The postal software I use has a built-in Point of Sale program that integrates nicely with the shipping functions and I have been switching from using Quick Books for everything to using the POS and inputting bulk sales data when I close shop at night.
It has the option to print bar codes. I recieved a case of bar code labels this morning and have been spending the last couple hours getting it set up. Still have quite a bit more to do...
ARRRRGGGGHHHHHH!!!
That felt better.
