Elements of an invoice

The requirements for invoices may vary from country to country. That’s why you always need to check the legal requirements for invoices in your country. Nevertheless, it usually comes down to showing the same basic information.

“Invoice” label

Any invoice should clearly state that it is an invoice on its front.

Date and number

Your invoice should have a unique number that follows from the last invoice. It’s also good to keep the sequence of invoice dates, i.e., the date of each invoice shouldn’t be earlier than the date of the previous invoice.

Seller and buyer details

Include the business name, address, contact details. You can also add company ID or tax ID numbers depending on the invoice requirements in your country.

Payment terms

You should agree on the payment terms before finalizing the deal. However, it’s a good idea to duplicate it on the invoice for the buyer’s convenience. Include the agreed payment term and the payment due date. Mention the payment methods you accept and provide the information on how to proceed with them. Udokit allows you to add this information with a couple of clicks! Ideally, your invoice should have all details that the buyer needs to process the payment without checking the contract or email communication with you.

Pricing table

The table should include a description of the goods or services sold, price and quantity per item, rate of any discount or tax applied.


Show the subtotal, total amount of tax, and total amount including tax.
