If you’re a sole trader, you’ve probably been told you “need” cloud accounting software. Your accountant recommends it. Your bank offers it for free with your business account. HMRC’s Making Tax Digital now requires digital record-keeping. But what is cloud accounting, what does it actually do that a spreadsheet doesn’t, and do you really need it?
The short answer: if your qualifying income exceeds £50,000, you need some form of digital record-keeping and submission from April 2026 — but that doesn’t necessarily mean full cloud accounting. Spreadsheets plus bridging software satisfy HMRC’s requirements. Cloud accounting goes further: it automates bank feeds, categorises transactions, captures receipts, generates invoices, and gives you a real-time view of your profit and tax liability.
This guide explains what cloud accounting is, how it compares to the alternatives, what to look for, and when it’s worth paying for — with links to the detailed guides on this site for each topic that goes deeper.
1. What Is Cloud Accounting?
Cloud accounting is bookkeeping and accounting software that runs in your web browser or mobile app rather than on your local computer’s hard drive. Your financial records are stored on the provider’s servers and accessed online — the same way you access Gmail, online banking, or any other web-based service.
This is different from desktop accounting (software installed on your computer, like older versions of Sage 50 or QuickBooks Desktop), where your data lives on your hard drive and you can only access it from that machine. Desktop accounting is being phased out by most providers — Xero, QuickBooks Online, FreeAgent, and Sage’s current products are all cloud-based.
The key characteristics of cloud accounting:
- Access from any device — your phone, laptop, tablet, or a computer at your accountant’s office
- Automatic backups — your data is on the provider’s servers, not your hard drive, so a lost laptop doesn’t mean lost records
- API connections — the software can connect directly to your bank (via Open Banking), to HMRC (for MTD submissions), and to other tools like receipt capture apps or payment processors
- Real-time updates — your profit, tax estimate, and cash position update as transactions are categorised, not just when you do a year-end reconciliation
- Multi-user access — your accountant or bookkeeper can access the same data simultaneously without emailing files
2. Cloud Accounting vs Spreadsheets: What’s Different?
Many sole traders start with a spreadsheet — and for simple businesses, a spreadsheet is perfectly adequate. Here’s where cloud accounting differs:
| Feature | Spreadsheet | Cloud accounting |
|---|---|---|
| Cost | Free (Excel/Google Sheets) | £0–£30/month |
| Bank transaction import | Manual (download CSV, paste in) | Automatic (Open Banking feed) |
| Transaction categorisation | Manual | Semi-automatic (software learns patterns) |
| Receipt capture | Manual (type in details) | Photograph with phone app, OCR extracts data |
| Invoicing | Create manually in Word/Excel | Generate, send, and track within the app |
| MTD submission | Requires separate bridging software | Built in — submit directly from the app |
| Real-time profit view | Only when you update the spreadsheet | Updates automatically as transactions sync |
| Tax estimate | Calculate manually | Calculated automatically, updated in real time |
| Accountant access | Email the file back and forth | Grant login access, they view the same data |
| Backup | Your responsibility | Automatic (provider’s servers) |
| Data loss risk | High (lost laptop, corrupted file) | Low (provider handles redundancy) |
The core trade-off is cost vs automation. A spreadsheet is free but requires manual data entry for every transaction. Cloud accounting costs £0–£30/month but automates most of the data entry through bank feeds and receipt capture. For a sole trader with 20–30 transactions a month, the time saving is 2–4 hours/month. For a sole trader with 5 transactions a month, a spreadsheet may be faster.
3. Cloud Accounting vs Spreadsheet Bridging: The MTD Decision
With Making Tax Digital for Income Tax now mandatory for sole traders with qualifying income over £50,000, you need some digital tool. The question is which type:
Option A: Spreadsheet + bridging software
You keep your existing spreadsheet as your record-keeping tool and add bridging software that connects it to HMRC’s API. The bridging software submits your quarterly updates and final declaration; you keep your records in the spreadsheet as normal.
Pros: Cheap (£0–£100/year), familiar (you keep your spreadsheet), minimal learning curve Cons: Manual data entry for every transaction, no bank feed, no receipt capture, no real-time profit view, no invoicing, you maintain two systems (spreadsheet + bridge)
Best for: Sole traders with very simple income and expenses, few transactions, and no desire to learn new software. If you have one client, one bank account, and 10 transactions a month, this works fine.
Option B: Full cloud accounting
You move your record-keeping into the cloud accounting platform entirely. The software handles bank feeds, categorisation, invoicing, receipt capture, MTD submissions, and your final declaration — all in one system.
Pros: Automated bank feeds, receipt capture, real-time profit and tax estimates, invoicing, accountant access, single system for everything Cons: Costs £0–£30/month (though free options exist), learning curve to set up, you’re locked into a provider’s ecosystem
Best for: Sole traders with multiple income sources, regular transactions, VAT registration, or who want a real-time view of their business. If you have multiple clients, recurring expenses, or want to track profit monthly, cloud accounting pays for itself in time saved.

4. What Cloud Accounting Actually Does: The Five Core Features
If you’re new to cloud accounting, here’s what the software actually does day to day:
Bank feeds
The software connects to your business bank account via Open Banking and automatically imports transactions — usually daily. You don’t download statements or manually enter transactions. The software shows you each transaction and asks you to categorise it (e.g., “office supplies”, “travel”, “client payment”). Over time, it learns patterns: if you always categorise a payment to AWS as “software”, it starts suggesting that automatically.
This is the single biggest time-saver. Instead of typing in 50 transactions a month, you review and confirm 50 auto-imported transactions — a 5-minute task instead of an hour.
Receipt capture
Most cloud accounting platforms include a mobile app that lets you photograph a receipt with your phone. The software uses OCR (optical character recognition) to extract the supplier name, date, amount, and VAT, and creates an expense record from it. You snap the photo, confirm the details, and the receipt is filed digitally — no shoebox of paper.
Some platforms include this for free (Xero includes Hubdoc, FreeAgent has built-in receipt capture). Others require an add-on like Dext (~£25/month) for high-volume receipt processing.
Invoicing
You can create, send, and track invoices from within the software. Most platforms let you customise invoices with your logo, set up recurring invoices for retainer clients, and automatically chase late payments. When a client pays, the software matches the incoming bank payment to the invoice and marks it as paid — no manual reconciliation.
MTD submissions
For sole traders in scope for Making Tax Digital, HMRC-compatible software submits your quarterly updates and final declaration directly to HMRC through its API connection. You don’t need separate bridging software or a separate HMRC portal — you click “submit” within your accounting software and it sends the figures to HMRC.
The quarterly update is a summary of income and expense totals by category — not individual transactions. HMRC doesn’t see your receipts or invoice lines, just the category totals. For the full quarterly update process and deadlines, see our MTD quarterly updates guide.
Real-time profit and tax estimate
As you categorise transactions throughout the year, the software calculates your profit and estimates your tax liability in real time. This means you can see roughly what you’ll owe in January before January arrives — useful for budgeting and for deciding whether to make pension contributions or other tax-reducing moves before 5 April.

6. Do You Actually Need Cloud Accounting?
The honest answer: it depends on your transaction volume, your tolerance for manual data entry, and whether you’re in scope for MTD.
You need some digital tool if:
- Your qualifying income exceeds £50,000 (MTD mandatory from April 2026)
- Your qualifying income is £30,000–£50,000 (MTD mandatory from April 2027)
- Your qualifying income is £20,000–£30,000 (MTD mandatory from April 2028)
But “some digital tool” can be spreadsheet-plus-bridging software, not necessarily cloud accounting.
Cloud accounting is worth paying for if:
- You have more than 20–30 transactions per month — the bank feed automation saves 2–4 hours/month
- You invoice clients regularly — built-in invoicing and payment tracking is faster than Word + manual reconciliation
- You’re VAT-registered — cloud accounting handles VAT Returns through MTD for VAT as well as income tax quarterly updates
- You want a real-time view of profit and tax — useful for budgeting and year-end planning
- Your accountant needs access — cloud accounting lets them review and file without emailing files
- You have multiple income sources (self-employment + property, or multiple trades) — the software handles separate digital records for each
A spreadsheet plus bridging software is fine if:
- You have few transactions (under 20/month) — manual entry is faster than learning new software
- You have one income source and simple expenses
- You’re not VAT-registered
- You’re comfortable with spreadsheets and don’t want to learn a new interface
- You want to minimise cost — bridging software is £0–£100/year vs £0–£360/year for cloud accounting

7. The Cost: Software, Time, and Tax Relief
Cloud accounting costs range from £0 to £360/year. Here’s the full picture:
Software cost:
- Free options: FreeAgent (via qualifying bank accounts), Sage free tier, Acxite (spreadsheet bridging)
- Budget options: Xero Simple (£7–£18/month), Sage paid tier (£7/month), Starling Accounting Plus (£7/month)
- Standard options: FreeAgent direct (£19/month), QuickBooks (£10–£24/month), Xero standard (£18–£30/month)
Time cost:
- Initial setup: 2–4 hours (connecting bank feeds, setting up categories, importing opening balances)
- Ongoing: 15–30 minutes/month for a simple sole trader, 1–2 hours/month if you have many transactions or multiple trades
- First MTD quarterly update: allow extra time to verify your figures before submitting
Tax relief: The cost of accounting software is an allowable expense — you can deduct it from your taxable income, reducing your tax bill by 20–45% of the cost. A £20/month subscription costs £240/year, saving £48 at 20% tax or £96 at 40%. For the full rules on deducting software costs, see our MTD software costs as an allowable expense guide.
The net cost after tax relief is typically £0–£200/year for most sole traders — and it can be £0 if you use a free option.
8. Cloud Accounting and VAT: Two MTD Regimes
If you’re VAT-registered, you’re already subject to MTD for VAT — which has applied to all VAT-registered businesses since April 2022. You must keep digital records and submit VAT Returns through MTD-compatible software.
If you’re also in scope for MTD for Income Tax (qualifying income over £50,000 from April 2026), you have two separate digital reporting obligations:
| Obligation | Frequency | What’s submitted |
|---|---|---|
| MTD for VAT | Quarterly (VAT quarters) | VAT Return: output VAT, input VAT, net payable |
| MTD for Income Tax | Quarterly (tax year quarters) | Income and expense summary by category |
Most cloud accounting platforms handle both — your VAT Return and your income tax quarterly updates are submitted from the same software. This is a significant advantage over spreadsheet-plus-bridging, where you may need separate bridging tools for VAT and income tax.
For the full VAT registration rules and threshold, see our VAT registration for sole traders guide. For how both MTD regimes interact, see our Making Tax Digital guide.
9. Common Problems and How to Fix Them
“My software won’t connect to HMRC”
This is the most common MTD problem. The usual causes: you haven’t signed up for MTD for Income Tax with HMRC yet (a prerequisite), you’re using the wrong Government Gateway credentials, or your National Insurance number doesn’t match HMRC’s records. For the step-by-step fix (including the Starling Accounting case specifically), see our Starling Accounting MTD link failed guide — the troubleshooting steps apply to most software, not just Starling.
“My bank feed has stopped syncing”
Bank feeds use Open Banking connections that need re-authorising every 90 days. If your feed stops, log into your accounting software and re-authorise the connection. If it still doesn’t work, check whether your bank has changed its API or whether there’s a maintenance window.
“I can’t figure out which category to use”
Most platforms have default category mappings that cover the common sole trader expenses. If you’re unsure, use the closest match and ask your accountant at year-end. The key categories for sole traders: sales income, cost of sales, admin expenses (office, software, phone), travel, professional fees, and capital assets. For what’s deductible, see our reduce your Self Assessment tax bill hub.
“I entered something wrong in a previous quarter”
Under MTD, you can correct errors in subsequent quarterly updates for the same tax year. If the error is in a previous tax year, you may need to amend your final declaration or file an amendment. For the amendment process, see our made a mistake on your Self Assessment guide.
10. Cloud Accounting and Your Business Structure
If you’re a sole trader, cloud accounting handles your Self Assessment and MTD for Income Tax obligations. If you trade through a limited company, the same software can handle your Corporation Tax accounting, payroll (for your director salary), and VAT Returns — but MTD for Income Tax doesn’t apply to companies (they’re subject to Corporation Tax rules, and MTD for Corporation Tax has no firm date yet).
This means cloud accounting is useful regardless of your structure, but the specific features you need differ:
- Sole trader: Income/expense tracking, MTD for Income Tax quarterly updates, Self Assessment filing
- Limited company: Income/expense tracking, Corporation Tax accounting, payroll (RTI for director salary), VAT Returns, dividend tracking, Companies House filing (some platforms integrate this)
If you’re deciding between sole trader and limited company, see our sole trader or limited company guide. If you’re registering as self-employed for the first time, see our first-year self-employed checklist.
The Bottom Line
- Cloud accounting is online bookkeeping — it runs in your browser, stores data on the provider’s servers, and connects to your bank and HMRC through APIs.
- It’s not required for MTD — spreadsheet-plus-bridging software satisfies HMRC’s digital record-keeping rules. But cloud accounting makes MTD easier by handling both record-keeping and submission in one system.
- The main advantage is automation — bank feeds, receipt capture, and auto-categorisation save 2–4 hours/month for sole traders with regular transactions. For simple businesses with few transactions, a spreadsheet may be faster.
- Free options exist — FreeAgent (via qualifying bank accounts), Sage free tier, and Acxite (spreadsheet bridging) all cost £0. You don’t have to pay for software if your tax affairs are simple.
- The cost is tax-deductible — software is an allowable expense, reducing the net cost by 20–45% depending on your tax band.
- If you’re VAT-registered, you already need MTD-compatible software — cloud accounting handles both VAT Returns and income tax quarterly updates from the same platform.
- Most platforms handle multiple trades and income sources — useful if you have self-employment income plus property income, or multiple businesses.
