The 12 Best Apps for Small Business Owners (2026)
The apps that actually earn their subscription for a one- or two-person business — invoicing, payments, bookkeeping and admin, with real prices.
Small-business app lists usually run to forty tools nobody has time to set up. This is twelve, chosen on a harder test: would a sole trader or two-person business still be using it in six months, and does it pay for itself? Disclosure: InvoiceSonic is ours.
Getting paid
1. InvoiceSonic — invoicing and quotes
Ours. Invoice, quote and receipt from phone or browser, tax handled for AU, NZ, US, UK and Canada, and no cut taken on payments. Free tier is real. It is not accounting — if you need a general ledger, pair it with something below. What it does.
2. Wise Business — international payments
If you invoice overseas clients, the mid-market exchange rate saves meaningfully against a bank's spread. Genuinely worth it the moment you bill in a second currency.
3. Square — card payments in person
The reader plus invoicing is a coherent package for anyone taking payment face to face. Around 2.6–2.9% + $0.30 per payment.
Bookkeeping and tax
4. Xero — accounting
The default in Australia and New Zealand and strong everywhere. Buy it when you have a bookkeeper or GST/VAT obligations, not before.
5. QuickBooks — accounting, bigger in the US
Same reasoning as Xero, different market share. If you only ever wanted to send invoices you are over-buying — see QuickBooks alternatives.
6. Hnry — tax handled for you (AU/NZ)
Takes a percentage and handles income tax and GST automatically. Expensive as a percentage, cheap compared to getting tax wrong.
Getting work done
7. Google Workspace
Email on your own domain is the cheapest credibility upgrade available. A business address instead of a gmail one changes how quotes are read.
8. Canva
Logo, quote covers, van signage mockups, social posts. The free tier goes a very long way.
9. Notion or Trello
Job tracking that is not a spreadsheet. Either works; the one you actually open is the right one.
10. Calendly
Removes the six-message back-and-forth to book a site visit. Pays for itself in recovered evenings.
Admin that stops being admin
11. Dext or Hubdoc — receipt capture
Photograph the receipt, it reaches your accounting software categorised. The end of the glovebox shoebox.
12. 1Password
Not exciting, and the single highest-value subscription on this list the first time a client portal login is needed and nobody can find it.
If you only pick three
Invoicing, a domain email, and receipt capture. That covers getting paid, looking professional and surviving tax time — the three things that actually sink small businesses. Everything else is optimisation.
