No. Employers have the option of entering member enrollment, member maintenance, and wage and contribution information directly into the ERM application; this method is most likely ideal for smaller employers. For employers with a large number of employees, bulk upload may be the most efficient option; this will require employers to develop a file. The data required for entry is the same, regardless of whether it is submitted directly online or via file upload.
Employers may choose to only develop a bulk upload file for reporting wages and contributions, and enter member enrollment and member maintenance information directly into ERM. Also, employers may choose to develop all three bulk upload files. Files must meet the specifications dictated by INPRS which can be found here.
