As per FFL transfer. If your do what is required by Texas law. You are golden. Just do the minimum effort required that you are not selling to criminal or it straw purchase for a crimanls.

When you sell a firearm, and let us say said firearm was stolen and/or used in crime and was tossed. Let us say, it was traced back to you. FBI can trace it back to original owner if they want to. FBI would visit the original owner and start digging up for answers how and why the gun was used in a crime. The original owner will disclose the the purchaser info and date of sale. It is just a record to prove that a sale transaction took place and simple record of who was the buyer.
Their no need to that BOS is a legal binding document. It is just sales record.
