Joist is a free tool designed for contractors to help them save time, win more jobs, and stay organized. With Joist, contractors can create quick, professional estimates and invoices, accept payments, and manage projects from anywhere. The app allows contractors to send estimates to clients before leaving the job site, remove the bottleneck of estimating and invoicing, and accept credit card and e-check payments from clients directly through the app. Joist also enables contractors to easily manage clients, create, organize, and store valuable client information, and access their information anytime, on the go.

Joist offers a range of features to help contractors calculate material and labor costs when estimating and invoicing, build a list of commonly used items, customize estimates and invoices with company information and logos, attach client contracts and collect signatures directly on the spot, and preview estimates and invoices before sending. Contractors can also attach photos to their estimates and invoices, print or email them on the spot, create personal messages for clients, convert estimates into invoices, keep track of customer payments and how much they are owed, manage and save client information, set tax rates, and export everything into their accounting program.

Joist is used by all types of general and specialty trade contractors, estimators, and service companies, such as general contractors, handymen, electricians, plumbers, builders, landscapers, roofers, painters, carpenters, heating and air conditioning, flooring, siding, tile, concrete, paving, bathroom and kitchen remodeling, renovators, deck builders, drywallers, pest control, and more. The app is available on Android, iPhone, iPad, and desktop computer, and customer support is available 8AM-10PM EST M-F via email, live chat, and phone.
