Frequently asked questions

What should an invoice include?

A professional invoice should include: your business name and contact details, the client's name and address, a unique invoice number, issue date and due date, an itemised list of services or products with quantities and rates, subtotal, any taxes, and the total amount due. Payment terms (e.g. Net 30) and bank or payment details in the notes field are also strongly recommended to avoid payment delays.

What are standard payment terms for agencies?

Most agencies use Net 15 or Net 30 payment terms - meaning payment is due 15 or 30 days after the invoice date. Project-based agencies often require a 50% deposit upfront with the remainder due on delivery. Retainer clients are typically billed monthly on Net 7 or Net 15 terms. Shorter payment terms (Net 15 vs Net 30) measurably improve agency cash flow.

How do I calculate the total on an invoice?

Multiply each line item's quantity (or hours) by its rate to get the subtotal per item. Sum all line item subtotals to get the invoice subtotal. Add any applicable taxes (e.g. VAT or sales tax) to reach the total amount due. Example: 10 hours × $150/hr + 5 hours × $95/hr = $1,500 + $475 = $1,975 total before tax.

What invoice number format should I use?

A common format is a prefix plus sequential number - for example INV-001, INV-002. Including the year makes filing easier: INV-2026-001. The most important thing is consistency. Each invoice must have a unique number for accounting and audit purposes. Never reuse invoice numbers, even for cancelled invoices.

What is Net 30 and when should I use it?

Net 30 means payment is due within 30 calendar days of the invoice date. It's the most commonly used payment term in B2B agency work. Use Net 30 for established clients with a good payment history. For new clients or large projects, Net 15 or a 50% upfront deposit reduces your exposure. Net 30 is standard; shorter terms are better for cash flow.

What is the difference between an invoice and a receipt?

An invoice is a request for payment - you send it before the client pays. A receipt is a confirmation of payment - you issue it after the client pays. Invoices include payment terms, due dates, and line item details. Receipts confirm what was paid and when. Most accounting software generates both. For client work, always issue an invoice first.

How do I invoice a client for the first time?

For a first-time client: agree on scope and rate before starting work, clarify payment terms upfront (Net 15 or 30), then send the invoice on completion (or per your agreed schedule). Include your full business details, the client's legal name, an itemised breakdown of work, and clear payment instructions in the notes field. A professional first invoice builds client trust.

Can I use this invoice generator for free?

Yes. This invoice generator is completely free with no sign-up required. Fill in your details, add line items, and download a professionally formatted PDF. No account, no watermark, no limit on the number of invoices you create.

Is this invoice generator suitable for freelancers and agencies?

Yes - it works for both. Freelancers can invoice clients directly with their name and address. Agencies can use their business name, add multiple service line items, and toggle between hours-based and quantity-based billing per line. The payment terms field covers Net 7 through Net 60 and custom due dates.

Can I create a VAT invoice with this tool?

The invoice generator supports adding tax to your line items and including tax details in the notes field. For VAT-compliant invoices in the UK and EU, add your VAT registration number and the applicable VAT rate in the notes field. The PDF will include this information alongside your itemised charges.

Does the invoice PDF work on mobile?

The invoice generator works on any modern browser including mobile. The PDF is generated client-side using your browser - no data ever leaves your device and nothing is stored on our servers. Everything stays private.
