Best Apps for Small Business (2026): 15 Picks
The apps that actually earn their subscription for a one- or two-person business — invoicing, payments, bookkeeping and admin, with real prices.
The best apps for small business owners cover five jobs: getting paid, keeping the books, communicating, marketing and staying organised. Most small businesses need one app per job, not a platform that does everything badly. Below are 15 picks, chosen on one test: would a sole trader or small team still use it in six months, and does it pay for itself?
Disclosure: InvoiceSonic is ours. Prices and free versions change, so check each vendor before signing up.
How to choose small business apps
Before downloading anything, decide what problem each app solves. A good app saves time every week, works on a mobile device and a laptop, and lets you add team members without rebuilding your setup. Free apps are a good start, but check what advanced features sit behind the paid tier and whether the free version limits users — some allow three users, others unlimited users.
Keep everything together where you can: apps that connect to your accounting software or cloud storage save more hard work than standalone tools.
Getting paid
1. InvoiceSonic — invoicing and quotes
Ours. Create invoices, quotes and receipts from a phone or browser, with tax fields for AU, NZ, US, UK and Canada, due dates and payment instructions, and no percentage taken on bank transfers. The free tier is real. It is not accounting — pair it with an accounting app below. See the invoice app for small business or start in the free invoice generator.
2. Square — card payments in person and online
Square's reader plus invoicing is a coherent package if customers pay face to face or by credit cards online. Processing fees apply per payment; check your country's rate.
3. Wise Business — international payments
If you invoice overseas clients, Wise's mid-market exchange rate and local account details beat a bank's currency spread. Worth it the moment you bill in a second currency.
Accounting and tax
4. Xero — accounting software
The default in Australia and New Zealand and strong elsewhere. Bank feeds, reconciliation and tax reports. Buy it when you have GST/VAT obligations or a bookkeeper, not before.
5. QuickBooks Online — accounting, strongest in the US
Similar to Xero with a larger US footprint and good expense tracking. If you only ever wanted to send invoices you are over-buying — see QuickBooks alternatives.
6. Hnry — tax handled for you (AU/NZ)
Hnry takes a percentage of income and handles income tax, GST and returns. Expensive as a percentage, cheap compared with getting tax wrong. Sole traders weighing options should read sole trader accounting software.
7. Dext or Hubdoc — receipt capture
Photograph a receipt and it reaches your accounting software categorised. The end of the shoebox.
Communication and customer management
8. Google Workspace — email and Google Drive
Email on your own domain is the cheapest credibility upgrade available, and Google Drive keeps shared files in one place.
9. Slack — team messaging
For small teams with more than two people, a shared channel beats scattered text messages. The free version keeps recent history.
10. HubSpot CRM — customer management
A free CRM for tracking leads, quotes and follow-ups. Useful once you have more prospects than you can remember; its sales tools and advanced analytics sit in paid tiers.
Marketing and social media
11. Canva — design
Logos, quote covers, flyers and social media posts. The free tier goes a very long way.
12. Mailchimp — email marketing
Simple email campaigns to past customers are one of the cheapest ways to get repeat work. Start on the free plan and pay only as your list grows.
13. Meta Business Suite — social media scheduling
Schedule Facebook and Instagram posts and reply to messages in one place, free.
Productivity tools and admin
14. Notion or Trello — job and project tracking
Job tracking that is not a spreadsheet. Either works; the one you actually open is the right one.
15. Calendly and 1Password — scheduling and security
Calendly removes the back-and-forth to book a site visit. 1Password stores every login and bank account detail securely and shares them with staff safely.
If you only pick three
Invoicing, a domain email, and receipt capture. That covers getting paid, looking professional and surviving tax time — a few things that sink small businesses when they go wrong. Everything else is optimisation.
Free business apps vs paid
Free business apps are enough for most sole traders in year one. Pay when a limit costs you time: more users, automation, or cash flow reporting. Review subscriptions every six months and cancel anything you have not opened.
Invoicing apps for sole traders and the self-employed
If you work alone, you do not need a full suite. Look at invoicing software for sole traders that saves client details and tracks payment, or the invoice app for freelancers if you bill from your phone. For accounting on top, see accounting software for the self-employed.
