Hourly Invoice Template

Time is quite literally your inventory when you bill by the hour. Every hour you spend designing a website, writing a legal brief, consulting on a business strategy, or repairing a client system is an hour of billable time that needs to be accurately captured, clearly presented, and professionally invoiced. An hourly invoice template is specifically designed to help professionals who bill by the hour communicate their time expenditures to clients in a format that is transparent, easy to understand, and straightforward to approve.

The hourly invoice differs from a standard product-based invoice in one fundamental way: its central unit of measurement is time, not units of product. A product invoice lists quantities of items sold; an hourly invoice lists blocks of time worked, each associated with a specific rate and task. This makes the hourly invoice uniquely important as both a billing document and a record of work performed. When done well, it protects both you and your client by creating a clear, agreed-upon record of exactly what was accomplished and what was charged.

Eonebill's free hourly invoice template is built for professionals who track their time carefully and want an invoice format that reflects that rigor. It includes dedicated columns for date, task description, hours worked, hourly rate, and line totals. The template automatically calculates the subtotal, applies any applicable taxes, and presents a clean grand total. Whether you are a solo attorney billing at $350 per hour or a freelance social media manager charging $50 per hour, our template adapts to your rates and your workflow.

What Is an Hourly Invoice?

An hourly invoice is a billing document used by professionals who charge for their services by the hour rather than by project or product. It itemizes the time spent working on a client's matters, assigns an hourly rate to that time, and calculates the total amount owed. Hourly invoices are the standard billing method in many professional service industries, including law, accounting, consulting, architecture, engineering, freelance writing, graphic design, web development, and home repair services.

The hourly invoice format serves several critical functions in a professional services practice:

Transparency: By breaking down work into specific tasks and time blocks, an hourly invoice shows the client exactly what they are paying for. This transparency builds trust and reduces the likelihood of payment disputes.

Fair compensation: For the service provider, the hourly invoice ensures that all billable time—regardless of how small or unglamorous—is captured and compensated. A two-hour emergency repair call is as worth documenting and invoicing as a 40-hour website build.

Workload documentation: Hourly invoices serve as a record of work performed, which can be invaluable in the event of a dispute, an audit, or simply a conversation with a client about the scope of a project.

Cash flow management: For service businesses, the ability to invoice quickly based on logged hours is essential for maintaining healthy cash flow. An efficient hourly invoice template lets you convert your timesheet into a client-ready invoice in minutes.

The alternative to hourly billing is fixed-fee or project-based billing, where a single price is agreed upon in advance regardless of the time spent. Both approaches have advantages: hourly billing is fairer for open-ended or uncertain scopes of work, while fixed-fee billing provides certainty for the client. Many professionals use a hybrid approach—quoting a maximum or estimated fixed fee but billing hourly if the scope expands beyond the original agreement.

How to Create an Hourly Invoice

Creating a professional hourly invoice requires more detail than a simple product invoice. Here is how to do it properly using Eonebill's free template.

Step 1: Log Your Time Accurately

Before you can invoice, you need accurate time records. Log your time daily using a timesheet, a time-tracking app, or even a simple spreadsheet. Record the date, the client matter or project name, a brief description of the task, and the actual time spent. Do not round excessively in your client's favor at the risk of underbilling yourself, but do be consistent and reasonable in your rounding policies.

Step 2: Set Your Hourly Rate(s)

If you charge a single rate for all work, that rate should be clearly stated on your invoice. If you have tiered rates—for example, a senior consultant at $175/hr and a junior consultant at $95/hr—organize your time entries by rate category so the invoice correctly reflects who performed which work.

Step 3: Populate the Invoice Template

Using Eonebill's hourly invoice template, fill in your business details and the client's details at the top. In the time log section, enter each task as a separate line item with the date, description, hours, rate, and calculated total. The template will automatically compute each line's total (hours × rate) and the overall subtotal.

Step 4: Separate Multiple Rate Categories

If you have multiple consultants, contractors, or rate tiers working on the same client project, group the time entries by rate. For example, put all $150/hr entries together and all $75/hr entries together. This makes it easy for the client's accounts payable team to verify the billing and for their internal cost allocation systems.

Step 5: Review for Accuracy

Double-check that all hours are correctly entered, that rates match your agreement with the client, and that the math is accurate. Small errors in an hourly invoice—entering 1.5 hours when you meant 15 hours, for instance—can cause significant billing disputes.

Step 6: Add Tax and Payment Details

Apply the appropriate tax rate to the subtotal. Add your payment terms (Net 15, Net 30, etc.) and your preferred payment method (bank transfer, PayPal, etc.).

Step 7: Send Promptly

Invoice promptly for the work done. In professional services, billing promptly—when the work is still fresh in the client's mind—is one of the most effective ways to ensure timely payment.

Key Elements of an Hourly Invoice

An effective hourly invoice must contain all the standard invoice fields plus specific elements unique to time-based billing:

Your Business Name and Contact Information: Standard invoice requirement, establishing you as the issuing party.

Client Information: Standard invoice requirement. Include any client matter or project reference number if applicable.

Invoice Number and Date: Standard requirement. Use a clear numbering system to track your invoices.

Time Log Entries: Each entry should include: the date the work was performed, a description of the specific task completed, the number of hours worked (in decimal or fraction format), the hourly rate applied, and the line total.

Rate Column: Clearly state the hourly rate for each category of work. If rates vary by consultant or by task type, label them accordingly.

Subtotal: Sum of all time-based line totals before taxes.

Tax Calculation: Apply the correct tax rate to the subtotal.

Grand Total: The final amount due.

Notes Section: Use this to reference any relevant agreements, rate change notices, or additional context about the work performed.
