Payroll Shack review
Payroll APIs and pay-run tools with a $49 monthly platform fee plus usage charges.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
Payroll Shack provides US and Canadian payroll infrastructure for software platforms, accounting firms, and other integrators. Its REST APIs and MCP tools cover company provisioning, employee records, payroll calculations, pay runs, approvals, and payment status. Employee portals can be white-labeled with custom domains, making the product relevant to small and mid-market teams embedding payroll for multiple client companies. It is less suited to teams seeking a broad, geography-agnostic payroll platform.
Pricing combines a $49 monthly Platform access subscription with usage-based charges. The subscription includes 1,633 API credits each billing period and provides the developer dashboard, company provisioning, REST APIs, MCP tools, and employee portal endpoints. Each successful REST request, MCP tool call, or agentic tool execution costs $0.03 per credit. Additional credits are offered in packs of 25 for $0.75, or in custom amounts. Registration is free, but a paid subscription is required to activate the developer portal and call APIs, so this is not a free API plan. Teams should estimate request volume as well as the fixed subscription when budgeting.
The workflow breadth extends beyond data access: teams can create, calculate, approve, and mark pay runs paid, then use reconciliation and blocker checks to review payroll operations. Employee-facing features include payslips and year-end tax forms. Integrations listed include Claude and Cursor, and the deployment is cloud-based; support channels include email, community, and documentation. Payroll Shack is a fit for integrators that want branded portals and API-driven payroll operations with a visible base price. Teams needing broader payroll coverage or a no-subscription way to call APIs should consider alternatives.
