You can group one or more receivable documents in one bill group.
There are various criteria for grouping documents in a bill group: you can group documents for the same customer, documents with the same due date, documents drawn in the same market, etc.
A bill group consists of one or more documents grouped together to submit to a bank.
A bill group can be submitted for Collection or Discount.
If submitted for Collection, this means that the bank is only responsible for processing the collection of the documents on the due date.
If the bill group is submitted for Discount, this means that the bank will advance the amount of the bill group to the company (or a portion of it, in the case of factoring), that it will take responsibility for collecting on the due dates of the documents that make up the bill group.
A bill group of invoice can be submitted to a financial institution (factor) for risked factoring (here the risk of insolvency is borne by the company) or unrisked factoring (here the risk of insolvency is covered by the factor).
