InvoiceGen processes everything in your browser. Your invoice data is stored locally on your device and is never sent to our servers. No tracking, no data selling, no hidden analytics on your business information. You stay in complete control.
Step-by-Step Guide
Creating a professional invoice with InvoiceGen takes less than two minutes. Follow these six simple steps to generate a polished PDF invoice ready to send to your clients.
Start by selecting the type of document you need. InvoiceGen supports invoices, credit notes, quotes and estimates, purchase orders, and receipts. Each type comes with tailored labels so your document looks correct from the start. Whether you are billing a client for completed work or providing an upfront estimate, picking the right document type ensures clarity and professionalism.
Enter your business name, address, email, and phone number in the “Bill From” section. You can also upload your company logo for a branded look. These details tell your client exactly who is billing them and how to reach you if they have questions. Keeping this information consistent across every invoice strengthens your brand identity.
Fill in your client’s name, company, and address in the “Bill To” section. Accurate client details are essential for proper record-keeping and ensure the invoice reaches the right person. If your client has a purchase order number or reference code, you can include that in the custom fields for easy matching on their end.
Add each product or service as a line item with a description, quantity, and unit rate. InvoiceGen calculates the line totals automatically. You can add as many items as you need. Itemizing your work helps clients understand exactly what they are paying for and reduces disputes down the line.
Open the settings panel to toggle tax, discount, and shipping fields. Set tax as a percentage or flat amount depending on your jurisdiction. Add discounts for loyal clients or promotional pricing, and include shipping costs if applicable. All amounts are computed automatically and reflected in the final total on your PDF.
Click the “Download” button to generate a professional, print-ready PDF. The document includes your logo, all line items, calculated totals, and payment terms. You can email it directly to your client, print a hard copy, or save it to your records. The entire process takes under two minutes and costs nothing.
Essential Elements
A well-structured invoice gets you paid faster and keeps your books clean. Here are the twelve components every professional invoice should contain.
A unique sequential identifier that helps both you and your client track and reference the transaction. Essential for accounting and tax filing.
The date the invoice is issued. This establishes the billing timeline and is the starting point for payment term calculations.
The deadline by which payment should be received. Clearly stating the due date reduces late payments and sets expectations upfront.
Your company name, address, email, and phone number. This identifies you as the seller and gives the client a way to contact you.
The buyer's name, company, and address. Accurate client details ensure the invoice reaches the right department and person.
An itemized list of products or services, each with a description, quantity, and unit price. Itemization provides transparency.
The sum of all line items before tax, discounts, or shipping. It gives the client a clear view of the base cost of your work.
Sales tax, VAT, or GST applied to the subtotal. Showing the tax separately is a legal requirement in most jurisdictions.
The final amount the client owes after tax, discounts, and any additional charges. This is the single most important number on your invoice.
Conditions like Net 30, Due on Receipt, or early payment discounts. Clear terms reduce confusion and encourage timely payment.
Additional instructions such as bank transfer details, late fee policies, or a thank-you message. A personal touch can strengthen client relationships.
Your brand logo adds professionalism and makes the invoice instantly recognizable. InvoiceGen lets you upload PNG, JPG, or SVG logos.
Payment Terms
Payment terms tell your client when and how to pay. Using standard terms avoids misunderstandings and helps you maintain healthy cash flow. Here are the most widely used payment terms in freelancing and small business invoicing.
| Term | Meaning |
|---|---|
| Net 30 | Payment is due within 30 calendar days of the invoice date. This is the most common payment term used in business-to-business transactions worldwide. |
| Net 15 | Payment is due within 15 days. Shorter terms like Net 15 are popular among freelancers and small businesses that need faster cash flow. |
| Net 60 | Payment is due within 60 days. Typically used for large orders or enterprise clients where longer processing times are standard. |
| Due on Receipt | Payment is expected immediately upon receiving the invoice. Best for one-time projects or when you want to minimize payment delays. |
| 2/10 Net 30 | The client receives a 2% discount if they pay within 10 days; otherwise, the full amount is due in 30 days. This incentivizes early payment. |
| EOM | End of Month — payment is due by the last day of the month in which the invoice is received. Common in industries with monthly billing cycles. |
| COD | Cash on Delivery — payment is collected when the goods or services are delivered. Frequently used in retail, logistics, and field service businesses. |
Pro Tips
Getting paid on time starts with a great invoice. These eight best practices will help you look professional, reduce disputes, and keep your cash flow steady.
Use a consistent numbering system like INV-001, INV-002, and so on. Sequential numbers make it easy to track outstanding payments and simplify your year-end bookkeeping.
Always include a specific due date rather than vague terms like "due soon." A concrete deadline such as "Due by May 15, 2026" eliminates ambiguity and sets professional expectations.
Break your work into individual line items with descriptions, quantities, and rates. Detailed invoices are less likely to be questioned and help your client understand the value you delivered.
List accepted payment options — bank transfer, PayPal, credit card, or check — along with the relevant account details. The easier you make it to pay, the faster you get paid.
Send a polite reminder within a day or two of the due date. A short, friendly email referencing the invoice number is often all it takes to nudge a late payment.
Maintain a local or cloud backup of all invoices you send. You will need them for tax returns, financial reporting, and resolving any future disputes with clients.
A clean, branded invoice template with your logo and consistent formatting signals credibility. InvoiceGen provides a professional layout out of the box at no cost.
Issue your invoice as soon as the work is completed or the product is delivered. Delays in invoicing lead to delays in payment and can signal disorganization to your clients.
Support
Everything you need to know about creating invoices with InvoiceGen.
An invoice is a commercial document issued by a seller to a buyer, detailing the products or services provided, their quantities, and the agreed-upon prices. It serves as a formal request for payment and is essential for business record-keeping and accounting.
With InvoiceGen, simply fill in your business details, add your client information, list your items or services with quantities and rates, and click Download. No sign-up or credit card required. Your invoice is generated as a professional PDF instantly.
A professional invoice should include: your business name and contact details, the client's name and address, a unique invoice number, the invoice date and payment due date, an itemized list of products or services with quantities and prices, the total amount due, payment terms, and any applicable tax information.
An invoice is sent before payment as a request for payment, while a receipt is issued after payment as proof of transaction. Invoices detail what is owed, whereas receipts confirm what has been paid. InvoiceGen lets you create both document types.
No. InvoiceGen is completely free with no sign-up required. You can create, customize, and download professional PDF invoices immediately. Your data stays in your browser for privacy.
Yes. InvoiceGen supports over 160 currencies from around the world, including USD, EUR, GBP, JPY, AUD, CAD, and many more. Simply select your preferred currency from the settings panel.
In the invoice settings sidebar, toggle on Tax, Discount, or Shipping. You can set tax and discount as either a percentage or a flat amount. These are automatically calculated and displayed on your invoice and PDF.
InvoiceGen supports five document types: Invoice, Credit Note, Quote/Estimate, Purchase Order, and Receipt. Each type comes with appropriate default labels that you can customize to match your needs.
Yes. InvoiceGen processes everything in your browser. Your invoice data is stored locally on your device and is never shared with third parties. You can also save to our secure cloud backend for cross-device access.
Yes. Click the logo upload area in the invoice form to upload your company logo. It will appear on your invoice and in the downloaded PDF. Supported formats include PNG, JPG, and SVG.
After creating your invoice with InvoiceGen, download the PDF and attach it to an email to your client. Include a brief message stating the invoice number, amount due, and payment deadline. Many freelancers also include their preferred payment method directly in the email body for convenience.
A credit note is a document issued to reduce the amount a client owes, typically after an overcharge, returned goods, or a billing error. It references the original invoice and specifies the credited amount. You can create credit notes directly in InvoiceGen by selecting "Credit Note" as the document type.
A purchase order (PO) is a document sent by a buyer to a seller to authorize a purchase. It outlines the items, quantities, and agreed prices before the transaction takes place. InvoiceGen lets you create professional purchase orders that you can send to your suppliers or vendors.
A quote (or estimate) is sent before work begins to give the client an idea of expected costs, while an invoice is sent after work is completed to request payment. Quotes are not legally binding, but invoices represent a formal payment obligation. InvoiceGen supports both document types.
Invoice numbering should be sequential and unique to help with organization and tax compliance. Common formats include simple numbers (001, 002, 003), date-based prefixes (2026-001), or client-based codes (ACME-001). InvoiceGen lets you set any custom invoice number format you prefer.
InvoiceGen is designed for on-demand invoice creation rather than automated recurring billing. However, you can save your invoice data locally and quickly duplicate it for repeat clients. Simply load your saved data, update the date and invoice number, and download a new PDF in seconds.
The most common payment terms include Net 30 (payment due within 30 days), Net 15, Due on Receipt (immediate payment), and 2/10 Net 30 (2% discount if paid within 10 days, otherwise due in 30). The right choice depends on your industry, cash flow needs, and client relationships.
Send a friendly reminder one to two days after the due date, followed by a firmer notice at 7 days and 14 days overdue. After 30 days, consider a phone call or a formal collections notice. Keeping your invoices professional and clearly dated with InvoiceGen makes follow-ups easier to manage.
Sales tax requirements vary by jurisdiction, business type, and the goods or services you sell. In most regions, businesses must collect and remit sales tax if they exceed a certain revenue threshold. Consult your local tax authority or an accountant, and use InvoiceGen's tax toggle to add the correct rate to your invoices.
Yes. InvoiceGen is fully responsive and works on smartphones, tablets, and desktops. You can create, edit, and download PDF invoices from any mobile browser without installing an app. The interface adapts to your screen size for a seamless experience on any device.
