Asset Based Lending is the blanket term for borrowing against receivables and/or inventory: https://en.wikipedia.org/wiki/Asset-based_lending

Factoring ? https://en.wikipedia.org/wiki/Factoring_(finance)

factoring comes in different flavors too. for instance, you can flat-out sell future aaccounts receivables (at a discount, so it has an imputed interest rate), or you can use it as collateral for a loan (with an explicit interest rate).
