Dynamics GP customizations are like tattoos
Customizations in Microsoft Dynamics GP are like tattoos. A few, strategically applied are fine, but they are hard to remove when you change your mind. Plus, you'd better know what you have and where it is.
My wife has a tattoo to commemorate the loss of her sister to ovarian cancer. That's a tough tattoo to argue with. Likewise, for most companies that customize Dynamics GP, the first few usually make pretty good sense. An item gets identified in the implementation stage as a gap and a customization is the best solution. Congratulations on your first tattoo!
