Zeller: The Quiet All-in-One Banking Tool More Startups Should Be Using

 This information is general in nature and doesn't take into account your personal financial situation or needs. Consider seeking independent financial advice before making a decision. 

If you're starting a business in Australia, chances are you've already looked at the big four for a business transaction account, and walked away annoyed — monthly account fees, card fees, slow EFTPOS setup, and a savings account that pays next to nothing.

Zeller solves most of that in one product, and most small business owners still haven't heard of it.

What Zeller Actually Is

Zeller is an Australian fintech that bundles together the things a new business needs on day one: a business transaction account, debit cards, card payment acceptance (EFTPOS and online), invoicing, and a high-interest savings account — all under one login, with no monthly account fees.

Your funds sit with a licensed, APRA-regulated Australian bank, so it's not some offshore neobank gamble. Over 100,000 Australian businesses are already using it.

The Transaction Account (Your Day-to-Day Bank Account)

This is a free business transaction account with no minimum balance and no monthly fees. You get:

• A BSB and account number for incoming payments
• PayID, bank transfers, and BPAY for paying suppliers and getting paid
• Real-time balance and transaction visibility via the app or dashboard
• Xero integration, so your bookkeeping doesn't become a separate project

For a brand-new business, this alone replaces the "go open a business account at the bank and wait two weeks" step.

Free Debit Cards (Unlimited, Physical and Virtual)

This is where Zeller quietly wins. You get unlimited free physical and virtual Mastercard debit cards linked to your transaction account, with no annual or recurring card fees.

Practically, that means:

• A card for fuel, one for software subscriptions, one for the team credit card holder — without the usual "corporate card program" overhead
• Instant virtual cards for online purchases, so you're not waiting on plastic to arrive
• Built-in expense visibility, because every card's spend is tied back to the same dashboard — no separate expense management software needed

For a 2–10 person operation, this is most of what you'd pay for with a dedicated spend management tool, included for free.

Taking Card Payments (EFTPOS, Online, Invoicing)

If your business needs to take card payments — in person, over the phone, or online — Zeller's terminal and payment links are pay-as-you-go with no monthly rental and no lock-in contract. You can also send branded invoices with a "pay now" link, so you get paid by card or bank transfer without chasing people.

For a startup that doesn't yet have predictable transaction volume, not being locked into a terminal lease or a minimum monthly fee is a real advantage over the traditional merchant facility model.

The Savings Account (The Genuinely Surprising Bit)

Here's the part that gets overlooked: Zeller's Business Savings Account pays a standard variable rate around 2.5% p.a. on your balance — multiple times what the big four banks pay on business savings, which typically sit between 0% and roughly 1% p.a. Zeller has also run promotional bonus rates of up to 4% p.a. on new funds during certain periods, on top of the standard rate.

Interest accrues daily and is paid monthly, and there's no lock-in — money moves between your transaction account and savings account instantly. So instead of letting GST, tax provisions, or working capital sit idle in a 0.1% account, you can park it somewhere it's actually earning something, while keeping it fully liquid.

(One catch: you can't link a debit card directly to the savings account — it's purely for parking funds, which is honestly how a savings account should work anyway.)

Who This Is Actually For

If you're running a small startup or sole-trader-to-small-team business and you need:

• A proper business bank account without the big-bank fee structure
• Debit cards for the team without setting up a separate expense platform
• A way to take card payments without a merchant terminal contract
• Somewhere better than 0.1% to park cash reserves

…Zeller covers all four with one sign-up, no monthly fees, and a setup that takes a day rather than weeks.

The Bottom Line

Zeller isn't trying to be a full bank replacement for an established business with lending needs, FX, or complex multi-entity structures — for that, you'll still want a relationship with a traditional bank or broker. But for a startup or small operator that just needs a functional account, cards, payment acceptance, and somewhere to earn interest on idle cash — it's hard to find a faster or cheaper way to get all of that running.
