In view of this situation, you can report to the tax bureau, issue a red-ink invoice, and the output is negative. Through the red invoice, the tax bureau will trace the deduction invoice of the other company and why they don't pay your company.
For example, if you give the other party an invoice of 2 million yuan, but the other party doesn't pay the bill and goes to the tax bureau to deduct it, then you can issue an invoice of 2 million yuan in red, which can avoid the company from paying more taxes without receiving the customer's money.
