Friends Life has revealed the details of its online auto-enrolment portal for employers.
The tool will collect information from employers' payroll and HR systems and determine what pension arrangements and contributions are necessary for each employee.
The hub can automatically calculate which employees are eligible for auto-enrolment and re-enrol opted-out members after three years.
It also allows ineligible employees to voluntarily opt in online, and provides online access to information for employers and staff.
The hub can produce analysis and management information to help employees meet their reporting requirements.
Colin Williams, managing director of corporate benefits at Friends Life, said: "Making auto-enrolment work will require employers to review their employee base for eligibility and contribution levels at every pay date.
"This will be a complex task, particularly for companies with large numbers of employees, or who pay wages weekly, have multiple payroll and HR systems or which have employees whose pay varies."
