OneBill

OneBill is a subscription billing and revenue management platform built for businesses whose pricing is too complex for standard invoicing tools — telecommunications providers, communications platform vendors, managed service providers, SaaS companies and utilities. These organisations rarely charge a flat monthly fee. They combine recurring subscriptions with usage-based charges, tiered and volume pricing, one-off setup fees, hardware, professional services, prorated mid-cycle changes, promotional discounts and contractual commitments, often across multiple currencies and tax jurisdictions. OneBill handles that complexity natively: rating engines process usage records at scale, pricing rules apply the correct rate per customer contract, and the resulting charges consolidate onto a single accurate invoice rather than requiring manual assembly each cycle.

The platform's second pillar is provisioning, which is what the tagline highlights. Billing and service activation are linked, so when a customer signs up or changes a plan, the corresponding service is provisioned or modified automatically through integrations with the underlying network, platform or infrastructure. That removes the gap between a sale being closed and a service going live — historically a manual handoff that delays revenue and frustrates new customers — and it ensures that what is provisioned and what is billed remain in agreement, closing a common source of revenue leakage. Around these core functions sit quote-to-cash workflows including CPQ, order management, contract and amendment handling, dunning and collections, payment gateway integration, partner and reseller channel billing with revenue sharing, tax calculation, and revenue recognition reporting aligned to accounting standards. Self-service portals let customers view usage, manage subscriptions and settle invoices without contacting support. APIs allow the billing engine to be embedded in an existing stack rather than dictating it. OneBill is an enterprise purchase, priced from around USD 1,500 per month, with no free version and no free trial — evaluation runs through demonstration and scoping rather than self-service signup.
