U.S. Commerce-as-a-Service: Market Overview

The U.S. commerce-as-a-service market, covering hosted storefront platforms, order management, payments orchestration and tax engines sold on subscription, reached USD 48.6 billion in 2024 and is forecast to reach USD 97.5 billion by 2032. Private enterprise has led this expansion, with Shopify, BigCommerce and Salesforce Commerce Cloud building the platform layer without federal industrial programmes. Government's role is indirect, setting the tax, consumer disclosure and customs rules that determine which functions merchants buy as services rather than build in-house.

Policy has shaped the market's current form most visibly through the 2018 Supreme Court decision in South Dakota v. Wayfair, Inc., which established economic nexus for remote sales tax collection and pushed merchants toward platforms with embedded tax calculation. Federal procurement is a smaller, distinct channel, with agencies buying commerce services through General Services Administration schedules under the Federal Acquisition Regulation. Direct public-sector spending therefore remains marginal, and private merchant subscriptions account for most revenue.

Policy-Driven Growth in U.S. Commerce-as-a-Service

Three mechanisms drive demand. First, the INFORM Consumers Act, enacted in December 2022 and enforced by the Federal Trade Commission since June 27, 2023, requires high-volume third-party sellers with 200 or more discrete sales and USD 5,000 in revenue within twelve months to verify identity and bank details. Merchants meet this duty through platform-native verification modules, converting a legal obligation into recurring software purchases.

Second, post-Wayfair economic nexus thresholds in most states, typically USD 100,000 in sales or 200 transactions, oblige remote sellers to register and remit state sales tax, driving subscriptions to automated tax engines such as Avalara integrations. Third, the Small Business Administration's 7(a) loan programme, with a maximum loan amount of USD 5 million, finances the digital capital expenditure that small merchants use to adopt commerce platforms. Each mechanism turns a statutory duty into a repeatable software purchase.

Regulatory Barriers and Compliance Costs

Cross-border merchants face the largest new cost from U.S. Customs and Border Protection, which administers Section 321 of the Tariff Act of 1930. Following the executive order suspending duty-free de minimis treatment effective August 29, 2025, each cross-border parcel requires formal entry, duty assessment and a customs bond. Platforms must now integrate harmonised tariff classification tools, raising per-shipment processing costs for smaller sellers.

Data privacy obligations add recurring expense. The California Consumer Privacy Act, enforced by the California Privacy Protection Agency, requires businesses to honour opt-out preference signals, publish notices and conduct risk assessments. Penalties reach USD 7,988 per intentional violation after the 2025 inflation adjustment, so merchants selling into California must fund consent tooling and compliance audits.

Policy-Created Opportunities in the United States

Foreign-Trade Zones create the first major opportunity. The Foreign-Trade Zones Board, housed within the Department of Commerce and governed by 19 U.S.C. 81a, authorises bonded facilities where imported goods are stored duty-deferred. As duty-free entry ends, zone-based fulfilment operators gain a compliance-led route for cross-border merchants, creating demand for commerce software that tracks zone inventory and entries.

The federal procurement channel offers a second opportunity. GSA Multiple Award Schedules let agencies buy commerce services from pre-vetted vendors under the Federal Acquisition Regulation. Vendors listed on these schedules gain access to agency purchasing portals, and small business set-asides administered through the Small Business Administration favour qualifying providers.

Regulatory and Policy Environment

The principal federal statute governing marketplace commerce is the INFORM Consumers Act, enacted as part of the Consolidated Appropriations Act, 2023 (Public Law 117-328) and enforced by the Federal Trade Commission. Key compliance requirements include collecting and verifying high-volume seller information, disclosing seller names and contact details on product listings, and providing a clear mechanism for consumers to report suspicious activity. Customs obligations sit under Section 321 of the Tariff Act of 1930, administered by U.S. Customs and Border Protection.

Upcoming changes include updated California Consumer Privacy Act regulations, taking effect January 1, 2026, with automated decision-making technology obligations phasing in from 2027. Against European peers, the U.S. framework is fragmented: Article 30 of the Digital Services Act has required online marketplaces to trace traders since 17 February 2024, and Council Directive (EU) 2021/514 (DAC7) requires platform operators to report seller income annually. The United States relies on state-by-state rules rather than a single federal traceability regime.

Long-Term Policy Outlook for U.S. Commerce-as-a-Service

By 2032, tariff policy will remain the largest swing factor. Section 321 duty-free treatment is suspended, and whether Congress codifies a permanent threshold will determine whether cross-border merchants absorb duty-paying logistics or shift volume to domestic fulfilment nodes. Commerce platforms with integrated landed-cost calculators and bonded-warehouse connectors will capture that reallocation.

Federal marketplace tax legislation is the second structural variable. The Marketplace Fairness Act, which would extend state sales tax collection to all sellers under a federal framework, passed the Senate in 2013 but never became law. Meanwhile, state privacy statutes modelled on the CCPA are spreading, and expanding compliance requirements will push smaller merchants toward managed platforms with privacy tooling built in, sustaining subscription growth through 2032.
