Identify the essentials to stay running. If it’s a non-essential bill (e.g. cable TV for your customer lobby), get rid of it if there’s no contractual obligation to keep it. And even if there’s a contract, see if you can end it early at no cost or a small termination fee.
For non-negotiable essential expenses (e.g. utilities), see if you can switch to a cheaper provider or plan.
As for your suppliers and other bills, approach each one and try to renegotiate something you can afford.
If it looks like there’s no way to pay everything, you may want to consult with a bankruptcy lawyer. Millions of business owners will do so because of the pandemic. Note that bankruptcy doesn’t necessarily mean the end of your company. There are different types of bankruptcy -- one to reorganize for continuing operations and another to liquidate.
