Frequently asked questions
Is the fillable invoice template free to use?+
Yes. You can open the template, fill in every field and preview your invoice for free, with no account. Filling out the form and getting a clean, watermark-free PDF is the whole point — you only ever pay if you choose a paid plan to remove limits, never to access the basic template.
What information goes on an invoice?+
A standard invoice includes your business name and address (seller), your client's details (buyer), a unique invoice number, the issue date, an itemized list of goods or services with quantity and unit price, the subtotal, any applicable tax, the total amount due, and your payment terms. There's no statutory layout — these are the fields clients and accountants expect.
Do I have to file or submit my invoice anywhere official?+
No. A commercial invoice is not filed with a tax office or government agency — you send it directly to your client to request payment. (For international shipments a copy may travel with customs paperwork.) iFillPDF helps you fill and download the invoice; it never submits or sends it to any authority on your behalf.
How do I send the invoice to my client?+
Once you've filled it out and downloaded the PDF, email it as an attachment, share it via a link, send it by text message, or print and mail a paper copy. The method usually comes down to your client's preference; emailing a PDF is the most common.
Does a fillable invoice have legal value?+
An invoice is a commercial billing document, not a contract — but a complete, accurate invoice with a number, date, itemized amounts and tax is a valid record for accounting, payment and tax purposes. Filling it out online or signing it electronically does not reduce its validity. For specific tax obligations in your country, check with a qualified accountant.
Can I add my logo and signature?+
Yes. You can place your business details and an e-signature directly on the invoice before downloading. Adding a signature makes the document look finished and professional, and you can save your filled invoice as a reusable starting point for the next one.
What are the most common invoicing mistakes to avoid?+
The usual culprits are an incorrect or missing total, a duplicate or missing invoice number, wrong client details, and forgetting to state payment terms or a due date. Double-check the math on subtotal, tax and total, and confirm the buyer's information before you send — small errors are the main cause of delayed payments.
Can I fill out the invoice on my phone?+
Yes. iFillPDF runs in your browser on desktop, tablet and mobile, so you can complete and download an invoice from anywhere — handy when you need to bill a client right after finishing a job.
