I was asked to patch up some spots on a customers lawn and some other odd jobs that require some supplies from the home depot. I was thinking of how to bill him. I would go to homedepot, pick up the soil and seeds that i need. (actual price) and then just charge him for my hourly rate? (45.00 an hour) on top of the actual bill from homedepot. Is that what you guys do? Any feedback would help. thanks!
