How to Use
- 1Fill in your business details in the 'From' section: your business name (or personal name for sole proprietors), full address, and contact information. This appears at the top of the invoice as the sender — make sure it matches the name on your business bank account to avoid payment confusion.
- 2Complete the 'Bill To' section with your client's name, company, and address. Accurate client details are important for the client's own bookkeeping and tax records, especially for B2B invoices where they may need to claim the expense as a tax deduction.
- 3Set the invoice number, issue date, and due date. Use a consistent numbering format (e.g., INV-2026-001) that increments sequentially — this is a legal requirement in many jurisdictions and helps both you and your client track payments. Common payment terms are Net 15, Net 30, or Net 60 days from the issue date.
- 4Add line items by clicking 'Add Item' for each product or service. Enter a clear description (e.g., 'Website redesign — homepage and 4 inner pages'), quantity (hours, units, or quantity of 1 for flat-rate services), and unit price. Each row automatically calculates its subtotal (quantity x unit price).
- 5Configure the tax rate if applicable. Enter your VAT, GST, sales tax, or other applicable tax percentage — the tool calculates the tax amount and adds it to the subtotal automatically. Apply a discount percentage if you are offering promotional or early-payment pricing.
- 6Add payment instructions, bank details, or terms in the notes field (e.g., 'Payment via bank transfer to Account #12345678, Sort Code 12-34-56. Late payments subject to 1.5% monthly interest.'). This is where clients look for how to pay you.
- 7Click 'Download PDF' to export your invoice. This opens your browser's print dialog — select 'Save as PDF' as the destination. The exported PDF has no watermarks, no ToolCenterLab branding, and looks like a professional invoice you created with dedicated accounting software.
About Invoice Generator
The Invoice Generator lets freelancers, consultants, contractors, and small business owners create professional invoices directly in the browser — no accounting software subscription, no account creation, and no recurring fees. Fill in your business details and client information, add line items with descriptions, quantities, and unit prices, and the tool automatically calculates subtotals, applies your tax rate, and presents the total amount due in a clean, print-ready layout.
Invoicing is a legal and financial requirement for any business, regardless of size. In most jurisdictions, invoices must include specific information: the seller's name and address, the buyer's name and address, a unique sequential invoice number, the date of issue, a description of goods or services, the amount due, and applicable tax details. This tool includes all of these standard fields, helping you create invoices that meet the documentation requirements for tax filing, audit trails, and client bookkeeping in countries following GAAP (Generally Accepted Accounting Principles) or IFRS (International Financial Reporting Standards) guidelines.
The line item system supports unlimited rows, each with its own description, quantity, and unit price. Subtotals are calculated automatically (quantity x unit price), and the tool sums all line items before applying the tax rate. This structure works for hourly billing (e.g., 40 hours x $75/hr for consulting), per-unit billing (e.g., 500 units x $2.50 for products), and flat-rate billing (e.g., 1 x $3,000 for a website redesign project). The discount field applies a percentage reduction before tax, which is the standard calculation order for most tax jurisdictions.
For freelancers and independent contractors, consistent invoicing is critical for cash flow management and tax compliance. The IRS (in the United States), HMRC (in the United Kingdom), and equivalent tax authorities worldwide require businesses to maintain records of all invoices issued and received. Sequential invoice numbering (INV-001, INV-002, etc.) is a legal requirement in many EU countries under VAT regulations and is considered best practice everywhere. This tool lets you set any numbering format, but maintaining a consistent, gap-free sequence is strongly recommended.
The PDF export works through the browser's native print-to-PDF functionality, which means the output quality matches any natively generated PDF. The exported document contains no watermarks, no ToolCenterLab branding, and no advertisements — it looks indistinguishable from an invoice created in QuickBooks, FreshBooks, or Wave. The print stylesheet is optimized for A4 and US Letter paper sizes, with proper margins and page break handling for invoices with many line items.
All invoice data stays entirely in your browser. No information is transmitted to any server, stored in cookies, or logged. This is particularly important for business-sensitive data like client details, pricing structures, and financial terms. When you close the tab, the data is gone — if you need to reuse invoice templates, save the PDF and consider keeping a spreadsheet of your invoice records for tax season. For businesses that need recurring invoices, automatic payment tracking, or integration with bank accounts, dedicated accounting software like QuickBooks, Xero, or Wave is the appropriate next step.
Frequently Asked Questions
Is the invoice generator really free?
Yes, completely free with no account required. There are no usage limits, no watermarks on exported PDFs, no ToolCenterLab branding on your invoices, and no hidden fees. The tool is designed for freelancers and small businesses who need to create occasional invoices without committing to monthly accounting software subscriptions that typically cost $15-50/month.
How do I save the invoice as a PDF?
Click 'Download PDF' which opens your browser's native print dialog. Select 'Save as PDF' (Chrome, Edge) or 'PDF' in the destination dropdown (Safari, Firefox) to save the file to your device. The browser's built-in PDF engine produces high-quality, universally compatible PDF files that can be emailed, printed, or uploaded to any accounting system. No third-party PDF library or browser extension is needed.
Can I add multiple line items to an invoice?
Yes. Click 'Add Item' to insert as many line items as your invoice requires — there is no limit. Each row has its own description, quantity, and unit price fields, and the subtotal (quantity x unit price) is calculated automatically. This supports hourly billing (e.g., 40 hours at $75/hr), per-unit billing (e.g., 500 items at $2.50 each), and flat-rate billing (e.g., 1 x $3,000 for a project).
Does it support different tax rates like VAT, GST, or sales tax?
Yes. Enter any tax percentage in the tax rate field — the tool calculates the tax amount based on the subtotal (after any discount) and adds it to produce the total. This works for VAT (common in EU countries at rates like 20-25%), GST (10% in Australia, 5% in Canada), US state sales tax (typically 4-10%), or any other percentage-based tax. The tax is applied after discounts, which is the standard calculation order in most jurisdictions.
What invoice number format should I use?
Use a consistent, sequential format that makes sense for your business. Common patterns include INV-001, INV-2026-001 (year-prefixed), or project-based formats like PROJ-ACME-001. In many EU countries, VAT regulations legally require sequential invoice numbering with no gaps. Even where not legally required, sequential numbering is considered best practice for bookkeeping, audit trails, and tax filing. The tool accepts any alphanumeric format you choose.
Can I add my business logo to the invoice?
The current template does not include a logo upload field. For branded invoices, you can add your logo after export by opening the PDF in a PDF editor like Adobe Acrobat, Preview (macOS), or the free online tool Smallpdf. Alternatively, you can print the invoice and add your logo header using a word processor. If branded invoices are a frequent need, dedicated invoicing software like FreshBooks or Wave includes logo upload as a standard feature.
Is my invoice data stored or sent to a server?
No. The entire invoice — including your business details, client information, line items, and pricing — is generated and rendered entirely in your browser. No data is transmitted over the network, stored in cookies, saved to local storage, or logged in any way. When you close the browser tab, the data is gone. This makes the tool safe for sensitive financial and client data, but also means you should save the PDF before closing the page.
Can I create recurring invoices or save templates?
This tool is designed for one-off invoice creation without persistence. It does not save templates or support recurring invoices — each session starts fresh. For businesses that need recurring invoices, saved client profiles, automatic payment reminders, or integration with bank accounts and payment processors, dedicated accounting software like QuickBooks ($30/month), Xero ($15/month), or Wave (free) provides those features. This tool fills the gap for freelancers who need an occasional professional invoice without a subscription commitment.
What payment terms should I include on my invoice?
Common payment terms include Net 15 (payment due within 15 days), Net 30 (30 days), and Net 60 (60 days). For freelancers and small projects, Net 15 or 'Due upon receipt' helps maintain cash flow. Include your preferred payment method in the notes field — bank transfer details (account number, sort code or routing number), PayPal email, or payment link. Some freelancers add a late payment clause (e.g., '1.5% monthly interest on overdue balances') to incentivize timely payment, though enforceability varies by jurisdiction.
