A minimalist invoice has nothing to look at except the facts. This template uses hairline rules instead of boxes, small-caps labels, and a monospaced font for the numbers so every digit sits in the same column.
Free, fillable, US Letter, no email, no sign-up. The Avo app for iPhone makes invoices in its own layout and adds up the totals; this PDF is for the minimalist look.

The filled sample. Names, addresses and amounts are made up; the blank PDF you download has the same fields empty.
There is no colour on the page. The word INVOICE is set small at the top left, your name is the largest thing on the sheet, and the total due is separated from the lines by a single black rule. The white space is doing the work a header band usually does.
A copywriter billing a product launch: one fee per deliverable, a per-item line for product descriptions, one revision round.
The layout stays out of the way of your own letterhead. Print on good paper and it looks like it was typeset.
Renders cleanly in Gmail and Outlook previews and in the Files app on a phone. No colours to shift.
Your name and address at the top, the client block beneath, then four meta fields in a row: invoice number, issue date, due date, terms. Four item lines with quantity, rate and amount. Subtotal, tax and total due. A notes line for payment details.
The sample is a freelance copywriter invoicing a skincare brand for launch copy: landing page, twelve product descriptions, a four-email sequence and one extra revision round. No tax, no deposit, so the total is the sum of the lines.
| Description | Qty × rate | Amount |
|---|---|---|
| Landing page copy, two versions | 1 × $900.00 | $900.00 |
| Product descriptions | 12 × $45.00 | $540.00 |
| Launch email sequence, 4 emails | 1 × $720.00 | $720.00 |
| Revision round 2 | 1 × $180.00 | $180.00 |
| Subtotal | $2,340.00 | |
| Total due | $2,340.00 | |
Avo keeps your clients and your usual line items, so the next invoice is three taps. Your first three documents are free, full-quality PDF, no watermark. Premium from $59.99/year if you invoice often.

In a monospaced font every digit has the same width, so 1,250.00 and 7,800.00 line up without a table grid. That is what makes a minimalist layout readable at a glance.
There is room above your name, but the PDF has no image field. Open the file in Acrobat or a PDF editor and place the logo, or use the Word version of the standard template.
The modern and aesthetic designs on this site use the same field set with a colour accent. All are free.
Open the PDF in the Files app, tap a field and type; Files saves as you go. Then share the file by Mail or Messages. The Avo app does the same with saved clients and items.
