I am seeking recommendations for processing 130+/- W2s. My new bookkeeping client used ADP, Decision HR, and an online payroll calculator at different times during 2024. Since I cannot add last year’s payroll data to their new QuickBooks Online account, I need to merge different data sources for each employee and use a W2 processor. I saw SSA has a free service but for only 50 W2s. Plus, I have seen ads for TurboTax (which would be my preference if easy and inexpensive), Tax Bandit, and more. Any thoughts in terms of ease and cost?

Also, they have minimal access and reporting available from previous payroll services. Would I need the Payroll Summary and/or Payroll Register to complete data collection and process the large W2 batch?

Any other guidance would be very appreciated!
