To answer your question, no we do not accept credit cards at this time. Most of our accounts are lawn maintenance right now.
If our business expands well into fertilization, we may consider adding that payment option.
I do think anyone heavy into the landscaping end, should accept credit cards.
BTW, you mention the other forum. 95% of the member there are members here too. There's just not much to search over there, so of course the search feature is not going to be mentioned.
Hang around, you'll learn something here too. With a lot more activity here, it's bound to not be as sugary sweet, but it's the real world, and you'll find a lot of helpful members here.
