What BillaBear is

BillaBear is a subscription management and billing system that integrates with Stripe and provides a REST API. It covers plans, subscriptions, add-ons, invoices, quotes, hosted checkouts, paylinks, vouchers, credit notes, dunning, and subscription reports. Billing options include fixed prices, usage-based packages, volume and graduated tiers, fixed-plus-unit charges, and per-seat pricing. It supports multiple brands and currencies, plus tax rules for countries and states, configurable thresholds, EU reverse charge, one-stop-shop, and VAT Sense integration. Workflows can retry failed tasks, including API requests, so later steps can continue. Templates for invoices, quotes, PDFs, and email can be managed with Twig or email service provider templates. Integrations listed include Stripe, Slack, Freshbooks, Xero, Mailchimp, EmailOctopus, SendGrid, MailGun, and Postmark; Zendesk and Freshdesk help support agents locate customer profiles. SDKs are listed for PHP, Java, Go, JavaScript, Ruby, and Python. The software is free to use and modify under the Fair Core License, which restricts competing for two years. Managed cloud hosting is currently unavailable.
