How It Works

1. Once you sign up for our Broker Program, we will give you a unique Broker ID. This ID will allow you to send your clients to our website or app, where you will be credited for every purchase!

Thimble also allows you to embed our purchase widget onto your own website, so your customers can purchase on-demand insurance through your site.

2. Customer events like quoting, purchasing, extending, and more will be tracked and credited to your account. You can log in to your Broker Portal anytime to see your customers interaction.

3. That’s it! You will get a commission for each and every policy they purchase with Thimble. Commissions for purchases are paid once a month.

Real-Time Dashboard

The Thimble Broker Portal provides you with referral links to the Thimble App and website. Sending these links to your customers will track when they create an account, purchase, extend, cancel, or modify a policy. ​ 

All of these actions will be displayed in your referrals table in the portal. As a broker, you will be paid a 10% commission for your customers’ purchases. Commissions are paid monthly.

  • How do I get paid my commissions? Commissions will be paid in accordance with your agreement with Appalachian Underwriters. Please reach out to Appalachian Underwriters support if you have any questions about your commissions on Thimble policies, including any agent bonuses.
  • What is the Thimble Broker Program? Our Broker Portal makes it easy for top brokers and agents to partner with us and offer our insurance coverage to clients.

    Through this portal, agents can track clients across time, and attribution is assigned to the agent through a unique link delivered via email or phone. Commissions are processed automatically: we pay a 10% commission on the policy value for anyone referred, across all purchases. And you receive a commission on every policy the client buys from us in the future, not just the first purchase!

    Please note: you must be a licensed property & casualty broker in order for Thimble to process commission payments.
