Billsby vs UniBee

Billsby manages subscriptions, recurring billing, invoicing, and customer lifecycle tasks. It groups subscriptions into products, plans, and cycles that define what is offered, its pricing, and billing frequency. Pricing options include flat fee, per unit, volume, tiered, and ranged models. Usage billing supports metered allowances, real-time API updates, and manual adjustments. Checkout and account-management modals can be added to a website with as little as two lines of code. Failed or declined payments enter dunning flows intended to address payment issues and recover customers. Billsby works with payment gateways but is not itself a gateway. Core costs $45 a month, plus 0.4% on revenue exceeding $15,000/mo; Pro costs $135 a month, plus 0.5% on revenue exceeding $30,000/mo. Billsby says it supports usage-based billing, tax automation, multi-currency billing, and a customer billing portal. It is available via API and web, and is headquartered in London, United Kingdom.
