Payroll calculation APIs
Supports gross-to-net workflows, deduction logic, and pay component modeling via consistent API contracts.
Embedded payroll infrastructure for modern SaaS and fintech platforms.
Add payroll to your product without becoming a payroll company
Embedded payroll infrastructure for modern SaaS and fintech platforms — APIs for calculations, employee records, tax workflows, and pay-run orchestration.
The problem
The painful workflow
Product teams stall when payroll scope expands into tax, filings, and money movement
Building payroll in-house pulls engineering away from core product for 12–18 months
Partner APIs are fragmented across calculations, employee data, and pay-run state
Compliance evidence for audits lives in spreadsheets and email threads
Every new customer geography multiplies integration and ops work
The solution
What Asphero automates
Asphero is building API-first payroll infrastructure so platforms can offer payroll without owning the full compliance stack.
Employee & pay-run records
Organizes employee profiles, pay schedules, and pay-run state so your product stays the system of record for UX.
Tax workflow orchestration
Assists with tax parameter updates, withholding workflows, and evidence collection for operational review.
Pay-run orchestration
Coordinates validation, approval steps, and funding readiness signals before disbursement.
AI agents
AI agents help monitor missing setup data, flag configuration gaps, and surface exceptions before pay day.
Why this matters — Ship payroll faster, reduce ops drag, and keep your team focused on product — not rebuilding payroll infrastructure.
