*Off-cycle, new-hire, and termination payments are processed on an as-needed basis by your advisor, or self-processed by the business owner or designee. There are certain situations where off-cycle payrolls cannot be run, such as for employees who were just hired inside of an existing pay period. Ask your payroll advisor for more details if you have questions. **Direct deposit speed is determined by a number of factors, and is outside of the control of Portside. Gusto will determine which direct deposit speed your organization is eligible for. Speeds range from a 4-day lead time to same-day direct deposit.
