how many of you when quoting/billing use a monthly price instead of a per visit price? I'm really starting to like the idea of just saying "It'll be $120/month for your lawn." i think its a little more professional; It would also help people stop thinking along the lines of weekly or biweekly.. and about a straight monthly price. (i get alot of biweekly, crap like that) so how many of you do this? has anyone tried it and not liked it/had bad results? any thoughts?
