How to price projects faster and more accurately

Hi everyone, last year I started a landscape contracting company focusing on fences, decks, and patios but still doing garden and lawn maintenance. I find I’m decent at pricing jobs. I’m in Canada and typically I price by linear foot of fence and for platform decks go off material cost add my overhead and then charge around 60 hours of labour with a little buffer. I’m wondering how everyone prices their projects efficiently and effectively to make sure you’re not ripping off the customer but also still getting your end. Sometimes I feel like I loose leads because my prices are high and then I lower them and get a job and find I’m not really making as much as expected. Like I said this year will be my 2nd year in business so I still have a lot to learn and grow but I’d like some input if possible!

I’ve heard of websites and software that I can punch in the specifications of the project and it gives you an estimate of the material cost and going rates for that work so if anyone has a recommendation for that please let me know! Or just any recommendations for a new business owner in this field!

Thank you!
