Billsby
London, United Kingdom
What it is
Billsby is subscription management software for recurring billing, invoicing, and customer lifecycle tasks. It structures subscriptions as products, plans, and billing cycles, with pricing options that include flat fees, per-unit, volume, tiered, and ranged models. For usage billing, teams can set metered allowances, send real-time usage updates through the API, or make manual adjustments. Website checkout and account management modals can be added with as little as two lines of code. Failed or declined payments can enter dunning flows intended to help resolve payment issues and recover customers. Billsby connects with payment gateways but is not itself a gateway. Its integrations include Zapier connections to more than 5,000 applications, accounting tools, Webex, Billsby Pages, and website builders. A free plan is listed, with no price specified. 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 describes its service as designed for startups seeking flexible recurring billing they can integrate and adapt as they grow.
