How we support e-commerce businesses in Cardiff
Running an online shop means juggling inventory, customer service, marketing, and fulfilment. The last thing you need is to lose sleep over your bookkeeping or miss a VAT deadline. We work with e-commerce businesses across Cardiff and South Wales to keep your finances organised, compliant, and ready for growth.
Our process starts with connecting your sales channels and payment platforms to cloud accounting software like Xero or QuickBooks. That means your transactions flow in automatically, and we reconcile everything monthly or quarterly depending on your needs. You get accurate management accounts, clear visibility on profit margins, and HMRC submissions handled on your behalf.
We understand high transaction volumes, marketplace fees, and the quirks of selling online.
More information
E-commerce accounting is different from traditional retail. You might be processing hundreds of small transactions a day, selling across multiple platforms, and dealing with payment processor fees that eat into your margin. We're experienced with Amazon Seller Central reports, PayPal exports, Stripe settlements, and the VAT implications of selling to EU or international customers. If you've switched from a spreadsheet to something more robust, we'll help you make sense of it all.
Making Tax Digital means quarterly submissions to HMRC using approved software. We handle that for you, along with your annual accounts, Corporation Tax or Self Assessment returns, and any payroll if you've started taking on staff or paying yourself a salary. You'll also get proactive advice on what you can claim as expenses, how to manage cash flow during busy seasons, and when it makes sense to register for VAT or move to a limited company structure.
What you can expect
Monthly or quarterly bookkeeping: We reconcile your sales, refunds, fees, and expenses so your records are always up to date.
VAT and tax returns: Submitted on time, every time, with nothing left to chance.
Real-time financial visibility: Log in to your accounting software any time to see how your business is performing.
Fixed monthly fees: No surprises, no hourly billing. Just a predictable cost that scales with your business.
We work with online sellers across Cardiff, from startups shipping handmade goods to established brands turning over six figures. Whether you're based in Roath, Canton, Pontcanna, or anywhere across South Wales, our service is entirely cloud-based. That means phone calls, video chats, and shared access to your accounts without needing to visit an office.
If you've been managing your own books and it's starting to feel overwhelming, or if you've outgrown your current accountant, we're here to help. Book a free consultation and we'll talk through what support makes sense for your business.
