10 Apps Every Sole Trader Should Have on Their Phone

The Accounted Editorial Team·1 March 2026·7 min read

Running a business from your phone used to sound a bit far-fetched. Now it's practically the norm. Whether you're a freelance designer working from a café, a plumber driving between jobs, or a dog walker juggling a packed schedule, your smartphone is your office, your filing cabinet, and your assistant all in one.

But with thousands of apps out there, which ones actually make a difference? We've rounded up the ten apps every sole trader should have installed in 2026 — tools that save time, reduce stress, and help you look thoroughly professional.

1. A Bookkeeping and Tax App

Let's start with the big one. If you're still tracking your income and expenses on a spreadsheet (or worse, a shoebox full of receipts), it's time for an upgrade. A good bookkeeping app lets you snap receipts, categorise transactions, and keep your records HMRC-ready all year round.

With Making Tax Digital for Income Tax now in full swing for sole traders earning over £50,000, having MTD-compatible software isn't optional — it's a legal requirement. And even if you're below the threshold, keeping tidy books makes Self Assessment infinitely less painful.

Accounted is purpose-built for UK sole traders, with features like automatic bank feeds, receipt scanning via Penny (our AI assistant), and built-in MTD submissions. It takes the faff out of bookkeeping so you can focus on actually running your business.

2. An Invoicing App

Getting paid starts with sending a proper invoice. A dedicated invoicing app lets you create professional-looking invoices in seconds, send them straight to clients, and track which ones have been paid.

Look for features like automatic payment reminders, recurring invoices for regular clients, and the ability to accept online payments. The faster you invoice, the faster you get paid — it really is that simple.

3. A Business Banking App

If you haven't already, separating your personal and business finances is one of the smartest moves you can make as a sole trader. Most business bank accounts now come with slick mobile apps that let you manage payments, set up standing orders, and even categorise spending on the go.

In 2026, the best business banking apps offer features like instant notifications, built-in invoicing, and integrations with accounting software. Whether you go with Starling, Tide, Monzo Business, or one of the traditional high street banks, make sure the app experience works for you — you'll be using it daily.

What to look for

Real-time transaction notifications
Easy payment and transfer functionality
Integration with your bookkeeping software
Low or no monthly fees (especially important when you're starting out)

4. A Receipt Scanning App

HMRC expects you to keep records of your business expenses, and "I definitely had the receipt somewhere" doesn't quite cut it. A receipt scanning app lets you photograph receipts the moment you get them, extracting the key details and storing everything digitally.

Some bookkeeping apps (including Accounted) have receipt scanning built in, so you may not need a separate app. But if yours doesn't, standalone options like Dext or Receipt Bank do the job nicely.

The important thing is to scan receipts immediately. The longer you leave it, the more likely that crumpled bit of paper ends up in the washing machine. We've all been there.

5. A Time Tracking App

If you charge by the hour — or even if you don't — knowing where your time goes is incredibly valuable. Time tracking apps like Toggl, Clockify, or Harvest let you log hours against specific projects and clients, giving you a clear picture of how profitable each piece of work actually is.

This data is gold when it comes to pricing your services. You might discover that your favourite client's projects consistently take twice as long as you estimated, or that admin tasks are eating up more of your week than you realised.

Tips for making time tracking stick

Start the timer as soon as you begin a task (don't try to remember later)
Create clear project categories
Review your data weekly to spot patterns
Use the insights to adjust your pricing and workload

6. A Cloud Storage App

Gone are the days of emailing files to yourself. Cloud storage apps like Google Drive, Dropbox, or iCloud give you access to your important documents from anywhere — and they provide an automatic backup in case your phone takes an unexpected swim.

As a sole trader, you'll want easy access to things like contracts, proposals, insurance documents, and client files. Organise them into clear folders and you'll never find yourself scrambling to find that one document five minutes before a meeting.

Most cloud storage services offer a generous free tier, so there's really no excuse not to use one.

7. A Project Management App

Even if you're a one-person operation, project management apps can be a lifesaver. Tools like Trello, Asana, Notion, or Todoist help you keep track of tasks, deadlines, and client deliverables without relying on memory alone.

The beauty of these apps is their flexibility. You can use a simple to-do list for day-to-day tasks or set up more elaborate boards with deadlines, priorities, and checklists for complex projects.

Choosing the right tool

Trello — Great for visual thinkers who like drag-and-drop boards
Asana — Ideal if you collaborate with other freelancers or subcontractors
Notion — Perfect for those who want an all-in-one workspace
Todoist — Best for straightforward task management without the bells and whistles

8. A Communication App

Whether it's WhatsApp Business, Slack, or Microsoft Teams, having a dedicated communication channel for work keeps things professional and stops client messages from getting buried between family group chats and memes.

WhatsApp Business is particularly popular with sole traders because most clients already use WhatsApp. You can set up a business profile, create quick replies for common questions, and even set away messages for when you're off the clock.

If you work with other freelancers or subcontractors regularly, Slack is worth considering. It keeps conversations organised by channel and integrates with dozens of other tools.

9. A Social Media Scheduling App

If social media is part of your marketing strategy (and in 2026, it probably should be), a scheduling app saves you from the daily scramble of thinking up posts on the spot. Tools like Buffer, Later, or Hootsuite let you plan and schedule content in advance across multiple platforms.

The real benefit isn't just saving time — it's consistency. Regular posting builds your online presence and keeps you visible to potential clients. Batch-create your content once a week and let the scheduler handle the rest.

Getting the most from social media

Focus on one or two platforms where your ideal clients actually spend time
Share a mix of helpful tips, behind-the-scenes content, and client results
Engage with comments and messages promptly
Don't stress about perfection — authenticity beats polish every time

10. A Password Manager

This might not be the most exciting app on the list, but it could be the most important. As a sole trader, you'll accumulate dozens of logins — banking, HMRC, email, client portals, software subscriptions, and more.

A password manager like 1Password, Bitwarden, or LastPass generates strong, unique passwords for every account and stores them securely. You only need to remember one master password. It's faster, safer, and means you'll never have to click "forgot password" again.

Considering the growing threat of cyber attacks on small businesses, this is one app that pays for itself many times over.

Honourable Mentions

A few more apps that didn't quite make the top ten but are well worth considering:

Canva — For creating professional graphics, social media posts, and marketing materials without design skills
Google Maps / Citymapper — Essential for sole traders who travel to client sites (and don't forget to track your mileage for tax purposes)
Scanner Pro — For digitising contracts, agreements, and other paper documents
Calendly — For letting clients book appointments without the back-and-forth emails

The Bottom Line

You don't need all ten of these apps from day one. Start with the essentials — bookkeeping, invoicing, and banking — and add others as your business grows and your needs evolve. The goal isn't to fill your phone with apps you'll never open; it's to build a toolkit that genuinely makes your working life easier.

The best app is the one you actually use consistently. So try a few options in each category, find what clicks with your workflow, and stick with it.
