Invoicing software for UK businesses

Making Tax Digital, properly.

MTD VAT has been mandatory for every VAT-registered business since April 2022, regardless of turnover. The HMRC requirement is unambiguous: VAT records must be kept digitally, and returns must be submitted via a recognised software digital link — no manual upload from a spreadsheet at the end of the quarter. Our integration uses HMRC's MTD API directly. The receipt and reference number land back in the platform, attached to the period, so you have an audit trail when (not if) HMRC asks for one.

VAT done right.

Three rates, not one. Standard 20% applies to most goods and services. Reduced 5% covers domestic gas and electricity, sanitary products, children's car seats, and a handful of energy-efficiency installations. Zero-rate 0% — distinct from exempt — covers most food, books, newspapers, children's clothes, and public transport. Exempt categories (financial services, insurance, education, healthcare) sit outside the VAT system entirely and do not contribute to the £90,000 registration threshold. We track all of this per line item, per invoice, with the right Box 6 and Box 7 numbers ready for your return.

Sole traders to limited companies.

The UK runs on a long tail of small businesses. Sole traders file Self Assessment (deadline 31 January for the previous tax year, which ends 5 April — not 31 December). Partnerships file a partnership return and individual partners file Self Assessment. Limited companies file a Corporation Tax return with HMRC and accounts with Companies House, on different deadlines. We auto-import legal name and registered office for UK Limited companies from Companies House, set up the right entity type at onboarding, and flag VAT treatment correctly per transaction. The output supports your accountant rather than fighting them.

Post-Brexit, without the headaches.

The UK left the EU VAT system on 1 January 2021. Sales to EU consumers are now exports — zero-rated UK VAT, with the customer paying import VAT on arrival. Businesses based in Northern Ireland still operate within the EU VAT regime for goods (the Windsor Framework / Northern Ireland Protocol) and can use the OSS (One Stop Shop) for cross-border distance sales. B2B services to EU businesses use the reverse charge — your customer accounts for VAT in their own country. We handle all three flows correctly, without forcing you to learn the exception list.

Pounds, primarily. Other currencies, properly.

GBP is the default on your invoices, dashboards and exports (your 4invoices subscription itself is billed in EUR). For multi-currency businesses, we support invoicing in USD, EUR, CAD, AUD with HMRC-compliant FX conversion at the invoice date (not today's rate). Bank reconciliation runs through Open Banking with FCA-regulated Account Information Service Providers — no screen-scraping, no third-party password storage. Penny rounding follows HMRC's published guidance: round to the nearest penny per line item, accumulate to the invoice total, never round the VAT down to avoid a £0.01 mismatch with the customer's books.

Quietly British.

Colour, not color. Organisation, not organization. Cheque, not check. Programme, not program. Dates as DD/MM/YYYY by default, addresses with the postcode on its own line at the end. Currency formatting £1,234.56 with the symbol before the number and no space. None of this is a tickbox feature — it's how the product reads from the moment you land on the homepage. Worth noting because Canadian and Australian software vendors rarely get it right, and US vendors don't try.

The UK is not a market we're testing for fit. It's a market we're committed to. Our 2026 roadmap covers expanded MTD ITSA support for sole traders crossing the £50,000 trigger, deeper Open Banking integration with Tide, Monzo Business and Starling, and connection to HMRC's e-invoicing pilot when it goes live. If your business operates here, we want to be the platform you grow with — without ever asking you to translate "checkout" into "trolley".
