Zeller

Zeller is an Australian fintech offering a business transaction account and EFTPOS terminal designed as a modern alternative to the big four banks. Founded in Melbourne in 2020 by former Square and NAB executives, Zeller has grown rapidly by combining fee-free business banking with competitive card payment processing.

The Zeller Terminal ($199 one-off or $0 on a rental plan) accepts tap-and-go, chip, and mobile wallet payments at a flat 1.4% rate for domestic cards. Settlements land in your Zeller Transaction Account the next business day — or instantly if you pay for the Instant Settlements add-on. The transaction account itself has no monthly fees, includes a Mastercard debit card, and offers basic cash flow management tools.

Strengths: The flat 1.4% domestic rate is competitive with Square and undercuts most traditional bank merchant facilities. The terminal hardware is modern and reliable. Having payments and banking in one place simplifies cash flow management. No lock-in contracts — you can cancel anytime.

Limitations: Zeller is a payments and banking platform, not a business management tool. There's no invoicing, quoting, or job management — you'll need separate software for those. The transaction account is functional but basic compared to a full business bank account. International card fees (2.2%) are higher, and the EFTPOS-only focus means no online payment gateway for invoice payments (you'll still need Stripe or similar for that).

A strong option for tradies who want a simple, modern tap-and-go terminal without the complexity of a traditional bank merchant facility.
