How to write a slogan about project payment arrears?

The writing is as follows:

1. Operate with integrity, keep promises and pay! Defaulting in project payment will harm others and benefit oneself.

2. Build a better future and jointly safeguard legitimate rights and interests. Do not default on project payments and ensure the smooth operation of the supply chain.

3. Fair trade, mutual benefit, please pay the project payment you promised in a timely manner. Breach of contract will affect corporate reputation and long-term development.
