What is Invoice Generator?
A professional invoice is more than a payment request — it is a legal document that records a commercial transaction, serves as evidence for accounting and tax purposes, and reflects the professionalism of your business. A well-structured invoice includes your business details (name, address, contact, tax registration number where applicable), client details, a unique invoice number (for your records and the client's accounts payable system), issue date, payment due date, itemised list of services or goods with quantities and unit prices, subtotal, tax (VAT, GST, or sales tax where applicable), and total amount due. Missing elements can delay payment (accounts payable teams often return incomplete invoices for resubmission) or cause tax compliance issues. This generator creates compliant, professional invoices that meet standard business requirements, with optional branding and automatic calculations.

Use Cases
Freelancer and Contractor Invoicing
Self-employed professionals and contractors need to invoice clients promptly and professionally. A correctly formatted invoice with clear payment terms (Net 30, bank details, late payment policy) significantly reduces payment delays compared to informal payment requests via email.
Small Business Client Billing
Small businesses without accounting software use this tool to generate invoices for client projects. The PDF output integrates easily into email workflows and provides a professional record of all billable work without the monthly cost of dedicated invoicing software.
Quick Quote-to-Invoice Conversion
After a client approves a quote, convert it directly to an invoice by updating the document type and adding the actual delivery date — maintaining consistent formatting and professional presentation throughout the client relationship.
Features
Professional PDF Output
Generates clean, professional PDF invoices formatted to standard A4 or US Letter, suitable for direct sending to clients or attaching to email.
Automatic Tax Calculation
Adds VAT, GST, or sales tax at configurable rates per line item or globally, with separate display of subtotal, tax amount, and total due.
Custom Branding
Upload your logo and set your brand colour to create invoices that match your business identity — more professional than generic black-and-white templates.
Saved Invoice History
Saves invoice history locally so you can reference past invoices, duplicate them for recurring clients, and maintain sequential invoice numbering automatically.
Frequently Asked Questions
Requirements vary by country, but a compliant invoice typically needs: your business name and address, client name and address, unique invoice number, invoice date, payment due date, description of goods/services, quantity and unit price per line item, subtotal, tax amount (with rate) if applicable, and total amount due. In the UK, VAT-registered businesses must also include their VAT registration number and show VAT separately. In the EU, invoices must comply with the Accounting Directive. Always include your payment details (bank account, PayPal, etc.) to enable prompt payment.
The most common B2B payment term is Net 30 (payment due 30 days after invoice date). Net 15 and Net 60 are also used. Shorter terms (Net 7, Due on Receipt) are standard for smaller transactions or new clients. Many businesses offer early payment discounts: "2/10 Net 30" means 2% discount if paid within 10 days, full amount due in 30 days. Late payment penalties (typically 1.5–3% per month or a fixed fee) should be clearly stated on the invoice and agreed in your client contract.
VAT registration and charging requirements depend on your country and annual turnover. In the UK, you must register for VAT once your taxable turnover exceeds £90,000 (as of 2024) and charge VAT on all invoices to UK customers from that point. Once registered, you must display your VAT number on all invoices. In the EU, VAT rules vary by country but broadly follow similar thresholds. In the US, sales tax rules vary by state. If you are below the threshold or B2B in a different country, VAT may not apply — but always verify with an accountant for your specific situation.
Prevention is most effective: clearly state payment terms on every invoice, send invoices promptly after delivery, and follow up with a polite reminder 3–5 days before the due date. For overdue invoices: send a firm payment reminder on the day it becomes overdue, follow up by phone if no response in 3 days, issue a formal overdue notice at 7 days. In the UK, the Late Payment of Commercial Debts Act entitles you to charge statutory interest (8% above base rate) and a fixed debt recovery fee (£40–£100 depending on invoice value) on overdue invoices — state this on your invoice.
