I developed a high interest in Bitcoin lately want to accept Bitcoin for my sales and servicing company, am already working with a programmer to develop software or an application that will aid my transactions using the Bitcoin lightning network.
As the saying goes, no man is an island of knowledge, so I shared my story to get suggestions from this noble forum.
I think that you might be able to get away just using regular network if you merchandise is not considered micro transaction, and i think there a lot of providers out there that provide crypto specific machines that are made to make paying easier by just scanning and depending on where you live it might be better than just paying a programmer to make an app that can have some flaws in it
