I finance the larger jobs...if needed. I don't charge interest but do charge a set rate based on how much they want to finance. Usually we are so booked out that I receive a deposit the day they accept the job. Then I get another payment a month later....so before I have even set foot on the property I have received two payments. Then we do the job and we invoice them the remainder on Net30. Thats typically three payments in about three months. I usually don't go much over a 3 month payment period unless its a unique situation.
This summer we were booked out to full capacity. I was approached by a large management firm that managed large commercial properties. The properties are each run on their own budget and they were tapped for the year and could not spend anymore on tree removals. I suggested that we do the work in the summer and they can all pay starting in January. I didn't need the money in the summer because cash flow was excellent. Now, I am sitting here in January with 7,500 a month coming in for the next three months. It makes it easier to stay in on theses wet days.....but does not help if you need that money for a large purchase of equipment.
I actually like to offer the payment plan to people...I feel it helps with the large cost burden of tree work. Just means the business has to be good at money management. Which can be hard at times.
