WP-Invoice – Web Invoice and Billing


WP-Invoice 4.0 is the most popular and flexible plugin for WordPress that allows you to make your site accept payments. Complete e-commerce solutions out of the box. Flexible and extendable.

WP-Invoice lets WordPress blog owners send itemized invoices to their clients. Ideal for web developers, SEO consultants, general contractors, or anyone with a WordPress blog and clients to bill. The plugin ties into WP’s user management database to keep track of your clients and their information.

Once an invoice is created from the WP admin section, an email with a brief description and a unique link is sent to client. Clients follow the link to your blog’s special invoice page, view their invoice, and pay their bill using one of the available payment system. The control panel is very user-friendly and intuitive.

Credit card payments may be accepted via Authorize.net, PayPal, Interkassa (Eastern Europe), Stripe and 2Checkout. Subscriptions (Recurring Billing) implemented using Authorize.net ARB, PayPal Subscriptions, Stripe Subscriptions and 2Checkout Recurring Billing. More gateways available as Add-ons.

WP-Invoice FAQ


Very nice

I`m testing other invoices plugins, but for now this is the best.

Worst Plugin Support ive had

Good Plugin, does what I need. However, had a few problems which I have asked questions around in support. The questions initially say that they are waiting for moderator approval... Most of my Questions then got deleted and didnt make it past moderator support. the one that did, did not get answered. Each of my questions, I took to Stackoverflow and got answers there relatively promptly.

Extremly poor support

Update Oct., 7 2018 Couldn't find any support form on homepage, so I used the request form for a paid service and I have got no induvidually answer on what I was asking. Although I paid for plugin Invoice PDF, didn't get any solution of the issues I had. For the past I did some German translations for this company, they treated me with nothing. I can't recommand this enterprise anymore and deleted all plugins I used on my site. --- Several times tried to contact the plugin support by their homepage and here. Did not get any solution for my issue I reported. But it's interesting that they offer a paid service by $70/h

I like it a lot

I like this product a lot. I have been using it for over a year now. I use it with the Single Page Checkout ($75), and the PDF plugins ($50). I think the program is near useless without these. Customers need a way to download and save invoices (thus the PDF plugin) and single page checkout allows you to do online commerce. The basic only allows you to send out the bill. So those cost money but it is a one time $125 charge and I like that. What I also like is that I can set it up to be HIPAA compliant and still use PayPal. I have designed the process to send just amounts to paypal while leaving out the specific order information. Clients can see the order in PayPal but are directed to my website to see the actual invoice for services performed. I like this. So if your are ok with some simple PHP it is easy to customize WP-Invoice to your needs. Usability Dynamics has also been somewhat helpful with questions I have had on the development side. What I do not like: I wish the documentation was more complete. I have had to dig to get clarification on parameters and how to use them. They tell us what the parameters are but provide minimal documentation on how they are used, and in most cases no examples. So from a developers perspective, I have had to dig through the code to try to figure out what in the world this or that parameter is supposed to do. I have emailed them with questions, 80% of the time I get an ok response. 20% of the time they ask if I want to purchase development time from them. So, that is frustrating. Please document better. What is also frustrating, there is no bulk send feature for invoice reminders and notices. Once a week I have to open every open account and tell each one to set up a notice and then send them all individually. That is time consuming. I would like a bulk send reminder option for all open invoices such as is available in PayPal. I miss that a lot. So, overall I give 4 stars. It would be 5 for me if the documentation was more complete and if there was a better system for notifications/reminders.
