Kill Bill itself doesn’t provide a UI to manage your accounts and subscriptions. All interactions with the core platform is expected to be done via the REST API and/or the Java APIs (if you decide to embed Kill Bill).
We do provide however Kaui (the Kill Bill Administrative UI): it is a self contained web application, interacting with Kill Bill over HTTP. Its primary purpose is for your support team to handle refunds, credits, cancellations, and adjustments. Additionally, it is also often used by the finance teams to record chargebacks.
Under the covers, Kaui is a series of Rails mountable engines. You can extend its functionality by mounting your own engine(s) (such as to provide a custom UI for your plugin(s)).
Kaui has been designed to be fully multi-tenant, which means you can deploy one UI to access all of your tenants. This blog post explains in a bit more details on how that works.
Along with the multi-tenancy support, Kaui also leverages the authentication and authorization layer built into Kill Bill to restrict users from accessing some screens and actions depending on their permissions (such as refunding a payment, crediting an account, …).
Additionally, Kaui is integrated with most of Kill Bill APIs and provide the following functionality:
Show contact info
Show account balance, available credits, overdue status
Manage existing payment methods
Subscriptions (per account)
List existing subscriptions
Allow to create new subscriptions, change plans and cancel subscriptions
Invoices (per account)
List all invoices
Show invoice details (all items)
Provide link to payments
Allow invoice operations (e.g invoice item adjustment)
Payments (per account)
List all payments
Allow payment operations (e.g refund)
Account Timeline: visualize all the events through time associated with the account and allow specific filtering (subscription, event type, …)
List all the accounts, bundles, invoices, payments, and allow to search based on various fields (account name, external key, email, …)
Tenant configuration (catalog, overdue, internationalization, …)
Create new tenant
Add allowed users
In addition to this doc, we have also created some youtube tutorials.
We provide extensions for some of the official plugins:
When you deploy the self contained war, these mountable engines are mounted by default.
In this section we want to show a few screenshots to give a sense of what Kaui provides (and looks like). The data that we show is synthetic data that we generated using tests. It is certainly not an extensive list of all the screens, but instead we are providing an overview of the main screens.
User and Tenant Setup
In this section, we will show a few screenshots on how to add KAUI users (by user, we mean user of the apis and not customer accounts) and add tenants that these users can manage. Let’s review a bit where the different pieces belong and what needs to be configured in KAUI versus the server side (Kill Bill + whatever shiro backend is used to manage users, roles and permissions):
The management of the users that can access the api along with their roles and associated permissions is managed by Kill Bill server through the shiro layer. Such users must be configured on the server side in order to be available from KAUI and the assumption here is that those already exists on the server side. Please refer to our user management guide.
KAUI contains a default
admin user (and by default Kill Bill also contains such an
admin user with its associated password
password, which has the
root role containing all permissions). This allows to login to KAUI and bootstrap the KAUI configuration (without having to run manual SQL by hand for instance).
The first stage is to login using the default
When login-in, KAUI will check whether some tenants have been configured for this user:
If no tenant current exist for this user, you will be prompted to add a new tenant (next section)
If only one tenant exists for this user, KAUI will automatically select that tenant as the default tenant
If only more than one tenant exists for this user, KAUI will prompt for a tenant to chose (note that cross tenant operations such as adding new users or tenants can still happen as long as the user has the priviledges to do so).
Upon login success one will see the following screen:
Assuming now, we have another user
demo already configured on the server side, and we want to make it available in KAUI. The previous screenshot shows the menu
USERS that allows to add new users known to KAUI. By clicking on that link, one will see the existing users known to KAUI and by clicking on the
+ button, will have the option to add a new user. Let’s make the
demo user known to KAUI:
Upon success, one will see the following screen, and will be able to select the existing tenant(s) that this user can manage:
The creation of tenants can either be done from KAUI directly or through Kill Bill (using api calls). There is a screen that allows to add known tenants to KAUI and from that screen the tenant will either be created in Kill Bill if it does not already exists or simply made visible to KAUI (if it already exists):
Upon success, one will see the following screen (we will come back to that screen later when doing all the per-tenant configuration). Also note that by default KAUI always adds the
admin user as a default user for each tenant.
In order to add users (other than default
admin) that can access this new tenant, one must go back to the user screen and add that newly added tenant (as shown before).
After the user has logged in and after choosing the tenant, the user can search for a specific account (if no search query is entered, a list of all accounts is displayed):
This shows the known information about a given user account:
The billing timeline shows all the events that occurred for a specific user account:
The Analytics screen will only be available when the analytics plugin has been deployed.
It lets you display custom metrics with filtering capabilities. We provide a few by default, but the analytics framework lets you add any desired metric.
Here we show the MRR by plan over time:
The KPM screen will only be available when the KPM plugin has been deployed.
It lets you install and uninstall plugins, as well as start/stop/restart them at runtime:
