You had plenty of work in 2021.
And there were a couple of customers who drove you crazy with unreasonable demands and abusive behavior.
It might be time to say "goodbye"? Which customers might need to go? How about these:
Never Pleased. These are typically customers with finicky preferences, odd-requests and expectations that you'll do lots of extras for free. They want 80% of your time, but contribute very little revenue.
Abusive. Don't allow customers to be mean, condescending and rude to your employees. It hurts morale. It's disrespectful. Draw a line and let them know you won't tolerate it. Your team will thank you!
Slow Pay. You deserve to be paid fairly and on-time. You shouldn't take on financial risks to take care of clients.
Bad Ethics. Avoid associating your company's reputation with customers who don't match your values. Clients who ask you to cheat, cut corners or break laws should be first to go.
Fill your list with great customers. There are plenty out there!
