What it is

Makes and manages online subscriptions with a customizable billing system.

What you can make with it

Automations like: when a new customer signs up for your SaaS, send them a welcome email and generate their first invoice.

How it helps

Saves time setting up and managing subscriptions, letting you focus on your core business.

Real use case example

"A founder launches a new SaaS and needs to set up subscription plans and automate invoice generation. They use Billabear to create a billing system in 30 minutes, then set up an automation to send welcome emails to new customers and generate their first invoices. The founder now has a professional-looking billing system up and running, saving them time and hassle."

If you're new

Pick this up when you're starting your SaaS and need a simple billing system.

If you're senior

Reach for this when you need quick and customizable subscription management for your existing SaaS.

Common confusion cleared up

Billabear is not a payment gateway, but rather a billing system that integrates with existing payment gateways.
