Can You Trust AI With Your Accounting
April 21, 2026
If you’ve Googled “WooCommerce or Shopify for UK business” recently, you’ve probably seen the same recycled comparison tables about loading speeds and app counts. None of that is what actually determines which platform is right for your business. What matters is your costs, your time, and whether the whole thing becomes a bookkeeping nightmare when you hit the VAT threshold.
So here’s an honest take from an accountant’s perspective rather than a web developer’s.
What You’re Actually Paying For
WooCommerce is free to install. Full stop. But “free” is doing a lot of heavy lifting there. You’ll still need hosting (typically £5 to £25 a month), a domain, an SSL certificate, and once you start selling seriously, a handful of paid plugins for VAT compliance, subscriptions, or better checkout flows. It adds up. The upside is you control exactly where the money goes and you’re not tied to a subscription that scales with your plan tier.
Shopify starts at around £25 to £39 a month on the Basic plan. That covers hosting, security, and updates. It’s all baked in, which is genuinely convenient. The catch for UK businesses is the payment processing fees. Use Shopify Payments, which is available in the UK, and you pay the card processing rate on your plan: 2% plus 25p per transaction on Basic, dropping as you upgrade. Use any other payment gateway and Shopify adds a platform transaction fee on top of whatever the gateway charges. That can quietly eat into margin if you’re not watching it.
The Bit Your Accountant Actually Cares About
Neither platform files your VAT return. Both will collect VAT at checkout if you set them up correctly, but the records still need to go somewhere: Xero, QuickBooks, Sage. And that connection is where things can get messy.
WooCommerce handles UK VAT rates natively (20% standard, 5% reduced, 0% zero-rated), but it doesn’t keep a proper audit trail without additional plugins. If you’re approaching the £90,000 VAT registration threshold or you’re already registered, you’ll need a solid integration to an MTD-compatible accounting package. Tools like Link My Books or A2X are commonly used to bridge the gap cleanly. They reconcile payouts, split out fees and refunds, and push everything to Xero or QuickBooks in a format that actually makes sense.
Shopify works the same way. It integrates well with Xero and QuickBooks directly, and the same third-party tools apply. On balance, Shopify’s accounting integrations tend to be slightly cleaner out of the box because the data structure is more predictable. There’s no risk of a plugin conflict scrambling your order records mid-quarter.
Where WooCommerce starts to cause real problems is when businesses grow and layer in more complexity. EU sales, digital products, multiple currencies: each one typically requires another plugin. After a few years you can end up with a setup that even the developer who built it struggles to explain. Your accountant will spend more time untangling it than they should.
Which One Should You Choose?
If you already have a WordPress site and you’re starting out, WooCommerce makes sense. The costs are lower in the early stages, it plays well with content-heavy businesses, and you’re not locked into a platform fee before you’ve proven the concept. Just make sure your accounting integration is set up properly from the start, because retrofitting it later is a pain.
If you’re building from scratch and your priority is getting up and running quickly without managing hosting, updates, and plugin compatibility, Shopify is the more straightforward choice. It’s not necessarily cheaper, but the time saved has a real value and your monthly accounts are usually cleaner as a result.
For businesses already doing meaningful turnover, say £200k or more, the platform you started on matters less than whether your accounting stack is properly connected. A WooCommerce store with a clean Xero integration is perfectly manageable. A Shopify store with payouts going unreconciled for months is a mess regardless of how slick the storefront looks.
A Few Things Worth Sorting Before You Launch
Whichever platform you go with, open a dedicated business bank account before your first sale. Mixing personal and business transactions might seem harmless at the start but it creates a genuine headache when your accountant is trying to pull together your year-end figures or reconcile a VAT quarter.
Connect your ecommerce platform to accounting software early, ideally before you hit £90,000 in taxable turnover. Once you’re VAT-registered, HMRC expects digital records from day one under Making Tax Digital. And don’t rely on the platform’s built-in reports for your VAT return. They’re useful for business decisions but they’re not designed to produce a compliant VAT calculation without a proper integration sitting behind them.
If you’re unsure how to set any of this up, or you’ve inherited a setup that nobody’s entirely sure is working correctly, it’s worth getting an accountant who works with ecommerce businesses involved early. The cost of sorting it properly upfront is almost always less than fixing it when HMRC comes asking questions. Get in touch with our team and we’ll take a look at what you’ve got.
