Summary

Synergetic does not have a specific process for the purchasing of additional leave.  This article explains a work around so that the additional liability is accounted for. 

End Result

The employee will have additional leave that they can use as required. 

Method

These steps are a workaround so that this can be record in your Synergetic System

1. Create a Liability GL Code ( You would then need a Sub-GL Code for each employee that is purchasing Leave)
    
2. Create a Deduction Pay code that links to the Liability GL code -This would then display on Payslip if Display on Payslip option is selected
    
3. As this is not an accrued amount of leave but a "purchase" you would then manually add the amount of purchased leave to their leave balance, alternatively you could create a new leave code to add it to, to keep the amounts separate.
    
4. When the employee takes the leave, you pay if from the Liability GL code in order to reduce the liability. 

Considerations

If an employee no longer wants to deduct additional leave or decides they don't want to take the leave, they can be paid back directly from the liability GL as well.
