Payroll Outsourcing Services

Take the burden of payroll off your shoulders

Managing payroll is a tedious process. With every new hire, your task list—from collecting documents and timesheets to distributing paychecks and tax forms—eats up more of your day. But when you’re hiring temporary workers to boost your productivity, you don’t want the headache of payroll to increase.


ATR International covers all your contractor payroll needs, so you can focus on hitting one business goal after another.

Efficient Payrolling, From Start to Finish


Fill in gaps in your organization without adding to your headcount. We’ll add your contractor to our payroll and act as their employer of record. All your payroll priorities are covered for the entire duration of their assignment:

  • Candidate background and drug screening
  • Employee onboarding and offboarding
  • I-9 compliance (including E-Verify)
  • TN and other foreign worker visa administration
  • Employee benefits
  • Employee direct deposit
  • Year-end W-2 forms
  • Expense reimbursement
  • Weekly payroll processing
  • Daily administrative support


Our team also mitigates co-employment concerns with our comprehensive contractor care program.
