How Multiple-Client Filing Works in OSHA ITA
The main risk is mixing client files, establishment names, and account access. Keep account structure and file validation separate.
Who this is for
Consultants and third-party filers handling more than one client.
Separate clients before you clean data
Keep each client's establishments, files, and ITA account access distinct. Do not combine clients into one working spreadsheet unless the submission workflow requires it.
Watch for inherited account issues
If the prior filer left, the first blocker may be access rather than CSV formatting.
Build a repeatable file checklist
For every client, confirm coverage, account access, establishment names, required fields, validation, export, and OSHA upload confirmation.
