“Powerful Billing + Subscription + Payment System”

OverallWe 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.
Prospowerful features open source active and responsive contributors
Conslearning curve (but that's because billing is hard) version migrations
Recommendations to other buyersfirst understand deeply your own billing user stories, this is where most of the complexity lies

“Own your data, master your tools”

OverallKill Bill has played a major role in the launch of our SaaS project: it helped manage and master the payment process, while keeping it on our servers and under our management (which would help if we need to change payment providers or want to set up another one)
ProsSelf-hosted, fully working set of features, lots of configuration possibilities
ConsComplexity to understand and implement at first, documentation

“KillBill serves as the core of our in-house billing system”

OverallWe'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.

“Has a learning curve, but really powerful once you get used to it!”

OverallVery solid and good to work with.
ProsThe 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.
ConsThe 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.

“We are a SaaS company using Kill Bill to manage billing of our 250,000 subscribers”

OverallAbility to control billing allows far better control over billing fees as well as capability to optimize in any way your business may see fit.
ProsControl. 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.
ConsA 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.
