Why Accounting Software Is Essential

Modern accounting software has transformed bookkeeping for small businesses. What once required hours of manual data entry can now be done in minutes with automated bank feeds, receipt scanning, and real-time reporting. For UK businesses, there is an additional imperative: Making Tax Digital (MTD) requires VAT-registered businesses to use MTD-compatible software.

Making Tax Digital (MTD) Compliance

All VAT-registered businesses must use MTD-compatible software. All the paid options above (Xero, QuickBooks, FreeAgent, Sage, Zoho Books) are MTD-compliant. Wave is not.

From April 2026, MTD for Income Tax will require sole traders and landlords with income over £50,000 to use compatible software and submit quarterly updates. Ensure your chosen software will support this.

How to Switch Accounting Software

If you are switching from one software to another:

1. Export your data from your current software (chart of accounts, customer/supplier lists, opening balances)

2. Choose your switch date — the start of a new financial year or VAT period is easiest

3. Import your data into the new software

4. Set up bank feeds and reconcile

5. Test thoroughly before going live

6. Inform your accountant of the switch

Most software providers have migration guides

and customer support teams can assist with migration.

Frequently asked questions

Which accounting software do most UK accountants prefer?

Xero is the most popular accounting software among UK accountants, followed by QuickBooks Online. If you plan to work with an accountant, ask which software they prefer — using the same platform makes collaboration much easier and can reduce your accountant's fees. Many accountants offer discounted software as part of their service.

Is free accounting software good enough for a small business?

Wave is free and adequate for very simple businesses that are not VAT-registered. However, it is not MTD-compatible, which means VAT-registered businesses cannot use it for VAT returns. Zoho Books has a free tier that is MTD-compliant for businesses with turnover under £35,000. For most growing businesses, the cost of paid software (£15–£30/month) is easily justified by the time saved and features provided.

Do I need accounting software if I use a spreadsheet?

Spreadsheets work for very simple businesses, but accounting software is strongly recommended for most. The key advantages: automatic bank feeds save hours of data entry; MTD compliance for VAT; real-time profit and loss reports; easier collaboration with your accountant; invoice tracking and payment reminders; and receipt scanning. The time saved typically far exceeds the monthly cost.

Can I switch accounting software mid-year?

Yes, but it is more complex than switching at the start of a new financial year. You will need to enter opening balances and ensure all historical transactions are accounted for. Most software providers have migration guides. The start of a new financial year or VAT period is the easiest time to switch. Always inform your accountant before switching.

What is Making Tax Digital and which software supports it?

Making Tax Digital (MTD) is HMRC's programme to digitalise the tax system. MTD for VAT is already mandatory for all VAT-registered businesses — you must use MTD-compatible software to submit VAT returns. All the major paid accounting software options (Xero, QuickBooks, FreeAgent, Sage, Zoho Books) are MTD-compliant. Wave is not. For 2026/27, MTD for Income Tax applies from 6 April 2026 where qualifying income is above £50,000, with staged expansion planned above £30,000 from April 2027 and above £20,000 from April 2028.

Should I get accounting software before or after I register my business?

Set it up as soon as you start trading — ideally before your first transaction. Starting with good records from day one is much easier than trying to reconstruct them later. Many accounting software providers offer a free trial (typically 30 days), so you can test before committing. If you are not sure which to choose, start with Xero or QuickBooks — both are excellent and widely supported by UK accountants.
