Starting balance problem

when i insert the balance of any account receivable the balance be credit not debit
and when i create the suppliers the balance be debit !
any help please

Read the guides - you have to set the starting date and enter the outstanding purchase invoices

This is so that when you receive the payments, there will be invoices to receive the payments against

its the starting balance
not invoices
i have some costumer the account must be debit but when i write the start balance this make it credit

If you read the Set starting balances guide, you will see that you have to enter unpaid purchase invoices in order to setup Supplier debit balances

A debit in Accounts receivable means the customer owes you money, @Ahmed_Gomaa. How can they owe you money if there are no outstanding sales invoices?
