Pricing — the QuickBooks pricing reality
QuickBooks publishes attractive starting prices but most UK SMEs find themselves climbing the tier ladder fast. The £14/mo Simple Start has no multi-user, no projects, no inventory. Most growing businesses end up on Essentials (£30/mo) or Plus (£42/mo). And there's a regular pattern of Intuit raising prices on existing customers each year.
Luca's £20/month hosted plan includes everything in one tier. There are no usage caps to push you up, no feature paywall mid-year price hikes.
The US-first problem
QuickBooks is built around US accounting practices. UK features (CIS, Construction Industry Scheme; specific HMRC quirks; British English in reports) feel bolted on. Things that should be one click sometimes take three.
Luca is UK-first. Built in Macclesfield, designed around UK SME accounting from day one.
AI — Intuit Assist vs Luca
Intuit launched "Intuit Assist" as their AI feature set in 2023-2024. It helps with: writing invoice descriptions, summarising reports, classifying some transactions. It's a useful copilot bolted onto a traditional accounting product.
Luca is built differently. Bookkeeping happens automatically through Claude calling Luca's tools — you check what's been done, you don't do it. It's a different relationship to your books.
Who QuickBooks suits
- You're a US business or operate primarily in the US
- You want the security of a $200B public-company vendor
- You need QuickBooks-specific add-ons (e.g. integrations only built for QuickBooks)
- Your accountant insists on QuickBooks and won't change
Who Luca suits
- You're a UK SME — sole trader, limited company, micro-business
- You want bookkeeping done for you, not just easier to do
- You value open source and data ownership
- You're tired of QuickBooks pricing creep
- You want a UK indie company you can actually talk to
Migrating from QuickBooks
QuickBooks Online supports CSV exports for chart of accounts, contacts, invoices, bills and bank transactions. Luca imports these directly. Migration usually takes 2-4 weeks for a typical SME.
FAQ
Will Luca work with my UK accountant who uses QuickBooks?
Yes. Luca exports trial balance, journals and P&L in standard formats your accountant can audit and file from. They don't need to learn Luca's UI.
Does Luca handle CIS for the construction industry?
Not natively in beta. CIS is on the roadmap. If you need CIS today, stay on QuickBooks or Sage, or use Luca for the rest of your books and a CIS-specific tool for that workflow.
Is there a free trial?
You can self-host Luca free forever (open source). For the hosted plan, contact us — we usually offer a free first month if you're migrating from another tool.
