FreshBooks :: Cloud based accounting and invoicing
Freshbooks is the #1 cloud-based accounting invoicing software designed exclusively for service-based small business owners, with more than 10 million users worldwide. I have been using Freshbooks for about 7 years to create and send invoices to my clients.
Clients can pay me by check or click a link in the invoice to pay by credit card if I allow that option. I can see if and when my clients open my invoice emails and when they pay. I can track my time via a convenient app on my computer which sends that time to my Freshbooks account allowing me to easily create an invoice for all time logged since the last invoice. Freshbooks staff answer the phone right away with support if you need it. Great service!
