BOOKKEEPING ABERDEEN
About Numbers Speak
My name is Kasia Williams, and I’m the heart behind Numbers Speak – a friendly bookkeeping service based in Aberdeen. With a background in business management, a passion for precision, and years of experience supporting tradespeople and creatives alike, I love helping sole traders feel more in control of their money.
Whether you’re a self-employed electrician feeling buried in paperwork, or a jewellery maker wondering how to price your products fairly – I’m here to make the numbers make sense. I offer services in both English and Polish, so you can talk money in the language you’re most comfortable with.
For me, bookkeeping isn’t just about spreadsheets – it’s about giving you the freedom to focus on your craft or trade, knowing your finances are in safe hands.
I work with Xero, Sage, and QuickBooks – and I offer friendly training too if you’d like to learn how to use them for your business.
Numbers Speak is about trust, simplicity, and treating you like a person, not a transaction. My clients often say they feel relieved and understood after working with me – and that’s exactly how it should be.
