Open Enrollment Best Practices for Brokers: Setting up Payroll & Benefits Integrations

Managing open enrollment is complex enough; but when you add payroll systems, carriers, and TPAs into the mix, things can quickly become overwhelming.

That’s where 3rd party apps and integrations come in.

For brokers, effectively managing integrations during open enrollment is critical to ensuring accurate data, smooth workflows, and a successful enrollment experience for clients.

In this part of our Open Enrollment series, we’ll cover best practices for working with payroll and benefits integrations during enrollment.

Why Integrations Matter During Open Enrollment

Integrations connect Employee Navigator with payroll providers, insurance carriers, and TPAs, allowing employee data to sync automatically across systems.

During open enrollment, integrations help brokers:

• Eliminate duplicate data entry
• Reduce errors between systems
• Keep payroll and benefits aligned
• Streamline workflows for HR teams

When executed correctly, integrations are a key driver of efficiency and accuracy during the busiest time of year.

Carrier & TPA Integration Best Practices

Each carrier and third-party administrator (TPA) may have different requirements during open enrollment. Preparing ahead of time helps avoid delays and errors.

Review Carrier-Specific Open Enrollment Requirements

Before enrollment begins:

• Check each carrier’s open enrollment guidelines
• Look for blackout periods or submission restrictions
• Confirm whether a census or additional data is required

Understanding these requirements upfront helps prevent last-minute surprises.

Renew Plans Instead of Rebuilding

Rebuilding plans from scratch can be time-consuming and increase the risk of errors.

Whenever possible:

• Use plan renewal features
• Carry over existing carrier structures
• Minimize manual setup work

This approach saves time and ensures consistency across plan years.

Audit Employee Demographic Data

Incomplete or inaccurate employee data is one of the most common causes of integration issues.

Before open enrollment:

• Run reports to identify missing demographic fields
• Confirm required data is complete for all employees
• Ensure records meet integration requirements

Clean data upfront leads to smoother syncing across systems.

Payroll Integration Best Practices

Payroll integrations play a critical role in ensuring accurate deductions and a smooth transition into the new plan year. Here are some suggestions from the Employee Navigator team that can help your payroll integrations go seamlessly.

Confirm Deduction Code Mapping

Deduction codes must be aligned between systems to ensure accurate payroll processing.

Before enrollment:

• Verify whether deduction codes have changed from the prior year
• Confirm mappings with your client’s payroll provider
• Avoid assumptions and always validate

Set Up Deduction Codes for New Plans

If new benefit plans are being introduced:

• Create corresponding deduction codes
• Ensure they are properly configured before enrollment begins
• Align codes with payroll system requirements

Proper setup prevents downstream payroll issues.

Choose the Right Send Deductions Date

The Send Deductions Date determines when enrollment data is transmitted to payroll, and timing is critical.

To ensure accuracy, this date should:

• Occur after the final payroll of the previous plan year
• Be at least one day after open enrollment closeout
• Fall before the first payroll processing date of the new plan year

Example Scenario

For a bi-weekly payroll schedule:

• First pay date of the new plan year: June 14
• Payroll is processed: June 11
• Open enrollment close date: June 1

Recommended Send Date: June 2

This gives the client time to review deductions before payroll is processed.

Encourage clients to review deductions carefully after they are sent to ensure accuracy before processing payroll.

Avoid Accidental Employee Terminations

Integration issues can sometimes lead to unintended consequences, like accidental terminations.

For example:

• Employees moving between departments or locations may shift payroll entities
• Without proper communication, this can trigger a termination event

To prevent this:

• Ensure HR communicates employee changes clearly
• Verify how payroll handles transfers vs. terminations
• Keep employees active in Employee Navigator when appropriate

This helps avoid coverage gaps and ensures benefits remain intact.

Help Your Clients Run a Smoother Open Enrollment

Managing 3rd party integrations during open enrollment may seem complex, but with the right preparation, brokers can significantly reduce errors and improve efficiency.

By focusing on:

• Clean and complete data
• Proper payroll setup
• Carrier-specific requirements
• Clear communication with clients

You can help ensure a seamless enrollment experience across systems.

Once integrations are set up and running, the next step is managing the enrollment experience itself.
