The text outlines Merge's introduction of two new models, Pay Group and Bank Info, to its Unified HRIS API, which aim to enhance payroll management and employee benefits services. The Pay Group model allows companies to categorize employees based on payroll criteria, simplifying the creation of payroll runs, while the Bank Info model facilitates managing employees' bank account details for transactions and payments. These features address customer requests for improved payroll support and enable organizations to perform tasks like purchasing benefits on behalf of employees, linking bank accounts, and regulating pay rates efficiently. Merge encourages users to explore these models through a free account or demo, highlighting its role as an integration platform that manages customer integrations beyond being just a Unified API product.
