Thanks for the feedback. I'm not the OP, and I've been using (suffering through?) the software for over 10 years. It's made a lot of improvements, but also taken some steps back over the years.
I went to cPanel Conf one year and remember talking to one dev and trying to explain how old school cash registers and restaurant POS software systems would allow for GL mapping and export to 3rd party accounting systems and how it would be nice if WHMCS allowed for this at a basic level for accounting needs. I could tell by the expression on his face that he didn't understand why you'd need or want to do such a thing.
I wish WHMCS had some folks working for them that understand the business side of what we, their customers who use the software, have to deal with.
But in the meantime, I'll await the next addons to the marketconnect place, like avocado delivery or Yelp ads.
