Invoices and credit payments

When we receive a booking from Booking or Airbnb, we enter a credit payment line, so that when the client receives the link from the Client APP, this amount (which has already been paid) does not appear as a pending payment.

When the customer leaves, the invoice (in the customer's name) is taken out, assigning this payment line (the payment entered as credit).

When the actual payment arrives, the administration has to: choose property (in timeshare does not work) open the billing period (with the risk that this means that another invoice is not issued at that time and comes out with wrong date) to modify the form of payment and the date of payment and that counting that we have more than 250 units, an average of 80-90 daily outputs and about 2 minutes per action, is a lot of time spent daily.

The solution would be a list of credits, to ask for more being able to filter by origin, date of entry, date of exit, etc... and with a tic at the beginning to be able to select those that are paid in each remittance and thus 'crush' these credits all at once.
