When i use the batch create function for starting balance of customers. the start balance appear in the credit side
How can i do that without using unpaid invoice
You simply cannot. If you don’t want to enter many invoices you can enter a cumulative one for each client/supplier. But I don’t think it’s a good idea. You can batch create the invoices which is a lot better.
Read the Guide: Set starting balances for customers | Manager. You will notice that the field labeled as Starting balance is only for available credit. It is not meant for unpaid invoices.
then what should we do for starting balances?
Follow the Guide linked to in post #3. If you have a specific question, ask it.
