Best Invoice Plugins for WordPress

November 15, 2019 by Marko Domljanović

Invoices are an indispensable part of every business, regardless of whether that business is online or not. Simply, when a client makes a purchase, an invoice has to be delivered to them, which means that as a business grows, the need for a system that creates and delivers invoices grows too. At some point, managing that process on your own will simply require too much time and effort, and your business will not be able to grow anymore. Not to mention the fact that doing things like this manually can leave a somewhat underwhelming impression on your clients. Fortunately, there are loads of invoice plugins for WordPress websites out there.

But because there are so many of them, it can sometimes be challenging to make the right choice, especially if you’re not that informed on the matter. However, some products do stand out from the rest of the pack, and we are going to discuss and present them in the rest of the article, in no particular order. Let’s go!

Flexible Invoices

A big advantage of using Flexible Invoices as your WordPress plugin for this kind of thing is the array of features it has. Many of them are usually charged for by other companies, so what you get if you download this product will be a great deal indeed. Apart from managing invoices, you can do the same with currencies, and the plugin pays extra attention to taxes because it is in full accordance with the EU’s VAT laws. It should be noted that PDF is the preferred format here, and you will be able to issue and save invoices like that. Additionally, there is also the option to get a summary of all invoices from a particular period if you ever find yourself needing something like that.

There are two tiers of this plugin that require you to make a payment, but at 79$ and 99$ per year, respectively, the price is really not very high. And when you realize that this plugin is used by almost 70,000 websites all over the world, you will be even more sure of the quality it provides.

Sliced Invoices

You will find Sliced Invoices on just about any list of best invoice plugins for WordPress blogs, and the reasons for that are quite numerous. Not only is this plugin used by thousands of different websites, but it also has a lot of built-in templates, which means the time you spend on choosing the design of your invoice will be minimal. That being said, if you want to customize your invoices and give them a personal touch, you can easily do that, too.

You’ll be happy to know that the plugin supports multiple languages, so with it, you will be able to deliver invoices to people from many countries all over the world. It also provides a report-based system through which you can monitor and manage everything.

As for the pricing, the basic form of Sliced Invoices is free, but you can buy various extensions for it, such as the ones for PDF formats, deposits, etc. These extensions can be purchased separately or as a package, with the latter option providing you with a better price.


While WPForms is not exclusively oriented on invoices, it can certainly be of great help in that aspect of your business, too. Because it is very easy to use, nobody should have any trouble with it, plus it will notify both you and your clients when the payment is completed. Obviously, you can automatize the process of sending invoices, but the plugin is also to collect payments through Stripe and PayPal.

On top of being just a nice solid option, WPForm can also help you with a variety of other types of forms (contact forms, surveys, and other things like that), so it is quite possible that you will be saving money in the long run with it. Yes, this is not free: the pricing model WPForm uses is that of an annual subscription, with four tiers – from 79$ to 599$ per year – to choose from. Discounts are often available, though, and when you see the number of features, this thing has you’ll see that it offers some really great value.


Although it may be lagging behind some other entries on this list in terms of the features it has to offer, WP-Invoice is a plugin worth mentioning for two simple reasons: it is quite solid, and it is completely free. This makes it an excellent choice for small and/or new businesses that are looking to avoid any unnecessary expenses. With several thousand users, it can indeed be said that WP-Invoice has gathered quite a substantial following. The options you get here include unlimited and customizable invoices, partial payments, and handy reports. Still, the main advantage of this plugin is that it supports a wide array of payment options, from PayPal to USAePay.

As mentioned, this is an entirely free plugin, but you can even expand the number of features you have at your disposal by downloading various add-ons, which are also free of any charges. Because of all of this, newcomers to the world of online commerce may find this product very appealing.


First of all, Invoicing is easily confused with the previous entry on this list, so keep in mind that these are two separate products. This also fairly simple to use a piece of software, with a quick and easy installation process. A neat feature you can get here is automated tax management, which can save a lot of time. The number of payment options supported is also quite impressive, so your clients will have quite a large selection (PayPal is pretty much a given, but Sage Pay, Square, and many others are also here). Recurring invoices are also available and are a part of the basic, free package.

Yes, you can download WP Invoicing for free, and it really provides a lot of value that way, but keep in mind that there are many add-ons that can be purchased to improve the plugin. You can buy individual add-ons if you see something you particularly like, but you can also buy a membership, which comes in three tiers: 4 months (49$), 6 months (59$) and 12 months (99$). Every membership tier gives you access to all add-ons, new products, and everything else related to this plugin, so investing in a year-long subscription plan may be well worth it.

LittleBot Invoices

While LittleBot Invoices is still relatively new, it is worth pointing it out because of some unique decisions that were made in its creation process. By this, we primarily mean that this app is able to stand on its own, without any other integrations and plugins. Plug’n’play, that’s the way this plugin rolls.

As for the features, you will be able to manage existing clients and add new ones easily, and in addition to invoices, you can also provide estimates. And the whole thing is effortless to use because it was made specifically with WordPress in mind. You will feel right at home!

The plugin is free in its basic form, which is great, although you have the option of purchasing the Stripe Payment Gateway extension if you want to be able to accept credit cards from your clients (the price is 25.99$ per year). Should you really like how this plugin performs, you can always go and support its creator Justin via a donation to help him keep up the good work and develop his product even more. You can even suggest to him which feature to add next!

How can you convert a PDF to a Word file?

Invoices might often be required to be both in PDF or Word format. However, you can convert a PDF format invoice into a Word file. PDF to word conversion might seem challenging, but it brings you the highest quality for converting your PDF files. With a simple drag and drop, you can convert PDF to word files in seconds. Furthermore, there isn’t any file size limit, and even on many platforms, there’s no need to register.

Furthermore, you can convert your PDF to a word file online by uploading your file to an online PDF converter. After, the OCR will activate if you upload a scanned document, and you’ll need to wait for the converter to finish up and allow you to download your Word file.


The invoice plugins mentioned here are just a small number of the options available to you online, but they really do represent some of the best examples of this type of plugins you can currently find. And while most invoice plugins will always offer a free version (or at least a free trial), investing in upgrading a basic model can prove to be a great investment in the long run. This is because most of these (usually annual) subscription models come packed with various add-ons and advanced features that really help your business grow. Having all of that for less than 100$ per year seems like a great deal.

Invoice plugins are something every online business will eventually need because sooner or later, you won’t be able to send invoices on your own. So, if you’re only just setting up shop, start looking for the one that will suit you perfectly immediately. You can start with a free version, of course, but it would be great to install it as soon as possible so that your knowledge of the plugin grows as your business grows. Besides, delivering a uniform invoice with perhaps your logo on it will make you seem much more severe and professional and leave a better impression on your client.
