Employee Payments Using ISO20022

Hi,

We are using App9 and looking for a solution to handle Employee Payments Using ISO20022.

As of now we do not use HCM module and the Employee Expense system is separated from IFS.

We have requirement to make the employee payments through IFS and using ISO20022. We will be moving IFS Cloud in few years time.

What is the best approach handle this in App9? We have some thoughts around this and have identified few options. But, not sure which is best and simple.

1. Register Employees as Suppliers and integrate with Employee Expense system to create a external supplier invoice.
2. Create Employees as External Payment Recipients and generate a Non-Supplier Payment with a integration. Is there a External File Template for loading a Non-Supplier Payment ?
3. Use the HR module and register Employees in IFS. Use Employee Payments. We do not want a heavy setup HR module that make it complicated.

Thanks
