For any company venturing into online business the ability to send estimates and invoices electronically is an important requirement. As this is such a vital part of your online business and involves sensitive customer information it is important to use a professional and reliable service.
We recommend (and use) Zoho Invoice for this task. We have no affiliation with Zoho and are purely recommending them as a service to our customers who require an online invoicing service. There is a free option for companies who send less than 5 invoices per month, but even the paid options are very reasonably priced. Just click on the image to find out more.
