Answering messages.
Customers like service providers who answer messages faster than you can say "emboss". If you keep people waiting for hours, they will not like this. If they can't reach you for 24+ hours, then you will lose a lot of clients for sure. If you make a mistake on a notarization and then disappear for 24+ hours and don't return emails or calls, then 123notary.com might get a complaint about you. Being fast is being professional, and it pleases your customers.
