Typing up invoices and talking to clients is not as much fun as coding for some people. For others it is more fun. Going to work and &quot;getting away with&quot; questionable habits around client relations is just the flip side of going to work and &quot;getting away with&quot; poor habits around coding rigor.<p>The lazy way to handle the habit is to get someone else to do it...i.e. a partner or a service or an employee or a book keeper or your split personality if you have one [you don&#x27;t].<p>If the clients aren&#x27;t upset, and they&#x27;ll let you know by hiring someone else, then it&#x27;s just a quirk and not worth beating yourself up over.<p>Good luck.
