Cary:
Define landscaping/maintenance business?
If they cut lawns and look after the flowers etc then this is a large number of very small jobs.
If they do landscaping projects for new construction then this is a whole different story.
I have a couple of nurseries (one wholesale and one retail) as a client but neither do direct landscape/maintenance. Rather than trying to tie in their existing POS it might be more appropriate to switch to something already tied in.
For this company to fit Adagio they must meet the normal standards including at least a full time bookkeeper. If they are a large retail nursery then there may be a fit, otherwise it would take a lot of lawn cutting and/or new home construction to get to the right size.
Give me a call if you'd like to discuss this further.
