Question 1

What should be included on a professional invoice?

Accepted Answer

A professional invoice should include your business name and contact information, the client's name and address, a unique invoice number, the invoice date and due date, an itemized list of products or services with quantities and rates, subtotal, any applicable taxes and discounts, the total amount due, accepted payment methods, and payment terms. Including all of these details reduces confusion and helps ensure you get paid on time.

Question 2

How do I calculate sales tax on an invoice?

Accepted Answer

To calculate sales tax, multiply the taxable subtotal by your local tax rate. For example, if your subtotal is $1,000 and your sales tax rate is 8.25%, the tax amount is $1,000 x 0.0825 = $82.50. Different states, counties, and cities may have different tax rates, and some products or services may be tax-exempt. Our invoice generator lets you enter your tax rate and automatically calculates the amount for you.

Question 3

What is the difference between an invoice and a receipt?

Accepted Answer

An invoice is a request for payment sent before or at the time of delivery, while a receipt is a confirmation of payment already made. Invoices include payment terms and due dates, while receipts confirm the transaction amount and date of payment. In short: an invoice says "please pay this amount," and a receipt says "thank you, payment received." Both are important financial documents for bookkeeping.

Question 4

Is this invoice generator really free?

Accepted Answer

Yes, the PrestoKit invoice generator is 100% free with no hidden fees, no watermarks, and no account required. Everything runs directly in your browser, which means your data never touches our servers. You can create and download as many invoices as you need at no cost.

Question 5

Can I customize the invoice with my logo?

Accepted Answer

Yes! The PrestoKit invoice generator supports logo upload directly in the tool. Simply click the logo upload area in the Your Business section, select a JPG or PNG file, and your logo will appear in the invoice preview and PDF download immediately. No third-party tools needed.

Question 6

What file format does the invoice download as?

Accepted Answer

When you click "Download PDF," the invoice is rendered and exported as a high-quality PDF using html2pdf.js, entirely in your browser. The PDF maintains all formatting, colors, and your uploaded logo. This is the most universally accepted format for invoices because PDFs maintain their formatting across all devices and operating systems.

Question 7

How do I send an invoice to a client?

Accepted Answer

After downloading your invoice as a PDF, you can send it via email as an attachment with a professional message summarizing the amount due and payment deadline. You can also share it through cloud storage links (Google Drive, Dropbox), messaging apps, or even print and mail a physical copy. Most clients prefer receiving invoices via email for quick processing.

Question 8

What payment terms should I include on my invoice?

Accepted Answer

Common payment terms include Net 30 (payment due within 30 days), Net 15 (within 15 days), and Due on Receipt (immediate payment). For new clients, shorter payment terms reduce risk. You might also consider offering a small early-payment discount (e.g., 2% off if paid within 10 days) to encourage faster payment. Always clearly state your accepted payment methods, such as bank transfer, credit card, or PayPal.
