Bookkeeping and hiring a small business accountant in London solve different problems: bookkeeping keeps your day-to-day records organised, while an accountant uses those records to file returns, ensure compliance, and plan around your tax position.
Many business owners assume these are interchangeable. They’re not, and knowing the difference affects both your costs and your risk of getting something wrong.
This guide breaks down what each actually covers, where they overlap, and how to decide what your business needs right now.
What Bookkeeping Actually Covers
Bookkeeping is the ongoing process of recording financial transactions as they happen.
This typically includes:
● Recording sales and income as they’re received
● Logging expenses and keeping digital copies of receipts
● Reconciling bank statements against recorded transactions
● Tracking invoices sent and payments received
● Maintaining organised, up-to-date financial records
Bookkeeping doesn’t involve filing tax returns or offering tax advice. It creates the accurate data that makes those tasks possible later.
What a Small Business Accountant Actually Covers
A small business accountant in London uses bookkeeping data to handle compliance and strategic decisions.
This typically includes:
● Preparing and filing annual company accounts with Companies House
● Completing self assessment return filing or Corporation Tax returns
● Managing VAT return filing if the business is VAT registered
● Running payroll processing for directors and employees
● Advising on tax-efficient structuring and planning
● Interpreting financial data to guide business decisions
An accountant’s work depends heavily on the bookkeeping behind it. Poor records make even a good accountant’s job harder and more expensive.
Where the Two Overlap
Some providers offer both services together, which is part of why the distinction gets blurred.
Many accounting firms now include bookkeeping as part of a bundled package, particularly for small businesses that don’t need a dedicated in-house bookkeeper.
The key difference isn’t who provides the service, but what the service actually does. Bookkeeping records what happened. Accounting interprets it, reports it, and plans around it.
Can You Do Bookkeeping Yourself?
For a very simple, low-volume business, yes, at least initially.
Basic spreadsheets or entry-level accounting software can handle straightforward bookkeeping when transaction volume is low and the business structure is simple, such as an early-stage sole trader.
The challenge is consistency. Bookkeeping done sporadically, rather than regularly, tends to create more work later when everything needs reconciling at once.
When DIY Bookkeeping Stops Being Enough
A few signs suggest it’s time to hand bookkeeping over to someone else.
1. Transaction volume increases — more sales and expenses mean more room for error and more time required
2. You register for VAT — this adds reporting requirements that benefit from consistent, accurate records
3. You hire staff — payroll needs to be accurate and properly integrated with your books
4. You’re preparing for funding or a loan — lenders expect clean, credible financial records
5. You’re spending more time on books than on the business — this is usually the clearest sign of all
Reaching any of these points doesn’t mean bookkeeping has failed. It usually just means the business has grown past what a simple system can handle well.
Making Tax Digital: Why This Distinction Matters More From 2026
Making Tax Digital for Income Tax is changing how sole traders and landlords are required to keep records.
From 6 April 2026, anyone with qualifying income over £50,000 must keep digital records and submit quarterly updates through compatible software, according to official GOV.UK guidance. This threshold drops to £30,000 from April 2027 and £20,000 from April 2028.
This shift makes consistent, digital bookkeeping a legal requirement for a growing number of businesses, not just good practice. Traditional paper records and once-a-year filing will no longer be accepted once someone falls within scope.
For many affected business owners, this is the point where working with a tax accountant in London who understands both bookkeeping and compliance becomes far more valuable than managing the transition alone.
Cost Comparison: Bookkeeping vs Full Accounting Support
Costs vary depending on scope, but the two services are typically priced differently.
| Service | Typical Pricing Basis |
| Bookkeeping only | Priced by transaction volume or monthly retainer |
| Self assessment filing | Fixed fee, typically from around £199 |
| Annual company accounts | Fixed fee, typically from around £299 |
| VAT return filing | Per quarter, typically £75–£250 |
| Combined bookkeeping and accounting package | Bundled fixed fee, often cheaper than paying separately |
Bundling both services with one provider often costs less than paying for bookkeeping and accounting separately, since less duplicate work is involved.
How to Decide What Your Business Needs
A simple way to think about it: bookkeeping is about keeping the data accurate, and accounting is about using that data correctly.
If your business is small, simple, and you have time to stay consistent, DIY bookkeeping paired with occasional accountant support for filing may be enough.
If your business is growing, VAT registered, employing staff, or approaching Making Tax Digital thresholds, a combined service with ongoing accountant support becomes far more practical.
FAQ
Is a bookkeeper the same as an accountant?
No. A bookkeeper records financial transactions. An accountant uses that data to prepare returns, ensure compliance, and offer tax planning advice.
Can I do my own bookkeeping and still hire an accountant just for tax returns?
Yes, this is a common and often cost-effective setup, as long as your records are accurate and organised enough for the accountant to work with.
Do I need bookkeeping software, or can I use spreadsheets?
Spreadsheets can work for very simple businesses, but Making Tax Digital requirements mean many businesses will need compatible software going forward.
How much does bookkeeping cost for a small business?
Pricing usually depends on transaction volume rather than a flat fee, though bundled packages with accounting services are often more cost-effective.
What happens if my bookkeeping is inaccurate?
Inaccurate records can lead to incorrect tax returns, missed expense claims, or compliance issues, and often cost more to fix later than to get right initially.
When does Making Tax Digital for Income Tax become mandatory?
From April 2026 for qualifying income over £50,000, expanding to £30,000 from April 2027 and £20,000 from April 2028.
Should a startup handle its own bookkeeping?
It’s possible in the very early stages, but many startups benefit from setting up proper bookkeeping systems from day one to avoid problems as transaction volume grows.
Is it cheaper to bundle bookkeeping and accounting with one provider?
Often, yes. Bundled packages typically cost less than paying separately, since the provider isn’t duplicating work reconciling someone else’s records.
Key Takeaways
● Bookkeeping records transactions; accounting interprets that data for compliance and planning.
● DIY bookkeeping can work for simple, low-volume businesses, but consistency is key.
● Growth, VAT registration, and hiring staff are common triggers for outsourcing bookkeeping.
● Making Tax Digital for Income Tax becomes mandatory from April 2026 for qualifying income over £50,000, making consistent digital records a legal requirement for more businesses.
● Bundled bookkeeping and accounting packages are often more cost-effective than separate providers.
Conclusion
Bookkeeping and hiring an accountant aren’t competing choices. They’re two parts of the same financial picture, and most growing businesses eventually need both. Understanding where one ends and the other begins helps you avoid paying for more than you need, or less than your business actually requires. If you’d like help figuring out the right setup, working with an experienced provider like Digifiling can help you combine both under one roof.
