Octobat is a billing, invoicing, and tax-compliance platform for online businesses. It automates the creation, delivery, and storage of legally compliant invoices, credit notes, self-billing invoices, and tax receipts for every online transaction, and provides a real-time tax (VAT / GST / sales tax) determination engine for tax-exclusive and tax-inclusive billing models. Octobat integrates with Stripe, GoCardless, and other payment providers, and exposes a Stripe-style REST API at base URL https://apiv2.octobat.com authenticated with HTTP Basic (secret key). Octobat also ships Beanie (a hosted checkout) and Plaza (marketplace / platform tax and invoicing for connected accounts). Operating status - Octobat was acquired by Mirakl in November 2021; the standalone marketing site (octobat.com) now redirects to mirakl.com, while the developer documentation at docs.octobat.com and the apiv2.octobat.com API remain available to existing integrators.
