Money is an important part of work. Every month, you receive your salary. This is the money your company pays you for your work. Before you receive it, the company takes out tax — money that goes to the government.

Companies also have budgets. A budget is a plan for how much money you can spend. If you buy something for work, like a train ticket or lunch with a client, it is an expense. You can usually get this money back from your company.

Sometimes, if you do very good work, your company gives you a bonus. This is extra money as a reward.

When you send work to a client, you send an invoice. This is a document that says: please pay me this amount of money for this work.
