TriNet does not offer this dedicated model for all clients.  - **Superior Integrations**: ADP connects with hundreds of third-party applications (financial wellness, productivity, etc.) for a fully integrated ecosystem, whereas TriNet offers limited third-party connectivity.  - **Legal Defense Benefit**: ADP TotalSource includes a Legal Defense Benefit to help mitigate the potential costs of defending employee lawsuits. TriNet does not offer this specific financial protection benefit.2  - **Data-Driven Insights**: Aggregated and anonymized HR and pay data benchmarks from ADP’s U.S. client base of over 39 million employees to guide compensation and retention strategies, a dataset scale TriNet cannot match.  - **Custom Reporting**: ADP offers a custom report builder with 24/7 access to 300+ pre-built reports; TriNet’s reporting capabilities are less flexible.  ### Is it easy to switch to ADP from my current provider? We can support your switch at any time, so you don't have to wait for a quarter or year-end to access the benefits of ADP. If you're already processing payroll, having your employee data and required documents ready will help ensure a smooth and efficient transition.
