Company profile

researched Aug 2026

Fusebill, now branded Stax Bill, is a cloud-based subscription billing and management platform for recurring-revenue businesses. The software automates recurring invoicing, subscription lifecycle management, payment collection and dunning, revenue recognition and financial reporting, with the aim of replacing manual accounting and billing workflows. Its commerce engine supports a range of billing models including recurring, tiered, consumption/usage-based, storage, user-license and one-time charges.

Feature areas described by the company include subscription management (dynamic pricing, custom registration pages, account hierarchies, custom tracking), recurring billing with automated lifecycle communications and custom invoices, payment collection with automated dunning, accounts-receivable aging reports and payment retries, revenue recognition options including an advanced milestone module for ASC 606 compliance with more than 50 reports, surcharging to pass credit card processing fees to customers where eligible, account hierarchies enabling shared parental payment methods and unified invoicing, and country- and state-level tax calculation with advanced computation via integrations. The platform is built on a double-entry general ledger foundation, which the company positions as the basis for accounting fidelity and compliance-ready financial reporting.

Under the Fusebill brand, the product was sold in three editions with the same feature set: Startup (aimed at companies with up to $1M annual revenue, $295–$894 per month), Rapid Growth (companies with $1M–$10M annual revenue, $895–$3,200 per month), and a custom-quoted Enterprise plan. Payment management covered credit cards, ACH/EFT and PayPal across multiple gateways, and the company reported PCI Level 1 certification and 99.95% system uptime.

Founding story

Co-founders Tyler Eyamie (CEO) and Greg Burwell (CTO) encountered the limitations and manual workload of an outdated billing system while working at Ottawa technology company Protus. After Protus was acquired in 2010 and their roles were made redundant, the two set out to build a better approach to subscription billing, founding Fusebill in Ottawa, Canada in 2011.

Business model

Software-as-a-service subscription billing platform sold to businesses on recurring monthly plans, with tiered editions priced according to customer annual revenue and a custom-quoted enterprise tier. The company also offered its own branded payments offering, Fusebill Payments, and following the Fattmerchant transaction the product sits within the Stax Payments platform of payment acceptance tools.

Recurring monthly subscription fees for the billing platform (flat pricing tiers with no overage charges under the Fusebill branding), plus an in-house payments offering.

Traction

The company reported serving hundreds of companies worldwide. In a company profile, Fusebill cited 110% year-over-year growth in annual recurring revenue, a customer count increase of more than 155%, employee headcount growth of over 40% with expectations of more than 50% additional growth the following year, and roughly 20% month-over-month growth in monthly recurring revenue within its target customer cohort over nearly three years. Marketing materials cite outcomes of up to 80% less time spent on monthly billing, up to a 700% reduction in late or failed payments, and retrieval of 2%–4% of monthly earnings through automated collection tools.

Latest developments

Following the March 2021 acquisition by Fattmerchant, the company rebranded from Fusebill to Stax Bill and now markets itself as part of the Stax Payments platform, which spans in-person hardware, online checkout, embedded payments and mobile readers.
