# Invoice types
Invoice types are labels that classify Your documents in Fitek. They help You distinguish between different kinds of invoices and expenses - and they're visible on the invoices themselves, so users always know what type of document they're looking at.
You'll find them under Settings → Invoice types. Users with the Administrator or Accountant role can manage them.
**What You see on the invoice types page**
The page shows a list of all Your configured types. Each one has:
* **Type:** the category, either "Expense" or "Purchase invoice"
* **Code:** a short code used in exports and integrations
* **Description:** what users see on invoices
* **Is default:** whether this is the default type for its category
* **In use:** whether documents are currently using this type
You can search the list by keyword and sort by any column. Types that are in use can't be deleted without first reassigning the documents that use them.
### **Creating a new invoice type**
Click "+ Add" in the top right corner. A sidebar opens where You fill in:
* **Type:** pick "Expense" or "Purchase invoice" from the dropdown
* **Code:** a short identifier (required)
* **Description:** what this type is called
* **Is default:** toggle this on if You want it to be the default for its type. For example, if You create a new expense type and set it as default, new expense documents will use this type automatically.
If You need to create several types at once, tick "**Add another invoice type**" at the bottom — after saving, the sidebar stays open so You can add the next one without going back to the list.\
### **The default "Expense" type**
When the Expense module is activated for Your company, Fitek automatically creates an invoice type called "Expense" and sets it as the default. This is the type that the mobile app uses when someone submits an expense report. Every expense report that arrives from the app is created as an invoice in Fitek with this type.
{% hint style="info" %}
You don't need to create this one manually - it's set up for You. But You can create additional expense types if You want more granularity, like separating travel expenses from office purchases.
{% endhint %}
### **Invoice types and payment methods**
Invoice types work closely with payment methods, especially for expenses. When the Expense module is enabled, Fitek creates two default payment methods alongside the "Expense" invoice type: "Company credit card" and "Personal credit card."
You can add more payment methods under Settings → Payment methods if Your company needs them. When creating a payment method for expenses, set its type to "Expense" so it's available in the mobile app when users submit expense reports.
Together, invoice types and payment methods ensure that what users see in the mobile app matches how those documents are classified and processed in the web interface.
### **Who can manage invoice types**
Both Administrators and Accountants have full access to this page - add, edit, delete, search, and sort.
