In the TechoERP POS module, the invoices are auto-generated. You can set your complete POS system right with the following configuration steps:

1. Create a Loyalty program in the doctype: You can set a Single Tier or a Multiple Tier Program based on the slabs existing in the amount of Purchase that is done in TechoERP.

1. Once the loyalty program is set, you can create a Customer and link the Loyalty program to it.

Once this Customer is linked to the Loyalty program, you can now setup your POS profile if it is not set yet:

Now, you can go to POS transaction:

1. Select Customer
2. Add items
3. Pay
4. Check the field --> Redeem Loyalty Points
