What must be on my guest's invoice?

As soon as you send a guest an overview of purchased and paid electricity consumption, invoice rules apply, and these differ by country. Frequently recurring requirements are the supplier's name and address, a unique sequential number, date, description, amount and possibly a breakdown excluding/including VAT. Staywatt records the consumption and amounts, but whether your overview to your guest meets the legally required form, you must check with your accountant or the tax authority of your country.
