Johnson Level & Tool, the level and laser level leader, launched "Jobsite", an Apple application designed specifically for contractors to manage their projects from estimate to invoice, which saves them valuable time.

Start with Jobsite's functions to create an estimate or a quote for any job. Get your clients signature on the app, e-mail them a PDF copy and do the work. Then, turn the quote into an invoice and e-mail it to your customer in seconds. There are 15 different apps in Jobsite, including: Estimate, Quote, Invoice, Daily Diary, Change Order, Meeting Minutes, Request for Information, Bid Request, Extension of Time, Backcharge Notice, Site Instruction, Toolbox Talk, Custom Document, Purchase Order and Subcontract Agreement.

"Johnson Level is continually thinking about how to make our contractor customers' jobs easier and more profitable. The Jobsite app is one-of-a-kind in the marketplace and can be effectively used by both a one person business and a larger operation," said John Dwyer, vice president of sales and marketing at Johnson Level.

Downloading Jobsite to an iPhone, iPad or iPod from Apple iTunes is free and all the apps within it are free to demo and learn about, but for full functionality you can purchase them one at a time or as a group. Jobsite's "Bid Request" comes entirely free.
