Opening balance is the balance contact (customer or supplier) have at the beginning of using the software.
Suppose you’re shifting the data from another software to Jadid Khata POS & ERP then the opening balance of the contact will be the balance amount which the contact has to pay/receive to/from you.
Opening balance for customer = Amount the customer has to pay
Opening balance for supplier = Amount you have to pay to the supplier.
You can add an opening balance when adding/editing the supplier or customer. In the add contact screen, you will find the opening balance field.
To view the opening balance of contact, go to List Supplier/customer, go to view, and on the view page, you will find the opening balance & opening balance due.

Adding payment of the opening balance is the same as any other payments. Go to list Customer/Supplier -> Actions -> Pay.
It will open a popup modal where you can enter the payment amount.
