Meet Our Founder & Why We Stand Out

Hello! I’m Polina, the Founder and Director of Best-Assistant Accounting Ltd

With over a decade of experience in bookkeeping, payroll, and accounting, I am passionate about helping businesses thrive.

Our firm is based in Aylesbury, Buckinghamshire, but we proudly serve clients remotely across the country.

As a member of AAT, ICB, ACIPP, and a Certified Xero Payroll Advisor, I bring a wealth of knowledge and expertise to our clients. My journey in the world of finance has been driven by a love for numbers and a commitment to excellence. Beyond my professional life, I have a deep love for stand-up comedy, music, and reading. These interests keep me inspired and energised.

I also believe in giving back to the community and actively support several charities, including Great Ormond Street Hospital, A Child’s Wish, Breast Cancer Now, and Berks Bucks & Ox Wildlife Trust.

At Best-Assistant Accounting Ltd., we are dedicated to providing top-notch accounting services with a personal touch. We look forward to partnering with you and helping your business succeed.

Common Bookkeeping Challenges I Help Solve

Over the years, I have worked with startups, sole traders, subcontractors, consultants, landlords, and growing businesses that found keeping financial records organised increasingly difficult as their business expanded. Some of the most common bookkeeping challenges I help clients overcome include:

Falling Behind On Financial Records

Many businesses simply do not have enough time to keep bookkeeping fully up to date alongside running day-to-day operations.

Missing Visibility Over Spending

Without accurate bookkeeping, it becomes difficult to understand where money is being spent and how profitable the business really is.

Unreconciled Bank Transactions

Bank transactions can quickly build up, making it harder to identify errors and maintain accurate records.

Preparing For Tax Deadlines

Incomplete records often create unnecessary pressure when VAT returns, year-end accounts, or tax deadlines approach.

The Benefits Of Up-To-Date Bookkeeping

Accurate bookkeeping provides much more than compliance. It helps business owners understand cash flow, monitor spending, prepare for tax obligations, and make informed decisions based on reliable financial information.

Many clients tell me that one of the biggest benefits is simply having confidence that their records are organised and up to date.

 

What They Say About Me

Clients trust Best-Assistant Accounting Ltd because I stay personally involved with communication, advice, and ongoing support. I believe relationships matter in accounting, and I work hard to build long-term trust with every client.

Case Study: Helping A Local Business Get Its Records Back On Track

A business owner in Aylesbury approached me after falling several months behind with bookkeeping. Financial records were spread across invoices, receipts, bank statements, and spreadsheets, making it difficult to understand business performance.

After reviewing the records, I implemented a cloud-based bookkeeping system, organised more than 800 historical transactions, and introduced a structured monthly bookkeeping process. Within three months, administration time was reduced by approximately 25%, records were fully up to date, and the client gained a much clearer understanding of monthly income and expenditure.

The business owner now has accurate records available throughout the year and greater confidence when making financial decisions.

 

How Our Process Works
  1. Initial Review & Onboarding – I review your current records, bookkeeping processes, and software to identify any gaps and understand how your business operates.
  2. Setup & Integration – Where needed, I help optimise or implement bookkeeping systems such as Xero, QuickBooks, or Sage to improve accuracy and efficiency.
  3. Ongoing Bookkeeping – Your transactions, bank reconciliations, expenses, and financial records are maintained on a regular schedule to keep everything up to date.
  4. Reporting & Compliance – Regular reporting helps you stay informed, while organised records ensure you’re prepared for year-end accounts and HMRC requirements.
  5. Ongoing Support – As your business grows, I remain available to answer questions and provide bookkeeping support whenever you need it.
