Lead Full Stack Developer Used the software for: Less than 1 year ### "Has a learning curve, but really powerful once you get used to it!" 5.0 Overall Rating 5.0 5.0 Ease of Use 4.0 4.0 Features 5.0 5.0 Customer Service 5.0 5.0 Likelihood to Recommend 10/10 February 12, 2018 Very solid and good to work with. Pros The plugin interface is quite extensive. You can write a plugin to do almost anything to satisfy your needs. The support is also very responsive and when an issue is found, they usually fix it very quickly. There are also many guides on their website to get you up and going quickly. Although I haven't tried it yet, you are able to run several Kill Bill instances side by side to ease the load. There is also a web interface which allows you to do most anything. It has a very solid feeling, like nothing can break it. Cons The documentation is lacking with some of the specifics and technicalities. The Java client lacks a vast amount of Javadocs. The web interface lacks documentation and missing confirmation dialogues.

Pros its free it could be usful if it had not taken 3 days to setup just the server before we could even log in Cons its free no support shows there "only volunteers" and if you ask how to do something they suggest they tell you thats not what they do?? CT Chief Technology Officer Chief Technology Officer Used the software for: 3-5 years ### "Powerful Billing + Subscription + Payment System" 4.0 Overall Rating 4.0 4.0 Ease of Use 4.0 4.0 Features 5.0 5.0 Customer Service 5.0 5.0 Likelihood to Recommend 10/10 May 17, 2017 We chose killbill for our start-up after much research. We immediately classified it as active open source project with very clever people behind it. At first we only used a small set KillBills features, specifcally the direct Payment features that integrated with Stripe and PayPal. Now that our business has grown we are currently integrating with the subscription and billing capabilities and are finding it very powerful. The Billing domain often isn't easy.... when we sat down with our product and account managers we encountered so many user stories, edge cases and 'need to haves' it got really scary for us as developers. We were very relieved to learn that KillBill has been built to cater for these sorts of user stories. As we did our analysis we were able to consistently tick off that we had coverage for the use case. We've deployed KillBill in docker to AWS easily. The API documentation thoroughly detailed and includes good user guides. The response time with GitHub issues and Google Groups posts is first class. Overall, I would highly recommend asesssing KillBill when comparing subscription and billing solutions. Pros powerful features open source active and responsive contributors Cons learning curve (but that's because billing is hard) version migrations CE Chief Executive Officer - Co-founder Chief Executive Officer - Co-founder Used the software for: Less than 1 year ### "We found in KillBill a great technological partner, a solid platform with an active community." 5.0 Overall Rating 5.0 5.0 Ease of Use 3.0 3.0 Features 5.0 5.0 Customer Service 5.0 5.0 Likelihood to Recommend 10/10 February 19, 2018 Pros We had been looking for an open source billing platform for some months until we found KillBill. KillBill is very modular. The catalog is a very complete tool, enabling addons, multiple payments and alignment options, and its APIs and push notifications allow us to integrate it very easily with our software. Cons Since KillBill is a very complete and complex tool, sometimes the learning curve can be a little steep. But I've come to realize that most of the things that I had to learn had a reason, and it was that a billing system HAS to be complex. DE Developer Developer Used the software for: 1-3 years ### "We needed a billing system we could easily customize an integrate into our existing platform." 5.0 Overall Rating 5.0 5.0 Ease of Use 3.0 3.0 Features 5.0 5.0 Customer Service 5.0 5.0 Likelihood to Recommend 10/10 June 28, 2018 We have Kill Bill managing invoicing for our customers. We were able to customize it so invoices fit into our existing platform. We have not integrated any payment system yet, but plan to in the future. Pros First and foremost being open source! Dealing with billing is difficult at best, and having access to the source allowed us to more easily understand how Kill Bill worked, how to integrate with it, and how to extend it when we needed something new. The developers have been very helpful via the project's mailing list. The code has plenty of test cases that help with understanding many use cases. In terms of integration with our platform, having a RESTful API to perform all billing actions against has made this easy. In terms of customizing, we have written our own plugin to handle tax items and our own invoice formatter to make sure invoices get rendered how we needed. Both extensions proved easy to achieve. Cons There is a steep learning curve with using the software, but a lot of that is simply a fact of getting any billing system off the ground. The documentation is a good start, but could be expanded to help with that. RE Reviewer Used the software for: Less than 1 year ### "KillBill serves as the core of our in-house billing system" 5.0 Overall Rating 5.0 5.0 Ease of Use 5.0 5.0 Features 5.0 5.0 Customer Service 5.0 5.0 Likelihood to Recommend 10/10 February 18, 2017 We've started using KillBill as the core of our in-house billing system for recurring subscriptions and one-time charges about a year ago. We were looking for a flexible billing solution that would not lock us into any specific vendor, such as Recurly. We decided to try out KillBill and it has proven to serve our use cases well. Here are some points I would like to highlight: - KillBill has an excellent quick-to-respond support team. rep are always very quick to help us with our KillBill related problems and answer our questions. - KillBill is an open source project: I appreciated being able to look at and step through the source code when debugging some of our problems. - KillBill comes with detailed and up-to-date documentation. - KillBill is extensible via a plugin mechanism: we wrote a KillBill plugin to use Authorize.Net as our payment gateway. - KillBill comes with KAUI, a graphical interface that enables non-engineers, such as Sales representatives, to look at billing accounts, invoices, payments and other billing related information. Kaui also supports administrative actions, such as refunding a payment or adding/deleting credit card information. KillBill allows the creation of user roles with a fine-grained permission set, so it is easy to configure different users with different access priviledges. - Just like our other microservices, we run KillBill in a Docker container in a cloud. PR President President Used the software for: 1-3 years ### "Kill Bill enabled us to build a custom, multi-tenant membership sytem with multiple payment gateways" 5.0 December 14, 2017 Pros The system design and feature set allow for easy customization of recurring memberships and payments, handling the complexities and abstracting away the differences as much as possible. It's hard to imagine a custom membership system ever being easy to implement, but Kill Bill makes it feasible and fairly pain-free even if not easy. Their support via the mailing list is amazing for an open-source product. Cons The documentation of some of the more complex API calls is minimal and occasionally requires looking through the code to get an understanding of what parameters to pass in order to successfully make the calls. TL Tech Lead Tech Lead Used the software for: Less than 1 year ### "Skip the pain of building your own subscriptions platform" 5.0 Overall Rating 5.0 5.0 Ease of Use 4.0 4.0 Features 5.0 5.0 Customer Service 5.0 5.0 Likelihood to Recommend 10/10 July 11, 2019 Kill Bill offers a powerful platform we will use to manage the complexity of subscription billing, which will allow us to release features faster with fewer bugs. After building our own tools to manage SaaS subscriptions internally over the past several years, we see the advantage of outsourcing it. Pros open source with an active community, powerful feature set, pluggable architecture, documentation Cons There are still some opportunities that we expect to see fulfilled in the future because work is actively occurring on the platform. You can take a look at open issues tracked in GitHub to get a sense of ongoing work. PM Product Manager Product Manager Used the software for: 1-3 years ### "We are a SaaS company using Kill Bill to manage billing of our 250,000 subscribers" 5.0 Overall Rating 5.0 5.0 Ease of Use 4.0 4.0 Features 4.0 4.0 Customer Service 3.0 3.0 Likelihood to Recommend 10/10 August 3, 2017 Ability to control billing allows far better control over billing fees as well as capability to optimize in any way your business may see fit. Pros Control. Open source and a beautiful pluggable architecture. Building upon the solid base of subscription management provides the ability for unlimited customization for any business. Avoid the problems associated with outsourced billing. Cons A bit more complex setup than using one of the SaaS vendors, which are easier to get started with although not providing the level of control that's optimal for some progressive companies.
