Zeller

Zeller is an Australian fintech company that offers an alternative to traditional business banking for small and medium-sized businesses. Its platform combines EFTPOS payments and card machines, online invoicing, business transaction accounts, debit and corporate cards, expense management and real-time financial reporting in a single system. More than 100,000 businesses in Australia use Zeller, which operates there and is expanding into the United Kingdom.

The company's stated aim is to widen access to enterprise-grade financial tools. It argues that large enterprises receive tailored solutions while smaller businesses are underserved, and that consolidating multiple disconnected financial providers removes complexity. It also criticises the opaque pricing and restrictive contracts common among incumbent providers, and positions transparency as a core commitment.

Technical work spans payments technology, a financial software platform, data encryption and security, real-time reporting and expense management systems. Zeller states that customer data is protected with end-to-end encryption and that the platform runs at 99.99999% uptime. The underlying business problem is cash-flow acceleration: getting businesses paid faster through integrated payments and banking services.
