The Best Apps for Sole Traders in the UK (Free and Paid)

There’s no shortage of apps promising to make self-employed life easier. The problem isn’t finding them — it’s working out which ones are actually worth your time and money, and which ones you’ll download, use twice, and forget about.

I’m Anita — a Chartered Accountant who’s been self-employed for most of my working life. These are the apps I’d recommend to a sole trader starting out today: the ones that genuinely save time, reduce stress, or keep more money in your pocket.

I’ve kept the list focused. You don’t need twenty apps — you need five or six good ones that you’ll actually use.

The Short List of Best Apps for Sole Traders (UK) at a Glance

Accounting Apps

Xero — Best Accounting App for Sole Traders

If you only download one paid app as a sole trader, make it accounting software — and Xero is the one I’d point most people towards.

On your phone, the Xero app lets you raise and send invoices instantly, reconcile bank transactions, capture receipts with your camera, and check your cashflow in real time. It’s fully Making Tax Digital compliant, which matters if you’re above the MTD income threshold — or will be soon.

The bank feed feature is the one clients tell me they couldn’t go back from. Link your business bank account and transactions import automatically — no manual data entry, no missing transactions come January.

Pricing: From £16/month (Ignite plan). Not free — but it saves enough time to pay for itself.

Club deal: Members of The Self Employed Club get 90% off Xero for 6 months — the Ignite plan for £1.60/month while you get started. Grab the deal →

Also worth considering:

• FreeAgent — free if you bank with NatWest or Mettle; solid alternative to Xero
• QuickBooks — strong mobile app, good for sole traders who do most of their admin on the go

Banking Apps

Starling Bank — Best Free Business Banking App

A separate business bank account is one of the best habits you can build as a sole trader — and Starling’s app makes it genuinely effortless.

Everything is done from your phone: instant payment notifications, spending categorisation, tax savings pots (genuinely useful for setting aside your tax bill), and direct integration with Xero, FreeAgent, and QuickBooks. No monthly fees, no minimum balance, FSCS-protected up to £85,000.

The “Spaces” feature is the one I’d highlight specifically: you can ring-fence money for your tax bill, for a specific project, or for a rainy day — all within the same account. Far better than trying to remember not to spend money you owe HMRC.

Pricing: Free for the standard business account.

Also worth considering:

• Tide — quick to set up, built-in invoicing, regular new account incentives
• Mettle — free NatWest account with FreeAgent included; good value if you’d use both
• Monzo Business — familiar interface if you already use Monzo personally; paid plan unlocks the best features

Invoicing Apps

Xero / FreeAgent / QuickBooks (above)

If you’re using accounting software, invoice directly from it — no need for a separate app. Xero, FreeAgent, and QuickBooks all have solid invoice functionality built in.

Zoho Invoice — Best Free Standalone Invoicing App

If you’re not ready for full accounting software yet and just need to send professional invoices, Zoho Invoice is genuinely free with no catch — unlimited invoices, client reminders, and basic reporting at no cost.

Pricing: Free.

Receipt Capture Apps

Dext — Best App for Capturing Receipts

The biggest admin habit change most sole traders need to make: photographing receipts immediately rather than hoarding them in a drawer and reconstructing everything at tax time.

Dext (formerly Receipt Bank) is the market leader for receipt capture. Point your camera at a receipt, and it extracts the data — supplier, amount, date, category — and pushes it directly into your accounting software. It integrates natively with Xero, QuickBooks, and FreeAgent.

The alternative: most accounting apps (including Xero) have their own built-in receipt capture. It’s less powerful than Dext but perfectly adequate for most sole traders. Try the built-in option first — only add Dext if you find yourself processing a high volume of receipts.

Pricing: Paid, with a free trial.

Design Apps

Canva — Best Design App for Non-Designers

For social media graphics, proposal documents, presentations, invoices, and anything else that needs to look professional without costing you a designer, Canva is the answer.

The mobile app is excellent — you can put together branded graphics in minutes from your phone. Thousands of templates, all customisable. The free plan is genuinely useful; Pro unlocks the brand kit, background remover, and premium templates.

Pricing: Free (Pro from ~£10/month)

Club deal: Members of The Self Employed Club can access a discounted Canva Pro deal. See it here →

Time Tracking Apps

Toggl Track — Best Free Time Tracking App

If you bill clients by the hour, or you want to understand where your working time actually goes, Toggl is the simplest and most reliable option.

One tap to start a timer, one tap to stop. Categorise by client or project. Review reports weekly to see where your time went. The free plan is more than enough for most sole traders.

Pricing: Free for up to 5 users (generous for sole traders).

Also worth considering:

• Clockify — free time tracking with stronger reporting
• Harvest — time tracking with built-in invoicing; paid but well-regarded

Scheduling and Booking Apps

Calendly — Best App for Client Booking

If you have regular discovery calls, client meetings, or consultations, Calendly removes the back-and-forth of finding a time. Share your link, people book based on your availability, it adds to your calendar automatically.

The free plan covers one event type — sufficient for most sole traders. The paid plan adds more booking types, payment collection, and branding.

Pricing: Free (basic), from ~£8/month (standard)

Communication Apps

Zoom — Best App for Client Calls

The default for video calls with clients. The free plan allows unlimited one-to-one calls and 40-minute group meetings — sufficient for most sole traders’ needs.

Pricing: Free (40-minute group call limit), from ~£12/month for unlimited.

Slack — Best App for Team Communication

Only relevant if you work with subcontractors or VAs regularly. For a sole trader working entirely alone, it’s overkill. If you do have people working with you, Slack’s free plan handles most needs.

Password and Security Apps

1Password or Bitwarden — Best Password Manager

Not glamorous — but as a sole trader you’re responsible for your own security. A password manager means one strong password to remember, and unique secure passwords for every tool and account you use. Bitwarden is free and excellent. 1Password is paid and more polished.

This is the app most people don’t bother with until they get hacked. Don’t be that person.

Pricing: Bitwarden — free. 1Password — from ~£2.50/month.

What You Probably Don’t Need

A few apps worth skipping — at least to start with:

Expensive CRM software — most sole traders don’t need Salesforce or HubSpot. A well-maintained spreadsheet or Notion database handles client management perfectly well until you’re turning away work regularly.

Separate email marketing apps with paid plans — if you’re just starting to build an email list, Mailchimp or MailerLite’s free plans are more than enough. Don’t pay for a list of 200 people.

Multiple project management apps — pick one and use it consistently. Trello, ClickUp, or Notion all work. Switching between them doesn’t.

Every productivity app you see on TikTok — the best productivity system is the one you’ll actually use. Simple beats clever every time.

The App Setup Most Sole Traders Actually Need

If you’re just getting started and want a simple, functional setup:

1. Accounting: Xero (use the Club deal to start cheaply)
2. Banking: Starling (free, integrates with Xero)
3. Design: Canva (free plan to start)
4. Tasks: ClickUp or Trello (free)
5. Time: Toggl (free, only if you bill by the hour)

That’s it. Five apps, two of them completely free, one heavily discounted through the Club. You can always add to it as your business grows — but this covers the essentials for most sole traders from day one.
