Overview

Modern Invoicing for Independent Businesses

Crater is a self-hosted invoicing and expense management platform designed for freelancers, small businesses, and agencies who need professional billing without recurring SaaS fees. The platform combines a Laravel and Vue.js web application with native React Native mobile apps for iOS and Android.

Core Capabilities

Create and send professional invoices and estimates with customizable templates and branding. Track expenses and payments in real time, manage multiple companies from a single installation, and accept online payments through Stripe integration. The customer portal gives clients self-service access to invoices and payment history. Recurring invoices automate subscription billing, while custom fields adapt documents to industry-specific needs.

Deployment and Extensibility

Crater ships with an installation wizard and is available as a Docker image for streamlined deployment. White-labeling features allow complete theme customization across invoices, emails, and the customer portal. The roadmap includes modules API, inventory management, time tracking, and payroll features. Licensed under AGPL-3.0, Crater offers full control over your billing infrastructure without vendor lock-in.
