In their own words
Kill Bill
Kill Bill is an open-source, programmable billing platform with APIs for pricing models, subscriptions, invoices, and payment gateway integrations. It supports usage-based billing, and plugins connect its payment platform to gateways, issuing banks, and fraud tools. The web-based Kaui back-office interface lets teams configure price books and manage subscriptions and payments. Listed integrations include Stripe, Adyen, PayPal, Braintree, GoCardless, Coinbase, Avalara, and Vertex. Installation options include Docker and Tomcat; Kill Bill can run on Windows, Mac, or Linux computers, or on a Linux cloud server. Described security controls include encryption at rest and in transit, TLS communications, AES-256 stored-data encryption, audit logs, role-based access, and multi-tenant isolation. The self-hosted open-source option includes community support, but customers operate and upgrade it; paid support tiers are purchased separately for customer-managed deployments. The AWS Marketplace option is listed at ~$40/mo, plus AWS infrastructure costs. Hosted-platform pricing follows a separate commercial model. The maker describes the product as serving online businesses, customization-focused teams, startups, and growth-stage companies.
Paystack
Paystack helps businesses in Africa accept online and in-person payments from customers around the world. Listed channels include cards, bank accounts and transfers, USSD, POS, Apple Pay, Google Pay, Visa QR, and mobile money. Its APIs support one-time and recurring payments through an app or website, instant transfers, and customer identity verification. The dashboard provides reporting, alerts, exports, transaction reports, customer search, and purchase insights. Listed integrations include WooCommerce, Shopify, Chargebee, Zapier, Wix, and Xero; developer materials include an API and SDKs for Android, iOS, and Flutter. Paystack says its automated and manual fraud systems help protect against fraudulent transactions and related chargeback claims. It states that it is PCI DSS Level 1, ISO 27001:2022, and ISO 27701 certified. The pricing page lists no subscription, integration, or maintenance fee, but transaction fees apply. In Nigeria, local transactions cost 1.5% plus NGN 100; that NGN 100 is waived under NGN 2,500, with local fees capped at NGN 2,000. Automatic settlement is free and generally reaches the merchant's bank account the next working day.
