The core details
- The date the invoice was issued
- A unique, sequential invoice number
- Your VAT identification number
- The customer's VAT number where the customer is liable for the VAT (for example reverse charge)
- Your full name and address, and the customer's full name and address
- The quantity and nature of the goods, or the extent and nature of the services
- The date of supply, if it differs from the invoice date
- The taxable amount per VAT rate, the unit price excluding VAT, and any discounts
- The VAT rate applied and the VAT amount payable
- A reference to the applicable exemption or to reverse charge when no VAT is charged
Mixed VAT rates on one invoice
If lines carry different rates, the VAT has to be shown per rate. Invoice Generator King does this automatically: each line keeps its own rate and the totals show one VAT row per rate.
Simplified invoices
Many countries allow a simplified invoice for small amounts, with fewer details. The threshold and rules differ by country, so check with your local tax authority.
Keep copies
Businesses must usually keep copies of their invoices for several years. Download the PDF of every invoice you send and store it with your records.
