Any suggestions? Year after year I get more and more frustrated with people. I bill out monthly and I give them 20 days to pay. About 25% of my customers pay within week. About 50% of them pay but are always at least 10 days late and the other 25% need a reminder on the following invoice to pay. I always get my money but its slow. I utilize online pay but that really hasn't helped speed things up. I highlight the due date on the invoice and that doesn't help. I tack on a late fee and they don't pay it. Any suggestions on how to speed them up?
