There is no customer loyalty out here. If someone beats your price by $25 bucks you are out of here.
That really isn't true. This is why there are successful tree services, and so many that are not. The successful companies do excellent work, they are market competitive, and their customers recognize that they are getting good value. Admittedly, you cannot count on customers for "loyalty", but you can bet that they will be willing to stick with the service provider that gives them what they are wanting.
There are many different markets, and you need to understand what market you are pursuing. If you are catering to the market that only wants the lowest price, then you can expect to be sold out quickly by all your customers. If your customers expect a good job done with a reasonably low price, then the price shoppers will be a part of your market, but not a major part. If you are only selling elite service to exclusive customers, the low-price tree services won't even get considered because their trucks are rusty and dented. Conversely, the elite services will be wasting a lot of time on high bids to folks that are not willing to pay for elite services done with well paid employees driving shiny new trucks.
If you consider that you are providing an elite service, then you will be spending a lot of emotional capital dwelling on the bids that you don't get or the customers you cannot keep.
