The Billflow Plan Picker allows you to easily show your product pricing in your app, let users checkout, see what plan they're on, and change their plan. Because it's connected directly to your Stripe account, you never have to worry about updating your website when you change your pricing.
You have the option to show subscribers the current plan they are on, or automatically show the Customer Portal.
A Service is a collection of Stripe Products & Prices that make up the tiers & intervals of a service offering. If you have not created a service already, you will have the option to create a 'demo' service. To learn how to create your own service and specific pricing model, real along here.
Select the service you wish to create a Plan Picker for.
Following are the options available on the Plan Picker
The Plan Picker will always show plans to unsubscribed users. If a customer is subscribes, you have the option to then show them the Plan Picker with their selected plan, or to show the Customer Portal. If you are looking to have a distinct plan selection page, leave this option off. If you'd like to have an all-in-one page for subscribing and viewing billing information, turn this option on. Commonly used for Freemium models.
Want to hide a certain tier that's only available to a certain group or an a certain time? Use hide tiers to select from your available tiers and users will not see it as an option.
Want to disable certain tiers to run a promotion of things to come? Use disable tiers to select from your available tiers and users will see that tier greyed and unavailable now.
Use this option to charge a plan change immediately instead of prorating the difference on the current billing cycle. This will set the billing cycle anchor date to the date of the plan change.
Turn this option on to show how much the annual plans cost as a monthly rate. Eg: A $120/yr plan would show $10/mo billed annual
Turn this option on to show a discounted flag on the annual plans.
Select a billing interval to be the default.
Only use this option if you want to change the default interval and you have a custom interval like "Every 3 months" or "Every 6 weeks". The value will just be the number in your interval.
Fill this option in with a Stripe Coupon ID or Promo Code to have a coupon automatically applied to any tier chosen. Useful feature for running a promotion on a specific URL.
You must choose how you will identify customers. You have an option to pass in a customer's email address or their Stripe Customer ID in order for Billflow to look up their information in Stripe.
Identifying with email is simpler as it requires less data to store. Identifying with Stripe Customer ID is more robust because you do not need to handle email changes and is also needed when doing a tenant based architecture where multiple account are under the same group.
Turn on to enable security on your page in test mode. This option is required in live mode. In order for the customer portal to securely display customer billing information, a hash must be passed to the billing page options. This hash must be generated on the server with the logged in user's email or Stripe customer ID, whichever you are using to identify users. This step is covered in more detail in the Secure Setup.
If you enabled "Show Customer Portal for Subscribers" you will see Customer Portal Settings. To learn about the options available to it or about embedding a separate Customer Portal page, check out the Customer Portal.
When a user selects a plan before they have subscribed, it will automatically go to the correct Checkout Form for that tier. To learn more about the options available on it or about embedding a separate Checkout Form, check out the Checkout Form.
All Billflow billing pages have the ability to automatically detect the customer's browser language preference and translate the billing page accordingly. If the language is not supported by our page, a default language will be displayed. The default language is English US.
Turn on to automatically detect the customer's browser settings and translate the page. If not enabled, select your default language. Not seeing a language you need there? Contact us on the chat to request a translation.
Turn this option on to pass in your own translations. This can be used to host your own language files, but can also be used to change the text of specific sections to your desired text. To learn more about this option, read along here.
Turn on to enable the handleResponse function. The function is used to handle events with custom code when events happen on the billing page like button clicks and actions performed. To learn more about events available and sample code snippets, read along here.
Turn on to enable debug mode for extra console logging.
Embedding the Plan Picker is a two-step process. For the client side installation just copy and paste the provided HTML snippet. The next step is secure setup.
If you have a frontend framework, check out the samples of embedding with those.
The customer portal must be behind some kind of user authentication in order to safely show customers their billing information. Billflow authenticates users with an HMAC hash generated for the logged-in user, this allow is to work with any authentication system. If you are using a No-code platform, make sure to check out our plugins as they handle this step for you. If you are integrating into a custom application, continue on.
Your code to generate an HMAC for your app must be placed in the back-end of your application. Grab the snippet from the dashboard to add to your server. You may generate the HMAC with their the user's email OR the user's Stripe Customer ID (customer_id).
The HMAC generated will be passed to the client-side snippet to a property called 'hash'.
const crypto = require("crypto");const email_hash = crypto.createHmac("sha256","YOUR_SECRET_KEY" // SECRET KEY (KEEP SAFE!)).update(req.user.email).digest("hex") // PASS THIS TO FRONT-END
email_hash = OpenSSL::HMAC.hexdigest('sha256', # HASH FUNCTION'YOUR_SECRET_KEY', # SECRET KEY (KEEP SAFE!)current_user.email # REPLACE WITH USER'S EMAIL ADDRESS) # PASS THIS TO FRONT-END
import hmacimport hashlibemail_hash = hmac.new('YOUR_SECRET_KEY', # SECRET KEY (KEEP SAFE!)request.user.email, # REPLACE WITH USER'S EMAIL ADDRESSdigestmod=hashlib.sha256 # HASH FUNCTION).hexdigest() # PASS THIS TO FRONT-END
$email_hash = hash_hmac('sha256', // HASH FUNCTION$user->email, // REPLACE WITH USER'S EMAIL ADDRESS'YOUR_SECRET_KEY' // SECRET KEY (KEEP SAFE!)); // PASS THIS TO FRONT-END
Generate an HMAC with SHA256 whenever a user logs into your app. Most web frameworks will have a method or library to help you do this. You'll need your app’s secret key and the email or user_id of the currently logged-in user.
Secret Key Get Your Secret Key
Seeing 403s? You can verify your HMAC is being generated properly by creating one here. Use "SHA256", pass in the customer's email or customer ID, and use your Billflow secret key as the secret. Compare that with what you're generating server-side and what's being passed to the client-side.
You can modify the order that tiers appear from their default ordering by price. Metadata tags are used in Stripe to do this, add these to your Stripe Product.
Add this metadata property to a Stripe Product. The lowest value tier appears left-most on your Pricing page.
Add this metadata property to a Stripe Plan. The lowest value plan appears higher on a tier with multiple pricing plans.
The pricing page has many more powerful features that can be unlocked with some simple coding. Check out the developer docs to learn more.
