Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the fiscal year ended December 30, 2017, filed on February 27, 2018. There have been no material changes in our significant accounting policies for the three and six months ended June 30, 2018 as compared to the significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended December 30, 2017, with the exception of the adoption of the Financial Accounting Standards Board’s Accounting Standard Update 2014-09 in the first quarter of fiscal 2018. Refer below to “Recently Issued and Adopted Accounting Pronouncements” for further information. The condensed consolidated balance sheet as of December 30, 2017, included herein was derived from the audited financial statements as of that date, but does not include all disclosures including notes required by GAAP on an annual reporting basis. In the opinion of management, the accompanying condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, and are not necessarily indicative of the results of operations to be anticipated for fiscal 2018 or any future period.
Principles of Consolidation	Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and our wholly owned subsidiaries, after elimination of all intercompany balances and transactions. We have prepared the accompanying financial statements in conformity with GAAP.
Fiscal Year-End	Fiscal Year-End We operate and report using a 52 or 53 week fiscal year ending on the Saturday in December closest and prior to December 31. Accordingly, our fiscal quarters end on the Saturday that falls closest to the last day of the third month of each quarter. Both fiscal 2018 and 2017 are reported using a 52 week fiscal year.
Subsequent Events Consideration	Subsequent Events Consideration We consider events or transactions that occur after the balance sheet date but prior to the issuance of the financial statements to provide additional evidence for certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated as required. Please refer to Note 15 - Subsequent Events for further information.
Recently Issued and Adopted Accounting Pronouncements	Recently Issued and Adopted Accounting Pronouncements As an ‘‘emerging growth company’’ under the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, we are electing to not take advantage of the extended transition period afforded by the JOBS Act for the implementation of new or revised accounting standards and, as a result, we will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies. Section 107 of the JOBS Act provides that our decision to not take advantage of the extended transition period for complying with new or revised accounting standards is irrevocable. Recently Adopted Accounting Pronouncements In March 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2018-05, “Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118,” which allowed SEC registrants to record provisional amounts in earnings for the year ended December 30, 2017 due to the complexities involved in accounting for the enactment of the Tax Cut and Jobs Act of 2017 (“the Act”). SEC Staff Accounting Bulletin No. 118 (“SAB No. 118”) was released in December 2017. Refer to Note 10 for further information regarding the provisional amounts recorded as of December 30, 2017 and June 30, 2018. In May 2017, the FASB issued ASU No. 2017-09, “Compensation – Stock Compensation (Topic 718) Scope of Modification Accounting.” The amendments in ASU 2017-09 provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. We adopted ASU 2017-09, using a prospective approach to awards modified on or after the adoption date, in the first quarter of fiscal 2018, and it did not have a significant impact on our financial statement presentation or disclosures. In January 2017, the FASB issued ASU 2017-01, “Business Combinations - Clarifying the Definition of a Business.” This ASU provides further guidance for identifying whether a set of assets and activities is a business by providing a screen outlining that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. We adopted this ASU at the beginning of fiscal 2018 on a prospective basis. Refer to Note 4 for further discussion regarding the business combination we completed in the quarters ended March 31, 2018 and June 30, 2018. In November, 2016, the FASB issued ASU No. 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash.” ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning and ending balances shown on the statement of cash flows. We adopted ASU 2016-18 in the first quarter of fiscal 2018 using a retrospective approach, and it did not have a material impact on our consolidated statement of cash flows. In November 2016, the FASB issued ASU 2016-16, “Intra-Entity Transfers of Assets Other Than Inventory,” which requires entities to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. We adopted this guidance in the first quarter of fiscal 2018 as required. Our adoption of this standard did not have an impact on our consolidated financial statements in the period of adoption. In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230).” ASU 2016-15 amends ASC 230 to add or clarify guidance on the classification of certain cash receipts and payments in the statement of cash flows. We adopted this guidance in the first quarter of fiscal 2018 as required. The updated guidance requires a retrospective transition method to each period presented. The adoption of this ASU did not have a material impact on our consolidated statement of cash flows. In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers,” which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. In August 2015, the FASB issued ASU No. 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date,” which deferred the effective date of ASU 2014-09 by one year to December 15, 2017 for interim and annual reporting periods beginning after that date. Since ASU 2014-09 was issued, several additional ASUs were issued and incorporated within ASC 606 to clarify various elements of the guidance. We adopted ASU 2014-09 and the subsequent ASU’s in the first quarter of fiscal 2018 using the modified retrospective method approach for contracts that were not completed as of December 31, 2017. Results for reporting periods beginning after December 31, 2017 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under Topic 605. We recorded a net decrease to opening accumulated deficit of $0.1 million, net of tax, as of December 31, 2017 due to the cumulative impact of adopting Topic 606, with the impact primarily related to the capitalization of costs for commissions within our business-to-business solutions offering and a portion of revenue recognition for a specific performance obligation within our Payment Solutions offering. Refer to Note 3 for our revenue recognition policies related to the adoption of ASU 2014-09. Recently Issued Accounting Pronouncements In June 2018, the FASB issued ASU No. 2018-07, “Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-based Payment Accounting.” This guidance simplifies the accounting for share-based payments to nonemployees by aligning it with the accounting for share-based payments to employees, with certain exceptions. The guidance is effective for annual periods beginning after December 15, 2018. Early adoption is permitted. When adopting we will apply the new guidance to equity-classified nonemployee awards for which a measurement date has not been established and liability-classified nonemployee awards that have not been settled as of the date of adoption by recognizing a cumulative-effect adjustment to accumulated deficit as of the beginning of the annual period of adoption. We plan to early adopt ASU 2018-07. We do not expect that the adoption of ASU 2018-07 will have a material impact on our consolidated financial position and results of operations. In January 2017, the FASB issued ASU No. 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” To simplify the subsequent measurement of goodwill, the FASB eliminated Step 2 from the goodwill impairment test. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The FASB also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. Therefore, the same impairment assessment applies to all reporting units. An entity is required to disclose the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets. The guidance is effective for us in our annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted. ASU 2017-04 must be applied prospectively. We expect that the future adoption of this update will simplify our measurement of goodwill impairment, if any of our reporting units have a zero or negative carrying value, or would fail Step 1 of the impairment test following the date of adoption. In June 2016, the FASB issued ASU 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” which requires measurement and recognition of expected credit losses for financial assets held. ASU 2016-13 is effective for us in our first quarter of fiscal 2020, and earlier adoption is permitted. The modified-retrospective approach is required for adoption. We are currently evaluating the impact of our pending adoption of ASU 2016-13 on our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842).” The guidance requires an entity to recognize a right-of-use asset and a lease liability for all of its leases with terms of more than 12 months. Recognition, measurement and presentation of expenses will depend on classification as a finance or operating lease. The amendments also require certain quantitative and qualitative disclosures about leasing arrangements. Since ASU 2016-02 was issued, several additional ASUs were issued and incorporated within ASC 842 to clarify various elements of the guidance. The guidance is effective for annual periods beginning after December 15, 2018. Early adoption is permitted. We will adopt the standard using the modified retrospective approach and are still evaluating whether we will elect the practical expedients allowed in the standard. We continue to evaluate the impact of the adoption of ASU 2016-02 on our consolidated financial position and results of operations; however, we expect that the adoption of ASU 2016-02 will primarily impact our real-estate leases.

Recently Issued and Adopted Accounting Pronouncements

As an ‘‘emerging growth company’’ under the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, we are electing to not take advantage of the extended transition period afforded by the JOBS Act for the implementation of new or revised accounting standards and, as a result, we will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies. Section 107 of the JOBS Act provides that our decision to not take advantage of the extended transition period for complying with new or revised accounting standards is irrevocable.

Recently Adopted Accounting Pronouncements

In March 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2018-05, “Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118,” which allowed SEC registrants to record provisional amounts in earnings for the year ended December 30, 2017 due to the complexities involved in accounting for the enactment of the Tax Cut and Jobs Act of 2017 (“the Act”). SEC Staff Accounting Bulletin No. 118 (“SAB No. 118”) was released in December 2017. Refer to Note 10 for further information regarding the provisional amounts recorded as of December 30, 2017 and June 30, 2018.

In May 2017, the FASB issued ASU No. 2017-09, “Compensation – Stock Compensation (Topic 718) Scope of Modification Accounting.” The amendments in ASU 2017-09 provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. We adopted ASU 2017-09, using a prospective approach to awards modified on or after the adoption date, in the first quarter of fiscal 2018, and it did not have a significant impact on our financial statement presentation or disclosures.

In January 2017, the FASB issued ASU 2017-01, “Business Combinations - Clarifying the Definition of a Business.” This ASU provides further guidance for identifying whether a set of assets and activities is a business by providing a screen outlining that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. We adopted this ASU at the beginning of fiscal 2018 on a prospective basis. Refer to Note 4 for further discussion regarding the business combination we completed in the quarters ended March 31, 2018 and June 30, 2018.

In November, 2016, the FASB issued ASU No. 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash.” ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning and ending balances shown on the statement of cash flows. We adopted ASU 2016-18 in the first quarter of fiscal 2018 using a retrospective approach, and it did not have a material impact on our consolidated statement of cash flows.

In November 2016, the FASB issued ASU 2016-16, “Intra-Entity Transfers of Assets Other Than Inventory,” which requires entities to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. We adopted this guidance in the first quarter of fiscal 2018 as required. Our adoption of this standard did not have an impact on our consolidated financial statements in the period of adoption.

In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230).” ASU 2016-15 amends ASC 230 to add or clarify guidance on the classification of certain cash receipts and payments in the statement of cash flows. We adopted this guidance in the first quarter of fiscal 2018 as required. The updated guidance requires a retrospective transition method to each period presented. The adoption of this ASU did not have a material impact on our consolidated statement of cash flows.

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers,” which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. In August 2015, the FASB issued ASU No. 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date,” which deferred the effective date of ASU 2014-09 by one year to December 15, 2017 for interim and annual reporting periods beginning after that date. Since ASU 2014-09 was issued, several additional ASUs were issued and incorporated within ASC 606 to clarify various elements of the guidance. We adopted ASU 2014-09 and the subsequent ASU’s in the first quarter of fiscal 2018 using the modified retrospective method approach for contracts that were not completed as of December 31, 2017. Results for reporting periods beginning after December 31, 2017 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under Topic 605.

We recorded a net decrease to opening accumulated deficit of $0.1 million, net of tax, as of December 31, 2017 due to the cumulative impact of adopting Topic 606, with the impact primarily related to the capitalization of costs for commissions within our business-to-business solutions offering and a portion of revenue recognition for a specific performance obligation within our Payment Solutions offering. Refer to Note 3 for our revenue recognition policies related to the adoption of ASU 2014-09.

Recently Issued Accounting Pronouncements

In June 2018, the FASB issued ASU No. 2018-07, “Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-based Payment Accounting.” This guidance simplifies the accounting for share-based payments to nonemployees by aligning it with the accounting for share-based payments to employees, with certain exceptions. The guidance is effective for annual periods beginning after December 15, 2018. Early adoption is permitted. When adopting we will apply the new guidance to equity-classified nonemployee awards for which a measurement date has not been established and liability-classified nonemployee awards that have not been settled as of the date of adoption by recognizing a cumulative-effect adjustment to accumulated deficit as of the beginning of the annual period of adoption. We plan to early adopt ASU 2018-07. We do not expect that the adoption of ASU 2018-07 will have a material impact on our consolidated financial position and results of operations.

In January 2017, the FASB issued ASU No. 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” To simplify the subsequent measurement of goodwill, the FASB eliminated Step 2 from the goodwill impairment test. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The FASB also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. Therefore, the same impairment assessment applies to all reporting units. An entity is required to disclose the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets. The guidance is effective for us in our annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted. ASU 2017-04 must be applied prospectively. We expect that the future adoption of this update will simplify our measurement of goodwill impairment, if any of our reporting units have a zero or negative carrying value, or would fail Step 1 of the impairment test following the date of adoption.

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” which requires measurement and recognition of expected credit losses for financial assets held. ASU 2016-13 is effective for us in our first quarter of fiscal 2020, and earlier adoption is permitted. The modified-retrospective approach is required for adoption. We are currently evaluating the impact of our pending adoption of ASU 2016-13 on our consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842).” The guidance requires an entity to recognize a right-of-use asset and a lease liability for all of its leases with terms of more than 12 months. Recognition, measurement and presentation of expenses will depend on classification as a finance or operating lease. The amendments also require certain quantitative and qualitative disclosures about leasing arrangements. Since ASU 2016-02 was issued, several additional ASUs were issued and incorporated within ASC 842 to clarify various elements of the guidance. The guidance is effective for annual periods beginning after December 15, 2018. Early adoption is permitted. We will adopt the standard using the modified retrospective approach and are still evaluating whether we will elect the practical expedients allowed in the standard. We continue to evaluate the impact of the adoption of ASU 2016-02 on our consolidated financial position and results of operations; however, we expect that the adoption of ASU 2016-02 will primarily impact our real-estate leases.
