How We Work With You

Two Types of Business We Bookkeep For. Both Fully Managed.

Our bookkeeping service works for sole traders with straightforward accounts and limited companies with multiple revenue streams, payroll, CIS obligations, and regular VAT returns. The scope differs; the standard of accuracy does not.

Sole Traders, Freelancers & Landlords

Self-Employed & Rental Bookkeeping

MTD-Ready Digital records and quarterly updates from April 2026

From April 2026, sole traders and landlords earning above £50,000 must file quarterly digital updates under Making Tax Digital for Income Tax. We maintain your records in MTD-compatible software from day one so every submission is handled automatically, with nothing to scramble for at quarter end.

We also prepare your self assessment return, maximise every allowable expense, and keep records audit-ready year-round.

Limited Companies & Growing SMEs

Company Bookkeeping & Management Accounts

Full-Managed Monthly reconciliation, VAT, payroll and reporting

For limited companies, bookkeeping is the foundation your VAT returns, payroll, corporation tax, and dividend decisions all sit on. We handle every transaction, reconcile monthly, prepare quarterly VAT returns, and produce management accounts so you always know where the business stands.

We integrate directly with Xero or QuickBooks, connecting bank feeds, invoicing, and payroll in one real-time system.

Making Tax Digital for Income Tax: mandatory from April 2026Sole traders and landlords with income above £50,000 must use MTD-compatible software and file quarterly digital updates. The threshold falls to £30,000 in 2027 and £20,000 in 2028. Our bookkeeping service includes full software setup, data migration, and every quarterly submission as standard.

What Is Included

What Our Bookkeeping Service Covers

Bookkeeping is the systematic recording, categorisation, and reconciliation of every financial transaction in your business, maintained so that VAT filings, tax returns, and management decisions are always built on accurate, up-to-date data.

Day-to-Day Activities

  • Transaction recording and categorisation — every invoice, receipt, bank payment, and expense coded correctly under the right account and VAT treatment

  • Bank reconciliation — matching accounting records to bank statements monthly, identifying discrepancies before they compound

  • Accounts receivable and payable — tracking outstanding invoices and bills so you always have a clear picture of cashflow

  • Expense management — capturing expenses in real time via receipt scanning and bank feeds, eliminating the year-end shoebox entirely

  • Payroll journals and CIS — recording payroll runs correctly and filing monthly CIS returns for construction businesses with subcontractors

Reporting and Compliance

  • VAT returns and MTD submissions — quarterly VAT calculations and scheme advice, filed via MTD-compatible software with full digital audit trails

  • Management accounts — monthly or quarterly profit and loss, balance sheet, and cashflow reports so you know where the business stands in real time

  • Year-end preparation — fully reconciled trial balances and accounts ready for statutory filing, reducing preparation time and cost

  • Software setup and migration — Xero or QuickBooks configured from scratch, including bank feeds, chart of accounts, and historical data import

  • HMRC correspondence — responding to VAT queries and reconciliation requests on your behalf as your authorised agent throughout the year

Our Bookkeeping Service

Everything Included in Our Managed Bookkeeping Service

Our bookkeeping service is fully managed and integrated with your wider accounting obligations, from daily transaction recording through to VAT returns, payroll, management accounts, and year-end preparation. See how it connects with our corporation tax service.

Bank Reconciliation

Monthly reconciliation of every bank account, credit card, and payment processor against your accounting records. We identify unmatched transactions and categorisation errors before they compound. Most businesses we onboard have months of unreconciled entries — we clear the backlog and keep it clean.

VAT Returns & MTD Filing

Quarterly VAT preparation and submission via MTD-compatible software. We advise on the most tax-efficient VAT scheme for your business and handle registration, deregistration, and scheme changes. All returns filed with full digital audit trails and HMRC confirmation.

Payroll & CIS Processing

Monthly payroll runs, payslip generation, and RTI submissions. For construction businesses, we manage subcontractor verification, CIS deduction calculations, monthly CIS returns, and subcontractor statements, including gross payment status applications.

Management Accounts

Monthly or quarterly profit and loss statements, balance sheets, and cashflow reports from your live bookkeeping data. Management accounts show whether you are profitable, how much VAT you owe, and whether retained profits support a dividend — before you make those decisions.

Year-End Preparation

Fully reconciled trial balances, year-end journals, accruals, prepayments, and fixed asset schedules, delivered ready for statutory accounts and CT600 filing. Because our bookkeeping feeds directly into our corporation tax work, there is no rekeying and no year-end catch-up charge.

Software Setup & Migration

Xero or QuickBooks configured from scratch with the right chart of accounts, bank feeds, VAT settings, and opening balances. We also clean up existing software where previous entries are inaccurate, which is far more common than business owners realise when first switching providers.

Ready Metal Co. Ltd

Edgar Costa

★★★★★

Used Protax for my first year in business. The process was so simple and smooth. I checked a few accountants before going with Muhammad and Protax. As a new business owner, accountants can be a little confusing — not only did the team do a lot for me, they also taught me a lot. Will be using Protax for as long as I am in business. Highly recommend.

Mick & Maria Cass

Why Choose Protax

Bookkeeping That Is Integrated, Accurate, and Actually Useful

Most businesses treat bookkeeping as a compliance task. Done properly, it is a live financial dashboard that tells you whether you can afford to hire, whether margins have shifted, and whether you have enough retained profit to pay a dividend safely. Muhammad Bilal ACCA and the Protax team have been delivering that standard for London SMEs for over 15 years.

  • We Integrate Bookkeeping With Your Tax Work

    When bookkeeping and corporation tax are handled by the same team, every coding decision in Xero feeds directly into your CT600, VAT return, and year-end accounts, eliminating the duplicate work most businesses pay for when their bookkeeper and accountant are separate firms.

  • MTD-Compliant From Day One

    We maintain records in MTD-compatible software as standard, regardless of your mandatory start date. When the requirement kicks in, nothing changes for you operationally. Businesses that wait and then scramble to digitise their records face a disruptive and expensive transition.

  • Management Accounts Directors Actually Use

    We produce monthly management accounts in a format directors find genuinely useful: profit against budget, cashflow projection, aged debtors, and a one-page summary. Clients who use them make better decisions on hiring, pricing, and dividend timing. Those who do not often find out too late.

  • Xero and QuickBooks Certified, Not Just Users

    Certification means correctly configuring chart of accounts, applying accurate VAT treatments, and producing reports that reflect how your business operates. The difference shows in the quality of categorisation, the accuracy of reconciliation, and the usefulness of every report produced.

  • Cheaper Than In-House, With No Employment Risk

    An in-house London bookkeeper costs £28,000 to £35,000 in salary before NIC, pension, and recruitment fees. Our outsourced service costs a fraction of that, scales with your transaction volume, and carries no employment risk. Most businesses that switch reduce bookkeeping costs by 40% or more in year one.

Common Questions

Bookkeeping Services: Frequently Asked Questions

For most London small businesses, outsourced bookkeeping costs between £120 and £500 per month on a fixed-fee basis, depending on transaction volume, whether payroll is included, and reporting frequency. Very small businesses and sole traders sit at the lower end; limited companies with VAT, payroll, and management accounts sit in the middle to upper range. This compares favourably to employing an in-house bookkeeper, which costs £28,000 to £35,000 per year in salary before employer National Insurance and pension. We quote based on your actual transaction volume after a brief initial conversation, so you know the cost before we start.
Yes. Accounting software automates certain tasks such as bank feed imports and invoice matching, but it cannot categorise transactions correctly, apply the right VAT treatment, or produce accurate management accounts without a qualified person making the underlying judgements. Software is only as accurate as the data going in. Most businesses we take over from DIY software users have months of miscategorised transactions, incorrectly treated VAT, and unreconciled accounts that produce misleading reports. We correct existing records and maintain them correctly going forward.
A bookkeeper records, categorises, and reconciles your day-to-day transactions throughout the year. An accountant uses those records to prepare statutory accounts, tax returns, and strategic tax advice. The quality of your accounting is directly limited by the quality of your bookkeeping: inaccurate or incomplete records mean the accountant cannot produce a reliable return without expensive clean-up. At Protax, we handle both under one roof, so the bookkeeping is done to the standard the accountant needs with no handover gap or rekeying cost between the two.
Yes. Our bookkeeping service includes quarterly VAT return preparation and submission as standard for VAT-registered businesses. Because VAT and bookkeeping are inseparable, each transaction must be coded with the correct VAT treatment before a return can be produced, we do not offer one without the other for the same period. We also advise on VAT scheme selection. For many small businesses, the flat rate scheme produces a lower VAT liability than the standard method; for others, cash accounting provides useful cashflow benefits. We model the right scheme for your business before recommending.
Making Tax Digital for Income Tax Self Assessment (MTD ITSA) requires sole traders and landlords with qualifying income above £50,000 to maintain digital records and submit quarterly updates to HMRC from April 2026. The threshold drops to £30,000 in 2027 and £20,000 in 2028. Under MTD ITSA, quarterly digital submissions replace the traditional single annual return and all records must be held in approved software. Our bookkeeping uses MTD-compatible software throughout, so all quarterly submissions are handled automatically. If you are approaching your mandatory start date and your records are not yet digital, we can migrate your data and set up the correct system before your deadline.
We typically onboard new bookkeeping clients within 3 to 5 business days. The process involves a short video call, software access and bank feed setup, and a review of your existing records. If you are mid-year with unreconciled accounts, we include a catch-up bookkeeping phase to bring records current before taking on the ongoing monthly work. For urgent situations such as an imminent VAT deadline or a bank requiring up-to-date management accounts, we can prioritise onboarding. Fill in the form above to begin.
