Why categorise?
Correct categories make your:
- VAT return simpler
- Year-end closing clearer
- Spending insight more accurate
Default categories
Declair offers categories such as:
- Office supplies and materials
- Software and subscriptions
- Travel and accommodation
- Entertainment
- Phone and internet
- Training and courses
You can add custom subcategories under Settings → Expense categories.
Automatic categorisation
When you scan a receipt, Declair suggests a category based on the vendor. For recurring vendors (e.g. AWS, KPN, NS), this gets more accurate over time.
You can set fixed rules: "All receipts from Vendor X → category Software".
Private vs. business
For mixed expenses (e.g. home internet 50% business):
- Enter the full amount.
- Set the business percentage to 50%.
- Declair only includes the business portion in your reports.
Monthly routine
Plan 15 minutes per month to handle uncategorised expenses. Filter in Expenses by No category and update them.
