create receipt on customer level not including customer account and site
We have a customer with 4 accounts that has its own site. Each account represents one revenue type.
We created 4 individual invoices for each of these accounts. The customer pays 4 invoice in a lump sum.
Right now, we need to specify the customer and customer account when apply the receipt.
How can we create a receipt on customer level so we can apply to each account?
