I'm in the same boat. I'd consider integrating it in my small business, if I'm able to tie it up to accounting software that records transactions. Also wonder what the fee impact would be over LN for smaller payments, considering the jump in transfer costs.
For lightening integration, I do not think you will need to worry about the fees. It will be off chain and cost is very low. But if you are thinking about main chain transactions then right now BTC network is very congested. For micro payments, it's not worth it.
@k3m, I don't see you are online yet. Waiting for your response once you do.
Cheers,
