What is a simplified invoice and what does it look like?

Every sale of goods or services should be evidenced by an appropriate document – this is common knowledge. Keeping up to date with all types of invoices and receipts is not the easiest thing to do, especially when legal regulations change relatively frequently and, on top of that, modifications concern only seemingly unimportant details. The most common documents of this type are VAT invoices, sales contracts and bills (receipts). For a good few years (specifically since 2014), sellers have been able to use yet another type of invoice – the simplified invoice.
