It’s time to fluff and refresh Kill Bill’s most frequently asked questions (FAQs)! If your question isn’t covered here, make sure to check Part 1 and Part 2.
General Questions About Kill Bill
I’m a software consultant/shop. Can I implement Kill Bill for my customers?
Yes, others have used Kill Bill as white label software. The source code has a permissive Apache Version 2.0 license, and you can hide the Kill Bill brand from the API and user interface. If you need further information, please feel free to contact us.
What is Kaui?
Kaui is a browser-based application that enables back-office staff (in Finance, Marketing, Development, etc.) to perform Kill Bill-related tasks, such as creating customer accounts, subscriptions, adding plugins, and so forth. “Kaui” (KAUI) stands for Kill (Bill) Admin User Interface. For more information, see the Kaui User Guide.
Why should I choose Kill Bill over a SaaS alternative?
Using a SaaS solution (for example, Zuora or Chargebee) seems like a smart business decision. These types of SaaS billing solutions have been around for several years, know their clients’ needs, and often give the impression that they can solve all of your billing problems.
But just as there are benefits to using a SaaS billing solution, there are also disadvantages, and they aren’t minor. The largest disadvantage is if you work with a SaaS billing provider, all of the data associated with your revenue is in their hands – not yours. That precious data can even be difficult to access at times, believe it or not.
Before you lock yourself into a SaaS subscription billing vendor, consider the following:
- Restrictions in integrating with existing business software (accounting, CRM, etc.)
- Limited feature sets
- Limited choices in third-party providers, such as for payment processing, tax calculation, fraud detection, etc.
- Issues with testing (limited number of sandboxes at a high cost)
- Inadequate analysis and reporting solutions (i.e., holding your data hostage)

Do you have customers in [country name] or in [specific industry] that are using Kill Bill? Can you put me in touch with them?
You can certainly contact us to ask, but Kill Bill users we’ve worked with in the past often restrict us from disclosing this information. We recommend you post this type of question on the Kill Bill Community (mailing list), which is quite active.
Can I see a list of companies that use Kill Bill?
This image from our website displays logos of just some of the organizations that use Kill Bill. We know that the number of Kill Bill installations numbers in the thousands.

Questions About Kill Bill’s Features
What is a plugin?
A plugin is software written on top of the Kill Bill platform that interacts with the system. You would use a plugin to implement a specific feature or behavior that’s not part of the core Kill Bill system. See the Plugin Introduction.
Can I use Kill Bill to send email notifications to customers about their account?
Yes, you can use the Email Notification plugin to send emails regarding late payments, failed payments, and other events that affect customers’ accounts.
Does Kill Bill work with multiple currencies?
Yes! To use multiple currencies, you would define each currency in the catalog. You would also define a currency for those customer accounts that don’t use the system’s default currency. For more advanced currency topics, see the Analytics Guide and Payment Control Plugin Guide.
Can I use Kill Bill to communicate with customers in their native language?
Kill Bill supports translations in the catalog, emails, and invoices. To read more about Kill Bill’s international features, including time zones and currencies, see the Internationalization Overview.
What kind of analytics can Kill Bill provide for my accountants and finance teams?
