Stax Bill

Stax Bill (formerly Fusebill) is a cloud-based recurring billing and subscription management platform that automates the quote-to-cash process for businesses with subscription or recurring revenue models. It handles the full subscription lifecycle, from sign-up and plan changes to invoicing, payment collection, dunning, and revenue recognition, and syncs the resulting financial data back to accounting and ERP systems. The platform is positioned for SaaS companies, service providers, and other subscription businesses that want to remove manual effort from billing operations.

The product centers on a flexible product and pricing catalog that supports multiple billing models, including fixed recurring fees, tiered pricing, usage-based (metered) billing, one-time charges, and add-ons. Automated proration calculates daily rates when customers upgrade, downgrade, or change plans mid-cycle. Invoicing runs on recurring schedules, while automated dunning, payment retries, and accounts-receivable aging reports work to recover failed payments and reduce involuntary churn. A self-service customer portal lets end users manage their own subscriptions, payment methods, and invoices.

Stax Bill includes an ASC 606-compliant revenue recognition module (with an advanced milestone option for service organizations) and a reporting suite the vendor describes as offering over 50 real-time reports covering MRR, cash flow, and revenue by product, plan, or customer. It integrates natively with Salesforce, HubSpot, NetSuite, and QuickBooks Online, connects to multiple payment gateways for credit-card and ACH processing, and exposes a REST API plus webhooks for custom workflows. Stax Bill was founded in 2011 as Fusebill in Ottawa, Canada, and became part of Stax (formerly Fattmerchant) following a 2021 acquisition.
