Ignition

Ignition, founded in Sydney in 2013 as Practice Ignition, is a revenue and billing automation platform for accounting firms, bookkeepers, and professional-services businesses. It combines digital proposals, engagement letters, automated invoicing, and integrated payments into one system so firms can win clients, get paid on time, and reduce scope creep. More than 7,500 businesses use Ignition, and customers processed roughly $3.1 billion through the platform in 2025.
