Invoices for monthly administration fees are issued monthly and will include fees for services performed by Sentinel during the previous month. Typically there will be a separate invoice for each plan that you offer. All invoices are delivered via email and can include multiple recipients. If you would like to update the distribution list for your invoice emails, please contact your account manager.
Calculation of Fees & Back-Up Report
Each month you will be billed for all active employees enrolled in a benefit plus terminated employees with an available balance in their account (FSA and HRA plans). Billing for terminated employees in FSA/HRA will end once their account balance reaches zero or at the end of the plan year, whichever comes first. Billing for terminated employees in a HSA plan will end the month following their termination. You will only be billed once for each employee regardless of the number of plans they have enrolled in. For example, if an employee is enrolled in both Medical FSA and Dependent Care, you would be billed for one participant.
As supporting documentation, Sentinel generates an Employer Billing Report each month that lists all employee accounts included in the calculation of your monthly fee. To access the report go to the Reports tab of the online Employer Portal and locate the Employer Billing Report. To view a full list of the participant accounts, click on the plus sign in the left margin of the Excel window to expand the data displayed.
