services (such as for postage, travel and telecommunications costs) in revenue, while the related costs are included in cost of revenue. Technology or service components from third parties are frequently included in or combined with the Company’s applications or service offerings. Whether the Company recognizes revenue based on the gross amount billed to the customer or the net amount retained involves judgment in determining whether the Company controls the good or service before it is transferred to the customer. This assessment is made at the performance obligation level. Allocation of Transaction Price The transaction price, once determined, is allocated between the various performance obligations in the contract based upon their relative standalone selling prices. The standalone selling prices are determined based on the prices at which the Company separately sells each good or service. For items that are not sold separately, the Company estimates the standalone selling prices using all information that is reasonably available, including reference to historical pricing data. The following describes the nature of the Company’s primary types of revenue: Processing Processing revenue is generated from transaction-based fees for electronic deposit and payment services, electronic funds transfers and debit and credit card processing. The Company’s arrangements for these services typically require the Company to “stand-ready” to provide specific services on a when and if needed basis by processing an unspecified number of transactions over the contractual term. The fees for these services may be fixed or variable (based upon performing an unspecified quantity of services), and pricing may include tiered pricing structures. Amounts of revenue allocated to these services are recognized as those services are performed. Customers are typically billed monthly for transactions processed during the month. The Company evaluates tiered pricing to determine if a material right exists. If, after that evaluation, we determine a material right does exist, we assign value to the material right based upon standalone selling price. Outsourcing and Cloud Outsourcing and cloud revenue is generated from data and item processing services and hosting fees.The Company’s arrangements for these services typically require the Company to “stand-ready” to provide specific services on a when and if needed basis. The fees for these services may be fixed or variable (based upon performing an unspecified quantity of services), and pricing may include tiered pricing structures. Amounts of revenue allocated to these services are recognized as those services are performed. Data and item processing services are typically billed monthly. The Company evaluates tiered pricing to determine if a material right exists. If, after that evaluation, we determine a material right does exist, we assign value to the material right based upon standalone selling price. Product Delivery and Services Product delivery and services revenue is generated primarily from software licensing and related professional services and hardware delivery. Software licenses, along with any professional services from which they are not considered distinct, are recognized as they are delivered to the customer. Hardware revenue is recognized upon delivery. Professional services that are distinct are recognized as the services are performed. Deconversion fees are also included within Product delivery and services, and are considered a contract modification. Therefore, the Company recognizes these fees over the remaining modified contract term. In-House Support In-house support revenue is generated from software maintenance for ongoing client support and software usage, which includes a license and ongoing client support. The Company’s arrangements for these services typically require the Company to “stand-ready” to provide specific services on a when and if needed basis. The fees for these services may be fixed or variable (based upon performing an unspecified quantity of services). Software maintenance fees are typically billed to the customer annually in advance and recognized ratably over the maintenance term. Software usage is typically billed annually in advance, with the license delivered and recognized at the outset, and the maintenance fee recognized ratably over the maintenance term. Accordingly, the Company utilizes the practical expedient which allows entities to disregard the effects of a financing component when the contract period is one year or less.
Contract Assets and Liabilities [Policy Text Block]	Contract assets primarily result from revenue being recognized when or as control of a solution or service is transferred to the customer, but where invoicing is contingent upon the completion of other performance obligations or contract milestones. The current portion of contract assets is reported within prepaid expenses and other in the condensed consolidated balance sheet, and the non-current portion is included in other non-current assets. Contract Liabilities (deferred revenue) primarily relate to consideration received from customers in advance of delivery of the related goods and services to the customer. Contract balances are reported in a net contract asset or liability position on a contract-by-contract basis at the end of each reporting period. The Company analyzes contract language to identify if a significant financing component does exists, and would adjust the transaction price for any material effects of the time value of money if the timing of payments provides either party to the contract with a significant benefit of financing the transaction.
Capitalized Contract Costs [Policy Text Block]	The Company incurs incremental costs to obtain a contract as well as costs to fulfill contracts with customers that are expected to be recovered. These costs consist primarily of sales commissions incurred only if a contract is obtained and customer conversion or implementation related costs. Capitalized costs totaled $200,870 and $181,032, at September 30, 2018 and June 30, 2018, respectively. Capitalized costs are amortized based on the transfer of goods or services to which the asset relates, in line with the percentage of revenue recognized for each performance obligation to which the costs are allocated.
Property, Plant and Equipment	Property and equipment is stated at cost and depreciated using the straight-line method over the estimated useful lives of the assets.
Intangible Assets	Intangible assets consist of goodwill, customer relationships, computer software, and trade names acquired in business acquisitions in addition to internally developed computer software. The amounts are amortized, with the exception of those intangible assets with an indefinite life (such as goodwill), over an estimated economic benefit period, generally three to twenty years.
Common Stock	The Board of Directors has authorized the Company to repurchase shares of its common stock. Under this authorization, the Company may finance its share repurchases with available cash reserves or borrowings on its existing line-of-credit. The share repurchase program does not include specific price targets or timetables and may be suspended at any time.
