Time Tracking Software with Invoicing for Freelancers: Essential Features and Benefits

Learn which time tracking and invoicing features freelancers need to bill clients accurately, get paid faster, and understand their work.



Freelancers sell their time and skills. Whether you are a writer, designer, developer, consultant, marketer, or virtual assistant, the way you track your hours has a direct effect on how much you earn. If you forget to record an hour of work, that is money you will never get paid. If your invoices are unclear, clients may question them or pay late.

Many freelancers start by tracking time in a notebook or spreadsheet and creating invoices by hand. This works for a while, but as you take on more clients and projects, it quickly becomes messy and time-consuming.

That is why many freelancers use Time Tracking Software combined with invoicing tools. In this guide, we will explain why time tracking matters for freelancers, the essential features to look for, the benefits of connecting time tracking with invoicing, and tips to bill clients accurately and get paid on time.

Why Time Tracking Matters for Freelancers

For employees, time tracking is mostly about payroll. For freelancers, it is about much more.

You Get Paid for Every Hour

If you bill by the hour, every untracked minute is lost income. Small tasks like quick emails, short calls, and minor revisions add up over a month.

Clients Want Proof

Clients often want to see what they are paying for. Detailed time records show exactly how many hours went into each task.

Better Pricing

Even if you charge flat project fees, tracking time shows how long projects really take. This helps you set better prices for future work.

Understanding Your Business

Time records show which clients and projects are most profitable and which take more time than they are worth.

Avoiding Burnout

Tracking hours helps you see when you are working too much, so you can set healthy limits.

What Is Time Tracking Software With Invoicing?

Time tracking software records the time you spend working on tasks, projects, and clients. Invoicing tools turn that time into bills that you send to clients.

Some tools include both features in one app. Others focus on one job and work alongside a separate tool. For example, you might track your hours in one system, export a report, and use that report to create an invoice in your accounting or invoicing software.

Either way, the goal is the same: record time accurately and turn it into clear, professional invoices with as little manual work as possible.

Essential Time Tracking Features for Freelancers

Not every tool is a good fit for freelance work. Here are the most important time tracking features to look for.

Project and Client Tracking

You should be able to track time by client and by project. This keeps your records organized and makes billing much easier. Project time tracking lets you record hours against specific projects and create client-ready reports that show exactly where your time went.

Task-Level Tracking

Breaking projects into tasks, such as research, writing, design, revisions, and meetings, gives clients more detail and helps you see which tasks take the most time. Job time tracking helps you record time spent on individual tasks or jobs.

Easy Start and Stop

The faster you can start and stop tracking, the more likely you are to use the tool every day. Look for simple clock-in and clock-out buttons or timers.

Quick Switching Between Projects

Freelancers often jump between clients during the day. The tool should make it easy to switch from one project to another without losing time.

Manual Time Entry and Editing

Sometimes you forget to start a timer. A good tool lets you add or edit time entries after the fact, with notes explaining what you did.

Notes on Time Entries

Adding short notes to each time entry, such as "edited homepage copy" or "client call about logo," makes invoices clearer and easier for clients to approve.

Access From Any Device

Look for tools that work on your computer, phone, and tablet, so you can track time wherever you work.

Reports

Reports turn your time records into useful information. You should be able to see total hours by client, project, task, or date range, and export them for billing.

Essential Invoicing Features for Freelancers

Whether invoicing is built into your time tracker or handled by a separate tool, here are the features that matter most.

Creating Invoices From Tracked Time

The biggest time saver is turning tracked hours into invoices without retyping everything. Look for tools that can pull hours directly or import them from reports.

Different Rates for Different Clients

Many freelancers charge different hourly rates for different clients or types of work. Your invoicing tool should handle multiple rates.

Professional Invoice Templates

Clean, branded invoices make you look professional. Look for templates where you can add your logo, business details, and payment terms.

Online Payments

Clients pay faster when they can pay online by card or bank transfer. Many invoicing tools include payment links.

Payment Reminders

Automatic reminders for unpaid invoices save you from awkward follow-up emails.

Expense Tracking

If you pass costs such as software, travel, or stock images on to clients, your invoicing tool should let you add expenses to invoices.

Tax and Currency Settings

Depending on where you and your clients are located, you may need to add sales tax or VAT, or bill in different currencies.

Invoice Tracking

You should be able to see which invoices are sent, viewed, paid, or overdue.

Billable vs. Non-Billable Time

Not all freelance work can be billed to clients. Understanding the difference helps you price your services correctly.

Billable Time

This is time spent directly on client work that you can charge for, such as writing, designing, coding, or meetings with the client.

Non-Billable Time

This includes tasks like marketing your business, writing proposals, learning new skills, bookkeeping, and admin work. You do not bill clients for this time, but it still takes up your day.

Why It Matters

Tracking both types of time shows how many hours you actually spend working each week compared to how many hours you can bill. If you only bill 20 hours out of a 40-hour week, your hourly rate needs to cover the non-billable time too.

Getting Time Units Right

Many freelancers bill in decimal hours, such as 1.5 hours or 2.25 hours. Converting minutes to decimals by hand can lead to mistakes. For example, 1 hour and 45 minutes is 1.75 hours, not 1.45 hours.

A decimal hours calculator can help convert hours and minutes quickly and correctly before you add them to an invoice.

Some freelancers, especially in legal and consulting work, bill in set increments, such as six minutes or 15 minutes. If you use increments, explain this clearly in your contract so clients know how time is rounded.

Benefits of Connecting Time Tracking and Invoicing

Using time tracking and invoicing together brings many benefits for freelancers.

More Accurate Invoices

When invoices come directly from tracked time, there is less room for guessing or math errors.

Less Admin Work

Creating invoices from time records takes minutes instead of hours.

Faster Payment

Clear, detailed invoices with online payment options help clients pay sooner.

Fewer Disputes

When clients can see exactly what they are paying for, they are less likely to question invoices.

Better Financial Planning

Knowing how many hours you work and bill each month helps you plan income, savings, and taxes.

Stronger Client Relationships

Transparency builds trust. Clients who trust your billing are more likely to keep working with you and refer you to others.

How to Use Time Reports for Invoicing

If your time tracker and invoicing tool are separate, reports connect the two. Here is a simple process.

Track Time Every Day

Record your hours as you work, with clear notes for each entry.

Review at the End of the Billing Period

Check your entries for missing time, duplicate entries, or tasks assigned to the wrong client.

Run a Report by Client

Pull a report showing total hours by project and task for the billing period. Payroll and attendance reports can be exported in formats such as PDF and Excel, which makes them easy to attach to invoices or import into other tools.

Create the Invoice

Enter the hours and rates into your invoicing tool, or import the report if your tool supports it.

Attach Supporting Details

Some clients like to see a time report attached to the invoice. This adds transparency and can speed up approval.

Send and Follow Up

Send the invoice with clear payment terms and track when it is paid.

Tips for Billing Clients Accurately

Here are some simple habits that help freelancers bill fairly and get paid on time.

Agree on Terms Before You Start

Set your rate, billing schedule, payment terms, and how time will be tracked in a written contract.

Track Small Tasks Too

Quick emails, short calls, and small revisions add up. Track them even if they only take a few minutes.

Write Clear Descriptions

Avoid vague entries like "work." Instead, write specific notes like "drafted blog post outline."

Bill Regularly

Send invoices on a set schedule, such as weekly, every two weeks, or monthly. Regular billing keeps cash flowing and prevents large, surprising invoices.

Set Payment Terms

Common terms include payment due on receipt, in 15 days, or in 30 days. State this clearly on every invoice.

Consider Deposits for Large Projects

For big projects, ask for a deposit or milestone payments so you are not waiting until the end to get paid.

Keep Records

Save your time records and invoices. They are useful if a client questions a bill and for tax purposes.

Tax Considerations for Freelancers

Freelancers are usually responsible for their own taxes. Good records make tax time much easier.

Keep track of all income from invoices, along with business expenses. In many countries, freelancers need to set aside money for income taxes and may need to pay estimated taxes during the year. In the United States, self-employed workers generally pay self-employment tax in addition to income tax. Because tax rules vary by country and situation, it is a good idea to speak with a tax professional.

Choosing the Right Tool

With so many options available, here are some questions to help you choose the right Time Tracking Software for your freelance business.

Does It Track Time by Client and Project?

This is essential for accurate billing.

Is It Easy to Use Every Day?

The best tool is the one you will actually use. Try it for a few days before committing.

Does It Create or Export Invoices?

Choose a tool with built-in invoicing or one that exports reports you can easily use with your invoicing tool.

Does It Work on Your Devices?

Make sure it works on your computer and phone.

How Much Does It Cost?

Many freelancers start with free tools. For example, OpenTimeClock offers a free plan with project and job time tracking, and you can review all options on the pricing page. As your business grows, you may decide to upgrade or combine tools.

Can It Grow With You?

If you plan to hire subcontractors or build a small team, choose a tool that can handle multiple users.
