Billsby is subscription billing software for recurring revenue. See 2026 pricing plans, key features, integrations, pros, cons, and FAQs.
Billsby is a subscription billing platform headquartered in London, UK, built for businesses running recurring-revenue models. It targets startups through enterprises with tools to manage products, pricing plans, and customer billing without building billing infrastructure from scratch.
The platform emphasizes customization and developer accessibility, offering a documented API alongside its billing dashboard so engineering teams can embed subscription logic directly into their own products.
Billsby handles recurring and usage-based billing, invoice generation, and online payment processing, along with dunning management to recover failed payments and reduce involuntary churn. It supports multi-currency billing and automated tax handling for businesses selling across regions.
Both pricing tiers include unlimited products, plans, and customers rather than capping catalog size, with reporting dashboards for tracking recurring revenue and subscription activity, and an API for developers integrating billing into custom applications.
Billsby uses a hybrid subscription-plus-revenue-share model rather than flat per-seat pricing. The Core plan is $45/month plus 0.4% of monthly revenue above $15,000; the Pro plan is $135/month plus 0.4% of monthly revenue above $50,000, adding priority support and more advanced reporting.
Because the revenue-based fee only applies above a threshold, small subscription businesses pay close to the flat monthly rate, while the effective cost scales up as a company's recurring revenue grows past the threshold.
Billsby's Core plan is $45/month plus 0.4% of monthly revenue above $15,000; the Pro plan is $135/month plus 0.4% of monthly revenue above $50,000.
