Tech Lead Computer Software ### "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 10, 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. Review source Non-incentivized review: any software user can leave a review for any product listed on our site.

Developer Design ### "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. Review source Non-incentivized review: any software user can leave a review for any product listed on our site.

Senior Software Engineer Information Technology and Services ### "Very flexible product, but steep learning curve (for non-trivial use cases)" 4.0 Overall Rating 4.0 4.0 Ease of Use 3.0 3.0 Features 4.0 4.0 Customer Service 5.0 5.0 Likelihood to Recommend 8/10 June 4, 2018 A ready-made but still heavily customizable billing platform. Writing our own would have costed a lot without the same results. Pros \* Extremely customizable: out-of-the-box features cover many scenarios, but if you need more you can write your own plugin to change default behaviours. \* Osgi plugins infrastructure make easy install and update custom plugins at runtime. \* Event-driven model allows to develop plugins as black boxes (as it should be...). \* It's FOSS. \* Developers are very dedicated and open to contribution, and Community support is very responsive. Cons \* Learning curve is quite steep, \*if your use cases are not trivial\*. Custom deploy can be challenging, if you have to deal with reverse proxies and back/front separation. Understanding the catalog abstraction and how options affect behaviour requires a domain knowledge not easy to achieve. One needs to dive into source code to understand what's happening or how to use well the API. \* Event-driven model make hard to fully understand what's happening.

MG Majeed G. CEO ### "Comprehensive, robust solution for subscription billing" 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 0/10 May 14, 2018 Pros We needed a long-term solution for billing and payments for our subscription services. We looked everywhere - commercial, open-source, hosted, on-premise etc. Nothing came close to the comprehensive feature-set of KB. Other options with good features were enterprise scale products with big price tags. What made KB even better is the responsiveness of the support team. We get answers to our question usually within one business day. We were able to deploy KB within our data center and integrated using a Java plug-in and API's. The peace of mind that all information is within our data center is great. Having a no-license-fee, open-source Java-based solution that goes well with our tech stack and has the potential to save our team hours of work doing mundane billing & collection activity each month is priceless! Cons The initial learning curve was steeper than we had imagined. However, the documentation was well written and support was great so we were able to overcome it. I also wish there were more pre-built reports in the "analytics plug-in". Review source Non-incentivized review: any software user can leave a review for any product listed on our site.

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??

Matias G. L. Chief Executive Officer - Co-founder Telecommunications ### "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 16, 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.

Chris S. Lead Full Stack Developer ### "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 9, 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. Review source Non-incentivized review: any software user can leave a review for any product listed on our site.

President Computer Software ### "Kill Bill enabled us to build a custom, multi-tenant membership sytem with multiple payment gateways" 5.0 Overall Rating 5.0 5.0 Ease of Use 3.0 3.0 Features 4.0 4.0 Customer Service 5.0 5.0 Likelihood to Recommend 0/10 December 13, 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.

SE ### "Really good tool for billing in cloud technology." 5.0 Overall Rating 5.0 5.0 Ease of Use 5.0 5.0 Features 5.0 5.0 Customer Service 0.0 0.0 Likelihood to Recommend 10/10 September 20, 2017 Pros Really good, if catalog update is available this product is good for use. invoice generation for fixed and recurring billing is so good. Cons customer support online not available. Special character not supported in product name like(space, starts with numbers in product name) . I will ran my application and killbill application in same server, killbill change the server environment(i.e convert to UTC Time-format once configure in any region) so it affect the other application.
