A correct VAT invoice, convenient online issuing and preparation for KSeF.
A correctly issued VAT invoice is one of the most important documents in business activity. At Good Balance we offer convenient online invoice creation in line with the current tax regulations in Poland, including preparation for the mandatory KSeF system.
The list of mandatory elements of a VAT invoice is set out in detail in Art. 106e of the Polish VAT Act.
A well-prepared invoicing system helps you avoid mistakes, speeds up settlements and organises the document flow within the company.
Every invoice should make it possible to clearly identify the document, the parties to the transaction, the subject of the sale and the tax amounts.
The most important data can be divided into four practical groups.
Group 01
The invoice should clearly identify the document and the parties to the transaction.
Group 02
Each line item requires a description, quantity and unit price.
Group 03
The values section gathers the amounts needed to settle the tax.
Group 04
Depending on the transaction, an invoice may require additional annotations.
The invoice should clearly show the subject of the sale, the net values, VAT and the total amount due.
The document should specify:
The description should be clear and consistent with the actual sale.
The invoice should include:
Amounts should be stated in a way that allows the tax to be settled correctly.
Depending on the transaction, the invoice may contain:
Special markings depend on the type of sale and the taxpayer's status.
— 01 · sale
An entrepreneur should issue the invoice by the 15th day of the month following the month of sale.
— 02 · customer's request
When the customer requests an invoice, the document must be issued within the statutory period counted from the request.
— 03 · advance payment
In the case of an advance payment, the invoice is issued by the 15th day of the month following receipt of the payment.
Procedura VAT marża allows you to settle tax only on the margin, that is the difference between the sale price and the purchase price. It applies, among others, to second-hand goods, works of art, antiques and collector's items.
Invoices may be issued in paper form, in electronic form, e.g. PDF, and as structured invoices in KSeF.
With Good Balance, invoicing becomes organised, secure and ready for KSeF.
At Good Balance we help companies issue invoices online, get ready for KSeF and run settlements safely.
