I'm going to be as un-biased as I can here. We have heard of a lot of companies increase sales by using software like Jobber in combination with a tablet.
Starting right from the beginning, many people simply load pictures of their work on to the tablet to give the client some inspiration and confidence in the job quality. Using a program like Jobber, you can build quotes on the fly walking around the property with the customer while getting their feedback.
Having the ability to create estimates and email them to the client right in front of their eyes has a certain 'sexy' factor. It just shows that you have a progressive company that can work with the customer to make sure they are 100% satisfied. It also does not hurt to be able to turn that quote into a job with Jobber and then automatically invoice it when completed.
It makes sense when you think about it. People want to know that they will be heard and have immediate response if they are paying the bills. Demonstrating your professionalism and responsiveness with the first impression will help you win more bids.
