I'm new to Odoo but we are implementing Odoo 8 and I have a question regarding customer payments and how to best register them.

Here in Sweden we get a daily lump sum from an external bank service called BankGiro into our bank account. This lump sum contains payments from multiple customers and each customer could have paid multiple invoices. (I get a list of all invoices paid, that's included in this sum)

The way I'm used to processing payments is: I have a list of all outstanding invoices in our ERP, and I mark all invoices that's included in the lum sum that arrived for the day. When I have marked all invoices as paid, I then post the journal.

Posting the journal means that the sum of all these payments hit our bank ledger, not each individual paid invoice. When I look at the bank ledger in Odoo I would like to see the lump sum that matches the actual lump sum in our bank account.

Is there a way to group payments from multiple customers so that it hits the ledger as one big sum?

Is there a module that does this kind of thing?

Any help is very much appreciated
