Salesman is great app for sales representatives. With this app you can simply create purchase orders and it can easily replace your handwritten order sheets.
In app you can import your products and clients with images.
While you are creating a purchase order, you can use built-in bar scanner or just manually add products into the list.
Customer can also sign the order.
App can also be used as a your company's product catalogue.

When order is complete, app generates a PDF, XLS and CSV file and you can share it the way you want.
You can also use direct CSV file upload on your server.
