The journey begins
Worklio began with one idea: bring payroll, HR, benefits, insurance, time, and workforce management into one connected experience. The market taught us quickly that payroll was the core connecting compliance, benefits, and workforce data.
- 2017
Worklio is founded
Worklio LLC was established to build that infrastructure for the organizations that serve employers: PEOs, ASOs, payroll service bureaus, and staffing firms. Payroll came first. The complete platform followed on that foundation.
- 2018
First partners live
Worklio's first reseller and beta partners went live on the platform, the start of live operations, real-world learning, and rapid product expansion.
- 2019
A PEO at scale
DecisionHR, a Florida PEO, brought its payroll and HR operations onto Worklio and proved the platform at PEO scale.
- 2020
API-first scale
The infrastructure ran API-first, building out the endpoints behind embedded payroll and partner integrations. A full compliance audit verified the ISO 27001 and ISO 9001 certifications.

A leading PEO chooses Worklio

Independently audited.
ISO/IEC 27001:2022, ISO/IEC 27018:2019, and ISO 9001:2015 certified. SOC 2 Type 2. Controls aligned with HIPAA and PCI DSS.
Hosted on Microsoft Azure, with a 99.9% availability target.
Every module has audited controls: layered access rights, two-factor authentication, and a full audit trail. The certifications describe Worklio's own audited controls, not your company's compliance.
Built for partners, now yours directly.
The engine Worklio built for partners now powers companies directly, from 50 to 50,000+ employees.
That range runs from a 50-person company leaving starter tools to enterprises running multi-entity, multi-state payroll.
One platform, one employee record.
Payroll, tax, HR, time, and benefits administration run on one 50-state engine. Worklio has 30 modules on one employee record, so changes flow to payroll, time, benefits, and reporting automatically.
Modules can be added at any time, because the data is already in place. Approve once: hours flow in from time tracking, deductions from benefits, and every pay run posts taxes, filings, comp premiums, and the general ledger automatically.
Every state, every locality.
Federal, state, and local tax calculation and filing, including reciprocity and multi-state work.
Payroll covers all 50 states and Puerto Rico, with city, county, and school district taxes included. Worklio files year-end W-2 and 1099-NEC forms automatically.
Named people, not a queue.
A named implementation lead moves your employees, YTD wages, tax IDs, and deductions. They run one or more parallel payrolls beside your current provider, matched to the cent, before you go live. Your team gets training and employees get self-service invites.
After go-live, a dedicated account manager stays with you for as long as you are a customer.
Go-live is usually timed to the start of a quarter or year. Companies with 50 to 500 employees go live fastest, 500 to 5,000 plan around a quarter start, and 5,000+ roll out in phases, entity by entity. Your timeline depends on entities, states, integrations, and data quality.
