Has anyone rolled out early access to earned pay for remote teams?

We are a distributed team with people in several countries and some folks have been asking if they can get part of their pay before payday. I am curious if early access to earned wages actually helps with retention or just adds reconciliation work. If you implemented something like this, what were the real operational headaches and how did you resolve them. Also interested in whether it changed the number of ad hoc payroll requests. Thanks.
