Getting Started with Tier

This guide covers getting started with Tier so that you can quickly monetize your SaaS product without regretting it later.

For a deeper dive into the concepts Tier uses, see Tier Basic Concepts.

Setting Up Tier

The best way to interact with Tier is by using an SDK. But if you are using a language that is not fully supported, don't worry! We are eager to add more, and the API surface is small. Get in touch, and we'll do whatever it takes to get you supported.


Get the Node.js SDK by running:

npm install

This will give you a tier command line client, and the library that you can use in your application.


Get the Go SDK by running:

go get

Add the following to your imports list:

import (

Sign Up for Tier

Create an account at using your GitHub or Google account.

Tier will automatically create team accounts for your authorized GitHub or Google organizations, as well as a "solo org" for your individual account.

Create a Token for API Access

You can mint a token to save in the TIER_KEY environment variable.

Tokens are associated with the organization or solo account that creates them.

Define a Pricing Model

The Pricing Model defines the single source of truth that allows everything else in your pricing ecosystem to be nimble while preserving safety.

Create your model by writing a pricing.json file, and running:

tier push pricing.json

You can start by modeling your actual application's pricing model, of course, or you can use this very simple example:

  "plans": {
    "plan:welcome@0": {
      "features": {
        "feature:test": {
          "tiers": [{}]

The pricing model can contain as many versions of as many plans as you like. Whenever you want to make changes to a plan, just create a file with the new version of the plan, and run tier push again.

(Visual plan builder UI coming soon!)

Integrate with Tier

There are two pieces here. The first is telling Tier whenever an account org should be assigned to a plan, and the second is telling Tier about usage.

Assigning Orgs to Plans

Whenever a user signs up for your app, add them to a Plan, which appends to their schedule.

import {TierClient} from ''
import type {OrgName, PlanName} from ''
const tier = TierClient.fromEnv()

// Put this logic wherever you currently handle sign-ups
export const onUserSignUp = async (account: User, plan: PlanName) => {
  // this appends a new phase to the org's schedule, with the
  // specified plan name, like `plan:welcome@0`
  await tier.appendPhase(`org:${}`, plan)

Also call this method when an org changes their plan, by upgrading/downgrading, etc.

Handling Usage

When checking whether a user is allowed to consume some feature, use the tierClient.can() method. When the feature is consumed, call to add it to their bill.

if (await tier.can('org:acme', 'feature:foo')) {
  await'org:acme', 'feature:foo')
} else {
  // suggest they buy a bigger plan, maybe?

Get Paid

Go to the Account page to set up your Stripe account, get the client-side code to safely collect payment methods and attach them to your customer accounts, and so on.

Collect Payment Info

Add the tier.js browser client to every page on your site. This loads Stripe asynchronously, which ensures that you benefit from their bot detection magic.

<script src=""></script>

Then, on the server, get a StripeOptions object with the Tier SDK:

const stripeOptions = await tier.stripeOptions(`org:${org_id}`);

And pass that to the front-end to load the payment entry form:

<form id="payment-form">
  <div id="payment-element"></div>
  <button type="submit">Submit</button>
  <div id="payment-error"></div>

  // use the Tier browser client to do the browser bits
  Tier.paymentForm(<%- JSON.stringify(stripeOptions) %>, {
    form: '#payment-form',
    payment: '#payment-element',
    error: '#payment-error',

Attaching Payment Method to Customer

When Stripe redirects them back to your site, finish the process by calling tier.stripeSetup(org, setup_intent).

if (request.searchParams.has("setup_intent")) {
  await tier.stripeSetup(`org:${org}`, searchParams.get("setup_intent"));

If this raises an error, you can show that to the user, or redirect them to the er.redirect_to_url.url if it's set. (Usually this means that the user has to authorize something, their card was denied, or some other problem.)

Beyond Quickstart Guides: Iterating on Pricing Plans

If you ever want to add a new plan, just edit the pricing.json file to add a new version of a plan, and push it live.

Anyone on the old plans will keep on with their existing plan unless you explicitly call tier.appendPhase() at some point to upgrade them to the new version. All the instrumentation in your code can stay untouched.

Safe, zero-refactoring pricing iteration.
