Best business app I’ve ever used!!! I tried many others. Nothing compared with how easy it is to send estimates and receive digital signatures from customers. It tells you every time a customer just looks at/opens the estimate and 1 button tap to turn an estimate to an invoice keeping track of every document you create. Wonderful!!!!!
A must for small business and estimating purposes!!!
