The Essential Software Stack for a New Australian Small Business
Software is one of the first real costs a new business hits, and it's where plenty of owners quietly burn money before they've invoiced a single customer. The truth is you need surprisingly few tools to run a professional operation — about eight categories, most with a free or cheap option that will carry you well past your first year. Here's what belongs in your stack, roughly what each piece costs in Australia right now, and where you can safely spend nothing.
The golden rule: start lean
Every subscription you sign up for is a small recurring leak. Ten "only $15 a month" tools is $1,800 a year — money a new business could spend on stock, marketing or an accountant. So before you add anything to the stack, apply three tests: does it do a job nothing else in your stack already does, will you use it weekly, and can you start on the free tier? Pick one tool per job, prefer tools that connect to your accounting software, and review the lot every quarter. Cancelling an unused subscription is the easiest cost cut you'll ever make.
1. Accounting software
The non-negotiable one. Good accounting software tracks income and expenses, handles GST, generates the numbers for your BAS, and runs Single Touch Payroll if you hire staff. Doing this in a spreadsheet works until it very suddenly doesn't — usually at BAS time.
Your main options in Australia are Xero (Ignite plan, $37 a month), MYOB Business (Lite, around $26 a month billed annually) and QuickBooks Online (Simple Start, about $33 a month) — prices as at August 2026. Watch the fine print: some prices are quoted excluding GST, and promotional rates jump to full price after a few months. How the three compare on payroll, invoice limits and add-ons is covered in our guide to the best accounting software in Australia.
Budget pick: QuickBooks Simple Start — unless your accountant or bookkeeper works in Xero, in which case pay the few extra dollars and use what they use. The time they save flows straight back to you in lower fees.
2. Invoicing and payments
Here's the first place to avoid tool sprawl: your accounting software already does invoicing. You don't need a separate invoicing app — you need a way for customers to pay those invoices without posting you a cheque.
That means connecting a payment processor:
- Stripe — about 1.7% + 30 cents per domestic card transaction, GST inclusive (as at August 2026). Strong for online payments and subscriptions.
- Square — 1.6% for in-person payments and 2.2% online (as at August 2026), with no monthly fee.
- Bank-provided options — your business bank likely offers merchant facilities; compare the rates, because they're not always cheaper.
Budget pick: whichever processor plugs into your accounting software — usually Stripe or Square. Yes, the percentage stings, but a "pay now" button on your invoices gets you paid dramatically faster, and getting paid faster matters more to a new business than almost anything. See our cash flow management guide for why.
3. Point of sale (retail and hospitality only)
Skip this section entirely if you're a service business. If you sell in person, a POS system handles the register, receipts, basic inventory and end-of-day reporting.
- Square POS — the software is free; you pay $65 (as at August 2026) for the card reader and the 1.6% in-person transaction fee. Free plans also cover basic retail and restaurant modes.
- Lightspeed and other specialist retail/hospitality platforms — far deeper inventory and table management, but expect to pay a meaningful monthly subscription. Check current pricing on the vendors' sites before committing.
Budget pick: Square. Start on the free software with the cheap reader, and only move to a specialist platform when you genuinely hit Square's limits — most new businesses never do.
4. Email and documents
Sending quotes from a Gmail or Hotmail address costs you credibility. A business email on your own domain, plus shared documents, spreadsheets and cloud storage, comes from one of two providers:
- Google Workspace — Business Starter is about $11 per user per month on an annual plan (as at August 2026). Gmail, Docs, Sheets, Meet and 30GB of storage.
- Microsoft 365 — Business Basic is about $10–11 per user per month plus GST on an annual plan (as at August 2026, after Microsoft's July 2026 price rise). Web versions of Word and Excel, Outlook, Teams and 1TB of OneDrive storage.
Budget pick: either — this is a coin flip decided by what you already know; the two now cost much the same. If you've lived in Word and Excel for years, Microsoft 365 Business Basic is the familiar choice. If you want the simplest possible admin experience, Google Workspace wins.
5. Website and domain
Two separate purchases people often confuse. The domain (your web address) costs roughly $10–30 a year for a .com.au (as at August 2026) — you'll need an ABN to register one. The website itself can be a DIY builder:
- Wix — plans from about $17 a month billed annually (as at August 2026); you'll need the Core tier or above to take payments online.
- Squarespace — from roughly $17–25 a month depending on billing cycle (as at August 2026), with cleaner templates and less clutter.
- WordPress with cheap hosting — the most flexible and potentially cheapest option, but budget your own time for maintenance.
Budget pick: before you spend anything, set up a free Google Business Profile — for local service businesses it often drives more enquiries than the website does. Then buy the domain immediately (they're cheap, and losing your business name to someone else isn't) and start with a basic one-page site on Wix or Squarespace.
6. Scheduling and booking
If customers book time with you — consults, trades quotes, haircuts, classes — a booking tool kills the "does Tuesday work? No? How about Thursday?" email chain.
- Calendly — the free plan covers one event type and one calendar; the Standard plan is about US$10 a seat per month (as at August 2026, billed in US dollars).
- Square Appointments — genuinely free for a single staff member, including reminders and a basic booking page; the Plus plan is $40 a month per location (as at August 2026).
Budget pick: the free tier of either. Square Appointments if you also take payments through Square (bookings and payments in one place), Calendly for everyone else.
7. E-signatures
Chasing wet signatures on quotes and agreements is slow, and "print, sign, scan" is where deals go to die. Electronic signatures are legally recognised for most Australian business documents.
- Annature — an Australian provider with pay-as-you-go pricing at $1.75 per envelope (as at August 2026). No subscription; you pay only when you send something.
- DocuSign — the global default. Entry plans typically land somewhere between about $15 and $45 per user per month in AUD depending on tier — check current local pricing on their site.
Budget pick: Annature. A new business might send five documents a month — under $10, versus a subscription you barely use. This is the tool-sprawl principle in action: pay per use until volume justifies a plan.
8. Password manager
The unglamorous one that saves your bacon. By the time your stack is running you'll have a dozen logins, and reusing one password across all of them is how small businesses get breached.
- Bitwarden — free for personal use; the Teams plan is about US$4 per user per month (as at August 2026, billed in US dollars).
- 1Password — slicker interface, with business plans around US$8–9 per user per month (as at August 2026).
Budget pick: Bitwarden. Start on the free tier the day you start the business, and move to Teams when you hire. Turn on two-factor authentication for your accounting software, email and bank while you're at it.
What a lean stack actually costs
| Category | Budget pick | Rough cost (as at August 2026) |
|---|---|---|
| Accounting | QuickBooks Simple Start | ~$33/month |
| Invoicing and payments | Built into accounting + Stripe or Square | ~1.6–2.2% per transaction |
| POS (if needed) | Square | $65 reader, free software |
| Email and docs | Microsoft 365 Business Basic or Google Workspace | ~$11/user/month |
| Website and domain | Wix or Squarespace + .com.au domain | ~$20–30/month + ~$10–30/year |
| Scheduling | Calendly or Square Appointments free tiers | $0 |
| E-signatures | Annature | $1.75 per document sent |
| Password manager | Bitwarden | $0 to start |
Call it $70–90 a month for a solo service business, plus transaction fees. That's a professional, GST-compliant, secure operation for less than most people spend on takeaway coffee — and every line item is a deductible business expense (keep the invoices).
Key takeaways
- Eight categories cover almost everything a new Australian small business needs; a lean stack runs $70–90 a month plus payment processing fees.
- Accounting software is the foundation — choose it first, and choose what your accountant uses if you have one.
- Don't buy separate invoicing software; it's already in your accounting subscription. Just connect a payment processor.
- Free tiers (Square Appointments, Calendly, Bitwarden, Google Business Profile) are genuinely usable — start there and upgrade only when you hit a real limit.
- Prefer pay-as-you-go over subscriptions for anything you use occasionally, like e-signatures.
- Review your subscriptions quarterly and cancel anything you haven't opened in a month.
