The platform
Every part of the business, structured
No sprawl, no dependency on a dozen disconnected tools. Just the core of running a business, done right - and connected end to end.
Quotes → invoices
Sequentially numbered, PDF-ready documents with a clear status lifecycle - Draft, Sent, Part-paid, Paid. Your client accepts a quote online from the emailed link, then it converts into an invoice in one click.
Expenses & GST
Track vendor costs by category with GST split out and the receipt attached, so every deduction is on record when you or your accountant need it.
Tax, BAS & deductions
Estimate income tax as you go and see each BAS quarter's figures - GST collected, credits, net payable - ready to copy into the ATO portal. Apsis does not lodge.
Tasks & Kanban
Plan operational work per client, then track execution on one global board.
Timesheets
Start a timer or log hours against clients and tasks, then pull the unbilled entries straight into an invoice.
Vehicle logbook
Log trips as you drive and Apsis works out your business-use percentage the way the ATO logbook method expects - odometer readings, a continuous 12-week period, and a record you can hand over.
Deadlines & the $75k line
Every AU tax date that applies to you - BAS quarters, lodgement, super - on your calendar and in a reminder before it bites. Apsis also watches your rolling 12-month turnover and warns you as you approach the $75,000 GST registration threshold. On Plus, it packs the whole year up for your accountant at EOFY.
Recurring & retainers
Put a monthly retainer or a repeating invoice on a schedule once, and it issues itself on the cadence you set.
The money flow
From first quote to money in the bank
Apsis tracks the whole lifecycle with a clear status on every document - so you always know what's owed, what's late, and what's paid.

Late payer? Overdue invoices are flagged automatically and Apsis reminds you about them. OnPlus, it can also email your client a payment reminder before and after the due date.
AI assistance · Plus
AI that already knows your business
Not a chatbot bolted onto the side. Apsis AI writes the documents you send, and answers questions about your own clients, invoices and tax - because it is reading your data, not guessing at it.
Writes for you
Let AI handle the busywork
Draft a quote from a job description, write a quote or invoice overview, and tighten rough line items - without leaving Apsis.
Draft quotes
Describe the job; Apsis drafts the title, overview and itemised lines for you to edit.
Improve what you've written
Tighten a rough description into something clear enough to send.
Overviews
Turn a quote's or invoice's line items into a short overview for your client.
Reads your books
Ask your business a question
The answers are already in Apsis - you just shouldn't have to go digging through four screens to find them. Ask in plain English and Apsis looks it up in your own records.
- Who still owes me money?
- What did I spend on fuel last financial year?
- How is this month tracking against last?
- What's outstanding for my biggest client?
It can look, never touch. The assistant only reads, and only ever your own business - it can't change a document, a figure or a status.
Included on Plus: 50 AI drafts a month, and AI chat with its own monthly limit.

How to write a quote that wins work
Why speed beats polish, what belongs in a quote beyond the price, and how scope creep gets designed in or out before the job starts.
What must legally be on an Australian tax invoice
The exact fields the ATO requires on a tax invoice, the extra rule for sales from $1,000, and the details that get invoices paid faster.
How to get invoices paid on time
Late payment is a systems problem, not a personality problem. Payment terms that work, and a follow-up sequence you can run without dread.
