How to Create an Invoice with This Tool
Fill in your business information (name, address, email, phone) and your client's details. Enter an invoice number (e.g., INV-001), issue date, and due date. Add line items by clicking 'Add Item' — each item has a description, quantity, and unit price. The subtotal, discount, tax, and total update automatically as you type. Your invoice data is auto-saved to browser storage so you can close the tab and return later without losing progress.
When your invoice is ready, use the Print button to open your browser's print dialog — print to PDF to create a shareable file. Alternatively, use Copy as Text to get a plain-text version suitable for pasting into emails or messages. For recurring clients, use the same template and update the invoice number, dates, and line items for each new billing period.

Frequently Asked Questions
What should every professional invoice include?
A complete invoice must include: a unique invoice number, issue date, due date, your business name and contact details, client name and billing address, itemized list of services with descriptions and quantities, subtotal, any applicable taxes, total amount due, and payment instructions (bank transfer, PayPal, etc.). Missing any of these elements gives clients grounds to delay payment.
What do payment terms like Net 30 mean?
Net 30 means payment is due within 30 calendar days from the invoice date. Net 15 means 15 days; Net 60 means 60 days. 'Due on Receipt' means payment is due immediately upon receiving the invoice. For freelancers, Net 15 or Net 30 is standard. Shorter terms improve cash flow — use Net 30 for established clients and Net 15 for new relationships.
How should I number my invoices?
Use a consistent, sequential numbering system and never reuse invoice numbers. Common formats: INV-001 (sequential), 2026-03-001 (date-based), or CLIENT-001 (client-coded). Starting at INV-001 rather than INV-1 implies an established business. Sequential numbering makes record-keeping and tax preparation straightforward. Keep a simple spreadsheet tracking invoice number, client, amount, sent date, due date, and payment date.
Can I charge late fees on unpaid invoices?
Yes, but the late fee policy must be stated in your contract or on the invoice before it becomes overdue. Common rates are 1-1.5% per month (12-18% annually). Include your late fee policy on every invoice: 'Invoices unpaid after [due date] are subject to a 1.5% monthly late fee.' Some jurisdictions cap maximum late fee rates, so verify local regulations.
How long should I keep invoice records?
The IRS recommends keeping tax records including invoices for at least 3 years from the filing date. If you underreported income by more than 25%, the retention period extends to 6 years. Most accountants recommend 7 years for safety. Store digital copies in cloud backup (Google Drive, Dropbox) so they are accessible even if your device fails.
