Payroll Integrations

What Payroll Integrations does

Payroll Integrations Inc. is a San Diego-based software company founded around 2019 that operates an API-first B2B connectivity platform linking payroll systems to employee benefit providers. Its core technology is a direct, system-to-system API platform using token-based authentication (OAuth or API keys) — explicitly avoiding screen scraping or credential storage — with SOC 2 Type II certification and 99.9% uptime. The platform connects 200+ payroll providers (including ADP, Paychex, QuickBooks Online, UKG, and Workday) with 75+ 401(k) recordkeepers (including Fidelity, Empower, Transamerica, Principal, John Hancock, Voya, Vanguard, Charles Schwab, and Wells Fargo), automating the transmission of contributions, census data, deferral changes, loan repayments, and eligibility updates that previously required manual file uploads.

The product portfolio comprises four integrated modules — Retirement & 401(k), Tax-Advantaged Accounts (HSAs), Flexible Benefits Management, and Compliance & Reporting — built on the same underlying API platform. Payroll Integrations also publishes an annual Employee Financial Wellness Report as a thought-leadership and demand-generation asset.

The business model is subscription-based recurring revenue from B2B channel partnerships rather than direct consumer sales. The company monetizes by providing connectivity as an embedded or white-label layer to payroll providers, recordkeepers, and third-party administrators (TPAs); pricing is quote-based and not publicly disclosed, with no long-term contracts or upfront fees required. Distribution is exclusively through B2B partnerships, the ADP Marketplace, and a regional direct sales team (Eastern, Mountain, Western U.S.). The company is backed by Arthur Ventures following a $20 million Series A in 2023, serves over 5,000 employer clients covering more than one million employees, and was ranked in the top 15% of the 2025 Inc. 5000.

Direct peers

• Stax.ai: Stax.ai is a TPA-focused retirement platform that integrates directly with Payroll Integrations to automate payroll and census data collection. As an integration partner and adjacent workflow provider for third-party administrators, it is the closest comparable in product and customer overlap.
• Atomic: Atomic provides payroll connectivity APIs that link payroll systems to financial applications. Like Payroll Integrations, it offers API-first infrastructure to bridge payroll providers with downstream apps, targeting similar fintech and benefits-tech customers.
• Pinwheel: Pinwheel operates a payroll API platform enabling apps to access direct-deposit switch, income, and employment data from payroll providers. It is highly comparable as an API-first payroll connectivity layer serving consumer finance and benefits use cases.
• Finch: Finch is a unified API for employer systems (payroll, HRIS, benefits) that lets applications read and write data across providers. It competes head-to-head as infrastructure for benefits and HR applications connecting to multiple payroll systems.

Emerging players

• Vestwell: Vestwell is a digital retirement plan recordkeeping platform serving employers and advisors, with API integrations to payroll providers. It overlaps with Payroll Integrations on the retirement-side and competes for the same employer benefits automation budgets.
• Human Interest: Human Interest is a tech-enabled 401(k) provider for SMBs with built-in payroll integrations. It addresses similar pain points (payroll-to-retirement data automation) but as a recordkeeper rather than a pure connectivity layer.
• PlanSource: PlanSource is a benefits administration and management platform that integrates with payroll and carrier systems. While broader in scope, it overlaps in automating payroll-to-benefits data flow for employers.

Broad incumbents

• ADP (ADP Marketplace / ADP TotalSource): ADP is the largest US payroll and HR provider and operates ADP Marketplace, where Payroll Integrations is listed. ADP is both a partner and a potential competitor if it expands native retirement integrations.
• Workday: Workday is a leading enterprise HR and payroll platform and a listed integration partner of Payroll Integrations. As a broad incumbent with the ability to build native benefits connectivity, it represents a comparable strategic option in the same workflows.

Others

• Plaid: Plaid is an API-first financial data connectivity platform. While focused on consumer banking rather than payroll-to-benefits, it is thematically comparable as a developer-first connectivity layer enabling downstream applications.
