Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements reflect, in the opinion of management, all adjustments, consisting of normal recurring adjustments and accruals, necessary to present fairly the financial position of the Company as of September 30, 2020 and December 31, 2019, the results of operations and comprehensive income for the three and nine months ended September 30, 2020 and 2019, and cash flows for the nine months ended September 30, 2020 and 2019. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) have been condensed or omitted in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and accompanying Notes included in the Company’s annual report on Form 10-K for the year ended December 31, 2019 filed with the SEC on February 26, 2020, except as discussed in the sections entitled “Allowance for Credit Losses” and “Recently Adopted Authoritative Guidance” below. The Company’s results of operations and comprehensive income for the three and nine months ended September 30, 2020 and cash flows for the nine months ended September 30, 2020 are not necessarily indicative of results that may be expected for the year ending December 31, 2020, or for any future period.
Principles of Consolidation	Principles of Consolidation The Condensed Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
Reclassifications and Adjustments	Reclassifications and AdjustmentsCertain prior-year amounts have been reclassified to conform with current-period presentation.
Use of Estimates	Use of Estimates The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the Company’s Condensed Consolidated Financial Statements and accompanying Notes. Management bases its estimates on historical experience and various other assumptions believed to be reasonable, including any potential impacts arising from the novel coronavirus (“COVID-19”) pandemic. Although these estimates are based on management’s best knowledge of current events and actions that may impact the Company in the future, actual results may be different from the estimates. The Company’s critical accounting policies are those that affect its financial statements materially and involve difficult, subjective or complex judgments by management. As of September 30, 2020, the Company is not aware of any events or circumstances that would require an update to its estimates, judgments, or revisions to the carrying value of its assets or liabilities. Given the ongoing uncertainty surrounding the COVID-19 pandemic, events or circumstances may arise that could result in a change in estimates, judgments, or revisions to the carrying value of the Company’s assets or liabilities.
Segment Reporting	Segment Reporting The Company manages its operations as a single segment for the purposes of assessing performance and making operating decisions. The Company's Chief Operating Decision Maker ("CODM") is its Chief Executive Officer. The CODM allocates resources and evaluates the performance of the Company at the consolidated level using information about its revenues, gross profit, income from operations, and other key financial data. All significant operating decisions are based upon an analysis of the Company as one operating segment, which is the same as its reporting segment.
Allowance for Credit Losses	Allowance for Credit Losses The Company is exposed to credit losses primarily through sales of its products and services, as well as its sales-type leasing arrangements. The Company performs credit evaluations of its customers’ financial condition in order to assess each customer’s ability to pay. These evaluations require significant judgment and are based on a variety of factors including, but not limited to, current economic trends, payment history, and a financial review of the customer. The Company continues to monitor customers’ creditworthiness on an ongoing basis. The Company maintains an allowance for credit losses for accounts receivable, unbilled receivables, and net investment in sales-type leases based on expected credit losses resulting from the inability of its customers to make required payments. The allowance for credit losses is measured using a loss rate method, considering factors such as customers’ credit risk, historical loss experience, current conditions, and forecasts. The allowance for credit losses is measured on a collective (pool) basis by aggregating customer balances with similar risk characteristics. The Company also records a specific allowance based on an analysis of individual past due balances or customer-specific information, such as a decline in creditworthiness or bankruptcy. Actual collection losses may differ from management’s estimates, and such differences could be material to the Company’s financial position and results of operations.
Recently Adopted and Issued Authoritative Guidance	Recently Adopted Authoritative Guidance In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The Company adopted ASU 2018-15 on January 1, 2020 on a prospective basis. The adoption of this guidance did not have a material impact on the Company’s Condensed Consolidated Financial Statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments, that modifies or replaces existing models for trade and other receivables, debt securities, loans, and certain other financial instruments. For instruments measured at amortized cost, including trade and lease receivables, loans, and held-to-maturity debt securities, the standard replaced the current “incurred loss” approach with an “expected loss” model. Entities are required to estimate expected credit losses over the life of the instrument, considering available relevant information about the collectibility of cash flows, including information about past events, current conditions, and reasonable and supportable forecasts. The Company adopted the new standard on January 1, 2020 using the modified retrospective transition method, which resulted in the recognition of an immaterial cumulative-effect adjustment to retained earnings. Recently Issued Authoritative Guidance In August 2020, the FASB issued ASU 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40). The update simplifies the accounting for convertible debt instruments by reducing the number of accounting models and the number of embedded conversion features that could be recognized separately from the primary contract. ASU 2020-06 also enhances transparency and improves disclosures for convertible instruments and earnings per share guidance. This update permits the use of either the modified retrospective or fully retrospective method of transition. ASU 2020-06 will be effective for the Company beginning January 1, 2022. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company is currently evaluating the impact ASU 2020-06 will have on its Condensed Consolidated Financial Statements. There was no other recently issued and effective authoritative guidance that is expected to have a material impact on the Company’s Condensed Consolidated Financial Statements through the reporting date.
Revenue Recognition	Revenue Recognition The Company earns revenues from sales of its products and related services, which are sold in the healthcare industry, its principal market. The Company’s customer arrangements typically include one or more of the following performance obligations: Products. Software-enabled equipment that manages and regulates the storage and dispensing of pharmaceuticals, consumable blister cards and packaging equipment and other medical supplies. Software. On premise or cloud-based subscription solutions that improve medication management and adherence outcomes or enable incremental functionality of the Company’s equipment. Installation. Installation of equipment as integrated systems at customer sites. Post-installation technical support. Phone support, on-site service, parts, and access to unspecified software updates and enhancements, if and when available. Professional services. Other customer services, such as technology-enabled services, training, and consulting.
Net Income (Loss) Per Share	Basic net income per share is computed by dividing net income for the period by the weighted-average number of shares outstanding during the period. In periods of net loss, all potential common shares are anti-dilutive, so diluted net loss per share equals the basic net loss per share. In periods of net income, diluted net income per share is computed by dividing net income for the period by the basic weighted-average number of shares plus any dilutive potential common stock outstanding during the period, using the treasury stock method. Potential common stock includes the effect of outstanding dilutive stock options, restricted stock awards, and restricted stock units, as well as shares the Company could be obligated to issue from its convertible senior notes and warrants, as described in Note 9, Convertible Senior Notes. Any anti-dilutive weighted-average dilutive shares related to stock award plans, convertible senior notes, and warrants are excluded from the computation of the diluted net income per share.
Fair Value Hierarchy	The Company measures its financial instruments at fair value. The Company’s cash and cash equivalents are classified within Level 1 of the fair value hierarchy as they are valued primarily using quoted market prices utilizing market observable inputs. The Company's interest rate swap contracts and credit facilities are classified within Level 2 as the valuation inputs are based on quoted prices or market observable data of similar instruments. The Company's convertible senior notes are classified within Level 2 as the valuation inputs are based on quoted prices in an inactive market on the last day in the reporting period.
Convertible Debt	Convertible debt instruments that may be settled in cash are required to be separated into liability and equity components. The allocation to the liability component is based on the fair value of a similar instrument that does not contain an equity conversion option. Based on this debt-to-equity ratio, debt issuance costs are then allocated to the liability and equity components in a similar manner.

9 Months Ended

Sep. 30, 2020

The accompanying unaudited Condensed Consolidated Financial Statements reflect, in the opinion of management, all adjustments, consisting of normal recurring adjustments and accruals, necessary to present fairly the financial position of the Company as of September 30, 2020 and December 31, 2019, the results of operations and comprehensive income for the three and nine months ended September 30, 2020 and 2019, and cash flows for the nine months ended September 30, 2020 and 2019. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) have been condensed or omitted in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and accompanying Notes included in the Company’s annual report on Form 10-K for the year ended December 31, 2019 filed with the SEC on February 26, 2020, except as discussed in the sections entitled “Allowance for Credit Losses” and “Recently Adopted Authoritative Guidance” below. The Company’s results of operations and comprehensive income for the three and nine months ended September 30, 2020 and cash flows for the nine months ended September 30, 2020 are not necessarily indicative of results that may be expected for the year ending December 31, 2020, or for any future period.

Principles of Consolidation

The Condensed Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

Reclassifications and Adjustments

Reclassifications and AdjustmentsCertain prior-year amounts have been reclassified to conform with current-period presentation.

Use of Estimates

The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the Company’s Condensed Consolidated Financial Statements and accompanying Notes. Management bases its estimates on historical experience and various other assumptions believed to be reasonable, including any potential impacts arising from the novel coronavirus (“COVID-19”) pandemic.

The Company performs credit evaluations of its customers’ financial condition in order to assess each customer’s ability to pay. These evaluations require significant judgment and are based on a variety of factors including, but not limited to, current economic trends, payment history, and a financial review of the customer.

Recently Adopted and Issued Authoritative Guidance

Recently Adopted Authoritative Guidance

In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The Company adopted ASU 2018-15 on January 1, 2020 on a prospective basis. The adoption of this guidance did not have a material impact on the Company’s Condensed Consolidated Financial Statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments, that modifies or replaces existing models for trade and other receivables, debt securities, loans, and certain other financial instruments. For instruments measured at amortized cost, including trade and lease receivables, loans, and held-to-maturity debt securities, the standard replaced the current “incurred loss” approach with an “expected loss” model. Entities are required to estimate expected credit losses over the life of the instrument, considering available relevant information about the collectibility of cash flows, including information about past events, current conditions, and reasonable and supportable forecasts. The Company adopted the new standard on January 1, 2020 using the modified retrospective transition method, which resulted in the recognition of an immaterial cumulative-effect adjustment to retained earnings.

Recently Issued Authoritative Guidance

In August 2020, the FASB issued ASU 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40). The update simplifies the accounting for convertible debt instruments by reducing the number of accounting models and the number of embedded conversion features that could be recognized separately from the primary contract. ASU 2020-06 also enhances transparency and improves

disclosures for convertible instruments and earnings per share guidance. This update permits the use of either the modified retrospective or fully retrospective method of transition. ASU 2020-06 will be effective for the Company beginning January 1, 2022. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company is currently evaluating the impact ASU 2020-06 will have on its Condensed Consolidated Financial Statements.

There was no other recently issued and effective authoritative guidance that is expected to have a material impact on the Company’s Condensed Consolidated Financial Statements through the reporting date.

Revenue Recognition

The Company earns revenues from sales of its products and related services, which are sold in the healthcare industry, its principal market. The Company’s customer arrangements typically include one or more of the following performance obligations:

Products. Software-enabled equipment that manages and regulates the storage and dispensing of pharmaceuticals, consumable blister cards and packaging equipment and other medical supplies.

Software. On premise or cloud-based subscription solutions that improve medication management and adherence outcomes or enable incremental functionality of the Company’s equipment.

Installation. Installation of equipment as integrated systems at customer sites.

Post-installation technical support. Phone support, on-site service, parts, and access to unspecified software updates and enhancements, if and when available.

Professional services. Other customer services, such as technology-enabled services, training, and consulting.

Net Income (Loss) Per Share

Basic net income per share is computed by dividing net income for the period by the weighted-average number of shares outstanding during the period. In periods of net loss, all potential common shares are anti-dilutive, so diluted net loss per share equals the basic net loss per share. In periods of net income, diluted net income per share is computed by dividing net income for the period by the basic weighted-average number of shares plus any dilutive potential common stock outstanding during the period, using the treasury stock method. Potential common stock includes the effect of outstanding dilutive stock options, restricted stock awards, and restricted stock units, as well as shares the Company could be obligated to issue from its convertible senior notes and warrants, as described in Note 9, Convertible Senior Notes. Any anti-dilutive weighted-average dilutive shares related to stock award plans, convertible senior notes, and warrants are excluded from the computation of the diluted net income per share.

Fair Value Hierarchy

The Company measures its financial instruments at fair value. The Company’s cash and cash equivalents are classified within Level 1 of the fair value hierarchy as they are valued primarily using quoted market prices utilizing market observable inputs. The Company's interest rate swap contracts and credit facilities are classified within Level 2 as the valuation inputs are based on quoted prices or market observable data of similar instruments. The Company's convertible senior notes are classified within Level 2 as the valuation inputs are based on quoted prices in an inactive market on the last day in the reporting period.

Convertible Debt

Convertible debt instruments that may be settled in cash are required to be separated into liability and equity components. The allocation to the liability component is based on the fair value of a similar instrument that does not contain an equity conversion option. Based on this debt-to-equity ratio, debt issuance costs are then allocated to the liability and equity components in a similar manner.
