How to edit the reminder message?

Hello, your company has accumulated RMB owed to our company. For the sake of our long-term cooperation and avoiding some unnecessary influences, please settle the account as soon as possible.

This series should be "elastic". Paying off debts is a long and arduous task. Debt collectors should have perseverance, never miss any opportunity when they see a glimmer of light, and at the same time learn to complain, not to sympathize with each other, but to let them sympathize with themselves.
