Have done a mistake related to accounts receivable

I created opening balance for the customers by creating a invoices one day before my my opening balances date and started using the manager software. everything is fine now.
my customers had opening balances and i created some other sales invoices
while receiving money from customers instead of selecting customer credit, i selected accounts receivable and i just typed a customer name and i got many sales invoices of that particular customer and i randomly used to select any invoice and entered the amount.
will that make difference or problem in my accounts later?
