This is the same as a payment, but the user is the payee instead of the payer. I used a different relation than payment because i do not know any other way to encode the constraint that only invoices can have a collection, while expenses have only payments. Besides the name and the fact that they are related to invoices, a collection is pretty much the same as a payment. |
