How does the Free UK Invoice Generator work?

Our Invoice Generator is designed to be simple and secure. You fill in your business details, your client's details, and the invoice items directly on the page. Once you click "Generate PDF Invoice", your web browser creates the PDF file instantly.

Crucially, none of the information you enter is ever sent to, or stored on, our servers. Everything happens on your own device, ensuring your business and client data remains completely private.

Is the information I enter into the tools saved anywhere?

No. We are committed to your privacy. None of the financial data you enter into any of the calculators (e.g., salary, profits, expenses) or the Invoice Generator is saved by our website.

Some features offer optional local storage to save you time. For example, the "Save my details for next time" checkbox on the Invoice Generator (shared with the Quote Generator), the Reminders feature, and the Rolling 12-Month VAT Threshold Tracker all use your browser's local storage. This data is stored only on your device (e.g., computer, phone, or tablet), not on our servers. You can clear this data at any time using the relevant "Clear" buttons within each tool.

How does the Reminders feature work?

The Reminders feature lets you set personal reminders for important business dates—like tax deadlines, VAT returns, contract renewals, or any custom date you need to remember.

Your reminders are stored in your browser's local storage, not on our servers. This means they're completely private to you and only accessible on the device and browser where you created them. If you clear your browser data or switch to a different device/browser, your reminders won't carry over.

You can manage all your reminders from the Reminders panel on the homepage—edit, delete, or clear them all at any time. The Companies House Deadline Calculator can also add your calculated accounts, confirmation statement, and Corporation Tax dates to the reminders with a single click.

Will my clients see "OwnBoss.co.uk" on the UK VAT or No VAT invoice?

No, your clients will never see "OwnBoss.co.uk" on any invoice. Our invoice generator is entirely free, and all generated UK invoices are fully unbranded.

Can I add my logo to personalise the UK invoice template?

Yes, you can easily upload your logo. It will be placed in the top left corner of the UK invoice template, allowing you to brand your business seamlessly.

Can I create a PDF UK invoice?

Absolutely! Our invoice generator provides a customisable, ready-made invoice template, enabling you to create and instantly download a PDF copy of your UK tax invoice.

Can I create a quote or estimate instead of an invoice?

Yes. The Quote & Estimate Generator creates a professional PDF headed "QUOTATION", with your logo, optional VAT, notes or terms, and a valid-until date (30 days by default) so your prices don't stay open-ended. It clearly states it isn't a VAT invoice or a demand for payment.

It shares your saved business details and logo with the Invoice Generator, so if you've saved them once, they're filled in automatically for both tools—and like everything else on the site, the quote is generated entirely on your device.

How do the Tax & Financial Calculators work?

Our calculators use the latest official data from HMRC (for the tax year specified on the calculator) and standard financial formulas to provide you with quick estimations. They are designed to give you a good idea of your potential tax liabilities and take-home pay. They also cover key business growth metrics like Return on Investment (ROI), Customer Acquisition Cost (CAC), and Inventory Turnover, helping you make smarter decisions as your business grows.

Please remember, these tools are for informational and estimation purposes only. They do not account for all individual circumstances (like student loans, pensions, or complex tax affairs) and should not be considered professional financial or tax advice. Always consult with a qualified accountant for formal advice.

What is the "Is It a Business Expense?" tool for?

This tool is a quick-reference guide to help you understand which common business costs are typically considered allowable, tax-deductible expenses by HMRC. Simply type in an expense (like "laptop" or "client coffee"), and the tool will provide a summary and explanation based on general rules.

It helps you make more informed decisions about your spending, but like our other tools, it's for guidance only. The rules can have nuances, so for specific or complex expense queries, consulting an accountant is always the best approach.

Can the tools help me keep on top of tax deadlines and thresholds?

Yes—there's a set of tools built exactly for that. The MTD for Income Tax Checker tells you if and when Making Tax Digital applies to you, the Side-Hustle Trading Allowance Checker shows whether your extra income needs reporting and which deduction saves you more, and the Rolling 12-Month VAT Threshold Tracker keeps a running total of your turnover against the £90,000 registration threshold, projecting when you'd cross it at your current pace.

For limited companies, the Companies House Deadline Calculator works out your next annual accounts, confirmation statement, and Corporation Tax dates from your incorporation date—and can add them straight to the Reminders strip so they're always visible when you visit. As with all our tools, everything stays on your device.

What tax year are the calculators based on?

All tax-related calculators (PAYE, Self-Employed, Corporation Tax, etc.) are clearly marked with the UK tax year they are based on. We update the rates and thresholds annually on April 6th—the official start of the new UK tax year. This ensures that our tools are always aligned with the latest HMRC rules and providing the most accurate estimations for the year ahead.
