Keep track of your costs, with the receipt attached. The year overview then shows your revenue, your costs and what's left.
Adding an expense
Under Expenses, click New expense, or Expense on the overview. Fill in the date, the supplier and a description, and for each line the amount and a category.
Fill in the gross amount: what you actually paid, including any VAT. If you use the KOR, the VAT is optional. If you want to see it, fill it in as well. It's for information only and isn't counted anywhere.
Don't use the KOR? Then fill in the VAT on every line as on the receipt, and choose the VAT rate: 21%, 9%, 0% or no VAT, or reverse charge (Netherlands, another EU country or outside the EU). No VAT on the receipt? Fill in 0 and choose 0% or no VAT. Huismus doesn't compute the VAT: it keeps what you fill in.
Did you pay for things from different categories at once, like a laptop and a bag? Use Add line and give each line its own category.
Receipts
Drop a receipt on the expense, or choose a file: a photo (JPG, PNG or HEIC) or a PDF. Huismus keeps a HEIC photo as a JPG. For a new expense you can do this at the top of the form, before you click Save. An expense can have more than one receipt: add the others after saving.
Receipts from the road can also go in a folder that Huismus picks up itself. See Receipts on the road.
Categories
Under Categories on the Expenses page you add, rename and order your categories. The order decides how they appear in drop-down lists and on the year overview.
Searching and the year overview
At the top of the list you search by supplier or description, and filter by year and category.
Reports → Year overview shows your revenue, your costs and the difference for each year, also per quarter. If you don't use the KOR, those are your costs excluding VAT, with the input VAT apart (see KOR and VAT). You can download a CSV there too, or an export with everything in it. See Exporting.
