Great idea John. I'd definately be interested in this.
I was planning to work on a budget app, which would calculate your company budget for the year, and work labour burden, overhead, etc. into estimates and sales orders. It would also show forecast vs. actual at the end of the fiscal year. I believe this would be a great tool for all us landscapers, and others as well.
I'd love to see what you're working on as it progresses, and provide some feedback. I'd also like someone to try what I'm doing as well.
Unfortunately, business is picking up for me and I likely won't have what I want for another 6 months or so.
Keep us updated, and if you're interested I will keep you updated as well.
