Good, Needs Options

This is a great plugin for small biz &/or solo workers. Toss in the option to customize and randomize the invoice numbers and add an email template for paid invoices and it’s like 5 stars!

The beauty of Simplicity

Stumbled across this plugin in my search for an invoicing plugin, it does both invoicing and price estimation, simple but elegantly implemented! Loved the final look of the estimate and invoice generated. Clean, clear and precise to the point, yet artistically pleasing to the eye.

Much appreciation to the developer!
Thanks you!!
