Simple Invoice Template

Sometimes you do not need a 20-field invoice with multiple rate categories, tax rate breakdowns by jurisdiction, and a 10-item line item table. Sometimes you just need to send a clean, honest, straightforward request for payment that anyone can understand at a glance. A simple invoice template is designed for exactly these moments—when the scope of work is self-evident, the amount is fair, and what you need is the fastest, cleanest way to say "here is what I did, here is what I charge, here is how to pay me."

Eonebill's free simple invoice template embraces the philosophy that less is more. It strips away everything that is not essential, leaving only the information your client needs to understand what they owe and pay it. Clean layout, clear typography, no visual clutter. The result is an invoice that gets opened, understood, and paid—without the client having to wade through a document that is more complex than it needs to be.

What Is a Simple Invoice?

A simple invoice is the most stripped-back version of a billing document. It contains only the information that is absolutely necessary to bill for and record a transaction: who is billing whom, what for, how much, and how to pay. It deliberately excludes optional or supplementary information that may be useful in some contexts but would be unnecessary noise in others.

A simple invoice is appropriate when:

• The transaction is straightforward: A single product or a clearly defined, well-understood service. No need to itemize a one-page website or a single consulting session.
• The amount is modest: For small transactions, the time spent creating a detailed multi-line invoice may exceed the value of doing so.
• The relationship is ongoing: When you have a monthly retainer or ongoing relationship with a client, both parties already know the scope and terms—no need to restate everything in detail each month.
• Speed matters: When you need to invoice quickly and do not want to spend time populating unnecessary fields.

The simple invoice is not a lesser document—it is a focused one. It knows what it needs to communicate and does so without preamble. In the right situations, a simple invoice is actually more effective than a complex one because it respects the client's time and removes every obstacle between them and payment.

How to Create a Simple Invoice

Step 1: Identify the Essential Information

Before you start filling in the template, ask yourself: what does my client absolutely need to see to understand this invoice and process payment? Usually the answer is: your name, their name, what you did, the total, and how to pay. That is it.

Step 2: Write a Clear Description

Even in a simple invoice, the description matters. "Consulting Services, April 2026" is better than "April Services." "Logo Design Package — Final Delivery" is better than "Design Work." The description should answer the client's implicit question: "What am I paying for?"

Step 3: State the Total Prominently

The total amount due should be the most prominent figure on the invoice. Do not bury it. Use a larger font size, bold weight, and clear positioning so the client sees it immediately.

Step 4: Provide One Clear Payment Method

A simple invoice should have one primary payment method stated clearly: your bank account details for a wire transfer, or a link to your payment portal. Do not overwhelm with five different payment options—pick the best one and make it easy.

Step 5: State the Due Date

Even in a simple invoice, the due date matters. Write it out in full: "Payment due by May 14, 2026." This is clearer than "Net 30" for many clients who may not know what "Net 30" means or who may have to look it up.

Step 6: Keep It Short

A simple invoice should fit on one page. If you find yourself adding extensive notes, multiple items, or detailed terms, consider whether a more detailed invoice format would be more appropriate.

Key Elements of a Simple Invoice

Your Name or Business Name: Who is sending the invoice.

Client Name: Who is receiving the invoice.

Invoice Number: A simple sequential identifier (e.g., "INV-001").

Date and Due Date: When it was issued and when payment is expected.

Description: A clear, one-line or brief description of what was delivered.

Total Amount: The single most important number—make it prominent.

Payment Instructions: One clear method for how to pay.
