Giving Credit to Vendors after they file Chapter 11

[btec]

I recently had a customer file Chapter 11. They stuck me with a sizable debt but want to continue busines with me. They are a good company but now expect me to give them credit again because they have a debtors in posession fund and assure priority payment. I've been told legally you have to place them on COD or prepayment. Looking for some assistance and guidance--thanks
