Invoicing software for Australian sole traders and small businesses
Create professional invoices and quotes in minutes. Built for Australian sole traders, contractors and freelancers - with GST, ABNs and tax invoice rules handled by the software, not left for you to remember.
Most invoicing tools are either built for a different country and adapted for Australia as an afterthought, or built for accountants and priced accordingly. Apsis is neither: GST, BAS quarters and ABN fields are part of the data model from the start, and the free plan is a real free plan, not a 14-day trial.
A quote you send becomes an invoice with one click once your client accepts it online - no re-typing line items. An expense you log lands in the right GST category automatically, so the GST is already recorded when you need it rather than rebuilt from a shoebox of receipts. On Plus, the quarterly BAS figures are ready to read off.
Common questions
What is the best invoicing software for a sole trader in Australia?
The best fit is invoicing software built for the Australian market specifically - GST calculated automatically, ABN and tax invoice fields built in, and pricing that doesn't assume you have a bookkeeper. Apsis is built around exactly that: quotes, invoices, expenses and GST in one system, with BAS figures on the Plus plan, sized for a one-person or small business rather than a full accounting department.
Is there a free invoicing tool in Australia?
Yes. Apsis has a genuinely free plan - 5 clients and 20 invoices per month, no credit card required to start.
What must an Australian invoice contain?
At minimum: your identity and ABN, the client's details, a unique invoice number, the date, a description of what was supplied, and the GST amount if you're registered - sales over $1,000 need the buyer's identity too. See our full breakdown in “What must legally be on an Australian tax invoice” for the exact ATO requirements.
Can invoicing software also handle quotes and expenses?
It should - otherwise you're re-entering the same client and line-item details in three separate tools. Apsis converts a won quote into an invoice with no retyping, and tracks expenses (with GST split out) in the same system as your invoices, so the GST on every expense is already recorded when BAS time comes.
