While searching for online invoice generator, I have encountered a very simple but highly customizable web application to generate invoices online. It is available at https://create.onlineinvoices.com/invoices-generator/create/2. One of the important facility provided by this tool is that if we want to generate multiple invoices for a single client then we need to enter client details only once in the text box adjacent to the “Bill To”. Then after entering other details after clicking on “Preview/Print” button, the invoice is being displayed in another tab of the browser and all details of the invoice remains available in the first tab of the browser. So after downloading invoice from the second tab of the browser, we can safely close it. The form to generate invoice remains available in the first tab of the browser. Then after making necessary changes we can easily generate next invoice. However if we want then we can easily create account on this website also to mange client information as well as invoices being generated for them.
