Billing and invoicing can be a particularly stressful step in completing projects, especially if when it comes to the relationship between the business and the client. We all want to provide a fair estimate and straightforward service that builds trust.

Luckily for us, that’s where time and billing software comes into play. We can track our billable hours and provide clients with clean-cut reports.

Billing and time software-cover

This article briefly explains how billing works and presents key features to look out for, as well as some of the best software regarding both time tracking and billing.

What are time and billing?

Whether you are a freelancer, an owner of a small business or the CEO of a growing startup, we all want to have an insight into our work time. For our business to survive and thrive, we should always know the amount of time spent at work, how much of it can be billed and ultimately, it should be presented to our clients.

There are two types of billing:

  1. Flat rate – employed by companies/businesses who charge a fixed rate per project, regardless of how much time was spent on completing it;
  2. Hourly rate – employed by companies and individuals who charge for the time spent on each new project.

Those who tend to bill per hour are usually designers, freelance writers, programmers, accountants, attorneys, etc.

ℹ️ If you’re still trying to find your footing with billing and invoicing, we’ve written a comprehensive guide that addresses all of the pitfalls and solutions, as well as commonly asked questions.

And if you, like them, use hourly billing, then you will need time tracking and billing software. But how will you know what to choose?

The following section should help you identify what kind of time and software would work best for your specific needs.

What key features does the software need to have?

Once you start looking for a time and billing app or program, you’re bound to encounter a wall: which one will work best for you?

While time tracking will vary across different industries, there are some key boxes that need to be checked to get the best value for your money. In the following section, we’d like to give you some more info. Instead of just listing a dozen apps and letting you decide on trial and error, we want to help you know just by reading the app description if it is the right one for you.

A good time and billing software should have these key features:

  1. Task assignment (also project/client assignment)
  2. Time tracking – billable and non-billable hours
  3. Billing reports
  4. Invoice creation
  5. A mobile version
  6. Affordable pricing

Now, let’s see what makes each of these features so important.

1. Task assignment

The software you choose should allow you to divide your project into tasks, schedule them, and track time for each one.

Since not everything you do will be billable time, you want to be able to differentiate between work that you can charge, and the one you can’t (unrelated to the project or client – answering emails, creating invoices, etc.)

Secondly, if you’re managing a team, you’ll want the ability to set different rates for each team member, assign them tasks and projects.

2. Time tracking

Once you’ve assigned the tasks, the software should enable you to track the hours spent on the project. If it has an option to mark the task as being billable or non-billable, all the better. It will only help in creating final reports.

What’s more, you’ll need the option to track these hours across multiple projects or clients. After all, very few of us have a single project at a time, and it’s not easy to keep track of all of them simultaneously.

3. Billing reports

The sole purpose of tracking time and billing is to be able to fairly charge for your time. Billing reports help you create accurate invoices and be completely transparent with your clients.

Any good software will have the option of creating a billing report at the end of the project. With billable and non-billable times displayed through a graph or a spreadsheet, it’ll be much easier to create an invoice and get additional insight into your workflow.

Additionally, on an off chance that a client wants to avoid paying you in full or has an issue with the charge, you can use it to contest their arguments. Think of billing reports as a safety net in extreme cases.

4. Invoice creation

After creating a billing report, you’ll have a much easier time making an invoice.

Not every piece of software will have invoicing included in it, and many of these software companies decide on partnering up with a service like PayPal, Payoneer, or Venmo.

ℹ️ If you’re having trouble finding good invoicing apps, we’ve done a top list of free apps that can help you.

5. A stable mobile version

You and your team (if you work with one) will get the most out of the software if it offers a mobile version as well. Apps usually have a much simpler interface and are more accessible, due to the limitations of smartphones.

For example, in Clockify’s app, a person can choose their task and start the time tracker by tapping a button on the screen. Once they’re done, they simply tap it again to stop tracking. Easy, right? And it’s precisely why so many business owners, as well as freelancers, prefer to have a mobile app to accompany the desktop software.

6. It needs to be priced appropriately

It’s only natural that you’ll want the most bang for your buck.

When it comes to choosing the best software for your business, you’ll want to find those that offer at least free trials.

These six features can make or break a time and billing software, and now that you know a little more, let’s see how the best apps fare against them.
