Detritus I think for now what you need is a faster way to run your business without any pending work just because you want to tell your employees how to trade bitcoin tutorials. You can do the advice from franky1, because after all the implementation will not be much different. Rather than spending time teaching them about Bitcoin, it might be easier to understand with hands-on training.
I will summarize it into stages according to what franky1 said.
have them book mark a bitcoin price calculator site.
so that when selling goods for $xx.. they can calculate how much btc that totals and ask customer to pay
get your employees to bookmark the blockchain.info/btc/[your address]
on their phone so they can watch for new payments,
the site also displays a QR code for that address the employee can show to customers
.
then the employee just watches for the payment to show in on the page
you could also then code up your own app that automates all of this
