Accounting Policies [Abstract]
Nature of Operations	Nature of Operations DNOW Inc. (“DNOW” or the “Company”) is a holding company headquartered in Houston, Texas that was incorporated in Delaware on November 22, 2013. We operate primarily under the DNOW brand along with several affiliated brands operating in local, regional or international markets that are tied to prior acquisitions.

DNOW’s supplier network consists of thousands of vendors in approximately 30 countries.
Basis of Presentation	Basis of Presentation The unaudited consolidated financial information included in this report has been prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”) for interim financial information and Article 10 of the Securities and Exchange Commission (“SEC”) Regulation S-X. All significant intercompany transactions and accounts have been eliminated. Variable interest entities for which the Company is the primary beneficiary are fully consolidated with the equity held by the outside stockholders and their portion of net income (loss) reflected as noncontrolling interest in the accompanying consolidated financial statements. The principles for interim financial information do not require the inclusion of all the information and footnotes required by GAAP for complete financial statements. Therefore, these financial statements should be read in conjunction with the audited consolidated financial statements included in the Company’s most recent Annual Report on Form 10-K. In the opinion of the Company’s management, the consolidated financial statements include all adjustments, which are of a normal recurring nature unless disclosed otherwise, necessary for a fair presentation of the results for the interim periods. The results of operations for the three and nine months ended September 30, 2025, are not necessarily indicative of the results to be expected for the full year.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect reported and contingent amounts of assets and liabilities as of the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates.
Recently Issued Accounting Standards	Recently Issued Accounting Standards In November 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40), which requires more detailed information related to types of expenses in commonly presented captions in income statements. ASU 2024-03 is effective for annual periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The Company is currently assessing the impact of ASU 2024-03 on its consolidated financial statements and its disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740), which requires public companies to expand income tax disclosures. The ASU requires entities to disclose more detailed information in their effective tax rate reconciliation and their cash taxes paid both in the U.S., state and foreign jurisdictions. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, with early adoption permitted for annual financial statements that have not yet been issued. The Company is currently assessing the impact of ASU 2023-09 on its consolidated financial statements and its disclosures. Recently Adopted Accounting Standards In July 2025, the FASB issued ASU 2025-05, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which provides all entities with a practical expedient for estimating expected credit losses on current trade receivables and contract assets under Topic 606. The practical expedient allows entities to assume that current conditions as of the balance sheet date remain unchanged for the remaining life of the asset. ASU 2025-05 is effective for fiscal years beginning after December 15, 2025, with early adoption permitted. The Company early adopted this standard effective September 30, 2025. The adoption of this standard does not have a material impact on its consolidated financial statements. See Note 2 “Revenue” for additional information. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280), which requires enhanced segment disclosures primarily focusing on significant segment expense disclosures for both interim and annual periods. For the fiscal year ended December 31, 2024, the Company adopted this standard using modified retrospective transition method. See Note 9 “Business Segments” for additional information.
Revenue Recognition	The Company’s primary source of revenue is the sale of products for energy and industrial applications based upon purchase orders or contracts with customers. Substantially all of the Company's revenue is recognized at a point in time once the Company has determined that the customer has obtained control over the product. Control is typically deemed to have been transferred to the customer when the product is shipped, delivered or picked up by the customer. The Company does not grant extended payment terms. Revenue is recognized net of any taxes collected from customers, which are subsequently remitted to proper government authorities. Shipping and handling costs for product shipments occur prior to the customer obtaining control of the goods and are recorded in cost of products. The amount of revenue recognized reflects the consideration to which the Company expects to be entitled to receive in exchange for products sold. Revenue is recorded at the transaction price net of estimates of variable consideration, which may include product returns, trade discounts and allowances. The Company accrues for variable consideration using the expected value method. Estimates of variable consideration are included in revenue to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur. See Note 9 “Business Segments” for disaggregation of revenue by reporting segments. The Company believes this disaggregation best depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors.
Remaining Performance Obligations	Remaining Performance Obligations Remaining performance obligations represent the transaction price of firm orders for which work has not been performed on contracts with an original expected duration of more than one year. The Company’s contracts are predominantly short-term in nature with a contract term of one year or less. For those contracts, the Company has utilized the practical expedient in Accounting Standards Codification (“ASC”) Topic 606 exempting the Company from disclosure of the transaction price allocated to remaining performance obligations when the performance obligation is part of a contract that has an original expected duration of one year or less.
Allowance for Credit Losses	Allowance for Credit Losses Allowance for credit losses is estimated based on an evaluation of accounts receivable aging and the related historical loss experience. In accordance with ASU 2025-05, the Company assumes that current conditions as of the balance sheet date will remain unchanged over the remaining life of the asset when estimating expected credit losses on current trade receivables and contract assets. Judgments in the estimate of allowance for credit losses include global economic and business conditions, oil and gas industry and market conditions, customer’s financial conditions and accounts receivable past due. As of September 30, 2025 and December 31, 2024, the allowance for credit losses totaled $14 million and $15 million, respectively.
Contract Assets and Liabilities	Contract Assets and Liabilities Contract assets primarily consist of retainage amounts held as a form of security by customers until the Company satisfies its remaining performance obligations. As of September 30, 2025 and December 31, 2024, contract assets were $1 million in both periods and were included in receivables, net in the consolidated balance sheets. The Company generally accounts for the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that the entity otherwise would have recognized is one year or less; however, these expenses are not material. Contract liabilities primarily consist of deferred revenues recorded when customer payments are received or due in advance of satisfying performance obligations, including amounts which are refundable, and other accrued customer liabilities. Revenue recognition is deferred to a future period until the Company completes its obligations contractually agreed with customers. As of September 30, 2025 and December 31, 2024, contract liabilities were $22 million and $31 million, respectively, and were included in accrued liabilities in the consolidated balance sheets. For the nine months ended September 30, 2025, the decrease in contract liabilities was primarily related to recognizing revenue of approximately $24 million that was deferred as of December 31, 2024, partially offset by net current year customer deposits of approximately $15 million.

Disclosure of accounting policy for credit loss on financial instrument measured at amortized cost basis, net investment in lease, off-balance sheet credit exposure, and available-for-sale debt security. Includes, but is not limited to, methodology used to estimate allowance for credit loss, how writeoff of uncollectible amount is recognized, and determination of past due status and nonaccrual status.
