On March 23, 2004, Company A signed a contract with Company B for a sofa of 500,000 yuan

There is basically no need for commercial acceptance.

If you are talking about a banker's acceptance, the accepting bank should pay you unconditionally, which has nothing to do with the deposit status of Company B.

The drawer of the banker's acceptance draft shall deposit the full amount of the bill with its opening bank before the maturity of the bill. The accepting bank shall pay the bill of exchange on the date of maturity or on the day of sight after the maturity date.

If the acceptance bank refuses to pay due to legal defenses, it shall make a certificate of refusal within 3 days from the next day of receiving the commercial draft, and mail it to the holder's bank together with the bank acceptance draft and transfer it to the holder.

If the drawer of the bank acceptance bank fails to deposit the bill in full on the maturity date of the bill, the accepting bank shall charge interest on the amount of the bill of exchange that has not been paid by the drawer at 5/10,000 per day, in addition to unconditionally paying the bill to the bearer with the bill.

The holder of the bank acceptance bill exceeds the prescribed prompt payment deadline, and loses the right of recourse against its predecessor.

Therefore, if you want to sue, the first payer is the accepting bank, and secondly, you can sue Company B and Company C together to claim joint and several liability!

You can only find people who are directly related to you, and then they can go to the people they want to relate to.

Whether the bill of exchange can be endorsed, and whether there are other agreements between company A and company B. In the end, Company B had to pay for this case, but the procedure was a bit cumbersome.
