The big reason why startups use letters of credit is to give their landlord at their new office space a defacto deposit. It’s basically collateral for the landlord. And so, what the startup will do will have their bank issue a letter of credit may be for $100,000 maybe for $200,000. The bank will segregate that cash out of the startup’s normal operating account, back the letter of credit with that cash, the startup can’t touch it anymore because it’s backing that letter of credit, and then the bank hands over the letter of credit to the landlord.Now, this is preferred because you’re not… You don’t necessarily want to transfer a hundred, two hundred thousand dollars to your landlord. and just hope they’ll get it back for you. Having the bank on your side, having it documented in a letter of credit is much safer for the startup, and it’s much easier logistically.So that’s why startups use a letter of credits. There’re a few other reasons like inventory deposits or things like that, but it’s almost always used to secure new office space.
