How can you account for hours?

Time registration is essential for insight into your time spent and project progress. Below, we'll discuss three ways you can efficiently account for your hours.

1. Time accounting in Excel

Excel is a popular choice for time management. It offers an easy way to keep track of your hours without the need for additional software.

Why should you opt for time management in Excel?

  • Easy entry method, anyone can work with it
  • No additional software required
  • You can completely customize columns, formulas, and colors to suit your needs

💡 Tip: Create templates in Excel for consistency and overview. TimeChimp offers free Excel templates to keep track of for hours.

2. Time registration software

With time registration software, you can not only track hours, but also record them based on specific projects, activities and customers. This provides a detailed overview of your time spent by project or customer, allowing you to use your time more effectively.

Why should you choose time registration software?

  • Record time on specific projects, activities, and customers
  • Generate invoices based on registered hours
  • Keep an overview of multiple projects and teams

3. Automatic time recording

Tired of keeping track of your hours manually? Automatic time registration tools are the solution. These tools automatically track how much time you spend on different tasks or projects without you having to think about them yourself.

Why should you opt for automatic time registration?

  • No forgotten registrations, always a complete overview
  • This allows you to easily switch between projects and tasks.
  • Ideal for multi-taskers and professionals who work with multiple deadlines.

Example of time accounting

To keep track of time sheets properly, it can help to follow a clear structure. Below is a simple example of what an hour statement can look like:

  • Date: The day the work was done.
  • Customer: The customer for whom the work was carried out
  • Projekt: The specific project that has been worked on.
  • Task: The task or activity that was performed.
  • Hours worked: The number of hours spent on this task.
  • Remarks: Optional field to note additional information or details.

Flawless time accounting: this is how you approach this successfully

Good time management is about efficiency, transparency and smart planning. With the right tools, you get better insight into time spent, projects, and customer relationships, while streamlining your administration.

1. Use specialized tools

Specialist time registration tools are much more efficient than traditional methods such as Excel. They have useful features such as:

  • Automatic timers
  • Reports
  • Integrations with other software

This prevents manual errors and complicated formulas. You can detailed reports generate that provide insight into the time spent by team members and projects. This helps you make better decisions and makes planning and budgeting easier.

2. More transparency to customers

Transparency is important for customer relationships. One customer portal makes it easy to share hours worked with customers. They can view and approve hours, which builds trust and prevents billing conflicts.

With a well-organized portal, customers can see where their money goes. This makes invoice approval faster and increases customer satisfaction and professionalism.

3. Smart planning and registration

Link your time registration to a planning tool. This way, you can organize your working day more efficiently. By updating your hours daily, you prevent backlogs and keep everything accurate.

In addition, you can use a planning tool looking ahead. Do you notice that certain tasks take more time? Adjust your schedule to prevent unexpected delays and make it easier to meet deadlines.

  • Linking with projects and customers: Record hours per customer and project for a clear overview.
  • Transparency to customers: Share hours worked via a customer portal so they approve, which builds trust.
