# Pool Types

## Revolving Credit Line

This is a common credit product that approves the borrower for a certain credit limit. The borrower can borrow money and repay it, repeatedly, as long as they stay under the credit limit and make timely payments.

## Receivable-backed Credit Line

The borrower is granted a credit line, but they must present a receivable for each borrowing transaction. This receivable must first be approved. Once approved, an advance rate (which is less than 100%) is applied to the receivable amount to determine how much the borrower can borrow using this receivable. This additional amount is then added to the borrower's available credit.

## Receivable Factoring Credit

The borrower can factor a receivable by receiving an advance payment, which is a percentage of the invoice amount.
