Accounting Software UK | Privacy-First & MTD-Ready

Accounting Software UK Small Businesses Trust to Stay in Control

Looking for accounting software UK sole traders, freelancers and small limited companies can actually rely on - without handing every keystroke to a third party or to HMRC before you're ready? WDI Billing is cloud accounting software built on a simple promise: your books stay yours. You record what you earn and spend, you prepare your figures whenever you like, and you press file only when you choose to. Nothing streams to HMRC automatically.

That last point matters more than most accounting software UK providers admit. Many tools quietly sync your data to the tax authority in the background the moment you enter it. WDI Billing doesn't. We call it Prepare mode, and it's the default for every new account.

Cloud accounting software built for UK small businesses

WDI Billing is genuinely cloud accounting software - access it from a laptop, phone or tablet, anywhere you have a browser, with your data encrypted and hosted on EU/UK infrastructure. But "cloud" shouldn't mean "someone else's rules for your data". We built WDI Billing specifically for UK small business accounting software needs: VAT, Self Assessment, Making Tax Digital, and the everyday reality of invoicing, chasing payments and tracking expenses without a finance department behind you.

There's no long onboarding call, no annual contract, and no per-invoice fee. You can be raising your first invoice within minutes of signing up.

Three modes: Records, Prepare, File

Every business using WDI Billing works across three modes, and you're always the one who decides what moves between them:

  • Records - log income, expenses, invoices and receipts as they happen. Nothing leaves this stage unless you take it further.
  • Prepare - the default mode. Your VAT return or Self Assessment figures are calculated and laid out ready to review. Still nothing has been sent anywhere.
  • File - when you're satisfied the numbers are right, you submit directly to HMRC. One deliberate action, not an automatic background sync.

This structure suits businesses of every size - from a sole trader doing their own books to a limited company whose accountant reviews figures before anything is filed.

Making Tax Digital, handled properly

If you're VAT-registered, or your income falls under Making Tax Digital for Income Tax, you need HMRC-recognised software that keeps digital records and supports the digital links MTD requires. WDI Billing does exactly that - see our dedicated Making Tax Digital software page for the full detail, or head straight to MTD VAT software if VAT returns are your priority right now. Already keeping records in a spreadsheet? Our MTD bridging software lets you keep the spreadsheet and add the digital link on top.

Everything a small business accounting software needs, in one place

Beyond MTD, WDI Billing covers the day-to-day tasks that actually eat your time:

  • Invoicing - professional invoices, payment reminders and online payment links. See invoicing software UK.
  • Bookkeeping - bank feeds, categorisation and reconciliation that live in Records mode until you're ready to act on them. See bookkeeping software UK.
  • Expense tracking - snap a photo of a receipt and let optional AI extract the details, or enter it manually - AI is opt-in, and the software works fully without it. See expense tracker app.
  • Mileage tracking - log business journeys and calculate allowable mileage claims. See mileage tracker.

Everything exports cleanly - your data, your format, no lock-in. If you ever want to leave, you take your records with you.

Built around how you actually work

Whether you're a sole trader charging by the hour or a small limited company with a couple of directors, WDI Billing adapts rather than forcing you into someone else's template:

  • Sole traders and the self-employed get streamlined Self Assessment prep and expense capture designed for a single-person business - see sole trader accounting software.
  • Limited companies sit outside Making Tax Digital for Income Tax, so the priority is control and collaboration rather than mandate urgency - see accounting software for limited company.

Working with an accountant or bookkeeper? Grant them break-glass access to review your figures in Prepare mode before anything is filed - collaboration on your terms, not a shared login with no boundaries.

How WDI Billing compares to other UK accounting software

Xero, QuickBooks, Sage, FreeAgent, FreshBooks and Wave are the names most UK small businesses have heard of. Each has genuine strengths - and each has trade-offs worth knowing before you commit. QuickBooks raised its UK prices in January 2026, which has pushed many small businesses to look for a cheaper, equally capable alternative. FreeAgent comes free with certain business bank accounts, which is attractive until you consider what it means for the independence of your financial data from your bank. We've written honest, feature-by-feature comparisons so you can judge for yourself:

If you're already using one of these and thinking about switching, our Xero alternative and QuickBooks alternative pages walk through what moving looks like, including exporting your existing data.

Straightforward pricing, in pounds

No per-invoice charges, no surprise add-ons, and no requirement to hit a paid tier just to keep basic records. If your turnover sits under the VAT threshold, you can legally run WDI Billing in Records and Prepare mode only, filing nothing until you choose to. See full plan details on our pricing page.
