Sleek vs a traditional accountant vs DIY software

A quick honest comparison so you can see where a fixed-fee accountant fits against the alternatives.
What matters to a seller Sleek DIY spreadsheets Traditional accountant
Upfront cost From A$1,800/yr, all in Low Variable, often quoted per job
Multi-channel reconciliation Automated across platforms Manual, error-prone Sometimes, usually extra
GST and BAS lodgements Tracked and lodged for you Your responsibility Yes
Ongoing support Dedicated accountant, direct line on Pro None By appointment

When you might not need us yet

If you sell on a single channel, sit well under A$75,000 in turnover and enjoy doing your own books. The moment a second channel, GST registration or overseas sales enter the picture, that is when a specialist starts saving you more than it costs.

FAQs on ecommerce accounting in Australia

Do I need to register for GST if I sell online in Australia?

You must register once your turnover reaches A$75,000 over a rolling 12 months, or as soon as you reasonably expect to cross it in the next 12 months, whichever comes first. You then have 21 days to register. GST is charged at 10%, calculated as one-eleventh of the sale price. Below the threshold registration is voluntary. See our guide on how to register for GST.

How often do I have to lodge a BAS?

Most online sellers lodge quarterly, which applies to businesses turning over under A$20 million. At A$20 million or more, BAS becomes monthly. Even a quarter with nothing to report still needs a BAS once you are registered. Here is how to lodge a BAS.

Can you handle sales across Shopify, Amazon and eBay at once?

Yes. We connect each channel to Xero, then reconcile revenue, platform fees and shipping costs per channel. The result is one clear profit figure rather than five disconnected dashboards. Payment processors like Stripe and PayPal feed in the same way.

What tax does a small online business actually pay?

A Pty Ltd selling online pays company tax at 25% as a base rate entity (turnover under A$50 million), plus GST if registered. Sole traders are taxed at personal rates instead. We map your structure to the right obligations. More in do small online businesses pay taxes.

I sell to overseas customers. Does that change my accounting?

It adds multi-currency conversion and foreign platform fees, which need careful reconciliation to report income correctly. Exports are often GST-free, but the rules depend on what and where you sell. We handle the categorisation so cross-border sales stay accurate and compliant.

Can you clean up a year of messy ecommerce books?

Yes, catch-up work is common when sellers come to us mid-year. We reconcile the backlog, sort any outstanding ATO obligations, and set up a routine so your books stay current from then on. Dext captures historic receipts so you do not have to dig through paper.
